How do I create a file using Alchemy?

Question

I have C++ code that uses the following method to create a file: open(filename, access, perms)  to create a file, just a standard C++ method from <fcntl.h> library. It works perfect in C++, it creates the file, however, if I compile it into a swc file and use it in my Flex project, it does not create the file. Is there any way I can use that method, compile that C++ code into swc and use it in Flex project and still be able to create a file?

Hi Jim,
That's right.Your understanding on my question is right.
I know to write a file, we need record,file and sql object to work.
record creates and instantiates the rowset for that record.
sql fetches all fields using the by passing the record parameter and %selectall(:1) where bind variable is record name.
File object helps to create ,open write and close the file.
I wanted to know How could implement/integrate the rowset feature to filter and extract the data specifcally.Since I am new to App engine.I checked out people books where they have mentioned the syntax but not the integration.
Regular code that i am trying with the above objects is like this below:
Local File &MyFile;
Local Record &rec1;
Local SQL &SQL1;
/*Create Instance of Record */
&rec1 = CreateRecord(record.tc_help_me_tbl);
&MyFile = GetFile“c:\temp\help_me.txt”, , “A” %FilePath_Absolute);
&MyFile.setFileLayout(FileLayout.help_me);
/*Create SQL object to populate rowset */
&SQL1=CreateSQL(“%selectall(:1)”,&rec1);
While &SQL1.Fetch(&rec1)
&MyFile.WriteRecord(&rec1);
End-While;
&MyFile.Close();
provide me the rowset code by integrating in between them(fill it with one field)
Thanks and Regards
