  I need to write a Simple Loader which can run simple EXE(PE Format) file. My loader can parse PE header: IMPORT,EXPORT,RELOC...... I bulit AP.exe with VS2005, and AP.exe imported msvcr80d.dll.

• lou_1 DLL questions with Visual Studio using C++

  I'm new to Visual Studio (I have VS 2005 Standard Edition) and I'm trying to learn how to code a DLL with some standard functions I use instead of including a cpp file into every project that needs it. Using the help I got a DLL to work with a Win32 project using __declspec ( dllexport ) and __declspec ( dllimport ). When I try a Windows Form Application I get lots of errors with the linker because of the CLR from what I can tell. I tried various things I read and could never get it to work. I decided to try my hand at a .def file and after reading up on how you write it up I have some questions. Can you export overloaded functions using a .def file From what I read I have to include extern "C" to keep C++ name mangling from ...Show All

• A.Kahn Why does compiling with Unicode cause buttons to look different than with Multibyte or none??

  I want my application that was build with Visual Studio 6.0 to look the way it does when I compile with the Unicode Project Property option using Visual Studio .net 2005. But, if I compile with the Unicode option, I have to change the way I use strings throughout my application. Is there some way to get the newer visual effect (ie. buttons with rounded corners, radio buttons change with mouse-over) without having to make extensive code changes MFC application built by VS 2005 Application Wizard, has the following code in stdafx.h: #ifdef _UNICODE #if defined _M_IX86 #pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='659 ...Show All

• thomas woelfer Program runs slower when compiled with Visual Studio 2005 (in Release with optimization)

  Hey, I have a performance problem with the new Visual Studio 2005. My code (which is a genetic algorithm) is 3 times slower when compiled under Visual Studio 2005 compared to when I was compiling it under Visual Studio 2003. With Visual Studio 2003, it used to run in 3.0639 seconds, and now it runs in 9.0031 seconds. I run both code in Release. I tried every optimization option, and adding the /D_SECURE_SCL=0 compiler command to the project options with only minor differences. Is there any other way to get back to the speed Visual Studio 2003 It is a bit absurd to upgrade to a new compiler and get lesser performances. Thanks a lot!!!

• Vivek S BuildAction Property in C++?

  I can not find the Build Action Property seen in C# on an XML file, in my C++/CLI project. I am converting a large C# control to C++/CLI. The author of the control seems to have embedded an xml file into the assembly. I need help in figuring out how to do this in C++/CLI. The property list of the file under C# is considerably different than the propery list uder C++. Among the missing is: "Build Action: Embedded Resource". Please refer me to documentation where I can learn how to embed an xml file as a C++ project resource. I'm guessing a bit because I haven't tried it but it looks like the Assembly Linker can embed a arbitrary file into an assembly.

• mhodder Visual Studio 2005 can't find the standard include directories for C++ project

  I have just installed Visual Studio 2005 Team Edition for Software Developers and imported a project that was created in Visual C++ 6. Building the project gave hundreds of errors (C2039 'name' is not in std namespace). After a lot of hair tearing (which I just can't afford being a bit thin on top) I found that VS 2005 couldn't find the standard include files. After I added C:\Program Files\Microsoft Visual Studio 8\VC\include and C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\Include in the VC++ Directories under options it built correctly. So why can't VS 2005 resolve the directories $(VCInstallDir)include etc. I still have VC++6 installed as well as Visual C# 2005 Express Edition. My Windows version is Microsoft ...Show All

• rohit_c4u About CRuntimeClass::m_lpszClassName

  Just wondering why this member is only "A null-terminated string containing the ASCII class name." The problem I am having is when I am using CMapStringToPtr::LookUp(). Parameter 1 expects LPCTSTR. When _MBCS is defined and I pass in m_lpszClassName (which is LPCSTR) it works just fine because the 1st parameter for lookup is type TCHAR which in this build will just be CHAR. However I now want to do the same thing but with UNICODE defined. Now I get the "error cannot convert LPCSTR to LPCTSTR". I know I can use MultiByteToWideChar() to convert the CHAR to WCHAR but is it really necessary for me to do this Is there some compiler setting that I am missing that will handle this Also what if I wanted to build in either ...Show All
