    - Memory Usage Hi All, I have a C# application that uses an SQL Server CE database and I am a little confused about the memory usage of my application. When I start the application the Control Panel -> Memory display shows that 7MB was consumed, but when I use the Performance Monitor (MSCOREE.STAT) it shows a Byte Allocation of 2 MB. This all came up because I have an h2200 that was showing Control panel memory usage of 2MB, and a h5500 that showed a memory usage of 7MB. I am confused. BTW. My DB is 3.5MB in size. Can anyone explain for me. Thanks, James. Tag: Event controles directory Tag: 38423

    - NetworkStream.BeginRead Blocking problem Hi all, I am trying to create CLient-Server based application. Talking of just Client application, I want to read data from the server application. For that I created a socket and a new thread that reads all the time from the server. However, the problem is when I close the socket (from client end), my data reader thread (created above) does not close down. In turn it keeps waiting for some message. After bit of struggle I noted that somehow BeginRead calls back the method after 1 minute. At that time my piece of code exits the thread. I want to close the BeginRead operation as soon as I close the socket. You help will be appreciated. For that purpose I am presenting you with the code that I have managed to write.

    - For Peter Foot Ok, additional to the PPC App installer, I made three modification to the PPC App setup project. 1. add a SQLCE.ini file: [CEAppManager] Version = 2.0 Component = SCE [SCE] Description = SQL Server CE 2.0 CabFiles = sqlce.wce4.armv4.CAB,sqlce.ppc3.arm.CAB,sqlce.wce4.armv4t.CAB,sqlce.wce4.mips16.CAB,sqlce.wce4.mipsii.CAB,sqlce.wce4.mipsii_fp.CAB,sqlce.wce4.mipsiv.CAB,sqlce.wce4.mipsiv_fp.CAB,sqlce.wce4.sh3.CAB,sqlce.wce4.sh4.CAB,sqlce.wce4.x86.CAB,netcf.core.ppc3.arm.cab,sql.ppc3.arm.CAB,sqlce.dev.ppc3.arm.CAB,netcf.all.wce4.armv4.cab,sql.wce4.armv4.CAB,sqlce.dev.wce4.armv4.CAB,netcf.all.wce4.armv4t.cab,sql.wce4.armv4t.CAB,sqlce.dev.wce4.armv4t.CAB 2. Add an invokation to the RunAppManager function as following Dim argSQLCE As String = Path.Combine(Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location), "SQLCE.ini") RunAppManager(argSQLCE) Dim arg As String = Path.Combine(Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location), "Setup.ini") RunAppManager(arg) 3. I add a "WaitForExit()" function after the process.start() function as following. Process.Start( _ String.Format("""{0}""", appManager), _ String.Format("""{0}""", arg)).WaitForExit() Then After I generate the msi file and run it, the PPC App can be installed, but when installing SQL CE it says "There is no device-compatible software to install. " I can send you my code if you don't mind. Thanks. Tag: Event controles directory Tag: 38421

    - Using multiple dataadapters does not work in CF??? Very odd behavior. I try to fill two dataadapters on the same connection and I get an exception on the 2nd fill.

    - Local datastore for visual basic .net aplication on a pda I have this project for developing an drug interaction aplication for a pda under a windows o.s . The aplication is being developed on visual basic .net (using visual studio .net 2003), and I needed to create an local datastore, the problem is that most of the database access controls and etc available on the full .net framework arenÂ´t available for the .net compact framework, so, so much for using an MS access database file, as for SQL, I kinda dislike the ideia of having to install the CE server on the pda just to run a lame database that only uses SELECT and WHERE (=?) queries (the aplication only reads a specific value from a field on the database and compares it to another value from another field). So after all this, here's my questions: Is there any way to use an sql database file as an local datastore without the SQL server running? Just by reading from the file that is? And how about an serialized xml file from the object model, could it do the trick or does it run in to the missing class prob in compact framework? Thanks for reading and for your time, help is most welcome. Tag: Event controles directory Tag: 38414

    - NullReferenceException on line that does nothing. Hi, I've got a strange NullReferenceException on this line: System.Data.DataTable oDT = null; I've tried not initializing it, and setting it to something on the next line, but that doesn't change anything. Strangely, it does not throw an exception when I'm running in debug mode (debugging on the device, not the emulator). It does throw when I deploy and run on that same device. Has anyone seen this behavior? Thanks, and have a good day. Tom Tag: Event controles directory Tag: 38409

    - Z-order top using SetWindowsPos "Peter Foot [MVP]" <feedback@no-spam.inthehand.com> wrote in message news:ul%23WSajxEHA.2676@TK2MSFTNGP12.phx.gbl... > You can use the technique described here to make your messagebox dialog > always appear at the top of the z-order until it is dismissed:- > http://blog.opennetcf.org/pfoot/#a11ad82c3-a428-4aac-959f-27c9c3590662 Peter, You say, this works until the form is "dismissed". How do you dismiss the form? I've converted the code you provided me with that for VB. I'm using a Me.Close to close my form. The first time the form appears, it stays up as I was hoping it would, not getting hidden behind other forms. But the second and beyond time it is called, its not going away, ever. I can tell that the form in the background is still running as I can touch buttons, at least the part of the buttons I can see behind my 'modal' form, and they work. Any ideas?

    - Detecting Open Forms Is there a way in CF .NET using C# to detect whether or not a form is already open in memory, and if so, using a conditional to show that form rather than having to do something like this: Form1 frm = new Form1(); frm.Show(); since that always creates another instance. I don't want users to have a bunch of the same form open on their PPC at one time, it's just silly and a needless waste of resources. Thanks Tag: Event controles directory Tag: 38379

    - Trouble with Multi Threading Hello All, I am in the middle of creating a class that I want to use with Serial IO per the MVP on this forum. I am still having trouble with my design process I think. I created a class that is designed to basically receive messages from the port. It is a CommEvent private void port_DataReceived() { byte[] data = port.Input; RxMESSAGE += Encoding.ASCII.GetString(data,0,data.Length); } this class is created from a WinCE form. there suggestion was to create a seperate thread that receives data. my question(s) in this process is 1)if I have a class that is created from a WinCE form( myThread = new Utility.myThreadClass(); ) with the event port_DataReceived. Will that event raise without locking up my WinCE form? 2) how do I start a thread that will allow this event to be raise and allow me to continue working on my WinCE form? In every other situation I have written a thread that calls one function, once that function was done the thread was done also, in this case I am trying to start a thread the allows an event to fire?

    - irda serial port emulator Hello, I am trying to write a program using .NET CF to interface with a PDA IR port which communicates with an ACTiSYS IR100S Intelligent IR port. This device contains the iRDA protocol stack so that when it is connected to a PC it looks like a standard RS232 port. I have some sample code which allows data to be sent via IrDA on my PDA. This works between 2 PDAs running the same software. If I try to connect to a PC then I would have expected to see some data when running hyperterminal. I do not. Also I have found a terminal emulator for the PDA which allows IrDA connection to the PC and I can send data from PDA to PC/ PC to PDA. Similarly I have tried my sample code talking between 2 PDAs where 1 has the terminal emulator and I don't see any data passed between the 2. The code I have will also discover IrDA devices and this works OK. I have 2 questions: 1. Why do I not see any data when running my sample code on either terminal emulator window? 2. Do you have any .net sample code which I can use to communicate between a PC and a PDA via IrDA? In my final application the remote device will be a "dumb" device which accepts commands via RS232, so I can not expect to be able to add any code to the remote device.

    - Serialization of arrays in dataset Hi, I have a dataset that I am using to transfer data to a web service from a device. One of the elements in the datatable contained within the dataset is a string array, which is stored fine in the dataset on the device. However, when the dataset is transferred and I try to retrieve the data from the array in the web service, the array is transformed into a string with the value "string.object[]" Now, I know that this is an effect caused by the serialization of the dataset during transport from the device to the web service, so what (if any) is the correct method of transferring arrays in datasets to web services?

    - Change specific treeview node font? Hi all, I would like to change only my "header nodes" font in my treeview. Is this possible? I used the following to try it: trvAppts.Font = New Font(trvAppts.Font.Name, trvAppts.Font.Size, FontStyle.Bold) But that set the whole treeview to Bold. I only want the header ones. Can the compact framework do this? Tag: Event controles directory Tag: 38282

    - Setup and Deployment Pocket PC Hi, I want to create a installation package for my pocket pc application. I have been to http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/netcfdeployment.asp to read through the article, but i still got problem Problem : I do not know how to create the 3 major Projects (CustomInstaler, Pre-Build and Setup) that mentioned in that article. I have cut and paste the paragraph to the following... "Two solutions are required for VB.NET. The first contains the Smart Device project called PocketApp. The second solution generates the .msi file and contains the projects CustomInstaller, Pre-Build and Setup. The CustomInstaller and Setup projects are equivalent to the C# projects and the Pre-Build project is a C++ Makefile project; it does not contain any C++ code and is only used to specify a pre-build event. The VB solutions are shown below." I hope someone could tell me how to create these 3 project, and allow me to create a installation package for my application.

    - Memory leaks or GC doesn't invoked? Hello all, I've written application that uses threads/timers and contains many different forms. I've noticed that if I left my application for the whole day then device show message that not enough memory. I'm not using calls of unmanaged code (I suppose so) but maybe it's the problem in the GC. Maybe I should force him to clean Gen0, Gen1 objects? Or maybe there is tips how can I detect memory leaks? Thank you, Tod Tag: Event controles directory Tag: 38268

    - Moving SQLCE from PPC2002 to PPC2003 We have a VB.NET application running on PPC2002 devices with a SQLCE database. The customer sets up any new devices by running the CF SP2 installer over activesync, and then copying over and clicking the SQLCE cab files (sqlce.dev.ppc3.arm.CAB and sqlce.ppc3.arm.CAB) However, the latest devices the customer has bought are PPC2003 devices, and when they attempt to install the above SQL files, they get a message to say they are incompatible with the system. Is is just a case of installing different SQL Files, or is there more to it? I have found a suggestion on another forum that the files; sqlce.dev.wce4.armv4.CAB and sqlce.wce4.armv4.CAB should be used, but the fact they have WCE rather than PPC in the filename makes me think they're for the CE.NET environment, rather than PPC. Can anyone shed any light on this? Thanks, Ian. Tag: Event controles directory Tag: 38261

    - Connect to server in emulator I'm establishing a connection to a sql server. When it runs on my handheld, the connection is established quickly (very fast). But when run under the emulator it takes a loooong time, the very first connection. It also errors out with 'server not found or access denied'. The second, third, etc time is very fast - so long as I don't wait too long between attempts (15 or so minutes). Strange thing too, the error I get is not true. I removed the try block as a test, and the connection failed (threw the message), but the attempt to use the connection further down in my code to access data proved fine. The connection was fine. Then why did it throw the error?? And whats happening that the connection takes about 15 minutes to establish (even tho it throws the error) the first attempt, but no time at all in successive attempts? ALSO, is there any way to cancel a connection while its attempting to open?? Thanks! Tag: Event controles directory Tag: 38251

    - ListView control hangs the application when filling up Hello everyone, I'm doing some tests with SQL CE and decided to use the ListView control to display data. The problem is the control hangs (freezes) the whole application if I, for instance, use the slidebar on it to scroll down a bit. Just to make sure this only happens with the ListView control, I created a button and clicked it numerous times, while the list was filling, and the application continued to respond fine. The device doesn't seem to be overutilised either, as I can smart-close the application fine (and start others) even after the ListView control makes the application stop responding. Could it be the fact that I have 40.000 records in my SQL database I am filling into the ListView control? Here's the code I'm using: ... ListViewItem lvi; System.Threading.Thread FillThread; ... private void button2_Click(object sender, System.EventArgs e) { FillThread = new System.Threading.Thread(new System.Threading.ThreadStart(FillThreadImpl)); FillThread.Start(); } ... private void FillThreadImpl() { try { SqlCeCommand oCmd = conn.CreateCommand(); oCmd.CommandText = "SELECT RTRIM(ProductName),RTRIM(ListPrice) FROM Produkti"; SqlCeDataReader oReader = oCmd.ExecuteReader(); while (oReader.Read()) { lvi = new ListViewItem(oReader.GetString(0)); lvi.SubItems.Add (oReader.GetString(1)); listView1.Items.Add(lvi); } MessageBox.Show("Done"); } catch (SqlCeException ex) { MessageBox.Show("SQL+ " + ex.Message); } catch (System.Exception ex) { MessageBox.Show("SYS: " + ex.Message); } } Any ideas what could be wrong? Thanks in advance, Amadej. Tag: Event controles directory Tag: 38250

Hi,

for my application I need an event wich controles a directory and fires, if
a file is added to the directory. Is something like this possible, and if
yes, how could I do that (I haven't wrote an event yet)?

Greets,

It sounds like you are after FileSystemWatcher functionality. This class is
not implemented in the CF but a quick search indicates that the openetcf
offers one:
http://groups.google.com/groups?hl=en&lr=&c2coff=1&q=FileSystemWatcher&meta=group%3Dmicrosoft.public.dotnet.framework.compactframework
