sure it does. but it is into the Microsoft.VisualBasic Namespace (assuming you're working on VB.NET).

MSDN tells

Public Shared Function Left( _
   ByVal Str As String, _
   ByVal Length As Integer _
) As String

is this[^] satisfy you better now ?? Suspicious | :suss:

Problem in C1FlexGrid Drag and Drop

Hi,

We are developing a Windows Explorer type application in VB.Net. We are using a TreeView Control and C1FlexGrid (Component One Flex Grid for VB.Net).

We want to provide the Drag and Drop functionallity from C1FlexGrid to TreeView.

The problem is that we are not able to drag multiple non-continuous rows from C1FlexGrid to TreeView. User can use CTRL key to select multiple non-continuous rows.

regards,
Deepak Kamboj

Your best bet would be to ask Component One about this. Since there are thousands of libraries and components around, we can't possibly support them.

Debugging in VB.Net

I wonder if anyone can help me.

In VB6, when you ran a project and put a break point in, you could pause (break) the code and do some tests, even input new values. In .Net I cannot get this working. I have to end the project.

Also when you put a bookmark on the code, I cannot get this working. What I mean is if I put a bookmark in one module and another one in a say a form, it does not go to the next bookmark. I have to open the form or module then do the process.

Any ideas what I am doing wrong.

Well for changing values you can select the variable which you need to change the value during testing and press Ctrl + ALT + Q
now here nto only you can see the current value but also you can change the value in the grid and value is changed for testing purpose.

and be sure that you are in debug mode not in release mode while testing the application.

Why, on this earth, would you combine handlers for two completely different events on two completely different controls into one handler?????

If you want to run common code for both of these events and have to differentiate between the two, the easiest way is to NOT combine them into one handler! Seperate the handlers so that each handles it's own control and event. Then in your event handlers code, without using any code at all!, you can easily determine which control fired the event. You can then call the common code, in it's own sub or function, passing any parameters that your code needs.

Now, if you really want to make your code unreadable, you could keep the event handlers combined (lucky you, they use the same signature). Just check the object type of "sender" in your handler code.

Private Sub CombinedHandler(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click, TextBox1.MouseEnter
    If sender.GetType().Equals(GetType(Button)) Then
        ' Button was clicked...
    Else
        ' TextBox was entered...
    End If
End Sub

Intellisense will show you all the properties of a member.

In this case, I found it by whipping up a project and looking through the properties.

comboBox.DroppedDown = true

will drop the combo. I assume you know how to make it visible. Invisible/visible ui components often suck, you should disable it instead, so it's visible but grey.

Yeah, I thought of that after I replied. I'm sorry, I never use VB, my background is in programming. You really should specify VB6, because they are really different languages, and I think most people would assume VB.NET. It's my opinion that it would make sense for the two to be split into different forums, as C++ and managed C++ are.

Windows UserControl in Web Page.

Hi,

I know this is probably easy but...

I created a Windows UserControl in VB.Net and added a ComClass interface to enable me to host it in a classic Web Page and for that page to receive an event raised by the control. This works fine on my machine.

I placed the Control and the Web Page to IIS on a new server and now I get the control but the event has gone.

Any Ideas please ??

Thanks

I love these 'it doesn't work' questions. What does it do wrong ? Have you contacted the people who wrote your PDF library ? Have you looked at their samples ?
