    - MFC Compilation Problems in Visual Studio 2005 Using Visual Studio 2005, I am currently trying to learn MFC. I would consider myself relatively competent in C++, however, when trying to build a project created by using the MFC application wizard with default settings, before even modifying the project, I recieve 103 errors and 25 warnings in debug configuration, and 163 errors and 20 warnings in release configuration. Does anybody know what I have done wrong If you would like a list of the errors or a sample of the code or screenshots or anything of that nature, please send me an email at: rob@slifkin.net , and I'll be happy to send them.

    - File streaming in a function Hey, I'm having trouble with file streaming. I just need my program to write all of its data to a file instead of a command prompt. However most of my outputs are with in functions. Here is an example (please ignore improper coding ect on everything except file streaming. #include <fstream> int main () { int this = 0; int that = 1; fstream record; record.open ("data", iostrunc); traverse (this, that); record.close(); } void traverse (int this, int that) { record << this << that << endl; } Do I need to pass "record" in as a parameter If so, how Thanks in advance for the help!

    - exactly same code, warning C4311: 'type cast' in a MFC dialog, no warning in console application i have a window console application used to generate signal ouput from a board. When i try to write this into a MFC dialog, using the same code(i mean a specific part), a warning occurs. The signal generator board comes with its own .h file and library that includes driver functions. in one .h file, following types are defined: # define int16 short int # define int32 long int # define ptr8 char* in the library, following driver function prototype is defined; HEAD SpcSetParam (int16 nNr, int32 lReg, int32 lValue); in my header file; i declared 2 char pointers: ptr8 pbyData[2]; in my cpp, i allocated 2 char array; for (i=0; i<2; i++) pbyData = (ptr8) GlobalAlloc (GMEM_FIXED,1024); then i write data to the array,and need to pass the address of this two array to the driver function. Using the function provided: for (i=0; i<2; i++){ nErr = SpcSetParam (hDrv, SPC_FIFO_BUFADR0+i, (int32) pbyData ); <---------warning occurs here ignore the nErr and hDrv, SPC_FIFO_BUFADR0+i is the value for specific register, and (int32) pbyData i think is the address of the the array the code works fine in console application, no warnings, however, using the same code in a MFC dialog, following error generated: warning C4311: 'type cast' : pointer truncation from 'char *' to 'long' could anybody tell me whats going on and how to fix it Tag: Visual C++ General My Program Takes a lot of Memory Visual C++

I knew that I think IImnAccountManager could do this,but this interface has been deprecated now for vista and also login of creating account been changed in vista. Vista is creating one .oeaccount file for each account into "%UserProfile%\Local Settings\Application Data\Microsoft\Windows Mail". folder. but here I am facing issue of setting binary password and setting as a default account. Please help me if anybody knows anything about this,that would be great for me to know something more about windows mail. Thanks, Prakash.

    - Bizarre bug using std::ofstream and TRACEFILE This is a bizarre bug in that the code to reproduce it is so normal. Yet I get the same error using both VC 2005 and VC 6 using two entirely separate systems. The VC 2005 system I access using Terminal Services and is totally separate from the system I have with me physically that has VC installed; it has never had VC 2005 installed. To reproduce, the following four files must be used as shown. If I try to combine files or anything, the problem goes away (or at least the symptom). If I move the ~classLoggerThread body into the class definition, the symptom is gone. If I remove the TRACEFILE symbol there is then no error. If however I use this exact code then both VC 2005 and VC 6 get an access violation in ~basic_ofstream(). The exact error is: Unhandled exception at 0x104d234c (msvcp80d.dll) in BugSample.exe: 0xC0000005: Access violation reading location 0xccccccd0. stdafx.h Code Snippet #pragma once #include #include #include TestLogger.cpp Code Snippet #include "stdafx.h" #include "LoggerThread.h" int main(int argc, char* argv[]) { classLoggerThread LoggerThread; return 0; } LoggerThread.h Code Snippet class classLoggerThread { #if defined(TRACEFILE) std::ofstream TraceFile; #endif public: virtual ~classLoggerThread(); }; LoggerThread.cpp Code Snippet #include "stdafx.h" #define TRACEFILE #include "LoggerThread.h" classLoggerThread::~classLoggerThread() {} I hope someone can confirm that I am reasonably sane about this; that there really is something strange happening. Assuming this is a bug, then I will report it. Note this code is the result of reducing a larger peice of code to a bare minimum necessary to reproduce a problem. If I knew for sure what to do to avoid the problem, I would work around the problem. I have wasted so much time that I want to report the problem; I assume everyone agrees that a bug such as this is unacceptable. I realize that perhaps the most we can get from Microsoft is a workaround, but it will certainly help to know what to avoid doing. I put the code above into a new (empty) console application project and I changed nothing in the properties/settings; I even did not change the precompiled headers option.

    - filling and writing multidimensional vectors Hello, I have 3d image data ("pixelData") that I read into a dynamic array (size "countPix"). This data is then loaded into a 3d vector so that I can easily rotate the data. I have included the code below which does seem to do the job. However, it is really long winded with loads of loops. Could someone tell me how to make this code work faster Thanks in advance. //images upside down so sort em ... Uint16 *pixelsort; pixelsort = new Uint16 [countPix]; //multi dims dinnae work so use vectors to reverse vector< vector< vector<Uint16> > > my3Ddata; //generate a 3d space of the correct size my3Ddata.resize(irows); for(int i=0;i<irows;i++){ my3Ddata .resize(icolumns); } for(int i=0;i<irows;i++){ for(int j=0;j<icolumns;j++){ my3Ddata [j].resize(iframes); } } //load the space up for(int i=0;i<irows;i++){ for(int j=0;j<icolumns;j++){ for(int l=0;l<iframes;l++){ my3Ddata [j][l]=pixelData[ i + (j*icolumns) + (l*irows*icolumns) ]; } } } //flip top to bottom for(int i=0;i<irows;i++){ std::reverse(my3Ddata .begin(),my3Ddata .end()); } //make standard array for output -- really ugly for(int i=0;i<irows;i++){ for(int j=0;j<icolumns;j++){ for(int l=0;l<iframes;l++){ pixelsort[i + (j*icolumns) + (l*irows*icolumns)]=my3Ddata [j][l]; } } } //write out image ofstream myBinFile("C:\\***\\test.img", ios::out | ios::binary); if (! myBinFile){ cout << "Error opening output file" << endl; return -1; } myBinFile.write( (char *)pixelsort, countPix*2 ); myBinFile.close(); delete [] pixelsort; Tag: Visual C++ General My Program Takes a lot of Memory Visual C++

    - convert VS6 -> VS 2005 and ON_EVENT_ doesn't work I've just converted a VS 6 project to VS 2005. I converted by opening the VS 6 project in VS 2005 and accepting the conversion option. Two errors occur (1) during a build I get a 'hcw' file not found, and during execution my ON_EVENT_s aren't honored. Help says that 'hcw' is a tool. I suppose I'd like to remove it but I don't know how. Redoing the ON_EVENT_s would be a real chore, is there anything I can do to recover the old events after conversion - they are all still in the Dialog subclass header and in the BEGIN_MESSAGE_MAP section of the .cpp file.

    - passing control handle to unmanaged directx dlls to paint - result is flickering! Hi, I have a third party unmanaged DLLs which requries a window handle to do some painting on. My attempts have been to pass the control::handle property to this DLLs. The DLLs declaration expects a void* hWnd. Below is the declaration. CyResult CyDisplayEx:: Open ( void * aWindow , unsigned short aColumns = 1 , unsigned short aRows = 1 , bool aFullScreen = false ) [virtual] What I did was is follows. Panel* test = new Panel(); System:: Intptr handle = test->Handle; void __pin* hwnd = (void*)handle; CyDisplayEx:: Open(hwnd, 1,1, false); The result & problem The unmanaged DLL starts painting in the window area. It continues to update with significant flickering. At this point, I have not managed any of the paint event to that window. Additional information about the 3rd party DLL. I know that the DLL uses directdraw to paint in the window. It also has the following notes: Note: On Windows, the aWindow parameter must be a valid HWND (WIN32 SDK). It is important that the user��s window handling call the following functions on specific Windows events: WM_MOVE ==> OnMove( unsigned int aPosX, unsigned int aPosY ) ; WM_SIZE ==> OnSize( unsigned int aSizeX, unsigned int aSizeY ) ; WM_PAINT ==> OnPaint() ; I have been strugling with this for almost a week If anyone has any insight, PLEASE don't hesitate to help.

    - CryptUI.dll I recently created an application that is using a function in CryptUI.dll. I developed this application on a Vista machine, and then tested it on an XP machine. Everything works great. However, I moved the program to a Windows 2003 system and the program fails. I get an error message that says Windows can't find the entry point for my function (CryptUIDlgSelectCertificateFromStore) in CryptUI.dll. I tried copying the dll over from my XP machine to my Windows 2003 machine, but that didn't work either. Does anyone have any ideas how I can solve this problem Thanks in advance.

    - "Unresolved external symbol" after upgrading to VS05 Hi All, I have a project that build and worked fine all the way through Visual Studio 2003. After upgrading to VS2005 and rebuilding the two dependent libraries I am receiving a linker error on the parent DLL stating: Error 1 error LNK2001: unresolved external symbol _hInstDLL stdafx.obj Error 2 error LNK2001: unresolved external symbol _hInstGenDLL stdafx.obj There is a common header included in one of the libraries and the parent DLL. All files are C++. I can't get rid of the "extern "C"" section because of legacy stuff elsewhere. That header file contains amongst others the following code: #ifdef __cplusplus extern "C" { #endif extern HINSTANCE hInstDLL; extern HINSTANCE hInstGenDLL; One of the source files in the library contains the following code fragment: extern "C" { HINSTANCE hInstDLL1Way; HINSTANCE hInstGenDLL; } As you can see ( and not for the lack of a blinking cursor in this window on my FireFox browser ), I am defining the two variables. The library builds cleaning with no errors or warnings. The main DLL builds cleanly to, but now throws a the two linker errors, which is really one linker error. The old version of VS (2003) correctly located the two symbols in the library. What do I need to do now Thanks in advance, Marci Weinberger Tag: Visual C++ General My Program Takes a lot of Memory Visual C++

Bruno van Dooren

Yeah but what does your program do

If my program does char* mem = new char[300000000];

It will also use 300 MB of memory.

Try to find out what is in that 300MB, and who allocates it.

I traced my program and I could find where is the problem:
ResxResourceReader ^ resx = gcnew ResxResourceReader("Buckets.resx");
IDictionaryEnumerator^ id = resx->GetEnumerator();

The line in red, where ever in my code i've used this line it's added MBs to the memory used by my program.
