Question

I need to customize AX to load an arbitrary file with arbitrary size and save it to database as a container field. I also need to read back from that container field and write the content into a file, which should contain exactly the same file content as before load.

I had tried with BinaryIO, unfortunately with no luck

Answer 1

The answer to this question applies.
Especially you should use the system class BinData and the methods loadFile and saveFile
.

Example: this job copies the notepad program to a temporary directory.

static void BinDataTest(Args _args)
{
    BinData b = new BinData();
    Container c;
    b.loadFile(@"C:\Windows\notepad.exe");
    info(int2str(b.size()));
    c = b.getData();
    b = new BinData();
    b.setData(c);
    info(int2str(b.size()));
    b.saveFile(@"C:\Temp\notepad.exe");
}
