    - Full duplex audio with the Waveform Audio Interface Hello, I am developping a VoIP application between Ipaq. I use the Waveform Audio Interface to capture and play audio. (See the MSDN example, it is the best on audio capture and playback on .NET http://msdn.microsoft.com/mobility/default.aspx?pull=/library/en-us/dnnetcomp/html/waveinout.asp You can download the sample code, it is much easier to modify than OpenNETCF). I would like to make my application full duplex,(capture,stream and play the sound simultaneously on the 2 ipaqs)). Problem: I get an error when I try to record sound while playing sound. Does the problem come from my ipaq ? (I use Ipaq rx3715). Or is it a limitation of the Waveform Audio Interface ? Thank you, Lionel Reyero Tag: Supporting an application in production... Tag: 49918

    - MSDN Form Load Performance Enhancement... I read this article on msdn that sounds great and makes sense about how the designer by default does things a certain way for adding controls to the form...And that there is a better way to do me.control.controls.add(me.othercontrol) you can do me.othercontrol.parent = me.control However, everytime that I go back to the designer it changes the code that I had changed in InitializeComponent. Is there a way to make this not happen? Thanks http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/dhtml_node_entry.asp Tag: Supporting an application in production... Tag: 49915

    - SendMessage not working? Hi, Starting with a clean smartphone project, I have the main form with a textbox in it called textBox1. I'm trying to add text to it using SendMessage (to avoid that annoying flicker). Here are the pinvokes... const uint EM_REPLACESEL = 0xc2; [DllImport("coredll")] extern static IntPtr GetCapture(); [DllImport("coredll")] extern static int SendMessage(IntPtr hWnd, uint Msg, bool WParam, string LParam); Here's the code that should update the textbox: textBox1.Capture = true; IntPtr hWnd = GetCapture(); textBox1.Capture = false; SendMessage(hWnd, EM_REPLACESEL, false, "hello"); I successfully get a handle on the text box, but the word "hello" doesn't appear in the text box. Any ideas what I'm doing wrong here? TIA Mark Tag: Supporting an application in production... Tag: 49913

(seems a bit of a pain) Thanks for the help. Rob Tag: Supporting an application in production... Tag: 49911

    - Error: Cannot establish a connection. To anyone having trouble trying to deploy their app to the pocket pc device. We kept getting the "Error: Cannot establish a connection. Be sure the device is physically connected to the development computer." We worked with someone from Microsoft and I thought I'd post the steps so someone else might benefit. STEP 1 Run Repair on Visual Studio .Net. Put your disk for Visual Studio .Net Enterprise in the drive. Go to Add/Remove Programs, select Microsoft Visual Studio .Net Enterprise, Pick Option 2 Visual Studio.Net Repair. It will run the repair processes and should take about 2 hours. STEP 2 Download the PocketPC 2003 SDK from Microsoft's website: Microsoft Pocket PC 2003 SDK.msi. It should be around 84MB. It takes about 5 minutes to install. STEP 3 Copy the DelCryptoKey for your type of device to your PDA. It should be in this directory: C:\Program Files\Microsoft Visual Studio .NET 2003\CompactFrameworkSDK\WinCE Utilities\DelCryptoKey After copying it to your PDA, run it. STEP 4 On your laptop or desktop, run the DelDesktopCryptKey. C:\Program Files\Microsoft Visual Studio .NET 2003\CompactFrameworkSDK\WinCE Utilities\DelDesktopCryptKey Now launch Visual Studio and see if this resolves your connection issue. It worked for 3 of our desktops that were having trouble after we had upgraded our systems to Windows XP. We had done PocketPC development on these same machines with Windows 2000 but when we upgraded we started getting the error. Hope this helps! Tag: Supporting an application in production...

    - Environment variable for Deployment Device? Hi, I'm using a eVC++ dll in my .NETCF project. I would like to automate the build so that the correct dll is copied to the output folder depending on what deployment device is currently being build. For example, if the deployment device is .NET Emulator, then the Win32 emulator dll would be copied, otherwise if my ARM device is being build, the ARM dll would be copied. I'm assuming there is no such variable. Is there anyway I could use a dumpbin or something similar to figure out the cpu type of the binary? I could then parse the output. Thanks.

    - DLL Problems w/ Compact Framework I have some C# code which I would like to be able to call from a Visual Basic appication. Both the C# and VB applications are written for the .NET Compact Framework. I compiled the C# stuff as a DLL by creating a new C# project as a "Class Library", and then copied the code over. Everything compiles just fine. However, when I include the DLL in my VB application, I get the error: Error: The dependency 'mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=969db8053d3322ac' in project 'VBReceiveSMS' cannot be copied to the run directory because it would conflict with dependency 'mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. I read in another thread that this means that I'm using code for both the regular .NET Framework and the .NET Compact Framework (see http://www.dotnetmonster.com/Uwe/Forum.aspx/dotnet-compact- framework/10974/mscorlib-Error). Is this true? Is there any way in which I can compile my C# stuff as a DLL and run in VB using the .NET CF?

    - Importing XML - Need some help please I am having a problem pulling in XML data into a PPC Compact .NET app and saving it to a SQL CE .SDF file. I get an error message that is simply the name of the first column. I have checked everything I can think of to no avail. My steps in the code: - Create a connection to the SQL CE .SDF file - Create a command for table direct access to the main table - Create a data adapter from the command - Create a data set - Read in the XML schema from the XML schema file I created on the desktop - Create a command for an insert and store it to the data adapter insert command - Add all the necessary parameters using the correct data types - Do a DataAdapter.Update(DataSet, "Table") On this command is where I get my exception.

    - Databiinding to Combobox I am using Databinding to fill a Combobox Display and Value members with info from a table. My problem (below code) happens twice. I call the following code once when the form loads. Form description: Combobox loads with form (and after SQLCE sync) from .sdf file Treeview populates based on item selected from combobox. more happens after this, but I'm confident I have that handled. ------------ Code ------------------- cmbLot.Items.Clear(); string cmbstr = "SELECT ColOne + ' - ' + ColTwo as Display, PK FROM TableOne ORDER BY Display"; try { SqlCeConnection connCE = new SqlCeConnection("Data Source=" + strCEDatafile); SqlCeDataAdapter daNames = new SqlCeDataAdapter(cmbstr, connCE); try { DataSet dsConnect = new DataSet(); DataTable Combo = new DataTable("Combo"); connCE.Open(); dsConnect.Tables.Add(Combo); daNames .Fill(dsConnect, "Combo"); cmbLot.DataBindings.Add("SelectedItem", Combo, "Display"); cmbLot.DataBindings.Add("SelectedValue", Combo, "PK"); cmbLot.DataSource = Combo; cmbLot.DisplayMember = "LotNum"; cmbLot.ValueMember = "PK"; connCE.Close(); } catch(SqlCeException sqlex) { string sqlCEerror = sqlex.Message.ToString(); } } catch (Exception ex) { clsErrors.WriteEx(ex); MessageBox.Show("Error reading data file.\nContact Helpdesk", "Combobox Error"); } ------------ Code ------------------- Then I am waiting for the user to select from the items that populate this Combobox. The problem is that while loading this the OnSelectedIndexChanged event fires 4 times (index of 0). (I'm loading 23 items in my test environment). Then..... once I select an item, it fires multiple times again. This causes problems with the code I want to run when a new item is selected. It runs once ok, but it runs 4 times. Its almost like it is reloading the databinding every time I fire any event on the form. I've traced the event, the "index" change is first, the selected index, then 0, then the selected index, then 0 again. I have used dynamic fills on comboboxes without problems before, but not databinding. TIA for any help Z Tag: Supporting an application in production... Tag: 49865

    - Network Logon I am converting an application from Windows CE 3.0 written in EVC++3.0 to a Windows Mobile 2003 device using C# and the compact framework. In the application I copy files from a network share onto the mobile device. On the 3.0 device I was able to enter the logon credentials from a control panel applet prior to giving the device to the users, thus eliminating the network logon prompt during program execution. On the WM2003 device there does not appear to be an equivalent control panel applet to enter the logon credentials so my users are forced to enter a logon, password and domain the first time the program tries to copy files. Do you know a way of pre-configuring the network credentials and/or where they are stored on the system once they are entered on the WM2003 device? They do not appear to be in the registry.

    - Effect of changing computer name on Connection when debugging app I developled a PocketPc App last year and another group in our company wanted to use it. I was charged with the task of creating a slimmed down image of our solution so they would have a head start. When I went to debug the app I started getting connection errors and I started trying to find things in various forums to give me an idea of what to do to fix it. One thing led me to the Windows/NETCFKeys on my mobile device. I realized that there is are 2 files: Administrator.FSDSBrooksR and a BrooksR.FSBBrooksR. We recently changed our computer names when we upgraded to XP and my computer name was changed from FSBBrooksR to FSDSBrooksR. Should I delete the reference to FSBBrooksR and will Visual Studio create a new one when I try to debug it? Is this causing or likely causing my connection problem?

The issue is that I've got this toolbar which call "this.Close()" on my Form, by some obscure reasons I need to press the toolbar TWICE before the form actually CLOSES... I have stepped through the code and verified that the code is actually CALLED but still the Form isn't being closed... The form is being showed with ShowDialog() and it doesn't contain alot of fancy stuff. I've got one custom DataGrid control in it, but that DataGrid works perfect in other forms. I'm using the OpenNETCF/SDF in my app and I've optimized the InitializeControls with the "rules" to make it faster. (setting Parent property instead of adding the controls, loading controls top-down style etc...) Form is localized for two languages but I've handremoved everything in both resx files and InitializeControls which don't have anything thing to do with "text" properties (optimization) It seems to me as if the "Close" method on the form is somehow "broken"...?? Appreciate any suggestions... I can submit code, but it's gonna be LONG... (650 lines...) Also I've got lots of forms in my app, many which are way more "advanced" then this one, many ofo the also "optimized" but they all seem to function perfect except this one though...

    - Binary Serialization of decimal types I'm working on an application where we need to persist decimal values on a PocketPC device, but the Compact Framework doesn't support decimal types in the BinaryWriter/ BinaryReader classes, or even in the BitConverter class. Is there some nice, happy way to convert a decimal into it's byte array equivalent through the framework? At the moment, I'm accomplishing the task by using some unsafe code that looks like this: public byte[] Serialize( decimal d ) { byte[] data = new byte[16]; // decimals being 16 bytes fixed( byte *ptr = data ) { *(decimal *)ptr = d; } return data; } Deserialization works almost exactly the same way. Is there a better way to do this conversion, and are there any problems with this particular method of doing the conversion?

This client works fine on non-CF with the same web service. I did not use sessions, just store the object in the Application, and retrieve when needed. Appreciate your help!

The application that I'm working on is not targeted to go to production
until December of this year, but i was talking with some colleagues and
wondering if there is a problem in the field what are some of the best ways
to support the device...

I've thought about getting a copy of their sqlce DB and running my
application hitting their data, or writing some log files/log tables when
things go wrong...

What are you some of you guys solution for supporting your application in
production when something goes wrong?

Usually I have a log file that traps errors and capture any other information I may find usefull while the applicaiton is out in the field. Check out this article http://msdn.microsoft.com/smartclient/default.aspx?pull=/library/en-us/dnnetcomp/html/instnetcfapp.asp for more information

Mark,

The article seems to be talking about getting the files back to the
desktop using ActiveSynch with the device in a cradle?

What about the devices that are out in the field with no cradle?

Thanks
