I tryed the code you posted and that aswell did not work.

They both  work perfect if you follow the instructions though.

eg: for the module, did you tried it out with an unpatched english MSN Messenger version 6.x while the main window was not minimized to the system tray, as stated in the first comment in that module and in my post? It will not work on Messenger 7 or whatever as the controls there are build up in another way (without windows)...

I made a test program called Notepad with a button called Test on it. I replaced the correct words in the code above (PROJECT and VIEW CODE) with NOTEPAD and TEST. Then I ran my test program then run the code above but still didn't work.

First of all, everything is made specifically for a certain situation; The code in the form doesn't work for everything.

Nevertheless, this time the blame was on my part. Though, you could've found where it went wrong if you'd understand what the code does (instead of simply copy/pasting).

Both lines with
GetWindowText CurHwnd, T, Length
must be
GetWindowText CurHwnd, T, Length + 1
and you should have replaced the obsolete GetWindowWord() API with GetWindowLong(), as stated in the comments...

I've done both edits in the source for you now... Sorry about the misleading.

The code shown is exactly what you want. Nobody can give you anything more specific if you aren't specific.

If you understand how the method works, you'll see that you can not make something general, working for everything in every situation as each situation is totally different. Even the code in Hitman Pro is specifically made for specific programs.

The big key here is to understand every line of code and understand what every API call exactly does. The MSDN Library can help you in that (http://www.msdn.com/).

To further help you and as asked in my previous post, be specific of what you want (and I mean really specific with all the small details and stuff)...

It worked this time. Thank you

What I'm trying to do is make a program that will automaticly update my computer when clicked. So like it will update norton antivirus and anti-spyware programs by its self. I makeing it for my Grand father since hes not the best on computers and often gets confused.

EDIT: I tryed that code with Norton System Works and MS Anti-Spyware and it finds the Window but cant find the button in the window to click.

First of all, Norton has his own auto-update features, check out the help files and manuals.

Second, even if you are able to press on a button, there are extremely many things which can go wrong and extremely many things which needs to be done first or after pressing the button.

I don't recommend making this for your grandfather (as good as the intention might be) as it will most likely produce more problems (not to mention crashes or whatever) which he can't solve at all. Instead teach him how to update such stuff for himself (or write it down or something)...


---------

For the problem itself, again I emphesize on understanding the code and understanding the methods used to find the button.

The button can be a child of another control which on his turn can be a child of another control which on his turn (...) etc (...), which on his turn is a child of the main window. You need to enumerate the complete tree. The Form code only looks at buttons directly placed on the main window. The Module code looks at buttons in all child windows and childs of those child windows.

Note that the term "window" is not the thing you think of as a window. A control like a button is also a window... Anything that has a window handle is called a window.

Note that not all programs work in the same way and not all programs have window controls which you could subclass or control (eg: MSN Messenger 7.x is a good example of this).

Ahh ok, I see what your saying. But because I want to learn this I still want to get it to work. Just for my own knoledge. Now your saying I should use EnumWindows() and EnumChildWindows() funtions right? Would they work the same as the GetWindow() and GetDesktopWindow()? Like for example:

CurHwnd = GetWindow(CurHwnd, GW_CHILD) < -- Original code.

CurHwnd = EnumWindows (CurHwnd, GW_CHILD) <-- Would that work?

nope... they are completely different. See the code in the Module for an example of EnumChildWindows()...

The enumuration functions use something which is called a "callback function" to work. The functions are called only once, and they in turn will call the function you provided as a parameter (hence the "callback") for each window they find.

For the complete detailed info about these API's (and any other API for that matter) see the msdn library and search for those API functions.

EnumWindows()
EnumChildWindows()

You should also never use the GetWindow() API for the purpose of enumerating/scrolling thru all the windows (hence the Form code isn't that good). Reasons for this can be read in the msdn library again.
