I am calling the binding source programatically instead of dragging and dropping the binding source and table adapter into the forms. When I was using the designer to create the binding source, data table and table adapter the forms designer was generating code that caused the desginer to not show up.

I need to execute a query to a table names tbl_store_sched where if the table column ss_day has a row that has Monday in it then the monday checkbox will get checked and the selected value for a combo box will be the same as the column ss_from. The combo box is populated from tbl_hours.
I figured I would use the tableAdapter.FillByTableColumn method but when I write the code the words fillBy end up with a blue line under them.
Is the TableAdapter.FillBy method the best way to do this?
Is there a way to just get all the results from the database table and then check those results to see if the rows exist or what information is in the row?
Can I just fill the dataTable using schedTableAdapter.Fill(lpDataSet.tbl_store_sched) and then get the results from certain rows and columns?
I will need to use data from this table for several checkboxes and combo boxes and I don't want to have to execute multiple queries.

You're getting the quiggly line because your tableadapter doesn't have a method called FillBySomething. You have to right-click the methods in dataset designer and click "Add Query...", supplying the SQL statement and options to generate the FillBy... method code.

Would it be better for me do a bunch of fillBy Methods or to use a binding source?
Wouldn't it slow my program down to do a bunch of FillBy Methods, being that each time I do it is represents a database query?
I have about 14 different combo boxes that all populate from the hours table. The difference between them is that when the user chooses a time in the combbo box they each store that time in the database and then when the user navigates to the store schedule tab the value that was stored in the database is the selected value in the combo box.
Here is tbl_store_sched
create table tbl_store_sched (<br />
ss_id int NOT NULL IDENTITY(51000,1),<br />
store_id int,<br />
ss_day text,<br />
ss_from text,<br />
ss_to text,<br />
primary key(ss_id),<br />
foreign key(store_id) references tbl_store(store_id));
If the user checks the Monday check box. They then will proceed to select a from time and a to time. Once they do this the day "Monday" is stored in the column ss_day and the from and to time are stored in ss_from and ss_to.

That depends on what your app does and the design of your app. Noone can tell you either way.

If this is what your business rules require, then yes, you put these in.

As for the rest, it looks like you really need to rethink how you're storing data in your tables. If a column is storing only the day of the week, you really don't want to do it using the full name of the day. A number field would do it and take up far less space in the database. Also, you're storing times as string in the database - wrong. Store them as time values, not strings. This will make data retrieval much easier and you'll avoid weird results with sorting and functions.

If I am going to store a time such as 3:00PM in the database and store it as a time not as a string, should I be using a date time picker? As far as I know the date time picker will not do time only. Right now I am using a combo box that has a list of times to choose from.

That doesn't change the fact that you're making a big mistake storing time values as strings in the database.

Initial Problem:
When Imaging numerous computers, they use the same SigmaTel device - and the DeviceID is the same. However, each different model MUST use a different driver version or the SigmaTel sound driver will not function. (That's messed up! - who wrote these Gateway model drivers!)
So... we're trying to develop a script that recognizes/pulls the DeviceID and Model, then depending on what computer model and DeviceID is found, then the correct driver should be loaded.
The VBS problem: The IF statements do not seem to be reading in the string variables (the objItem.Name). It does not seem to read it and is blank.
Anyone have any suggestions / solutions on this one! Any help is appreciated.

The problem could very easily be with WMI. Mmotherboard/machine/device manufacturers are not required to provide any information to WMI about the components. If they do, it's usually not complete information either. It's also entirely possible that some devices from a manufacturer will fill in some of the details and others won't fill in any at all.
|
|
|
|
|
WMI and the script appears to be capturing the name.
After looking at this a little bit further, it appears objItem.Name does not return a "text" string, therefore, our IF compare never produces a match.
Is there a way to get the return value to be read as a text string?

That depends on the object returned by Name. It should be a string, but could also be Nothing or some other object. The only way to attempt a conversion is to wrap it in a CStr() function call.
Dim name = CStr(objItem.Name)

How do I determine the output directory of a project (the place where temporary files are extracted)?
Many thanks!
|
|

Your question doesn't make any sense. A "projects" output, when compiled, ends up in the bin folder under your project's folder.
When an installer unpacks itself, the files can go either in a folder hard coded into the installer, or one of the Temp folders, like C:\TEMP, C:\TMP, C:\Windows\Temp, ...
What are you trying to do with this ability?? Is this code that's running in an installer as a custom action??
|
|
|
|
|
Change it in the project properties, it can dictate which folder the files are stored in, and you can set where you want the compiler to output the debug and exe files

This one really has me stuck. Like the subject says, I would like to open a word document that is an embedded resource in my vb.net application.
Up to now I have been able to open a new document with automation:
oDoc = oWord.Documents.Add
or open an existing doc on my hard drive:
oDoc = oWord.Documents.Open("path and filename")
I have little clue, however, how to successfully refer to an embedded document and open that with word automation. Ideally, I would like to do this without actually saving the embedded doc to the user's hard drive first (if possible).
Thanks for your help,
Craig

Can't be done. In order for Word to open the document, it MUST be a file on a drive. It does not have the ability to open a file from a resource, nor a .NET stream object.
The only way I could think of that simulates this, would be to come up with your own script that tells your code how to build a new Word document.

assuming a little different situation, but you´ll get the point:
picBox.Image = My.Resources.ResourceManager.GetObject("smq")
and for writing a ressource to a file:
Dim x() As Byte
Dim bw As New BinaryWriter(New FileStream("c:\fwd.doc", FileMode.CreateNew))
bw.Write(x)

Hi,
Can I connect with visual basic.net to a online server (I have a space on the server with my hosting company, the server has mySQL database on it.)?
The idea was to totally wok online using mySQL server?
Thanks.
|
|
|
|
|
Sure. Exactly how you do that depends entirely on where you're code is going to be running and how your ISP exposes the MySql server to it.
You can get the MySql data providers classes from here[^].
You can also find a pretty good tutorial on using it here[^].

Hi,
While creating the setup of your application, right click on Application Folder and Add -> Assembly to the Folder.
It will open .NET assemblies window. Select all the crystal-report related assemblies.
When u will build the setup project u will obtain a installer for crystal reports. First install this setup and then install your application.
This should work.
Regards,
Ujjaval Modi

Hi,
Even I am not much good at crystal reports but even I faced same problem in my application for crystal reports and I learnt to add its Installer, so I helped you out in it.
Regarding this problem, your Logon to database is failing, thts why your report fails to load.
Try this code :
<br />
<br />
dim rptObject as new ReportObject <br />
rptObject.SetDatabaseLogon(username,password)<br />
rptObject.SetDataSource(dataTableObject)<br />
crv.ReportSource = rptObject <br />
<br />
Here rptObject is an object of your "enq.rpt" report.

Hello All,
I have an application, in which I use also DataGridViews to display data. When the user modifies (delete, modify or add) a column he cann save the data by clicking on a button.
Code :
Private Sub btnToeveoegenBewolkingLicht(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Try
Me.BewolkingBindingSource.EndEdit()
Catch ex As Exception
MessageBox.Show(ex.Message, "Fout bij schrijven data")
End Try
Me.SaveDataBewolking()
Try
Me.LichtBindingSource.EndEdit()
Catch ex As Exception
MessageBox.Show(ex.Message, "Fout bij schrijven data")
End Try
Me.SaveDataLicht()
'ResetControls()
End Sub
In SaveDataBewoling() I check if there are any changes and when so the tableadaper is updated.
Code :
Friend Function SaveDataBewolking() As Integer
'Hier IsUpdating
Dim rowsSaved As Integer = 0
Try
If Me.CarpDataSet.HasChanges Then
rowsSaved = BewolkingTableAdapter.Update(CarpDataSet.Bewolking)
End If
Catch ex As Exception
End Try
Return rowsSaved
End Function
Everything seems to be working OK, but ...... there is no data saved in the files. The new/mod data cann bee seen in the gridview, but the data is not being written to the database.
Maybe one of you cann help me solving this problem. I must be overlooking something but what ?!
