How to upload client file to server?

Question

I need to create form to upload file from client side to server in AX 2012 R3 using X++.

Can some one give me link / example regarding this issue?

I try to search and find that I can use class SysFileStoreManager, but still confused how to use it.

Answer 1

You can find example use of SysFileStoreManager using the Cross-reference Tool. I find it a bit bloated.

You can do this:

static client container getPackedFileClient(FileName _fileNameClient) 
{
    BinData binData = new BinData();
    binData.loadFile(_fileNameClient);
    return binData.getData();
}

This is the SysFileStoreManager.getPackedFileClient method, but without the protected keyword.
To save the file:

static server container saveFileToServer(container _packedFile, Filename _filename)
{
    #File
    BinData b = new BinData();
    b.setData(_packedFile);
    new FileIOPermission(_filename, #IO_WRITE).assert();
    b.saveFile(_filename);
}

This is SysFileStoreManager.copyFileToClient_Client adapted for general use. You can the call the methods in sequence:

saveFileToServer(getPackedFileClient(clienFileName), serverFileName);

The file content is transferred from client to server using a container.
