About thin clients and mobile access
For example, for a MIPS IV processor running Windows CE 5.0 or later:
[…]\InduSoft Web Studio v7.1\Redist\WinCE 5.0\MIPSIV\Bin\
2. From that directory, copy the following files…
• IndHTTP.dll
• IndVkStd.dll
• ISSymbolCE.ocx
…and one of the following Virtual Keyboard layouts…
• VKEN.ini (for English)
• VKGE.ini (for German)
…into any directory in non-volatile memory on the Windows Embedded device. Make sure that all files are
stored in the same directory.
3. At the Windows command prompt, execute the following command:
regsvrce.exe "\ISSymbol_directory\ISSymbolCE.ocx"
For example:
regsvrce.exe "\Storage Card\ISSymbolCE.ocx"
4. Save the registry settings to keep ISSymbolCE.ocx registered when you reboot the Windows Embedded
device.
Windows Mobile / Pocket PC
1. Follow steps 1 and 2 of the instructions for Windows Embedded (above).
2. Run the program RegSvrCE.exe on the Windows Mobile device. While in the program, do the following:
a. Locate the file ISSymbolCE.ocx in the directory to which you copied it.
b. Select the Register option.
c. Click OK.
Tip: Your Windows Mobile device may not come with the program RegSvrCE.exe, because such
consumer devices (i.e., smartphones and PDAs) are typically not meant to be used like this. If
you need to acquire this program — or VBScript.dll, which is also left off most Windows Mobile
devices — then please contact Customer Support.
How It Works
After you open the Web browser, you must type the URL for one web page available in the Web Server station
(e.g., http://127.0.0.1/main.html) into the Address field. At this point, the Thin Client executes the
following process:
1. The Web browser downloads the HTML page of the screen you specified.
2. The Web browser checks for ISSymbol control registration in the local computer. If it does not find it,
the Web browser attempts to download the ISSymbol component from the URL configured in the project
(settings saved in the HTML page). Since the ISSymbol control is properly registered in the Thin Client
station, the Web browser loads it.
From this point on, ISSymbol takes over the communication with the server station, and the Web browser
is used only as a host for ISSymbol.
3. ISSymbol connects to the data server. You configure the data server IP Address in the project settings (Thin
Client on the Project tab of the ribbon). This setting is embedded in the HTML page.
4. ISSymbol prompts a window on the Thin Client, asking for the User Name and Password. The data you enter
is codified by Binary Control and sent to the server. The server station checks the validity of the data
