for a test I created a map with a few pushpins, I named the dataset "toto" and I saved the map as "toto.ptm"

I put the ActiveX control (MappointControl1) on a VB From

I put this in a command button.

Code:

Dim objdataset As MapPointCtl.DataSet
Set objdataset = MappointControl1.OpenMap("C:\toto.ptm").DataSets("toto")

It works. Can you try again with a new map (make a test map), try just adding the few lines of code to keep it simple.

Thank you very much. (sorry for my bad english).

Your code lines work.

Nevertheless i have a new question : why my prog doesn't work???? Why must i use the active X with a declaration like dim "variable" as MapPointCtl.something and not dim "variable" as Mappoint.something???,
What is exactly the difference between these 2 declarations???

Still thank you for your assistance.

What is the difference between the Application object and the MappointControl object? I think i don't understand this.
thanks a lot.

From MSDN

Using the Control is similar to using the standard MapPoint automation. The Control has methods and properties that are analogous to the Application object and provide access to the objects in the MapPoint object model. For example, you can call the ActiveMap property of the MappointControl object to get the current map, just as you would call the ActiveMap property of the Application object in the MapPoint object model. The Map object that is returned and all child objects that you can access are the same type as the ones in the MapPoint object model. For the most part, code that you write, for example, in a MapPoint COM add-in will work in the Control as well
