Showing file in edit control
-
Hi!! I have an mfc sdi application. I have a dialog in which , i had put a text box. I want to open some file(text file), entered by user( in another EDIT CONTROL). I want that the Edit Control(for displaying file) to remain invisible, until the user clicks on SHOW FILE BUTTON. Which function should, I use for opening it?? How to do this at button_click?? "If you change then change for the good."

I think you could: Open the dialog editor, and in it, set the
Visibleproperty of the Second edit toFALSE. Then on button-click, Open the file using:CFile file; file.Open("filename.txt",CFile::modeRead | CFile::modeNoTruncate); int length = file.GetLength(); char* p = new char[length+1]; memset(p,0,length+1); file.Read(p,length); file.Close(); m_Edit2.SetWindowText(p); delete[] p; m_Edit2.ShowWindow(SW_SHOW);etc. this is this. -

Well, you are probably right, which is why I wrote
...etcas I meant to give the user an idea. I would be surprised to see code like this used as-is. this is this.khan++ wrote:

don't ! there are so many beginners asking here that they probably think one could give them a full working code...
