Hi Friends,
i want to send key-value pair values on HTTP Request using C#. If anybody know how to send key-value pair values then please send me hint.
Regards
Bill

The HTTP protocol is well documented.
How does this question apply to C#? Are you using a .NET
HTTP class?
If you're using HttpWebRequest you can use its Headers property
to get a WebHeaderCollection. WebHeaderCollection.Set() can be used to
add header key/value pairs (if that's the key/value pairs you're
referring to).

I have an oracle function.It works fine when it is static.
If i create the same function dynamically though asp .net code the error comes.
I tried this code ALTER FUNCTION Group_concat COMPILE
This code works manually.But in the run time it does not work.
Give me solution if anyone knows.
Thank you

What error? And what code? (Describing the code does not count)
|

Few issues:
- why do you want to compile the function from code. You may run into trouble with that
- most likely your connection hasn't got enough privileges
- if you need to create a pl/sql block at runtime, perhaps you could use anonymous blocks
The need to optimize rises from a bad design.

hi every body...........i have a problem.i have a web page in which i m uploading an video file by using fileupload control.......before uploading that video file i m checking the size of that video file by the variable FileBytes.then i m checking it with the drive free space .......but this exception named System.OutOfMemoryException occured when i upload the video file of more than 500 MB...the coding i m using is ..........
byte[] FileBytes = FileUpload.FileBytes; // the problem is coming in this line as byte is small datatype for the video file of more than 500 MB
long freespace =drInfo.AvailableFeeSpace;
i want to upload video files of more than 500 MB ...it may be in GB's also

You are trying to store half a gig in RAM. Using this technique you will need sufficient RAM to achieve yout task and allow everything else that is running to continue to do its job.

i have sufficient RAM (2 GB) to store these files.but my problem is that whem i m checking the size of the file i m uploading i have taken the datatype as byte which is not sufficient for the files of size more than 500 MB..what data type can i use to store the size (in bytes) of more than 500 MB....
|

Can you upload without loading the entire file into RAM
(i.e. upload in chunks)?

Error
Specified argument was out of the range of valid values.
Parameter name: index
while i'm loading the page, error will come in this code
protected void grdEncounter_RowDataBound(object o, GridViewRowEventArgs e)
{
GridViewRow grdEditRow = e.Row;
if (grdEditRow.RowType.Equals(DataControlRowType.Header))
return;
grdEditRow.Cells[2].Text = grdEditRow.Cells[2].Text.Equals("1") ? "Yes" : "No";
//error comes under above line
}
thanks in advance

It looks like you're trying to access the 3rd cell (zero based index) which doesn't exist as the error message says.
set a breakpoint on that line and examine the cells Count property.

Ok so im making a program in C# to be a desktop based version of our AJAX chat on our site. The AJAX chat reads messages and other info from the main SQL database on the site.
Now my program does the same. BUT the problem is that the program is still decompilable(which means that anyone can get our SQL username and pass).
So how do people normally stop this?Surely im not the only one making a program that has sql info in it?
Now i first thought I could just use an Obfuscator but after reading around it seems that even that will only ward of beginners.
Please help  thanks!

Have you never heard of a trusted connection?

I use trusted connections.

No, i havent :-/
Are you talking about web services?
thanks

No, I'm not talking about web services.
A trusted connection is one where the SQL Server accepts your current Windows Domain login to connect to the database.
Remove the user name and password from your connection string and replace with Trusted_Connection=yes
For more information about the various ways you can connect to databases see Connection Strings[^]

thanks man
EDIT: hmmm it seems like this would require me to add every user that uses the program to the database(well their windows login)? This is possible as there are a couple thousand users
|

You can add windows (NT) groups rather than individual users, that may help.

Well that doesnt really help because I have no clue who the users will be? Think of it like CodeProject making a windows based MessageBoard viewer...they dont have any idea what users are going to be viewing their program. So they would have to have SQL info in the program, but then would be scared that someone would decompile it and get their SQL info..

Then you (don't) use SQL's built in security to lock their access down to a couple of stored procedures.
Use a webservice, and give the webservice access to your database server. Letting random people on the internet connect directly to your server is just asking to be owned, unless you know exactly what you are doing.

Well, unless its an internet program (in which case you wouldn't be able to assign individual users 'on the fly' anyway) surely you have some internal security policies, and I bet they include Windows groups, otherwise you are wide open to abuse. As a contractor I have worked at many large multi-national financial companies, all of which use Windows groups as one form of application/database security. The only time I have seen anythng other than trusted connection (and within that the groups are only assigned the minimum permissions required) is with inter/intranet applications where sql server resides on a different physical server to IIS and you have the classic 'double hop' problem.
Anyway, its up to you, but I suggest you read up on SQL Server security before making a final decision, as whatever the connection method you need to enfore security within the server.

The problem is that it is an internet application...
Im thinking of just using Web Services.

Thats 1 way. If you had said that in the first place though you would have got more relevant advice. An internet appication (unless running under a VPN or similar) obviously cannot use windows authentication, so your choices become more limited.
