Using a control for SendInput on a custom form ? (will pay)

[aggsyb]

Ok this is so beyond frustrating that I will even be willing to pay someone to help me via skype....

I am using visual studio c++, I know this is a custom button and not a Windows button so probably cant just use the standard API to "click" it , but surely there has to be something very similar or a workaround for it?

I have a form , parent form I want to be able to sendinput to a button on that that form. However spy++ shows it has no control ID but it grabs the caption. I tried Enumchildproc which came back with nothing so I really am lost , this button being pressed without the mouse / keyboard being affected is absoloutley key to my program, so this is urgent. As I said before willing to pay if I really have too :\, included spy ++ screenshot and a screenshot of the control.

ANY suggestions are more than welcome ,

Up, still need this one. Badly!

This is a Win32 project?

What do you mean by its being a 'custom button'?

[aggsyb]

Atm I am just running it in console but the form itself is custom and the button itself is a "pokerstars button class" instead of being a "windows button" which can easily be controlled by API , I am in a little over my head with this one which is why I am willing to pay for help if it is required. I need the button pressed as if it was a "windows button" being pressed by the API.

Hope that makes sense?

Ben.

Doesn't make much sense to me, unfortunately. I'd help for free if I was sure of what you are doing, and what you need to know is something I indeed know myself. If all you need to know is how to send a button a message to simulate a click, look up the BM_CLICK message, and the BN_CLICKED message.

I really don't know what a 'pokerstars' button is. And I'm not entirely sure if you are doing console mode programming or GUI programming. Its also possible to be doing GUI programming, but have a console window too.
