[EnergyPlus_Support] Re: Running simulation using VB
I tried the first option but it keeps telling me that it can't find the Energy+.idd file although its in the same directory.
Here is the code,
Private Sub CommandButton1_Click()
Dim RetVal
RetVal = Shell("C:\EnergyPlusV3-0-0\RunEplus.bat plant LasVegas", 4)
End Sub
Upon execution, a command window appears instantaneously then disappears, and no results are stored.
Appreciate your help.
