In one of my VB6 Application, I have used MSXML2.ServerXMLHTTP50 Object to send XML message to other application(Tally7.2 Accounting Software) and receive response in XML from it. I communicate it by giving Computer IP address and Port Number of Tally.The Code is
Dim serverHTTP As New MSXML2.ServerXMLHTTP50
ReqListOfCmp = _
"<ENVELOPE>" & _
" <HEADER>" & _
" <TALLYREQUEST>Export Data</TALLYREQUEST>" & _
" </HEADER>" & _
" <BODY>" & _
" <EXPORTDATA>" & _
" <REQUESTDESC>" & _
" <REPORTNAME>List of Companies</REPORTNAME>" & _
" <STATICVARIABLES>" & _
" <SVEXPORTFORMAT>$$SysName:XML</SVEXPORTFORMAT>" & _
" </STATICVARIABLES>" & _
" </REQUESTDESC>" & _
" </EXPORTDATA>" & _
" </BODY>" & _
"</ENVELOPE>"
PortNo = txtPortNo.Text
serverHTTP.Open "POST", "http://localhost:" & PortNo, False
serverHTTP.send ReqListOfCmp
respListOfCmp = serverHTTP.responseText
Problem is That now I want to do the same thing in C#. What class i have to use in place of MSXML2.ServerXMLHTTP50. As I have to communicate using XML over Http with a Non DotNet Application(i.e Tally). I have tried to search with Remoting but as Server is one of the Non-Dotnet application I am not able to do it.
Plz help me , its urgent..................Thanks in Advance

I have a DataGrid in a web page which displays results. Now I
want to show some string contents instead of numeric values of a field.
For example I have a field "Type" with (0/1) values and I want to show
(Individual/Company) instead of (0/1) numbers.
I'm using C# .NET
Thanks.

Is there an easy way in C# to quary all tables from a database and write them to a XML-file (basically turning a database into XML)?

If you get get the database into a dataset (which is very highly likely  ) then you can use the DataSet.WriteXml function, does exactly what it says on the tin

It's tedious and somewhat cruel, most matches ending in a draw as no participant is able to find anything helpful. - Shog9

This is only a design thread , its not much of a question , I just want to see what other people think is the right way..
Lets say you have 2 interfaces that have a 1-1 relation to eachother.. those two interfaces that can never be used w/o the other.
(eg in a model view presenter scenario where you have a view interface and a presenter class)
normally when a class might be used by multiple consumers it would be correct to use delegates/events to notify the consumer when something have happened.
however in a 1-1 scenario, you could just as well let them be aware of eachother and simply let them call specific methods in eachother.
What is your take and arguments on this?
I myself consider the last approach the most correct from a business perspective, since it does what it should and result in far less code that is still easy to maintain and have no drawbacks over the event based approach.
but the event based approach somehow still _feels_ like the correct way... maybe because it often is the correct way , but in other scenarios?
ideas and arguments please

Can you guarantee that no class in the future would like to be notified of the change? If so then strongly couple them, otherwise you may want to stick with the event approach to allow others in future to subscribe and be notified.
I prefer open approaches that let me hook on functionality later, but I sometimes closely couple classes if im sure its right.

Keep it simple, if it needs to accomodate more complex scenarios in the future it can be modified. Never go more complicated than necessary. Then again, what's the harm in adding events, even if you don't currently use them? My philosophy anyway... And Kent Beck would likely agree.

I have an array of objects that i want to add to a DataGridView.
The objects have properties Header, Status, Date and Id (that in this case matters).
Now i only want to show Header and Status in the DataGridView, but i still want the whole object to be bound to the row so that i dont loose the identification (Id) to the object in the array.
How do i do this?

Maybe this artical helps

Also, if you don't want to show some column in runtime, simply hide it (.Visible = false).

Hello Sir
I want to know what is a Batch files.
How can it work and how can we make it.
Practic Makes Man Perfect

Batch files are files in Windows in which you write a batch(sequence) of DOS commands those are executed one by one when you run the batch file. There are also some conditional constructs like if, else for batch files too.
They can be constructed by simply making a notepad or anyother text editor file and changing its extension to .bat. A batch file can be executed by simply clicking on it.

Is there an easy and efficient way in C# to read a file in blocks, remove all carriage return & line feed characters from the read block and write the remaining block into another file?
I've tried FileStream, StreamReader and StringBuilder without success. I'm obviously missing something here, being a newby in C#.

Hy,
Try this:
//reading from the file.txt
FileStream fstream = File.Open("file.txt",FileMode.Open);
byte []buffer = new byte[fstream.Length];
fstream.Read(buffer,0,buffer.Length);
string message = System.Text.Encoding.ASCII.GetString(buffer);
message.Replace("\n","");
fstream.Close();
//writing fileSave.txt
fstream = File.Open("fileSave.txt",FileMode.Create,FileAccess.Write);
buffer = System.Text.Encoding.ASCII.GetBytes(message);
fstream.Write(buffer,0,buffer.Length);
fstream.Flush();
fstream.Close();
You use the Replace method to replace the CRLF. If this doesn't work only with replacing '\n', try replacing '\r' too.
There could be another way in this example. In the byte array "buffer" search for 13(ascii decimal value for CR) and 10(LF) values that are sequential. If you find these values delete them from the byte array

If you use the ReadLine method, it reads up to a newline, but does not read the newline.

Hi,
When adding anything new record, for example a new car, is it always wise to validate the input parameter?
The code that I have is as follows:
public static int InsertCategoryGroup(Car objCar)
{
// Validate parameter
if (objCar == null)
throw (new ArgumentNullException("objCar"));
}
Is this the correct way to do it, or is there a better way? Am I throwing the correct exception, or is there more that I need/can throw. Please can someone comment.
Regards,
ma se

Hy,
Throwing exception is a good way to validate parameters. You could try to create new Exceptions. If you don't want to write code that catches exceptions you can validate the parameter in the InsertCategoryGroup function and if the parameter does pass the validation step just return an error code (like -1).

Awful advice in .NET! Error codes mean nothin, have no context, no stack trace no message. Use exceptions!

Hi,
I agree with you.
This is how I code. I work like this:
.aspx page --> BLL class --> DAL class --> BLL class --> .aspx page
In my stored procedure I usually do a test to see if a record has been inserted or updated. To test for an inserted record success, my code is:
-- Check for insert error
IF (@@ERROR <> 0)
BEGIN
SET @ErrorCode = -1; -- SQL Server error
GOTO CleanUp;
END
-- Commit transaction
IF (@TranStarted = 1)
BEGIN
SET @TranStarted = 0;
COMMIT TRANSACTION;
END
RETURN 0;
So if there happens to be an error it will return a -1. Now in my returned parameter, how do I throw this exception based on -1???
Please advise.
Regards
ma se

The way you are doing it is spot on, and is also the MS best practice way, provided you always expect to have a car object supplied to your method.
The golden rule is that exceptions should only be used for exceptional circumstances, and not as a general means of controlling execution flow.

Rob Philpott.

I'm using the method NetworkStream.Read to receive data from Network.
But this method is a blocking method. That's why I put this
method in a new thread.
If there are no data, then it will be halted here (NetworkStream.Read).
How can I abort this method, for example if I close my application ?
