I am creating a series of gif files based upon location information that I feed to Map Point. I use the 'Save As' method to push the map into an HtML. I grab the image and push it into an Image Object. Then I repeat the routine. And something is holding on to the image. The Map Point Application has been cleaned up as well as the ancillary objects I use (Map, Location, PushPin), etc. Is there something I am missing?
It goes something like this:

objMapApp = new mappoint.application
objMap = Find(some criteria)
objMap.SaveAs(htmlpath,saveashtml)
objImage = Image.fromFile(imagepath & "image_map.gif")
objMapApp.quite
objMapApp = nothing

This works fine until I repeat the process... then nothing can touch that image file (no system.io operations, no MapPoint.SaveAs)

Any thoughts?

Have you ruled out this FromFile Method part of the code?

Code:

objImage = Image.fromFile(imagepath & "image_map.gif")

Right now, I'm getting around it by generating a random file name for each new html I create. And everything is being created correctly.
But I still can't clean up the files until I leave my application.

Somewhere, something in MapPoint isn't being cleaned up correctly, but I think my code cleans everything possible. But either I am wrong, or the mere reference to MapPoint creates some type of wrapper that runs along with my application, or I have no idea what is going on.

Smile.

Or you could use a picture object (untested code).

Code:

    Dim mpUtil As New MapPointUtilities.MapPointUtilities
    Dim pict As StdPicture
    Set pict = mpUtil.GetPictureFromObject(mpApp.ActiveMap)

If you want to do it in VB.NET you might run in to trouble (as I did), so here's what you do there:

Add a class to your project (remember to add a reference to stdole):

Code:

Public Class ConvertImage
    Inherits System.Windows.Forms.AxHost
    Public Sub New()
        MyBase.New("59EE46BA-677D-4d20-BF10-8D8067CB8B33")
    End Sub

    Public Shared Function ImageToIPicture(ByVal Image As System.Drawing.Image) As stdole.IPictureDisp
        ImageToIPicture = GetIPictureFromPicture(Image)
    End Function

    Public Shared Function IPictureToImage(ByVal Image As stdole.IPictureDisp) As System.Drawing.Image
        IPictureToImage = GetPictureFromIPicture(Image)
    End Function
End Class

And then call the code as this (having an imagebox on your form called Picture1):

Code:

        Picture1.Image = ConvertImage.IPictureToImage(mpUtil.GetPictureFromObject(mpApp.ActiveMap))

have you tried to sleep a few seconds between the two saves? I have found that this helps to sometimes solve weird MP behaviour.
