问题 I am making a program in C# to connect to a webcam and do some image manipulation with it. I have a working application that uses win32 api (avicap32.dll) to connect to the webcam and send messages to it that sends it to the clipboard. The problem is that, while accesible from paint, reading it from the program results in null pointers. This is the code I use to connect the webcam: mCapHwnd = capCreateCaptureWindowA(\"WebCap\", 0, 0, 0, 320, 240, 1024, 0); SendMessage(mCapHwnd, WM_CAP_CONNECT

阅读更多关于 CLIPBRD_E_CANT_OPEN error when setting the Clipboard from .NET

问题 Why does the following code sometimes causes an Exception with the contents \"CLIPBRD_E_CANT_OPEN\": Clipboard.SetText(str); This usually occurs the first time the Clipboard is used in the application and not after that. 回答1: Actually, I think this is the fault of the Win32 API. To set data in the clipboard, you have to open it first. Only one process can have the clipboard open at a time. So, when you check, if another process has the clipboard open for any reason , your attempt to open it
