I have a problem with a memory leak. I have this code in a button_click : Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim ms As New IO.MemoryStream Dim bm As New Bitmap("\Application Data\imgs\IMG22.jpg") bm.Save(ms, Drawing.Imaging.ImageFormat.Jpeg) End Sub This code works just fine when I'm running the .exe at my laptop (I mean under windows7/32bits with the full .net framework) but when I run the app in a device with WindowsMobile 6.1 the app throws this exception: SmartDeviceProject22.exe OutOfMemoryException at Microsoft.AGL

I have a .Net Compact app running on Windows Mobile, and I want to be able to connect to a webservice running on the 'host' machine (i.e. the desktop the PDA is plugged into) when connected via ActiveSync, but I don't know the ip address of the host. How can I find the ip of the desktop PC progromatically on the PDA? I've found a KB article How To Retrieve the IP Address of the Remote PPP Peer , which uses the host "PPP_Peer". So I tried: Dns.GetHostEntry("PPP_Peer").AddressList[0] And that does give me what I'm looking for (169.254.2.2 on the PC I'm using at the moment). Getting the address

Is it possible to know who got the focus in a lost focus event? Compact Framework does not have an ActiveControl , so I don't know how to tell who got the focus. Vaccano This is the solution that ended up working: public System.Windows.Forms.Control FindFocusedControl() { return FindFocusedControl(this); } public static System.Windows.Forms.Control FindFocusedControl(System.Windows.Forms.Control container) { foreach (System.Windows.Forms.Control childControl in container.Controls) { if (childControl.Focused) { return childControl; } } foreach (System.Windows.Forms.Control childControl in

How - or what's the best way - to retrieve the device's current battery level in .NET CF 3.5 on Windows Mobile 5 and 6? Noldorin I think you want to use the Microsoft.WindowsMobile.Status namepsace (specifically the SystemState class. using Microsoft.WindowsMobile.Status; ... BatteryLevel batteryLevel = SystemState.PowerBatteryStrength; BatteryState batteryState = SystemState.PowerBatteryState; See this post for the full code sample. You probably want the State Notification Broker class that Noldorin is recommending. I don't think it gives you very fine grain information. You get information

I use the p/invoke method to play wav sounds. There are ways of calling windows media player to play an mp3 sound, but its slow & cumbersome. Is there an easy way to play a short mp3 file? This is primarily for application prompting and audible cues when you are not looking at the screen and not music. Thanks! CF Framework 3.5 now includes support for playing .WAV files: Namespace System.Media.SoundPlayer Short WAV files for cues and sound-effects might even play faster than MP3s since they're "ready-to-play"... If you are looking for a way to play mp3s: public class Sound { [DllImport(

I really want to upgrade to Visual Studio 2010. But since I do a lot of development for the Pocket PC version of Windows Mobile I cannot. (I develop for a Symbol device that does not support Windows Phone 7, so that is not a option.) Does any one know any kind of time frame of when Microsoft plans to add support for Smart Device Projects into Visual Studio 2010? Update: Since this is looking less and less likely without intervention from the users, Please go here and vote for this feature. Microsoft's current public statement says that, apart from Windows Phone 7 development, there will not be

See subject, note that this question only applies to the .NET compact framework. This happens on the emulators that ship with Windows Mobile 6 Professional SDK as well as on my English HTC Touch Pro (all .NET CF 3.5). iso-8859-1 stands for Western European (ISO), which is probably the most important encoding besides us-ascii (at least when one goes by the number of usenet posts). I'm having a hard time to understand why this encoding is not supported, while the following ones are supported (again on both the emulators & my HTC): iso-8859-2 (Central European (ISO)) iso-8859-3 (Latin 3 (ISO))
