If you call LoadLibrary without a path (e.g., LoadLibrary("whatever.dll"), Windows will generally follow its standard search algorithm, the same one it uses to find EXEs. My question is this: suppose that an application manifest specifies specifies a particular version of a system DLL, say, comctl32.dll 6.0. In that case, will LoadLibra...
I have a .NET application and need to load a native library whose location is specified by the user. PInvoke looks like it'll only load from the global search paths (or a path specified at compile time?). Would the best method be to create a C++/CLI assembly which calls LoadLibrary at runtime? Would C++/CLI be simpler than C# PInvokin...
i'm usually using Win32 API in c#.NET. But not declare all in one application. Sometimes usually using user32, sometimes gdi32 ... I think when i declare all api function, those use lot of memory. What is the best way using API in .NET ? ...
Hi I'm getting really strange behavior in one of the DLLs of my C++ app. It works and loads fine until I include a single file using #include in the main file of the DLL. I then get this error message: Loading components from D:/Targets/bin/MatrixWorkset.dll Could not load "D:/Targets/bin/MatrixWorkset.dll": Cannot load library Matrix...
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!...
We would like to hook calls to LoadLibrary in order to download assemblies that are not found. We have a handler for ResolveAssembly that handles the managed assemblies, but we also need to handle unmanaged assemblies. We have attempted to hook LoadLibrary calls by re-writing the imports table via techniques specified in "Programming ...
I have a dll "mytest.dll" that when loaded via LoadLibrary(), returns NULL (and 127 as the GetLastError()). If I use DependencyWalker on "mytest.dll", it reports that it should load correctly and that all DLLs are found correctly. Running the profiler option of DependencyWalker on the host exe gives me this relevant section in the log:...
Threads in Perl by default take their own local storage for all variables, to minimise the impact of threads on existing non-thread-aware code. In Perl, a thread-shared variable can be created using an attribute: use threads; use threads::shared; my $localvar; my $sharedvar :shared; HP-UX runtime loader does not support dynamic load ...
I have a JD Edwards business function, which is written in Microsoft Visual C++ as a C module. I'm using LoadLibrary to access a third party DLL. In a standalone test program, the code runs just fine. When I run it from within JDE, LoadLibrary returns NULL and GetLastError returns 126, which means The specified module could not be found ...
I'm having trouble with LoadLibrary() and getting an error that doesn't make sense to me: ::SetLastError(0); m_hDll = ::LoadLibrary(szName); if (m_hDll == NULL) // Failure to load the DLL. { DWORD err = GetLastError(); } The error is 127 ("The specified procedure could not be found.") That doesn't make any sens...
Hello, Right after I moved from XP to Vista,I realized my C# programs don't work. This is the situation: I wrote a C++ dll that I use in my C# application.The DLL worked fine in XP,but when I moved to Vista it's not longer working in C#. I tested it in Delphi,works fine,but C# - no. I wrote additional code to make my check easier in ...
I'm working on a piece of C++ software which runs on all Windows versions between Windows XP and Windows Vista. In my code, I developed a DLL which links against a standard library (the Qt library). Once my software is deployed, it's not unusual that the user doesn't have the exact same Qt build on his system but a slightly different con...
Let's say that I have the following code that's run in one thread of a multi-threaded COM application: // Thread 1 struct foo { int (*DoSomething)(void ** parm); }; HMODULE fooHandle = LoadLibrary("pathToFoo"); typedef int (*loadUpFooFP)(foo ** fooPtrPtr); loadUpFooFP loadUpFoo; loadUpFoo = (loadUpFooFP)GetProcAddress(fooHandle, "f...
I am writing a JNI program and I want to unload the dll after i hava finished using it. What can I do for this purpose? I couldn't find a unloadLibrary() method in the Javadoc. ...
Basically I have a header file like this: #if WIN32 typedef DWORD (WSAAPI *SocketStartup) (WORD wVersionRequested, LPWSADATA lpWSAData); typedef SOCKET (WINAPI *MakeSocket)(IN int af, IN int type, IN int protocol, IN LPWSAPROTOCOL_INFOW lpProtocolInfo, IN GROUP g, IN DWORD dwFlags ); typedef DWORD (WINAPI *SocketSendFu...
My scenario is as follows: my application depends on a certain DLL (I use it's lib during linkage). However, when my application executes, I want to explicitly load that DLL using LoadLibrary. However, by default, when the code reaches a scope where that DLL is needed, the environment automatically look it up, and then loads it. I want t...
I have written some sample program and DLL to learn the concept of DLL injection. My injection code to inject the DLL to the sample program is as follows (error handling omitted): std::wstring dll(L"D:\\Path\\to\\my\\DLL.dll"); LPTHREAD_START_ROUTINE pLoadLibraryW = (LPTHREAD_START_ROUTINE)GetProcAddress(hKernel32, "LoadLibraryW")...
Hi..! I have a native C++ application (no fancy .Net stuff just C++). However it uses some optional .Net assemblies through mixed mode wrapper dll files. These dlls are loaded using delay load. Thing with mixed mode wrappers is they need to be fully trusted in order to load. So when the application try to use the dll if it is not there ...
Hi, I am unable to load my test.dll (in VC++ - MFC) using LoadLibrary() API. I get error code 126 (Module not found)using GetLastError(). By dependency walker I have come to know that my test.dll depends on "xerces-c_2_7.dll" and "Xalan-C_1_10.dll". These dlls were already present on the same path as the exe. Still I am getting the error...
Let me start off by saying I had one DLL loading in just fine. But when I go to load a second DLL it always errors out with a "Invalid Access Memory Location (998)" error. In my project the DLLs basically contain the code needed to run an AI. Another application I built allows you to write simple code and then behind the scenes it compi...
