I have just spent a very frustrating morning reading postings on this problem
and nothing seems to work. I am trying to write a demo project in VB/ASP.net
2.0 and I am unable to get any sort of edit page to work. This is extremely
simple stuff, straight out of one of Microsoft's training videos. Drag a
table on to the xsd, create queries, then create a page with a bound
DetailsView (bound to a tableadapter). Then set the DetailsView to permit
edits. (The initial display of data works fine.) No code whatsoever.
No matter what I try, when I try to update the data I wind up with the
error:ObjectDat aSource 'ObjectDataSour ce1' could not find a non-generic
method 'Update' that has parameters: ItemName, ItemDesc, ProjectLeadID,
StartDate, FinishDate, GatesId, Resources, original_Projec tId,
original_ItemID .
Is there any way to get this to work?

ObjectDataSourc e expects its underlying type to have a method named Update.
Does yours have one? That's what the exception is saying. if you need sample
code, visit the ASP.NET Quickstarts tutorial at the asp.net website.

Ignore previous 'expression of opinion'. Finally found enough to get it to
work, at least in this example.
Basically:
1. Go into the update command string, eliminate all references to key fields
in the SET section, and get rid of anything that ISN"T a key field in the
WHERE clause.
2. Then setup the gridview in the usual fashion, but then go into the html
and set OldValuesParame terFormatString ="{0}"
When are they going to fix this?

Thanks. The PDFs may be of some use, but what are those people at ASP.net
thinking? They've forgotten to put the solution files in with the sample
code.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
