if you want to upload files to a server why not try using FTP

If only MySelf.Visible was more than just a getter...

Hi musefan,

Thanks your response. Unfortunately, it not as simple as just placing a file on the server. I need to upload the file into the SharePoint services which handles security, and attaches metadata to the file, along with some categorization functionality, file revisionining, etc.

I'm typically a PHP developer so this is a whole different realm to me. Is there a way I could toggle between network settings, for example if one machine is connected to a network where the IP address is automatically generated then connecting to a completely different network where the IP address has to manually entered, is there a way C# handles the TCP/IP settings to toggle between automatic and manual? If there is a way are there any resources out there I could read up on.

Thank you,
I apologize for the ambiguity.

StreamReader.ReadLine()

Hey I have a StreamReader whose underlying stream is a NetworkStream, when I read from it, it throws a FormatException.

What could be the causes?

I am writing "r\r\n" to the NetworkStream and then call the StreamReader.ReadLine() method on the client side and it throws this exception.

What am I doing wrong?

You possibly got an incomplete packet of data? You possible only got a partial line of data from the network stream. Without seeing the code that handles this, it's impossible to say.

You're writing "\r\n" to the network stream server side? Are you not using a StreamWriter with WriteLine()?

Hey guys It wasn't the readline() which was causing the exception Smile | :)

I figured it out it was the Convert class Smile | :)

which couldn't convert.

Thanks anyways

yeah, having two consecutive \r didn't make much sense, did it?
one got eaten by ReadLine() as part of Environment.NewLine, and the other was disliked by Convert Big Grin | :-D

Without seeing the code, it's difficult to say where you messed up. But, it looks like you're trying to convert an enumeration to a Image object, which obviously won't work.

So you made your own WindowsApplication1.encode.Image type (a class, a struct, an enum, can't tell without seeing your code), and now you are hoping it can be used where .NET is expecting a real image (that is a System.Drawing.Image)??

Is there encode.Image somewhere in your code?
The pieces you have shown are insufficient to diagnose.

SQLServer Query Problem - Solved ... thx

benny merkle10-Feb-09 4:50

10-Feb-09 4:50

Hi

I have a problem and maybe someone of you can help me :`|

I send a query to a SQL Server 2005

SingeltonConnection singletonCon = SingeltonConnection.GetInstance();
SqlConnection sqlCon = singletonCon.SqlConnection;

sqlstmt = "Select * From dbo.Team FOR XML RAW, ELEMENTS";

SqlCommand cmd = new SqlCommand(sqlstmt, sqlCon);

normaly i do it this was (with normal select * from dbo.Team querys)
cmd.ExecuteNonQuery();
while (reader.Read())
{
String tmp = reader[1].ToString();
...
}

but now i get an error (Index was outside the bounds of the array. )

SqlXml xml = reader.GetSqlXml(0); reader doesnt solve

So what is the return Type of my Query and how can i work with it?

thanks for your help

musefan10-Feb-09 4:57

10-Feb-09 4:57

you have an index out of bounds error, whats that got to do with return type of query?

If only MySelf.Visible was more than just a getter...

benny merkle10-Feb-09 5:09

10-Feb-09 5:09

hm i dont know how to handle the return of the query
i dont know how i get my XML data ... and normally the result should be in reader[1] or ???

musefan10-Feb-09 5:17

10-Feb-09 5:17

this is the code i would use to write an xml document, you choose if you want to use it or not

SqlConnection conn = new SqlConnection("ConnectionString");
connection.open();

string query = "Select * from table";

SqlCommand cmd = new SqlCommand(query, conn);

SqlDataReader sdr = cmd.ExecuteReader();

DataTable dt = new DataTable("tablename");

dt.Load(sdr);

dt.WriteXml("outputFilePath");

oops, dont forget to close the connection

If only MySelf.Visible was more than just a getter...

the FOR XML option returns the data in one, zero-indexed, column. reader[1] accesses a column that would not exists. reader[0], however, would refer to the xml data returned in the query.

Also, as a personal nit to pick. reader[0] will contain an object based on the type. While calling ToString is effective, it is not correct. (string)reader[0] and reader.GetString(0) would be more correct.

Need custom software developed? I do C# development and consulting all over the United States.

If you don't ask questions the answers won't stand in your way.

Doing a job is like selecting a mule, you can't choose just the front half xor the back half so when you ask me to do a job don't expect me to do it half-assed.

benny merkle10-Feb-09 23:05

10-Feb-09 23:05

okay

i tried string x = reader.getString(0); and get this error
Invalid attempt to read when no data is present.

my query is okay i tested it in SQL Management Studio ... so where did i made my mistake??

Ennis Ray Lynch, Jr.11-Feb-09 2:45

That error usually occurs when there is no data in the data readers, ie, dataReader.Read() did not return true. It is probably a small error in your code.
