I have a program that uses disconnected recordsets on the client side : 
 
Here is the problem I have : 
 
Client gets a dataset , say a customer table 
 
Creates a new customer 
 
Deletes this customer 
 
Updates changes to server. 
 
The server code detects that a record has been deleted via rowstate, takes 
 
the new ID of the deleted record ( generated by the client side table via 
 
setting autoincrement to true and setting the seed to the last ID + 1). 
 
Now this causes 2 problems :

I am using the following code in 2 separate sub routines: 
 
Dim xlApp As New myExcel.Application 
 
Dim xlBook As New myExcel.Workbook 
 
Dim xlSheet As New myExcel.Worksheet 
 
xlBook = xlApp.Workbooks.Add 
 
xlSheet = xlBook.Worksheets.Add 
 
In one subroutine it works fine, in the second subroutine, i get a 
 
"Additional information: COM object with CLSID 
 
{00020819-0000-0000-C000-000000000046} is either not valid or not 
 
registered." error. 
 
Any ideas?

Hey all, 
 
Ok, here's another of my fun questions.  I want to rewrite the textbox 
 
control in VB.NET.  I need to implement superscript and subscript 
 
within the box.  Don't ask why, but I can't use RTF as my superscript 
 
and subscript's are always numbers and are defined as specific 
 
characters.  ie. char(192) = superscript 1 
 
Does anyone know how to inherit and change the onPaint method of the 
 
textbox?  I have created my own controlt o try and do this but 
 
apparently the onPaint ...

on this ASAP to respond to a client.  Can anyone advise on how to approach 
 
this? 
 
Thanks.

Hi, 
 
We have an existing vb.net application.  It works fine, but the design 
 
isn't good.  We hired a designer who built a great design and sent us all 
 
the button graphics, etc. 
 
It is more difficult than I thought to apply the new design because the 
 
app is currently built as 1 form with over a dozen panels that are 
 
switched back and forth.  Panels are in the way like crazy!! 
 
Should I convert all the panels to independent forms?  Or leave them be? 
 
Is there anyway to hide them ...

I'm having a problem with VB 2005.  I'm trying to compare 2 dates as 
 
follows: 
 
If AddTo <= AddFrom Then 
 
'Error Code 
 
Else 
 
'Happy Code 
 
End If 
 
AddFrom should be earlier than AddTo. 
 
This works great unless the AddTo has a time in the 12:00 AM hour and 
 
AddFrom has the same day as AddTo but a later time. 
 
Example: 
 
6/26/2006 12:00:01 AM      6/26/2006 11:45:00 PM - True 
 
6/26/2006 12:00:01 AM      6/27/2006 11:45:00 PM - False 
 
6/26/2006 1:00:00 AM        6/26/2006 ...

Hi, 
 
I have a project, that doesn't appear to process frmMain at all - I break at 
 
form_load, and nothing happens. The form shows, but has done no processing 
 
in the form load. 
 
I have tried having frmMain as my startup object, and also 
 
Dim frmy As New frmMain 
 
frmy.ShowDialog() 
 
But my frmMain appears, without going thru the form_load. 
 
This is driving me mad. If I change to startup with a different form, all is 
 
OK. 
 
Anyone any ideas please 
 
Thanks

I got a datagridview on which I do an update, the sace works fine, but after 
 
the save, the newly saved values do not get displayed in the cells. It looks 
 
like I need to do a refresh of some sort to get that info to display, but I 
 
want it to display and return to the selected rows both in the parent 
 
datagrid and in the two child datagrids, related to the parent. 
 
I would appreciate it if anybody could tell me whats the best way of getting 
 
this, a code snippet sample would help.

I have a CreatedOn field , datetime, which has GetDate() as the default 
 
value in SQL server 2000 table. When I create a new record in the table 
 
itself in enterprise manager, the field gets populated OK, but when I try to 
 
create a new record with a Microsoft datagridview control, I notice that the 
 
datecreated value does not get created. It looks as if the datagridview 
 
insert statements overrides the default value and prevent the default 
 
defined in the table to get written.

Thank you in advance for any and all assistance. I have a control 
 
"tv_ClientMain" that populates with nodes of system information, software,
