Pointer returning problem

Craazer · 2003-03-27T19:08:25

Usualy returning pointer isn''t big deal but there is shometing funky what messups returning. If u could check the code below please. LPCTSTR GetFilename() { OPENFILENAME browsedfile; // code // ... if(!GetOpenFileName(&browsedfile)) return 0; // function returns succes and all the variables are correct but browsedfile.lpstrFileTitle is odd... even it holds the right string // pointer seems to be ok cout<<browsedfile.lpstrFileTitle<<endl; // string was printed succesfully // if this code wasn''t comment returned pointer would be good so it looks like GetOpenFilename() does shometing wierd to this variable? // browsedfile.lpstrFileTitle = "A test string"; // returns invalid pointer return browsedfile.lpstrFileTitle; } So does anyone have any idea what might cause this? Did u see the problem?

Just don''t forget to deallocate that string somewhere. Probably in the function that''s calling GetFilename.

Another approach could be to use std::string objects and pass by reference or value.

How about making the OPENFILENAME struct static?
You won''t have to deallocate anything afterwards, but you''d better make sure you''re done with the string before calling GetFilename() again (it will be overwritten).
