Splitting up a utility DLL into smaller components in C++
We have a core library in the form of a DLL that is used by more than one client application. It has gotten somewhat bloated and some applications need only a tiny fraction of the functionality that this DLL provides. So now we're looking at dividing this behemoth into smaller components. My question is this: Can anyone recommend a ...
Including dll's in the exe?
I have a project that relies on several dlls and once I compile it, it requires that I run the .exe in the same folder with the dlls. Can I package them together so I don't have to do that? For reference, I'm using C# ...
Loading Managed C++ DLL from plain C++ Program via LoadLibrary
Hi, I'm trying to get a simple mixture between Managed C++ and plain C++ working. I'm using Visual Studio 2005 but keep hitting a problem. Here's my setup. First, I have a simple DLL built from the code #using "mscorlib.dll" #include "windows.h" __declspec(dllexport) void sayHello() { OutputDebugStringA( "Hello from managed code!...
understanding WinDbg output

Sometimes when running the application i get the following exception: System.AccessViolationException: Attempted to read or write protected memory.

Rebasing - can't get odbcint.dll to load at its preferred base
The default base address for an .exe built in Visual Studio is 0x00400000. The default base address for d3dx9_30.dll and odbcint.dll (which both live in %windir%\system32) is also 0x00400000. So by default, exes that link to either of these dlls will have a runtime address collision. The OS automatically relocates the dll to a differe...
Code Randomization
I am trying to build a ReTrust system which requires that DLL files be transferred from one system to another. Thus to just add a bit of complexity, I would like to Randomize the code - i.e change the code in a way that every time I have to send a DLL, it will be different then the one sent previously. Please suggest some measures. (Note...
Track DLL dependencies for wrapping a native C++ DLL to .NET
I have a C++ DLL (no code) that I want to expose to .NET applications. After pondering all the options I have/know of/could find (COM, P/Invoke, SWIG, etc.), I'm writing a .NET Class Library (in C++/CLI). Now the resulting DLL (class library) requires the original DLL and its dependencies, too. My problem lies in automagically keeping t...
Exporting classes containing std:: objects (vector, map, etc) from a dll
I'm trying to export classes from a DLL that contain objects such as std::vectors and std::stings - the whole class is declared as dll export through: class DLL_EXPORT FontManager { The problem is that for members of the complex types I get this warning: warning C4251: 'FontManager::m__fonts' : class 'std::map<_Kty,_Ty>' needs...
non-unicode WM_CHAR in unicode windows
I have written a DLL which exports a function that creates a window using RegisterClassExW and CreateWindowExW. Every message is retrieved via GetMessageW(&msg, wnd_handle, 0, 0); TranslateMessage(&msg); DispatchMessageW(&msg); Also there is a program which loads the DLL and calls the function. Despite the Unicode window creation m...

Visual C++ - Linking plugin DLL against EXE?
I'm in the process of porting a large C++ application from Linux (gcc) to Windows (Visual C++ 2008) and am having linker issues with plugins. On Linux this wasn't an issue, as .so supports runtime symbol lookup, but dll does not seem to support this. Some background information: The application (the host), which hosts a scripting enviro...
dll release debug
Is it possible to have a project reference one DLL when compiling in DEBUG mode, and another DLL when compiling in RELEASE mode? See, we've got a number of legacy projects we want to go ahead and remove from the solution, and just keep the DLLs around as references until we can eliminate all of the references altogether. ...
Assembly DLL management in .Net
What is the safest way to make sure IIS picks up changes to a recompiled DLL? 1. Just copy the DLL in the /bin folder? 2. Clear the application cache? 3. Restart IIS? 4. Reboot the server? Note: I'm pretty sure options 3 & 4 would work, but they might be a tad drastic in a production environment ;-) ...
JclDotNet, and some odd calling patterns using assembler
We have our own glue-layer-code-thingamajig that allows us to host the .NET runtime in our Win32 Delphi program. This has allowed us to do a gradual transition to .NET over time. But, we have some problems with it from time to time, and yesterday I saw an answer here on SO that referred to Jcl's .NET host implementation, so I thought I'...
How do I silently register a COM assembly on a WinXP computer
I have a C++ console application to which I want to a Windows Form. I don’t want to use MFC because I don’t know how. Instead, I am using a C# to create the COM dll (Class Library). When I distribute the application and the dll to the target computer, I need to register the dll such that the application can see the COM interface and use ...

Problems using dynamic linked libraries (wxWidgets) from a DLL
We created a plugin; it is a DLL (Run-Time Dynamic Linking) which uses a 3rd party library (wxWidgets) and also links dynamically to that. The host software seems to scan our plugin, but exported functions are not called. We checked all dependencies with DependencyWalker. We see in the debugger that the plugin is loaded, but the DllMain...
