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 ...

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.

Okay I figured that one out. Works just fine. Dim strVensimVarName As String * 128 Do While (bExitLoop = False) strVensimVarName = "" nResult = vensim_get_substring(Buf(1), nFromPosition, strVensimVarName, 100) If (nResult <> 0) Then nFromPosition = nFromPosition + nResult ComboBox1.AddIte...

I am having similar issues with vensim_get_substring function call. So, I changed the definition similar to vensim_get_varnames to Public Declare Function vensim_get_substring Lib "vendll32.dll" (ByVal fullstring$, ByVal frompos As Long, Buf As Byte, ByVal maxbuflen As Long) As Long Do Whi...

Hi Bob, Sorry got side tracked on another project work. Anyways, I tried that and it doesn't seem to work either. It is expecting an array due to this declaration Private Declare Function vensim_get_varnames Lib "vendll32.dll" (ByVal filter$, ByVal vartype As Long, Buf() As Byte, ByVal max...

Bob, Still running into the same issue with changed code. Private Declare Function vensim_get_varnames Lib "vendll32.dll" (ByVal filter$, ByVal vartype As Long, Buf() As Byte, ByVal maxbuflen As Long) As Long Dim Buf() As Byte sFilter = "*" nMaxStringLen = vensim_get_varnames(sFi...

Thanks Bob. I'll try it out.

Hi everybody. I have a Excel workbook that loads and runs the Vensim model perfectly fine. When I am trying to call the variables the vensim doesn't seem to like something and it crashes Excel without throwing any error. Here's piece of code that I'm running in Excel.
