Text Alignment

[Astro]

Hi,

If you build this code (Windows), the text in the text box is centered. How do I set it to left align? The code that makes it centered is in the routine for WM_PAINT.

The text box is drawn in the second line of WM_CREATE.

Substitute DT_LEFT for DT_CENTER.

..... the text in the text box is centered..... The text box is drawn in the second line of WM_CREATE....

Hi Astro,

If I understood you correctly, just eliminate the BS_DEFPUSHBUTTON style in the second line and the text in the editbox will be left aligned.

Should be like :

Code Select Expand


invoke CreateWindowEx,NULL,ADDR TextBoxClassName,ADDR ButtonText,WS_CHILD or WS_VISIBLE,55,100,140,25,hWnd,1,hInstance,NUL


I usually handle all the control stuff (Static, Edittext, Groupbox etc.) in rsrc.rc file, partly because you can do some input filtering, formatting, text aligning and much more.

Btw, this is my first post, and no, I'm not am bot! Been lurking for a long time, learnt a lot. This forum is a great place with great knowledge! :U

Cheers.
