ListView Selection help
I'm trying to get the text of a selected item in a listview control.
HWND hFileList = GetDlgItem(MainWindow->hDlg1, IDC_LIST3);
LPTSTR szText;
int i = ListView_GetSelectionMark (hFileList);
if (i == -1){
MessageBox(0, "no selction you twat!", "blabla", MB_OK);
}
else{
ListView_GetItemText (hFileList, i, 0, szText, sizeof(szText));
MessageBox(0, szText, "blabla", MB_OK);
}
The index is returned correctly, but szText is just some garbage string...
Any idea why the text of the slected item isnt output instead of garbage?
Cheers.

You need to specify a string buffer for szText, not a pointer.
TCHAR szText[ MAX_PATH ];
not
LPTSTR szText;

Arjay,
Tried that, still some garbage string is output to the MessageBox :(
Kirants,
Oops! Still the same error however :(

Issue ( probably not the reason why you are seeing the garbage ): The last parameter to GetItemText is supposed to be the no. of characters and not no. of bytes. sizeof() always gives no. of bytes. You can resolve it by passing sizeof(szText)/sizeof(szText[0])
Question. Are you by any chance trying to read this from a list control that is in another application ?

Unfortunately that doesnt solve the issue :(
No, the ListView is in a dialog based application. I am able to Add items to it perfectly.
Thanks for the help :)

What compiler are you using? VC6, VC7.1?
Are you compiling in ANSI or UNICODE?
If compiling in UNICODE on VC6, and are looking at the string in the debugger, you'll need to append a ,su in the watch window in order for a unicode string to show up.
ie.
szText,su
