pinvoke

问题 In my .Net assemblies I would have to make use of some native (C++ ) dlls. Usually we need to copy the C++ dlls into the bin folder and use PInvoke to call it. To save the distribution cost, I want to embed the C++ into my .Net dll direct, so that the number of assemblies distributed would be less. Any idea how to do this? 回答1: You would embed your native DLLs as resources. Then at runtime, you would have to extract those native DLLs into a temporary folder; you don't necessarily have write

问题 I am trying to load a Winamp input plugin and work with it in C#. According to the Winamp SDK, this is the proper way to load a plugin: in_mp3_lib = LoadLibraryW(path); if (in_mp3_lib) { PluginGetter pluginGetter = (PluginGetter)GetProcAddress(in_mp3_lib, "winampGetInModule2"); if (pluginGetter) { in_mp3 = pluginGetter(); } } So I've created a similar code in C#: [DllImport("kernel32", SetLastError=true, CharSet=CharSet.Unicode)] static extern IntPtr LoadLibrary(string lpFileName); [DllImport

问题 I currently have a program written in c# invoking CredRead/CredWrite from Advapi32.dll to make it easy for users that are not joined to the domain to save terminal server/WebDAV server credentials. (http://msdn.microsoft.com/en-us/library/aa374788%28v=vs.85%29.aspx for credential structure information) This is all working fine, but I ran into an issue the other day that persists on all XP operating systems; I cannot save the terminal server credentials. The native CredWrite method is

问题 The following is a bit of C++ that is verified working: typedef struct { PVOID buffer; UINT32 length; } DATA_BUFFER; typedef struct { DATA_BUFFER TxBuf [1]; DATA_BUFFER RxBuf [1]; } JVM_COMM_BUFFER; UINT32 SendAndRecv( IN JHI_HANDLE handle, IN CHAR* AppId, INOUT JVM_COMM_BUFFER* pComm ); The following is my attempt to port that to C#: [StructLayout(LayoutKind.Sequential)] public struct DATA_BUFFER { public byte[] buffer; public uint length; } [StructLayout(LayoutKind.Sequential)] public

问题 Here is how I change the TimeZoneInfo (App #1) : private static void ChangeTimeZone(TimeZoneInfo tzi) { TIME_ZONE_INFORMATION actual = new TIME_ZONE_INFORMATION(); NativeMethods.GetTimeZoneInformation(out actual); if (tzi == null || actual.StandardName == tzi.StandardName) return; TIME_ZONE_INFORMATION newZone = (TIME_ZONE_INFORMATION)tzi; RunWin32Method(() => NativeMethods.SetTimeZoneInformation(ref newZone)); // Update .NET CultureInfo.CurrentCulture.ClearCachedData(); TimeZoneInfo

问题 I am looking to create a C# program that calls a managed C++ dll, which then executes functionality in a native C++ dll. As part of this call, I want to provide a C# callback function that could be invoked by the native C++ dll. The C# code would call some managed C++ code, which would call the following native C++ code; I want the native C++ code to call my C# callback cb : int dobatch(CString str) { // I want to to call c# if (cb) return(cb(str)); // this would execute the function passed

问题 Trying to access an old c++ dll from c# using Dll Import. Been searching around the net for aprox 4 days now without success. I'm trying to use the c++ dll from an asp.net mvc 3 website .net 4.
