Listbox mouse XZ not working properly

[David RH]

Hello

I upgraded a VB6 app to .net.

I'm in the process of removing all of the VB namespace stuff to get the app to pure .net.

I have a listbox that allows you to select multiple lines. In the mouse up event the upgrade wizard created these lines:

Dim Button As Short = eventArgs.Button \ &H100000
Dim Shift As Short = System.Windows.Forms.Control.ModifierKeys \ &H10000
Dim x As Single = VB6.PixelsToTwipsX(eventArgs.X)
Dim y As Single = VB6.PixelsToTwipsY(eventArgs.Y)

If I change it to this:

Dim Button As Short = eventArgs.Button \ &H100000
Dim Shift As Short = System.Windows.Forms.Control.ModifierKeys \ &H10000
Dim x As Single = eventArgs.X
Dim y As Single = eventArgs.Y

to remove the VB6 reference the mouse coordinates are not right and it messes everything up.

I've looked around to see of I can find some setting to fix it but I can't see anything that looks like it will help.

Any Ideas?

Thanks

David

Ps: 1 pixel = 15 Twips

Get rid of those twips! , what are you trying to do with the mouse coordinates that's not working?

I'm trying

I already converted all of the other T to P stuff (control position coordinates and such) and that went well.

The mouse doesn't return the correct coordinates so the wrong item gets selected.

I recommend coding from scratch instead of using .net's migrator or you may end up with quite a pile of ****

.NET code works in pixels all the time. If you change the code that uses those 'x' and 'y' variables to use pixels too then there's no issue.

Now I'm really flummoxed.

The problem started when I messed with those 2 lines. But I did a search and they don't appear to be used anywhere. So I put them back to their previous state and the problem didn't go away. ???

The line of code that it chokes on is:

If lstSortedLines.SelectedIndex < 7 Then

The error code is:

An unhandled exception of type 'System.IndexOutOfRangeException' occurred in system.windows.forms.dll

Additional information: Index was outside the bounds of the array.

Ideas?

Say is it possible to have a multi-line item in a listbox?

Example: each list item has a 3 line paragraph of text completely visable.
