I am teaching myself vb.net and wanted to change this code to have an embedded mail.boby from a text file instead of the file attachment. can someone help? Code spippet below and where I need help is mail.Body = (<span style="color:#a31515 "tracertALL.txt")
that just puts the name of the file NOT the contents of the file. This code is a CMDWrapper that runs a batch file and I want the contents of a trace route that is pipe to a file >> tracertALL.txt . thanks any help is greatly
appreciated!
