 - BluetoothFindFirstDevice help ! 911 Hi guys, I'm stucked with a bluetooth application. Shortly , my visual c++ 2003 bluetooth code is intended to query for devices nearby (example : my cellphone with bluetooh) I'm using the below code; (my code compiles fine, but when I hit the line, BtHandle = BluetoothFindFirstDevice(&search_param, &btDevInfo); I debug and assume that it will wait for querying devices nearby but it immediately switches to dissambler code; I then toogle another breakpoint to another line below this line and resume from debug , it comes to this line and i see that "BtHandle" returns "unknown value" , as if it doesnot query any devices, something wrong occurs here as much as i understand here. Where am i doing wrong here ? Someone please shed a light upon me due i'm stucked at this point. I'm using built-in Widcomm stack in my Win2003 server. Does it matter for this code to work on different stacks? (Microsoft,Widcomm,Toshiba,etc..) Actually, the application i'm working on is intended to work on any machine with bluetooth whatever bluetooth stack it has ? Where do i have to start from ? This is an urgent call, please some experienced guy, direct me in the right order.

 - Adding project reference of CF class library to web service I am using VS.NET 2005, C# I want to expose some of the functionality from my CF class library via web services. I created the web service project and added a reference to my businessServices class library. In this library I include some connection functionality from the SqlServerCE namespace. What ends up happening is that it copies over the SqlServerCe assembly to the Bin directory of the web service under Inetpub and when i try to build the solution it gives the error of: Error 1 Could not load file or assembly 'System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) What is wrong with this and why is it doing this? It seems like it is having rouble loading the assembly because of signed information? Is this an ok process of exposing a device class library via web services?

 - PPC Service for Windows Mobile 5.0 Could anyone please share a Windows Service template that works on Windows Mobile 5.0? I tried to port the service template by Victor Sharov and Vassili Philippov available at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnppcgen/html/ppc_services.asp which works just fine when deployed from eVC++ to the standard emulator, but I just cannot make to work on WM 5.0 emulator. Using the depency tool (Depends.exe) I found out mfc80u.dll and msvcr80.dll are needed so I included those two in my cab file along with the registry settings. Registry is setup just fine and the 3 dlls (2 above plus MyService.dll) are copied to the Windows folder. Device is soft-reseted but service doesn't start at all. Any help is appreciated.

 - Font Metrics I would like to be able to get Font Metrics (Ascent, Descent, Baseline, character widths, etc.) in the .NET CF. How can I do this? It seems pretty nasty to have to use PInvoke on "Coredll.lib" which I assume is a statically linked library (meaning I need to create a DLL that I then PInvoke on). It also requires a device context with a currently set font that it will make measurements on. How do I set the font on a graphics object so that I can make measurements with it? Is there special clean-up involved with this? Thank you, Richard Arthur Tag: AppDomians and memory management. Tag: 66820

 - Using Comma Separated Values to de-serialize a DataSet Subject: Using Comma Separated Values to de-serialize a DataSet The DataSet.ReadXml() speed under Netcf1.0 is slow. It results in our App taking over 60 seconds to start. I have talked to many newsgroups, researched articles, etc to find a way to improve this time. The best answer to date is to upgrade to Netcf2.0. I am in the process of doing this but there may be problems with updating the physical device. One other possibility was mentioned on a newsgroup. That is to use Comma Separated Values rather then Xml to load the DataSet. Does anyone know how that would be done and if any code snippets or examples exist.

 - Code Signing Someone save me from the brink of insanity. I have tried every freaking code sample or thread I have found regarding code signing. I used the very famous code project link, which doesn't seem to work. Here's what I've done. Am I missing something? Code Project Link: http://www.codeproject.com/useritems/signcode.asp 1) I created a cert with makecert 2) I created my pfx file from the cert I made 3) I grabbed the sha1 and base 64 number from the cert and setup the provisioning doc. 4) I created a cab to run the XML and ran the cab on my PDA, it worked just fine. I'm assuming it provisioned correctly. I used the example from code project. 5) I signed another cab file I have with signtool. That worked fine as well. 6) I installed the cab file on the PDA and was promped because it was from an unknown publisher. WTF! Do I need a mobile to market cert? I thought I read that I wouldn't get this prompt if I signed the cab file and its assemblies. I don't get this prompt after the first install, but I don't want to see that prompt at all. Someone please help. Thanks in advance! Tag: AppDomians and memory management. Tag: 66814

 - Making an application full screen for Windows CE 4.2 using C# .net This took me a while to figure out because everyone says something different, and none of them worked for me. So when i got it, I decided to post the solution to prevent it from happening to others. Here we go. You have to do two things. First, find the taskbar, then move it. Then move you're main window. , assuming a screen size of 240x320. Also, you have to make a bunch of Win32 API calls to do it. [Flags()] public enum FullScreenFlags : int { SwHide = 0, ShowTaskbar = 0x1, HideTaskbar = 0x2, ShowSipButton = 0x4, HideSipButton = 0x8, SwRestore = 9, ShowStartIcon = 0x10, HideStartIcon = 0x20 } // Win32 API Calls [DllImport("coredll.dll")] private static extern IntPtr GetCapture(); [DllImport("coredll.dll")] private static extern IntPtr SetCapture(IntPtr hWnd); [DllImport("aygshell.dll", SetLastError=true)] private static extern bool SHFullScreen(IntPtr hwnd, int state); [DllImport("coredll.dll", SetLastError=true)] private static extern IntPtr FindWindowW(string lpClass, string lpWindow); [DllImport("coredll.dll", SetLastError=true)] private static extern IntPtr MoveWindow(IntPtr hwnd, int x, int y, int w, int l, int repaint); public static IntPtr GetHWnd(Control c) { IntPtr hOldWnd = GetCapture(); c.Capture = true; IntPtr hWnd = GetCapture(); c.Capture = false; SetCapture(hOldWnd); return hWnd; } public static void SetFullScreen(Control c) { IntPtr iptr = SystemHooks.GetHWnd(c); SHFullScreen(iptr, (int)FullScreenFlags.HideStartIcon); // move the viewing window north 24 pixels to get rid of the command bar MoveWindow(iptr, 0, -24, 240, 344, 1); // move the task bar south 24 pixels so that its not visible anylonger IntPtr iptrTB = FindWindowW("HHTaskBar", null); MoveWindow(iptrTB, 0, 320, 240, 24, 1); } public static void UnsetFullScreen(Control c) { IntPtr iptr = SystemHooks.GetHWnd(c); SHFullScreen(iptr, (int)FullScreenFlags.ShowStartIcon); MoveWindow(iptr, 0, 0, 240, 296, 1); IntPtr iptrTB = FindWindowW("HHTaskBar", null); MoveWindow(iptrTB, 0, 296, 240, 24, 1); } 'Control c' is the main control you're passing in, which should be your main view.

 - Use reflection for User Interface testing I'm having difficulties getting a test application to work. The application being tested runs on Pocket PC 2003 and uses the dotNet Compact Framework 2.0. To be able to test our application we wrote a test application based on information in an MSDN Magazine article that used reflection for User Interface testing. See http://msdn.microsoft.com/msdnmag/issues/05/01/TestRun/. In our case the application being tested is somewhat more complex. To successfully run the application the Main method must be executed. When using the suggested Assembly.CreateInstance the application will raise an exception. This because the CreateInstance method will run the constructor. However, to run the application, the main method must be executed. While looking for other solutions I came across a method that I was looking for. I am able to run the application in a separate thread and run the Main method. This makes use of the AppDomain.ExecuteAssembly method. The problem is that I need an object handle for the application. I also tried to invoke the Main method after creating an instance of the application. This causes an exception as well because the constructor will be executed twice. I think the best solution would be to use the ExecuteAssembly method and get an object handle. But I cannot find a way to do that. Solutions or alternatives are muchly appreciatedâ?¦ Tag: AppDomians and memory management. Tag: 66730

 - Interprocess .netcf & com I guys, tiziano fabbri wrote. I have a demand on my new project: send event from com dll to a .netcf application, may be in the future from .netcf to com dll also. I don't want use ATL. Only Win32 dlls. I found a good document named "Inter process com in NETCF", it is regarding the inter process comm inside world NETCF, but I tryed to use this experience to adapt code and have same effect between NETCF and COM. Obviously does't run !! First, my com event is declared in a remote class of the complexive Com DLL, that could be a reason of no event intercepting using a double declaration, one in COM and the same in NETCF by the name because there is a decoration of the event's name ?? . COM declaration: mCpCoreREvent = CreateEvent(NULL, true, false, LPTSTR ("CpCoreREvent")); (when i need I set the event by SetEvent(mCpCoreREvent)) NETCF declaration/catching method in a thread (I wrapped coredll.dll) private void listenCpCoreDataCommunication() { IntPtr hWndR = Core.CreateEvent(true, false, "CpCoreREvent"); // Loop until stopped while (listenerCpCoreDataActive) { // Catch the event if (Core.Wait.Object == Core.WaitForSingleObject(hWndR, 1000)) { Core.ResetEvent(hWndR); if (!listenerCpCoreDataActive) break; //Visualizzo i dati this.Invoke(new EventHandler(showDebugCpCoreSJA1000)); } } Core.SetEvent(hWndR); Thread.Sleep(100); Core.CloseHandle(hWndR); } I tryed to move the declaration of the com event in the main body of dll, just to try, but I haven't effect in NETCF program. Please, some one have a tip for me ?? thank you, fabbrit Tag: AppDomians and memory management. Tag: 66708

 - Key event logger Hi, For a usability study I would like to create some software that runs as a service in the background and logs all key events for all programs. In the end you would get a list of all key strokes and some context information e.g. which program was active or the name of the form. Would that be possible to make for Windows Mobile 5?

 - C# newbie question I am creating a database app in MSVS 2005. I have created the mobile database and it seems to work with the program. I have inserted a few records for testing in VS 2005. Those records show up iwhen the program runs in the emulator. I created a datagrid form by dragging the grid from the datasources page in my app. after doing so I noticed a right pointing arrow at the top of the grid allowing me to let MSVS build my summary and Edit forms. So I did. However when I add a new horse or horses they seem to be saved to the table and displayed in the datagrid, but only until I close the datagrid form(not the application) then when I re open it the records I created while my app was running in the emulator are no longer there. So I adde this code to the close of the edit form, but still no luck in saving the records. Can anyone tell me what Iam doing wrong. this.horseBindingSource.EndEdit(); this was added by MSVS I added this below:no errors but data not saved FB7MobileDBDataSet fb7mobiledataset = new FB7MobileDBDataSet(); FB7MobileDBDataSet.HorseDataTable newhorse = (FB7MobileDBDataSet.HorseDataTable) fb7mobiledataset.Horse.GetChanges(DataRowState.Added); try { if (newhorse !=null) { horseTableAdapter1.Update(newhorse); } fb7mobiledataset.AcceptChanges(); } catch (System.Exception ex) { MessageBox.Show("UpdateFailed"); } finally { if (newhorse != null) { newhorse.Dispose(); } } Tag: AppDomians and memory management.

 - Hiding Windows Start Button VB 2005 / Pocket PC. Is it possible to hide the Windows Start Button and keep it hidden even after my program exits? I know how to hide it temporarily using this: Dim hwnd As IntPtr = GetForegroundWindow() SHFullScreen(hwnd, SHFS_HIDETASKBAR) But I don't know what handle to use to make it permanent (or at least until a reset is performed). Note that I don't want to disable the whole taskbar. I need other programs to keep their "Ok" button in the upper right so they can close. I've search through a zillion older messages here and didn't see a solution. -- Kent Briggs, kbriggs@spamcop.net Briggs Softworks, http://www.briggsoft.com Tag: AppDomians and memory management.

 - best practice for deregistering events -= ? Hi, I'm working with someone else's code and have an issue with the application design for registering and de-registering events. In the existing code... Events are registered as shown below. If the routine that owns this code is executed unexpectedly more than once. Then there can be more than one registration for the event. blah.blahChanged += new EventHandler(this.blahButton_BlahChanged); Also, the existing code uses the dispose event to deregister the events as shown below. public virtual void Dispose() { blah.blah-= new KeyEventHandler(blah); blah.blah-= new KeyEventHandler(blah); blah.blah-= new KeyEventHandler(blah); } Then the existing code forces a garbage collection using GC.Collect; Is this a bad thing??? Is it ok to use the dispose method to deregister events by forcing a garbage collection? I prefer to use this method... blah.blahChanged -= new EventHandler(this.blahButton_BlahChanged); blah.blahChanged += new EventHandler(this.blahButton_BlahChanged); it ensures that only one registration exists. I deregister events in other locations. not in the dispose routines? Comments? Tag: AppDomians and memory management. Tag: 66691

 - wce300 VS wce400, ARM VS ARMV4? What is the difference between wce300 and wce400 cab files when deploying to a mobile device? For instance I have a PDA with Windows 2002 with a PXA225 processor and a PDA with Windows 2003 SE and a Samsung S3C2440 processor. Guess I'm not really sure if are platform dependant (Windows CE vs Pocket PC), OS dependant (Win. 2002 vs Win. 2003) or processor dependant. Also are there any hard rules on when to use ARM and ARMV4 cabs? Thank for any response, Dave M. Tag: AppDomians and memory management. Tag: 66688

Do appdomains in one process share JIT-code?

I don't see why they wouldn't.
