I have a combobox with 12 numbers listed in it. A user can either select a number, or type it in. I have a command button that will push the selected item into a local database. When I go back to the form, I still see the selected value.
How can I have that selected item cleared once the data is saved to the database? I know i can use this: cboSelectedItem.text = ""
However, if I have 50 comboboxes, that would be kind of tedius.
All my textbox controls seems to clear the data fine, because I have it bound to a dataset so when I clear the dataset, the data in the textbox items clear as well.
So I tried to have a collection of items on my combobox plus have it bound to a bindingsource, but Vb.net didn't like that either.
Any advice is greatly appreciated.

i think one way you can follow is to define a variable as Controls....and then put a for loop for each variable in Controls.....then u can have a if statement or case statement inside which can filter all the Comboboxes and in that block u can clear the combobox.....and one thing is "Control is the base class for Buttons, ComboBox, Textbox etc. You may need to cast to appropriate type."
this could be something like....
Dim ctr As Control
For Each ctr In Controls
If TypeOf (ctr) Is ComboBox Then
CType(ctr, ComboBox).Items.Clear()
End If
Next
like that it can clear all the comboboxes in that form.
This could be one way. anyhow may be you have to format the code a bit, this is just an idea though

I am trying to build a program that will select 10 random user names from a list. I need this program to then store that list in a file so that when i run the program again it will not select those ten users. Does any one have any ideas where i can get a start on this. i am somewhat new to VB programing so any pointers would be greatly appericted.

I have a datagrid with a checkbox in it, when the checkbox is checked it writes its value to a hidden control (via javascript). There is multiple pages in this datagrid, and when I go to page two, then back to page one, my checkbox's are not checked and the hidden control is not populated either.
Anyone know a trick to keep the checkbox's selected as well as the hidden textbox populated with each checkbox's id?
This is VS2003 and VB.Net

You'll have better luck asking this in the ASP.NET Forum.

Somehow a Windows application is closing when trying to dispose of the calling form using me.dispose.
If .. = True Then
Dim SelectFiles As New frmSelectClearingFiles
SelectFiles.Show()
Me.Dispose()
Else
..
Any ideas?

Please tell me this code isn't on your startup form!
If you close, or dispose, the startup form, you're entire application dies. The startup form has the applications message pump attached to it. If that goes away, so does your app.

I'm in need of being able to create MS Word documents and edit them from VB 6.0. I know that this can be done via VB .NET and also C#; but I'm wondering if all of the calls the VB .NET and C# make to Word are also available in VB 6.0? Thanx!

Yes.
All of the calls that VB.Net and C# can make via the Interop are also available in VB6.0 by referencing the MSWord.olb file in your project.
I suggest you get an MS Office Word Language Reference book to find out the object model and functions available.

Yes all the calls are available
Check this
Dim MyPath as string = "c:\test\"
Set ObjWordKit = CreateObject("Word.Application")
With ObjWordKit
.Visible = True
.Documents.Add (MyPath & "yourtest.dot")
.activedocument.Bookmarks("MyText").Select
.Selection.Text = "set into word text"
end with
if you need other functions from Word, make a Word-macro and just copy the code and you are close.
Hope this helps

I was wondering if anyone knows of a way to call a C# program from Visual Basic 6.0. I currently have a VB 6.0 application and I'd rather not have to go through the pain in upgrading it to VB .NET but I need to enhance it to call some C# code. Does anyone know if this is even possible in VB 6.0? Thanx!

You can enable COM-Interop registration in the properties of the assembly. You can then use it like any other COM library.
