5. Encapsulate the write and read operations of VISA.
1) Encapsulate the write operation of VISA for easier operation.
private void Device_Send(string Cmd)
{
string strCmd = Cmd + '\n';
long lDevReturn = 0;
lDevReturn = viVPrintf(g_i32VisaIO, strCmd, 0);
if (lDevReturn < 0)
{
MessageBox.Show(this, "Failed to send commands！ ", "Tip",
MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{ }
}
2) Encapsulate the read operation of VISA for easier operation.
private string ReadFromDev()
{
string strReturn = "";
byte[] temp = new byte[10000];
long lDevReturn = 0;
lDevReturn = viScanf(g_i32VisaIO, "%t", temp);
if (lDevReturn < 0)
{
MessageBox.Show(this, "Read fail! ", "Tip", MessageBoxButtons.OK,
MessageBoxIcon.Information);
return strReturn;
}
else
{ }
