How to access subscripts control dialog in VenApp?

newbie · Post by **newbie** » Fri Jan 02, 2009 10:04 pm

Hi,

I am trying to build a VenApp where the user can update the range for one of the subscripts. How can I do this?

Thanks,

use the SPECIAL>SUBSCRIPT command.

There is indeed a problem with the SPECIAL>SUBSCRIPT command. This will be fixed in the next release which should be Jan 16 or so.

Hi Bob,

Just wanted to get an update from you regarding this fix as you had mentioned earlier. I have downloaded the last release 5.8d, but the issue still exists. Could you please check and let me know.

Thanks.

I just tried this and it seems to be working fine in 5.8d. The format for the command is

BUTTON,"Set Subscripts",34,43,8,3,,,SPECIAL>SUBSCRIPT|?,

to bring up a list of all subscripts of

BUTTON,"Set Subscripts",34,43,8,3,,,SPECIAL>SUBSCRIPT|Firm|?,

to select which firm (assuming Firm is a subscript range).

Hi Bob,

Thanks for the update. I tried this command and it works fine and brings up the Projects subscript window.

string strVensimCommand = "SPECIAL>SUBSCRIPT|PROJECTS|?,";

Now, if I want to set the value of the subscript PROJECTS then how can I do that?

In the model, Projects is defined with this equation: (project1-project5).

I want to be able to change this equation for Projects dynamically from code. so, if I want to set the equation to (project1-project10) I should be able to do that.

Thanks.

This is just

SPECIAL>SUBSCRIPT|PROJECTS|Project4

etc.
