unmanaged

I have a simple application that loads an unmanaged dll and passes a few string values to it from C#. But in the C++ dll application, I receive an exception :: Tried to access a read/write protected memory. My DLL Import looks like this: [DllImport("X.dll", CallingConvention = CallingConvention.Cdecl) ] public static extern int DumpToDBLogFile([MarshalAs(UnmanagedType.I4)]int loggingLevel, [MarshalAs(UnmanagedType.I4)]int jobId, int threadId, [MarshalAs(UnmanagedType.LPStr)]string procName, [MarshalAs(UnmanagedType.LPStr)]string message); and the C++ Declaration is like extern "C" __declspec

I'm trying to access an unmanaged library and am lucky to have access to a comprehensive guide to the API. Unfortunately, I've no idea what the C# equivalent of C++'s WORD type is. Similarly, I've no idea what DWORD would be. yan You're probably looking for ushort for WORD and uint for DWORD. 来源： https://stackoverflow.com/questions/5490428/whats-the-equivalent-of-word-in-c

I have been able to successfully wrap my unmanaged Borland C++ dll, and launch it's forms from a C# .NET 4.0 application. Is it possible to embed a form from the dll directly into a .NET application? To clarify, the original form is being used as an embedded control in a Borland C++ project already. It essentially looks like a custom control, sitting on a panel within the application. When I say 'embed' I mean place INTO a form in the same way you drop buttons, panels, etc on to a form. I'm not looking to just make a child form. If this is not possible, then perhaps a better question would be

I thought that a delegate instance was interchangeable with a function instance. Take the following code: delegate int AddDelegate(int a, int b); AddDelegate DelegateInstance; public void DoStuff() { //I can call this without a delegate "instance": MethodThatTakesAdd(Add); //I can also call it WITH a delegate "instance" DelegateInstance = Add; MethodThatTakesAdd(DelegateInstance); } public int Add(int a, int b) { return a + b; } public void MethodThatTakesAdd(AddDelegate addFunction) { Console.WriteLine(addFunction(1, 2).ToString()); } Both ways of calling it APPEAR to be equivalent, and if

I am trying to create a Nuget package for a library that depends on ghostscript and therefore references gsdll32.dll - an unmanaged library. I can't just included that a standard dll reference. Where do I put this in the nuget directory structure? Add a build folder to the package and, if the package for example has the id MyPackage , add a MSBuild target file called MyPackage.targets to this folder. It is important that the .targets file has the same name as the .nuspec file. In the .nuspec file you must have a section like this: <files> <file src="lib\*.*" target="lib" /> <file src="build

In C#, I defined a struct: [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)] public struct MyObject { [MarshalAs(UnmanagedType.LPWStr)] public string var1; [MarshalAs(UnmanagedType.LPWStr)] public string var2; }; I have this struct in C++: public value struct MyObject { LPWSTR var1; LPWSTR var2; }; And in the method of C++ which is a public class to be called from C#: TestingObject(MyObject^ configObject) { // convert configObject from managed to unmanaged. } The object is debugged correctly that I can see two strings var1 and var2. However, the problem now is that I need to
