Just to close it off for prosperity.
I have a data table, filled by a table adapter with '...WHERE(PK=@PK)'. It had a single row in it. I added another row (.NewRow, .AddRow). The Rows count of the table was 2. Index [0] pointed to the old origional data. Index [1] pointed to the new data, DataRowState=Added.
I then called the table adapter.update (a rather large INSERT statement)
There was still a count of two rows but both [0] and [1] pointed to the same row, the origional. This would indicate the data table of the dataset is no longer valid after an Update. I then did another fill and the data table had both rows as before (now unchanged state).
The reason for writing this is to record for other people that may fall into this minor but time consuming trap. The tableAdapter.Update call is the end of the road for the validity of the data table data. There isn't a lot of documentation or web resource that tells you this.
It maybe obvious to seasoned .NET database engineers, and maybe standard practice. It would be unexpected to new entrants in this field with experience of other, dare I say it, more normal, caching systems.
Thanks for the help.
Ooops, I modified Table Adapter to refer more correctly to the data table of the dataset where referring to storage.

Man you should be a comedian... you seem to have a beeter angle on that then programming!
However ... TO answer your first question just put a shortcut to your application in the startup folder on windows....
Not sure on the other answer....

Do you honestly think that a forum reply will teach you how to write a spell checker ? Buy one, use Word, or give up.

Creating your own would be more difficult than using an existing one. There are some free solutions available, so why would you even want to create your own wordlist?

If you're not smart enough to find the ASP.NET forum, this task is probably too hard for you

Hello All
Kindly help me resolve the issue. I want to fill multiple values in a single cell of excel using c#. The values are received from a loop.
Thanks

If they go in the one cell, I assume you want to build them into one string and hten insert that ? If not, please ask in a way that makes sense

This is ridiculous. No beginner should be working on such a thing. LEarn C# first. If this is paid work, be ashamed.

Hi,
Please let me know how can i use UrlDownloadToFile() in c# .....
|

IS it a .NET method ? If not, then perhaps you need to use p/invoke. Either way, you don't say what you want to use it for, or why you can't google it for yourself.

this is the customer class(created by XSD) which i use to create the customer object at client
and pass to web service.
public partial class Customer {
private System.DateTime dATEOFBIRTHField;
private string cUSTEMAILField;
[System.Xml.Serialization.XmlAttributeAttribute()]
public System.DateTime DATEOFBIRTH {
get {
return this.dATEOFBIRTHField;
}
set {
this.dATEOFBIRTHField = value;
}
}
[System.Xml.Serialization.XmlAttributeAttribute()]
public string CUSTEMAIL {
get {
return this.cUSTEMAILField;
}
set {
this.cUSTEMAILField = value;
}
}
}
when i set the date of the customer object
customer.DATEOFBIRTH = DateTime.Today;
and pass it to web service by calling it's method at client side the time is
automatically set to "01/01/0001" . any suggestions why?

Hi,
the DateTime.Today property returns a value like
"03/16/09 12:00:00 AM" whereas your method's argument might need only the date or time.....
Check this and if you need to pass anyone modify your code accordingly....
Have a Happy Coding.....

I got this error, And here is my code . Thanks
case 64:
if (GetFunction() == true)
{
if (GetStatus() == false)
{
FunctionError();
}
else
{
Reset();
goto case 65;
}
}
|

The goto is inside the brackets. You need a break after the if, or after FunctionError()
using goto in a case statement is so ugly. THe C# team are morons for requiring us to do this. I never do it, no matter what.

Do you have any recommendations for this case ?
|
|
|
|
|
How about moving the code inside case 65 into a function and calling that from both places?
|
|
|
|
|
Yes, that's what I would do.
