hello
i used from Array.Resize,but i could not arrange its arguments
please help me that how can i arrange its arguments?
thanks
public byte[] ExtractBytesFromStream(Stream stream, int dataBlock)
{
int totalBytesRead = 0;
byte[] data;
try
{
while (true)
{
Array.Reverse(data, totalBytesRead, dataBlock);?
Array.Resize(data, totalBytesRead + dataBlock);?
int bytesRead = stream.Read(data, totalBytesRead, dataBlock);
if (bytesRead == 0)
{
break; // TODO: might not be correct. Was : Exit While
}
totalBytesRead += bytesRead;
}
Array.Reverse(data, -1, totalBytesRead);

First of all, you don't even have an array at all. You have to create an array before you can resize it.
Why are you reversing the data in the array? If there is a reason to revere any data in the array, you can't reverse data that isn't even in the array yet, and there is no reason to reverse a bunch of zeroes. Also, you can't use -1 as starting index when reversing a part of an array.
You have to resize the array to the size of the actual data read before you return the array. Now you are returning an array that is larger than the actual data read, and you don't return how much of the array that contains valid data.
Despite everything, the person most likely to be fooling you next is yourself.

You can use regular expressions to validate the supplied text is in a valid email format.

You are expecting too much. You won't know the mail bounces untill you send it.

You won't know until you actually try to send the email whether or not it bounces. You can use regular expressions to see if the email is in a valid form or not.

You don't find what you are asking for. Only way is to send email, get a confirmation by asking users to click on confirm email link.

I second that. Sure there's regular expressions to check for any silly email addresses, but one has to actually try and send an email to see if it is indeed valid or not. The confirmation approach works well, too

Where there any ASP.NET changes from 2.0 to 3.0/3.5?
Or does 3.0/3.5 simply represent the newer .NET technologies - WPF/WCF/WF?

This is pretty straight forward task, and what have you done so far?

How do I take the database Visual Studios .net creates for user logins and upload it to a server that will host my website? I’m a very, very new user. I have been learning ASP.net through books and websites. I found many place that teach me how to create the login. It runs fine on my computer but I can’t find any information about how to transfer it to a real website and link my code to that new database. Thanks to anyone that can help.

It'll be better if you make your own custome control then you would be having meore flexibility on that

you need also the data base server for that. you just take a backup and restore the database on web database server from where your web server will connect with data base server.

Thanks for the answer. I think I understand what needs to be done. The problem I have is, how to do that. Visual Studios .net creates a file called ASPNETDB.MDF stored on my harddrive. I purchased web space for a hosting company. The host allows me to create a MS SQL database from an interface page. What do I need to do to transfer this database to hosting companies server? Then connect to this database with my asp.net code? I'm running a XP Pro machine with Visual Studios 2005. I'm very new to programming and many instruction are above me head. Please help me understand what program to use and how to do it.
Thanks for the help.

You can always go into SQL Server Management Studio and generate a Create Database script. Take the generated script and run it on the hosting account.

for updating the data fields in a grid view , u may hav to do a little
changes in the properties of the Grid view.
first, u select the data source of the Grid and after putting the update query with the parameters , Go to the Grid view properties and select the "DatakeyNames" prop. and then frm that select ur "id field" for it.
After that u select the smart tag of Grid view : check the "Enable Editing" and then go for "Edit Colums".
From that , first uncheck "Auto-gen. fields" check box then add from
"Command fields" the Edit,update etc. then add all the "Bound fields "(if u can't find it just refresh schema). Then finally, select the added bounded fields and put the fields to edit and make its "readonly" prop. as false and others must b true.
