    - 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?

    - Best choice of data storage on PDA in C# (short term/ long term) I am a newbie, so please be patient. I am working on an app that will extract data from an embedded system via serial connection. I need to get the data as fast as possible and then go back and assimilate it after I've disconnected. What is the best way to store this data for both the temporary and long term?

    - 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: Can I directly access hardware using managed code?

    - 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?

However, when I add my control to the toolbox it appears disabled. I understand that something is wrong but I cannot figure out what it is. Is there any way to get more information on what is going on? Do you know of any descent tutorials on control develpment (because MSDN's documentation on this topic sucks!). Thanks in advance!

    - 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.

I can properly install the the PPC application, but the SQL CE is not able to be installed properly. Can anybody send me a sample setup project in VB.NET(coz my PPC application is in VB.NET)? My email is: fengcs@ccdynasty.com It's really urgent. Many thanks. 2. I am given this message every time I install the PPC application. The message says that:" the program is not properly installed as it's for the previous version..." However it seems the program is running smoothly after installation.

    - 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?

    - Threading & Synchronization in CF 2.0 Hi, Has the CF 2.0 more support for inter-thread synchronization ? For example, the absence of Monitor.Wait and Pulse methods in 1.0 are a bit of a pain (OpenNETCF partially solves this). The reason why I am asking is that the documentation in VS 2005 mentions .NET CF as a supported platform for some of these methods. Monitor.Wait Method (Object) ... Target Platforms: <...> .NET Compact Framework But the methods do not seem to be available (Intellisense does not find them). Documentation typo ?

    - How do I unload a Smartphone app via the Compact Framework Hello all, In order to programmatically uninstall an app via the Compact Framework, one just calls "\Windows\unload.exe", "appname.exe" on the Pocket PC.

    - Issue with Icon constructor in CF SP2 Hi All, This seems to be a new bug that has been introduced in CF SP2. I now get a 'NotSupportedException' when using the Icon constructor that takes a Stream. If I do not install SP2 the constructor works fine (using PPC 2003 Phone Ed emulator). Here is the C# code that is used. Stream stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("FMRS.Images.icon_first.ico"); Icon icon = new Icon(stream); //this blows up with SP2 imgListReading.Images.Add(icon); As I said, the code works fine without CF SP2 installed. I have checked that the stream is not null. This is the error I get... *** An unhandled exception of type 'System.NotSupportedException' occurred in System.Drawing.dll Additional information: NotSupportedException *** There is no message with the error, nor an inner exception, which is especially nice!

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.

    - 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.

    - 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: Can I directly access hardware using managed code? 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?

Never to be found again by a user unless I get called and look at Start | Settings | System | Memory | Running Programs. Its running, but not displaying on top. I can't seem to recreate it so I can continuously duplicate it. I know the code below may not be much help, but maybe??

I am trying to invoke CeFindAllFiles from within Visual Basic, and I have defined the pInvoke interface as <DllImport(DllName, CharSet:=CharSet.Unicode)> _ Public Shared Function CeFindAllFiles( _ ByVal szPath As String _ , ByVal dwFlags As FAF _ , ByRef lpdwFoundCount As Integer _ , ByRef ppFindDataArray As IntPtr _ ) As Integer End Function I have also defined the CE_FIND_DATA structure as <StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Unicode, Pack:=4)> _ Public Structure CE_FIND_DATA Public dwFileAttributes As Integer Public ftCreationTime As FILETIME Public ftLastAccessTime As FILETIME Public ftLastWriteTime As FILETIME Public nFileSizeHigh As Integer Public nFileSizeLow As Integer Public dwOID As Integer <MarshalAs(UnmanagedType.ByValTStr, SizeConst:=MAX_PATH)> _ Public cFileName As String End Structure BUT...I have no idea how to set up a VB data element as 'ByRef ppFindDataArray As IntPtr' so that I can define the call to CeFindAllFiles in VB and get back data that I can actually access..Can some C++/VB genius out there give me a hint here? hopefully Glyn J Meek Tag: Can I directly access hardware using managed code?

    - Text in Combobox Hi All, I am having trouble putting text in the combobox in a pocket pc app in .net. I can populate the drop down list but I also want text in the combobox (before an item has been selected), I could do this in eVB with: CboMachine Number.Text = "105763" This would be displayed in the combobox. It doesn't seem to work in .net, my combobox is always blank until an item is selected from the combobox list by the user, any idea's. Thanks in advance for your help. Roger.

    - Button Toggle Is there any way to make a button toggle like effect in CF .NET? I'm trying to achieve the same look as a Palm in the sense that you can have buttons (actually radio buttons) that can stay selected, or in the down position until another button in the same group is selected, then the original ones pops up and the newly selected button stays down.

    - Detect Storage Card Root Folder Name I am writing an application in C# and I was wondering if there is a way to detect the name of the storage card folder, specifically if its name is "SDMMC Disk" or "Storage Card" this way I can grab that folder name no matter what it is and use it in another string to locate a file on the Storage Card.
