NB: in reference to the answer above the MSVC runtime function _stat() does a GetFileAttributes and a bunch of other stuff

use PathFileExists() API.
|
|
|
|
|
The simplest way to check if a file is exists is to open it with a call to CreateFile()

There's also _access(), which is just a wrapper around GetFileAttributes().

Hello,
When I am debugging the source code,I got "Debug Assertion Failed" as a heading and the text which shown in big letters.
When I see the output i got the following messages.

Please if anyone identifies the error let me know.

Can you show your code that generates this error(dont need to post full code).
|
|
|
|
|
void FileNameCreate(LPTSTR szPathBuffer, LPTSTR sPath, LPTSTR sFile, LPTSTR sExt)
{
char szTmpPathBuffer[MAX];
char *sTmpPath= NULL;
char *sTmpFile = NULL;
char sTmpExt[LEN_MAX];
try
{
sTmpPath = new char[LEN_MAX];
sTmpFile = new char[LEN_MAX];
TrUnicodeToChar(sPath,sTmpPath);
TrUnicodeToChar(sFile,sTmpFile);
TrUnicodeToChar(sExt,sTmpExt);
FileNameCreate(szTmpPathBuffer, sTmpPath, sTmpFile, sTmpExt,sizeof(szTmpPathBuffer));
TrCharToUnicode(szTmpPathBuffer,szPathBuffer);
delete [] sTmpPath;
delete [] sTmpFile;
}
catch(bad_alloc)
{
if(sTmpPath!=NULL)
delete [] sTmpPath;
if(sTmpFile!=NULL)
delete [] sTmpFile;
}
}
Error message has been occurred only in the text is shown in big letters.

The code listing is incomplete (missing information on sTmpExt), but my guess is that TrCharToUnicode(...) is overwriting the memory pointed to by szPathBuffer because it is not being told the size of the memory (in TCHARs) being pointed to by szPathBuffer.
Peace!

char to unicode means also that you need twice the amount of bits to store the output string.

Also I got the popup message also:

Hi,
Thanks a lot for your response. I have added the code snippet which I got debug assertion failed error shown in bold letter:
============================================================
#define MAX 520
#define LEN_MAX 500
void FileNameCreate(LPTSTR szPathBuffer, LPTSTR sPath, LPTSTR sFile, LPTSTR sExt)
{
char szTmpPathBuffer[MAX];
char *sTmpPath= NULL;
char *sTmpFile = NULL;
char sTmpExt[LEN_MAX];
try
{
sTmpPath = new char[LEN_MAX];
sTmpFile = new char[LEN_MAX];
TrUnicodeToChar(sPath,sTmpPath);
TrUnicodeToChar(sFile,sTmpFile);
TrUnicodeToChar(sExt,sTmpExt);
FileNameCreate(szTmpPathBuffer, sTmpPath, sTmpFile, sTmpExt,sizeof(szTmpPathBuffer));
TrCharToUnicode(szTmpPathBuffer,szPathBuffer);
delete [] sTmpPath;
delete [] sTmpFile; }
=========================================================
LPTSTR TrCharToUnicode(char *CharBuffer, LPTSTR csBuffer, size_t uNbChar)
{
USES_CONVERSION;
if(CharBuffer == NULL)
return NULL;
else
{
if (uNbChar == 0)
uNbChar = strlen (CharBuffer)+1;
MultiByteToWideChar(CP_ACP, 0, CharBuffer, uNbChar, csBuffer, uNbChar);
return csBuffer;
}
}
=======================================================
Please give me some input to solve this issue.
Thanks in advance.

Hai,
Thanks for your response. I got the following errors:
1. Windows has triggered a breakpoint in omc.exe.
This may be due to a corruption of the heap, and indicates a bug in omc.exe or any of the DLLs it has loaded.
The output window may have more diagnostic information
This is shown in the output window of VS2005
2. Run-Time Check Failure #2 - Stack around the variable 'sStr' was corrupted.
This one is display as popup window

Now I got the following error message:
First-chance exception at 0x7c81eb33 in omc.exe: Microsoft C++ exception: CFileException at memory location 0x0012bdd4..
CFile exception: badPath, File d:\omc\omc610~1\omcpro~1\targprod\afr100\customer.dbs\test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test5test523.cdb, OS error information = 3.First-chance exception at 0x7c81eb33 in omc.exe: Microsoft C++ exception: CFileException at memory location 0x0012b0f4..

The thread 'Win32 Thread' (0xc1c) has exited with code 0 (0x0).
LockDataBase : The state of the object is signaled
The problem is that if I save the file name in 200chars it is accepting. But If i save the file name as 202 chars it will throw an exception. I have given the variable size upto 2000.
Please give me your suggestions to solve this issue.

The errors you show are (CFile) exceptions. Does the path shown in the exception not mean anything to you?
For the fourth time, what line of what file is asserting?

It shows the following error messages:

From here you should be able to look at the stack frame to see how code execution got to line 877. It looks to be a string-related object.

hi,
i have an image control 100x100 (icon style), i want to desplay an image of 32x32 stretched in to that control. how to do that ?
Thanks & Regards
|
|
|
|
|
I have seen a number of different "image" controls, some come with Visual Studio, some come from third parties. Without knowing which particular image control you are using I doubt anyone can answer the question.
|
|
|
|
|
i am using image control aavilable with visual studio.actually i want to stretch an HICON and i missed that in my question.
Thanks & Regards
|
|
|
|
|
Please refer StretchBlt[^] function.
Best Regards,
Suman
|
|
|
|
|
One thing about StretchBlt when use of it, it decreases quality of image.
|
|
|
|
|
well, duh! when you stretch a 32x32 image to a 100x100 image you will always loose quality.
