TAB Stop question

[Michael K. Dealey]

Ok,

Thanks guys. I knew how to set a default at start-up but was wanting it to default to 'no selection' each time through the process. However, maybe that's not possible. And when I think about it, I can't really think of any other program that acts that way.

Setting a default solves the keyboard navigation problem.

Thanks.

-Michael.

I think yo unset all radio's?
WM_TABSTOP is removed from not-selected radio's by Windows.
You may want to force this style for the first or have a default radiobutton (which is selected)

See the remarks in the help file for the CONTROL ADD OPTION statement and for CONTROL SET OPTION statement
Use Control Set Option to set the option buttons.

Your code works ok with a couple of small changes..

        CASE %WM_INITDIALOG
          CONTROL POST CBHNDL, %IDC_CLEAR, %BM_CLICK, 0, 0  ' Initialize controls
..
                CASE %IDC_CLEAR
                    IF CBCTLMSG = %BN_CLICKED THEN
                        CONTROL SET OPTION  hDlg, %IDC_OPT_TV, %IDC_OPT_TV, %IDC_OPT_FM   ' set the Option Buttons.
                        CONTROL SET OPTION  hDlg, %IDC_OPT_LB, %IDC_OPT_LB, %IDC_OPT_ME   '

If you have a lot of controls to reset at the same time it is useful to ensure that you create them with contiguous IDs,
then you can deal with them in a loop, starting with the lowest ID and upping it on each iteration. Something like:

FOR ID = 0 TO Total
  Control Set Text CbHndl, %IDC_TEXTBOX1 + ID, ""
NEXT

I hardly ever write GUI apps so this is probably a very simple thing to solve but I can't figure it out.

If you run this example, using the TAB key on the first run will cycle through the TEXTBOX, OPTION BUTTON and COMMAND BUTTON sections as expected, but once I click the CLEAR button (and reset the fields), Using TAB will go from the TEXTBOX directly to the Command Buttons--skipping the OPTION BUTTON sections. I can't figure out why (you can just type anything in the TextBox for now-or leave it blank).

I'm porting this from a PBCC app and the usual operation is that the program gets a batch number from the user, reads some stuff from a file and 'does its thing' and then resets for the next batch number--until the user quits.

I feel like this is due to something really simple like the placement of my
'%WS_' styles or the way I'm clearing the form in the CALLBACK.

By the way, is there a better way to reset everything on the form other than the way I'm doing it?

Thanks.
