How to return in a method before transaction?

Question

Hi,

I have a method which returns 1 or 0 after some transactions. I wonder if there is a way to return 1 or 0 before the transactions? The reason is because there is a mechanism that waits for this return value and it is more important than the transaction itself.

This is my sample method:

public string retDrawProgram(System.Data.DataSet dsDrawProgram, string sDrawNumber, string sDataRevision)

{

        //Here is my transactions

return 1;

}
