I am wondering what the next post is going to be though. The database might not have anything in it. You know, like tables!

heloo guys.. u really doing agreat job ..any way i have created strings for each shape (lines,polygons,..) each string contains informations about the shape( x1,y1,x2,y2,R,G,B,pen width) ..Now how can i make my prog read from the text and draw the shapes ..as example the line string :
public void AddSv(Line l , ref string str)
{
if(drawwhat==1)// as one means lines
str +="1"+"\n"+l.First.X.ToString()+"\n"+
l.First.Y.ToString()+"\n"+
l.Second.X.ToString()+"\n"+
l.Second.Y.ToString()+"\n"+
l.Pen.Color.R.ToString()+"\n"+
l.Pen.Color.G.ToString()+"\n"+
l.Pen.Color.B.ToString()+"\n"+
l.Pen.Width.ToString()+"\n\n";
after i draw the line i click on save to send the informations to the text :
private void button1_Click(object sender, System.EventArgs e)
{
//save
System.IO.FileStream fs = new System.IO.FileStream("c:\\graphics.txt", System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write, System.IO.FileShare.ReadWrite);
StreamWriter streamWriter=new StreamWriter(fs);
streamWriter.WriteLine(LineSv);
streamWriter.Flush();
streamWriter.Close();
fs.Close();
}as u can see i dealing vs 2003 .
Regards;;)

you need to read the string, then you need to parse it. It would make more sense to put commas between data items, so each shape is a line of text. They read the file as a string[] and call string.Split on each line to turn 1,2,34,5, into an array of strings, which you can then turn into numbers with int.TryParse. You can read the first number and use it to decide which function to send the array to, so that it can be parsed and objects added back to your array.
It would make more sense for the Line,Square,Triangle,Circle,whatever classes to offer a method that returns the string, so you can just iterate over your collection of base objects and call it.

I may have hit myself in the head, but didn't we have an XmlSerializer class laying around somewhere?

do u mean like that :
if(openFileDialog1.ShowDialog()==DialogResult.OK)
{
StreamReader streamReader=new
StreamReader(openFileDialog1.FileName);
string m=streamReader.ReadToEnd();
string []x= m.Split();
MessageBox.Show(m);
streamReader.Close();
}
but this displays all the data in the file even after putting commas between data like 1 23 38 0 0 0 1 ,2....
iam lost !

I think I've suggested several times now that you abandon this project, it is obviously beyond you.
What else did you expect it to do ? You've done one part of what I said, although not quite how I said it, and shown the strings on the screen, what else could happen without more code to do it ?

Well, don't give up entirely. Just work through some other stuff so you're better able to understand the advice you're being given. I'm still trying to help, not to shoot you down in flames.

I have 2 tables linked but I cannot seem to get any data to populate the subreport
I am at a loss. Is it possible to have 2 setdatasource statements.
I have a sub report which populates fine, just passing params
then the main text which pulls from a sql db which is fine and another
subreport which the headers shows up okay (I pass params to get the header text, but the data which is from another sql db does not show up. it must be something in the below snippet I am doing incorrectly. I am using dataadapters.

In a filewatcher I want to test to see if a file is complete. I tried this:
File.Open("c:\test.txt", FileMode.Open, FileAccess.Read, FileShare.None)
I don't get an exception when the file is open with Notepad.
How can I detect the file is opened by another program?
Thanks
|

Notepad doesn't lock a file open. It opens a file for Shared access, reads the file and closes it immediately.
When it goes to save the file, it opens the file for DenyShareAll, writes it out, then closes it.

That depends on the behavior other program, as you've already found out.

Reliably, for any application?? You can't.

Hi,
Am a total newbe to VB.NET so please be gentle.
I have been tasked with writing a front end to a Fortran program that my company has, basicly the front end writes a text file then calls the fortran program to process the text file thus creating a set of results. All is going well, I can create the file and call the Fortran program but I can't see how to send the name of the file I want to process to the Fortran program.
The Fortran prog will not accept arguements. I have tried using the send keys option but all it sends is a \ character so can anyone help or point me in the direction of an article that may help?
regards,
Matt

That depends on the Fortran app. If it doesn't accept any command line parameters, your project just got that much more difficult to control.
It MAY be possible to use SendKeys, but this is problematic. If the app you launch isn't ready for input, you're sending keystrokes to no-mans-land. When you launch the app using the Process class, there is a method called WaitForInputIdle that will cause you app to stop and wait until the launched app finishes starting up and enters it's idle state.
|
|
|
|
|
Ok will try that, have tried forcing a wait by opening the prog then using a message box then sending keys to the app but all this does is place a \ charcter in the frotran app.
regards,
Matt

|

No real choices. Controlling another application that doesn't have any kind of remoting abilities is a crap shoot at best.
After the messagebox line in your controller app, did you make sure the Fortran app has the input focus?
The last option is rewrite the Fortran app!

I would like to know if anyone knows of a website that will explain and give lots of examples of VB 2005 Deployment Condition property syntax. I want to be able to set the condition so that if the a file is already installed it wont be overwritten or cause errors. I am using Windows Installer 3.1. I do not want to use other installers and i know its possible.
|

|

Hey guys, I have been creat a service and it is just about finished all i need to do now is creat the deployment project and the question that i have is this. Is there any way to have the service start automatically right after the the install is finished? I know there are custom actions that I am sure can do this but I dont know how to get that to work.
Please help and thanks again in advance.

Hello, I am trying to look in a table to see if the item already exisits before I add another one. I have a simple table with 2 fields. The primary key is one and it is an auto number, the other is the description that I am trying to check for.
The name of my table is OrdersListBoxInfo and the table name I am trying to compare with is Order. Once I get to the line "Count = cmd.ExecuteScalar" I am getting error "No value given for one or more required parameters."
Here's the code I am running. Can anyone tell me what I am missing/doing wrong?
Dim OrderName As String
OrderName = txtOrderName.Text
'Check to see if this Order already exisits
Dim Count As Integer = 0
Using Connection As New OleDbConnection _
("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Documents and Settings\Costco\My Documents\Visual Studio Projects\AnesXL.mdb")
Dim cmd As OleDbCommand = New OleDbCommand _
("Select Count( OrderName ) as ExistingRecords From [OrdersListBoxInfo] where [Order]=?", _
Connection)
cmd.Parameters.AddWithValue("@Order", OrderName)
Connection.Open()
Count = cmd.ExecuteScalar
End Using
If Count > 0 Then
MessageBox.Show("Number of rows found: " & Count, "Add Date", MessageBoxButtons.OK)
Return
End If
|
|
|
|
|
You said in your description you have two tables. But, this operation you're describing is only working on one table. Which is it? Shouldn't the WHERE clause lok like this:
SELECT COUNT(OrderName) As ExistingRecords FROM OrdersListBoxInfo WHERE OrderName=?
I also don't like using AddWithValue. It leaves too much up to interpretation by the OleDbParameter class. I'd do it like this instead:
cmd.Parameters.Add("@OrderName", OleDbType.VarChar, 50).Value = OrderName
You might also want to validate what's in OrderName before you assign the value to the parameter.

I’ve got a function for sending a file to a remote host wich Is as follows
Public Sub SendFiles(strTemp As String)

strTxtFile = "c:\trace.txt"
Open strTxtFile For Output As #1

The problem is that I don’t have a way of knowing whether a file has been transferred successfully or not
Pls help

This has the makings of a nightmare...
First, you're app is writing a script file, then launching an external application which executes the script. Is this FTP a DOS app or a Windows app?? If DOS, then you need to pipe the FTP app's output to another file using a command line similar to:
ftp -s:scriptname > C:\ftpOutput.txt
When the Shell statement returns, you have to open the ftpOutput.txt file and read its contents and parse it up, looking for keywords that should tell you if the transfer was successful or not.
This WILL NOT WORK if FTP is a Windows app!
The best solution is to scrap all this and rewrite a new app using an actual FTP component in your app where you'll have FAR more control over the transfer process and the results of it.

I don't have any VB6 examples. I haven't used it in about 6 or 7 years now...
Googling for "VB6 ftp example" reveals a bunch[^] though.

Does anyone understand why when i put an image in the background of a form that it displays correctly for approximately 5 seconds but then the same image is applied within the window overlapping the first image but offset. The only way i've found to get around this is to set the 'Show in taskbar' to false.
I've also found that if i minimise the form and then restore it, it does exactly the same thing, the image in the form appears okay for 5 seconds and then does this overlap thing.
The form is approximately 800x600 pixels and set to appear in the centre of the desktop. If i set the form to 'manual' and have it start at position 0,0 then the overlap thing doesn't occur, or if it does, then it's not obvious as it must be overlapping in exactly the same position.
Any ideas other than putting it into a picture box, which isn't an option as i have text with it's back colour set to transparent, and the transparency is obviously lost if i put text over a picture box.
