Today, when I was written in the process, I was actually set for a long time. I was confused for a long time. When I read the dbparm value from the INI file, the program was executed on the application error (unfortunately, I don't know how to upload pictures, Otherwise, let's take a look at it), whether it is in the PB environment or compiled. It turned out to have a string value in the dbparm parameter, and later set DBPARM to "", it is normal. It doesn't matter if it is normal to change the DBPARM parameters after normal. It's strange!
This small problem didn't care, I don't know if you have encountered it before? Too strange!
