    - Empty list of emulators in the Device Emulator Manager Hi, I have problems with Device Emulator in VS 2005 Pro on Vista business. The treeview in the Device Emulator Manager is empty except a single "other" node. When I try to connect to a device using the Connect to Device option from Tools menu I have a list of devices but I get no response. I've tried to remove the Application Data\Microsoft\Corecon\1.0 directory and to register the DeviceEmulatorbootstrap.dll but this doesn't helped. Also I've tried to repair the studio but no results again. Any suggestions what can cause this problem Tag: .NET Compact Framework PerformanceCounter Smart Device Development

    - Installation of Compact Framework 2.0 failed. Why? We're working on providing workaround for this issue, it should be available soon (that’s as precise as I could be, sorry). Meanwhile, please try the following procedure which works in most cases: 1. Remove all today plug-ins. 2. Remove everything from Startup folder (e.g. move to another folder). 3. Copy NETCF CAB on to device. 4. Restart the device. 5. Click on NETCF CAB as soon as device is up. 6. Restore you plug-ins and startup folder content.

    - Combo Box display mbr Working on my first PPC project with VS2005/WM 5/SQL mobile. Problem is that a combo box insists on displaying Value member rather than Display member. Another similar combobox works fine. I found that when the field type of the Primary key is numeric, Combox or list box is not an option in the drop down control type selection in data sources. So I have changed it temporarily to String and then Combo is an option. I recreated the Control but it still shows Value not Display member. Any ideas welcome Tag: .NET Compact Framework PerformanceCounter Smart Device Development

    - bitmap deploy on emulator alongwith exe hi all i want to make cards game for PDA,i m using images of cards, i m placing images in a folder and showing them at runtime on form. it works fine on windows application but gives "IOexception" exception on emulator i think it is not moving the images with exe that is why this exception comes,i mean did not find file on location and ioexception is raised.i m using the current path for the image like bmp = new Bitmap ( "../images/S1.png" );// new Bitmap ( "S1.png" ); also tried but failed _Image = Image .FromHbitmap(bmp.GetHbitmap()); then drawimage is called. i have also viewed on emulator where exe was present there were not images folder not single image. my question is how to deploy images alongwith exe so that it images folder is also deployed alongwith exe, or it will not deploy images and i had to give path like c:\\.images etc Thanks in advance.

    - embedding and updating content Hello, 2 questions: 1. What is the downside of embedding a web page as a gadget In my case Im trying to convert what is originally a web page into a gadget. Is there any reason why I shouldn't just embed a modified web page 2. Im trying to write a simple gadget that contains links, when clicking a link I want to change the displayed information on the gadget. Ive looked at the Quote of the Day example, but that code is a bit over my head... does anyone have an easy to comprehend example (in short I want to be able to make links that doesn't link to a new page but instead changes the information inside of the gadget) Tag: .NET Compact Framework PerformanceCounter Smart Device Development

    - Getting the handle of Textbox in .Net Compact Framework 1.0 You can restrict a box to just numeric by catching the KeyPress event of the text box and ignoring the non-numeric characters. The code would be something like (vb) Private Sub TheTextBox_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TheTextBox.KeyPress If (e.KeyChar = Convert.ToChar(Keys.Back) OrElse e.KeyChar = Convert.ToChar(Keys.Delete) OrElse IsNumeric(e.KeyChar)) Then e.Handled = False Else e.Handled = True End If End Sub -I know this should work with .net cf 2.0, not sure about 1.0 though Tag: .NET Compact Framework PerformanceCounter Smart Device Development

    - CreateWindow and WM_ACTIVATE syncronization? Hello I noticed that after calling CreateWindow a message is dispatched to WM_ACTIVATE. My question is if there is any way using the SDK to determine if this is the first time WM_ACTIVATE is being called or not. My problem is that I have data that needs to be initialized in order for WM_ACTIVATE to work properly and this is not the case when WM_ACTIVATE is triggered by CreateWindow. The solution I have today uses a boolean flag to check for first occurrence but my question is if this would be possible to solve using a SDK function. Perhaps by checking if the window has been created or not Any ideas Many thanks, Martin Malek Tag: .NET Compact Framework PerformanceCounter Smart Device Development

    - Debugging WinCE 5 apps not working I'm trying to debug a Compact Framework 2.0 app on a Windows CE 5 device from VS2005 sp1. I assumed this should just work out of the box. When I set a breakpoint in the CF app, deploy and start debug the breakpoint indicates it wont be hit. The little exclamation point icon on the breakpoint indicates 'the specified module has not been loaded'. Any idea what is causing this The app deploys and runs fine on the device but I cannot debug. I thought this was a no-brainer. Tag: .NET Compact Framework PerformanceCounter Smart Device Development

    - Web service via a proxy server I have an application written in C# using .Net CF 2.0 which consumes a web service which sits on one of my servers. My device is running WM5 and the dev env is Visual Studio 2005. In the code, I create the web service, check there's a valid internet connection like this: ... req = ((HttpWebRequest)(WebRequest.Create(" http://www.microsoft.com "))); res = ((HttpWebResponse)(req.GetResponse())); if(res.StatusCode == HttpStatusCode.OK) return true; ... and then invoke a method on the webservice. This all works fine with the device cradled until I change my network settings to go via a proxy server. The PPC seems to pick up these proxy settings after a reset and I can see the web service via IE on the device. However, when I run the code it fails as soon as I try to invoke a method on the web service. The calls to the WebRequest used to check the internet connection still succeeds, but the webservice calls fail. The exception's HResult is -2146233079 and the _message is "WebException", there is no innerexception. I've tried setting the following just before I create the webservice: System.Net.GlobalProxySelection.Select = new System.Net.WebProxy(" http://192.168.x.x:6588 "); and I also set the following when I create the webservice: cws.Proxy = new System.Net.WebProxy(" http://192.168.x.x:6588 "); both of which are using the correct IP and port number. but this has no effect. I'm assuming that if the internet connection is fine in the app then I shouldn't need to make these calls anyway. I also assume that I'd only need to set the System.Net.GlobalProxySelection.Select and all subsequence web requests would then use these setting so there'd be no need to specify the proxy when I create the web service. Does anyone know what the problem is Tag: .NET Compact Framework PerformanceCounter Smart Device Development

    - Question on removing InstallDir from [CEStrings] section of INF file Regarding a CAB file installation - I have read over-and-over on how to avoid being prompted to install to different storage locations on a mobile device by simply removing the InstallDir line from the [CEStrings] section, and hard-coding the location in the [DestinationDirs] section of the INF file. There's even an MSDN Library article mentioning it dated as late as 04/10/2007 titled "User Selected Installation" at http://msdn2.microsoft.com/en-us/library/aa924404.aspx This does NOT work.

    - Cannot connect to web service on my local machine... The device is connected and cradled. As for the NE2000 card, I have not changed any default settings on the emulator. The problem seems to not be exclusively with the emulator itself because as I mentioned, I get the same problem when trying to browse to the web service through IE on my desktop as well. Any idea what could cause this sort of intermitant problem where at one point it will connect and then it will not and yet at another point it will connect but it will take a very very long time to do so I am being clear enough Really stuck here.

    - Webservice GPRS Connection Hi Guys, I know that by calling a webservice, the connection is automatically setup. Is it possible to force the call to use a specific connection, one that has been setup using the connection manager I would like to be able to control the connection and to close it after use. I have tried using connection manager to first set up a connection and then close it, but it seems that the call to use the webservice creates another connection. Is this correct Or does it grab the existing connection and say "hey, this is mine now" and have exclusive use of it Many thanks, Millicent.

    - Out of memory exception on WinCE5.0 You have a memory leak which you should find and eliminate; forcing GC won’t help you at all. Finding leaks is not easy. I would suggest using “divide and conquer” approach: remove significant part of your application and run the rest, see if memory is leaking and at what rate. You can call GC .GetTotalMemory( true ) to monitor managed memory allocation and P/Invoke GlobalMemoryStatus() (please search if you need a signature) to include native allocation as well. If leak stopped or reduced part of the code you’ve eliminated was leaking. Divide that part to find specific parts. Things to watch for: - Not calling Dispose() on anything what has it (Bitmaps, forms, controls, components, SQL CE and SQL Client objects and so on). - Complex data binding: make sure to set DataSource of list controls and DataGrid to null/Nothing as soon as you no longer need them. - Native interop: make sure to release memory allocated on the native side or unpin objects pinned on managed side.

Speedbit

Hello,

I want to log the memory usage of my application. To do this I want to create a performance counter. But somehow it's not working.

When i define: private System.Diagnostics.per* I see no PerformanceCounter.

As stated here: http://msdn2.microsoft.com/en-us/library/system.diagnostics.performancecounter.aspx

Version Information

.NET Framework.NET Compact Framework

Supported in: 3.0, 2.0, 1.1, 1.0

It should be working in .NET 2.0. I'm using visual studio 2005 and windows CE 5.0.

Any suggestions

Thanks.

Re: .NET Compact Framework PerformanceCounter

Ilya Tumanov

Should be:

.NET Framework

Supported in: 3.0, 2.0, 1.1, 1.0

.NET Compact Framework

<NOTHING>

Which means it’s not supported on any version of NETCF. Since AFAIK CE does not have performance counters, it’s only natural.

Note there was a known bug in documentation generator which would mark classes as supported on NETCF while they don’t even exist in some cases. However, methods are marked correctly. If you run into situation where class marked as supported but does not compile it means you hit that bug. You can check methods to be sure – if none are marked as supported on device, entire class is not available.

Re: .NET Compact Framework PerformanceCounter

mikejo

This was a doc tools bug that has been fixed, but not yet updated on MSDN.

When ".NET Compact Framework" appears at the end of the same line as ".NET Framework" under Version Information, it is extraneous text, and the type/member is not supported.
