[RESOLVED]Sendmessage radio button click

[TTn]

I've looked around here, and found some examples, but still cant get this API to click a radio button. This is stupid, it must be me.


Is this how the API should be called?

lhWndParent = exe.MainWindowHandle.ToInt32
lhWndButton = FindWindowEx(lhWndParent, 0, "Button", "&Continue sieving an old file")
 
SendMessage(lhWndButton, WM_COMMAND, 0, 0)
 
'or 
 
SendMessage(lhWndParent, WM_COMMAND, lhWndButton, 0)

I've tried several variations, and wonder if it's a problem with the recieving application... or me.

It must be the first one, because the last 2 parameters are message-specific info.

What errors are you getting?? And make sure that you are getting the handle of the desired radio button.

I'm not getting any errors directly, but it isn't clicking the button.

The handle should be right(findwindowex), since I can disable the button via that handle. I used SPY++ to find the Button's caption, and class name "Button". It's not working on a regular button either.

The program in question, can be found here:

I want to click the start/stop button, and the radio check button, for new/old file.


[EDIT]
I've edited the first post, to show the button's caption.

I guess two lines will have to do for now:

SendMessage(lhWndOldButton, WM_KEYDOWN, VK_SPACE, 0)
            SendMessage(lhWndOldButton, WM_KEYUP, VK_SPACE, 0)

This seems to work for the regular button too. duh
