Difrents beetwin Exe and Htm?

Does anyone can explain to me why when I sending some txt or htm file from my computer to friends computer (they are connected over modem using MSComm) everything is all right, but when I sending some exe or mp3 file computer witch is receiving that doesn't receive even one bait?

HTM or text can be sent as ASCII, which is probably the default mode, but when youre sending pictures, music or exe's you need to use binary transfer. I dont know about the MSComm control, but its probably got a transfer moce property you can set.....

I am using binary mode

Transferring binary data over the mscomm control is very tricky, and unreliable. I suggest you use Base64 encoding to transfer binary data, like you do with email attachments. There are several free libraries for VB to accomplish the encoding/decoding process.
