    - anyone used libpng with c#? I am desperately trying to save PNG image files from my C# CF application. I have found libpng for CE (lpngce at http://www.tenik.co.jp/~adachi/wince/lpngce/index.html) but not having a C++ backgroung I'm having some difficulty - at the moment I cannot even get it to compile. Has anyone else tried this or have any other way of saving PNG images? Stuart Tag: Playing Sound while on Call Tag: 77338

    - XmlEnum Name with Spaces It seems like XmlEnum marked values with whitespace in their names will not be deserialized on the .NET CF 2.0 E.g: public enum Foo { [XmlEnum("Some Value") Some, [XmlEnum("Another")] Other } I would expect: <element>Some Value</element> To deserialize into the enum Foo.Some. All of this seems to work on the Full Framework. Does anyone know what might be wrong with this? Thanks. Tag: Playing Sound while on Call Tag: 77334

    - XML over GPRS - Is this a good idea????? Hi All I was hoping some one could give me some guidance on the matter of sending data over GPRS. I have taken over an application written for Windows mobile 5.0 with VS2005. It is currently communicating with a web service via GPRS. The Web service places all the data into objects and then returns it to the PDA. And the same happens when sending stuff to the Web service from the PDA. My concern is the amount of Meta data(xml) that is being sent just to describe the Data itself. Is there a better way of doing this? Or do I have to live with it if I want to use OOP.

    - 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: Playing Sound while on Call Tag: 77299

    - 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: Playing Sound while on Call Tag: 77271

    - 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.

However, each time I deploy, it deploys it as a .NET 2.0 application. How can I programmatically check and change the version of the framework to use on the device. Basically I want to use v1.1. Any help would be appreciated. Thanks, Steve Tag: Playing Sound while on Call Tag: 77221

    - determine if pocket pc 2003 device has been disconnected from the network I currently have an app running on a pocket pc 2003 that connects to a webservice to update information. The device is using gprs for interconnectivity. In one particular module, data is sent to the server and waits on a feedback from the server. However, sometimes the gprs service is dropped and then the device hangs waiting on a response. The update is done in a try catch block but the device apparently gets no error indicating that the signal has been lost. How can I prevent the device from freezing when the signal is dropped? Is there a timeout setting I can set within my code that I can check to see if a response has failed to come in within that time? If so, how do I do this? I am using vb.net 2003.

    - 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? TIA Harry Tag: Playing Sound while on Call Tag: 77183

Can we play sound during call.
When i play a sound file, and there is an incoming call or outgoing
call, the player is paused.
Is it possible to play sound while answering the call ( talking on
