I have not looked at these classes but why don't you just add a handler and/or a member variable for your purpose?

Sounds like SHGetPathFromIDList().

Hi Mr.Crow,
yes i tried it with this function, but i didn't manage to get the file path, name and extension.
Could you perhaps explain me how to use this function in the right way?
Best regards
Croc

Assuming you have a valid IDL pointer:
LPITEMIDLIST idl;
TCHAR szPath[MAX_PATH];
SHGetPathFromIDList(idl, szPath);

From where do you want to get this "dynamically generated URL"
and where do you get the hard code URL from?
Somethings seem HARD to do, until we know how to do them.

Hello I have a little big problem that drive me crazy for 3 hours.
I have a function that browse the content of a folder (with subfolders).
After that operation is done I want to delete the folder. The function is recursive.
All the files in the route folder are deleted ok. But I cannot delete the subFolders and their content.
I use this code for retrieve information about files and folders:
WIN32_FIND_DATA FindFileData;
HANDLE hFind=INVALID_HANDLE_VALUE;
hFind= FindFirstFile(aux,&FindFileData);
FindNextFile(hFind, &FindFileData);
I guess that it is us
How can I remove the file/folder in use tag?
I tried with
delete &FindFileData it doesn't work. There must be a way out there ...
I tried to delete the folder without browse it first and it works fine.
The weird thing is that I can delete the files that are in the root.

|
|
|
|
Did you use FindClose(hFind) ?
|
|
|
|
|
Why don't you use
DeleteFile(FindFileData.cFileName); ?

Can you use of _rmdir or SHFileOperation without this code?
|
|
|
|
|
|

I used this to erased a folder and it works
SHFILEOPSTRUCT op;
op.pFrom = szStoreFolder;
op.wFunc = FO_DELETE;
op.fFlags = FOF_SILENT | FOF_NOCONFIRMATION;
op.fAnyOperationsAborted = false;
op.hNameMappings = NULL;
SHFileOperation(&op);
only if you do not have the files in that folder in used...
if you have that you should FindClose(handleFile) if you used previous a function that searched for file in that folder

I am capturing image and saving that to a file. it is working fine. But one of other requirement is when user presses clt+alt+del, i should be able to do that (saving the image in to a bitmap file). But bitblt is failing when i press ctl+alt+del. it is returing zero.
Any suggestions ?
Thanks, Subramanyeswari

The above line should be
bRet = BitBlt(hdcOld,0,0,width,height,hdcMem,0,0,SRCCOPY);

Does hdcOld support BitBlt? You may check it with GetDeviceCaps.
