int channel

*this line give me the error

Getdata(0, &channel, (unsigned char*)dataBuf, 1000);

that's not vb.net. this is the vb.net forum

[jmcilhinney]

That's not VB.NET code so the VB.NET forum is obviously not the place for this question. Please use the Report Post icon to send a message to the mods and ask them to move the thread to the appropriate forum.
