Hello Nathan. Thank you
I want to make a software that was able to communicate with any DMM that use LXI.
Im usin Visual C++ .NET and the IVI COm driver are by Agilent.
I think that the problem is that i would know the ProgID.
For Example the next code give me an error that says that the CLASS ID its not registred, how can i discover the PRog ID??
#include
"stdafx.h"
#import
"IviDriverTypeLib.dll" no_namespace named_guids
#import
"IviDmmTypeLib.dll" no_namespace named_guids
#import
"GlobMgr.dll" no_namespace named_guids
#import
"IviSessionFactory.dll" no_namespace named_guids
#import
"IviConfigServer.dll" no_namespace named_guids
//using namespace IVICONFIGSERVERLib;
int
main(int argc, char* argv[])
{
HRESULT hr;
char
nombre[56];
hr = CoInitialize(NULL);
if
(FAILED(hr))
exit(1);
printf("introduzca el nombre del nuevo hardware: \n");
scanf("%s",nombre);
getchar();
{
IIviConfigStorePtr cs(
__uuidof(IviConfigStore));
//cs.Detach;
try
{
// Deserialize the master configuration store.
cs->Deserialize(cs->MasterLocation);
try
{
// Create an empty Hardware Asset
IIviHardwareAssetPtr ha(
__uuidof(IviHardwareAsset));
//Set its properties
ha->Name = _bstr_t(nombre);
ha->Description = _bstr_t("Multimeter connected to the switch");
ha->IOResourceDescriptor = _bstr_t("GPIB::22::INSTR");
// Add it to the global hardware asset collection
printf("hasta aqui");
IIviSoftwareModulePtr sm(
__uuidof(IviSoftwareModule));
sm->Name =_bstr_t(nombre);
sm->ProgID=bstr_t("Jolin");
cs->SoftwareModules->Add(sm);
cs->HardwareAssets->Add(ha);
}
catch (_com_error e) {
printf("Add HardwareAsset failed.\n");
printf("Error description is: %s\n",(
char*)e.Description());
//printf("%s");
getchar();
}
try
{
// Create an empty DriverSession
IIviDriverSessionPtr ds(
__uuidof(IviDriverSession));
// Set its properties
ds->Name = _bstr_t(nombre);
ds->Description = _bstr_t("DriverSession for the system multimeter");
ds->Cache =
true;
ds->InterchangeCheck =

ds->QueryInstrStatus =

// Add the SoftwareModule reference to the Session.
printf("hasta aqui");
ds->SoftwareModule = cs->SoftwareModules->Item[nombre];
// Add it to the global driver session collection
printf("hasta aqui");
cs->DriverSessions->Add(ds);
}
catch (_com_error e) {
printf("Add DriverSession failed.\n");
printf("Error description is: %s\n",(
char*)e.Description());
getchar();
}
try
{
// Create the Logical Name
IIviLogicalNamePtr ln(
__uuidof(IviLogicalName));
// Set its properties
ln->Name = _bstr_t(nombre);
ln->Description = _bstr_t("The name used in the test program");
ln->Session = cs->Sessions->Item[nombre];
// Add it to the global logical name collection
cs->LogicalNames->Add(ln);
}
catch (_com_error e) {
printf("Add LogicalName failed.\n");
printf("Error description is: %s\n",(
char*)e.Description());
getchar();
}
// Overwrite the master with the modified configuration store
try
{
cs->Serialize(cs->MasterLocation);
IIviSessionFactoryPtr spSF(
__uuidof(IviSessionFactory));
IIviDmmPtr spDmm = spSF->CreateSession(nombre);
}
catch (_com_error e) {
printf("Serialize failed.\n");
printf("Error description is: %s\n",(
char*)e.Description());
getchar();
}
}
catch (_com_error e) {
printf("Deserialize failed.\n");
printf("Error description is: %s\n",(
char*)e.Description());
getchar();
}
}
//getchar();
CoUninitialize();
return
0;
}
And other question: its possible make a software that can discover what class of intrument have you linked at network??
Excuse me by my english, and thank you for your help
