No icon on my shortcut

themonz31 — Fri, 10 May 2013 06:40:28 GMT

Hi guys,

I've created an application with a Setup.

In the setup, I have a %CE3% section to create a shortcut to my application.

Installation works, the shortcut is well created on the desktop and works fine.

the issue is that I don't have any icon (default one only) for my shortcut.

My application (a winCE one) is build with the shortcut (in the release directory, I can see my application with the right icon), but neither

the shortcut nor the "programs\Myapplication.exe" have the icon associated with visual studio.

What am I missing ?

thanks

Application is killed on onTriggerEvent(TriggerEvent te)

antonmennel — Wed, 01 May 2013 18:46:59 GMT

Hello

I have developed a Java application that uses the com.teklogix.trigger.TriggerControl class to receive events when the middle scan key is pushed. Creating the TriggerControl object, registering the consumer, mapping the key and registering for events works fine. No Exceptions or Errors thrown here. However, after the last step - registering for events - automatically (without pressing any key) an onTriggerEvent is thrown. This event is of course caught by our class. After that, the application is closed/ended without any message. This is somehow confusing, since we are currently not doing anything in the onTriggerEvent(TriggerEvent te) method.

Here is my code:

-----------------------------------------------------------------------------------
private mcTrigger()

{
private String CLAZZ = "mcTrigger";
boolean ok = true;

// create control
try
{
triggerControl = new TriggerControl();
}
catch(OutOfMemoryError oome)
{
// stop working
ok = false;
}
catch(Exception e)
{
// stop working
ok = false;
}

// deregister consumer (just to make sure)
if (ok)
{
try
{
triggerControl.deregisterConsumer(CLAZZ);
}
catch(Exception e)
{
// continue working
}
}

// register consumer
if (ok)
{
try
{
triggerControl.registerConsumer(CLAZZ);
}
catch(Exception e)
{
// stop working
ok = false;
}
}

int scanKey = Keyboard.translateToTriggerID(Keyboard.KEY_SCAN);

// Remove all consumers currently associated with the Scan key
if (ok)
{
try
{
triggerControl.removeAllMappings(scanKey);
}
catch(Exception e)
{
// continue working
}
}

// add key mapping
if (ok)
{
try
{
triggerControl.addMapping(scanKey, CLAZZ, TriggerControl.FLAGS_OVERRIDE | TriggerControl.FLAGS_TEMPORARY | TriggerControl.FLAGS_WANTS_TRIGGER_EVENTS);
}
catch (TriggerException tex)
{
if (tex.getTriggerError() != TriggerError.MAPPING_EXISTS)
{
// stop working
ok = false;
}
}
catch(Exception e)
{
// stop working
ok = false;
}
}

// register for events
if (ok)
{
try
{
triggerControl.registerForEvents(CLAZZ, this);
}
catch(OutOfMemoryError oome)
{
}
catch(Exception e)
{
}
}
}

// ------------------------------
// Interface TriggerEventListener
// ------------------------------
/**
* @see TriggerEventListener#onTriggerEvent(TriggerEvent)
*/
public void onTriggerEvent(TriggerEvent te)
{
System.out.println("mcTrigger triggerEvent - got event: ");
System.out.println("- event: " + te);
System.out.println("- SourceId: " + te.getSourceId());
System.out.println("- Source: " + te.getSource());
}

-----------------------------------------------------------------------------------

When running the application, the end of the output log of our application shows the following:

mcTrigger triggerEvent - got event:
- event: com.teklogix.trigger.TriggerEvent[source=mcTrigger]
- SourceId: 0
- Source: mcTrigger

Then it ends.

I tried several things:

- Do not register for events --> Application keeps running, onTriggerEvent() is not called, but pressing the middle scan button does not do anything
- Do not add mappings --> Application keeps running, onTriggerEvent() is not called, but pressing the middle scan button does not do anything
- Change Flags when mapping keys --> No change, application is killed
- Map another key --> No change, application is killed, SourceID in onTriggerEvent is always 0, no matter what key is mapped

The device I'm using is a Psion Workbout Pro 3:

Any help is much appreciated. Thanks!

MDSDK 6.0 CreateFile(SCS0:) exception when constructing ScannerServicesDriver

coffeenkfc — Wed, 08 May 2013 21:32:03 GMT

Hi, first time developing PSION, this is on a work about pro 3 windows mobile using VS2008, C#/.NET and MDSDK 6.0

On this line of code:

this.ScannerServicesDriver = new ScannerServicesDriver();

I get the following exception:

Win32Exception

CreateFile(SCS0:) at PsionTeklogix.Win32.ThrowException(String message) at PsionTeklogix.Barcode.ScannerServices.ScannerServicesDriver.GetHandle() at

PsionTeklogix.Barcode.ScannerServices.ScannerServicesDriver..ctor() at

...

I get the same problem with this sample app http://community.psion.com/downloads/developer_sdkhdk/m/sample__demo_code/30319.aspx

I thought it must be because I didn't copy a DLL over but I copied every DLL I can think of and still have the issue. Here's a list of DLLs now sitting beside the executable on the handheld:

mdsdkcore.dll
Microsoft.WindowsCE.Forms.dll
PsionSensorsC.dll
PsionSensorsC.lib
PsionSensorsNet.dll
PsionTeklogixNet.dll
PtxSdkCpp2008.dll
PtxSdkWlanExCommon.dll
PtxSdkWlanExCpp2008.dll
PtxSdkWlanExNet.dll
PtxSdkWwanCommon.dll
PtxSdkWwanCpp2008.dll
PtxSdkWwanNet.dll

In my project the only reference I have is to PsionTeklogixNet

I would so much appreciate someone telling me what I'm doing wrong, the client wanted this app yesterday (as they always do LOL).

Thank you kindly,

Ben

Code Sample for PtxRemoteSock.dll on NB Terminal

mjbrandys — Tue, 07 May 2013 20:37:12 GMT

Is there any sample code available that shows how to use the PtxRemoteSock.dll to open a TCP connection to a remote host from a Narrow band terminal?

Ideally, I would like to modify an existing .NET application that makes a simple webservice call. The code currently runs on a 7535G1 / wifi terminal, and I would like to port to a NB terminal.

High Quality Images

jpassos — Wed, 13 Apr 2011 09:01:47 GMT

Hi,

Is it possible ,using Ikon, to obtain images with 1600x1200 resolution ?

If so, is there any minimum requirements regarding SDK used, Imager version, etc.

Is there also any kind of demo code showing who to do it ?

I use the code from the SDKsamples but the maximum i can get is 640x480.

Thank you for your help.

App hangs when trying to close GPS. EP10

Alutel — Tue, 30 Apr 2013 14:24:58 GMT

Hello,

I'm using the GPSSample from Mirosoft to use the GPS data in my app. I am working with EP devices.

My problem is that sometimes when I try to close my app it hangs when it tries to close the GPS. This is the function which uses the sample:

/// <summary>
/// Closes the gps device.
/// </summary>
public void Close()
{
if (gpsHandle != IntPtr.Zero)
{
GPSCloseDevice(gpsHandle);
gpsHandle = IntPtr.Zero;
}

// Set our native stop event so we can exit our event thread.
if (stopHandle != IntPtr.Zero)
{
EventModify(stopHandle, eventSet);
}

// block until our event thread is finished before
// we close our native event handles
lock (this)
{
if (newLocationHandle != IntPtr.Zero)
{
CloseHandle(newLocationHandle);
newLocationHandle = IntPtr.Zero;
}

if (deviceStateChangedHandle != IntPtr.Zero)
{
CloseHandle(deviceStateChangedHandle);
deviceStateChangedHandle = IntPtr.Zero;
}

if (stopHandle != IntPtr.Zero)
{
CloseHandle(stopHandle);
stopHandle = IntPtr.Zero;
}
}
}

There's some other way to close the GPS and exit the app without hanging it?

Managing WiFi and 3G connection on WAPG3

Mazhar Iqbal — Wed, 10 Apr 2013 14:16:14 GMT

Hi Psion Developers,

One of our Software partner is looking to use the adhoc wifi network to communicate between the WAPG3 and Pin Entry Device while also communicating from the WAPG3 to external web services via 3G.

They need to understand whether they can/should use both at the same time and/or how easily/quickly they can switch between 3G & GPRS. They like to know if there are any known show-stoppers in this area which can interfere with the connection. Can both connections be used at same time without any affect on each other?.Any past experiences or the advice would be very helpful.

Please see the exact Scenario below.

IESimple and Function Keys (F1, F2, F3, F4, F5)

xioma — Mon, 29 Apr 2013 18:57:11 GMT

Hi Guys,

We developed several applications with SAP ITS Mobile (web applications). In IE these applications work ok (the handheld have Windows Mobile 6); but IE works really slow, so we installed IESimple but we have a problem: in the web applications we work with event on key down from java script to manage the function keys (F1, F2, F3, F4, etc). In IE the ascii code returned in event are F1: 101 F2: 102 F3:103 F4: 104; but IESimple returns F1: 9 and F2, F3, F4 "undefined", we need to work with function keys....do you know why this happens?

thanks in advance!!

FileStream File Saved with UTC Time

psionhack — Sun, 28 Apr 2013 20:05:24 GMT

The time stamp on a file created and saved in a WAP3 Windows Mobile 6 .NET application appears as UTC, when viewed or copied Windows Mobile Device Center.

How do we get the file time to appear as the local time?

Both the PC and WAP3 are configured for the same time zone.

Thanks in advance.

Getting images from the imager on the EP10 in C++

david@imense.com — Fri, 26 Apr 2013 15:26:27 GMT

I know this is a big ask but does anyone have a C++ code snipped that would

1) initialise the greyscale imager to take full resolution greyscale photo type images

2) trigger the imager

3) pass the pixel data into a C++ routine.

The example code dumps a veery subsampled image straight to disk.

Time Synchronisation on EP10 and IKON

Mazhar Iqbal — Thu, 18 Apr 2013 12:15:02 GMT

Hi,

One of our customer has been using Ikon's and EP10's. They are using some sort of iClient (Java client) and software provider has stated that Psion devices (EP10 and Ikon's) returning the wrong time to Java client after this BST time change. It's showing 1 Hrs behind the correct time. The time on the IKon's and EP10 always shows the correct time, and they also have time Synchronisation set up within SOTI server.

The time that is shown incorrectly is within iClient. Could some give any suggestions. I am suspecting the wrong function being used to get the time from our devices. I am sure one our top developer would come with the answer and solution

Needed RAS server on WEH6.5 (EP-10)

Pawel L - AXED — Wed, 17 Apr 2013 10:08:17 GMT

Hi,

We need to integrate a reader with EP-10 (or MC67), so we need an information if that's possible to run RAS server on WEH6.5.
Following this entry on IW: http://community.psion.com/knowledge/w/knowledgebase/1302.ras-remote-access-service-8000271.aspx I sadly suppose, that there's no RAS server on WEH6.5, but only outgoing connections using connection manager. That's not 100% clear for me, so my question is:

Is running incoming connection on WEH6.5 possible? If so - how?

database fields with french accents

Bill — Mon, 15 Apr 2013 16:55:09 GMT

Hi,

I am using System.Data.SqlServerCe in my applocation for the psion wap3 windows CE and I am having a strange problem.

I have a simple table with two nvarchar fields and in one of them I want to put utf8 strings ( ie ones that can have french accents )

I am loading data into them with INSERT Destinations(id,description) VALUES (...

But records with french accents do not go in and the table seems to become corrupt somehow.

I don't know how to get around that. Any suggestions would be ap[appreciated.

Thanks, Bill

Any VB.NET sample code to read barcodes and take photographs from multiple forms?

James Bull — Mon, 07 Feb 2011 10:13:32 GMT

Hi All -

I'd like to know if we have any VB.NET sample code to read barcodes in 3 or 4 different forms / pages, and take a photo on each one using the camera.

We have sample code in C# but do we have VB.NET code?

I appreciate you can get converters to convert c# to VB but it would be useful to have a set VB sample code base as well as the C#.

Regards,

James

Change the Current SSID Programatically

psionhack — Thu, 04 Apr 2013 21:50:01 GMT

Is there a known method/technique for changing the current SSID in a WAP3 with a Summit WLAN adapter?

The idea is to be able to switch over to another backup network if required without user intervention.

Thanks in advance.

Use the DS3578 on Windows CE

themonz31 — Fri, 05 Apr 2013 13:19:07 GMT

My question will be quite simple...

I have a DS3578 (Hand scan) that I can use connected to my Laptop (running Windows XP / Seven). I have installed driver from motorola

to use a com object Interop.CoreScanner to handle the scanner. Thus, I am able to switch the scanner to "SNAPI Imager" mode and get a image

when asked to the scanner.

Now, I've got to make this work on a 8530 terminal. This terminal is running under Windows CE and this is my point... Is there any way to

make it works on this platform ? I've searched for Windows CE driver but nothing is available. I just want to "plug" my scanner to a usb port of

the 8530 (to plug the docking station of the DS3578 to be more precise) and be able to get "image" capture from the scanner (as I do under XP/Seven/8).

I really need clues because I'm stucked and don't know what to try...

thanks for any ideas, even silly one... (except the fact to give up and choose a product under XP)

Nicolas, Toulouse

POLL: Open TekTerm and SSL

We're doing research on enhancements for Open TekTerm. One of the features is SSL (Secure Socket Layer): http://en.wikipedia.org/wiki/Secure_Sockets_Layer

With the Secure Sockets Layer (SSL) protocol, it is possible to establish a secure connection between the AS/400 and a Telnet client.

Please vote 'Yes' if there is demand for SSL when using TekTerm for direct connections or without the Communication Server:

8525 G2 VMT Serial Port Data

Vinay.Singh — Mon, 01 Apr 2013 07:04:08 GMT

Hi,

We have an application on 8525 G2 VMT. The app has developed the serial port interface with the VMT. The app expects the data on the serial port and is capable of fetching data. The issue is when we configure the VMT (Serial port) it consider this as a Scanner and puts the data wherever the cursor is. We need to configure the device in such a way that the data does not goes into text fileds, if we can disable the option of populating the text fields with the serial port data, we can process the data as and when required as per the application requires.

Thanks and Regards,
