I'm sorry if this is a dumb question, but I've been trying for hours with no luck , and maybe one of you can help. I have a class/library project I made in Visual Studio, a Spreadsheet in the SS namespace. Next, I created a windows form application, I then added the DLL, and put it in my resources menu, and it builds just fine, however...
This is probably a very stupid question. But assume that I have a DLL (test.dll), with some exports, that when built generates an import library (test.lib). I have an application TestApp that uses this DLL. Now, if I want to change some functions' implementation in the DLL, and I keep the exports unchaged, do I need to rebuild my applic...
Question: Is it possible to write a C# dll that can be pinvoked ? I want to write a replacement library for the WinAPI calls WritePrivateProfileString etc. for reading and writing ini files. Is it possible to export a function, e.g. 'WritePrivateProfileString', implemented in C# so one can pinvoke the dll with DllImport ? I want to re...
Hi , I am working on c sharp.I need to use an API exported from an unmanaged dll. The API in the dll is using Stringlist* as datatype for one argument. How can I define my DllImport in the C sharp project so that I can comfortably pass the equivalent data from c sharp to the unmanaged code. I tried using List, ArrayList, string[]. None...

With my C# application, I stole code from somewhere that looks like this: public struct LastInputInfo { public uint cbSize; public u...

Here's the setup: I've got a shared library (c++ with extern "C" methods) I've compiled in linux and created a library.so file. I've used Mono Develop on the same box (Ubuntu) and was able to DLLImport("library.so") and access my extern functions no problem. The problem comes in when I copied that .so file to a windows machine (Win7) ...
I have a DLL and I would like to use some of its functions. #include <iostream> using namespace std; extern "C" __declspec(dllimport) int Initialize(char* localPort, char* adminServerName, int rpcTimeout); int main() { int res = Initialize("7864", "6000@kabc", 10000); return 0; } I don't have the DLL's .lib file, so is th...
Hi! I'm writing a Browser Helper Object (BHO) for Internet Explorer in C#! I want to look for text nodes in the DOM, which requires me to traverse the whole DOM tree if I want to differentiate between text nodes and other types of nodes. This is supposedly time consuming in C#, but should be almost instantanious in C++ (?). Is there a...
