Try This.

Hello, 

  I tried it, it does not work. However when I tried to run the code I got the following message stating that a depnedency was loaded from a different path. the file is user32.dll

What is the error?

OK, run a search on your PC for the location of user32.dll. It normally resides (on XP at least) in the Windows\system32 folder. Generally with windows dlls like this, you don't need to explicitly provide the path.

As a workaround you could try giving the call library function node the full path of the dll, eg. C:\windows\system32\user32.dll. Paste the full path in to the 'library name or path' box (bring up by double clicking the two Call library function node icons) and then try again.

(This method of pointing to the DLL might fall over if you move the code between machines that are set up differently so is best treated as a temporary fix)

Let us know how it goes.

Hello,

   In order to try this code out I had to install Labview 2010. Currently running Labview 8.2. The top cell of the library is "drop_down_demi.vi". When I run the code I am assuming that all I have to do is to click on the front panel control "Trigger Drop Down" and the complete contents of the drop down menu from the Ring would appear. Well nithing happens when I click on the "Trigger Drop Down" button. Here is a text file of the warning that I get from the code.

Did you try the version I attached?

Here it is in v 8.2

Hello,

  Thanks! this code works! I will have to look at the block diagram and get a better understand of how the position of the window affect the operation. Thanks again!

Glad you got it working. Post questions if you have them.

Cheers
