int DoMethod( LPCSTR lpcszCmd, LPCSTR lpcszArg, double * pdVal = NULL);

int DoMethod( LPCSTR lpcszCmd, LPCSTR lpcszArg, string & strReturn);

Parameters

lpcszCmd: [input] Object method name, case insensitive
dwCntrl: [input] method's input if require
pdVal: [output] return value, if index variable type, 1 offset, like Labtalk

lpcszCmd: [input] Object method name, case insensitive
lpcszArg: [input] method's input if require
strReturn: [output] return value, if index variable type, 1 offset, like Labtalk

lpcszCmd: [input] Object method name, case insensitive
lpcszArg: [input] method's input if require
pdVal: [output] return string value

Return

Returns 1 if lpcszCmd is a valid method and 0 if it is not. -1 if error occurs If pdVal is NULL will return the method return integer value directly
