• Marcus Widerberg ComboBox Frustration: Setting a default "SelectedIndex" when adding a new record refuses to work.

  Help! This is a very frustrating problem. Ok I have a typical databound Form with a bound ComboBox bound on the form Load event. I have a typical BindingSource and BindingNavigator Control with an "AddNew" button. When a new record is added to the dataentry form (i.e. not the combobox) I intend the combobox to default to the first value in the list by setting... mycombo.selectedindex = 0 I have this in the BindingNavigatorAddNewItem_Click event but it has no effect! I also tried placing mycombo.selectedindex = 0 in the BindingSource "AddingNew" event but this also has no effect. I have discovered that the "selectedindex" is somehow inexplicably changing itself back to  -1 As an experime ...Show All

• Mar_GP VB6 interop to .NET webservice client

  I have generated a C# client .dll for a .NET webservice. I did this by adding a web reference in VS and edited the .cs file. I have added interfaces and attributes for COM interop. I have it registered on a Win2k machine and cannot access it with VB6. Of course VB6 Intellisense works fine (I'm assuming due to the interfaces). When I run the app, it pukes with 'ActiveX component can't create object'. I understand this to indicate a registry problem, but I've done many REGASM's and GACUTIL's. I have seen many examples of VB6 to webservices, but they all use the MSSOAP3.0 toolkit. I have successfully accessed the webservice with the MSSOAP3.0 toolkit. Is it even possible to hack a VS generated webservice client .dll, and has anyone got an ...Show All

• kperson Scrolling Treeviews and DataGridView together

  I have Treeviews and DataGridView side by side, and I would like to scroll these controls together. So if the user scrolls down one Treeviews or DataGridView, the other would scroll automatically. How should I do this in VB .NET 2005 I would keep the index of the first displayed row/node the same (or whatever index matches) in both controls. I don't know the DataGridView control too well, but I think it's these: TreeView.TopNode.Index DataGridView.FirstDisplayedScrollingRowIndex ...Show All

• Leo Kent Button1_KeyUp

  Why it doesn't work when I quite hold of button1 Private Sub Button1_KeyUp( ByVal sender As Object , ByVal e As System.Windows.Forms.KeyEventArgs) Handles Button1.KeyUp MsgBox( "Button1 is up" ) End Sub Thanks Thank you, DMan1 .

• ArchanaG Select Case statement being evil

  The select case statement is out to get me! Has anyone else run into the trouble of having a Select Case statement and one of the case statements has hit if you look at the data, but refuses to hit anyway That probably doesn't make sense... Put it this way... I have, say, a ListBox control that has three IP addresses in it. For argument's sake we'll say the three items are: 192.168.0.1 192.168.0.2 192.168.0.3 These items have the indices 0, 1 and 2 respectively. Now, inside a function that receives a string of data (T) from a network user I have code that's something like this: Dim X As Integer For X = 0 To (ListBox1.Items.Count - 1) Select Case ListBox1.Items(X) Case T 'Code segment 1 Case Else 'Code ...Show All

• Kevin Stephens Crystal Reports in VS 2005

  We are using VStudio 2005 Professional at work and it comes with a version of Crystal Reports. Does anyone know if this version of CR is a sample or is it a full version Thanks. Oh, I didn't get that from your original post. I'm not sure, but I don't think that has anything to do with versions. It sounds like you've got some empty properties on your report and you'd like to hide them. If that's the case, you can conditionally suppress fields or do some text formatting to "pretty print". It's a full version in that you can deploy reports freely withouth having to worry about licensing. I'm not 100% sure, but in earlier version ...Show All

• Tryst wrong Count of Records

  Hi, I am having troubles with the count of records in a Form. All my Tables used in my Access database are linked tables to an SqlServer. The Form I use is a wizzard created form and the recordsource is simple like "SELECT * FROM tab1 join tab2 ..". I want to display the number of records in the form, but it seems, that the recordset does not load all records at once. What i did is: Private Sub Form_Current() lblRecordCount.Caption = Recordset.RecordCount End Sub But when I open the form, it displays just "16", if i move to a record below, it changes to "28", when i scroll to the end it finally displays "100" - which is really the right count. I tried this also with a new database, where i created a table with 500 records ...Show All
