Draw Text

[hfheatherfox07]

Hi,
I was wondering is the re a way to center Multilines with DrawText Vertically?
It seems that DT_VCENTER only works with single lines :(

Code Select Expand


szText          db 'Text Line1',13,10
     db 'Text Line2',13,10
             db 'Text Line2', 0
This wont work

Code Select Expand

invoke  DrawText,        ps.hdc, addr szText,-1, addr rcClient,
                                 DT_VCENTER or DT_CENTER or DT_NOPREFIX

No. You need two invokes, the first with DT_CALCRECT.

@ jj2007
I don't understand what you mean ?

Have different data values ?
Like

Code Select Expand


szText          db 'Text Line1',13,10
szText 1     db 'Text Line2',13,10
szText 2       db 'Text Line2', 0

I have tried this ...does not seem right?

Code Select Expand

invoke  DrawText,        ps.hdc, addr szHello,-1, addr rcClient,
                                DT_CALCRECT or  DT_VCENTER
                               
invoke  DrawText,        ps.hdc, addr szHello,-1, addr rcClient,
                            DT_CENTER

"If the function succeeds, the return value is the height of the text."

- invoke DrawText, ... DT_CALCRECT
- mov edx, heightofbox
- sub edx, eax
- sar edx, 1
- add rc.top, edx
- invoke DrawText, ... DT_whatever

@jj2007 
Nice!!!  :t

That worked Great ..... The " heightofbox" is actually pixels from the top to go down

I will add a little Demo in case some one else runs into this

Thank You Again jj2007 !  :t

Here is that example in case some one else runs into this
