Unfortunately, this isn't the case - things like polymorphism and other properties of C++ lead to loads of "Undefined reference" errors when trying to access C functions from C++ code and vice versa.

The solution consist of special extern directives - the two sites below should keep you covered:

Good luck porting!

Fortunately for us, Microsoft’s patterns & practices group has just released a freely-downloadable ebook called “Rich Client Architecture Pocket Guide”. The 1MB PDF file looks at all things mobile – if you feel like giving it a spin, hit the URL below!

One resource I personally found extremely useful was Michael Dunn’s two-part tutorial. It starts by looking at the memory representation of “advanced” strings, and ends at string conversions – find it at CodeProject’s:
The Complete Guide to C++ Strings, Part I – Win32 Character Encodings
The Complete Guide to C++ Strings, Part II – String Wrapper Classes

Microsoft’s MSDN unfortunately is very confusing when it comes to strings. Nevertheless, the Win32’s String Chapter contains a few useful articles (hidden under UI…as if anyone would look there) – hit the URL below for the full scoop:
Unicode in the Windows API

The ideal solution would involve a single API call being called at program removal: as the program gets kicked off the handheld, a single call is called, thereby eliminating any and all notifications still lingering around. Unfortunately, this is not possible with the .NET CF – the solution is called Setup.dll and requires native code. While I am completely dumbfounded as to why native code is required, the only reason I can think off is that Microsoft wants to make sure that the dll is run even if the .NET framework is not installed.

José Gallardo Salazar has posted a lovely overview of the process to his blog – hit the link below for the full scoop while I try to figure out how it all works:

P.S. A template for a custom Setup.dll can be downloaded here.

ComboBox objects usually contain a list of different unique strings – the little routine below implements the behaviour desktop developers find in the .FindString method:

Private Function findItem(ByVal cmb As System.Windows.Forms.ComboBox, ByVal text As String)
Dim index As Integer
For index = 0 To cmb.Items.Count - 1 'bc of weird beh index = index
If cmb.Items.Item(index).ToString = text Then
findItem = index
Exit Function
End If
Next
findItem = -1
End Function


As usual: feel free to do whatever you feel like with this code!

Unfortunately, Plucker Desktop was not up to this gigantic task – after hours and hours of tweaking SunRise settings, I am proud to present the two shots below:

These images show a Treo 680 rendering the Android Documentation via Plucker! The file is 18MB large and should IMHO be placed on your memory card rather than in your phone’s RAM.

Hit this link to get the file!

P.S. Yes – this file really is a full pluck of Google Code’s /android/ folder…enjoy!

P.S.2 Use Vade Mecum to access Plucker files on your PocketPC!

Unfortunately, Sony Ericsson does not specify which programming language(s) can/must be used to create these panels – I am pretty sure that .NET CF developers will be left out due to the way-too-long startup time of the CLR interpreter (up to three seconds on my rx4240).

Amusingly, the SDK ships with a full XPERIA simulator – should anyone of you feel like taking the box for a spin: this is your opportunity…

Further information can be found at Sony Ericsson’s developer network!

He took the time to “decompile” the text and found a stunning amount of open source projects which were used in the creation of HTC’s user interface.

Share Source Code Across Platforms (Devices)
This article gives you a broad overview at what’s needed.

A single line can kill your app – this article tells you how to tell the VB compiler to make sure that no “unedible” code is compiled.

The code below restricts user input to the characters 1234567890 – no decimal points/commas can be entered:

Private Sub TxtX_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TxtX.KeyPress, TxtY.KeyPress
e.Handled = True
If Char.IsNumber(e.KeyChar.ToString) Then
e.Handled = False
End If
End Sub


Just paste it into the form’s code, and add the names of all numeric text boxen instead of TxtX and TxtY(you can have 1 to n).

Enjoy your numeric text box…
