Hi both,
Kaul:
You can't use an ActiveX DLL from MapBasic, so that idea won't work. Only
plain DLLs are usable, which puts VB out of the question. You'll need C++
or Delphi to build your DLL.
David:
Yes, you can call individual MapBasic subroutines in Integrated Mapping,
but not as easily as you describe it. First of all, your example asks
MapInfo itself to call a subroutine inside an unnamed MapBasic program,
which off course doesn't work. And then you can only call the
RemoteMsgHandler subroutine, by use of the Do method on the MBX (!) object:
Set miObj = ...
Set mbxObj = miObj.MBApplications("FooHolder.mbx")
mbxObj.Do "text parameter to RemoteMsgHandler sub"
In the RemoteMsgHandler sub you retrieve the submitted text parameter with
CommandInfo(CMD_INFO_MSG), and possibly decode it yourself. From this sub
you then call your Foo() subroutine in the same MapBasic program, e.g.:
Sub RemoteMsgHandler
Dim param as String
param = CommandInfo(CMD_INFO_MSG)
Call Foo (param)
End Sub
Hope this helps.
Best regards / Med venlig hilsen

Hi David
why don't u make a ActiveX DLL of your wondorous code in VB
and then call that function in your MapBasic application....

Integrated Mapping: Calling a function in MBX

Please respond to "Cautley,

Is is possible to call a function inside a running MBX from Visual
Basic?
Consider the following simplified MBX:
==============================================================
Declare sub Main()
Declare Sub Foo(strSomething as string)
Sub Main
' make some menus, etc....
' stay loaded when you're done
'
End Sub
Sub Foo(strSomething as string)
'
' do wonderous things...
'
End Sub
==============================================================
Is there some way, inside Visual Basic, that I can call "Foo"?
.... Launch Mapinfo, stick handle in mMIInstance
' run the mbx...
mMIInstance.do "run application FooHolder.mbx"
'
' now, what can I do to call foo? The following doesn't work, as
any function call from the mapbasic window is doomed...
mMIInstance.do "call Foo(HelloWorld)"
Thanks.
