Hello,
I am brand new to vds, still using the shareware. So please be patient with my ignorance. There are no books on vds to help guide me, only the woefully inadequate help documentation and this users forum:)
I am trying to write a little picture viewer script with vds. This involves a listbox on the left of the dialog, wherein you click an entry in the list and a corresponding picture (bmp) pops up on the right. Complicated, eh? Well it is for me! lol
Perhaps some code already exists for this common app somewhere, and you can provide me with a link. If not, a quick explanation of how to do the above would be greatly appreciated!!
Thanks,
Ben |

Start VDS and bring up the dialog designer by hitting F2. Add a list and a bitmap element, for this just leave it as list1 and bitmap1...make the list have "click" as a style. Also add a button (button1) and make the caption "Change Directory". Place the button below the list.
| Code: |
rem get the bitmaps
list filelist,list1,*.bmp
rem wait for an event to happen then jump to it.
:evloop
wait event
goto @event()
rem happens when the "x" is clicked
:close
exit
rem button1 is pushed
:button1button
rem access directory dialog from windows api
%%dirdlg = @dirdlg()
rem if cancel was not pushed and a directory was selected
if %%dirdlg
directory change,%%dirdlg
list filelist,list1,*.bmp
end
goto evloop
:list1click
rem set bitmap
dialog set,bitmap1,@item(list1)
goto evloop
|
For an advanced excercise, change this to where list1 is floating in a seperate window than bitmap1. Use dialog select,0 and dialog select,1 to access the proper dialog elements in each window. Also try making bitmap1 stretch style and making the dialog resizable. Use @dlgpos(,WH) to get the width and height of the window and dialog setpos,bitmap1 to set the bitmap to fill the whole window.

In my case, new to vds, I need an overbearing parent . Like tsunamai, thanks for the quick response, as well as the code with comments. I'll get on it tonight, you guys are great.
