    - optimizing for JIT and generics, possible bug/issue? We've noticed in our project that adding a reference to a new Dictionary<> type adds about 600ms to the JIT time of a class. For example, class A has a private member variable: private Dictionary<string,CustomClass> _var; When assembly.CreateInstance() is called for class A, it is 600ms slower WITH the reference to Dictionary than without. Is this a known issue, and are there any better workarounds than making my own typed dictionary class? Tag: Encrypting and storing data in registry. Examples? Tag: 77299

This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small.

    - Howto fill a sql mobile database with a dataset filled with readxml Hi All, On the desktop I have multiple SQL server 2005 Express edition tables. On the server, I use a dataset in combination with writexml to generate an xml file (dnldata.xml) from a couple of queries (DnlData.WriteXml("c:\test\Dnldata.xml")) After it, I transfer dnldata.xml to the pda and use ReadXml to fill a DataSet. What is the easiest (best) way to read the dnldata.xml into an SQL MOBILE 2005 database (*.sdf)? The old fashioned way was using csv files with records, mannually inserted into the pda database. I want to change that. The structure of the SQL server 2005 Express edition tables and the SQL MOBILE 2005 tables on the pda are exactly the same. Do I have to parse all the records manually? Or Can I use Dataset.readxml in combination with other data-objects? probably this is not the right way. Any help would be greatly appreciated. best regards I tried the following which not seems to work: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim DnlData As New System.Data.DataSet Using MySqlConnection As New System.Data.SqlServerCe.SqlCeConnection( _ "Data source=" & "\Storage Card\Ztest\Mydb.sdf" & "; " & _ "SSCE:Database Password=xxx; " & _ "SSCE:Encrypt Database=True") Using MySqlCeDataAdapter As New System.Data.SqlServerCe.SqlCeDataAdapter("Select * from klant", MySqlConnection) Dim MySqlCeCommandBuilder As New System.Data.SqlServerCe.SqlCeCommandBuilder(MySqlCeDataAdapter) MySqlConnection.Open() DnlData.ReadXml("\Storage Card\Ztest\Dnldata.xml") MySqlCeDataAdapter.InsertCommand = MySqlCeCommandBuilder.GetInsertCommand MySqlCeDataAdapter.UpdateCommand = MySqlCeCommandBuilder.GetUpdateCommand MySqlCeDataAdapter.DeleteCommand = MySqlCeCommandBuilder.GetDeleteCommand ' MySqlCeDataAdapter.Update(DnlData) ' End Using End Using End Sub Tag: Encrypting and storing data in registry.

    - PPC Synchronization I need to sync my pocket pc to a server. I'm thinking of using "funambol." Has anyone tried using it? And one more thing, if I'm going to synchronize PPC to a server, may it be through funambol or active sync, will my keys and ID's change in the server? And if ever it would change, how would I get or retrieve the mappings of the ID's of items (such as tasks, calendars,account, etc...)? I need it to make the my PPC application consistent and working in the server. Thanks! Tag: Encrypting and storing data in registry. Examples? Tag: 77270

    - Exporting images to XML I'm writing an application that holds a signature image in a SQLCE database. I need to export this image to an XML file. I have tried this (in C#) with DataSet.WriteXML(filename) and it works fine; the resulting image seems to be compressed (a little under half the original size) and is human-readable (no weird unprintable characters). However, I am parsing all the records and exporting only the fields I need. I have two questions: 1) Is there a way to tell WriteXML() which fields I want to export? 2) How can I compress/write the image data the same way as WriteXML()?

    - z-order with DX and CF Hi, I have the following problem with DirectX (CF) that I'm still trying to figure out... The thing is that I need to draw a lot of (dynamic) sprites, but I was used to (in other languages) the fact that the latter sprites you draw are placed in front of the others.. This is not the case of DXCF, since (I'm guessing for optimization reasons) the order in which you draw the sprites is not related to the order in which they will appear in the screen... So, is there someway to change the z-index ?(meaning the index of a sprite in the z-buffer)...any thoughts/walkarounds?? Or maybe a way of forcing that the order you draw the sprites is the same that the order they will appear?? (even if this implies a performance drop down) Thanks you very much in advance. Miguel.

    - Help? I've posted something very similar to this in the SQLServer CE area but but just am not getting any response over there so I figured I'd tap the brain trust over here! Recently ported my VB.NET PPC app to VS2005. Also replaced my database (SQL Server 2000) with the SQL Server 2005. I knew I'd probably have to install a new server agent for the SQLserver2005 database to still be able to RDA Pull from it. Welp I tried and did not succeed in pulling using the new syntax (really I just changed the agent dll name that was in the newly created IIS virtual directory SSCE30.) Did any of the calling code change? With rda .InternetLogin = String.Empty .InternetPassword = String.Empty .InternetUrl = _strInternetURL .LocalConnectionString = g_strlocalDataSource .Pull("Users", strSQL, _strRemoteConnect, System.Data.SqlServerCe.RdaTrackOption.TrackingOff) End With Anyway I went back to the old SSCE20 pointer and THAT actually works with the new SQLServer 2005 database!! Weird eh? My general question is this: Apparently in debug run mode via ActiveSync, it IS possible to use the old agent DLL sscesa20.dll to Pull data from a SQLServer 2005 database. I've not been able to do this from the ethernet cradled device running the same code. If my app might be paired with either Windows 2000 SP3 OR SQLServer 2005, must I right different code to branch to the appropriate agent? or is there an agent that I should use that is compatible backwardly?

    - Emulator Shared Folder problem Hi, I'm using the PPC 2003 emulator with C#2005, Sql Mobile 2005 to test my application. I have a storage card emulated which is part of my c:\ drive and has a sql ce database on it. When I try to insert records, the record is inserted (Affected records : 1) and removed right away. No errormessage is returned. Everything works fine when I move the database to the emulator instead of the storage card. Does anybody know why this happens ? I found someone that has the same problem, so I'm sure it has something to do with the shared folder on the emulator, but no solution or explanation.

    - C# IntPtr with moved memory location, how to apply 'fixed'? Hi, i have an unmanaged C dll and i call a function from C# which returns a pointer on a struct inside the C dll: // C# code: //member variable IntPtr intPtr; someMethod() { intPtr = getStruct(); // calls C dll } when i later use the intPtr (passing it to C dll) it seems to point to another memory location. I have tried something like fixed (void *p = intPtr.ToPointer()) { ... } but this does not compile: "You cannot use the fixed statement to take the address of an already fixed expression" How can i fix my memory location?

    - RDA Pull SQL Server versions I've posted something very similar to this in the SQLServer CE area but but just am not getting any response over there so I figured I'd tap the brain trust over here! Recently ported my VB.NET PPC app to VS2005. Also replaced my database (SQL Server 2000) with the SQL Server 2005. I knew I'd probably have to install a new server agent for the SQLserver2005 database to still be able to RDA Pull from it. Welp I tried and did not succeed in pulling using the new syntax (really I just changed the agent dll name that was in the newly created IIS virtual directory SSCE30.) Did any of the calling code change? With rda .InternetLogin = String.Empty .InternetPassword = String.Empty .InternetUrl = _strInternetURL .LocalConnectionString = g_strlocalDataSource .Pull("Users", strSQL, _strRemoteConnect, System.Data.SqlServerCe.RdaTrackOption.TrackingOff) End With Anyway I went back to the old SSCE20 pointer and THAT actually works with the new SQLServer 2005 database!! Weird eh? My general question is this: Apparently in debug run mode via ActiveSync, it IS possible to use the old agent DLL sscesa20.dll to Pull data from a SQLServer 2005 database. I've not been able to do this from the ethernet cradled device running the same code. If my app might be paired with either Windows 2000 SP3 OR SQLServer 2005, must I right different code to branch to the appropriate agent? or is there an agent that I should use that is compatible backwardly?

    - Prevent light-off/key-lock/suspend/standby My application has to upload quite some data, which takes a long time. In the meantime the device goes into 'suspend' mode (at least the light turns off and the keypad gets locked). The side-effect is that the network connection is broken as well (at least the WiFi connection). How to prevent 'suspend' can be found here: http://msdn2.microsoft.com/en-us/library/z4k4wb9k(VS.80).aspx But that didn't solve my problem.

    - KeyPreview? Hi, We are developing a WinCE app for PocketPC 2003 (.net 2). I am using KeyPreview = True in my forms to be able catch some keys and do special processing in the forms (like shortcuts). We have a main menu form that uses those shortcuts to call other forms. If we have keypreview = true in the children forms when they are activated the KeyUp event is called in the form (like the key was pressed for them, ie: like pressing the key twice). Any ideas?

    - CE 5.0 Video and Animation I've searched this and other groups and haven't come up with an acceptable solution. We need to be able to display animated gifs and video (avi,wmv,mov... any single format will be fine) within a control on a form. We have Windows CE 5.0 platform with windows media player 9. It is not pocket pc or windows mobile. 1. For the gifs, I've looked at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/animationcontrol.asp and don't want to have to convert all of our gifs to this storyboard format. Actually I don't know of a program that will do this for me. Has anyone found a solution for this? 2. For the video, I understand that for WMP 10, I could build an activex wrapper and use the activex version of WMP, but we currently do not have WMP 10 available and I'm not sure if our supplier would be able to add it to our devices. Has anyone found/developed a non-wmp solution for diplaying video within the compactframework? or are there other 3rd party solutions available that I'm not finding?

    - Windows mobile form layout question (hiding/unhiding controls) Hi, I am developing a wireless survey application. This application could have three sets of controls: Radio buttons or Checkboxes and a text area. A question could "select only one" in which case I will show the radio buttons and a textarea for any comments. A question could be "select all that apply" in which I will show the checkboxes and a textarea for any comments. And a question could be "open-ended" in which case I will show just the textarea for comments. Now, I know that I can of course hide the control by setting the visible property of the checkboxes. However, for open-ended questions, I want the text area to move up where checkboxes and radio buttons would have been so there is no break between where the question ends, and the text area. If I just hide the radiobuttons/checkboxes, their place is still designated on a windows form. How can I actually move the textarea up to take up the hidden radio buttons and checkboxes space? Thanks. AIK Tag: Encrypting and storing data in registry. Examples? Tag: 77156

    - Callback function pointer on CF 2.0 from unmanaged C DLL -> NotSupportedException Hi, i'm not sure if this is a bug in the CF2, so here are the details: I have One Windows Mobile CE 5.1.195 (IPAQ hw6910) One Windows CE 4.2 PDA with Arm XScale (Psion Teklogix) On both i have installed compact framework .net 2.0 SP1 (cgacutil.exe shows 1.0.4292.2 and 2.0.6129) I have compiled the C# exe and C dll code with VC++ 2005. When i want to call a native unmanaged C dll with a callback function pointer i get: ---------- NotSupportedException: System.Runtime.InteropServices.Marshal.GetFunctionPointerForDelegateInternal ---------- During startup my System.Environment.Version.ToString() reports CF 2.0.6129 Here is the code: // C# public delegate bool FPtr(int value); public class LibWrap { [DllImport("test.dll")] public static extern void TestCallBack(IntPtr cb, int value); } public static bool DoSomething( int value ) { Console.WriteLine( "\n[C#]: Callback called: {0}", value ); return true; } And i call it like this: // C# FPtr cb = new FPtr(DoSomething); IntPtr cbForDelegate = Marshal.GetFunctionPointerForDelegate(cb); LibWrap.TestCallBack(cbForDelegate, 99); // throws exception! The C test.dll header: extern "C" { typedef bool (CALLBACK *FPTR)( int i ); __declspec (dllexport) extern void TestCallBack( FPTR pf, int value ); } The C test.dll source: extern "C" void TestCallBack( FPTR pf, int value ) { bool res; printf( "\ndll: Received value: %i", value ); printf( "\ndll: Passing to callback..." ); res = (*pf)(value); if( res ) printf( "dll: Callback returned true.\n" ); else printf( "dll: Callback returned false.\n" ); } I have tried to compile the dll with /TC or /TP (c++), same result.

    - Sending Windows msgs: C# to C++ First off, thanks to everyone in all groups for helping in the past. I'm developing an application that is a mixture of two types of executables: the "parent" file is written in C# and the "child" is written in C++. I need to have some basic communication from the parent to the child. I've looked into calling SendMessage and PostMessage, but I just can't seem to find exactly what I'm looking for. And, unfortunately (as usual), I need to have it yesterday. Here's what I'm trying to do. The child app is started automatically upon a reboot of the device. Then, the parent app is started. The child app is a specialized communication system that, at this point, must be written in C++ (using eVC4). The parent app (written in VCS2003) contains a button ([File Transfer]) that packages the data in an XML file and adds it to a "queue". Then, it starts the comm process (child app) if it isn't already running. All of this takes place when the device is docked in a special cradle. I need to be able to: 1) Get the "application" handle of the child, if it exists; or create the process and get the handle (starting a child app seems to work with no problem). The message functions require an HWND, which I believe is the same as an IntPtr, but I'm unable to properly convert/use it. 2) Send a message to the child app to tell it to minimize or maximize. In other words, I want it to "sleep" in the background until it's needed, and then become visible. Caveats: I am doing this with Windows CE Pocket PC version 4.20. I'm also using CF 1.0. I also have OpenNETCF 1.4 available. I can't seem to get CF 2.0 to work on this hardware/OS. Can someone...anyone...explain to me how this is done, or point me to a resource?

    - MSMQ HTTP queues in Windows Mobile 5 Hi. Not sure if this should be in this group or the msmq group. We are developing a windows mobile 5 application using VB.NET CF2.0, VS2005, that is to send messages using MSMQ to a client server. the client will only accept this if we connect using HTTP queues. I've seen postings & weblogs relating to this which initially said HTTP wasnt supported in MSMQ in WM5, then it was but there was was a bug in it. I've not seen any subsequent postings to indicate if the bug is fixed. Can someone please point me in the right direction to an answer? Thanks. Ian. Tag: Encrypting and storing data in registry.
