Hi.

I'm working on a script that displays an icon based on a path to a file specified by the user. In most cases the specified files are .exe files and contains an .ico file which is then used as a picture. But sometimes the specified file does not have a useable image file, and it just looks stupid without any picture. That is why i am trying to figure out a way to check whether a file contains a useable image file or not, so that if the specified file does not contain an image file i could just use some other predetermined icon.

Any ideas on how to check if a given path contains a useable picture for Gui, add, picture?

check for the width and if 0 use default ico ?

Code:

Gui, Add, Picture, Icon hwndpic vmypic, C:\my.exe
ControlGetPos, ,,width,height,,ahk_id%pic%
if width=0
GuiControl,,mypic,  c:\icos\default.ico

A nice idea, but that does not quite work, since i use the following code:

Code:

Gui, 1:Add, Picture, x%iconx% y%icony% w25 h25 icon1 AltSubmit BackgroundTrans hwndpic vmypic, %whichicon% 
ControlGetPos,,, iconwidth,,,ahk_id%pic%
msgbox %iconwidth%
if iconwidth = 0
Guicontrol,, mypic, key21.ico 

The h25 is preset to make sure its the right size, so its width is still 25 even if there is no picture displayed. Also it seems to display the start of the path that was used... Thanks for your idea though
