Yep you are right. Actually that file path not written on the application. It is find from the application and I've just use it. Smile | :)

Those are from C right, not C++ functions. Is it better to mix up them. Actually I don't like to do it.

Have you considered atoi()?

Use of SetWindowsHookEx detectd as spyware

Hi
I am creating a MAC OS Type dock bar application (Similar to Object dock) on Windows for one of our customer. I need to implement auto hiding feature in dock bar (similar to auto hide feature in windows task bar). As per my knowledge only possible way to implement auto hide is to use SetWindowsHookEx API to create System hook for mouse event.

Now the problem is that I heard that all application that is using SetWindowsHookEx api are detected as spyware by most anti virus and other tools.

Can some one suggest how can I use SetWindowsHookEx safely or any other way to implement auto hide feature in these kinds of applications.

I have used the SetWindowsHookEx() in some application. But haven't got the warning from the antivirus yet( tried in norton ).

How ever try putting the SetWindowsHookEx in a dll. I.e create a function in the dll and eport it. inside that function call the SetWindowsHookEx.

why rename would fail sometimes?

Hello everyone.In my program,I want to change a file's content,so I create a create file to copy data from source file and write new data,too.
When all file reading and writing completed,I want to delete the source file and rename the temp file to the source file name.If the source file path is sourcePath,and the temp file path is tempPath,my codes look like following:
if(remove(sourcePath)==0)//sourcePath is the full path of the source file
rename(tempPath,sourcePath);
Of course,the source and temp file are in the same directory.

But it is strange that,if i separate the codes as a short test console project,it works well!
Someones would like to tell me why?
Thanks.

GOOD LUCK

If rename() is failing, check errno.

Unwanted control characters in a CString

Hello. I'm trying to parse some web data with the following code. It's going reasonably well, but I seem to get control characters (little squares) in the CString, making the parsing more difficult. If they're on the end I can use Trim() to remove them, but if they're in the middle it's more problematic. Since I can't represent them with the keyboard it's difficult to use the Span functions. Does anyone have any suggestions? Thank you.

hr = pHTMLDocument2->get_body( &pElem );

ScrapeFuturesSettlementData( strInnerText );
}
pHTMLDocument2->Release();

If you are using MFC, and your dialog template has a static control on it, check out CStatic::SetBitmap(). Otherwise, if you want the image to be the dialog's background, see here.

Adding WM_VSCROLL to message handler for slider control in VS 2005 with C++ and MFC

GrizzlyDoug4-Dec-07 8:04

In trying to add WM_VSCROLL to message handler for slider control in VS 2005 with C++ and MFC, I ran into problem that the slider only supports 4 NMXXXXXXXXX messages or events. What wizards and tabs/menu selections do I choose to get to a place where I can add the WM_VSCROLL message handler to handle messages for the slider so I can get access to it's current value. This is probably an easy thing to do, but it seems like it has gotten more difficult since access to all the messages has been limited, leaving only a very small subset.

The messages are sent to the trackbar control's parent by default.

You could right click the parent window class in the class view window,
choose properties, select the messages tab in the properties window,
and add the WM_VSCROLL handler there.

GDI+ samples and malloc/free [modified]

bob169724-Dec-07 7:16

In the MSDN source code for some GDI+ methods, the authors use malloc and free. Why would they do this if RectF is a class? Is this a hint that it is merely the equivalent to a struct with the ctor and dtor doing nada? Should we follow this convention or use new/delete instead?

Here's an example for GetRegionScans()...

VOID Example_GetRegionScansRect(HDC hdc)
{
   Graphics graphics(hdc);
   SolidBrush solidBrush(Color(255, 255, 0, 0));
   Pen pen(Color(255, 0, 0, 0));
   GraphicsPath path;
   Matrix matrix;
   Rect* rects = NULL;
   INT count = 0;  

   // Create a region from a path.
   path.AddEllipse(10, 10, 50, 300);
   Region pathRegion(&path);    
   graphics.FillRegion(&solidBrush, &pathRegion);

   // Get the rectangles.
   graphics.GetTransform(&matrix);
   count = pathRegion.GetRegionScansCount(&matrix);
   rects = (Rect*)malloc(count*sizeof(Rect));
   pathRegion.GetRegionScans(&matrix, rects, &count);  

   // Draw the rectangles.
   for(INT j = 0; j < count; ++j)
      graphics.DrawRectangle(&pen, rects[j]);

   free(rects);
}

Does its constructor/destructor do anything?

Keep in mind that just because it's an MSDN sample, that does not imply it's also perfect code. Folks that supply samples to MSDN are not infallible. MSDN does provide lots of great code, some of which can be used unaltered, but it should still be scrutinized regardless.

I'm not sure the GDI+ source code is available for inspection (except the declaration files of course)

I understand what your saying. I was scrutinizing it and I couldn't determine why they were doing it. I thought I'd post the question to see if it made sense to anybody and if they could explain what benefits the author is realizing here or if the code is flawed.

Thanks for the input.
