Is it practically possible for a malicious developer exploit your application by swapping a genuine .dll file for a modified one. If so are there steps that can be taken to protect an app. Are there some types of functionality that should not be placed in .dlls for example? ...
Hello everybody... I need to return objects from a DLL made in Delphi, to an app made in Delphi, too. The objective is to do a subsystem that can be modify in the future without to modify the main app. So, I imagine developing the subsystem in a DLL is a (good??) idea... i am programming in Windows XP, Delphi 7. I did read DLLs only ret...
Ok everyone, Got a wierd one here. I've written approx 4 projects that utilize a central DLL for database access. The DLL was written in VB.NET using the .NET 3.1 framework. All the code works great. Recently, I went through all the code and updated the connection strings to use a new username and password since they were using the S...

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...
EDIT: I can run the same program twice, simultaneously without any problem - how can I duplicate this with OpenMP or with some other method? This is the basic framework of the problem. //Defined elsewhere class SomeClass { public: void Function() { // Allocate some memory float *Data; Data = new float[1024]; // Dec...
I have a mex module called p.mexw64 which uses another dll called p.dll The mex module loads p.dll when it is loaded since it is linking to it's lib file. Normally, when I want to recompile p.dll I do clear p;. This unloads p.mexw64 and then in turn also unloads p.dll. Except when it doesn't. In some scenario which I can't really quan...
I have a callback inside a C DLL (static void __stdcall) . I want another program to register it as such (by passing it the func ptr) and then call the calback inside the DLL. I have had no luck so far. However, the same callback works if its inside a regular C++ program. I am now wondering if having callbacks in a DLL is even possible. ...

It seems that when a thread is created from within DllMain upon DLL_PROCESS_ATTACH it won't begin until all dll's have been loaded. Since I need to make sure the thread runs before I continue, I get a deadlock. Is there any way to force the thread to start? ...
Hi I am developing a Qt application that uses a plugin (dynamic library) and I was wondering if there was a way I could build the application and library in one file (maybe using the QResource feature?) ...
I love that Qt is cross-platform but I want to make an application that will call into some Windows specific .dll's. Kinda like Google Chrome does with the glass on Windows Vista/7 (I know Chrome isn't written using the Qt framework just thought it was a good example). How can I do this in Qt? Is it feasible? ...

Hi, I believe the conventional way to deploy Crystal Report with a .NET program is to set it as a prerequisite in the publish settings and then a .msi will be packaged with the ClickOnce files on the web/network/CD/wtv. When the user runs setup.exe, it will check whether Crystal Report is on the client computer. If not, it runs the Cry...
With Delphi I wrote a DLL which can be called from Java via JNA (Java Native Access). Methods in this DLL are just simple operations, but for future use and more complex invocations I would like to know how I can use the Delphi debugger, if the DLL is called from Java directly (or from the Java IDE). ...

I have a class in a unit. Usually, when I changed the algorithm of its methods, I have to recompile it and deliver the patch as a whole. I think to create the instance of the class using DLL. After searching in delphi.about.com, I found that instead of using DLL, I can use BPL. It is a DLL for Delphi. The problem is almost all examples I...
