After installing the latest greatest form Symbol I can no longer run my application in debug mode. It gets to the splash screen and before it can get to the main screen a error occurs: "A native exception has occurred in EasyIDMobile.exe.

    - Visually inheriting from abstract/generic UserControls in CF Hello, I'm using Visual Studio 2008 Beta 2 and .NET Compact Framework 2.0. I have a UserControl component for editing rules. Right now I'm using a class which inherits from UserControl and uses a generic type to hold the type of rule that is being edited. Then derived types specify the generic type to say what type of rule they can edit. I like this design because it lets me put some common code in the parent class, and if I try to pass the wrong sort of rule to a UI component I find out at compile-time. Roughly it looks like this: public abstract class Rule { ... } public abstract class GenericRuleControl<T> : UserControl where T : Rule { public abstract void SetRule(T rule); public abstract T GetRule(); // Common code for all inherited types } public class TimeRule : Rule { ... } public class TimeRuleControl : GenericRuleControl<TimeRule> { // ... } I coded this all up and it worked great. Unfortunately the first time I closed and re-opened the project in Visual Studio it stopped working. I found out this is because abstract or generic base classes aren't supported in the designer. I managed to find some instructions for making it work, here: http://www.urbanpotato.net/default.aspx/document/2001 That code works fine in a desktop project, but in a Compact Framework project I get these errors: Error 2 - The type or namespace name 'TypeDescriptionProvider' could not be found (are you missing a using directive or an assembly reference?) Error 5 - The type or namespace name 'TypeDescriptionProviderAttribute' could not be found (are you missing a using directive or an assembly reference?) And indeed, the documentation for TypeDescriptionProvider says that it is not supported on the Compact Framework. Does anybody have any suggestions for making this work in the Compact Framework, or doing something roughly equivalent? Thanks! ----Scott.

    - Multiple PictureBoxes in User Control Problem I've created a user control that contains multiple PictureBox controls. I only want to display text within these controls so I've overriden Paint and do a DrawString. All PictureBoxes on the user control point to the same Paint function. The problem is that only the first control displayed actually displays anything despite Paint being called for each control. The rest of the controls are all blank. No errors are thrown so I have no idea whats happening. Below is the code for the User Control public partial class ucPB : UserControl { public ucPB() { InitializeComponent(); } private void pictureBox1_Paint(object sender, PaintEventArgs e) { PictureBox pb = (PictureBox)sender; string display = pb.Name.Substring(1); Font f = new Font("Verdana",8,FontStyle.Bold); RectangleF rf = new RectangleF(pb.Location.X,pb.Location.Y,pb.Width,pb.Height); SolidBrush sb = new SolidBrush(Color.Red); e.Graphics.DrawString(display, f, sb, rf); f.Dispose(); sb.Dispose(); } } Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86452

    - Deploying cab files Hi, I have developed an app in CF 1 and created cab files. There are 6 cab files, obviously for different devices. How should I deploy these? Do I just copy the relevant cab file to the device then run it or do I need to create some kind of installer. Apart from looking at my device, how would the general user know which cab file to install? Do I install actually on the device or do I run the installer on the PC and it installs to the device? If I can do it from the PC, is there anyway to automate it? (i.e. my app is a cut down version of a desktop version, I would prefer that somehow, the desktop version would manage the PDA version.)

    - SQL compact or XML? Hi, I am developing an application that requires storing of data, i first started out with using XML and DataSet as my dbase but i figured out i need to run several quiries and return certain data set, which can't be done using XML and that the data might get big by time and loading the whole file in memory will cz problems especially performace. So i decided to try out SQL compact. Here's my problem, if i am using SQL 3.5 to develop my app does my users have to deploy it on their devices, or can i just add the DLL files to my project (or cab file) and would work?

    - wceload exit codes Hi, Does anyone know of a reference for wceload exit codes? I've searched for it and saw other people searching for it, but it hasn't been found yet :). Or, if anyone knows what exit code 00004005 means, that would also be great. I'm trying to install some cab files using Pocket PC Installer on a Korean WM6 device and this is the result: Running: \Windows\wceload.exe "\Temp\PPCInstaller\System_SR_ENU_wm.cab" /delete 0 ok, exit code: 00004005. Running: \Windows\wceload.exe "\Temp\PPCInstaller\Setup.CAB" /delete 0 ok, exit code: 00004005. So it happens for a standard Microsoft cab file and for my own setup.cab file. The strange thing is that when I manually install the cab files, so not using the Pocket PC Installer tool, it works fine.

    - Embed form into another using SetParent Hi! I'm trying to make one form the child of another using SetParent. I tried CF1.1 on CE4.2 and CF2.0 on CE6.0 but without success. What do I have to do to make a form a child window? On XP I can take two visible forms and call SetParent. I think this is not possible on CE. What are the limitations? I could not find a code sample by now demonstrating SetParent with CF. Is it actually possible with CE?

    - Imaging and DPI I'm working on a project where I need to be able to adjust the DPI of either a Bitmap, Image, or Graphics object. So far I can't find anything that will get it off of the standard 96 DPI. Surely there's a way to modify one of these objects to different DPIs (something like the full framework's Bitmap.SetResolution() method). Am I just missing it?

    - DLL,MFC,Bitmaps Hi, I have an MFC DLL that reads a file and generates a bitmap which I then need to display in my C# app. This is a CF 1.0 app (so no Graphics.GetDC method unless I use GraphicsEx). I have two plans: Plan A: The C# app passes in the file name and some other parameters to the DLL. Then the app gets the image's width and height from the DLL and (in the C# world) does a new Bitmap (w, h). The app then passes this bitmap back to the DLL and the DLL draws into it. This way, the Bitmap's memory management is done in C# and the DLL is only used to draw into the bitmap, not to create/dispose the bitmap. Plan B: The C# all passes in the filename and some other parameters to the DLL and gets back a bitmap. The DLL would create/dispose the bitmap. Please let me know what you think of these two approaches (or if there is a third). Also, if you can help with the PInvoke stuff that would be appreciated. I read that I can pass a C# Graphics object in as a CDC pointer, but that doesn't seem to work. Also, what would be the cherry on top is if I could force the image to an indexed image to save memory. Any ideas, comments, URLs, example code very very very much appreciated. Thanks, Hilton Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86421

    - How do I Gradient Fill A Polygon the Compact Framework way? Help! I need to gradient fill a Polygon on a Windows CE 5.0 system. How do I do it? This works beautifully on a Windows Vista desktop as the target: //******************************* GraphicsPath pathPoints; // fill the points path (for example a rounded rectangle) Brush brushButton = new LinearGradientBrush(rectDraw, colorTop, colorBottom, LinearGradientMode.Vertical); e.Graphics.FillPath(brushButton, pathPoints); //******************************* However I need to run my app on a CE 5.0 (.NET) system. I've made the shape into a Polygon since the Compact Framework doesn't have a "GraphicsPath" - however, I really want to fill the polygon with a gradient. //******************************* Point[] pointArray; // fill the point array with (for example) a manually generated rounded rectangle Brush brushFill = new SolidBrush(Color.Blue); // I want this to be a gradien not solid!!!! e.Graphics.FillPolygon(brushFill, pointArray); //******************************** Microsoft shows how to fill a rectangle: http://msdn2.microsoft.com/en-us/library/ms229655.aspx but not a polygon.

    - Using window panels instead of windows.forms Hello .Net enthusiasts. I have a problem with a Mobil Application I'm developing on the Windows CE 5 platform. The application will crash eratically without displaying debugging info usually when loading a separate form using show and hide methods. I placed try/catches on all the code blocks I thought would contribute to the crash, but have not solved the problem. I've been reading forums and have come to the conclusion that the entire application should be using one form and multiple windowing panels instead of loading a new form every time. Could this be the problem, or is mine rooted much deeper? I really would like to figure this out, so any insight would help. If I should move all the forms into panels, what would be the best way to go about this as each form is in a separate file. Thank you for reading. P.S. This is all done using .Net 2.0 Compact framework with C Sharp. This is my current code. Form MediaForm = new frmMediaForm(); MediaForm.Show(); this.Hide(); This what I'm thinking I need to do instead. pnlMediaForm.Show(); pnlCurrentForm.Hide(); Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86401

When i draw the middle image it moves 1 pixel to the right and goes 1 pixel out of the display bounds... i don't know why, here's what i am doing protected override void OnPaint(PaintEventArgs e) { gxBuffer.DrawImage(topBar, 0, 0); gxBuffer.DrawImage(middleArea,new Rectangle(0,this.Location +topBar.Height,this.Width,this.Height),new Rectangle(0,0,this.middleArea.Width,this.middleArea.Height), GraphicsUnit.Pixel); gxBuffer.DrawImage(buttomBar, 0, this.Location.Y - buttomBar.Height); e.Graphics.DrawImage(offScreen, 0, 0); } although when i place the middleArea image in a picturebox and stretch it, it works well.... any pointers would be really apreciated Thanks Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86396

    - Button Backcolor property not working even with SP2 installed Hi, I have been trying to get the backcolor property of the button control to work under the .NET compact framework with a custom Windows CE image, but I am having no luck. The problem only seems to occur when running the application on a customised Windows CE image. If I run the application in the Windows CE 5.0 emulator, in Windows XP or on an ARM based Pocket PC 2003 I can successfully change the background colour of a button. However when I run the application on a customised CE 5 or CE6 operating system on X86 based hardware the button doesnâ??t change colour. I have tested the forecolor property of the button control and I can successfully change this colour. I have also tested the radiobutton, and checkbox controls as they both inherit from the same buttonbase class. I can successfully change the background colour of these controls. I have double checked that I have SP1 of VS2005 and SP2 of the .NET Compact framework 2.0 installed on both the development machine and CE image. The CE image reports .NET version 2.0.7045. I would be very grateful if anyone could point me in the right direction with this problem as I am struggling to understand it.

    - Suspend mode We have been having a few problems with a customer of ours who has several devices running CE.NET 4.2. There are two distinct problems.1) The device is suspended after being left all night, but pressing the power button does not cause it to come back on. A soft reset will get it going, until it goes into suspend mode again. 2) The device is working normally then if he has a problem printing (say), and resets the device (I know he shouldn't!), the device restarts but there is nothing on the screen. If you tap the screen you hear a click, and if you connect is to a PC via ActiveSync you can see the files on the device, but there is nothing on the screen. I have only been able to cure this by a hard reset - a soft reset does not cure it. The device manufacturer says it is my software (and it probably is). What needs to be loaded in CE.NET to ensure the power button responds, and is there any way my software could have removed it? I have done some work in the past using notifications and I think that it must be that it is not responding to the button press. However I cannot see what I can have done that prevents the screen from being displayed even after a reset. The battery is fully charged and it has happened on more than one device. Any suggestions appreciated. Thanks in advance. Andy Baker Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86392

In the past (ASP.NET), I have written many panels or user controls and switched panels on and off when required. This is all in one page. This app, I am doing something very similar. I have made the working area a lot larger so that I can design the panels. I set visible to false, then on certain events, I move the panel position and set visible to true. (I have to move position as I have designed them away from the visible section of the screen).

    - Confusing VM behavior You have heard from me before on our memory utilization saga - I will try to keep this one short and sweet. To make our issue more reproducable, and to just help me see what going on, I put toghether a utility just to eat memory and see if we can cause our issue to be more easily reproducable by creating external pressure. This utility has a List<byte[]>, and every <configurable time period> it does a List.Add(new byte[configurable size]). It catches exceptions, cuts the <configurable size> in half, and keeps going. Each time it adds a byte[] to the list, it also calls GC.GetTotalBytes(true), then pInvokes to GetGlobalMemory status, and logs: CA = total number of bytes in all arrays in the list PM = available physical memory from call to GetGlobalMemoryStatus VM = available VM in the process slot from call to GetGlobalMemoryStatus GC = bytes allocated by GC after collection, from GC.GetTotalBytes I have noticed two interesting behaviors that I am curious if anyone can explain - first, as CA goes up by X, VM goes down by 2X. Does every managed byte really cost you two bytes of VM? Second - as I said, when the allocation fails, it cuts the allocation size in half, and keeps going. I see VM hit 0, and allocations keep happening. CA and GC keep climbing, PM keeps dropping, and VM stays 0. I have even caught an OOM and kept going. Eventually the process just exits memory with no exception - not unexpected, just finishing the tale. Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86382

    - Print image to zebra QL320 using CPCL Hi, all I am trying to print .bmp file (1bpp) to the printer. Bitmap file can be printed in ASCII hexadecimal format. I found following info, but application is in .FrameWork not for CF 2.0: http://msmvps.com/blogs/luisabreu/archive/2007/02/13/printing-for-the-tlp2844-zebra.aspx I am having problem with last param in LockBits - _bmp.PixelFormat BitmapData bits = _bmp.LockBits(new Rectangle(0, 0, _bmp.Width, _bmp.Height), ImageLockMode.ReadOnly, _bmp.PixelFormat); Please, advice I found another example to print photo to the zebra printer: all credits to Richard Jones - see on http://www.binaryrefinery.com/main/default,month,2007-06.aspx I tried, but it didn't work for me... I am using CPCL language to print. public void LoadImage(Bitmap _bmp, int x, int y) { buffer.Append("EG "); buffer.Append("4 "); **** it should be _bmp.Weidth ? or i am missing something buffer.Append(_bmp.Height + " "); buffer.Append(x + " "); buffer.Append(y + " "); for (int xcount = 0; xcount < _bmp.Width; xcount++) { for (int ycount = 0; ycount < _bmp.Height; ycount++) { int gotcol= _bmp.GetPixel(xcount, ycount).ToArgb(); if (gotcol == -1) buffer.Append("F"); else buffer.Append("0"); } } buffer.Append(eol); } Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86376

    - Mobile Json Serializer/Deserializer I've recently begun using Json to transmit data in my projects instead of XML. I've been using the Newtonsoft.Json implementation and have been very happy with the performance and ease of use. I've run into a snag now, because I'm using CE5.0 based devices to contact our services. Unfortunately, I haven't been able to locate good implementation of a Json serializer/deserializer that will work on mobile platforms. I've googled, but only have been able to find non-mobile based implementations, and I don't really want to spend the time to write my own implementation if one already exists. Does anyone know of and can recommend a Json implementation that will work on mobile devices? thanks, John Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86358

    - Help - Referencing/Deploying SQLCE3.1 with VS2008 I recently raised an issue here about how to upgrade my project to VS2008 and retain SQL CE 3.1 rather than upgrade to 3.5. After following what I believe are the correct steps it didn't work as expected. I'll apologise for the length of the posting, but I wanted to provide any information that may be relavant It was suggested that I should upgrade the project and then simply change the reference to the system.data.sqlserverce dll, all made sense. So, I followed these steps : . I installed the 'MS SQL Server 2005 Compact Edition Developer SDK' for version 3.1 . Changed the reference in the project to point to 'C:\Program Files \Microsoft SQL Server Compact Edition\v3.1\SDK\bin \wce500\System.Data.SqlServerCe.dll' that had just been installed. Here is where I noticed something odd, VS displays a version number of 3.0.3600.0 against this reference, but file explorer displays it as 3.0.5300.0 . Rebuilt the project and it's deployment project. The deployment project excludes the sqlce dll's as expected . Taking the SQLCE cabs from the folder 'C:\Program Files\Microsoft SQL Server Compact Edition\v3.1\SDK\bin\wce500\armv4i' that had just been installed, I installed the following ones onto the device, a Symbol MC35 running Windows Mobile 5... sqlce30.dev.ENU.ppc.wce5.armv4i.CAB sqlce30.ppc.wce5.armv4i.CAB sqlce30.repl.ppc.wce5.armv41.CAB . I also installed our application from the cab file that had been created by the deployment project as well as .NET2 that is not installed by default. On starting the application, it takes several minutes before displaying an error screen with the following message... 'File or assembly name 'System.Data.SqlServerCE, Version=3.0.3600.0, Culture=neutral, PublicKeyToken=3BE235DF1C8D2AD3', or one of it's dependencies, was not found.' I've googled this PKT reference and there is quite a bit about it mainly suggesting the the desktop dll has been used by mistake, this didn't really help me. I looked at the filesystem on the device and could not find a copy of the system.data.sqlserverce.dll in either the application folder or the windows folder The only files that appeared relevant to me were in the windows folder... sqlceca30.dll sqlcecompact30.dll sqceer30EN.dll sqlceoledb30.dll sqlceqp30.dll sqlcese30.dll I had expected to find a copy of system.data.sqlserverce.dll somewhere but couldn't. So, taking the copy of this dll file from the folder 'C: \Program Files\Microsoft SQL Server Compact Edition\v3.1\SDK\bin \wce500' I copied it into the application folder and re-ran the application. This time it got a bit further, but I got a 'TypeLoadException' followed by an error message 'Can't find PInvoke DLL 'sqlceme30.dll'. So, back to the sdk files and I found and copied on the missing dll, re-ran the application and voila it works!!! OK, so I got it to work, but why did I have to copy on these two dll's manually, have I missed something somewhere else? If you got this far, thanks for your patience any resonse would be greatly appreciated. Chris Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86348

    - Button onPaint event doesn't fire?!?! Hi all, I am writing a class that inherets from the Button control to draw a custom image on it. I override the OnPaint event but it never gets called and the button draws the default shape n color... any ideas why it might be doing that? Thank here's the code: public partial class OSImageButton : Button { Bitmap _Image = null; Bitmap offScreen; Graphics gxBuffer; public OSImageButton() { InitializeComponent(); offScreen = new Bitmap(this.Width, this.Height); gxBuffer = Graphics.FromImage(offScreen); } public OSImageButton(IContainer container) { container.Add(this); InitializeComponent(); offScreen = new Bitmap(this.Width, this.Height); gxBuffer = Graphics.FromImage(offScreen); } public Bitmap Image { get { return _Image; } set { _Image = value; } } protected override void OnPaint(PaintEventArgs e) { if (_Image != null) { gxBuffer.DrawImage(_Image, 0, 0); e.Graphics.DrawImage(offScreen, 0, 0); } else { base.OnPaint(e); } } } Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86333

    - Problem waking up device... I think I've tried everything... Hi all, I have been for almost 2 days trying everything. I need to wake up the device once the PDA is in idle mode (the user pressed the power button) I tried with SetSystemPowerState,RunAppAtTime and they don't work. The only one that works is using the attached code. The problem is once the device is waken up it will show a Notification dialog. If I change the NotificationAction to something different (the available options are Led,Private,Repeat,sound,Vibrate) it just doesn't wake up. I thought that maybe the device was really awake but the screen was off, but it doesn't, because I did some testing with a timer and writing some text to the screen and it doesn't write any text until I press the Power button again. Here is the one that works but it shows that damn dialog: OpenNETCF.WindowsCE.Notification.UserNotificationTrigger trigger = new OpenNETCF.WindowsCE.Notification.UserNotificationTrigger(); trigger.Application = GetAppPath() + "\\Power.exe"; trigger.Type = OpenNETCF.WindowsCE.Notification.NotificationType.Time; trigger.StartTime = DateTime.Now.AddSeconds(20); OpenNETCF.WindowsCE.Notification.UserNotification n = new OpenNETCF.WindowsCE.Notification.UserNotification(); n.Action = OpenNETCF.WindowsCE.Notification.NotificationAction.Dialog; n.Title = "Reminder"; n.Text = "test"; OpenNETCF.WindowsCE.Notification.Notify.SetUserNotification(trigger, n); Any help would be appreciated.

    - Installer Project - No device-compatible programs available I have written an app for WM6. When I debug it using the any of the Windows Mobile 6 Emulators it runs fine. Same if I debug to a real device. I need to package the app for deployment. I've been through all the various walkthroughs including Christopher Tacke's Deploying .NET Compact Framework 2 Applications with .cab and .msi Files. The .cab and the .msi files build OK but when I try to install to any of the Mobile 6 Emulators I get "There are no device-compatible programs available". If I copy the cab to the device and install it via File Explorer the installation seems to proceed OK but then no program appears on the device. I'm using VS2008 but built the same stuff with VS2005 Sp1 and same happens. Any hints please? -- Bob Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86325

    - Options for communication with the device Hi, I am looking at commincation options. Here are my thoughts so far, your comments would be appreciated. What I need to do is to be able to export from a desktop app and also allow the desktop app to drag (import) from the pocket device. What I would also like to do from the pocket device is to 'push' the data to the desktop app. (I could also have the pocket device pull the data) The data is typically XML files. 1. wifi: I would assume that I would need to have a server of some sort on the pocket device. The desktop app would probably need to poll the network for pocket devices in order to hook up. 2. Bluetooth: I have no ideas as to how I would implement this. Any pointers? 3. USB: (not activesynch). Any ideas? 4. Activesynch: How would I hook into activesynch to synchronise my device? Any other methods? The way I am currently doing it is to explore the device from the desktop and drag/drop the required XML file. This is a poor method of doing it. I want to be able to have buttons on the device/desktop application that will do all of the handling. Any sample code / webpages with any of the above options would be very much appreciated. -- Best regards, Dave Colliver. http://www.AshfieldFOCUS.com ~~ http://www.FOCUSPortals.com - Local franchises available Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86324

    - Cannot deploy or debug with VS2005 or VS2005 This is one bizarre problem. Last week I was working on this project with no problems today I tried to deploy and it said deployed successfully but it was to fast, I checked device and no it did not deploy. After trying to get it going for many hours summary is this. In VS2005 and VS2008 it cannot deploy or debug to any emulator or device (I have few pocket PC available) To make thing more confusing after first try menu Deploy in VS is gone, to get it back you need to close solution ad open it again. Deploy does not return any error it always comes back immediately saying success. Trying to run (F5) will come up with error Unable to start program 'CSIDL_PROGRAM_FILES%\SmartDeviceProject1. Manually copying all files to device and then try to debug does work I tried creating new project same story. Everything works perfect in VS2003, this is just confirmation that nothing is wrong with ActiveSync or device Help Tag: System.Drawing.Bitmap.save fails on win CE 5.0 Pro Tag: 86320

    - Out of Memory Error w/Image from HBitmap I have a subroutine (posted here) that takes a image from a file and resizes it and loads it onto a PictureBox. There is a timer elsewhere that sends the routine a new filename to use. The routine works fine until the 77th file or so. (The file names are randomly assigned so they vary each time, but the number of succesful loops is around 77 before the error is thrown.) The error is: Process Image ErrorOutOfMemoryExceptionat Microsoft.AGL.Common.MISC.HandleAr() at System.Drawing.Image.FromHbitmap() at ShowSlide.Form1.ProcessImage() at ShowSlide.Form1.Timer1_Tick() at System.Windows.Forms.Timer._WnProc() at System.Windows.Forms.ApplicationThreadContext._InternalContextMessages() at Microsoft.AGL.Forms.EVL.EnterMainLoop() at System.Windows.Forms.Application.Run() at ShowSlide.Form1.Main() The error continues to happen each time after that.
