Changing the Style of the TextBox

[Anand Kumar]

I have designed a dialog box using DDT. This dialog contains a multiline text box and an option button for Text alignment (Left, Right And centre). Can anyone give me suggestions as to change the style of the textbox.

Currently I am killing the textbox using "Control Kill" and then creating the new text box using "Control Add" with the modified properties. Is there some other way to do it.

Take a look in the source code Forum, seems someone posted such code before...

In general terms:

Some control styles are dynamically adjustable (use GetWindowLong() and SetWindowLong() with the %GWL_STYLE flag), but other styles are only able to be set at control creation time.

For styles that fit the latter case, your approach of destroying and recreating the control is the only possible method.

In summary: the technique used depends on the style bits you want to change.

If to beleive books, it's not possible to change ES_CENTER / ES_LEFT / ES_RIGHT after creation.

Unless you create your own custom edit box by super-classing the standard Windows edit control, and take appropriate action when the WM_STYLECHANGED message is received.
