How to get the List of dataset loaded for simulation

Hi All,
I am using MENU>LOAD_RUN|? in a vb.net program to open the dialog box to load the datasets.
Below is the sample Vb.net code I used
Code: Select all
Dim result As Object
result = vensim_command("MENU>LOAD_RUN|?")
I want to know how to get the (names or counts)of the list of loaded datasets for the simulation.
Thanks

Thanks very much.
I am having a difficulty on how to call the vensim_get_info function especially on how to supply the variable(s) to the function.
Below is my sample code
Code: Select all
Dim testresult As Object
Dim testbuf As String = ""
testresult = vensim_get_info(10, testbuf, 500)

Try the following. The string you are passing to Vensim was zero length ("") but you are telling Vensim that it is 500 chars long.
Code: Select all
Public Declare Function vensim_get_info Lib "vendll32.dll" (ByVal infowanted As Short, ByVal buf$, ByVal maxbuflen As Short) As Short
Code: Select all
Dim nMaxStringLen As Long
nMaxStringLen = 500
Dim sBuffer As String
sBuffer = New String(" ", nMaxStringLen)
nResult = vensim_get_info(10, sBuffer, nMaxStringLen)
