Error in the Web Service

[Aashutoshkumar]

Hi All, I have a problem in my web service application. I have created the web service in visual studio 2005 in which a method ReceiveMsg(string strMessage) accept the string(in Xml format) from the client and created the xml file. The web service is hosted on the IP(.203) , when I access this service from another IP(.73) it working fine and return “SUCCESS”. But when the client accesses this service they receive the “Fail” message. I have created the log file for this method. When client access this method a message “string instance not set to an instance of the string” is inserted into the log file. Following is the code of the ReceiveMsg(string strMessage) method. [WebMethod] public string ReceiveMsg(string strMessage) { string strFinalResponse = null; try { strFinalResponse = "SUCCESS"; intNo++; // this is static variable. string strdocPath; strdocPath = "C:\\RQFEED\\RQ"+intNo+".XML"; Byte[] docbinaryarray = Encoding.GetEncoding(1253).GetBytes(strMessage); FileStream objfilestream = new FileStream(strdocPath, FileMode.Create, FileAccess.ReadWrite); objfilestream.Write(docbinaryarray, 0, docbinaryarray.Length); objfilestream.Close(); CreateLogFiles Err = new CreateLogFiles(); Err.ErrorLog(Server.MapPath("Logs/ErrorLog"), strMessage); return strFinalResponse; } catch (Exception ex) { strFinalResponse = "FAIL"; CreateLogFiles Err = new CreateLogFiles(); Err.ErrorLog(Server.MapPath("Logs/ErrorLog"), ex.Message); return strFinalResponse; } } Please help me as asap.
