I set all my business layer classes as sealed class. I did like this because I read from somewhere that this will improve the performance. Is it true?
Thanks and Regards,

I set the class as sealed class when I want to prevent derivation.. That's all. I never heard that the sealed class is better than the normal class..

A sealed class cannot be used as a base class. For this reason, it cannot also be an abstract class. Sealed classes are primarily used to prevent derivation. Because they can never be used as a base class, some run-time optimizations can make calling sealed class members slightly faster.
I copied the above sentance from MSDN 2005
Thanks,

1. Return the SCOPE_IDENTITY() from stored procedure
2. Use ExecuteScalar to get this value.

Hello Everyone,
I did a little searching around and couldn't find a good answer to this problem. I have multiple files, of multiple file types, that I would like to push to the client side with one button click. I'm doing one at a time just fine in the following fashion:
PDFGenerator oPDFGenerator = new PDFGenerator();
byte[] oByte = oPDFGenerator.Genereate52670a1PDF(Page.Request.PhysicalApplicationPath);
if (oByte != null)
{
this.Page.Response.ContentType = "application/pdf";
this.Page.Response.AddHeader("Content-Disposition", "attachment; filename=52670a1.pdf");
this.Page.Response.BinaryWrite(oByte);
this.Page.Response.Flush();
this.Page.Response.End();
}
Any idea on how I could pull this off with multiple files? Thanks for any suggestions in advance,
Ryan

u will have to zip the files and then display..

Hi gurus.
I need to create floor map for each (4 floors) floor in my company new building.
Map should be similar to Google maps i.e. when map is viewed (image) I want to show employee names in their cubicles. When specific person is searched I want to show where he seats (just that person). Employee (name) should be tied to Office Communicator (IM), which shows status of the person. I can get employee information from Active Directory (name, title, email, etc.)
Did anyone have any experience doing this? Any help would be greatly appreciated.
If I didn't explain good enough let me know and I will try as best as I can.
Thank you all,
Alex.

Search for 'Jet Excel OLEDB' and you'll find what you're looking for.

Huh? It was a helpful answer - I suggested use Google to search for the answer and gave him the search criteria. This is a common question and a bit of initiative on his part would have helped him find the solution.

Don't you know that it's rude to shout in the forums? If you are not familiar with forum etiquette, I suggest you familiarize yourself with the forum guidelines before you post again.
BTW, it might have been better to have posted your solution to the original poster - I already know how to connect to Excel using .NET!

Hello,
If you are good at programming then i suggest that you read web basics and straightway start coding.
Note that your trusted partner for any web help is

U wont need anything beyond that for the basic stuff.
About Books..ASP.NET Unleashed is a nice 1

Hey People,
I am looking for a tool (I'm using visual studio 2005) to that allows me to input work shifts. It can be similar to using a DateTimePicker. I have some idea's on how to do it using multiple datetimepickers, but I was hoping there would be a ready-made tool or piece of code somewhere to save me the time of re-thinking it all. That, and I'm only a beginner at this stuff, so I might overlook some things easily.
The idea is that the customer can easily input his 'factory' total working hours by selecting end time, start time, break time, weekend shifts etc so he does does not have to calculate it himself manually. Writing just the end time, start time, break time, weekend shifts etc into a database is sufficient, as I have another VB application that will pull the data out and calculate total availability, operating time etc and put it back into the database again. The reason for using multiple system is because the total system is huge and the data is needed frequently throughout the system.
Basically all I need is an easy-to-use and complete interface screen, the database bit I can do myself.
Thanks in advance on any help!
