I'm trying to use input from a text edit box to delete a file. The input from the textbox will be the file location and the delete button will use DeleteFile() to delete the file.

Do you know what I mean?

Yes. We understand what you mean. But where do you have the problem?

Yes. We understand what you mean. But where do you have the problem?

I want to use the text that was put in the textbox(the file location) to be used in the DeleteFile function.

DeleteFile(FileName)

In FileName I want the text that the user input to be used. Just like I would use cin.

Use GetWindowText to copy the text in the edit box, and call DeleteFile for that text.

Thanks a lot man.

"The GetWindowText function copies the text of the specified window's title bar"

Thats not what I want.

If you read further it says that if it is a control it copies the text of the control.

Okay, Im still confused. Can anyone else help?

Okay then. Try sending the EM_GETLINE Message. That surely ought to work.

How about this :

len = GetWindowTextLength(GetDlgItem(yourwindowhwnd, yourtextboxtID));
if(len > 0)
{
int i;
char* buf;
buf = (char*)GlobalAlloc(GPTR, len + 1);
GetDlgItemText(yourwindowhwnd, yourtextboxID, buf, len + 1);

string filename = buf;
GlobalFree((HANDLE)buf);
}
