Did you do the walk-through I posted the url to in the above comment?

JOAT-MON 5-Jun-13 3:06am View

Nice, glad it helped :)

JOAT-MON 13-Mar-13 3:06am View

Ok, I believe what you are looking for is:

// if your Button.Click event is handled inside the scope of the Main_View partial class,
// then you should be able to reference the tabControl1 object from inside
// the Button.Click event handler
private void btnExitbutton_Click ( object sender, EventArgs e)
{
tabControl1.SelectedTab.Dispose();
}

// if your Button.Click is handled inside the scope of the TabPage class,
// then you will want to use the 'this' keyword to reference the page you are on
private void btnExitbutton ( object sender, EventArgs e )
{
this.Dispose();
}

Let me know if I am misunderstanding you.

JOAT-MON 12-Mar-13 14:02pm View

I'm sorry, I don't understand the problem that you are trying to describe. Could you please clarify? (i.e. Are you trying to communicate between two forms, two tabpages, or two files of the same class? Is the purpose of the button to dispose of the form, a single tabpage, or all the tabpages?)

JOAT-MON 4-Nov-11 18:50pm View

Ouch, fair enough. I should have looked at the structure before submitting. My mistake.

JOAT-MON 1-Nov-11 19:02pm View

It has to do with basic understanding of programming. It also has to do with the math issue you pointed out, but there is a real programing problem here as well: fundamental understanding of the use of variables and following the spec.

All server engines have their own proprietary syntax and functions. The OleDb provider that you used is the Microsoft JET Engine, which is different from the SQL Server engine, and therefore has its own way of parsing the query and compiling it. As you access different databases, realize that there will be slight differences in the syntax of the T-SQL that you use in your queries.

JOAT-MON 7-Sep-11 5:42am View

This is not a Load function, it is the event handler for the OnLoad event. It gets called after the form instantiates, but before it displays. It is intended for setting properties and values on your form and its controls before drawing them. See my updated answer for help on what I think you are trying to do.

I have no idea about that, I have not done any work on webcam streams, but it sounds like it has potential. Do a search on CodeProject, I think this has been addressed before, there may be an article or answer that can help you to accomplish it. Good luck!

JOAT-MON 8-Aug-11 15:53pm View

Nevermind, I see you have another thread started to focus on the visibility. I will add to it if I think of anything that hasn't been addressed already there.

JOAT-MON 8-Aug-11 15:29pm View

I just created a test app that mimics this scenario and the visibility worked fine. I think I will need more info from you about what you are doing to be able to see why the visibility does not work for you.

item1 item2 item3 item4 item5

JOAT-MON 7-Aug-11 1:41am View

I understand your problem, maybe you misunderstood my solution? Notice that I have added an ending curly brace in there. It looked to me like you were missing this in your code, which would cause the foreach loop to break out of its iteration after the first comparison, whether it matched or not.

Added code block.

JOAT-MON 3-Aug-11 1:06am View

Based on this article:
http://www.codeproject.com/KB/vb/StepByStepEventsInVBNET.aspx
it looks like you need to add WithEvents to your button declarations. Take a look at the 'Handling events (static)' section.

I agree with Walt. 'COMPLAINT' may be a string in another table that needs to be joined on the numeric value in the PHASE column. Hard to tell with out knowing what the structures are.

JOAT-MON 25-Jul-11 14:53pm View

Ok, just created a sample project, during run-time if you scroll the panel, the PictureBox.Location will already reflect the offset of the AutoScrollPosition. If you are getting a point using one of the Mouse events on the PictureBox, then the offset from the Panel.Location of the point will be:

OffsetFromPanelLocation = PointInPictureBox + PictureBox.Location

JOAT-MON 25-Jul-11 13:38pm View

I need you to give me a better description of what "it doesn't work" means for me to help. Are you getting an error? Is the resulting point not where you think it should be? Are you certain the point you are trying to calculate is being captured by the PictureBox (as opposed to being captured by the Panel)? Can you share the part of your code where you are trying to calculate this?

JOAT-MON 23-Jul-11 16:04pm View

my 5 - OP does not need a 'Hello World' example...he needs a 'Goodbye Virus' example. :)

JOAT-MON 21-Jul-11 16:26pm View

I think the point's offset relative to the Panel.Location = PictureBox.Location + PointInPictureBox + AutoScrollPosition

That is a fantastic question. Looking back over the question, I think it was the attempt to assign the Size property of the Font, got me thinking he might be trying to do this in code behind, but now that you've brought it to my attention again, I don't see a reason. Hmm...

1) try wrapping Huntsville in double quotes in the first two samples above
2) try breaking up the CONTAINS into two phrases...see [EDIT2]

Maybe the issue is having the AND inside the token...see my [EDIT] above.

What is your process for drawing in the panel? How you remove the drawing is in part relative to how you put the drawing in there.

JOAT-MON 9-May-11 14:46pm View

@JSOP 5

@umairshoaib: Your query specifies the Id in the WHERE clause, so you should only be receiving one record for the user you specified. If you want more users to return from your query, you need to remove or modify the WHERE clause.

I am not sure what your question is, but you cannot do a partial implementation of an interface. You must implement the entire interface if you are going to inherit from it. But so far your implementation is looking fine (just incomplete). Is there a particular problem that you are having?

At the bottom of the article is a section for comments and discussion, you should make your observation there so the author will be alerted directly.

JOAT-MON 12-Apr-11 21:20pm View

Understood, well the key will be looking for a section of the code where you get the image: it is probably keeping the file open. Once you have the stream in memory you will need to release the file so it can be overwritten.

JOAT-MON 12-Apr-11 20:43pm View

Could you update your question to include the C# code you are using to get the image from the file and assign it? (Chances are that something is holding on to the file)

Lol...yep, missed it. My brain filtered out the comments in your answer. :)

JOAT-MON 8-Apr-11 23:03pm View

5 - I agree with your answer, however, OP still needs to assign a value to his variables or his results will never reflect anything practical.

JOAT-MON 8-Apr-11 19:01pm View

You have not assigned any value to totalUnits or totalRefurb after initializing them to 0. You need to assign a value to them from the rows that you read in.

For instance, right now you are running a scalar query that returns the total refurbs for a particular order. If this is the intended value that you are trying to get a rate off of, then it needs to be assigned to totalRefurb before the calculation. Also before the calculation, you need to get the total units from that order and assign to totalUnits.

JOAT-MON 14-Mar-11 17:07pm View

I would caution against this because when someone tries to click the button and their mouse is not stationary (like when they are clicking quickly), it will try to drag and may even drag far enough to drop and reorder, which could be frustrating to them. This is why there is a requirement to hold ALT key down, so the items know they are explicitly being reordered. <-- My two cents :) As far as getting the functionality, I don't think it will be there innately, but you might look at setting the ALT key programmatically to trick the control. Otherwise, I think you will be left with coding it yourself.

JOAT-MON 9-Mar-11 15:05pm View

The saddest part is, I saw the property (didn't read the description) and thought to myself 'That will prevent the splitter from moving at all..that's not what he is looking for.' :doh:

JOAT-MON 9-Mar-11 14:04pm View

Yeah, I re-read the property list several times to no avail, then I tried a bunch of combinations of the properties that seemed relevant and none seemed to work out, so I threw this together.

JOAT-MON 8-Feb-11 17:43pm View

So true. We could probably create a rather big page full of alternatives to accomplish that. :)

JOAT-MON 8-Feb-11 17:28pm View

+4 Utilizing a bitmap is a valid alternative, but if you look at the OP's code, he is trying to create an 8 X 8 board, not just the pattern as a background. For the OP's scenario, he would need to have a bitmap that was his full board(8 X 8) and ImageLayout not set to Tile.

JOAT-MON 8-Feb-11 5:03am View

Understood, the point I was making is that he is not drawing from the Control class, but rather from the Form class. The Control.DoubleBuffered is protected virtual, and the Form class implements it as a public property: http://msdn.microsoft.com/en-us/library/system.windows.forms.form.aspx

I felt it was relevant because Form class is the level at which the OP is drawing, meaning it is not necessary to create your own control...the DoubleBuffered is already publicly implemented for this class.

JOAT-MON 8-Feb-11 0:20am View

Not certain, since I do not use MySql, but you could try using one connection for access and another for insert/update since they are not returning result sets. This would get you down to two connections. I do not know how much other stuff is going on in your program, but in mine I still close the connection, though not dispose, if I am doing anything else between database calls, in case the program throws an exception or something, I do not want to leave my connections orphaned.

JOAT-MON 7-Feb-11 23:36pm View

Just one thing, he is painting from form: Form.DoubleBuffered is public. (+5 agree with advice)

JOAT-MON 7-Feb-11 22:26pm View

Yep. It is the only way I can think of to circumvent the error you were getting and accomplish the simultaneous access/update/insert you are after.

JOAT-MON 7-Feb-11 22:16pm View

Create multiple connection objects to use with your multiple threads. Each thread will need its own connection if they are operating simultaniously. Just be sure to close/dispose them when they are not in use.

Good point, if it is not in the currently executing assembly. I will modify my answer to address this.

JOAT-MON 4-Feb-11 15:32pm View

The error seems to indicate the absence of the requested location rather than the timeout of the request. Have you checked to see if the location you are requesting has been changed(i.e. moved, renamed, etc.)? Can you access the location through your browser as opposed to your service?

JOAT-MON 3-Feb-11 16:52pm View

Just tested it, even if you assign an Owner to it or wait on the MessageBox response the timer will still march on. (using the System.Windows.Forms.Timer VS 2010). OP must be using a different timer, or something else not indicated in question, that is causing the issue. Looks like he likes the workaround provided by OriginalGriff, though.

JOAT-MON 3-Feb-11 15:02pm View

This example is not a reproduction of the OP situation. The OP has the MessageBox.Show() in the timer_Tick() handler. To get a better sense of the issue, move the MessageBox.Show() into the timer_Tick and see if you encounter a problem with the Timer continuing while the MessageBox is displayed.

Oh, okay...what you really need is just the Random class, not the foreach loop. Foreach is just for doing an iterated walk of collections.

JOAT-MON 28-Jan-11 18:53pm View

The error is apparently not obvious, given what we know about your setup. A couple questions to help us identify what is happening (any additional information will be helpful):
1. Does the employee_details table already have rows in it? There is no 'WHERE' clause to specify which employee's details you are trying to update, are you trying to update all rows in the table with the same information?
2. Is it possible you want to 'INSERT' this information, rather than 'UPDATE' it?
3. What version of the MySql client are you using?
4. How is your command setup? What is the CommandType? Are you using ParameterCheck?

JOAT-MON 28-Jan-11 13:47pm View

Agreed! That is why I began to think that the OP had custom controls. I did not put the adding of the control in there since Theingi Win had already suggested it, but it would be highly likely. :)

JOAT-MON 21-Jan-11 21:22pm View

Sounds like what you want is to use the MouseDown event to get the starting point of the rectangle. Then use the MouseUp event to get the ending point. The difference between these is the size of the rectangle. You can put it in a number of different events or functions, depending on how you are using it, but to get the feel for it I would start by putting it in the MouseUp.

JOAT-MON 19-Jan-11 16:26pm View

Suggestion: I don't have an answer for you off-hand, I haven't morphed images in this manner, but have you looked at the capabilities of either the GraphicsPath class and/or Matrix class to accomplish this?

JOAT-MON 18-Jan-11 3:19am View

You're welcome.

JOAT-MON 18-Jan-11 1:59am View

@gunkrr - If you are using the ImageLocation property or the .Load() function of the PictureBox to set the image initially, then you can pass the ImageLocation property to the .Save() function.
If you are creating a bitmap, or other image, then setting the Image property, not using the ImageLocation property, then you can store the path to the image file in the PictureBox.Tag property and pass it as a string to the .Save() function.

JOAT-MON 11-Jan-11 19:42pm View

@RajxC - Each of the array elements in this._dataArray1 are double[] that contain one element. When you say foreach(double number in this._dataArray1[i]) you are telling it to iterate through the double values in the double[] located in the 'i' index of this._dataArray1...there is only one value in that array at that index.

When you use the while loop to assign values from junkarray, you are splitting up the array and creating five new arrays with one element in each. What you can do to mimic the hard coded way is to assign like this: _dataArray1.Add(junkarray) <-- notice I did not specify an index.

Given the way you have written it, you need to assign the Header property. Add this line before the 'if' block:
liViGroup.Header = "Starter";
This will always get you into the 'if' block where you are adding items.

In addition to the questions raised by Henry Minute:
1. Are you calling the .msi from a C# program?
2. If this is a third party .msi, have you checked to see if there are command line parameters that can be passed to set those values for you?

What you will be creating are a series of lines that look like they connect PictureBoxes. So the coordinates you assign to the endpoints when you draw the lines should be on the border of the PictureBoxes that you want to connect.

From what you've told us, it implies that the designer is having trouble rendering the form. Two possibilities are 1) you made a modification to a control that the designer can't interpret, or 2) it is having trouble updating the controls that are already on it. Try closing the designer page and reopening it to eliminate the second possibility. If that doesn't help, you will probably need to look at the modifications you made to the control.

Just miscellaneous variable names for points to use in the drawing...you can use any name you want to. I used those for the example to show the direction of the line drawing. They represent the endpoints of the line you want to draw.

Actually, it doesn't seem to matter; everything I am reading on MS Access indicates that it does not import relationships from xml. You will probably need to create the relationships in MS Access initially.

JOAT-MON 23-Dec-10 12:15pm View

Did you understand my two questions? I will rephrase them:
1. Do any of your relationships show up when you import?
2. When you write the dataset to xml, do you specify that it contains the schema?

Process.GetProcessByName() is a static function that will search the currently running process list for a process with the name you pass to it as a parameter. It returns an array of processes, so if that array is .Length == 0 then the process is not running. However, if the .Length > 0 then the process it was looking for is running.

In your [StructLayout()] attribute there are named parameters. One of them is CharSet. Set it to CharSet.Unicode.

The numbers are just really big integers. They are expressed in exponential notation where:
e means exponent notation, + or - means the direction left or right of the decimal, and the number on the right is the number of zeros.

By default, the Nested property is false. I have not had any problems serializing when this is the case. The serializer will simply write out each table individually without trying to nest the rows.
And no need to apologize about the English. :)

JOAT-MON 17-Dec-10 4:13am View

It is not because it is the last relationship added, it is because it is the one that is contradictory to the other relationships. If you allow for relationships to be dynamically added, then you will need to do a little validation to make sure that if the relationship is nested, then the specified child does not already have another parent in the Relations property.

Right, otherwise the DTP will utilize whatever cultural context it is running on to determine the display format.

JOAT-MON 11-Dec-10 15:11pm View

Still an issue with scope: the particleArray that you are initializing in the constructor is scoped local to the constructor. To initialize the class level array to the proper size, do not include a declaration in the constructor:

public partial class ParticleBoxForm : Form
{
Particle[] particlesArray;
int numParticles = 100;

public ParticleBoxForm()
{
InitializeComponent();
particlesArray = new Particle[numParticles];
}
...

@Marcus - Makes sense...I think I had it in my head that there would be an empty object there. Edited answer to include your recommendation.

The select clause will be like this:
sql = "select A.FileLoc, A.Fname, A.Lname, A.dept, A.role, A.rating, A.notes, B.firstdegA, B.firstdegB, C.secdegA, C.secdegB, D.thirddegA, D.thirddegB, E.dipA, E.dipB, F.hndA, F.hndB, G.phone_one from ... where ..."

The FileLoc is still in the tables and can be used for joining, but you do not need to have it returned from every table. The select clause is for identifying which columns you want to receive from the database, the joins tell the database how you want your tables to be related to each other when you're doing the selection.

The .FromStream() will work, but you have to ensure that the stream is not connected to the file, or a direct read of the file, or else the file remains locked up. See 'Modification' section in my answer above to create detached stream from file.

Oops, sorry...not the use of .Commit() but where it calls it...don't know if this has an effect on how it behaves. The example calls the commit from outside of the command object.

Regarding: {"You must enter a value in the 'RAW_Transaction_Data.post_tran_cust_id' field."}: Is the 'RAW_Transaction_Data.post_tran_cust_id' field set to allow NULL value? Or, is it set as PrimaryKey? (both situations would require data to be present) This is likely to be related to the {"Syntax error in INSERT INTO statement."} error if the field requires a value and it receives a NULL.

JOAT-MON 2-Dec-10 14:02pm View

Since it is intermittent, I would agree with Thomas Krojer (comment above) that it could be the format of the data being passed in. I think he is concerned about the format of the data being passed to the datetime field (F5), which makes sense. Can you check your data and see if there is a difference between the data rows that succeed and the ones that fail? Or post a small sample (rows that succeed and rows that do not)?

It might be helpful if you include a couple code snippets:
1. show how you are reading the file in (to see if you are getting the entire file)
2. show how you are printing the file out (to see if you are printing everything from the file)

JOAT-MON 1-Dec-10 19:20pm View

1. What do you mean by 'I am unable to get this to insert the new rows every time.'? Does that mean that it does do the insert some of the time?
2. Have you tried the selection query with out the insert portion to ensure that you are getting rows returned?
3. Have you stepped through the code to identify where it is problematic? (i.e. connection, retrieving data, inserting data, etc.)
4. Is it safe to assume that 'CreateConnection()' will instantiate 'dbconn' correctly?
5. Is it possible for DBTableName != "RAW_Transaction_Data"? if so, it looks like your code will still pass the incomplete query to be executed.

I run on XP SP3. From everything I have heard, most Vista versions have had a lot of unusual behaviors, so it may be a side effect of that. If you have the opportunity, you should try it on a different operating system and see if that has an effect. Good luck!

I don't think the version of VS matters (whether Premium or Express). I tried targeting my project to .NET 2, .NET 3.5, and .NET 4 to see if it made a difference...it didn't matter, it still worked no matter which .NET was targeted.

1.) Whenever you click the button it fires a series of events including the MouseDown. If you double-click the button it will fire the events twice, because it does not inherently support the DoubleClick event. I would check to see if you have more than just the MouseDown event hooked(i.e. MouseClick, Click, or MouseUp). If any of these events are being handled in your code, they will also be called twice when you double-click. If they are being handled, look to see if they call the editToolStripMenuItem_Click event as well.
2.) Search your code for the places that you hook to the event (syntax will look something like: newbutton.MouseDown += new System.EventHandler(newbutton_MouseDown) ) and make sure that it does not register more than one handler to the MouseDown event.
