Select all text in edit field

>Since the PowerBASIC functions doesn't have statements to handle selections

This would be a really good place for some macros...

MACRO  Edit_SelectAll (hEdit)    = SendMessage(hEdit, %EM_SetSel, -1, 0)
MACRO  Edit_UnselectAll (hEdit) = SendMessage(hEdit, %EM_SetSel, 0, -1)

That sure seems a lot easier to remember, no?

Brian,

These two lines do what you ask - select all, unselect all.

SendMessage(hEdit, %EM_SetSel, -1, 0)       '-1,0 unselects all
SendMessage(hEdit, %EM_SetSel, 0, -1)       '0,-1 selects all

Since the PowerBASIC functions doesn't have statements to handle selections, you have to use the Windows messages. "SendMessage".

Or, you can use the PowerBASIC "Control Send" to send the same messages.

Control Send hDlg, %ID_Edit, %EM_SetSel, -1, 0
Control Send hDlg, %ID_Edit, %EM_SetSel, 0, -1

The hDlg is the dialog handle, %ID_Edit is the edit control ID, and %EM_SetSel is the message being sent. The -1,0 and 0,-1 pairs are the wParam and lParam arguments to the message you're sending.

Here's an online, compilable source code example.

Brian,

Look at the link I posted...EM_SETSEL is the message you send to an edit control to select/unselect text in an edit field.

Clear & Select All

I didn't see or understand what in those previous messages would help me do Clear and Select All

Could someone explain, it's been a while since I have used PowerBASIC.
