Sample Code:
/// <summary>
/// Gets the handle to the horizontal scroll bar.
/// </summary>
/// <param name="parentControl">The parent window of the scrollbar.</param>
/// <returns>Handle to the scrollbar window.</returns>
private IntPtr GetHandleToHorizontalScrollBar(Control parent)
{
// Locals
IntPtr childHandle;
string appDomainHexedHash;
// Get the hexadecimal value of AppDomain hash code.
// This value is dynamically appended to the window class name of the child window
// for .NET Windows Forms. This name is viewable via the Spy++ tool.
appDomainHexedHash = AppDomain.CurrentDomain.GetHashCode().ToString("x");
// Find window handle
childHandle = FindWindowEx(
parent.Handle, // Parent handle
IntPtr.Zero, // Child window after which to seek
"WindowsForms10.SCROLLBAR.app.0." + appDomainHexedHash, // Class name to seek (viewable in the Spy++ tool)
IntPtr.Zero); // Window title to seek
Here is an alternative Managed API to FindWindow, The article also describes a way to CloseWindow of another process like notepad, not sure if there is such thing in Win32 API, but at least you can do it in .NET! Here is the article:
helpful tips or sample code to share for using this API in managed code?
corrections to the existing content?
variations of the signature you want to share?
additional languages you want to include?
Select "Edit This Page" on the right hand toolbar and edit it! Or add new pages containing supporting types needed for this API (structures, delegates, and more).
