Combo Box error

[Aiakonai]

This line

Dim $comboText = _GUICtrlComboBox_GetEditText($RC_mainUserListBox)

this is just one line in much larger program. the problem I'm having is not syntax but compatibility.

works fine in windows xp, but if you try to run it on a win2k machine it returns a character the looks like

a solid block ... something like the letter l right next to the lettere l without a space in between. The data actually

in the edit portion of that control was the letter "a". On the winxp machine it grabs that information correctly from the box.

On the win2k machine it simply returns a double l looking block (kinda looks like a null character).

can anyone offer a solution / alternative to this kind of gui... I really want something that autocompletes... and actually

works on a win2k machine .. and a winxp machine. Thank you for any help on this matter

In case anyone actually wanted to see the code for the entire program ... here it is.
