通过我对 MaxTo 的自动崩溃收集我收到以下崩溃报告:
V8.12.0.0 - System.ComponentModel.Win32Exception - :Void UpdateLayered():0

另一个堆栈跟踪:

在这个最新的堆栈跟踪中,根本没有引用 MaxTo,我遇到的 90% 的崩溃都是与上述类似的堆栈跟踪。
在网上四处阅读,我发现如果您忘记释放或处置变量,这个错误很常见。在查看我的 WndProc
时,似乎有时会出现问题,但我找不到一个地方卡在对任何对象的引用上。除了一个变量外,所有变量都是 WndProc 的本地变量,因此应该在方法终止时进行垃圾回收。
protected override void WndProc(ref Message m)
{
base.WndProc(ref m); // I'm assuming the first trace can be caught here
IntPtr hwnd = m.WParam;
// Our hook tells us something got maximized
if (Win32Import.UWM_MAXIMIZE == (UInt32)m.Msg)
{
// Figure out if we are temporarily disabled or using alternative profiles
KeyStateInfo keyState = KeyboardInfo.GetKeyState(Settings.AlternativeProfileKey);
Rectangle r = FindRectangle(MousePosition, (Settings.EnableAlternativeProfile && keyState.IsPressed ? AlternativeRegions : Regions));
// Did we find a rectangle to place it in?
if (r != Rectangle.Empty)
{
Rectangle position = Win32Import.GetWindowRectangle(hwnd);
Rectangle previousPos = GetLocation(hwnd);
if (position == r && previousPos != Rectangle.Empty)
{
// We are restoring the original position
Win32Import.SetWindowPos(hwnd, IntPtr.Zero, previousPos.X, previousPos.Y, previousPos.Width, previousPos.Height, Win32Import.SWP_NOZORDER | Win32Import.SWP_NOSENDCHANGING);
}
else
{
// We are maximizing to a region
Win32Import.ShowWindow(hwnd, Win32Import.WindowShowStyle.Restore);
Win32Import.SetWindowPos(hwnd, IntPtr.Zero, r.X, r.Y, r.Width, r.Height, Win32Import.SWP_NOZORDER | Win32Import.SWP_NOSENDCHANGING);
// Make sure we remember this location
RememberLocation(hwnd, position);
}
}
}
else if (MaxTo64WindowHandleMessage == m.Msg)
{
// Store the window handle of our 64-bit subprocess
SubProcess64WindowHandle = m.WParam;
}
}
我无法重现错误,即使在多天运行该程序也是如此。
我的假设是系统的未碎片化内存或 GDI 句柄不足,但我无法在任何地方证实这一点。似乎没有关于此错误的任何好的文档。
还有什么想法吗?我可以做些什么来防止这个错误吗?
更新:由于缺乏合适的解决方案,该问题已重新打开并提供更多堆栈跟踪。简单地忽略它并不能解决问题。
最佳答案
泄漏或使用许多 GDI 对象/句柄。这些可能会导致资源堆短缺。您可能无法重现,因为您的用户可能正在运行其他 GDI 资源繁重的程序或使用终端服务器,在这种情况下,他们必须与其他用户共享一些堆。参见 System Error. Code: 8. Not enough storage is available to process this command
