Hello all,
I need to cross reference data between 2 tables.
First I query table 1 and i get the result token.destination as a pointer data.
Then I need to query table 2 based on token.destination as a primary key.
The problem is that token.destination is a pointer and in table 2 I only have string data.
Thank you very much.
Regards,
The method getpath(..) transforms the pointer to a string.
The method find(string path) transforms the string path to a pointer.
@Joerg Vogel What if I am writing the pointer into a label and then want to read the pointer value into a string? I have a pointer like "/Station3A" and want to read last letter of the pointer into a string. I assume there should me something like label.str[-1] but I think C++ will have different syntax.
@Niket M First you want to get the name of the object stored on the pointer label, and then you can use the string.substr() method to get the last character in the string like this:
string myName = token.Station.name; return myName.substr(myName.length, 1);
