i am using an oledbcommand object to perform both insert and update based on the command text supplied and i am adding the parameters for update also in the order of insert. So incase of update though, its not giving any error/exception but database is not getting updated. Can any body pls tell me how to resolve this or any other way to implement both the functionalities using single method. Thanks in advance.

So is there any way to "Provide the Description of the function" along with the Prototype of the function which comes as default due to intellisence of MicroSoft. I tried the [Description("xgdfgdfg")] attribute above the function defination but no use. Can any body know how to get the user defined description for a function Thanks in Advance.

hi Gajatko, i don't know why any alternative is not working in my m/c. when i tried MessageBox.Show(Enum.GetName(typeof(enumCatalogExportStandard ), ImportStandard)); gave me a null string as output. i am sending the code snippets where ever i am using the enum related stuff in my code pls view. public enum enumCatalogImportStandard { CatccImportAsISO, CatccImportAsFGDC, CatccImportAsNative }; enumCatalogImportStandard ImportStandard; private void cmbTargetstd_SelectedIndexChanged(object sender, EventArgs e) { if (cmbTargetstd.SelectedItem.ToString() == "ISO") ImportStandard = enumCatalogImportStandard.CatccImportAsISO ; else if (cmbTargetstd.SelectedItem.ToString() == "FGDC") ImportStandard = enumCatalogImportStandard.CatccImportAsFGDC ; else if (cmbTargetstd.SelectedItem.ToString() == "Native") ImportStandard = enumCatalogImportStandard.CatccImportAsNative; } private void btnApply_Click(object sender, EventArgs e) { CImportCatalogRecordService.ImportCatalogRecordService objImpRecService = new CImportCatalogRecordService.ImportCatalogRecordService(); //below statement returning number instead of string objImpRecService.ImportStandard = ImportStandard; objImpRecService.InputFileName = txtImportFolder.Text + "\\" + Rec; objImpRecService.CatalogConnection = con; objImpRecService.Execute(out MetadataID); } this is all my code Pls view.
