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.

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
Chubby..

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 ?

will they give me the object name to be referenced?
|
|
|
|

Probably not, considering it's your code that is not creating the object. Have you stepped through your code, one line at a time and followed what it's actually doing? What line does the error show up on?

Hello there
the scenario is that I am fetching list of tables from database. and based on those tables I have to create a list of controls. like textboxes and labels to represent each data field. The form is dynamic with one combo box on top having all tables of Database in it.
now when user selects the other table it has to clear the list of controls and add a new set according to that selected table ( working fine upto now)
Problem ::: the size of panel is fixed and I have turned the auto scroll property to true. now when the table has more fields then scrollbar should come. but what is happening is if the big table is selected on the form load then it works fine. but once the form is loaded and then you change the table, then scroll bar does not appear and fields in last merge togather
any solution ????

HI Rizwan
From what i have understood you are adding controls to panel on a table select.If you are selecting this table from the dropdownlist.So you need to remove all previously added controls from the panel in the selectedindex event of the combobox
the code can be as follows
'where pnOutputs is the panel control
Dim NoControls As Integer = pnOutputs.Controls.Count
For i = 0 To NoControls - 1
pnOutputs.Controls.RemoveAt(0)
Next
once all the controls from the panel are removed u can add the new controls to the same panel control. I hope this is useful

well thanks for the code. some how i was doing the same thing. the problem is coming when the new controls are added and if they are more , Then the scroll bar does not come on the panel I dont know why ?
can you suggest any thing in this direction
thanks again for the code
|
|
|
|
|
well I was making achor =right for the newly added control. some how I removed it during testing and it started working fine. so if controls adding dynamically have anchor on it then scroll bar for parent control will not come..
cheers.......

Hye there
I wanted to change the color of Message box plus if possible wanted to change the text of buttons .
any comments ??
|
|
|
|
|
no way...
you have to make your own one if you want such behavior.
cheers,

As already stated the default message box wont do that (not without really hacking it  ). Have a look at this article for another one. Free definable buttons are already included and as you have the sourcecode its only a small step towards colored boxes.

c is the variable for my datagrid current row index. when c is gotten by the dataset it is shown in textboxes. if i edit this row how do i get the datagrid/ table to accept the changes to that row?

You can edit the row within the datagrid, or you can remember a primary key for the row, use it to do an UPDATE, and then rebind.
