If it helps any, I took a mulithreaded app and placed some intentional leaks in one of three of the threads. Everything appears fine until the app exits and the main thread is being shut down. That is where I get my notification of a leak.
Again, I'm not familiar with 3rd party leak detection tools and how they report. I usually incrementally scrutinize any changes so I know what I just changed is likely causes any reported leaks.
What was the last thing modified in the code?

It seems to me that I have missed the exact biuld, when it appears exactly. So, now I need some tool or information to find out, how it could be so. As you can imagine, in my oppinion there are no fresh reasons for leaks 
So, does someone can help?
|
|
|
|

Lets reformulate the question a bit: I know the address, that leaks. I need a tool, which can tell me (after the execution of application), which line allocates at this address. Who knows such thing?

I haven't used VLD, but i expect that i creates a global instance of an class that checks for leaks in it's destructor.
I would also expect that there hasn't been any effort to control at what point the global object is created.
I would guess that there is a global object that is being created before VLD is initialized.
When when VLD exits all memory allocated since it was initialized has been freed, it knows nothing about memory allocated before it was initialized (so it says no leaks).
Your internal is likely the same.
So, depending on what you are calling that actually generates the leak message, you may have a leak in a global that is initialized early, or you may not have a leak at all just mis-configured leak detection code.

Thanx, but I do not think so.
1) Even without VLD I'm gettint "No leaks" and then a report about leaks from internal finder
2) I do not regulate the moment, whan VLD is created. It is kind of "p'n'p" solution: I just include it, no changes to code.
Does anyone have more ideas?

I don't know about third-party leak detectors.
I do use the CRT heap debugging features in my debug builds.
This goes on top (under the (#include lines) of all my source files:
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
For leaks that still don't give file/line number info...
In the debug output for the leaks, if the number in the curly braces is the same every time
you can add a breakpoint to break when those allocations occur.

Thank you for the information, it is very interesting, but the problem again. All the time I'm getting problem on allocations 59 and 60.
{60} normal block at 0x02721790, 12 bytes long.<br />
Data: < r r > 90 17 72 02 90 17 72 02 CD CD CD CD <br />
{59} normal block at 0x027217D0, 44 bytes long.<br />
Data: <|hm am am r > 7C 68 6D 02 80 61 6D 02 88 61 6D 02 10 1B 72 02 <br />
Object dump complete.<br />
but _CrtSetBreakAlloc(60); results in no break. Why can it be? I'm using VC++ 6, but there are no reasons to assume that it doesn't support this function.

I want to download the latest platform SDK for visual c++ based development. If I use google to locate it, I am being taken to a page at Microsoft which says Windows 2003 server sdk. If I search MS for SDK, there are plenty of results and I am confused. Can someone give me a link where I could download the latest platform SDK? Thanks.
Sorry if it is posted twice. There was error, when I attempted previously. I will delete one, if it is posted twice.

Windows Server 2003 R2 sdk
that is to the best of my knowneldge is the latest sdk for vc++ developers
p.s its name is a bit miss leading but thats the one
|
|
|
|
|
If you're using VS05, the latest & greatest SDK is now called the Windows SDK[^].

looks like i need to upgrade my SDK 
thanks

Ive looked around on getting inputs from the LPT port on windows xp, apparantly I need a dll called inpout32.dll. I have that, however I wonder how I should "include" the file? So that i can use the code described on http://www.ctv.es/pckits/tutorial.html#ppro and its functions
Ive looked around alot on codeproject, and google around 50 times, but not found how to get it to work...
any ideas?
Im open to other methods too, but nothing too advanced.
PS, im in win32console with mfc on winxp, i will only be using lpt inputs, two of them.
thanks!

I've developed a program that performs some mathematical operations and then exports the results into a csv file to be opened with Excel.
To export the results I used a while loop with incremental values and that's fine but now I'd like to save (and read) some results in (or from) very specific locations (e.g. 6th case of the 2nd row).
I am using C++ and the Win32 Console application in VS2005.
Does anybody know how to do that?
Many thanks for your help.

Without also writing to the first row, and the other five cases of the second row?

Correct!
Is it possible to read and write to and from very specific locations leving the rest unchanged?
I will be happy only when I will have FULL contol over this nasty language!

Probably, but I would find it a lot easier to read the file into some sort of data structure, make the necessary changes, and write the data structure back to disk.

Hi all,
I am transferring to .NET 2003 to .NET 2005 now. I have one application made in Visual C++.NET 2003. It is compiling fine in .NET 2005 but it gives one run time error at ShowDialog() function of OpenFileDialog Class object. Error is
"An unhandled exception of type 'System.Threading.ThreadStateException' occurred in System.Windows.Forms.dll
Additional information: Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process."
Can I know what is wrong with this? And how can I solve this problem.
Thanks in advance,
Priyank

This should be posted on the Managed C++/CLI board.
I'm not sure what threads have to do with using the OpenFileDialog, but the error message is
pretty descriptive - it even states how to fix it.
Which version of ShowDialog() are you using?

I think Mike's onto something here; the error message is describing exactly what's wrong. See here[^] for more details.

I am using Visual Studio 2005, with Visual C++, and have generated a single docuemnt project with mainframe and childview for MFC.
I want to display parts of an image that the program loads from a bitmap file, on a grid pattern as produced by CGrid class in Grid.h and Grid.cpp.
When I use the StretchBlt function, the program asks for a HDC!!!!
I have not found litterature or samples for the use of that device context.
Would you know of a solution?
Thanks for any help....
Here is a possible code section for my function. With it, I can enter a string but not the image. It creates a CDC* but not a HDC. How should I code the HDC?????
void CGrid::FillCell(int r, int c, CString val, COLORREF brushColor, CImage m_Image)
{
CWnd* pWnd = AfxGetMainWnd();
CDC* pDC = pWnd->GetDC();
// pDC->BitBlt(0,0,20,20,pDC,0,0,SRCCOPY);
CBrush* pBrush;
pBrush = new CBrush (brushColor);
pDC->FillRect (mGrid[r][c],pBrush );
delete pBrush;
pDC->SetBkMode (TRANSPARENT);
pDC->SetTextColor (mStringColor);
pDC->DrawText(val,-1,mGrid[r][c],
DT_SINGLELINE |
DT_CENTER |
DT_VCENTER
);
// m_Image.StretchBlt(pDC,mGrid[r][c].TopLeft().x,mGrid[r][c].TopLeft().y,mGrid[r][c].Width(),mGrid[r][c].Height(),mGrid[r][c].TopLeft().x,mGrid[r][c].TopLeft().y,mGrid[r][c].Width(),mGrid[r][c].Height(),SRCCOPY);
// pDC->StretchBlt(mGrid[r][c].TopLeft().x,mGrid[r][c].TopLeft().y,mGrid[r][c].Width(),mGrid[r][c].Height(),m_Image,mGrid[r][c].TopLeft().x,mGrid[r][c].TopLeft().y,mGrid[r][c].Width(),mGrid[r][c].Height(),SRCCOPY);
pWnd->ReleaseDC(pDC);
}

Is the destination grid pattern on a window?
If so, then your code should work. Instead of trying to pass "pDC" as the destination DC,
pass "*pDC". This forces the compiler to use the CDC (HDC) cast operator to extract the HDC from
the CDC object. CDC is a C++ wrapper for an HDC.
You may need to get a DC for the window the grid is on, not the main frame window. The main
frame window is covered by a child view window. The view window is the one you want the DC for,
or whichever window you want to draw the image on.

For starters, if you are trying to draw on on the view, you are getting a DC for the wrong window. Your getting a DC for the main frame window. From within you view class code, just use "this" since it is a pointer to the view/wnd
CDC* pDC=this->GetDC();
// or
CDC* pDC=GetDC();
Next, make sure the drawing code is in or called from the views OnDraw handler since anytime you drag another window over the view it will erase your drawing like an eraser. The OnDraw will get called and if your drawing code is not there to refresh the image, nothing will happen.
Next make sure you have the correct coordinate system for your drawing. The default mapping mode is MM_TEXT (y-axis positive as it goes down) all other mapping modes like MM_HIMETRIC, MM_HIENGLISH, etc... have the y-axis negative as it goes down. MM_ANISOTROPIC and MM_ISOTROPIC allow you to set the y-axis orientation. I've spent many an hour chasing my tail because my y-axis orientation was incorrect.
// The handle is a member of CDC. To access it use the arrow operator
pDC->m_hDC
// Something like
m_Image.StretchBlt(pDC->m_hDC, etc...
I hope that helps

Hi. I've been quite a while out of C++, wasn't expert before either. But right now, I got a really strange problem with strcpy. Maybe somebody can help? : )
<br />
char cBuffer[256];<br />
char cTemp[260];<br />
<br />
<br />
char ch = cBuffer[0];
strcpy(cTemp, "R");
strcpy(cTemp, &ch);
So what should I do to put ch in cTemp???
Thank you in advance...
