Error Code -2147221296 (0x800400D0)

Can anyone point me in the right direction for an explination of this code? I can't find any hits on it.

I have a VB6 sample app that reads a T-SQL script from a file and feeds it to SQLServer.ExecuteImmediate. All very pedestiran. When the script works it works great. When it doesn't, say a bad table name in a select, the function ends with Error Code of -2147221296 (0x800400D0) and a Description that indicates the error in some cases. In another case (a DCOM exe), the description is always "Method '~' of '~' failed". Does the caller being an out-of-processs class matter?

Is this a DMO code, a ODBC or OLE/DB code, a COM or OLE code, or what? I've been looking for this answer for a long time now. Any help would be much appreciated!

Additional info:

If I use Database.ExecuteImmediate instead of SQLServer.ExecuteImmediate then I get a real DMO error code...

Error automating SQL DTS Pkg from VB6 to VB.Net

I am trying to convert a VB6 SQL 2000 created code into VB.NET. Everything
complies fine but then I get this error message:
An unhandled exception of type 'System.InvalidCastException' occurred in
Project1.exe
Additional information: QueryInterface for interface DTS.CustomTask failed.
This is the portion of the code that it is breaking on:
I found 2 ways to do this but both ways are giving me the same error message
Way #1:
Public Sub Task_Sub1(ByVal goPackage As DTS.Package2)
Dim oTask As DTS.Task
Dim oLookup As DTS.Lookup
Dim oCustomTask1 As DTS.DataPumpTask2
oTask = CType(goPackage, DTS.Package2).Tasks.New("DTSDataPumpTask")
oTask = goPackage.Tasks.New("DTSDataPumpTask")
oCustomTask1 = oTask.CustomTask
Way #2:
Public Sub Task_Sub1(ByVal goPackage As Object)
Dim oTask As DTS.Task
Dim oLookup As DTS.Lookup
Dim oCustomTask1 As DTS.DataPumpTask2
oTask = CType(goPackage, DTS.Package2).Tasks.New("DTSDataPumpTask")
oCustomTask1 = oTask.CustomTask
If anyone has an idea on what I need to change in the code I would greatly
appreciate it.
Thanks in advanceJohn,
