Creating an Psion Tecklogix Scan Gun App

In 4 simple and easy to follow steps:

Step 1: Getting Psion Resources

You will have to register to get access to the page.
(https://teknet.psionteklogix.com/ptxCMS/Teknet.aspx?s=us&p=DevKits)

Download and install their "Mobile Devices SDK"


Step 2: Create Project

If you go to the "Smart Device" section, you will notices a "Psion Teklogix Device Project". This add the Psion TeklogixNet reference and also the PtxSdkCommon.dll in the root directory, which is a dependency when running your app on device.
















Step 3: Add Items to the Toolbar, if needed

Right-click on the Toolbar, and select Choose Items.
Browse to C:\Program Files\Psion Teklogix\Mobile Devices SDK V3.1\DotNet2 and select the PsionTeklogixNet.dll

This should add:




If not already done so, drag each of those items onto the form.

















The default app gives a good example, it uses the ScanCompleteEvent; which send in a string value representation of the barcode and places it text into a textbox for the user to see.

Step 4: Deploying

When deploying, remember to set the device to PtxPxa27c: ARMV4I_Release

P.S.
The size of the form shouldn't be bigger than 245 x 300
