Generally, You have some trouble with optimizations. You have to switch on the release version, and then to REBUILD ALL the code. During the compilation and/or linking process, You have to watch carefully at the bottom of the dev. studio, where the warnings/error messages will be shown. Try to make changes the compiler suggests. If the code doesn't work again, try to switch off as many optimizations as You can. After that, rebuild the code again. You can hope that the code will work OK without any optimization. If the problem disappears, You can try to switch on the optimizations one-by-one, and then rebuild the project any time, searching the bug this way. Anytime, watch on the warnings carefully. By the way, as I know, the stack under debug version has some predefined limit. Try to find the stack settings under the release version, and adjust the value - for example, 1MB or more.

Are you using MFC and custom message handling (ON_MESSAGE, ON_REGISTERED_MESSAGE) at all?
If so, check that your handler functions for those messages are declared
afx_msg LRESULT funcname(WPARAM,LPARAM)
and not anything else. This is a common cause of "works in debug, crashes in release".
Alternatively, modify your link properties to generate debugging information, and run the release version under the debugger. You can do this without turning off optimisations. This might help you find the area that's at fault.

this way
m_button.SetWindowPos(NULL,intWindowWidth - 147, 11, intWindowWidth - 179, intHeight - 59, SWP_NOZORDER);
or
m_button.MoveWindow( intWindowWidth - 147, 11, intWindowWidth - 179, intHeight - 59 )

You can use MoveWindow in wm_size

lvi.cchTextMax=512;
lvi.iSubItem=1;
lvi.pszText=_item;
// WriteProcessMemory(process, _lvi, &lvi, sizeof(LVITEM), NULL);
// ::SendMessage(myHwnd1, LVM_GETITEMTEXT, (WPARAM)0, (LPARAM)_lvi);
// ReadProcessMemory(process, _item, item, 512, NULL);
lvi.iItem = 1;
lvi.iSubItem = 0;
lvi.pszText=_item;

Hi All,
I created one MFC extension dll and loaded the exporated function in another sample
MFC SDI application on click of the toolbar events.This application is almost looks
simmilar to paintbrush where the exported functions are having the implementaion of
painting methods.The MFC sample EXE is just to call the extention DLL and call each
exported fucntion(in .DEF file of MFC Extension DLL) to test whether the actions are having or not but for one function i am getting runtime error while excuting the MFC
sample EXE i.e. "Debug Assertion Failed".
Program path of the sample MFC SDI exe......
File : wingdi.cpp
Line : 1054
I am giving following code snippets....
HDC hdc = NULL;
UINT uIntRect = 0;//RECTANGLE;
HWND hwnd = NULL;
BOOL uReturnVal= FALSE;
LPFNDLL_drawShape lpfndll_drawRectangle;
HMODULE hModule = LoadLibrary("D:\\FancyViewer\\Notebook_13July2006\\Notebook\\Debug\\Notebook.dll");
if(hModule)
{
lpfndll_drawRectangle = (LPFNDLL_drawShape)GetProcAddress(hModule,"drawShape");
if (!lpfndll_drawRectangle)
{
AfxMessageBox("GetProcAddress() method is failed");
FreeLibrary(hModule);
return;
}
else
{
CRect rect;
GetClientRect(rect);
CPaintDC dc1(this);
CDC dcMem;
dcMem.CreateCompatibleDC(&dc1);
hwnd = (HWND)dc1.GetWindow();
hdc = dc1.Detach();
uIntRect = RECTANGLE;
// call the function of drawShape method for rectangle of Notebook.dll
uReturnVal = lpfndll_drawRectangle(hdc,uIntRect,hwnd);
ASSERT(uReturnVal == TRUE);
char buffer[65];
MessageBox(_itoa(GetLastError(),buffer,10),NULL,MB_OK);
return;
}
}
else
{
AfxMessageBox("Load library failed");
return;
}
GetLastError();

Is it possible to use an inherited class (CIosDialog : CDialog) as the base class in ClassWizard (instead of seeing CDialog as the base class, CIosDialog as the base class)?
Thanks.

Add the class as a generic class and then type in the base class name in the New class dialog.

Hello,
I am curious to know if there exist a built-in Regular expressions algorhythm in C++ that can search patterns in a file and display them on the screen?
Thanks

Harold_Wishes wrote: display them on the screen?
I don't believe any Regular Expression Engine will know anything about displaying results on a screen.
Harold_Wishes wrote: can search patterns in a file
It is also unlikely that a Regular Expression Engine will know about searching files.
Harold_Wishes wrote: built-in Regular expressions algorhythm
Regular Expressions are not part of the ISO C++ standard... yet. There is a Regular Expression Library in Boost (boost.org)

I am trying to create a dynamic string array m_pSentences[iLineCount], where iLineCOunt is the number of lines in a text file.
What should the synthax be?
Error:
(35): error C2440: '=' : cannot convert from 'char (*)[1000]' to 'char *'
Code:
char strSentence [MAX_SENTENCES_PER_FILE + 1] [MAX_CHARS_PER_SENTENCE + 1] = {""};
char strFileToRead[MAX_FILEPATH_LENGTH + 1] = {"c:\\temp\\testfile.txt"};
int iLineCount = 0;
// read the file and update temporary array
fstream file_op(strFileToRead, ios::in);
while(!file_op.eof())
{
file_op.getline(strSentence[iLineCount], MAX_CHARS_PER_SENTENCE);
iLineCount++;
}
file_op.close();
// create an array of sentences
char *m_pSentences;
m_pSentences = new char[iLineCount + 1] [MAX_CHARS_PER_SENTENCE];
for (int iIndex = 0; iIndex <= iLineCount; iIndex++)
{
strcpy(strSentence[iIndex], m_pSentences);
//m_pSentences[iIndex] = *strSentence[iIndex];
}
for (int iIndex = 0; iIndex <= iLineCount; iIndex++)
{
cout << m_pSentences[iIndex] << endl;
}
delete [] m_pSentences;
}
