I'm have a button on my panel and need to call FileFindFirst() to get handle of files in a folder when clicking on the button.
everthing is good at mql4, buy I want to convert my source code to mql5.
I don'k know why i can not get file_handle by click event. if I click on a button file_handle is INVALID_HANDLE. Buy if I call the function some
where else the file handle is valid.
this problem is occurred only in MT5 platform !
