Migrating to VisualStudio 2008 / Version 2.3 of SmartDeviceFramework

that.trevor — Mon, 07 Mar 2011 19:08:18 GMT

I recently upgraded my application from Visual Studio 2003 to 2008 and I started to get a bunch of warning messages complaining that various control properties were not supported. e.g.: The type 'Microsoft.CompactFramework.Design.UnsafeControl' has no property named 'TextAlign'. I tried upgrading my libraries to the newest smart device framework (2.3) and I started to get other problems: Type 'OpenNETCF.Windows.Forms.ButtonEx' is not defined. I tried changing the types of the controls to what appears to be the new equivalent (e.g.: rename ButtonEx to Button2) but then I go back to the original problem (missing properties). Two questions: * Why does the newer version of Visual Studio have trouble with these properties * Do you have any tools for migrating to new versions of the framework and / or visual studio Thanks, ~Trevor

Set Device Date Time from Desktop Application

jmro20 — Tue, 04 Jan 2011 22:47:44 GMT

Hi, I've been trying hard to set the device date and time information from a desktop application. I am new to mobile development and I really don't have an idea of how to accomplish this. I have tried using rapi.Invoke coredll.dll SetSystemTime (using OpenNETCF.Desktop.Communication) but without any success. Is there a way to do this? I did a lot of google search but didn't find anything. Please help me I am totally lost!!. Thanks

WIFI connection - Signalstrength

jkorsten — Wed, 08 Sep 2010 12:07:39 GMT

Hello everybody,

I have a problem. I'm using OpenNETCF.Net.NetworkInformation.AccessPoint to get the signalstrength of the Wifi connection.

This is going fine. BUT, when I get closer to the accespoint the signal gets stronger and I can get a dBm signal from -90 till -70 when the signal gets stronger it disappears. The accespoint can't be found.

Some more information. The accespoint i'm looking for is from a hidden network with a WEP key. I can detect the network but when the signal gets stronger it dissapears (but the WM-device stays connected).
The neighbours have a WPA2 key and this network doesn't give any troubles even with a signalstrength of -60.

What can be the problem here?

Kind regards,

JKorsten

ps: the code I use is:

try
{
Boolean bParlWifi = false;
// Get all the WZC Network Interfaces
foreach (OpenNETCF.Net.NetworkInformation.INetworkInterface currentNetworkInterface in
               OpenNETCF.Net.NetworkInformation.WirelessZeroConfigNetworkInterface.GetAllNetworkInterfaces())
{
    // Make sure we are dealing with a WZC Network Interface
    if (currentNetworkInterface is OpenNETCF.Net.NetworkInformation.WirelessZeroConfigNetworkInterface)
    {
      OpenNETCF.Net.NetworkInformation.WirelessZeroConfigNetworkInterface wzc =
        (OpenNETCF.Net.NetworkInformation.WirelessZeroConfigNetworkInterface)currentNetworkInterface;
      // Get all the Nearby Access Points that the WZC Network Interface can see
      listBox1.Items.Clear();
      foreach (OpenNETCF.Net.NetworkInformation.AccessPoint currentAccessPoint in wzc.NearbyAccessPoints)
      {
        // Output the name and the signal stregth of this access point
        this.listBox1.Items.Add(currentAccessPoint.Name + " : " + currentAccessPoint.SignalStrength.Decibels.ToString() + " : "
                                           + currentAccessPoint.PhysicalAddress.ToString());
      }
    }
}
}
catch (Exception ex)
{
MessageBox.Show("Problem : " + ex.Message);
}

problems with getting the NearbyAccessPoints

banti — Fri, 23 Jul 2010 12:14:28 GMT

Hello!
I have 2 smart device phones:
1. I-mate JasJar with windows mobile 5.0
2.HTC Touch 2 with windows mobile 6.5 (i just bought it)
I try to develope an application that lists the nearby acess points, like this( http://msdn.microsoft.com/en-us/library/aa446491.aspx) On the 1-st device it works fine,

but on the 2-nd device there arent any APs in the nearbyAccessPoint list. (same developer environment)
This is the code if it helps:

if (selectedAdapter.IsWirelessZeroConfigCompatible && selectedAdapter.IsWireless) // these bools are both true
{
AccessPointCollection acc = selectedAdapter.NearbyAccessPoints;
foreach (AccessPoint ap in acc)
{
//code
}
}
On the other hand i can read the signal strength and ssid of the AP wich is connected to my device.
Any idea? What could be the problem?
Thanks for your help.

IOControl Call Failed When Changing IP Address

Timo2505 — Tue, 06 Jul 2010 06:17:12 GMT

Chears,

Please advice me for above problem.

I'm using VS-2008, OpenNetCF 2.3.0.39 and Windows CE 6.0.

The sympthon is, when I try to change the IP address and save it (see NICVeiwer sample program from OpenNetCF), then my WinCE 6.0 device will display above error message.

The idea is, I want to change my WinCE6.0 device programmaticaly without restarting the device.

If somebody have facing the similar problem, and know how to solve the above problem, please share your valuable experience with me.

Thank you in advance for your attention.

Signal Strength in Decibels only shows increments of 10

Fred Kendall — Sat, 27 Mar 2010 19:28:35 GMT

I need to get the signal strengh in Decibels with full set of integer values from 0 thru 100. Currently, I'm only getting values of 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. How do I get the actual values from 1 thru 100 and not incremented by 10's?

Replacing ONCF's Serial with Microsoft's SerialPort

Robsta — Tue, 28 Jul 2009 14:34:21 GMT

Before I start, I'll let you know a little background about this question. Basically, we are (finally) making the leap from NetCF 1.0 to NetCF 3.5, with which a HELLUVA LOT of the OpenNetCF bases have been covered by Microsoft's traditional framework. On an initial upgrade and compile, the solution (6 projects) is wielding 79 errors compiling (and loads more to follow these no doubt).

So I've got work ahead of me with removing all of these errors, and thought I'd start off with our IrDA class (top of the list of errors). Existingly, under NetCF 1.0, we were using OpenNetCF.IO.Serial to fill the void, which has been depricated by System.IO.Ports.SerialPort.

What I'm attempting is to replace Serial.Input but see that the documentation on this site has (perhaps correctly) been replaced to represent the lack of this class in the latest SDF. However, the SerialPort class does not include this as an option. It also lacks the IREnable bool, but unsure of what relevance this has.

Could any of you clever minds figure out how I could read from the SerialPort buffer (over IrDA) to a byte[]?

Many thanx in advance.

SDF 2.3 & VS2008

j3d72 — Sun, 14 Jun 2009 11:43:47 GMT

Hi,

I just downloaded SDF 2.3 and ran the installer. I can't see any new components appearing. When I opened the sample app and clicked on a form I got "could not find type 'OpenNetCF.Windows.Forms.Listbox2'. Please make sure that the assembly that contains this type is referenced. ...." Any help is welcom.

Bear in mind, I'm rather new in .Net development.

Check if date falls in daylight time when daylight is disabled on device?

Pat — Thu, 26 Feb 2009 19:48:02 GMT

WinCE5 CF2 sdf 2.3.0.21 VS2008 visual basic

I've discovered that if I turn off automatic daylight saving time adjustment on the control panel that checks with Timezone.IsDaylightSavingTime and DateTime.IsDaylightSavingTime will return false regardless of whether or not the date does fall withing the daylight period.

Is there a way to check that ignores the system setting and just checked the date range?

I'm building a trend log app that will store all dates as UTC but when I display a date for a trend point I want to show the local time (with daylight offset if the user chooses to use daylight time).

This is a kiosk style device so users cannot use the control panel to turn on and off daylight time adjustments so I'm turning them off and adjusting manually if the user chooses use daylight time from the app itself. Of course, if I could figure out how to toggle auto-daylight adjusments programmatically this would be a lot easier...
