Please help me solve my problem : COMException Error

[Anonymous]

Hi. everyone!

Please help me solve my problem.

I want to use SDFToolKit (SdfComTk.dll) in my Asp.net with C# sample
project with VS 2003.
I use SDFToolKit about Autodesk Mapguide Version 6.3.

To Read SDF file is no problem and no error
But...

1 sdfOpenRead ===> --> The problem does not exist.

2 sdfOpenUpdate ====> The problem happens in the remainder. :
COMException Error
4 sdfCreateNew ====>COMException Error
8 sdfCreateAlways ====>COMException Error
16 sdfOpenAlways ====>COMException Error
32 sdfOpenExisting ====>COMException Error

================ ex sample ======================

private void Del_Click(object sender, System.EventArgs e)
{
SdfToolkitClass poTlKit = new SdfToolkitClass();
SdfObject obj = new SdfObject();
SdfOpenFlags flags;
String TestVal = "Test1000";
String sdfFile = "c:\\sdf\\test.sdf"; //exist test.sdf , test.sif,
test.kif

// flags = SdfComponentToolkit.SdfOpenFlags.sdfOpenRead; // --> The
problem does not exist.

flags = SdfComponentToolkit.SdfOpenFlags.sdfOpenUpdate |
SdfComponentToolkit.SdfOpenFlags.sdfOpenExisting; //---> the error happens.

try
{
//poTlKit.Open (AwFile, flags, true);
poTlKit.ISdfToolkit_Open (sdfFile , flags, true); // ---> COMException
Error
poTlKit.BeginKeyIndexSearch(val);
obj = poTlKit.SearchToNextObject();
poTlKit.EndSearch();

poTlKit.BeginUpdate();
poTlKit.DeleteObject(obj);
poTlKit.EndUpdate();
poTlKit.Close();
}
catch(COMException err)
{
WriteBlue("COM Exception Error : " + err.Message);
}
catch(Exception err)
{
WriteBlue("Exception Error : " + err.Message);
}

}


Thanks.

what is the err Number of the exception?

Do you have a .KIF file?
