◆ sheetToParameter() [1/2]

GAMSParameter sheetToParameter ( QAxObject *  sheets,
string  sheetName,
GAMSDatabase  db,
string  paramName,
string  paramText,
GAMSSet  set 
)

Creates an 1 dimensional GAMSParameter and transfers data from an Excel sheet (horizontal ordered)

Parameters
sheetsThe sheets object of an open Excel workbook
sheetNameThe name of the sheet to be read
dbThe GAMSDatabase where the GAMSParameter is created in
paramNameThe name of the new GAMSParameter
paramTextThe explplanatory text of the new GAMSParameter
setThe GAMSSet for GAMSParameter dimension
Returns
The new GAMSParameter in the GAMSDatabase
