I want to load a different version of a DLL than is present in the working directory of the application. For this I need to hook the LoadLibrary call so that when the application makes a call to load the DLL I can substitute it with the newer version of that DLL transparently. I tried using NCodeHook and have the following code in my DLL...
Hi, I need to open a html help file from within a legacy windows application written in old version of C++ Builder. HtmlHelp is loaded via HtmlHelp.ocx, which I am loading via LoadLibrary. This has worked fine for years, but it does not work anymore in Windows 7 x64. It might also fail under Windows7 x86, but I don't have any computer...
Say I have a DLL that has the following static/global: ClassA Object; Along with the implementation of ClassA, it also contains a 'regular' ClassB, which will not work properly if ClassA has not been constructed yet (which is why I've made ClassA is a static/global). In Windows, I believe that the DLL loader will load this DLL on the...
Right now I do something like this and it seems messy if I end having a lot of functions I want to reference in my DLL. Is there a better and cleaner way of accessing the functions without having to create a typedef for each function definition so that it will compile and load the function properly. I mean the function definitions are al...
I have the following items in a structure - Dll name (absolute/relative path) - Function name in the dll - number of parameters - Array of parameter types and values With these information, I need to load the dll and call the function. To load the dll - I would use loadlibrary To get the address of the function - I would use GetProcAdd...
I am trying to call LoadLibrary and load Delphi dll in ASP.NET application. On my production machine everything works fine (using VS integrated server), but when I place it on destination server, LoadLibrary returns IntPtr.Zero. File.Exists(libraryName) returns true. What can be the problem? ...
First, COM is like black magic for me. But I need to use COM dll in one project I'm working on. So, I have a DLL I am developing and I need some functionalities that are available in a separate COM DLL. When I look to the COM DLL with Depends.exe I see methods like DllGetClassObject() and other functions but none of the functions I'm i...
I am writing a DLL to plug into another (3rd party) application. The DLL will need to depend on another set of DLLs (for license reasons I cannot link statically). I would like my DLL to be "xcopy-deployable" to any directory. I would also like not to require adding this directory to the path. If I just build the DLL the usual way, Win...
Is there a way to load a 32bit DLL library (something with the same usage as LoadLibrary) I would like to use that function along with GetProcAddress. I looked at WOW, but it does not seem to offer the functionality. The functionality should exist, since tools like DependencyWalker are able to read the symbols of a 32bit dll even though...
I'm making a programming learning game for my senior project and I'm looking for a compiler that can compile a DLL that can then be dynamically loaded into a Visual Studio 2008 C++ application. The important idea here is that the compiler is redistributable. If VS was redistributable I'd be using that. So far I'm had some success using...
Hi all, Technical summary: I'm developing a Java web service deployed on GlassFish v3, running on CentOS 5. My web service uses functionality provided by a native library (.so) . The native library works fine, however I am not having much luck in configuring the environment correctly to load the native library yet not be affected by we...
I am working on a Windows application (EXE) that uses multiple DLLs. Development is in VCExpress 2005 (VC 8.0), using C only. Some of these DLLs are plug-ins/add-ons/extensions that are dynamically loaded using [LoadLibrary](http://msdn.microsoft.com/en-us/library/ms684175(VS.85).aspx) according to a configuration file read by the EXE....
I came across the following weird chunk of code.Imagine you have the following typedef: typedef int (*MyFunctionPointer)(int param_1, int param_2); And then , in a function , we are trying to run a function from a DLL in the following way: LPCWSTR DllFileName; //Path to the dll stored here LPCSTR _FunctionName; // (mangled) name...
Hi, While loading a dll file, I am getting the following exception: Exception in thread "main" java.lang.UnsatisfiedLinkError: D:\Transliteration\rlpnc-3.1.0-sdk-ia32-w32-msvc80\rlp\bin\ia32-w32-msvc80\btrntjni.dll: The system cannot find message text for message number 0x%1 in the message file for %2 at java.lang.ClassLoader$Na...
I have a 32-bit exe that needs to dynamically load a 64-bit dll when it detects that the operating system is 64-bit. Is this possible through LoadLibrary? If not, is there another way to accomplish the same goal? ...
I'm writing a wrapper program that loads Winamp input plugins. I've got it working well so far with quite a few plugins, but for some others, I get an error message at runtime when I attempt to call LoadLibrary on the plugin's DLL. (It seems to happen mostly with plugins that were included with Winamp.) A dialog appears and gives me t...
Two Delphi programs need to load foo.dll, which contains some code that injects a client-auth certificate into a SOAP request. foo.dll resides in c:\fooapp\foo.dll and is normally loaded by c:\fooapp\foo.exe. That works fine. The other program needs the same functionality, but it resides in c:\program files\unwantedstepchild\sadapp.ex...
What's the best way for loading a dll from a dll ? My problem is I can't load a dll on process_attach, and I cannot load the dll from the main program, because I don't control the main program source. And therefore I cannot call a non-dllmain function, too. ...
Here's my problem: I would like to create two separate instances of the same DLL. The following doesn't work because Handle1 and Handle2 will get the same address Handle1 := LoadLibrary('mydll.dll'); Handle2 := LoadLibrary('mydll.dll'); The following works, but I have to make a copy of the DLL and rename it to something else (wh...
We've been plagued for several years by occasional reports from customers about a non-descript error message "Cannot set allocations" that appears on startup of our app. We have never been able to reproduce the problem in our own test environments so far. I have now run out of ideas for attempting to track this down. Here's a collection ...
