Troubleshooting
A. The main features not supported by CEView are: DDE, NetDDE, ODBC, PasteLink, and a number of
functions.
Q. How do I show a splashwindow when starting a project in CEView
A. To enable your project to show a splash window during startup, add the following key to the device's
CEView.ini file:
[OEM]
SpashWnd = Path to bitmap File // default is Splash.bmp
SplashWndTime = Time in milliseconds // default is 1000
Q. How do I see runtime messages and errors on a "blind" Windows Embedded device — that is, a device that
has no display
A. If the device has a network connection, then you can use the Remote LogWin tool to view the device's
messages as they are generated.
You can also save the messages to a dump file (dump.txt) and access the file at your convenience. To create
the file, add the following key to the device's CEView.ini file:
[OEM]
BlindDevice = 1
Q. What are the main steps to create a Web-based application
A. Follow the procedure below:
1. Develop the project locally. Don't use features that are not supported by Thin Clients for the screens which
will be saved as HTML format.
2. After saving the screens in the standard format (Save in the Application menu), save the screens that must
be available for the Thin Client in HTML format (Save as HTML in the Application menu).
3. On the Project tab of the ribbon, in the Web group, click Thin Client.
4. In the Data Server IP box, type the IP address of the Server station (i.e., the station where the project is
running).
5. On the Home tab of the ribbon, click Tasks, and then set the TCP/IP Server module as Startup=Automatic.
6. Open the project tags database and set the option Server instead of Local in the Scope column for all tags
that must exchange value between the Server and the Thin Client station.
7. Verify the project (Verify on the Home tab of the ribbon) to update the HTML files with these new settings.
8. If there is no Web Server running on the computer, copy the program NTWebServer.exe from the Bin
sub-folder of the program directory into the Web directory (e.g., \project name\Web) and run it. The
path where this Web Server program is executed will be the root directory of the server. The Web Server is
necessary to export data (web files) in HTTP protocol to the Thin Clients.
9. Run the project on the Server station.
10.Using a browser (for example, Internet Explorer v4.1+SP1 or newer version) in the Thin Client station,
type the URL address to download the screen that had been saved in HTML format (for example,
http://ServerIPAddress/ScreenName.html).
Note: The Thin Client requires an ActiveX component ( ISSymbol.ocx ) to handle the screens on
the browser. If the Thin Client is connected to the Internet, this component is downloaded and
registered automatically. Otherwise, it's necessary to copy it to the \OSPath\System32 directory of
the Thin Client and register it by the command regsvr32 ISSymbol.ocx. This file can be found in
the \BIN folder from the IWS installation directory.
Q. How do I maintain communication between a Thin Client connecting via proxy and a Web Gateway
application running on Microsoft IIS
