View 1 RepliesI am creating some help files by using a TabContol box, on one of the tabs I need to have the scroll bars to be able to scroll down to see all the info.In nearly all software packages that I know of, you can also use your mouses' scroll wheel to move the scroll bars. This is not happening for me in this particular situation. I have looked for a setting in the TabControls properties settings, but cannot find anything to enable the mouse to move the scroll bars.

I tried making the form as large as the picture box (which is 3840 x 2160) and then just move the form sideways by clicking and dragging on the control box, but the form will not go larger than 1940 x 1100. Can I put scroll bars on this picture box, or is there another technique I should use?
View 2 RepliesIs there a way, in VB.NET, to output the current line number in the source code? For example:
Try
' The following line will purposly cause an error
Dim BigNum As Int64
[code].....
For example, this:
var Data = new Array(new Array("ASDFGG", "asd_10377142_keyword", 9, 42285017, 10377142, 1), new Array(""ASDFGP", "asd_10377149_keyword",", 9, 42284844, 10377163, 1)... and so on
As you can see, I only need the digits right before the _keyword
I want this action to be on the button click.
