Accessing external files thorugh sap

[Former Member]

Hi there,

what I want to do is have a text file that contains information particular to that machine.

My Add on will read this when loading up to access the information is this possible and how would i add it?

I have tried hard coding it to C:\config.txt but the add doesnt seem to like an external file?

Any ideas.

Hi Matthew,

You don't mention what development language you are using. As far as I know, if you are using .NET then you could use the FileStream object to read/write to a text file (see MSDN for full details at http://msdn2.microsoft.com/en-us/library/system.io.filestream(VS.80).aspx).

Perhaps you could post an example of the code you are using?

Kind Regards,

Yes i'm using VB.NET, all i need is to read in three lines form a text file like so. This works as i've run it through the debugger, however SAP doesnt seem to like it when i add my program as an add on.

Try

Dim objReader As IO.TextReader = System.IO.File.OpenText("D:\SAP\Config.txt") 'easier to put in with other program then not set path

config1 = objReader.ReadLine

config2 = objReader.ReadLine

config3 = objReader.ReadLine

objReader.Close()

Catch ex As Exception

SBO_Application.MessageBox("There is a problem with the configuration file: " + vbCrLf + ex.Message)

End Try

Also rather than have a hardcoded path i would rather have something like .\config to make it more flexible is this possible?

Hi!

There is no problem with B1 when reading files or... doing smth

Try StreamReader.

This is my C# example how to read lines and add elements, split by "\t" to the arrays.

StreamReader sr = new StreamReader(termTransDir + termTransferFileName);

while (sr.Peek() >= 0)

{

string itmLine = sr.ReadLine();

ArrayList arrItem = new ArrayList();

arrItem.AddRange(itmLine.Split('\t'));

arrTransItemCodes.Add(arrItem[0]);

arrTransItemNames.Add(arrItem[1]);

arrTransItemEANs.Add(arrItem[2]);

arrTransItemSerials.Add(arrItem[3]);

arrTransQty.Add(arrItem[4]);

}

sr.Close();

hth!

thanks for the reply i've managed to get the file to read in now as an addon. however rather than having it hardcoded is there a way of having the it read the file in repect of where the file is? for example ./Config.txt?

do you know where it stores the root?

thanks Matt.

If i've understood u right, you wanna have a root of your AddOn?

If so, it's like that:

string filepath = Application.StartupPath + "
";

if (File.Exists(filepath + "Config.txt"))

{

// proceed your actions

}
