    - Mirrored forms - RTL for Arabic/Hebrew I'm trying to make some software that is Right-To-Left capable for use in Arabic and Hebrew. I'm running CE 6.0 and Compact Framework 2.0. The Window Layout and Mirroring page on MSDN makes it sound as though I can just call SetLayout and SetWindowLong and the whole form will mirror: http://msdn.microsoft.com/en-us/library/aa913269.aspx I can get the ControlBox and Form title text to flip to the other side (maximize button in top left), but that's about it. I was assuming all of the X,Y locations of the form controls would change when the origin moved. Shouldn't a button that is on the left of a form move to the right due to the Near / Far location? Am I missing something obvious? Tag: OpenNETCF.Desktop.Communication Question Tag: 89037

    - Problem with the Soft Input Panel (SIP) Hello, I have a problem with the "Soft Input Panel" (SIP). Please have a look at this screenshot of my application: http://img517.imageshack.us/img517/668/sipproblemzu9.png I have an own button to show the SIP. But if a click on this button, a second default button appears. Is it possible to deactivate the default SIP button? And a second question: How can I check, if the SIP is currently shown or hide?

    - Restarting message loop with new form after exception Hello, In my Main() method in Program.cs, I have an exception handler around my Application.Run(). If I catch an exception, I would like to bring up a dialog box asking the user if they would like to send an error report. In my first attempt, I created the form for the dialog box, then tried to restart the message loop with another call to Application.Run(). Unfortunately, this call to Appliction.Run() immediately throws an exception. The documentation says that this will happen if I try to start a message loop on a thread that is already running a message loop, and Application.Run() seems to think the message loop is still running. Perhaps this is because it was exited abnormally via an exception. In my second attempt, I starting a new thread, and called Application.Run() from there. This works, but adds a lot of clutter to an otherwise straightforward piece of code, and seems a bit kludgey besides. Is there a better way to do this? Thanks! ----Scott.

    - how to wait for data from the serial port Hi, I'm developing in c# .NetCF 2.0. I have two operations that need to come one after another(in fact there are more than two but the basic idea is the same). However, before starting the second, I must read and process the data from the serial port(which is generated as a result of the first operation). How to do it? What is the best way? What is the easiest way? Thank you very much Tag: OpenNETCF.Desktop.Communication Question Tag: 89029

    - gotfocus keeps firing I found the same issue, i had converted a vs2003 application to vs2005 and had textboxes which took advantage of the _gotfocus event to popup my own alphanumeric keyboard, this was all ok in vs2003. After converting, the same gotfocus would popup the keyboard as before but would keep firing it. After hours and hours of tinterweb meandering and general messing around, I removed the handles textbox.gotfocus entry and created AddHandlers for them instead Inside the gotfocus event i added a removehandler ( so it removed the callback ) Did the call to the alpha keyboard Then reapplied the addhandler. This seemed to fix it. Tag: OpenNETCF.Desktop.Communication Question Tag: 89028

I also created a Deployment Project and am now ready to create the cab files and distribute it. The application uses SQL CE and requires the Compact Framework to be installed on the Mobile device. I have all the cab files to install the SQL CE and Compact Framework. My question is how can I have on total installer that will install my project along with the SQL CE and Compact Framework? I am sending this to uses on the road and have about 6 different cab files that are required to be installed before the project can be installed and do not want the user to be bogged down install 6 different applications.

    - Help with custom 'clickable label' control I've created a basic clickable label derived from System.Windows.Forms.Control which works fine, BUT, I want to use it in a situation where it will be 'scrolled' around the screen and this is where it goes wrong, the 'OnPaint' event is not doing the background so it ends up being 'smeared' rather than cleanly displayed. Below is the 'OnPaint' code, what do I need to do to ensure it is 'cleanly' re-painted? protected override void OnPaint(PaintEventArgs pe) { Graphics gr = pe.Graphics; base.BackColor = ViewerColors.ViewerBackColor; if (Autosize) { SizeF size = gr.MeasureString(this.Text.ToUpper(), this.Font); this.Width = (int)size.Width; } else this.Width = this.Parent.Width - (this.Left + 4); Color textColor = ForeColor; SolidBrush b = new SolidBrush(textColor); gr.DrawString(Text, Font, b, 0, 0); b.Dispose(); } Chris Tag: OpenNETCF.Desktop.Communication Question Tag: 89003

    - Mobile Client Software Factory + VB.NET Example Hi Am am attempting to get the disconnected service agent withing the above factory working. I am using Microsoft Mobile Development Handbook Chapter 7 as my guide. I have setup the webservice and amended the config file and properties within the web reference to point to my service however the code is failing. on stepping the factory the problem is following the connection to the webservice the code attempts to call the Invoke within CommandCallback.cs This is found within Mobile Application Blocks\Mobile.DisconnectedAgent\CommandCallback.cs line 65 public virtual object Invoke(params object[] args) { object targetInstance = Activator.CreateInstance(targetType); MethodInfo method = targetType.GetMethod(targetMethodName); return method.Invoke(targetInstance, args); } The code errors at object targetInstance = Activator.CreateInstance(targetType); It would appear the targetype is set correctly? {Name = "OrderProductDialog" FullName = "DisconnectedServiceAgentExample.OrderProductDialog"} The error that is returned is MissingMethodException The C# version of the example works without errors but I need to get the VB example working, I have tried creating a new example but the same error is returned?

    - MouseDown event not firing after ContextMenu closing Hi, I have the (reproducible) problem that no MouseDown event is firing if I close a contextmenu by clicking besides it. I have a panel in which I do custom drawings, on some places there pops a contextmenu up and offers some options. If one clicks not on the menu, but somewhere else in die appliation the contextmenu closes (as expected) but the underlying panel does not fire any MouseDown event until it gets redrawed - strange is that MouseMove and MouseUp get still fired - unfortunately I need MouseDown and do not want to redraw the whole panel just because of the contextmenu closes without a click on one of the offered options (if one clicks on the context menu the effect also vanishes - then MouseDown is again there). Do you have any idea what this could be? thanks in advance, Tom Tag: OpenNETCF.Desktop.Communication Question Tag: 88998

    - Unit Testing classes using ResourceManager Hi, I am writing some unit tests for my windows mobile application.

    - Problem with DataTable.Rows.Select Hello In my Application i detected a strange, unexplainable behavior associated with DataSet and DataRow. In my DataSet i want to Select all rows with OrderState 1: DataRow[] rows = myDataSet.Tables["order"].Select("OrderState = 1"); Afterwards I write these orders to an XML to upload them to the Server. Within 6 months of beeing productive and hunderts of orders it happened 3 times that an order with OrderState 0 was uploaded. I cannot find the cause of this behaviour. The only ideas I have are: - The Select() method selected an wrong DataRow with OrderState 0 - The selected DataRow was correct but because of manipulating the DataSet from a second Thread (UI) the Pointer/Index of the DataRow changed and pointed to another Row with OrderState 0. This code runs in a background thread and the DataSet is bound to UI- Controls. The DataTable has a PrimaryKey-Column and NotNull-Constraint on OrderState-Column. Does anybody know how the internal relation between DataRow and DataTable is relized? Is it possible that a DataRow points to an index of the Table? So when I insert a new Row in the front, the DataRow points to an other row? Pleas tell me if you have an idea! Thanks Thomas Tag: OpenNETCF.Desktop.Communication Question Tag: 88961

    - IOCTL_HAL_GET_DEVICEID not returning a unique ID :( I've been using a call to IOCTL_HAL_GET_DEVICEID in a VB.NET project to return the unique 2 part device ID of a PDA and it's been behaving fine on many different devices, however, we've recently got some iPAQ 214 PDAs in and all of a sudden the code is returning exactly the same ID for each iPAQ 214 we run it on... It's fine on other iPAQ's and all other brands we've used seem fine, it's just the iPAQ 214's.... I've seen a million forum questions with people asking how to get a unique ID from a PDA and all the answers seem to be to do it the way I'm doing it using KernelIoControl and IOCTL_HAL_GET_DEVICEID... So why isn't it working in this one specific case? Any ideas anyone? Thanks, Paul Tag: OpenNETCF.Desktop.Communication Question Tag: 88938

    - Tips on using .NET events from a background thread Hello, I've posted a few questions here in the past about using events which are fired to a background task. I've taken what I learned, here and through experimenting and tracking down bugs, and summarized it on my Web site. I'm hoping this will be useful for others here who may be dealing with similar issues, and also to get feedback, which I will use to update the page and also to improve my own code. The page is here: http://www.suspectclass.com/~sgifford/tips/dotnet/DotNetAsyncEventTips.htm Here is the introduction from the Web page. Please contact me if you have any feedback, find any mistakes, etc. You can email me directly, or if it's relevant to the group just post here. Thanks! ---Scott. Tips on using .NET asynchronous events from a background thread Our .NET client quite a few asynchronous events called from background threads. We use a LargeIntervalTimer to drive events and we have a network client which receives updates asynchronously over the network, similar to Pocket Outlook's Always Up To Date. Besides those, if we do something that may block for awhile, we send it off to a background thread and have it fire events to notify us of its progress. After working on this for awhile, we have learned (often the hard way) that there are a few tricky things with firing events from a background thread. The first is that they aren't running in the GUI thread, so you will have to use Invoke/BeginInvoke to interact with the GUI. A trickier problem is that they can fire at inconvenient times, such as after a component has been disposed, or while it is disposing. This page has some tips on dealing with all of the issues we have encountered so far. Tag: OpenNETCF.Desktop.Communication Question Tag: 88913

    - Problem with dialogs May be the problem comes only from my misunderstanding of how to use forms for dialogs. I want to have a dialog I can accept or cancel. And I want to do some validating on the form level. I know in WM there is only the "OK" on the upper right corner. So I have to put two buttons "Accept" and "Cancel" on the form. May be here is the first mistake I make, I decided to have two menu items for accept and cancel. Here are the problems I have. I use databinding to bind the control properties to some form properties. Closing the form by pressing the OK-Button doesn't free the focus from the current selected control, so databinding doesn't work. Focus the form in Closing event, as someone suggested, also doesn't help. The only way I found is to call the controls BindingManagerBase.EndCurrentEdit(). Is there e better way? Next, pressing the OK-Button fires the Closing event and I can do form validation. But closing the form from the menu items by calling the Close method of the form, fires the Closing event twice. Is the another way to close the dialog form than by calling the Close method? The last problems comes with the previous. As I found out that the Closing event is fired twice, I tried to skip one, because I want to bring up a MessageBox while validating, which shouldn't be shown twice. In case of prevent from closing I have to set the event handler argument to Cancel. But it doesn't matter if I do this for the first or second call of the Closing event, I have to do this for both. Only in this case it works. All these problems makes it very difficult to have an assumed dialog behaviour. So I assume I'm doing something wrong. Can someone point me to ma mistakes?

    - SQLCE db sync with Windows Mobile I am writing a sample app to learn Windows Mobile development. I have been able to get the app working in the emulator but now would like to sync the data so it does not get reset on the next deployment to the mobile device. So, does anyone know of a tutorial that explains how this is done? Also, if there is a better group to post this message to, let me know as well. Thanks, Steve Tag: OpenNETCF.Desktop.Communication Question Tag: 88865

    - DB Corruption Due to memory issues, I recently changed my application to open,close and dispose the db connection on the "fly" rather than using a shared connection. According to the article in the link below, this is recommended. Now that I have done this, A lot of my devices in the field are getting corrupted databases. Has anyone else ran into this or am I better off going back to a shared connection?

    - .NET CF / ActiveX / COM Confusion! Hi all, I'd be really grateful if anyone could help clear up a point of confusion reagrding the .NET Compact Framework, supported languages, and the use of COM & ActiveX controls. We have a PocketPC app, currently written in eMbedded Visual C++ 4.0, which depends heavily on a set of COM Dlls and an ActiveX control (which provides a graphical 'map window'). We would like to rewrite this as a .NET Compact Framework type App, to take advantage of features such as easy loclisation etc. However, as I understand it, we cannot have a .NET CF app (in any language), that also uses COM and Active X controls in it - is that correct? Also, the only two .NET CF languages are C# and VB, and there's no managed C++ extensions for the CF - is that right? Thanks for any help you may be able to provide, Tony.

    - Losing MouseUp Events Hi, I have a user control that is not receiving MouseUp events intermittently. The control itself handles MouseDown, MouseMove and performs some drawing on these events. The problem seems to manifest after performing a fast move (a flick) with the stylus and releasing the stylus at the end of the flick, the stylus is most definitely over the control when the mouse up occurs too. I'm not too familiar with how .NET processes events, could it be possible that the MouseUp event is being dropped due to too many MouseMove events being in the queue before it? The platform is Windows CE 5.0 and I'm using .NET CF 2.0 Thanks in advance for any help. Tag: OpenNETCF.Desktop.Communication Question Tag: 88852

    - Vertical Sync Hi, Currently I am developing for Windows CE 5.0 using .NET CF 2.0. I have a custom control that displays a subset of a long (vertically) bitmap. The user is able to touch their stylus on this bitmap and drag up / down to visually drag the image up / down so they can explore the length of the image. The problem is that as the image redraws onto the screen during a scroll, a degree of visual tearing occurs and its quite visually distracting. Is there anyway to counteract this? (Ie enabling VSync or equivalent using .NET or is this something that should be done via the graphics driver?) The drawing is done by overriding the OnPaint base method of the control class and using the Graphics DrawImage function. I'm quite new to .NET graphics so apologies in advance if I'm missing anything glaringly obvious. Tag: OpenNETCF.Desktop.Communication Question Tag: 88851

    - Using WZCEnumInterfaces using interop in C# Hi, I am trying to use the native WinCE API WZCEnumInterfaces using interop in C# .NET compact framework. I have to develop this without the OpenNetCF wrapper. But whenever I call the function, I get the exception "System.NotSupportedException". I looked at the help page for this exception and I think I have taken care of all the possible causes for the exception. Could anyone please let me know anything that I could be doing wrong.

Hi, can anybody guide me in how to use the OpenNETCF.Desktop.Communication

I don't think the library gives the ability to pull back a list of running
processes. I think you would have to launch an application on the device
which checks whether a process is running (e.g. using ToolHelp APIs) and
have some method to communicate this back to the desktop (write to the
registry, file, socket etc).

If you're comfortable with C, you can write a RAPI extension method and
use OpenNETCF.Desktop.Communications.RAPI.Invoke to execute the method.
The method should enumerate the processes on the device using the
ToolHelp API. It's relatively straightforward to do.
