Slider Control

[Jonathan Bristow]

Does anyone know how i can set the Slider Position at the Form_create stage?
Reading back the nPosition is easy in the hscroll callback.

Hi Jonathan,

The initial slider position can be set using the "Value" property at design time (you probably already know that).

You can set the values in the WM_CREATE message handler as follows (This sets a slider with min 1, max 10 and a position of 5.

Code Select Expand


   SendMessage hWndControl, %TBM_SETRANGE, %TRUE, MakDwd(1,10)
   SendMessage hWndControl, %TBM_SETPAGESIZE, 0, 1
   SendMessage hWndControl, %TBM_SETLINESIZE, 0, 1
   SendMessage hWndControl, %TBM_SETTICFREQ, 1, 1
   SendMessage hWndControl, %TBM_SETPOS, %TRUE, 5


The above may look familiar because I cut and pasted it directly from the code that FireFly generates for the Form.

Fantastic, works fine now. Thanks
