问题 I've not done any windows programming for a few years now and I'm a bit rusty on how to use dllimport. I have something along the lines of: extern "C" { __declspec(dllimport) int myFunct(); } int main() { cout<<myFunct(); } I get 2 unresolved externals linker errors and a warning that /DELAYLOAD:myLib.dll was ignored because no imports from it were found. What am I missing here? I thought that I can add the DLL to the delay load path, and the linker will figure to use it for the dll import??

问题 I have this code in .NET: result = NativeMethods.gsapi_init_with_args(_ghostScriptInstance, args.Length, _argumentPointersHandle.AddrOfPinnedObject()); That in its turn executes this code [DllImport("C:\\gsdll64.dll", EntryPoint = "gsapi_init_with_args")] public static extern int gsapi_init_with_args(IntPtr instance, int argc, IntPtr argv); The problem is that because of yet unknown problem the native execution enters into an infinite loop and never returns. The question is how can I cap the

问题 I would like to use IFileOperation in my .NET C# application. I found this article http://blogs.msdn.com/b/msdnmagazine/archive/2007/12/12/6738569.aspx (source code is available here http://download.microsoft.com/download/f/2/7/f279e71e-efb0-4155-873d-5554a0608523/NetMatters2007_12.exe).

问题 When using [DllImport("my.cool.library")] with .NET you get an error similar to the following: "Unable to load DLL... The specified module could not be found..." ...even though all the required DLLs are in place and clearly accessible!? 回答1: Turns out DLLImport only assumes the ".dll" extension if you do not have periods in the name. If DLLImport("my.cool.library.dll") was used, it would work, otherwise the DLL will have to be renamed to "my_cool_library.dll", and then DLLImport("my_cool

问题 Our solution was recently upgraded from .NET Framework v3.5 to v4.5.2 and as a result we have had some overflow errors running on Windows Server 2012 64-bit machines. These overflow errors seem to be coming from any instance where we call this function from the Windows API: [DllImport("user32.dll", CharSet=CharSet.Auto)] public static extern IntPtr SendMessage(IntPtr hWnd, int msg, int wParam, IntPtr lParam); The overflow was happening because for lParam in some instances, for whatever reason
