Hello,
I have a very simple test DB application (VS2008 SP1, CF 3.5 SP1, SQLCE 3.5SP1, C#)that displays a datagrid and fills it with data on load, tableAdapter.Fill, and a button that executes a second time the same command tablaAdapter.Fill.
Deployed on CE 5.0.
1) on WM5.0 emulator works when run from vs2008, debugging (by the way, anyone has an idea on where to find a CE5.0 emulator ready to use under VS2008?)
2) on CE5.0 device works when run directly from the device
3) on CE5.0 device when run from vs2008, with debugging, displays the data, but when I click the button it gives a SqlCeException error on:

<br />
        [global::System.Diagnostics.DebuggerNonUserCodeAttribute()]<br />
        [global::System.ComponentModel.DataObjectMethodAttribute(global::System.ComponentModel.DataObjectMethodType.Fill, true)]<br />
        public virtual int Fill(AppDatabase1DataSet.testDataTable dataTable) {<br />
            this.Adapter.SelectCommand = this.CommandCollection[0];<br />
            if ((this.ClearBeforeFill == true)) {<br />
                dataTable.Clear();<br />
            }<br />
            int returnValue = this.Adapter.Fill(dataTable); // here the error<br />
            return returnValue;<br />
        }

Any suggestion?

Thanks,
Mattia

Hi,
Your query is not clear. but i think you want to start your camera. if yes then try this code.

Dim ccd As New Microsoft.WindowsMobile.Forms.CameraCaptureDialog
        ccd.Resolution = New Size(100, 200)
        ccd.Mode = Microsoft.WindowsMobile.Forms.CameraCaptureMode.Still
       ccd.Mode = CameraCaptureMode.Still
        ccd.Owner = Me
        ccd.Title = "Take a Picture"

       If ccd.ShowDialog() = Windows.Forms.DialogResult.OK Then
            If ccd.FileName <> String.Empty Then
                PictureBox1.Image = New Bitmap(ccd.FileName)
                ccd.Dispose()
            End If
        End If

May be it helps you.
Thanks

on which operating system you are compiling this project ?
You can compile in VS2008 and save the exe in your mobile divice and can run from there put one botton on your Form which will active your camera on mobile device and later can see that on My documents on mobile devie . Hope it helps

cc.DefaultFileName = "Picture .jpg";
cc.InitialDirectory = "\\";

Hi
Windows Mobile 5.0 Pocket PC Emulator does not provide the camera facility on the emulator. For debug your project on the Emulator you can use the Windows Mobile 6.0 Pocket PC Emulator.
May it solves your problem.

Thanks

I am developing a Windows Mobile 6.0 application. I need to make the application multilingual.. Is there any built in options available to change language as per our selection..

The language used on the device is selected through the regional settings. After that setting is changed the device must be reset for the change to take affect. Only then will you be able to see the change in the thread culture and UI culture.

I don't know on Windows Mobile if it works but in Windows Forms I do so:

System.Threading.Thread.CurrentThread.CurrentUICulture = New Globalization.CultureInfo(LangCode)

where LangCode is the language code you want to change in your application. (for example it-IT for Italian or en-US for english USA)
Hope this helps Smile | :)

Playing AVI on Windows Mobile using C#

Hi, everyone!

I'm writing a video player for Win Mobile...

Does anybody know which library should I use. Is there any library for unmanaged AVI handling using P/Invoke or high-level one with programmer-friendly interface. Some other ways, maybe (C# compatible only).

Looking forward to your answers...

I don't know of anything that was designed for managed developers, but for native developers there's DirectShow and of course embedding the Windows Media Player control.

Is there any possibility to use DirectShow in my c# code and if there is, can you explain how to do it?

There's no intrinsic support. You are going to have to make use of P/Invoke.
