posted October 31, 2007 12:37 PM I am using the TCP examples to build on in order to make some test applications. I have added to the Client sample so that it will wait until it has the complete message before processing it. The reason being, that i am sending xml as a string. Until a complete xml document is received, it will not be able to be loaded. So on the tcp.receive event, i am using the Search method to ensure i have the end of a document before continuing. This is used on the webserver example. heres my Receive event: Private Sub Tcp1_Receive() Dim r As String Dim rl As Integer Dim Request As String Tcp1.Receive r ' Receive the data rl = Tcp1.Search(r, "</message>") If rl > 0 Then Request = r Call ProcessXML(Request) End If End Sub I am searching received data for "</message>" which is the tag that marks the end of the XML string being received. The problem is that the search method never finds "</message>" in string 'r', even though in debug, it clearly is there. Here is an example of the XML being sent as a string: 'start message strData = "<?xml version='1.0'?>" strData = strData & "<message>" strData = strData & "<msgtxt>TESTMESSAGE</msgtxt>" strData = strData & "</message>" 'end message The only difference i can see between this and the webserver example is that the webserver uses the client class for each session, and session_receive events. Any help or advice appreciated. Thanks |

posted October 31, 2007 1:08 PM I think i may have figured it out. In the receieve event, i have use the receive method right before the search method. Tcp1.Receive r ' Receive the data rl = Tcp1.Search(r, "</message>") I guess the receive method was flushing the buffer, meaning the seach had nothing to search? Thanks |

posted November 1, 2007 2:22 PM Hello, Both Receive as well as Search methods flush the buffer. I would suggest you to please take a look at one of our sample (Blaster) which uses Search method to search for a specified token. Here is the default location of this sample: C:\Program Files\PowerTCP\Winsock for ActiveX\Samples\Vb6\Tcp\Blaster Best Regards, Amit ------ |
