Split issue

[vixez]

I have this as code to run the program

Process.Start(ListBox1.SelectedItem.ToString.Split(New String() {"  "}, StringSplitOptions.None)(1))

Which used to work but then I added a "Preview image" function like this :

(ListBox1.SelectedItem.ToString.Split(New String() {"  Image:"}, StringSplitOptions.None)(1))

I now discovered that the first code is useless, because it selects everything after " " to run, including the "Image:"

This is how a listbox item is stored:

Tomb Raider Level Editor - Original  C:\Program Files\Tomb Raider - Level Editor\tomb4.exe  Image:C:\Program Files\Tomb Raider - Level Editor\load.bmp

As you can see it'll use this

C:\Program Files\Tomb Raider - Level Editor\tomb4.exe  Image:C:\Program Files\Tomb Raider - Level Editor\load.bmp

to run

Is there any way I can make it choose the path from " " and when it finds "image:" it stops?

MsgBox("executable:" & Environment.NewLine & ListBox1.SelectedItem.ToString.Split(New String() {"  "}, StringSplitOptions.None)(1))
MsgBox("preview image:" & Environment.NewLine & ListBox1.SelectedItem.ToString.Split(New String() {"  "}, StringSplitOptions.None)(2).Replace("Image:", ""))

If I use this :

Process.Start(ListBox1.SelectedItem.ToString.Split(New String() {"  "}, StringSplitOptions.None)(1))

It says Win32 exeption was unhandled ?

If I create a button and paste the code you provided, it shows fine in the message boxes tho.

how can I use Process.Start, or something else to start the program
(in the example I gave : C:\Program Files\Tomb Raider - Level Editor\tomb4.exe)

are you sure you've got the correct filename?

try running it directly:

Process.Start("C:\Program Files\Tomb Raider - Level Editor\tomb4.exe")

You want everything before "Image:" so just use IndexOf to find that position. You can then use Substring to get everything before that index. You can use Trim to remove the trailing whitespace and you've got your path.

That said, using a ListBox to store multiple values in one item is a hack anyway. A far better idea would be to use a ListView and store the executable path and image path in different columns.
