I wrote a program which programmatically presses the "Install" button on a WebPlatformInstaller., but it doesn't find this button. Can you help me fix this code?

Windows: 00030590 Text: Install Class: WindowsForms10.BUTTON.app.0.378734a Style: 5601000B

This is my code:

Process[] processes = Process.GetProcessesByName("WebPlatformInstaller");

foreach (Process p in processes)// debug shows that there is 1 process
{
   IntPtr ButtonHandle = FindWindowEx(p.MainWindowHandle, IntPtr.Zero, "Install", null);
   SendMessage(ButtonHandle, BM_CLICK, IntPtr.Zero, IntPtr.Zero);

}

I'm not even going to ask why you want to auto-click the "Install" button of a setup... – Hanlet Escaño Jun 10 '14 at 17:32

Because I didn't find example, how programmatically install Azure Powershell via c#. – user3231442 Jun 10 '14 at 17:34
why shouldn't use SendKeys.Send(); ? – Saman Gholami Jun 10 '14 at 17:35
@SamanGholami Maybe it is just a separate process. – Hanlet Escaño Jun 10 '14 at 17:35
You could try the AutomationElement class. – Derek Jun 10 '14 at 17:36
Because it's console program, And when I tried send keys, the program throw exception. – user3231442 Jun 10 '14 at 17:36
For the SendKeys problem you could see my answer at: http://stackoverflow.com/questions/21934577/sendkeys-or-sendtextentry-to-a-game – Derek Jun 10 '14 at 17:38

SendKeys kinda sucks most of the time anyways. I prefer winapi myself for stuff like this. – Mike Cheel Jun 10 '14 at 17:38

Also, you are passing 'Install' as the class name parameter. I'm guessing 'Install' is the text of the button. If it was me I would be making friends with Spy++ right now and look at understanding the hierarchy of the app you are trying send messages to. Then investigate the use of GetWindow because FindWindowEx is not going to do it alone. – Mike Cheel Jun 10 '14 at 17:42
@MikeCheel just noticed that myself... looks like the issue. Should it be "WindowsForms10.BUTTON.app.0.378734a"? – geedubb Jun 10 '14 at 17:43
@geedubb Actually your advice didn't works. – user3231442 Jun 11 '14 at 15:18
