Hi
I make this lua script for "OpenDialog":

Code:
function ButtonOpenClick(sender)
    local child1 = control_getParent( sender ); -- button to panel
    local child2 = control_getParent( child1 ); -- panel to form

    if( frmCheat_ldCheat == nil ) then
        print( "its nil" );
    end

     openDialog_execute( frmCheat_ldCheat );
end


Q1:Now how to make script for open pictures types only(Pictures Types(jpg,png,...))?
Q2:How to make with "OpenDialog" script that when open the picture the dimensions of the form to the size of the picture dimensions?

Thanks for your answer

a1:
if you're using the form designer, then go to the ldCheat object (using the treeview in the object inspector) , go to the filter properties and click on the ... button
in there you can give it a name and in filter the extension you wish (multiple)

e.g:
Code:

All image files  |      *.png;*.jpg
Jpg files        |      *.jpg
Png files        |      *.png
Dot files        |      *....


but you can also set the property at runtime
e.g:
Code:

frmCheat.ldCheat.Filter="All image files|*.png;*.jpg|Jpg files|*.jpg|Png files|*.png|Dot files|*...."


a2:
Code:

if frmCheat.ldCheat.execute() then
  local p=createPicture()
  p.loadFromFile(frmCheat.ldCheat.FileName)
  frmCheat.ClientWidth=p.Bitmap.Width
  frmCheat.ClientHeight=p.Bitmap.Height

  --and do other things with p like assigning p to a image.Picture or something
end

DB has already given you the answer to that question.

If you can't figure it out from that, then read main.lua and try to learn from it. Considering you've already been told that multiple times in the past (and you're still using those old undoccumented functions), it's clear you haven't and probably never will do that.
