What is it? What are you doing that causes this? Is the dialog modeless or modal?

Tell us what the error is, then we might be able to help you. An assertion shows up to tell you that something went wrong. There is in general an indication of what went wrong. We cannot guess from what it is.
A tip that will help you a lot: learn to use your debugger ! You cannot even imagine how helpfull it is once you feel confortable with it. You can use the callstack to see from which function (of yours) the problem could come.

If you see a system dialog box with Retry or Break button, then click on that button, and then go to Call Stack panel (from menu: Debug --> Windows --> Call Stack) and see the history of last functions that were called before the error. This information can be useful.

i dont understand my dialob boxes are modal dialog boxes
Please mail me

When you see the Debug Assertion Failed dialog box (displayed by system, not yours), then click Retry or Break buttons and try to get more information regarding the error, examining the line where the error occurred, and perhaps analyzing the Call Stack.

when i click on retry it will display a message but it will not tel me any problem as it tel that if i am in middle of program i will lost some information
Please mail me

Can you be more specific ( of course i guess but not sure do you create dialog in this option)

If you have the screen coordinates of the pointer, then convert them to values relative to your bitmap control:
CPoint p = ...
m_cMyPicture.ScreenToClient(p);
Then probably you have to take into account the scroll position:
p += CSize(m_cMyPicture.GetScrollPos(SB_HORZ), m_cMyPicture.GetScrollPos(SB_VERT));
This is just my guess. Hope it helps.

Hi all..
I've been stuck for a long time in this problem. It seems very easy to convert CString to a const char * or char * in VC++, but it really does not work for embedded VC++. My code is simply trying to open a file, using fopen with file path taken from CFileDialog GetPathName().
<br />
CFileDialog dlg (TRUE, _T("maf"), NULL, OFN_HIDEREADONLY | OFN_FILEMUSTEXIST | OFN_EXPLORER, szFilters);<br />
if (IDOK == dlg.DoModal()) {<br />
CString __filepath = dlg.GetPathName();<br />
file = fopen(__filepath, "rb");<br />
}<br />
I've tried to read each single character from CString (by iteratively using GetAt() function) as follows
<br />
CString __filepath;<br />
__filepath = dlg.GetPathName();<br />
int x = __filepath.GetLength();<br />
char *filename;<br />
filename = new char [x];<br />
for (int i=0;i<x;i++) {<br />
filename[i] = (char)__filepath.GetAt(i);<br />
}<br />
But it does not work for UNICODE text.
Help me..

Maybe you should use Unicode character type (wchar_t) instead of char?
const wchar_t * filename = __filepath;
Or do you need a conversion from Unicode to ANSI?

Thank you for your suggest, Viorel. But when I compile the code, this error still occurs:
<br />
error C2664: 'fopen' : cannot convert parameter 1 from 'const unsigned short *' to 'const char *'<br />
I also tried using TCHAR as Milton suggest, the error becomes
<br />
error C2664: 'fopen' : cannot convert parameter 1 from 'unsigned short *' to 'const char *'<br />

From the first error messages it seems that your application is actually non-Unicode. See the project properties in order to check this (General --> Character Set). The solution with TCHAR should work in both cases, so the second error message is strange.

Actually in order to work in both cases, you should use _tfopen instead of fopen and _wfopen. Instead of char or wchar_t, use TCHAR. Define literal strings with _T("...") macro.

CString __filepath;<br />
__filepath = dlg.GetPathName();<br />
int x = __filepath.GetLength();<br />
char *filename;<br />
filename = new char [x];<br />
for (int i=0;i<x;i++) {<br />
filename[i] = (char)__filepath.GetAt(i);<br />
}
try the above code by replacing all char with TCHAR
ie char *filename; would be TCHAR *filename;<br />
filename = new char [x]; would be filename = new TCHAR [x]; and <br />
filename[i] = (char)__filepath.GetAt(i); would be filename[i] = (TCHAR)__filepath.GetAt(i);

I fu running in UNICODE, the CString converts all data assigned to it to UNICODE.
use 'W2A' macro to convert UNICODE to ASCII..
i hope that helps u out!

why u want to use char*. If u use TCHAR*..the problem will be solved..

This is not a good way.. Use _tcscpy instead

I've tried this way:
<br />
char *filename;<br />
filename = new char [x];<br />
_tcscpy(filename, __filepath);<br />
And when I compile the code, this error occurs:
<br />
error C2664: 'wcscpy' : cannot convert parameter 1 from 'char *' to 'unsigned short *'<br />

u try this way
TCHAR *filename;
filename = new TCHAR[x];
_tcscpy(filename, __filepath);

With Unicode, use wchar_t instead.
