Layer a Dialog with a bitmap

[Silvio.Falconi]

I wish show a bitmap on a dialog and make all transparent but it is transparent but i see also the border of the dialog
I tried also with oMessage:WinStyle(WS_BORDER, .f.) but the border of Dialos there is allways



How I can resolve ?

Silvio,

Please review FWH\samples\newhelp.prg

Press on the help button and then press on top of a control or the dialog itself.

[Silvio.Falconi]

yes I try it antonio same error

This sample works with current versions of FWH. I will separately post another sample that works with 17.11

Thanks to Mr. Silvio for sharing his bitmaps. I made a small change to the image.

Clicking callout button at the top, displays the callouts and clicking next time removes the callouts.
There is a provision to reduce the size of the callouts.

Good Mr Rao
I mean something of it also with a timer to show the message dialog for n seconds

ON INIT ( oDlg:Move( aPt[ 1 ], aPt[ 2 ] ),BuildTimer( oDlg ) )

Code: Select all  Expand view

function BuildTimer( oDlg )

   local oTimer
   local nStart := Seconds()

   DEFINE TIMER oTimer OF oDlg ;
      INTERVAL 10;
      ACTION If( Seconds() - nStart > 5, oDlg:End(),)

   ACTIVATE TIMER oTimer

return nil

Rao,
I have problem if I use many btnbmp

this command aPt := ClientToScreen( oBtn:oWnd:hWnd, { nRow, nCol } )

not give the right points where move the dialog of messages

[nageswaragunupudi]

I edited the sample.
Added 6 lines after ClientToScreen
Please implement this and try

[Silvio.Falconi]

please can see at email ?
I tried with your 6 lines but here not run ok
please try with 60 btnbmp for a sample

i tried with 20 and the btn is the 13

[Silvio.Falconi]

Mr Rao,
here not run ok
I made some test and the callout is draw far from the umbrela I wish
Please compile this sample
I cannot Use 128 sizes for umbrellas but 40/60
I add akso a timer timer
