View 2 RepliesI have just received an interesting feedback from a VB.NET customer using our product - for some reason intellisense hidden a certain enumeration value.After a small testing I have found that this is likely a bug in IntelliSense: [URL]..To be honest, I did not expect this problem with such a basic stuff like this. Have you seen this in the past? For me, it doesn't work in all VS versions...
Anyway, feel free to track this issue if you are coding in VB.NET.
I have a .NET library that needed a COM wrapper around it so it could be called from VB6ish programs, in this case specifically Microsoft Access XP I have a type that's declared in one of the classes that went into the .NET library. I thought since its public, it would be seen, but it didn't show up in Access. And yes, we made the TLB file and registered the COM interface. I had to move the type declaration into the COM module, which I really didnt want to do. Is there a way to export a type/enum through COM without actually declaring it in the COM interface Scott Berger McCormick Systems

View 1 RepliesI didn't like how the SqlCommandBuilder generated it's Update command, so I'm making my own with the following code.. This is a large table and I didn't want to get a concurrency error just because I changed field A a few seconds after someone else changed field F.It works great but as you can see I manually have to exclude the Memo field because this is a TEXT datatype field and so you can't use WHERE for that.
Is there any way to get the sqlDbType for each field so I can use this procedure to easily generate all Update commands I need? I have tried GetType but that returns String for this field..
Dim strUpdates As String = "", strClause As String = "", strColumn As String
Dim dr As DataRow = dsDemo.Tables("demo").Rows(bsDemo.Position)
Dim sqlCmd As New SqlClient.SqlCommand("", frmMain.cn)
For i As Int16 = 0 To dr.ItemArray.Length - 1
strColumn = strColumn.ToString.ToLower
