    - Long WeakReferences do not seem to work on the CompactFramework. Bug? Hi all, the following C# line throws a System.ArgumentException if I run it on the PocketPC 2002 Emulator or on my iPAQ: new WeakReference("Boom", true ); I am using MSDE 2003 Version 7.1.3088 and .NET Framework 1.1 Version 1.1.4322 Is this a known issue? While I am at asking questions: Where do I send bug reports as a (very new) member of MSDN? Thanks!

According to articles I've found such as this one - http://msdn.microsoft.com/vbasic/using/building/windows/customcontrols/default.aspx?pull=/library/en-us/dnnetcomp/html/customctrlscompactfx.asp - you simply need to add a bitmap to your solution with the same name as the class for your control...

    - Frame Rates in Games I am in the midst of porting my Personal Java game to C# and the Compact Framework. I'm just starting to get it working, but it's running very slow so far. I'm guessing it's running about 6 frames per second on the Compact Framework whereas I'm getting a good 16-18 frames per second using the Jeode Java runtime on the same device. I'm not very experienced with C#, but I'm using the same drawing concepts that I used in the Java version (double buffering with background thread). Perhaps I need to use a different approach with the Compact Framework? What kind of frame rates have other people achieved? I'm using an iPAQ 3835 @ 200 Mhz.

    - COM port access error using CreateFile() Hi, I'm using a Symbol PDT8037 device with a GPRS modem and am trying to access the modem (which is on COM9) so that I can query/change the band information if it is incorrect. With the GPRS band set correctly (to 1900 MHz), I am able to open up the COM9 port to talk to the SIM chip in my device. However, if I change the band to 900/1800 MHz through GSMDemo (a program provided by Symbol that lets you change GPRS parameters), then after exiting GSMDemo I can no longer open the COM9 port using my code (included below - the GetDevice method is being passed "COM9:" as a parameter). GetLastError() returns error code 55 (ERROR_DEV_NOT_EXIST). Even if I soft reset the device, I am unable to open the COM port again till I go back into GSMDemo and change the band information back to 1900 MHz. With the band set back to 1900 MHz, the code below works just fine. Any suggestions on what might be causing this problem? private static uint GENERIC_READ = 0x80000000; private static uint GENERIC_WRITE = 0x40000000; private static int OPEN_EXISTING = 3; private static int m_ihandle = -1; [DllImport("coredll.dll", SetLastError=true)] private static extern int CreateFile( string lpFileName, uint dwDesiredAccess, int dwShareMode, int lpSecurityAttributes, int dwCreationDisposition, int dwFlagsAndAttributes, int hTemplateFlag); [DllImport("coredll.dll", SetLastError=true)] private static extern int GetLastError(); private static bool GetDevice(string Port) { // open the existing port... m_ihandle = CreateFile(Port, GENERIC_WRITE | GENERIC_READ, 0, // comm devices must be opened w/exclusive-access 0, // no security attributes OPEN_EXISTING, // comm devices must use OPEN_EXISTING 0, 0); // hTemplate must be NULL for comm devices //if the handle value is -1, that means you got an error.... if(m_ihandle == -1) { int errCode = GetLastError(); MessageBox.Show("Failed to get COM port - error " + errCode); return false; } else return true; } Thanks, Amol Tag: ANN: eVBtoDotNetForms Ehnanced - Convert eVB forms to VB.Net or C# Tag: 4451

    - Rotating Images I am working on an image viewer application as a learning exercise. Obviously I am making heavy use of the Bitmap and Image classes. In the full framework, there is a method called Image.RotateFlip() that would allow some trivial image manipulation. This method doesn't exist in the Compact Framework. Unfortunately, they also removed the LockBits method that would allow programmers to party on the image bits themselves. The only way I have found in the Compact Framework to rotate an image is by creating a second image of the correct dimensions and then walking over the first image calling GetPixel and then calling SetPixel on the new image. This is just about the most inefficient method of doing anything I have ever witnessed. To rotate a simple 74x124 pixel image on a 400MHz XScale, it takes approx. 1:30 minutes. The time to rotate an image 90 degrees appears to increase exponentially as the image gets larger. Does anybody have a better method of rotating an image with the Compact Framework? If not, then I fear it will be a big flop for the majority of applications, since trivial image manipulation is a fairly common thing. Especially with games!

    - Campaign for KeyDown I'm trying to intercept the arrow and return keystrokes with the KeyDown event. Yes, I've tried the McSoft package and it won't work for me. I believe a TextBox and only one or two other controls make the KeyDown event available. For my testing, added a handler to a textbox's KeyDown event. Upon each event, I added the KeyCode to a combo box. I found some interesting results which I am happy to share here. In all tests, I set the focus to the textbox and pressed the Up, Down, Left, Right and Return keys in order. The test results show the KeyCode.ToString results generated from each physical key pressed. Note that in some cases, one human action produced two events (i.e. two keypresses were generated). Test 1: Emulator; clicking the star pad with the mouse Up, F21 Down, F21 Left, F21 Right, F21 Return Test 2: Emulator, clicking the arrow keys on the SIP Up Down Left Right Return Test 3: Emulator, pressing keys on the host computer Up, F20 Down, F20 Left, F20 Right, F20 Return Test 4: Compaq iPaq, tapping keys on the SIP Up Down Left Right Return and a beep Test 5: Compaq iPaq, pressing the star pad Up, F21 Down, F21 Left, F21 Right, F21 F23, Return and a beep And that leads to a few questions: 1) What's with the the F20, F21 and F23 keycodes? What do they signify? It would make some sense if the F## keystroke always preceded the usual keycode (so the software could perhaps handle the star pad differently from the SIP), but it's a real kludge if the F## keystroke follows the usual keycode. 2) Can I get rid of the beep? I tried setting AcceptsReturn both ways on the textbox and that didn't seem to affect the beep. 3) What other controls support KeyDown detection? 4) Design question: I've got a tab control with 4 tab pages. The tab page of interest to me has a bunch of buttons, combo boxes, trackbars, etc. There's also a bunch of combo boxes and list views that are outside the entire tab control. I don't need the SIP for any of these controls. I'd like to use the Up/Down/Return keys from the star pad. What do you think about this approach: * deriving a class ("MyGizmo") from one of the controls that supports KeyDown (probably not the TextBox since it beeps for Return) * instantiating Gizmo on the tab page of interest * setting the Gizmo invisible (or, if it must be visible in order to get focus, then creating a 1-pixel screen representation) * adding a handler to all the other screen controls' GotFocus event to send the focus over to the Gizmo control * adding a handler to the Gizmo KeyDown event; if the tab control's selected tab page is the one I'm interested in, and the keycode is one of my special keycodes, then do whatever needs to be done and mark the keycode as handled Boy, I sure wish I had a form-level KeyPreview....

    - SDE and network server apps. An issue for the gurus: - How can I debug and test an application (using PocketPC 2003) which exposes a network service on the emulator? For example a simple app using a TCPListener, accepts a connection and dumps data to a listbox. The code was quite easy to write, however... The big problem I have found is getting a device or emulator to be debugged and accessible from my LAN. I imagine I could solve this simply by using my iPaq with a network adapter (say ethernet CF card, wlan) and then use activesync to debug along with having a LAN based IP address on the network to serve to my tcplistener. As a sort of challenge, at the moment my only 2 options are an ipaq 3970 with bluetooth and the PPC2003 emulator. I don't think you can do this at all with the 2002 emulator. Bluetooth is a complete ass (Ipaq 3970 with PPC2003), if I connect to my PC's PAN service and then connect via activesync (either via the cradle or using bluetooth activesync) the PAN connection dies or becomes mute. I did some testing by enumerating the current hostname ip addresses using the Dns class, it seems activesync overrides the PAN IP address with it's own internal IP address or flat out drops the connection. Now I can't claim to be an expert here but I gave up citing bluetooth/pocketpc 2003 connection issues, most likely related to the activesync pass through function (WHICH CAN'T BE DISABLED BTW). Isn't the passthrough is great for outgoing connections but useless for incoming (to device)? Next in line, the emulator in SDE really has me confused, it installs PocketPC2003 targets in VS.NET2003 which almost work fine... Unfortunately, I am fairly sure VS.NET2003/SDE is currently using the 4.1 Emulator.exe to run the CE.NET 4.2 pocketpc 2003 image (why!). This means that the new (4.2) virtualswitch option is not available. The virtualswitch network option allows the emulator to be accessible on my LAN by giving it a LAN accessible IP address, the default alternative is a NAT style adapter (only useful for outgoing originated connections like PIE, and similar to activesync passthrough) subsequently totally useless for my TCPListener service. Anyhow, the virtualswitch function also uses a network plug-in which seems ONLY evc4.0 SP1/SP2 (possibly SDE too) installs into the PC's primary network interface "Virtual PC Emulated Ethernet Switch". I wonder why they didn't use a virtual adapter like widcomm have done in their bluetooth drivers? That would be neat... you could bridge or use ICS or whatever. The PPC2003 emulator from my current EVC4.0 install, doesn't seem to work at the moment although I imagine I just need to remove everything and reinstall. However it does gives me the option for virtualswitch which causes the emulator to have its own LAN accessible IP address. Great in principle and the main thing is I have managed to get it working manually by invoking the emulator myself from the command line. Although I can't seem to get SDE to debug to the manually executed emulator, obviously it needs activesync. I have seen an article which mentions using the emuAScfg.exe but I could not get this to work at all (Any info would be greatly appreciated). I suppose I could setup the partnership with a serial cable... I combed the newsgroups and found other people with similar problems although more complex I guess (some using UDP). However nothing suggests a working solution to this problem, is it just that this sort of thing is "?uncommon?" so far with the compact framework? Conclusively the only options I can think of are: - 1. Give in and use a physical device and a network adapter and activesync over the network. 2. Get the command line invoked emulator to activesync so I can debug (serial or emuascfg.exe). 3. Complain a little that Microsoft needs to fix the SDE integration in VS.NET2003 particularly in regards to the emulator integration for PPC2003. I had a look at the assemblies in the CF folder like ConMan.dll,ConManDataStore.dll... man that is a highly detailed integration! I hope this generates some discussion for people who maybe have run into similar problems. I am still new to the .NET framework and SDE in particular. I just wish this was a little more easy in cases like this. Any corrections/further info would be greatly appreciated. Regards, David.

    - Best practices Greetings, I have a custom control which I am adding to a form. It processes Key events, but if the event is not handled at this control's level, then it needs to pass the event up to the containing form. Currently I am making a call similar to: ((MyForm)((Control)sender).TopLevelControl).MyForm_KeyUp (sender, e); I find this a rather nasty way to approach this as it ruins encapsulation for my control since it needs explicit knowledge of the form that it will be contained in. Is there is a better way to throw this event to the parent form? Cheers, Ian Williamson Tag: ANN: eVBtoDotNetForms Ehnanced - Convert eVB forms to VB.Net or C# Tag: 4321

I'd like to be able to capture keyboard messages at the application level (tab key messages specifically, so I can implement tab navigation). I've done some research, and I've made some progress, but I'm still having problems. First, I'd like to summarize my findings for those trying to solve a similar problem, then I'd like to present problems I'm still having for those of you who might be able to help. Lastly, I'll insert my unmanaged DLL code for your use/inspection. 1. Findings: a. First, I looked for a way to accomplish my goal using only managed code. Then, I looked for a way to do it using the WinAPI from managed code. Ultimately, I settled on what seems to be the most discussed, if not only, approach. I inherited the MessageWindow class in managed code, overrode its WinProc method (see http://msdn.microsoft.com/library/en-us/dnnetcomp/html/messagewindow.asp?fra me=true), created an instance of my new MessageWindow class, and passed the value of the instance's Hwnd property to an unmanaged DLL written using eMbedded Visual C++ that handles hooking low level keyboard events and sending appropriate message back to my MessageWindow class instance (see unmanaged DLL code below). b. Though hooking in general, and SetWindowsHookExW specifically are not documented functionality of the Windows CE API, they do work in a limited fashion (see item 10.9 "SetWindowsHookEx really does work, sort of." at http://www.cegadgets.com/wincedevfaq.htm). c. Note that with respect to keyboard hooks, only low level keyboard hooks are accepted. d. Note that WH_KEYBOARD_LL is defined with a value of 20, not 13 as defined in the WinUser.h file of the Windows platform SDK. e. I first tried to download and use eMbedded Visual C++ 4.0 to no avail. I later found an article (paragraph 6, http://msdn.microsoft.com/vstudio/device/embedded/evcandcenet.aspx) which suggested I needed eMbedded Visual Tools 3.0 (http://www.microsoft.com/downloads/details.aspx?familyid=f663bf48-31ee-4cbe -aac5-0affd5fb27dd&languageid=f49e8428-7071-4979-8a67-3cffcb0c2524&displayla ng=en) instead. 2. Problems: a. Using my ultimate approach as detailed in 1.a above, and the unmanaged DLL code attached in item 3 below, I've been able to successfully capture low level keyboard messages in the emulator. However, I haven't been able to capture tab key messages in the emulator. I've seen one person recommend the age old, ALT approach to indicating special characters (e.g. if in MS Word you press and hold the ALT key, then type 090, the result is Z). In other words, if the emulator window has focus and you type ALT+009, the emulator should simulate pressing the tab key. However, this doesn't work for me. Does anybody else have some suggestions? b. While my approach mostly works in the emulator, it hardly works with my actual Pocket PC and keyboard (I have a Dell Axim with the Dell foldable keyboard). The only key down messages my DLL sees when running on my Dell with a real keyboard are some of the non-standard keys like Caps Lock, Shift, etc. Does anyone have any ideas why this is? Are keyboard hooks tightly tied to specific makes and models of Pocket PC's and attachable keyboards? c. While I've seen some good technical articles about marshaling between managed and unmanaged code, either they did not explain or I overlooked how to dereference a pointer to a struct passed by unmanaged code to managed code (most of the discussion seemed to center around passing structs from managed code to unmanaged code). Specifically, I'd like to know how to get at the KBDLLHOOKSTRUCT struct behind the LowLevelKeyboardProc's lParam pointer that I pass on to the managed MessageWindow class from managed code using C#. 3. Unmanaged DLL code: // ******************* Header ******************* #ifdef TESTLIBRARY_EXPORTS #define TESTLIBRARY_API __declspec(dllexport) WINAPI #else #define TESTLIBRARY_API __declspec(dllimport) WINAPI #endif #ifdef __cplusplus extern "C" { #endif typedef LRESULT (CALLBACK* HOOKPROC)(int code, WPARAM wParam, LPARAM lParam); typedef struct KBDLLHOOKSTRUCT { DWORD vkCode; DWORD scanCode; DWORD flags; DWORD time; ULONG_PTR dwExtraInfo; } KBDLLHOOKSTRUCT, *PKBDLLHOOKSTRUCT; HHOOK SetWindowsHookExW(int code, HOOKPROC, HINSTANCE hInstance, DWORD threadId); int UnhookWindowsHookEx(HHOOK hhook); int CallNextHookEx(HHOOK hhook, int code, WPARAM wParam, LPARAM lParam); int TESTLIBRARY_API SetKeyboardHook(HWND messageWindow); int TESTLIBRARY_API UnhookKeyboardHook(); #ifdef __cplusplus } #endif // ******************* Source ******************* #include "stdafx.h" #include "TestLibrary.h" #define WH_KEYBOARD_LL 20 #define MSG (WM_USER+1) HHOOK mKeyboardHook = NULL; HWND mMessageWindow = NULL; HINSTANCE mThisInstance = NULL; BOOL APIENTRY DllMain(HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved) { switch (ul_reason_for_call) { case DLL_PROCESS_ATTACH: case DLL_THREAD_ATTACH: mThisInstance = (HINSTANCE)hModule; case DLL_THREAD_DETACH: case DLL_PROCESS_DETACH: break; } return TRUE; } LRESULT CALLBACK LowLevelKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam) { if (nCode < 0) return CallNextHookEx(mKeyboardHook, nCode, wParam, lParam); SendMessage(mMessageWindow, MSG, wParam, lParam); return CallNextHookEx(mKeyboardHook, nCode, wParam, lParam); } int TESTLIBRARY_API UnhookKeyboardHook() { if (mKeyboardHook == NULL) { return FALSE; } BOOL status = UnhookWindowsHookEx(mKeyboardHook); mKeyboardHook = NULL; if (status) { return FALSE; } return GetLastError(); } int TESTLIBRARY_API SetKeyboardHook(HWND messageWindow) { UnhookKeyboardHook(); mMessageWindow = messageWindow; mKeyboardHook = SetWindowsHookExW(WH_KEYBOARD_LL, (HOOKPROC)LowLevelKeyboardProc, mThisInstance, 0); if (mKeyboardHook) return FALSE; return GetLastError(); } Thanks, Ben Urbanski Tag: ANN: eVBtoDotNetForms Ehnanced - Convert eVB forms to VB.Net or C# Tag: 4309

    - Getting Line Number of Error I'd like to access the line number of the last executed line of code, so I can have my Catch statement display it. In VB6, I used the Erl() function to do this - is there anything comprable that can be used in .NET CF? I'd even settle for forgoing the Try...Catch and just having the error show the unhandled error message - if only the line number could be displayed here. Is this even possible?

    - accurate timers Hi I'm using a timer that is triggered each second to perform a countdown. Once the countdown hits one, I reduce the timer interval by a safety margin, and the next time the timer callback kicks in, I turn on packet reception in my program. The next timer interval is one second plus the safety margin, and is reset once the first packet containing an indicator of the next data transmission is received. This mechanism works accurately on my client software running on a pc, it is always in synch with the server, even though they run on different machines (the client is even connected through a wlan). However, if I do the same on PocketPC, if I show the counter in the GUI I can already see that it doesn't match the countdown on the client and the server PC, and sure enough, the PDA gets out of synch quite often (it manages to catch up eventually, but the whole point of my data transmission mechanism is that a client listens at the beginning of the data transfer, and shuts down as soon as it has all the data it needs). My first thought was increasing the priority of the underlying thread of my timer (Threading.Timer), but I didn't find a way to expose that thread and as there is no other timer class I'm aware off, I'm a bit stuck here. I know I could increase the leeway period to several seconds and I'd be sure to get all the data I want, but that would effectively equal to doubling the listening time and render my whole transmission scheme 50% less effective (and require twice as much power... wlan uptime is expensive) and that would just about break my neck. Any help in that matter would be very welcome. Regards Stephan Tag: ANN: eVBtoDotNetForms Ehnanced - Convert eVB forms to VB.Net or C# Tag: 4297

    - Reading from COM port (Ipaq + GPS module) Hi, I am trying to access the Haicom HI-303MMF GPS modul using C# (.Net Compact Framework on Pocket PC). The NMEA data that it produces can be read from the (virtual) COM6 port. I try to open a connection with the COM6 port using CreateFile like this: ====== [DllImport("coredll.dll",SetLastError=true)] private static extern unsafe int CreateFile..... ... m_ihandle = CreateFile("COM6",GENERIC_READ, 0, 0, OPEN_EXISTING,0, 0); ... ===== This works when COM6 is replaced by COM1, but COM6 gives me the error (obtained by the GetLastError function): "2: The System Cannot find the file specified." I also tried using "COM6:", "//./COM6", "//./COM6:" and "\\\\.\\COM6" as identifier, but they also fail. Is there something I should take into account because of the high number of the COM port?

    - Is TabIndex not supported? I was trying to compile some code in the dos prompt for the PPC. It keeps telling me, however, that TabIndex is not supported. I get: Dice.cs(90,4): error CS0117: 'Dice.WinForm' does not contain a definition for 'SuspendLayout' and Dice.cs(108,4): error CS0117: 'System.Windows.Forms.Button' does not contain a definition for 'Name' and Dice.cs(120,4): error CS0117: 'System.Windows.Forms.Button' does not contain a definition for 'TabIndex' I am very confused? I thought C# was the same everywhere? How do I know what is supported or not? Tag: ANN: eVBtoDotNetForms Ehnanced - Convert eVB forms to VB.Net or C# Tag: 4280

    - CF SP1 QFE for CE.NET 4.1 ? Can anyone please tell me when MS will produce the QFE for CF SP1 for Windows CE.NET 4.1 ? The 4.2 QFE appears to be available, although the QFE description is a bit cryptic (is it or isn't it the CF SP1). Surely such as QFE should appear on the main QFE download page.

    - OpenNetCF (Desktop Communications.RAPI) question First off, you guys absolutely RULE for creating this set of libraries for the rest of us to use! My question is in regards to CopyFileFromDevice() I'm basically copying the log.xml file from the device over to my desktop. i.CopyFileFromDevice("\program files\sd_dispatch\Log.xml", "C:\log.xml", True) All I ever get is "Cannot Access Remote File" The log file exists on the device, but it never gets moved over. I tried creating an empty file there, but same error when it gets to CopyFileFromDevice(). dim strFile as string = "C:\log.xml" Dim f As System.IO.File If f.Exists(strFile) = True Then f.Delete(strFile) Dim sr As System.IO.StreamWriter = f.CreateText(strFile) sr.Close() f = Nothing sr = Nothing I do have another question as well, how would I tell if a file exists on the device? Can I just use system.io.file to hit the device? I want to make sure I handle any errors relating to the missing files on the device correctly. This log file is one of 3 files that need to get transferred via RAPI. Thanks!!! // Dave (I didn't mean to make it a response to that Sai's post, but it's showing up that way for me!

    - Forms Designer quits working The Forms icon suddenly stopped coming up in the Solution Viewer on 2 of 3 forms. Right-click "open with" on a Forms source file did NOT offer the designer as an option. After comparing vbproj and vbproj.user files between the problem solution and a "Hello World" project, noticed a complicated "Reference Path" in the vbproj.user file. Eliminated the ref path and got the designer back. I don't explain, I just report. From working vbproj.user file: <VisualStudioProject> <EVisualBasic> <Build> <Settings DeploymentDevice = "Windows CE Emulator" ReferencePath = "" > Guess I need to SourceSafe more often.

Hi,

eVBtoDotNetForms has been enhanced to convert eVB forms to VB.Net or C#. We
do NOT translate the code, but do
reproduce your eVB forms in your chosen .Net language. This can save hours
of work when migrating your project.

In addition, we also support the excellent GroupBox from www.opennetcf.org,
which is far more like the
eVB frame than the panel control.

Demo versions are available from
www.gui-innovations.com/html/evb_to_dotnet_forms.html and the software is
$29.99 to buy.
Demo version will convert your code, but will not allow you to save it
