Making a picture change RANDOMLY IN A GUI

[ryanjordan]

The code below, changes a picture RANDOMLY every 5 seconds.
The problem is that every time this happens A NEW GUI is generated with a new picture.

Please help me to understand how the GUI will stay the same and NOT re-generate and INSTEAD just the
picture changes.

Help is greatly appreciated. Thank you in advance!!

Use GuiControl to update an existing control.

What I would do is first create your GUI. Then enter in a loop to use just the GuiControl command and the Sleep 5000. Or, slightly preferably, SetTimer on a 5 second intersection.

Hello Exaskryz, I have being playing with this for awhile. Just getting various errors.

Is it possible that you could show me a SMALL EXAMPLE so I can compare my mishaps with your small sample.

I do understand if your are tooo busy.

Thank you for the post.

Cheers

One thing I forgot in the loop is you'd want to repeat your Random command too.

Code: Select all

Gui, Russ:Add, Picture, vPic, Tulips.jpg
Gui, Russ:Show
Sleep 2000
GuiControl, Russ:, Pic, Roses.jpg

You'll notice that I put a "blank" command in the first parameter of GuiControl. I still put the name prefix and the colon to specify which GUI I was working on (unnecessary if Russ is the default GUI, however, I have a habit of including my names always). Also notice that I used the name of the variable in the second parameter of GuiControl.

Btw the #persistent directive is unecessary in your script:

Any script that uses the GUI command anywhere is automatically persistent (even if the GUI command is never actually executed).

source: GUI

Once a script has at least one hotkey, it becomes persistent, meaning that ExitApp rather than Exit should be used to terminate it.
