    - TimeSpan calculation error Hi, Assuming dt1 and dt0 (DateTime structs) represent times about or less than one second apart, then using: (dt1 - dt0).TotalSeconds (or TotalMilliSeconds, or dt1.Subtract (dt0)) returns 0.0 *or* 1.0 whereas on the desktop, .NET can return any value between 0.0 and 1.0. Is this a known issue? Hilton Tag: vb.net Tag: 87287

    - Failed HttpWebRequest to an HTTPS server takes 100% of CPU We have a CE 5.0 application (.NET CF 2.0) that we use to download files from both secure and non-secure servers over HTTP and HTTPS. When making a request to a misconfigured server over HTTPS, we noticed that the CPU on our device would jump to 100% and stay there indefinately. We traced this to a thread that appears to be created when calling HttpWebRequest.GetResponse(). It appears that when we make a request to this specific server, the TCP connection gets established and the client sends its "Client Hello" message to the server. The server immediately closes the connection (you can see the FIN-ACK from the server over Wireshark). Here is where the problem occurs: If you are making this request from a client PC using the full .NET framework, the client completes the handshake by sending its own FIN and the connection is closed. HttpWebRequest.GetResponse() returns immediately with an error stating that the server closed the connection. However, if you are making this request from a CE 5.0 client running the compact framework, the connection never gets closed from the client side. Instead, HttpWebRequest.GetResponse() does not return until the specified timeout expires. In addition to this, even after calling Abort() on the request object, a thread is leftover that seems to spin forever and takes up 100% of the CPU. This does not appear to happen when making non-HTTPS requests, nor when making requests to a properly configured server or a server that is not listening on port 443 at all. I was able to recreate this easily by writing a simple test server that runs on Windows XP (in C++) and test client for CE in C#. The test server listens for a TCP connection on a port, accepts a connection, receives one packet and then closes the socket. The test client simply creates an HttpWebRequest object for the specified server and port and calls GetResponse(). Every time (repeatable on more than one device and more than one computer hosting the server) the call to GetResponse() will result in a spawned thread that eats up the CPU. Again, calling Abort() on the request object does not seem to clean things up. Does anyone have any ideas? I have pasted the code below, but can send the solution files if required. ================================================ SimpleTCPServer (C++ Win32) ================================================ #include <winsock2.h> #include <windows.h> #include <stdio.h> #define LISTEN_PORT 9091 int _tmain (int argc, TCHAR* argv[]) { WSADATA wsaData; SOCKET sock = INVALID_SOCKET; sockaddr_in local; SOCKET client; sockaddr_in from; int fromlen=sizeof(from); char buf[512]; // initialize WinSock if(WSAStartup(MAKEWORD(2,2), &wsaData)) { printf("WSAStartup() failed\r\n"); return 0; } while(true) { // create socket local.sin_family=AF_INET; local.sin_addr.s_addr=INADDR_ANY; local.sin_port=htons((u_short)LISTEN_PORT); sock = socket(AF_INET, SOCK_STREAM, 0); if(sock == INVALID_SOCKET) { printf("socket() failed\r\n"); WSACleanup(); return 0; } // bind if(bind(sock, (sockaddr*)&local, sizeof(local))!=0) { printf("bind() failed\r\n"); closesocket(sock); WSACleanup(); return 0; } //listen if (listen(sock, 5) != 0) { printf("listen() failed\r\n"); closesocket(sock); WSACleanup(); return 0; } // accept the connection printf("Waiting for client to connect on port %d...\r\n", LISTEN_PORT); client = accept(sock, (struct sockaddr*)&from, &fromlen); printf("Accepted TCP connection from %s\r\n", inet_ntoa(from.sin_addr)); // receive the first packet int bytes = recvfrom(client, buf, sizeof(buf), 0, (struct sockaddr*)&from, &fromlen); printf("Received %d bytes from client\r\n", bytes); // close the connection printf("Closing connection\r\n\r\n", bytes); closesocket(client); shutdown(sock, SD_BOTH); closesocket(sock); } WSACleanup(); return 0; } ================================================ SSLClient (CE 5.0, .NET CF 2.0) (just a blank form with a "Send" button on it) ================================================ ... private const string SERVER = "192.168.1.92"; private const int PORT = 9091; private void SendSSLRequest() { HttpWebRequest request = null; HttpWebResponse response = null; try { request = (HttpWebRequest)(WebRequest.Create("https://" + SERVER.ToString() + ":" + PORT.ToString() + "/")); request.Timeout = 5000; request.ReadWriteTimeout = 5000; response = (HttpWebResponse)request.GetResponse(); } catch (Exception ex) { } finally { if (response != null) { response.Close(); response = null; } if (request != null) { request.Abort(); request = null; } } } Tag: vb.net Tag: 87282

    - Enum property of custom control does not appear in VS2005/2008 (C# Hi, I created a .NET CF custom control with a standard type (int) property and a custom one (enum) like this: public enum EnumTest { Value0, Value1, Value2 } When a./ I use an import method using [DllImport()] or b./ I declare any other device-specific field (e.g. field from Microsoft.WindowsCE.Forms.MessageWindow) the enum property of my custom control class does not appear in the Visual Studio property editor. There is not necessary to use the imported method or anything from the MessageWindow field. In addition, there is no error/warning message about VS's problem. Otherwise, the standard typed property (int) appears correctly in this case. My questions are: 1. How can I make visible my custom typed (enum) property in the designer? 2. Enum is not a device-specific part of my control but the VS does not display it. Why? I would appreciate it if anybody would help me. Thanks! Tag: vb.net Tag: 87281

    - Debug a CF application on a PC Hi I know its possible to run a CF application on a normal PC. But is it possible to debug it? I would like to start writting my application on a PC first. Its faster and much easier to debug the functionality on the PC. When I uses a normal projekt it uses the full framework and I have to dobbel check if I have used som function not in the CF. I have added reference to the CF version of System.Windows.Forms, System.* etc instead of those from the full framework. If I then uses some unsupported function I get compile errors. But the problem i, that when I edit the dialog or add new controls, unsupported functionality is added by Visual Studio 2005. If I create a CF projekt, Visual Studio launches an emulator instead and I cant debug on the PC Is it possible to make Visual Studio not launching an emulator when debugging of a CF application? Is it possible to tell VS, just to add/use CF compatible functions on controls? /Thomas Tag: vb.net Tag: 87279

    - How to write IExtenderProvider control for .NET CF? Hi, I searched all over the net and I can't find no info how to do this, other then this post http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=158930&SiteID=1. I would like to rewrite this example http://msdn2.microsoft.com/en-us/library/system.componentmodel.iextenderprovider.aspx for Compact Framework, and I would like to do it VS2005 way. VS2005 suggests to use .xmta file which will produce *.PocketPC.asmmeta.dll file. The article I found also suggests to create yet another library where the designer would be. Does this mean that now instead of distributing two libraries (one for runtime one for design time) I have to distribute three (an extra *.PocketPC.asmmeta.dll)? I have a hard time to believe it. Can anyone shed some information on this? Thank you. Rastio. Tag: vb.net Tag: 87258

    - Memory problem with SqlCeEngine.Compact Hi all, We are having a memory leak, in our application. The problem is that we only can reproduce it 3 times. And we cannot find the pattern of this bug. In our application when the user finishes one special section, an automatically full backup is executed (If the users setup it in this way). Our backup does this: ///close all DReaders, Dcomad's, and connections to de DB SqlCeEngine engine = new SqlCeEngine("Data Source = DB.sdf")); engine.Compact("Data Source='"DBBK.sdf ";"); engine.Dispose(); /// open connection again to the DB.sdf The error we log is this: Error Message: Not enough storage is available to complete this operation. Stack Trace: at System.Data.SqlServerCe.SqlCeEngine.ProcessResults() at System.Data.SqlServerCe.SqlCeEngine.Repair() at System.Data.SqlServerCe.SqlCeEngine.Compact() at Backup.CompactDatabaseBackUp() at Backup.CreateBackUp() at BackUpControl.DoBackUp() We are using CF 2.0, and the bug was reproduce with a 3 MB DB. As I tell you before, this happens occasionally. So I don't know what to do, I call the GC.Collect or GC.WaitForPendingFinalizers always before SqlCeEngine.Compact is call?, or do I have any way to know how memory is at the moment, and if is necessary I call GC.Collect ?

I have found an example of a person using it claing to be in the CF world... But I get a compile error that TypeConverter is not an attribute class. MSDN seems to show that it isn't supported which would back up the compiler error. Here is a link to the example that I found: http://groups.google.com/group/microsoft.public.dotnet.framework.compactframework/browse_thread/thread/52fe4d21322edafb/4d3059ecce1ed73d?lnk=gst&q=typeconverter#4d3059ecce1ed73d What I'm trying to do is databind an object without using the Parse and Format methods. In the full framework we have implemented this by creating a class derived from TypeConverter and all of our Business Objects specify this class by using the TypeConverter attribute. Does anybody know how I can convert a string to my Business Object in the business layer (textbox binding). Right now I have to do it in the UI layer using code like this... private void orderNumberBinding_Parse( object sender, ConvertEventArgs e ) { e.Value = new OrderNumber( e.Value as string ); } Any help is appreciated.

    - Can Compact WCF be extended for duplex communication? I am trying to confirm whether duplex communication is at all possible using .NET Compact Framework support for WCF. Our Windows CE device is not a mobile device and I would think some sort of duplex communication should be supported. However, I see where only basic http & custom bindings are supported. Basic Http obviously won't meet my needs, but I also don't even see how custom bindings can help me. I would need to write a custom channel, but it doesn't seem that will meet my goals either. ChannelBase is supported by the Compact Framework, however IDuplexChannel is not. I guess I'm looking for comfirmation ( positive or negative) on whether Compact WCF can be extended to support duplex communication w/ a device running Windows CE.

    - Message queues This is all .NET 3.5 with Visual Studio 2008 I have a simple app on Windows Vista-64 that creates a messaging queue. FormatName:DIRECT=OS:david-1\private$\callerid. The app then writes a couple of entries. I have verified that the entries have been correctly created with the Computer Management tool. I now have a simple app written for the compact framework on an HP iPAQ HP 2790. MSMQ has been installed on it. When I call MessageQueue.Exists(@"david-1\private$\callerid"), it returns false. I can call this code: IPAddress[] addresses = Dns.GetHostEntry("david-1").AddressList; and the correct address comes back so I know networking and dns are working properly. Is there something special that I have to do on the Vista-64 machine or on the iPAQ to make this work? Tag: vb.net Tag: 87155

    - How to create a floating/resizable/movable dialog/form without I want to create a floating dialog/window that when moved resembles the way a MessageBox is moved. When you bring up a MessageBox and click on the title and drag the MessageBox to a different location, a frame (also known as border or rectangle) appears over the dimensions of the MessageBox and while you drag the MessageBox, only this frame moves while the content area of the frame is transparent. I have looked up solutions for creating transparent controls but I believe that this is the wrong solution. For starters, when a MessageBox is moved, there is no flickering at all. This tells me that the frame is probably not a control of any sorts, because if it were it would require that the background be updated very quickly and this does not appear possible using anything that inherits from a base control. I believe that the frame is being drawn as a rectangle on top of a bitmap of the entire form (or entire screen) and that double buffering must be used to eliminate flickering. In fact, I wouldn't be surprised that only the grahic areas behind the actual frame lines are being updated and nothing within the frame. This allows for the fastest updating possible while the frame is being moved around. So, it's possible that when a mouse down even is detected by the MessageBox control on the title area, a snapshot of the entire form or screen is taken and then a rectangle is drawn at the same location where the MessageBox is located. When the user moves the mouse while it is down, the code is effectively redrawing the frame on a different location of the snapshot. Then again, maybe I am wrong. Perhaps the drawing of this MessageBox is an internal piece of code that access the drawing buffer of the device and simply just draws on it. If this is so, I am not aware of whether there is an API that would allow me to do the same. In other words, some API that simply says, "DrawFrame". Finally, I also want to be able to resize the dialog/form. A MessageBox cannot be resized so I would obviously need to come up with a radically new solution. And while resizing, it cannot flicker. So my assumption here is that I will probably need to take a snapshot myself and handle the the moving/resizing. Has anyone done this before or at least know of an API that lets me take a snapshot of the entire screen (or just the form) ? Thank you Johann Tag: vb.net Tag: 87154

    - ObjectDisposedException without an ObjectName We have a program that has been in development for a number of years now, and it has created a fairly sizable startup routine that, on occasion, throws an ObjectDisposedException. We are logging the error, but it seems to occur at different places every time. In other words, it is difficult to debug. The main problem is that the ObjectName property of the ObjectDisposedException is always an empty string, as this VB.NET example: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Try Dim Test As New Button Test.Name = "ObjectTest" Test.Text = "Not yet disposed" Test.Dispose() System.GC.Collect() Test.Text = "This object is disposed" MessageBox.Show(Test.Text) Catch ObEx As ObjectDisposedException MessageBox.Show(ObEx.ObjectName) End Try End Sub This always throws the ObjectDisposedException, and the name is always a blank string. If the code is run in .NET full, then the ObjectName is "ObjectTest". Is this something we are doing wrong? Does anyone have any pointers as to a better way we can try to find this exception?

    - Simply obtaining the Mobile Phone Number of the User Hello all, I have written an application used by a large number of remote sales staff. When they sync their daily data, I want to know what phone number (SIM) they have in their smartphone. I have already used the TAPI to find the IMEI of the device. There seems to be quite a lot of information about how to find the phone number of the caller when a call comes in, but I'm just trying to find the phone number of the device itself. In other words, what you see in Start Menu : Settings : Personal (tab) : Phone : "Phone Number". Or, to put it a third way, if it was my mobile phone, what my own mobile phone number was. The application is written for an XDA II device, PocketPC version 4.2. In Visual Basic, compact framework. Any help appreciated! Thanks a lot in advance, as this is driving me nuts.

I don't really understand what you are trying to achieve. Parsing a text file
with floating point numbers? Can you show us some code?
