Well, if a simple count as Mycroft suggests isn't good enough you are going to have a problem - different processors, memory etc etc. You could time the 1st iteration and use that combined with the number of records to give a rough approximation I expect.

Hello every one..
I will re-describe my objective...
I have a application working over a network and having a centralized DB server..
For new registration we were generating a ID by combining YYYYMM(a number sequence). The sequence is stored in a table.
Now we have to modify the application so that the registration can be done at more then one place.
I read the Number and add 1 to it, insert the registration info in register table and then update the number.
Now my issue is when we will start doing registration at two places there are chances that both the system will access the same number and there can be c conflict...
I just knew that this type of things are possible by table locking some kept table locking in the subject..
Can any one plz help me out with what exactly i need to do and may be how also..
Regards

And you will still get the same answer: Transaction. Transaction is basically a "managed" row locking so why "unmanagedly" locking the whole table and potentially causing nobody to be able to use the table?
Also throw aways the table locking idea that exist in the file-database era (Access etc).

I have to say, there's no better way, it's what they were made for - controlling update sequences amongst other things.

Listen to darklev - use a transaction in your stored procs to insert to the various table.

Any pointer is appreciated.

Does anyone know how I can loop through a collection and start a thread to process  each item in the collection, but I want to limit the number of threads running at a time to the number of cores on a PC.

I've always found this to be pointless. How many threads are already running system-wide before your app even starts?? 10? 50? Try over 200. So, whats another thread going to matter? Why limit your threads to 2 or 4?

I share your view Dave, unfortunately I cannot override my management. With that said have you come across this problem? How did you solve it?

Only in a thought experiment. But, you can get the processor count from
Environment.ProcessorCount . You can then create your own threads and set their ThreadAffinity to get them to try and run on a particular processor if you want.

I found where to get the processor count. The trouble I'm having is creating a loop to process items in a collection from a thread and limiting the number of started threads to the number of cpu's. Lets say I have a thousand items in a collection and a dual core processor. I only want to start 2 threads at a time to process the thousand items until completed .

I have a 32bit application built on vb.net2003 that uses the bundled crystal reports.
It installs and runs flawlessly on XP platforms.
when I install it on Vista Business (x64), the app runs fine, but any attempt to generate a report (that is, to instantiate a derived report class, as in, "dim rpt as new rptWhataver") results in
Cannot find KeycodeV2.dll, or invalid keycode.
keycodev2.dll is in fact present, and the app was built properly with the keycode property.
again, this app, and the reports work fine in about 1000 locations around the world on XP, win2k, and (gasp!) win98se. Anybody have a suggestion or work-around?

Hello every one
Can some one plz help me with example of table locking. Wat i want to achieve is to lock the table for the time user one is doing read immediately followed by a update. If user 2 access the table he should be able to do so after the user1's operation is over
I am using datareader to read data.

Table locking is not what you are looking for. What you should use is a transaction.
Despite everything, the person most likely to be fooling you next is yourself.
|
|

Table locking is only for very specialized circumstances. Locking antire tables severely limits your app's scalability and increased administraive overhead. Think about it. If you app locks a table, then crashes, what do you do?? The lock doesn't clear itself...

Good Afternoon All
Am Overriding the Paint Method. i need to Change Colour based on the Value of a Certain Column. The Following Code Will Look for that Value in Every Column and Change the Colour in those Cells.
Dim o As Object<br />
o = Me.GetColumnValueAtRow(source, rowNum)<br />
If (Not (o) Is Nothing) Then<br />
Dim c As Char<br />
c = CType(o, String) '.Substring(0, 1)<br />
If (c = "True") Then<br />
' could be as simple as<br />
' backBrush = new SolidBrush(Color.Pink);<br />
' or something fnacier...<br />
backBrush = New LinearGradientBrush(bounds, Color.FromArgb(255, 200, 200), Color.FromArgb(128, 20, 20), LinearGradientMode.BackwardDiagonal)<br />
foreBrush = New SolidBrush(Color.White)<br />
End If<br />
End If
How can i change the Change the Entire row based on a Value in a Certain Column
Thanks
