我的问题是如何在WPF应用程序中运行应用程序(.exe)。我的意思是在此代码记事本中运行在应用程序窗口内部运行,而不是在外部运行应用程序,但如果在exte中打开更改.exe文件(例如calc.exe)应用程序
private Process _process;
[DllImport("user32.dll")]
private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
[DllImport("user32.dll", SetLastError = true)]
private static extern int GetWindowLong(IntPtr hWnd, int nIndex);
[DllImport("user32")]
private static extern IntPtr SetParent(IntPtr hWnd, IntPtr hWndParent);
[DllImport("user32")]
private static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, int uFlags);
private const int SWP_NOZORDER = 0x0004;
private const int SWP_NOACTIVATE = 0x0010;
private const int GWL_STYLE = -16;
private const int WS_CAPTION = 0x00C00000;
private const int WS_THICKFRAME = 0x00040000;
private void LaunchChildProcess()
{
_process = Process.Start("notepad.exe");
_process.WaitForInputIdle();
var helper = new WindowInteropHelper(this);
while(_process.MainWindowHandle == IntPtr.Zero)
{
System.Threading.Thread.Sleep(10);
_process.Refresh();
}
SetParent(_process.MainWindowHandle, helper.Handle);
// remove control box
int style = GetWindowLong(_process.MainWindowHandle, GWL_STYLE);
style = style & ~WS_CAPTION & ~WS_THICKFRAME;
SetWindowLong(_process.MainWindowHandle, GWL_STYLE, style);
// resize embedded application & refresh
ResizeEmbeddedApp();
}
private void ResizeEmbeddedApp()
{
if (_process == null)
return;
SetWindowPos(_process.MainWindowHandle, IntPtr.Zero, 0, 0, (int)ActualWidth, (int)ActualHeight, SWP_NOZORDER | SWP_NOACTIVATE);
}
protected override Size MeasureOverride(Size availableSize)
{
Size size = base.MeasureOverride(availableSize);
ResizeEmbeddedApp();
return size;
}
答案 0 :(得分:1)
通常,您不能。如您所见,只有一小部分Win32应用程序支持窗口重定影。
您确实有一些选择:
DwmRegisterThumbnail
来获取目标窗口表面的实时副本,这些窗口显示为应用程序顶部的覆盖图。
DwmSetIconicThumbnail
-除了它允许您在内存HBITMAP
中获取目标窗口之外。
HBITMAP
依赖于GDI,并且GDI不支持30位颜色(也就是10位颜色)之类的东西。 / li>
