Try:

DataSET.AcceptChanges();

Also, "Bob" is a much nicer name for a database table; surnames are reserved for school and the military Smile | :)

hehe, true and thnx for the reply, unfortunatly it doesnt make the table update Frown | :(

i ammended the code to (i have placed it after the mapping too, jsut in case..):
lol, also changed the table name to test!

DataSET.AcceptChanges();<br />
DataAdapter.TableMappings.Add("TableData", "Test");<br />
DataAdapter.Update(DataSET, "TableData");<br />
DataAdapter.TableMappings.RemoveAt("TableData");

But it still doesnt update the mysql table Frown | :(

im am very confused, i think maybe my DataAdapter.Update() line may be wrong

many thanx again, i think i need your added line aswell as the code fix!

Can anyone help, im going insane with this one :P

I don't believe you can expose the C# form to the v6 application, but you can expose that enum to a vb6 by creating a dll and adding a reference to it.

There is a new toolkit from Microsoft for exposing .NET UI stuff to VB6 apps, but I can't remember what it is called.

Problem with office XP interop assemblies

I'm trying to write an application that will allow an external device to be synchronized with a PowerPoint presentation. So I wrote a very simple Windows Forms application that will load a PowerPoint presentation and get a list of the slides. It then allows the user to hook each slide to an event on the external device with the objective being that when that slide appears, the external device should do a certain action. I'm using the office XP primary interop assemblies from Microsoft and all of this works fine up to this point.

Now I have a button that starts the actual presentation. My program will handle the SlideShowNextSlide, SlideShowEnd and PresentationClose events (from PowerPoint) and everything works great. My handler is triggered when the slide changes and based on which slide is displayed, it makes the external device do something.

The problem occurs after the presentation ends and I then try and restart it. At this point when I get to the SlideShowSettings.Run() method I get a COMException with the message "Presentation (unknown member) : Object does not exist."

Does anybody have any idea what the problem here might be? I'm assuming that something needs to be cleaned up on exit, but I've closed the presentation with the Close() method and even tried reinitializing a whole new PowerPoint.Application and PowerPoint.Presentation, but it just doesn't work.

Hi,

I never do these things, but IIRC I read something like that on CodeProject
a couple of months ago.
I think this has been a bug, and some patch exists to solve it.

So I suggest you search CP for it (using the looking glass), or else just Google it.

Smile | :)

When you created your dynamic controls, did you add the controls to the Page.Controls collection?

Might be the controls are not getting added to the page
Where are you adding the controls to the page ?
First check by debugging the application

Thanks and Regards

Are you counting the controls on postback? On a postback, you have to create and add all the controls again.

Ramu,

Have you tried Googling for that? If you did, you might have come with http://www.codeproject.com/csharp/DesktopCaptureWithMouse.asp, which would show you how to do it...

Thanks you very much.

Here is an example(getting the value of a cell of the first row selected ):

<br />
DatagridView oGrid;<br />
<br />
//If you know the ordinal of the column<br />
if( oGrid.SelectedRows.Count>0 )<br />
{<br />
    object oValue = oGrid.SelectedRows[0].Cells[0].Value;<br />
}<br />
<br />
<br />
//If you know the name of the column<br />
if( oGrid.SelectedRows.Count>0 )<br />
{<br />
    object oValue = oGrid.SelectedRows[0].Cells["colName"].Value;<br />
}<br />
<br />
//Then you can try to Convert the object to a different type.
