If you want MRU files list, just create an SDI/MDI application using MFC AppWizard.
This functionality will be implemented by default in framework, and nomore sweat for you.

Perhaps you should use SUBSTRING function:
SELECT SUBSTRING(name, 1, 3) FROM table1 ...
Alternatively you can obtain the substring in C++ after you get the entire name from database.

|
|
select SUBSTRING(name, 1, 3) from table1 where fname="name"

Hi all,
Im creating a .dll using ATL. Recently I have got to add the file operation part to it but as soon as I did it, it started to throw error saying :
" Drawing Assertion failed
Program : c:\windows........
File : fprintf.c
Line :55
Expression : (str!= NULL)
.................. "
This is the part of code which I'm using. It works well as far as I'll keep
fprintf(......);
statement away. But as soon as I included that its throwing error.
<br />
STDMETHODIMP CYourClass::YourATLMethod(BSTR Filepath, BSTR* ReturnString)<br />
{<br />
_bstr_t LbstrFilepath = Filepath;<br />
<br />
XMP_VersionInfo version;<br />
SXMPMeta::GetVersionInfo ( &version );<br />
FILE * sLogFile=fopen( "XMPLog.txt", "wb" ); ;<br />
fprintf ( sLogFile, "Version : %s\n" , version.message );
please guide me. where and why it is throwing error. What I'm supposed to get rid of this.
Regards,
Arun

Is sLogFile a valid file pointer? Per the assertion, it is NULL.
What type is version.message?

As per me yes it is. Is there something I need to takecare about that??? Its just a File pointer. Its creating empty file but while coming to "fprintf" it'll throw the error.
version.message is a string.
I have got lots of "fprintf" statement in the module and I checked with all of them one by one its throwing the same error as above.
I'm creatin .dll using ATL in VS 2005.

Arun

Then you should probably be using the c_str() method.

No I'm not making use of c_str().
Please let me know if it is required to take someother way to get this thing done. If possible with a sample piece of code.
Thanking you
Arun

The %s directive makes printf() and friends expect a string pointer on the stack. If you pass an object, such as std::string, you'll give it "garbage". If you give it a pointer to the internal string buffer instead, it'll work.
std::string str;
const char* pInternalBuffer = str.c_str();
printf("A string: %s\n", pInternalBuffer);

Thanks. I tried it but didnt solve the problem. I refered in some other atricles and I think it might happening because of default debugging output directory.
What do you think???

Have you tried:
fprintf(sLogFile, "Version : %s\n", version.message.c_str());

Thanks. I tried that too but didn't work either.

The problem, as I mentioned here, is that the FILE* passed to fprintf() is NULL. That's what the assertion is telling you.

But it is creating the file in the "fopen" statement.
Ok incase as you said if it is doing so then what is the solution for that. What I'm supposed to do on that case.

I'm out of ideas at this point. You might try setting a breakpoint on the fprintf() statement and verify the value of sLogFile.

I'm writing dll and using it in C# so I cant put the break point. That is main problem to trace out.
