copied!<p>In C++/CLI you can use P/Invoke as in C#.</p> <p>If you don't want to use P/Invoke, the other way is to load the DLL with <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms684175%28v=vs.85%29.aspx" rel="nofollow">LoadLibrary</a> and get pointers to the functions with <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms683212%28v=vs.85%29.aspx" rel="nofollow">GetProcAddress</a>.</p> <hr> <p>Here's the equivalent of the C# code in C++/CLI:</p> <pre><code>using namespace System; using namespace System::Runtime::InteropServices; private ref class NativeMethods abstract sealed { internal: [DllImport("MimeTex.dll")] static int CreateGifFromEq(String^ expr, String^ fileName); [DllImport("kernel32.dll")] static IntPtr GetModuleHandle(String^ lpModuleName); [DllImport("kernel32.dll")] [returnvalue: MarshalAs(UnmanagedType::Bool)] static bool FreeLibrary(IntPtr hLibModule); }; </code></pre> <p>As you can see it's almost identical to the C# code except for some minor syntax changes.</p> <p>Here's how you would use LoadLibrary and GetProcAddress (which has the advantage of not requiring marshaling, which is unnecessary in C++ anyway):</p> <pre><code>HMODULE hModule = LoadLibrary(L"MimeTex.dll"); int (*fpCreateGifFromEq)(WCHAR*, WCHAR*) = GetProcAddress(hModule, "CreateGifFromEq"); (*fpCreateGifFromEq)(L"expression", L"filename"); </code></pre> <p>You don't need to do that for GetModuleHandle and FreeLibrary, because they're from kernel32.dll so you can just include Windows.h and call them normally.</p>
