Parameters

  • DialogTitle
    Type: Text The text displayed in the title bar of the Open dialog box.

    Note

    This parameter is not supported by the Microsoft Dynamics NAV Web client or Microsoft Dynamics NAV SharePoint client. The title is determined by the end-user's browser.

  • FromFolder
    Type: Text The path of the folder that is displayed in the File Open dialog box. This is the default folder, but the user can browse to any available location.

    Note

    This parameter is not supported by the Microsoft Dynamics NAV Web client or Microsoft Dynamics NAV SharePoint client. By default, the browser uses the folder that was last accessed.

  • FromFilter
    Type: Text The type of file that can be uploaded to Microsoft Dynamics NAV Server. In the Microsoft Dynamics NAV Windows client, the type is displayed in the upload dialog box, so the user can only select files of the specified type. For the Microsoft Dynamics NAV Web client and Microsoft Dynamics NAV SharePoint client, a user can try to upload any file type but an error occurs if the file is not the specified type.

  • FromFile
    Type: Text The default file to upload to the Microsoft Dynamics NAV service. The name displays in the dialog box for uploading the file. The user can change the file.

    This parameter is not supported by the Microsoft Dynamics NAV Web client or Microsoft Dynamics NAV SharePoint client.

  • NVInStream
    Type: Variant The InStream that is used to send the file.

If you omit this optional return value, then a run-time error occurs if the record cannot be found. If you include a return value, then you must handle any errors.

true if the file was uploaded; otherwise, false.

Remarks

Note

This function is not supported by the Microsoft Dynamics NAV Web client on devices that run Apple iOS, such as iPad. The dialog box for uploading a file displays in the Microsoft Dynamics NAV Web client, but it is disabled and the user cannot select a file.

The maximum size of the file to be uploaded is specified by the MaxUploadSize setting in the CustomSettings.config file. The setting is specified in megabytes. For more information, see Configuring Microsoft Dynamics NAV Server.

In Microsoft Dynamics NAV, the business logic runs on the computer that is running Microsoft Dynamics NAV Server and not on the client. Files are created on Microsoft Dynamics NAV Server and not locally on the client computer.

Use UPLOAD Function (File) and UPLOADINTOSTREAM Function (File) to send a file from the client to Microsoft Dynamics NAV Server.

Use DOWNLOAD Function (File) and DOWNLOADFROMSTREAM Function (File) to send a file from Microsoft Dynamics NAV Server to the client.

We recommend that you use the functions in codeunit 419, 3-Tier Automation Mgt., to upload and download files.
