    - Compact Framework CLR Profiler I am trying to make use of the .NETCF CLR profiler that was recently released separate from the 3.5 beta compact framework sdk: http://www.microsoft.com/downloads/details.aspx?FamilyId=C8174C14-A27D-4148-BF01-86C2E0953EAB&displaylang=en I have been able to use it to successfully launch a simple example application (both via IP and via active sync), but shortly after the application starts up, the profiler running on the desktop throws this error - confusing since the application actually pulls up after using the profiler to start it: This operation returned because the timeout period expired. (Exception from HRESULT: 0x800705B4) I have been able to get the Remote Performance Monitor tool to work, but not the profiler, and I would appreciate any help anyone might be able to give.

    - Exception in method called by Invoke When my CF1 application starts up, it loads its main form: static void Main() { try { Application.Run(new MainForm()); } catch(Exception e) { MessageBox.Show("Unhandled error: " + e.Message, "My App", MessageBoxButtons.OK, MessageBoxIcon.Hand, MessageBoxDefaultButton.Button1); } } In its OnLoad method, the new form starts a thread. When the thread is done, it calls Invoke(). The invoked method is throwing an exception. The exception is caught by the try/catch block above in main, and the application exits. It appears the thread is still running, presumably blocking on the Invoke. (I put a breakpoint after the Invoke, and it's never hit. The debugger doesn't close either.) Can anyone tell me what I'm doing wrong here? What's the correct way to approach this? Regards, David PS- As an aside, on some devices (e.g., iPaq running 2003SE) the MessageBox above beeps and immediately closes. Why is that? Tag: Handles Surviving Tag: 83809

    - NullReferenceException while Deserializing in Web Services I have upgraded a .Net CF 1.0 project to .NET CF 2.0 using VS.NET 2005. The project makes calls to Web Services written in Java and it has been working fine in CF 1.0. I have also upgraded the Web Reference using the existing WSDL. The proxy has been created properly. However after the upgrade I can call only few of the Web Methods and some of the web methods failed with NullReferenceException during Deserialization process. I have noticed some changes in reference.cs as below.. Decimal types were declared as System.Nullable<decimal> etc. I tried by changing this back to System.Decimal instead of using nullable types, but this did not help either. The stack also doesn't give any relevant information except saying that the call failed due to NullReferenceException.

    - Regarding hosting Flash ActiveX control in CF2.0 Hi, I saw Mr.Alex Feinman's webcast regarding "COM and DOT Interop in CF2" at http://blog.opennetcf.org/afeinman/PermaLink,guid,1dfc3c39-d3cc-4faa-b5f6-cb5c9aed61dd.aspx I have a question regarding the section on hosting activex controls in CF2.0. I tried out what he had suggested and I was able to successfully host a Flash player activex control for PPC inside a CF2.0 C# application. But I am running into one problem. I am building a projector application for a Windows CE 5.0 device. So my requirement is that I need to embed the flash movie inside my application. I tired to set the EmbedMovie property in the designer and also specify the path of the flash file (I gave the path on the development PC where the actual swf file is stored, assuming it is going to embed it in the application during design time) for the Movie property. But this does not embed the movie inside the application. Is there something I am missing or is this not possible when we host an activex control in CF2.0 by the method he had suggested? Any help is greatly appreciated. Thanks, Jothishankar Tag: Handles Surviving Tag: 83778

    - specifying CEAppMgr destination directory for persistent CAB files Is there a way to tell CEAppMgr where to place my CAB files before installing them, and to not delete them after install? I can successfully deploy my app to CE5 devices using CEAppMgr. The multiple CAB files all get installed to the correct locations, then get deleted. In an effort to allow my app to be reinstalled following cold boots, I have created registry files in the "Application" directory that look for and relaunch the CAB files upon cold boot (Symbol MC3000 system). This works if I manually place the CAB files in the nonvolatile "Application" directory where the REG file is set to look for them. However, I cannot figure out how to direct CEAppMgr to place and leave the CAB files in the "Application" directory during my automatic install. My install process is a self-extracting ZIP that unzips the 5 CABs and corresponding .INIs to a temp dir on the users PC. It then launches a bat file that calls CEAppMgr passing the 5 .INI files. This works great, my app and supporting CABs (CF, SQL CE, etc) all get installed correctly, but after it runs, the CAB files themselves are deleted, so the auto reinstall after cold boots fail.

    - Read Values of Registry Key Hello, I am trying to create a setup.dll file. In the "Install_Exit" part of Setup.dll i am trying to find if .net compact framework is installed or not. My knowledge of evc++ is minimal. I understand from what i read, that i should use RegOpenKeyEx : RegOpenKeyEx(HKEY_LOCAL_MACHINE,_T("SOFTWARE\\Microsoft\ \.NETCompactFramework"),0,0,&key) After i open this how do i read the values of this key. I will need the values to know which version of .NET CF is installed on the system. I read some where that it would be 2.0.0.0 for .NET CF 2.0, but when i checked that value on my PPC using remote registry editor, that value was 2.0.5238.00. So my question is, is there any way with which i can read these values programmatically. And i guess i can assume that if any of these values starts with "2.0", then .Net CF is installed. Also it would be great if some one could point me to some link where i can open a web link programmatically from this setup.dll in IE. In this link i intend to place the .NET CF binaries for the user to download. Thanks in advance and Regards, Rithesh Tag: Handles Surviving Tag: 83757

    - Dialog and Databindings I've read a lot of this in newsgroups, but didn't find an answer. And on my app it still doesn't work as I want. Just what am I doing. I have a form (dialog, MinimizeBox is set to false). On that form are some TextBoxes which Text property is bound to an objects properties. The form has the "OK" on the page header and a Button on it which shall act as "Cancel" First I thought that the Form.DialogResult influences whether the bound controls expose there values to the properties or not. This doesn't seem so. How can I determine if the object properties are updated or not when using databinding? Second, changing a value in a TextBox, leaving the focus in that TextBox and clicking the "OK" does not update the bound property. What have I to do to handle the focus propbelm properly?

    - No free slot for more dll's Hi, I've got a project with heavy graphic elements (picture boxes, image lists etc). At some point of development I needed additional dll's but I can't load them since I'm out of "dll's memory" slots. I thought of several solutions: 1) generate a seperate exe utility that is activated from the main exe, and is actually an interface to the dll. (did that. takes too long for the exe to load each time I need it). 2) Use the same utility as a tcp/ip server. did that. for some reason, the utility is ending with "native error"... and restarted automatically by my software. 3) Use messaging. 4) try to load the bitmaps on the fly, only the needed ones. This way I might free enough space for the additional dll. My questions: 1) Are there any other solutions? 2) What is your opinion about the best way to solve it? 3) How can I check to see how far am I from being able to load additional dll('s) ?

    - Different values for same formula Hi all, does anyone know why the following code gives me totally different results when running on the Windows Mobile 5 emulator and a real Windows Mobile 6 device? I am trying to find out the distance in metres between 2 GPS points. It works correctly on the emulator but the WM6 device gives bizarre values! Values given are: WM5: 0.84912711886472536 & WM6: 50481 Call to function: CalculateDistance(40.44717, -3.63763, 40.44717, -3.63762) Please help as I am totally lost!

    - .Net CF TabControl Color Does anyone know how to change the tab backcolor? As is now, you can change the tab pages to any color you want, but the tabs themselves are still ugly gray. I've searched high and low and have found one commercial control, but it's more then I want to pay. Any ideas on how to do this using subclassing or p/invoke? Thanks.

    - Doesn't make sense at all.......send/recv in socket... Hi, It makes me crazy.......I can't figure it out why it is happening at all...so strange.. Here is the how system works... Development environment. Client : .NET Compact Framework 2.0/PPC Server: .NET Framework 2.0 PPC connects to the server to transfer a file. Client code in PPC As you can guess, fs is FileStream. --- byte[] buf = new buffer[8192]; int bytRead = fs.Read(buf, 0, buf.Length); while (bytRead > 0) { _socket.Send(buf, 0, bytRead, SocketFlags.None); bytRead = fs.Read(buf, 0, buf.Length); } _socket.Close(); --- Server code in the desktop fs is FileStream. --- int rBytes = 0; byte[] buf = new byte[8192]; do { rBytes = client.Receive(buf, 0, buf.Length, SocketFlags.None); fs.Write(buf, 0, rBytes); } while ( rBytes > 0 ); client.Close(); --------------- When I tested these, it works perfectly under Wireless connection. HOWEVER, the problem arise when testing this with the cradled device. With the cradled device, the server ONLY receives 99% data. For example, if I send a file (162KB) from the PPC, the server ONLY receives 161KB. I tried to fix possible soultions as best as I can...However, I can't figure out how this works WITH THE CRADLED device. Once I take off the device from the cradle, then test under wireless connection, it WORKS perfectly..... It is so strange......Why the server ONLY receives 99% when the PPC cradles????? Any help would be appreciated. Thanks, ..........................................................TJ Tag: Handles Surviving Tag: 83627

    - Strange sudden shutdown issue with CF app Hi, We have created an app that basically connects to a web service gets data, then stores it locally on the device, and when a record needs to be modified/added the system first tries to connect the web server sees if its availible, if not then it stores in locally on the device until the connection comes back, now I noticed that if the device does not mess around with the data connection then the application sits nicely as long as its open, and never gets shut down (unless the system automatically shuts it down due to memory constraints). However on devices that has a phone, and even more if the device is connected to an exchange server with push email and/or there are calls for a longer period of time, if you go back to the application afterword and while doing basically anything that worked before (before a lengthy call or so, don't know really what is causing but I've seen some indication that this might be the case) like a charm but now doing that same action will blow out the program, most of the times without any exception, and sometimes I would get NullReferenceException and the trace will show really basic internal trace, and everytime something else where the same action before worked just fine, and also note that those exceptions point no where to anything related to the connectivity of the device, but mostly front end stuff. But again most of the time I get no exception at all but just simply disappears. It might be that there are some external native exception that is not being chought but am puzzled at where to start looking. Hope someone might come up with some, as I'm puzzled and dont know where to focus on. Regards and thanks in advance Shloma Tag: Handles Surviving Tag: 83617

    - Drag-and-drop graphics in CF.NET? I could spend 15 minutes describing what I mean by this, or I could just point everyone to a link: http://tinyurl.com/2mu2bb This simple "Master Mind" application allows a user to drag a bubble from the right-hand legend to the playing board. This could be useful for all kinds of applications, showing a nesting of one thing into a larger thing. This project, unfortunately, makes use of GDI+ and therefore these classes aren't supported: GraphicsPath, PathGradientBrush, Graphics::FillPath, Graphics::DrawArc, etc. Has anyone seen a similar sample showing drag and drop for CF.NET?

    - Combobox Select String API not working. Hi All I am trying to Select an item in a combobox on a form running in a different application(written in C# CF2.0) and running in a different process using the windows API. I am developing with C# CF2. This is my code and it always returns -1. I know the text is in the combobox And the Handle is defiantly correct for that combobox, because I can send a screen tap to it and the list will drop down. Please can some one take a look and let me know where I am going wrong. uint CB_SELECTSTRING = 0x014d; [DllImport("coredll.dll", EntryPoint = "SendMessage", CharSet = CharSet.Auto)] // static extern int SendMessage4(IntPtr hWnd, uint Msg, int wParam, string lParam); public int ComboBoxSelectString(IntPtr hWnd, string s, int StartAtIndex) { return SendMessage4(hWnd, CB_SELECTSTRING, StartAtIndex, s); } Thanks, ink Tag: Handles Surviving Tag: 83610

    - Absolete API's in .Net CF 2.0 Hi All, I would like to know the Absolete API's in .Net CF 2.0 over 1.0. This is required to migrate my mobile application to latest version of CF -- happy coding, kotteesh Tag: Handles Surviving Tag: 83608

When profiling a simple app just to get a feel for how to use the CLR
profiler, I notice that there are 5 "Handles Surviving" after exiting the
application. I'm having a little bit of a struggle with what this should be
telling me. When I dig into the graphs, none of the surviving handles are
coming from any classes or methods written by me - they seem to all be coming
from the form and standard .net controls on it...I just have a form that I
dragged three buttons and a checkbox onto - I think these must be the five
handles (and I think this is confirmed by the allocation graph for "Handles
Surviving")...So I guess I don't have a question so much as I would like
validation, and maybe an idea of what to watch out for in a more real-world
scenario.
