How about setting the width of that column to zero?

the basic difference is the debug information will be embedded in the exe in debug build which is not possible in release build.is it suficient or are u looking for anything else.

Another difference is that debug mode can maybe work perfectly, but same code in release may crush in hundreds of places.

Debug assumes some things when nothing is said, or automatically correct some errors of intialization.
Release executes ONLY what the programmer has written. If it is not correctly written will crush.

Speed is the main difference a debug build will by default have no optimisation, this makes it easier to debug. But you can debug a release build it is just a little harder.

Hi In my program i want to use

<br />
BOOL MapAndLoad(<br />
  PSTR ImageName,<br />
  PSTR DllPath,<br />
  PLOADED_IMAGE LoadedImage,<br />
  BOOL DotDll,<br />
  BOOL ReadOnly<br />
);<br />

function in Imagehlp.h .

<br />
CPE::CPE(CString fileName, CString filePath):fileName(fileName),filePath(filePath)<br />
{       LOADED_IMAGE loi;<br />
	::MapAndLoad((LPSTR)(LPCTSTR)fileName, (LPSTR)(LPCTSTR)filePath, &loi,FALSE, TRUE);<br />
	int i = loi.NumberOfSections;<br />
        char q[50];<br />
	sprintf(q,"%d",i);<br />
	MessageBox(NULL, q,NULL,0);<br />
}<br />

When i compiled and execute it. It gives error Messagebox with value -858993460 . I changed my projects setting use multibyte character set. wchar_t to char.

But can not find solution. What is wrong with this code?
How can i fix it?

Thanks.

You did not check the return value from MapAndLoad(), nor did you call GetLastError().

I checked the return value, it is not TRUE
MapAndLoad() is not working.
I changed code because of pstr parameters.

CPE::CPE(CString fileName, CString filePath):fileName(fileName),filePath(filePath)<br />
{  <br />
	char *ch1 = strdup(fileName);<br />
	char *ch2 = strdup(filePath);<br />
	MessageBox(NULL, ch1, ch2, 0);<br />
	<br />
	PLOADED_IMAGE loi = ::ImageLoad((PSTR)ch1, (PSTR)ch2);<br />
<br />
	<br />
<br />
	BOOL b = ::MapAndLoad(ch1, ch2, loi,TRUE, TRUE);<br />
	if(b == TRUE)<br />
	{<br />
		MessageBox(NULL, "DONE", NULL, 0);<br />
	}<br />
	<br />
     ULONG i = loi->NumberOfSections;<br />
	    char q[50];<br />
	sprintf(q,"%d",i);<br />
	MessageBox(NULL, q,NULL,0);<br />
   }

fileName and filePath parameters correct (they are coming from CFileDialog) but it gives run-time error in line ULONG i = loi->NumberOfSections;
Unhandled exception at 0x76c977f2 in PEInside.exe: 0xC0000005: Access violation writing location 0x00000004.

Do you have any suggestions?

If MapAndLoad() is returning 0, why are you then proceeding to dereference loi?

sawerr wrote:

Yes.

BOOL b = ::MapAndLoad(ch1, ch2, loi, TRUE, TRUE);
if (b)
{
    CString q;
 
    q.Format("%lu", loi->NumberOfSections);
    AfxMessageBox(q);
}
else
{
    CString q;
 
    q.Format("%lu", GetLastError());
    AfxMessageBox(q);
}

Sir,
I have taken a VC++ Project as MFCAPPWIZARD(exe) and Dialog Based support. In that I have taken a picture control for that I 'import'ed some bitmap images and set one of them as default.My code performs the functionality like, for every 5 seconds the image in the picture control will be changed continuously repeating the same pictures .(for this I used SetTimer(.......))
Now I am want to give a functionality to a button, which sets the current image in the picture control as My Desktop Background.

Please send any solution or suggestion in this regard like what functions may useful or any code is already having in our codeproject.com

Apparently, you are providing full path names to the pFrom field. If you don't provide full path names, the file(s) won't go to the recycle bin.

If you need to provide full path names, you can try this - I haven't tested it:

Insure that the flags field of SHFILEOPSTRUCT does not contain the FOF_ALLOWUNDO bit.

SHFILEOPSTRUCT foStruct;
foStruct.fFlags &= (~FOF_ALLOWUNDO);

Hope that helps.
