How can I get the handle of a specific window using user32.dll?
Can someone give me a short example?
Try the following:
// For Windows Mobile, replace user32.dll with coredll.dll
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
// Find window by Caption only. Note you must pass IntPtr.Zero as the first parameter.
[DllImport("user32.dll", EntryPoint="FindWindow", SetLastError = true)]
static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName);
// You can also call FindWindow(default(string), lpWindowName) or FindWindow((string)null, lpWindowName)
You can use these declaration as follow
// Find window by Caption
public static IntPtr FindWindow(string windowName)
{
var hWnd = FindWindow(windowName, null);
return hWnd;
}
Here is a Concise version of the code:
public class WindowFinder
{
// For Windows Mobile, replace user32.dll with coredll.dll
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
public static IntPtr FindWindow(string caption)
{
return FindWindow(String.Empty, caption);
}
}
