    - regarding the animation in separate thread That would work as long as your animation is done in memory and not shown on the screen. If you need to show it (which is usually the point of animation) you have to use Control.Invoke() to at least update the screen which would wait for UI thread which turns your threading pretty much useless.

    - Debugging Webservice from Device You can provide correct URL (not localhost which is not going to work unless application is running on a Web Server itself) at the time you're adding web reference. Or you can set it at runtime by setting Url property of the generated proxy class: myWebService = new MyWebService(); myWebService.Url = @" http://gauls/trysite/Service.asmx "; Tag: Smart Devices VB and C# Projects Application is lost when power goes off Smart Device Development

    - 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: Smart Devices VB and C# Projects Application is lost when power goes off Smart Device Development

    - Installation of Compact Framework 2.0 failed. Why? Yes, you need to free up as much program memory as possible. Remove all applications from startup, all today plug-ins, reset the device and try installing NETCF as soon as OS is loaded.

    - Info using data from database in application Hi AKD, In my opinion, what you want is just Parameterized Queries in your database. Use SqlCeParameter to set the parameter in your select statement.

    - Combo Box display mbr Eventually found the solution to this. When you drag a field to a form as a Combobox it defaults the data binding to the Text property. You have to change this to bind the SelectedValue (Databindings section of Properties) to the underlying field in the Table. Then it all works. Thanks to the new Mobile Dev. Handbook (Wigley/Moth/Foot ) for this info. Tag: Smart Devices VB and C# Projects Application is lost when power goes off Smart Device Development

    - embedding and updating content I 'd suggest that you put your different contents in different divs. Like with normal webpages you make another page. Then you can use removeChild and appendChild to change the content of your gadget. Something like: function SwichContent() { if (m_el.appendChild(divA)) { m_el.removeChild(divA); m_el.appendChild(divB); } else { return null; } } Tag: Smart Devices VB and C# Projects Application is lost when power goes off 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: Smart Devices VB and C# Projects Application is lost when power goes off Smart Device Development

    - File upload with Sidebar Gadget You can manipulate the local file system. You can read a file to upload via XMLHttpRequest, using an FSO binary stream. If you want to allow the user to select a file, use System.Shell.chooseFile. Combining the two: var adTypeBinary = 1; var cfItem = System.Shell.chooseFile(true, "Word Files:*.doc:Text Files:*.txt::", "", ""); if (cfItem.path != "") { oStream = new ActiveXObject("ADODB.Stream"); oStream.Type = adTypeBinary; oStream.Open; oStream.LoadFromFile(cfItem.path); content = oStream.Read; //upload content oStream.Close; oStream = null; } Tag: Smart Devices VB and C# Projects Application is lost when power goes off Smart Device Development

    - PerformanceCounter 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.

    - 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: Smart Devices VB and C# Projects Application is lost when power goes off 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: Smart Devices VB and C# Projects Application is lost when power goes off Smart Device Development

    - Redistribution of .net framework 2.0 If you're planning to support all the processors and OS then put all the CABs. If you're planning to support only ARM processor then put just ARM. There are 4 ��just�� ARM CABs, by the way: PPC 2003, WM 5.0, CE 4.5 and CE 5. You probably need PPC 2003 and WM 5.0 CABs (unless your customer asked you to develop for specific Windows CE device). Anyway, all you have to do is to list CABs for different processors in the INI and CeAppMgr.exe would pick the correct one for you based on connected device. You could read about that feature on MSDN. Tag: Smart Devices VB and C# Projects Application is lost when power goes off Smart Device Development

    - 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 Hi My experience is that you need to call GC.Collect() at appropriate times in your application. You shouldn't call it in a tight loop, but in close events and at the end of doing things. If you haven't already you should build a memory manager to keep track of memory available, making memory statistics etc -Raymond Tag: Smart Devices VB and C# Projects Application is lost when power goes off Smart Device Development

    - Get Camera Data without showing on the screen? JasonFuller wrote: You can't use the SHCameraCapture API. You'll have to use DirectShow directly. See the "Cameracapture" sample in the SDK. I tried Cameracapture sample, but had these two problems: 1. There is no way to control the exposure, and the resulting picture is alway whited out. 2. Many photos ended up currupt with zero size. I think SHCameraCapture is much simplier and WYSIWYG. But can't be used to automatically take pictures. Or maybe it can, if one sends two center rocker clicking events to it.

Hi,

I have created a C# .Net Compact Framework application which runs well on PDAs.

The problem is that when the battery goes completely flat, my application which was installed is also gone.

So user has to reinstall the application when they bring back power

How Can I avoid that .

Regards

Mani

Re: Smart Devices VB and C# Projects Application is lost when power goes off

Ilya Tumanov

This is normal for devices with RAM based storage. To avoid that you need a device with persistent storage (e.g. Windows Mobile 5.0 based). If you can��t get such device, you would have to reinstall everything in case battery runs out.

Re: Smart Devices VB and C# Projects Application is lost when power goes off

pmanisekaran

Hi,

Thanks for that. My device is Windows CE 5.0. Is Windows Mobile 5.0 different from Windows CE 5.0 If it is not different How do I install to persistent storage

Regards

Mani

Re: Smart Devices VB and C# Projects Application is lost when power goes off

Ilya Tumanov

Yes, Windows CE 5.0 is different from Windows Mobile 5.0. Windows CE is highly customizable modular OS and Windows Mobile is a particular customization of Windows CE with special UI, set of PIM applications and persistent storage.
