Hi, For the purpose of serial communication I am created two applications in vb6.0 and I am used SaxComm control for this purpose. I am deployed both applications in two different pcs and both pcs are connected with null modem cable. I want to assign the data entered in the text box of first application to the text box of second application. From the first application I am sending data using the following code to write data to a serial port. SaxComm1.output=Text1.Text 'Name of the text box is Text1 I am receiving data in the second application like below. In the receive event of SaxComm control I am written the following code for the purpose of receiving data. I tried this in two ways. First Way ------------- SaxComm1.InputMode = comInputModeBinary Dim Buffer() As Byte ReDim Buffer(SaxComm1.InBufferCount - 1) Buffer = SaxComm1.Input MsgBox (Buffer) Dim I As Integer For I = 0 To UBound(Buffer) - 1 Text1.SelText = str(Buffer(I)) Next I Second Way ---------------- SaxComm1.InputMode = comInputModeText Dim str As String SaxComm1.InputLen = 0 str = SaxComm1.Input Text1.Text =str when I want to assign it text box the data is not coming properly as how I am entered in the first system. in the first way when I entered HI it shown the data in the text box as 84. in the second way nothing is showing in the text box. I kept watch on str. the value of str is shown as like below "â‚¬â‚¬" what is the problem exactly and can anybody tell me what modification i need to do if I want to assign the text what I entered in the first application as its in the text box of second application?? when I used MSComm32 control I am able to do the same thing.I am getting issue with SaxComm control only. Thanks in advance.
