I am in the midst of evaluating the benefits of changing our program from 30+ statically linked libraries to 30+ dynamically linked libraries. We hope by changing to DLL, it will reduce the link time. One immediate problem is the requirement to add __declspec in front of all the classes to create the lib file for other dlls to link. I...
When my program opens, before any of my code actually runs, it will automatically attempt to load various DLLs whose functions it imports. It looks in the folder that the app is in, and then in a few specific places like \Windows and \Windows\System32. If I want to use some custom DLLs, but I don't want to clutter up the app's folder w...
Hello, I'm converting a Delphi ISAPI dll to work better on IIS 7.0 and 7.5. The ISAPI used to read its configuration from the registry but I wanted to convert that to using the web.config file in the same folder. It worked fine with CGI but the ISAPI is another matter. I'm using GetModuleFileName to get the path of the module and, of c...
I know I can read the PE specification in order to write a code that does this. However, since I don't have a lot of time on my hands, I was hoping some of you might already have such a code sample ready to send. Important note: Is there any difference between 32bit and 64bit? Thank you for your time! ...
Hi guys! I have a new problem with my C++ DLL... I have tried exporting the entire class instead of only one method. But the program doesn't want to compile now because of that the global scope has no GetUrl Here is my "UrlConnector.h": #define ConnectMe __declspec( dllexport ) namespace ConnectHttps { class ConnectMe { void GetUr...
I am writing a project which makes use of the MS Chart for .net 3.5 utility. However, either all users will also need to install this, or I need to package the dll with the program. I can get Visual Studio to copy the dll to the folder with the program, but is it possible to make it embed the dll, so that there is only the one file? I...
I have a C# dll and want to use it in VB.NET. I'm using C# 2008 Express and VB 2008 Express. I have added a reference in a VB project to the C# dll. When I create an instane of a class in the C# dll, it gives the following error messsage: "Type 'RF.RabinFingerprint' has no constructors". How do I fix this? My C# dll code: using System;...
I am working on a plugin architecture and after some reading I have settled on one. The host class will be implemented in C# as well as some of the plugins for that host. The issue I am having is that some of my team uses VB.net. So the question, is it possible to implement a C# (plugin)interface in VB, such that when it is dynamically l...
hi all, I'm trying to use OpenCV in Visual C++ express edition 2008. I've installed OpenCV 2.1 and added necessary include and lib directories/files to my project dependencies. A system PATH is also present for "C:\OpenCV2.1\bin". When i compile and run the example program to open an image, I get a runtime error saying cxcore210d.dll i...
When Using DLLs or Code-injecting to be Specific this is an example class only intended for explaining class test { int newint1; char newchararray[512]; void (*newfunction1)( int newarg1 ); int newfunction2( bool newarg1, char newarg2 ) { return newint1; } } mynewclass1; that covers most common elemen...
I would like to prevent loading of malicious DLLs that may be possible through access of the current working directory as described in http://msdn.microsoft.com/en-us/library/ff919712(VS.85).aspx The solution implemented in our C++ apps was to make a WinAPI call to SetDllDirectory(""), which would effectively remove the current working ...
Hello everybody! After hours of penetrating Google I ended up here. I'll come straight to the point: I'm about to "refresh" my C/C++ skills and gain experience with the unmanaged world again. As a "basic" task I developed a little key logger (which are just a few lines with the Windows API) but now I want to extend it with a "stealth" f...
I see that ABE source given in this link http://acsc.cs.utexas.edu/cpabe/index.html is written in C for UNIX environment. I just have these libraries. Now, I need to use ABE in my C# project. How do I do that? how to migrate a project from unix environment to C# environment. How to compile the ABE project in windows environment using Mi...
Hi, We have an application that depends on a number of groups of third-party DLLs. Unfortunately, none of the writers of these third-party DLLs have named them very consistently so it is hard to see which DLL is part of what group. To try and manage this, we would like to put groups of third-party DLLs in a folder in our application fo...
I'm writing a python script in Linux, and need to call some Windows functions available in Wine. Specifically, AllocateAndInitializeSid and LookupAccountSidW, to determine who is logged in to a remote Windows computer. These functions are part of advapi32.dll in Wine (edit: using the answers, I was able to call the function, but Lookup...
Could anyone please give me a short working example of a C# class which can be compiled to a DLL, and an example of VB.NET-code creating an object based on this class and using its members (methods). The C# class has to have a namespace, at least one class definition (obviously) and some methods or whatever they ought to be called. I hav...
There is this great open-source OCR component that Google has been developing: http://code.google.com/p/tesseract-ocr/ They have a new version out (version 3) at the beginning of October 2010. But this new version no longer has a working C wrapper, and it's up to somebody in the Delphi community to get it to work from inside Delphi -- ...
Hi, My program tries to load some dlls. The problem doesn't come during the first load. But it comes every 7th time. I guess there is memory corruption. Is there a tool or something to debug the memory corruption for visual c++. I tried some memory leak tools but there is no memory leaks. please help!!! regards, Suresh ...
I need to forward a set of symbols from one DLL to another (to support some versioning scheme, PEP 384 if you wonder). It works fine for functions; I write a module definition file, saying LIBRARY "python3" EXPORTS PyArg_Parse=python32.PyArg_Parse PyArg_ParseTuple=python32.PyArg_ParseTuple PyArg_ParseTupleAndKeywords=python32.PyAr...
