Basic controlcommand problems

[cag8f 0]

I'm slowly learning the control functions in Autoit. I can get this line to work succesfully:

ControlCommand("WINDOW1", "", "WindowsForms10.COMBOBOX.app.X.XXXXXXXX" , "ShowDropDown", "")

The combo box in question drops down and reveals its options. However when I try the same line, only with the GetCurrentSelection command inserted:

ControlCommand("WINDOW1", "", "WindowsForms10.COMBOBOX.app.X.XXXXXXXX" , "GetCurrentSelection", "")

nothing is returned. The combo box definitely has a current selection displayed (i.e. the selection is not blank). What am I doing wrong? Thanks in advance.

Try with SetCurrentSelection instead of GetCurrentSelection.

[Zedna 200]

ControlCommand works only with standard Windows controls.

ClassName WindowsForms10.COMBOBOX.app.X.XXXXXXXX is probably nonstandard one.

This may be a non-standard Windows control. But if so, why does controlcommand work with the "ShowDropDown" command? Or will non-standard controls behave that way: work fine for some commands but not for others?

And SetCurrentSelection is my ultimate goal for this control. However that does not work either. As a diagnostic, I was trying to figure out why a simple control command (GetCurrentSelection) was not working, then move on to SetCurrentSelection.

you need to use combobox and listbox UDFs

example tested with WindowsForms controls

I would also look at @error and do testing with ControlGetHandle.

You need to understand why the control is not being found.

I agree I need to understand why the control is not being found. I will play with this and return results, thanks.

help file remarks for ControlCommand()

"Certain commands that work on normal Combo and ListBoxes do not work on "ComboLBox" controls."

the WindowsForms10.COMBOBOX .NET managed control has a ComboLBox listbox class

the Combobox/listbox udfs work, as shown in my code example above.

the code was tested with Putty Connection Manager, a .NET application.

OK that is very illuminating. I did not know how to find out what type of control mine was. I haven't had a chance to experiment with the UDF(s) you posted. I will do so soon and get back to you. Thanks for your help.
