I am trying to use a message assignment shape to create the output
filename for my message.  I want the filename to be a prefix plus the
input filename.  The input file filename is
"InFile(FILE.ReceivedFileName)".  I declare the variable "Prefix" and
then I use a Concat statement to splice them together.  Intellisense
doesn't indicate an error.  However, only the ReceivedFileName piece
shows up in the file name.  What am I doing wrong?  My code is
below:

Thanks,
Nathan
_________________________
SetFileName = InFile;
Prefix = "ABC";
SetFileName(FILE.ReceivedFileName) = System.String.Concat(Prefix,
InFile(File.ReceivedFileName));
__________
If the input filename is "SomeFileName.txt", I should get
"ABCSomeFileName.txt".  But I only get "SomeFileName.txt".

Hello.

Xlang puts restrictions on what you can do with a string.  When I have
needed complex logic, I have either called an outside .net component or used
a variable of type StringBuilder.

In your case, can you just add the string to the beginning of the other
string like this: SetFileName(FILE.ReceivedFileName) = Prefix +
InFile(File.ReceivedFileName));
You might have to set the context values to string variables first to get
this to work.

Hope this helps.

Ok.  I have built an assembly.  Note that I know very little about
object oriented programming and nothing about C# until a few weeks
ago.  It compiled successfully and I deployed it to the GAC.  I then
added the reference to it in the Solution Explorer.  But now when I
type the expression I get a "identifier expected" error in the
expression editor.

I want to get a file named "salestracing_042705.txt".

Here is my expression and the source code for the assembly:

Expression:
------------------------------
SetFileName = Claflin850;
FileType = "SalesTracing";
SetFileName(FILE.ReceivedFileName) =
NameOutputFile.NameOutputFile.(FileType);
-----------------------------

Assembly source:
----------------------------
using System;
using Microsoft.XLANGs.BaseTypes;

namespace NameOutputFile
{
/// <summary>
/// This class takes a string and adds "MMDDYY.txt".
/// </summary>
[Serializable]
public class NameOutputFile
{
//	public NameOutputFile()
//	{
//	}
public string NameTheFile(string FileType)
{
string OutputFileName;
DateTime dt=DateTime.Now;
string Date;

Date = dt.ToString("MMddyy");

OutputFileName = System.String.Concat(FileType, "_", Date,
".txt");

return OutputFileName;
}
}
}

Hello.

From what I can see you .net code looks great!  I do not think you need this
reference though: ‘using Microsoft.XLANGs.BaseTypes;”

In the expression editor, your last line should be:
SetFileName(FILE.ReceivedFileName) = NameOutputFile.NameOutputFile(FileType)
;
I think you have an extra “.”.  You probably have a red “!” on the s
hape?

If you continue to have problems, please send me Orch and .net code to me at
swthomas@NOSPAMbiztalkgurus.com (just remove NOSPAM part).

Hope this helps.
