    - C++ and C# calling each other i've been mulling over this for. from what i gather, a more realistic solution to a PPC app in .netcf2 is to have a combination of C# (usually for UI - a lot less coding is involved) and C++ (usually in a DLL of some sort to do the low level stuff). so i've figured out how you can call a C++ dll from C# via P/Invoke. neat! my question is, is there a similar mechanism for a C++ dll to call some C# code? i'm thinking there might be situations where my C++ DLL may do work that is asynchronous and will later post the result back to the C# code. perhaps a window message is a better way to communicate? how do people do this? or is it rare and almost unnecessary for C++ to call C# in practice? i don't want to go down a path of endless nightmares and back-to-the-drawing-board scenarios.

    - VS2005 Perf issues with SmartDevice projects Well after experimenting for a few more days I have narrowed this problem down to it only occuring with SmartDevice projects. It appears to occur as soon as I end a VPN session. I start VS2005 do some development then log into our coorp network with VPN and log out. Immediately after all any SmartDevice project will show these symptoms. I can exit and restart VS2005 but problem remains until I reboot. Help!!! I just installed VS2005 and have noticed that during builds for CompactFramework devices the env. is extremely slow around the PostBuild phase. It sometimes takes 1-2min to build a project. This problem did not exist in the Beta2 release with the same projects and solutions. I have not been able to figure this out. I may need to uninstall R1 and rinstall Beta2 because this performance is really bad. >> >> Any tips. >> >> Thanks Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61588

    - 32Mb is not enough memory for App Hi all, From what I've read each CE app can only use 32Mb of memory, is there anyway to expand this? Our App is rather large and demanding, and sometimes the app runs out of memory, usually while doing Sql-stuff. I've looked into VirtualAlloc, but firstly I don't /really/ understand it, and secondly, it seems to makes no difference in our App. Below is an app I whipped up to test memory usage. On my device it runs 39 times, then throws an out of memory exception both with, and without the VirtualAlloc code commented-out. [VB.NET] Public Class Form1 Inherits System.Windows.Forms.Form Public Shared Sub Main() Application.Run(New Form1) End Sub <System.Runtime.InteropServices.DllImport("coredll")> _ Private Function VirtualAlloc(ByVal lpStartAddr As IntPtr, ByVal size As Integer, ByVal flAllocationType As Integer, ByVal flProtect As Integer) As IntPtr End Function <System.Runtime.InteropServices.DllImport("coredll")> _ Private Function GetLastError() As Integer End Function Private MEM_RESERVE As Integer = &H2000 Private MEM_COMMIT As Integer = &H1000 Private PAGE_READWRITE As Integer = &H4 Private PAGE_NOACCESS As Integer = &H1 Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Visible = True Application.DoEvents() Dim offset As Integer = 1 'Dim x As IntPtr = Me.VirtualAlloc(Nothing, 2 * 1024 * 1024, MEM_COMMIT Or MEM_RESERVE, PAGE_READWRITE) 'If x.ToString() = "0" Then ' MessageBox.Show(Me.GetLastError().ToString()) 'End If Try While True Dim p As New PictureBox p.Bounds = New Rectangle(offset * 8, offset * 8, 25, 25) p.Image = New Bitmap(500, 700) Me.Text = offset offset += 1 Application.DoEvents() End While Catch ex As Exception MessageBox.Show(ex.ToString()) End Try End Sub End Class [/VB.NET] Thanks for reading, and I hope someone is able to help/advise me Tag: Advanced Newbie: is MsgBox eating my TextBox?

    - Help with deceiding on best solution Hello all, I am about to embark on a reasonably large project - I operate an energy management business and need to install remote controls at a large number of my clients sites. My plan is to utilise windows CE devices at the clients sites - they should be low in cost, reliable (as they have no moving parts) and the development process should be relatively straight forward - it should also make the communications to the devices simpler and allow me to extend the functionality well into the future. The devices will have a number of communication options - these include GPRS modem, clients internet connection via wireless of RJ45 - or GPS modem. The area that I still need to finalise is the method of communication and the technology to use. The following will be true 1. Communications will need to be over the internet 2. The internet connection will often use a clients internet connection therefore there will be no ability to have a fixed IP address on the devices 3. It must efficient - if the communication is over GPRS the costs of transmitting data will be high 3. There will be a large number of devices - the system needs to be scalable to 100,000's of devices 4. The remote devices will need to send information to our office 5. We will need to be able to send info to the devices with a very small delay 6. Communications must secure - it will be critical that no one can hi-jack and control the devices I have investigated the new WSE 3 and this sounds like a good option for communication?? It appears to have the security requirements and easily scalable to manage the communications for this many devices - can windows CE take advantage of the security features of WSE 3. Any help from those that may have some experience in these matters would be very appreciated. -- matthew Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61542

    - Setup moans because of newer version I'm writing software for the QTek 2020 at the moment which is running Pocket PC Version 4.20.0. However we're just starting to rollout the same software on the XDA II running Windows Mobile 2003 Second Edition version 4.21.1088. The software actually works OK however when it tries to install SQLCE and SP3 for the .NET Framework it's coming up saying "this software was written for a previous version of software, and may not work, do you want to continue with the install" Is there anyway to get around this?

    - WM_SIZE and WM_SETTINGCHANGE not fired in WinCE.NET Hi to all NG. I'm unable tu understand why in WinCE 4.2 while rotating the screen, the WM_SIZE and/or WM_SETTINGCHANGE messages are not fired from the system (so I can't get the Resize event). In this way I can't understand when redim my form to the new screen size. I've seen that neither Word or Explorer redim theyself (and they are _original_ Microsoft products, so I can think that they are well made). Can be that WinCE isn't designed for real-time screen rotating (but only during CE startup -> once a boot) while Windows Mobile yes? Is this the reason? I can rotate the screen directly from my application, calling the ChangeDisplaySettingsEx. In the MSDN http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrfChangeDisplaySettingsEx.asp you can see that calling that API a WM_SETTINGCHANGE must be fired, but I can't get that message neither in my C# app (using Microsoft.WindowsCE.Forms) neither in a simple C++ application. Any suggest? Thanks Massimo Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61530

    - Consider app.config remapping of assembly Folks, I have a Smartphone Solution with two Projects: 1) Common References, among others System and System.Windows.Forms 2) Foobar References, among others: Common, System, and System.Windows.Forms The Common Project compiles with no warnings. Foobar, on the other hand, compiles with the following warnings: Consider app.config remapping of assembly "System.Windows.Forms, Culture=neutral, PublicKeyToken=969db8053d3322ac, Retargetable=Yes" from Version "1.0.5000.0" [] to Version "2.0.0.0" [C:\Program Files\Microsoft Visual Studio 8\SmartDevices\SDK\CompactFramework\2.0\v2.0\WindowsCE\System.Windows.Forms.dll] to solve conflict and get rid of warning. Consider app.config remapping of assembly "System, Culture=neutral, PublicKeyToken=969db8053d3322ac, Retargetable=Yes" from Version "1.0.5000.0" [] to Version "2.0.0.0" [C:\Program Files\Microsoft Visual Studio 8\SmartDevices\SDK\CompactFramework\2.0\v2.0\WindowsCE\System.dll] to solve conflict and get rid of warning. Each Project is referencing EXACTLY THE SAME DLL (V2.0.0.0). Nothing is referencing V1.0.5000.0 DLLS. In an attempt to fix this, I created new Projects, added the items from the original Projects, re-added the References, and then removed the original Projects from the Solution. The first time I built the Solution there were no problems. Subsequent builds throw the error message. In another attempt to fix this, I created a foobar.exe.config and added this: <assemblyBinding> <dependentAssembly> <assemblyIdentity name="System.Windows.Forms" Culture="neutral" PublicKeyToken="969db8053d3322ac" Retargetable="Yes" /> <bindingRedirect oldVersion="1.0.5000.0" newVersion="2.0.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System" Culture="neutral" PublicKeyToken="969db8053d3322ac" Retargetable="Yes" /> <bindingRedirect oldVersion="1.0.5000.0" newVersion="2.0.0.0" /> </dependentAssembly> </assemblyBinding> This has no affect on the build; the error messages remain. I am at a total loss. Any suggestions are gratefully appreciated. Thanks. Joel Finkel finkel@sd-il.com Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61526

    - Smart Device / Web Service development on the road? I am in the process of developing a CF2.0 based app using VS2005. The app is a client for a desktop software package and I am using web services to communicate from the device to the desktop. I spend some amount of time on the road with no network connection to my laptop, but I would like to be able work on this application. This would require setting up the emulator or a synced device with a network connection. I am wondering how to set up this networking scenario because with no wireless or wired network connection I have no ability to assign an IP. Am I missing something simple? Is there a way to set this up? Thanks! Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61525

    - Rs232 access under Netcf I am migrating a set of Apps from the desktop to Netcf. One uses Rs232 access. It uses the techniques outlined in the Msdn article " Use P/Invoke to Develop a .NET Base Class Library for Serial Device Communications" which includes the classes CommBase and CommLine. Unfortunately the CreateFile() does not work. Do you have any idea if the approach specified in the article can be made to work at the Netcf level. If not is there another alternative.

    - WM5 Cab problem I have an application that references Ver 1.2 of OpenNetCF. When I create my cab file and install it to a new device it works fine as long as i already installed OpenNetCF. Or at least it works on WM2003. But today I got an Axim x51 with WM5. Now when I try to install my application from a cab file, it wont even copy the files to the directory. It says that it installed correctly, but it doesnt even create the program directory. Ive slowly been deleting things from the cab file to find out what is hanging it up, and when i delete the reference to OpenNetCF it installs fine. Just wondering if anybody else has had this problem. Ive installed OpennetCF. And if i manually create my program directory and copy the files in by hand, the program runs perfect. Its just the cab file that wont deploy when OpennetCF is included in my references. I would hate to have to strip out my opennetCF code, cause its a great tool.

    - Windows Mobile app communicating with a Service I was wondering if it is possible to create a Windows Service in C# and then have a Window Mobile app send requests / communicate with that service? What I would like to be able to do is send requests from the Mobile app to the service, the Mobile app would go to wait state, the Service would execute a threaded query or non-query against a non-SQL Server database, then the service returns information back to the Mobile app. If I can get this working, there would be possibly 30 - 40 mobile devices running simultaneously requesting from the service. Is this something that is possible? If so, where do I need to start as far as research? Thanks, David Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61481

    - Developing for Windows Mobile 5.0: State of the art Hi! I am starting development for Windows Mobile 5.0. I have received and intalled the "Windows Mobile 5.0 Developer Evaluation Kit" including Visual Studio .NET 2005 Beta 2. I have just received the Windows Mobile 5.0 device and it has not .NET CF 2.0 installed... So I am trying to install the up to date version of .NET CF on my device so that I can start developing. While browsing the web for this up to date version I have been confused by the many versions of the .NET Framework available. I would really appreciate it if someone could clarify the situation for me. I have found that the .NET 2.0 and .NET CF 2.0 final are available. However, as I am using Visual Studio 2005 Beta 2 it seems that I can't use these versions, I have to stick to the .NET 2.0 Beta 2 and .NET CF 2.0 beta 2. Is that correct? Finally, I have seen that Visual Studio 2005 Final has been launced on 11/7. I have been through the license of Visual Studio 2005 Beta 2 a long ago, and as far as I can remember users must sease using it as soon as the final version is out. Therefore can I still use my Beta 2 version today ? or do I have to order now the final version? Thanks a lot, your clarifications will be useful.

What a mess the hellish MSDN Subscription is! I can see Professional Edition 2005 with 10/28/2005 release date and Team System Release Candidate with a newer release date. Which version is the latest stable? That is, MS announced few weeks ago that MSDN Universal Subscribers could download VS.NEt 2005 final version while DVD is shipped to subscribers. I think they talked about Professional edition but..........I would like to hear you, developer's opinion. Thanks. Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61463

    - Digitally signing CABS Hi, How is everyone else working with digital signatures in cabs. My understanding is if I sign it then it will only work on smartphones, or with AS4. If not then it makes the cab useless... Is everyone producing two cabs, or have you come across another solution? Mike Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61462

    - USB event notifications Hello, I'm new to .NET development in general, and I can't seem to find the answers I need anywhere else. Is there a way in the compact framework to detect the insertion/removal of a USB memory stick? I have C# code which needs to inform other modules of these events (specifically flash memory devices; I'm not interested in other USB device insertions). I also need to be able to determine the path to the device (assuming I can still treat it as a regular drive) and perform read/write operations. I've seen this question posted on other groups, but they seem to all have answers based on the use of WMI and the System.Management API of the full .NET framework. Am I right in saying that this doesn't exist for the compact framework? Any answers, links to code samples, other discussions or documentation would be greatly appreciated. Thanks, Ross Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61460

    - Auto reconnect to a WiFi connection I need to make an application (on a Pocket PC 2003) that automaticaly reconnect when a connection is available. The application is connected live to a SQLServer 2000 and when i get a broken connection, It shoud display a message to the user "Network connection lost, Reconnect?" Ok = Try to connect to the network (available configured AccessPoint) an perform operation Cancel = discard operation an wait until user try again (the message will loop until success or cancel) The application is destinated to verry novice user and should be the most transparent as possible... down want them to get to the device settings... I'have tryed many things and nothings seem to work! What i'm doing wrong... is it my device? Is i understand something wrong? The pocket PC is a DELL AXIM 2 Wifi acces point (MYACCESSPOINT no WEP KEY and MYACCESSPOINT2 with WEP KEY) developping in C# using Visual Studio 2003 Compact Framework 1.0 with latest service pack. When i start Internet explorer, it automaticaly connect one of my prefered access point! I also notice that where i am doing test there is a lot of not configured device (and should hide the connect to a new network wizard) == First setup: == I configure both as prefered devices and connect to one acces point - I write a simple apps that open a connection on a SQL server on the network - I goes out of scope the two acces point - I came back near the acces point and wait... (1 minute and more) - Try to re open the connection an get an error like "server does not exists" == Second setup: == I read a bit an try the fallowing (with OpenNETCF), after the error "server does not exists" i call my function TakeConnection() but the code never break... so never get connected.. ;o( private void TakeConnection() { ConnectionManager oCon = new ConnectionManager(); foreach( DestinationInfo d in oInfo ) { bool connected = false; if(d.description == "work") { oCon.Connect(d.guid, true, ConnectionMode.Asynchronous); while(!connected) { if(_oCon.Status != ConnectionStatus.Connected) { System.Threading.Thread.Sleep(1000); continue; } connected = true; } } } } == Third setup: == I keept a member instance of ConnectionManager and call a function like DoConnection at the form initialisation. (same as TakeConnection with the global member) The function also register to events OnConnect, OnDisconnect, OnConnectionFailed, OnConnectionStateChanged... When i start the app, i got the OnConnect, but when connection goes out of my access point, never got disconnected or anythings else... also never get reconnected when the AP becone available. == Fourth setup: == I tryed SetWirelessSettings to force the reconnection to one of my acces point, it work fine except that the way the function seems to be impelemeted (in OpenNETCF 1.4) wipe out all my prefered device and their configuration. When i call the fallowing code, the wep key of *ALL* my prefered access point are gone... (MYACCESSPOINT doesn't get wep key but MYACCESPOINT2 does) OpenNETCF.Net.AdapterCollection oCol = OpenNETCF.Net.Networking.GetAdapters(); foreach(OpenNETCF.Net.Adapter a in oCol) { if(a.IsWireless) { a.SetWirelessSettings("MYACCESSPOINT", true, (byte[])null); a.RebindAdapter(); } } if I could fix theese two issue, this could be a nice solution: - Retreive a way to get the wep key of the AP configured in the deveice (settings) - Find a way to SetWirelessSettings without mixed up all the AP configuration ==Conclusion =========== Thanks a lot for your help, please help me to get samples or full articles helping me to demystify that, my deadlines are really short and have no clue where to look anymore!

    - VS2005 Remote Tools connectivity issues How do I get the Remote Tools that come with VS-2005 to work with my Custom WinCE emulation image. My emulator is not displayed in the "Select a Windows CE Device" dialog when I lauch Remote Registry Editor. The only custom platform I see is the device image I created but not the emulator one. Note: When I launch eVC++ Remote Tools I can connect to my emulator. However, when I do this it launches another emulation env. that does not allow me to connect to the one I am debugging using VS-2005. Thanks Tag: Advanced Newbie: is MsgBox eating my TextBox?

    - best way to trap keyboard input i've done this via a form but what if i want some global keyboard input trapping? e.g. irregardless of which form i am in, i want my app to do something when the user presses on 'A'. what is the best mechanism for doing this? is there a place where i can define a global keyboard handler trap so that i don't have to implement KeyPress event handlers in all my forms?

    - Windows CE 4.2 and .NET Compact Framework 2.0 This may be old news to a lot of you, but it's was very good news to me: http://pluralsight.com/blogs/jimw/archive/2005/11/14/16776.aspx Thore Berntsen Tag: Advanced Newbie: is MsgBox eating my TextBox? Tag: 61447

I defined Tx_upd_memo as TextBox on a form.

Here is my code:

MsgBox(Tx_upd_memo.Text, , "1 memo")
MsgBox(Tx_upd_memo.Text, , "2 memo")

First I see values that I entered on the form. Next I see only values
that were originaly displayed on the form.
Is MsgBox modifying Tx_upd_memo.Text?
