hello,
I'm trying to control an attenuator with visual studio 2010 in C++ whith VISA library and i want to permit the utilisator to choose the level of attenuation.
to realize this i need to send to the attenuator a specific command which is " A050," if i want the attenuation is 50 dB.
So i create this CString:
CString attenutation=( Cstring ) "A0" + value + (Cstring) "," ;
where value is a Cstring wich depend on utilisator's attenuation choice.
to send this command i must use viWrite() wich requires a ViBuf in entry, so i need to convert the Cstring attenuation in ViBuf .
help me please and excuse my English !
*Pardon my french
