Displaying sketches and tool output requires the full DLL. See the vendll example in VBASIC40 or VBASIC60.
Sketches
To display a Sketch use the vensim_show_sketch command as in:
Dim winint As Long
winint = Form1.Picture1.hWnd
result = vensim_show_sketch(1, 0, 100, winint)
The recasting of the hWnd as a Long (an Integer in 16 bit) is necessary because of apparent restrictions on argument types in Visual Basic.
If you want the prompts describing variable names to show on a sketch you will need to send Vensim the command SETTING>HOVERCOMMENT|1. By default the DLL does not display any of this comment information.
Tools
Dim winint As Long
winint = Form1.Picture1.hWnd
result = vensim_tool_command("WORKBENCH>Causes Tree", winint, 0)
The hWnd recasting is the same as for sketches. To display a WIP tool use:
winint = Form1.Picture1.hWnd
result = vensim_tool_command("CUSTOM>WIP", winint, 1)
Printing and Exporting
Dim winint As Long
winint = Form1.Picture1.hWnd
result = vensim_tool_command("PRINT>", winint, 0)
' or result = vensim_tool_command("EXPORT>", winint, 0)
To the only trick for printing is to get the right window.
