Hi all,

I'm looking for a function that can delete files by means of a wild card.

Is there such a function

If so, can anyone please provide some more information

Many Thanks in advance

I do not think that there is a standard Win32 API function do to that. You would need to enumerate items using the wildcard and then delete matching items one by one.

Peace!

Use SHFileOperation().

Hi David, I have tried the following:

SHFILEOPSTRUCT wildcards;
wildcards.wFunc = FO_DELETE;
wildcards.hwnd=NULL;
wildcards.pFrom=(LPCTSTR)lpUpDownFiles[first].szUpFName;
wildcards.fFlags=FOF_FILESONLY;
SHFileOperation(wildcards);

But get the following error:
Error 7 error C2664: 'SHFileOperationA' : cannot convert parameter 1 from 'SHFILEOPSTRUCT' to 'LPSHFILEOPSTRUCTA'

Can you please help?

Many Thanks

The compiler is telling you the problem. SHFileOperation() is expectnng a pointer (to a SHFILEOPSTRUCT).

My bad .... OMG | :OMG:

LPSHFILEOPSTRUCT lpFileOp;						
lpFileOp->wFunc = FO_DELETE;
lpFileOp->hwnd=NULL;
lpFileOp->pFrom=(LPCTSTR)lpUpDownFiles[first].szUpFName;
lpFileOp->fFlags=FOF_FILESONLY;
SHFileOperation(lpFileOp);

No memory has been assigned to lpFileOp. Why aren't you using:

SHFILEOPSTRUCT lpFileOp = {0};
lpFileOp.wFunc  = FO_DELETE;
lpFileOp.pFrom  = (LPCTSTR)lpUpDownFiles[first].szUpFName;
lpFileOp.fFlags = FOF_FILESONLY;
SHFileOperation(&lpFileOp);

Hi David ... What would I do in the following instance:

Run-Time Check Failure #3 - The variable 'lpFileOp' is being used without being initialized.

Ok ... sorry but I think I got it OMG | :OMG:

SHFILEOPSTRUCT shFileOp;			
shFileOp.wFunc = FO_DELETE;
shFileOp.hwnd=NULL;
shFileOp.pFrom=(LPCTSTR)lpUpDownFiles[first].szUpFName;
shFileOp.pTo=NULL;
shFileOp.fFlags=FOF_FILESONLY;
shFileOp.lpszProgressTitle=(LPCTSTR)"Delete Files";
SHFileOperation(&shFileOp);

Thanks ...

Can we find out the size of a structure without using sizeof function?
I have tried to write a macro passing the name of the structure as a parameter, but it did not work as expected!! Is there anyother way to do this?
Please provide your valuable suggestions and code(if possible).....

Even sizeof usage is hazardous on Win32 structures.

Since we are working on generating metadata about a structure by supplying the name of the structure, and getting its size during run time!!

This makes no sense. How does it answer the question, "Why is sizeof usage hazardous on Win32 structures?"
