I debug a program with break points. I checked variable values all O.K.
Suddenly I got error message: Unhandled exception in Data.exe, OXC00000FD, Stack Overflow
WHat is the problem ? how to fix it?

Most likely you've got recursion that is too deep. i.e.
void Foo()
{
Foo();
}

 Thanks Steve. It looks like I solved the problem by reduce the size of arrays in the program.
However, now I got "unhandled exception, 0xC0000005 access violation"
Please help thanks

Can you show the code in question?

When I print (using the break points)the array value, e.g. data[1022] I got -1.#INDO and the error message says: Unhandled exception in Data_proc.exe:0xC0000005: Access violation
The function code where the message is generated:
void CBlast_vib_procDlg::complexFFT(float data[],unsigned int &nn,int &isign)
-> {
The data[1022] is within the range of the array defination.
Thanks

First, I create a bmp control on a Dialog, and set its ID to ID_MYBMP
second, I creat a member variable for the bmp control as m_mybmp;
third, I import a bmp file into the resource and name it IDB_MYBMP;
forth, I add following code to the funcion OnInitDialog()
BOOL CMyDlg::OnInitDialog()
{
CDialog::OnInitDialog();
CBitmap bmp;
bmp.LoadBitmap(IDB_MYBMP);
m_mybmp.SetBitmap((HBITMAP)bmp);
}
Thank you very much!!!

I'd check if bmp contains a bitmap, in the debugger. One way is just to call GetWidth and see what you get back. Then you can focus on the bitmap control as a possible source of the problem.

Try the following code as it works in my application for same
CBitmap bmp;
bmp.LoadBitmap(MAKEINTRESOURCE(IDB_SCHEDULE));
m_Schedule.SetBitmap(bmp);
bmp.Detach();
Hope it works for you

Hi ewighell
Do you set Bitmap(false) to true in property window from control?
|
|
|
|
|
The bitmap is destroyed when your CBitmap object goes out of scope. Make the CBitmap a member of your dialog class.
You may be right
I may be crazy

Hello,
I have a simple application where I try to display a dialog with a timer. It builds fine in the debug mode but not in the release mode. This is the error I get:
MainFrm.obj : error LNK2001: unresolved external symbol "protected: long __thiscall CMainFrame::OnNotifyPowerOnTime(unsigned int,long)" (?OnNotifyPowerOnTime@CMainFrame@@IAEJIJ@Z)
Release/NotifyTimer.exe : fatal error LNK1120: 1 unresolved externals
Relevant Code:
////////////////////////////////////////////////

#define WM_NOTIFY_POWER_ON_TIME (WM_USER + 1)

}
Any suggestions? Help??
Thankyou

Make sure that the OnNotifyPowerOnTime function implementation is not enclosed within a #ifdef DEBUG section (there is one around the Dump( ) and AssertValid( ) functions, it may have ended up inside that section).

Hi dabs,
You were right. The function was enclosed within a #ifdef _DEBUG section. I moved the function outside the #ifdef _DEBUG and recompiled and everything is fine. Thanks for your help.

LRESULT CMainFrame::OnNotifyPowerOnTime(WPARAM, LPARAM lParam)
{
...
...
return (LRESULT) 0;
}
where is the parameter of the wparam or is it ok...

Hi,
Do not need the actual parameter for WPARAM. As long as the defn. matches the decl. My code compiles fine in both the release (after the fix, thanks to dabs) and debug mode.

Does it make sense to use the .NET framework to develop a Win32 DLL that will reuse a lot of code from another project that uses MFC classes . I am going to stick to coding language as C++
If so what kind of solution ( project / language) is preferred ?

The answer is NO, it doesn't make any sense to me.

Sounds like you need to host an instance of the WebBrowser control. It's an ActiveX control so you'll to use MFC or ATL unless you want to implement the hosting code yourself (you almost certainly don't).

Thanks for the tip... I'd like to know if you think I should use (MFC or ATL) as I'm trying to read .html files on disk and display them within a screensaver. What is the easiest way of accomplishing this goal? I have to use the method declaration that follows, and all I have to use is a handle to the screensaver window (hWnd):
LRESULT WINAPI ScreenSaverProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)

I have to send some data as XML format to two different places right now I send all the data to one location through a socket and I need to create another socket to send some other data to second location as follow:
If (data1)
send to LOC1
else
send to LOC2
and this LOC1 connection should always be open
at this point I have the socket and connection to LOC2
Please help me to know how to make the second connection to LOC1 for the first connection to LOC2 the code uses CfgRemoteAddr=127.0.0.1 and some local port: local 1222 and remote 1223.
as follow:
if( hCfg->CfgApiSocket->CfgTCP )
.
.
..
if( !hSocket->sSend( hCfg->CfgApiSocket->CfgRemoteAddr, 0, ( LPSTR )XMLString, XMLSize ))
{
//Socket::sSend( LPSTR Address, INT PortId, LPSTR txBuff, INT txBuffSize )
tmpVar = 0;
memset( Buff, '\0', MAX_LOADSTRING );
tmpVar = hSocket->GetError(( LPSTR )Buff );
LogError( "WEAPIClass", "InSockProcess", "Error sSend Socket: %d, %s", tmpVar, Buff );
LinkStatus( IPC_LINK_DOWN, 0, NULL, 0 );
}
else
{
LogAppDiag( LOGGER_INBOUND_DIAG, XMLString, XMLSize, LOG_FORMAT_ASCII );
}
Thanks for any idea

for pointer variables defined globally say CmemObject *pMem = NULL
For a class CMyClass
CMyClass::Init()
{
pMem = new CMemObject();
}
CMyClass :: ~CMyClass()
{
if(pMem)
{
delete pMem;
pMem = NULL ;
}
}
Still shows a leak where the new operator is called .
Is it safe to ignore this error as I am finally de allocating it ?
|
|
|
|

Are you sure the destructor for CMyClass is getting called AND pMem is not set to NULL somewhere else?
Regards
Senthil

Also, in Init() you should not allocate if already done so or call delete pMem before calling new. You don't have to check for NULL since by definition, nothing will happen if it is NULL.
If the allocation should never be called twice, add: assert(pMem == NULL)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.
