c# – Win32Exception没有足够的存储可用于处理此命令

通过我的 MaxTo的自动化崩溃收集我得到以下崩溃报告: V8.12.0.0 – System.ComponentModel.Win32Exception – :Void UpdateLayered():0Version: MaxTo8.12.0.0Exception: System.ComponentModel.Win32ExceptionError message: Not enough storage is available to process this commandStack trace: at System.Windows.Forms.Form.UpdateLayered() at System.Windows.Forms.Form.OnHandleCreated(EventArgs e) at System.Windows.Forms.Control.WmCreate(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WmCreate(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at MaxTo.MainForm.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd,Int32 msg,IntPtr wparam,IntPtr lparam)

另一个堆栈跟踪:

Version: MaxTo2009.9.0.0Exception: System.ComponentModel.Win32ExceptionError message: Not enough storage is available to process this commandStack trace: at System.Windows.Forms.Form.UpdateLayered() at System.Windows.Forms.Form.OnHandleCreated(EventArgs e) at System.Windows.Forms.Control.WmCreate(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WmCreate(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd,IntPtr lparam)

在这个最新的堆栈跟踪中,根本没有引用MaxTo,90%的崩溃是与上述类似的堆栈跟踪.

在网上阅读我发现如果你忘记释放或者处理变量,这个错误是平常的.当我看到我的WndProc,似乎有时候有问题通过,我找不到一个地方挂在任何对象的引用.除了一个变量之外,所有变量都是WndProc的本地变量,因此在方法终止时应该是垃圾回收.

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,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; }}

即使在多天内运行程序,我也无法重现错误.

我的假设是系统在未分片的内存或GDI句柄上都很低,但是我无法在任何地方确认.这个错误似乎没有任何好的文档.

有什么想法还可以吗?我可以做任何事情来防止这个错误吗?

更新:由于缺乏一个体面的解决方案,该问题重新打开了更多的堆栈跟踪.简单地忽略它并不能解决问题.

解决方法 泄漏或使用许多GDI对象/句柄.那些可能导致资源堆不足.您可能无法再现,因为您的用户可能会运行其他GDI资源重型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.见 System Error. Code: 8. Not enough storage is available to process this command
