Actually no. Visual C++ .NET and Visual Studio .NET do NOT ship with a profiler. However, there is a coupon in the box that enables you to download a trial version of a Compuware profiler.
We're trying to figure out how to get a decent profiler back in the box -- I'm certainly aware that profilers are a core tool for C++ devs. But the one that used to ship with Visual C++ was deemed insufficient to work with Visual C++ .NET and we decided to abandon it.
Sorry - I know this isn't the ideal situation for you.

Thanks Nick for the quick response!
It's nice to see some MSFT people looking at forums.
I am also sad to find out about the missing profiler. Despite the fact that the Visual C++6 profiler was not too great, it was nevertheless usefull to quickly find out bottlenecks. I have uploaded the Compuware profiler community edition. I hope this will do the trick.
Note that I am working on my own tool to post-process computational fluid dynamics results (10+ millions triangles on cut surface displayed with OpenGL). Optimizing is therefore very important.
I sincerely hope that some kind of profiler will be added later on to the studio tools.
I would also add to the list of features: openMP for C++ ... which is much easier to use for parallel processing than the threads.
I know that Intel C++ has it. Is this compiler compatible with the MFC libraries and visual .net environment?
Thanks
Eric

I get linker errors when I try to do this, do I have to use a #pragma or something?
#include <iostream.h>
#include <afx.h>
int main()
{
CString c;
return 0;
}
Error:
--------------------Configuration: test - Win32 Debug--------------------
Linking...
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex

If you are using MS Visual Studio, go change your project setting to "Use MFC in a Shared DLL."

Ah, that works fine, but is there a way to do this directly in code alone so the setting is still listed as "Not Using MFC"? Thanks for the response by the way.

I am not sure about that. CString is a MFC class. That's the reason I ask you to change the project setting. Your other option is to use char type.
Maybe someone else can help you.

I know I can use other data types to do this, however I wanted to do this specifically with a CString. Thanks for the input.

If you want to use CString but not MFC, I use the excellent CStdString[^] class which is an exact clone of CString but using stl.
Cheers

I want to check for a certain condition when a user selects to drop down a box. If that condition is not met I want to display an error message and then NOT display the drop down.
Does anybody have any ideas on how to do this? I have tried everything I can think of. I have the error message and all of that but after the user selects ok on the message the box drops down with nothing in it.
Anybody?

I've added the CBN_DROPDOWN, but I don't know how to say "quit".

I'm not certain without trying, but I would think it would work something like this...
case CBN_DROPDOWN:
if(!ShowTheDropList) return;

hello,
does the possibility exist to convert hexadecimal in integer?
thanks,
mfc
|
|

|

Yes. In what context ? You can do this:
int n = 0x0BADF00D;
you can also use iostreams to display a number of any format as any other, my ostringstream article shows how.

sscanf[^] appears to be what you're looking for.

Discription: MFC application using Foward Declare.
What the program is Suppose to do:
Pressing the left mouse button calls m_CGoHereFirst.Funct1();
located in the class CGoHereFirst().
It Prints: "1st: Var = 5", which works fine.
It then calls m_CGoHereSecond->Funct2(); located in CGoHereSecond().
It is suppose to print "2nd: Var = 5", however I get the Error message;
"This program has performed an illegal operation and will be shut down"
Why is the second print message causing an Error?
How do I fix the problem?
Important header and cpp functions listed below:
HEADER FILE INFO:
CGoHereFirst.h:
class CGoHereSecond; // Part of 2nd Foward Declare
class CGoHereFirst : public CWnd
{
// Implementation
public:
CGoHereSecond *m_CGoHereSecond; // Part of 2nd Foward Declare
int Var;
void Funct1();
virtual ~CGoHereFirst();
};
CGoHereSecond.h: Forward Declare
class CGoHereFirst; // Part of 1st Foward Declare
class CGoHereSecond : public CWnd
{
// Implementation
public:
CGoHereFirst *m_CGoHereFirst; // Part of 1st Foward Declare
void Funct2();
virtual ~CGoHereFirst();
};
Foward_Declare.h:
// Implementation
public:
CGoHereFirst m_CGoHereFirst;
MEMBER FUNCTIONS:
void CForward_DeclareView::OnLButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
m_CGoHereFirst.Funct1();
CView::OnLButtonDown(nFlags, point);
}
#include "GoHereSecond.h" // Part of 2nd Foward Declare
void CGoHereFirst::Funct1()
{
Var = 5;
CString a;
a.Format("1st: Var = %d", Var);
AfxMessageBox(a);
m_CGoHereSecond->Funct2();
}
#include "GoHereFirst.h" // Part of 1st Foward Declare
void CGoHereSecond::Funct2()
{
CString b;
b.Format("2nd: Var = %d", m_CGoHereFirst->Var);
AfxMessageBox(b);
}

Hey all,
I have a strange problem with an exception being thrown and not caught properly. The exception is of the CDBException type and the code looks like the snippet given below. If I give an erroneous sql statement, an exception is thrown and caught, but when I leave the END_CATCH (or END_CATCH_ALL for that matter), the program crashes. This only occurs in release mode - debug mode is trapping and continuing fine. Sounds like I'm running rampage in my mem region, but I'm fairly sure I'm not...Any help on this will be mighty appriciated.
CRecordset* pRecordset = NULL;
TRY
{
BOOL bIsRecordPresent = FALSE;
//make the recordset
pRecordset = new CRecordset( &m_Database );
//open it
if (pRecordset->Open(CRecordset::snapshot, szSQLIsPresent, CRecordset::readOnly))
{
...
}
}
CATCH(CDBException, eDB)
{
char bufErr[512];
eDB->GetErrorMessage(bufErr, 512, NULL);
eDB->Delete();
//error reporting
}
CATCH(CMemoryException , e)
{
char bufErr[512];
e->GetErrorMessage(bufErr, 512, NULL);
e->Delete();
//error reporting
}
END_CATCH
Best regards
/Boris

Found it - The exception clean up of CDBException 'eDB->Delete();' throws a new exception.
Have no idea why
