Is it possible to dynamically add controls to a dialog box?

[chandrika]

Dear Members,

I want to use edit boxes to selectively view the contents of a file, is there any way to specify the number of edit boxes(usingan integer variable, say) in a dialog box at run time?

AlsoI want to update the contents of an editbox, ie add new lines to it while keeping the previous ones, but I cant seem to find a way to accomplish this...

Any assistance with these issues will be greatly appreciated

Regards

You could add the controls and make them invisible at the start, then make them visible later. All resources need to be available and they must either be connected to callback routines or have their ID's dealt with ina subclassed dialog box procedure. see http://tinyurl.com/5gqj3.

You can also add via a hook procedure. Do some searches on this board for 'adding controls' and you will get some useful info.

Dear Sir,

I searched the message boards like you suggested (I decided to tackle mymultiline problem first) and my search yielded the following subroutine:

SUBROUTINE AppendEditText(Dlg, ID, sText)
TYPE(Dialog):: Dlg
INTEGER:: ID
CHARACTER(*):: sText

CHARACTER(LEN=LEN(sText)+1):: szText
INTEGER:: hwndEdit, i

hwndEdit = GetDlgItem(Dlg%hWnd, ID)
szText=TRIM(sText)//CHAR(0)
nLength = SendMessage ( hwndEdit, WM_GETTEXTLENGTH, 0, 0 )
i = SendMessage ( hwndEdit, EM_SETSEL, nLength, nLength )
i = SendMessage ( hwndEdit, EM_REPLACESEL, 0, LOC(szText))
END SUBROUTINE AppendEditText

I am using it as follows however I cannot see anything in my editbox. I set the properties 'Multiline' and 'Want Return' under the 'styles' tab. Am I implementing it correctly? Any assistance will be greatly appreciated.

retlog = DlgInit( IDD_DIALOG9,dlg )
if ( retlog .eq. .true. ) then

name = 'Chandrika'
call AppendEditText(dlg, IDC_Edit1, name)
iret = dlgmodal(dlg)

end if

Have you tried, as it was sugested, that link? There is an API function sample:

i = ShowWindow(GetDlgItem(Dlg%hWnd,IDC_WHATEVER),SW_HIDE/SW_SHOW)

To edit multiline outputs (or whatever) I use ListBox.

Let me know, if you need help with it.
