    - DefaultButton Hi. Is there a way to make a certain button on a form (OK Button) the default button as you can do in a regular windows application with .NET? I would like to make Enter click invoke this button by default or do you have to write kode capturing Enter click and fire a buttonClick event on the desired button? //Regards <P> Tag: Big database application + Emulation Tag: 20070

    - MSMQ - WIndows CE We are planning to use MSMQ for store and forward mechanisim on our Pocket PC 2003. We are using the .NET as our development environment. .NET does not allow us to use the msmq.dll stating that it is an assmebly not recognised by .NET. We were advised to use platform invocation services. Looks like a lot of work. My question is, is there a simpler way to do this.

    - TabControl page order Hello all, I am fighting a very aggravating problem in my VB.NET compact framework app. I have a tab control on a form. I set up the pages and put them in the order I like. It all works great. Then for some reason at random times Visual Studio decides to scramble the order! For the life of me I can't figure out a pattern. It is driving me bonkers! It all works fine - the tabs are just in a random order. I have no code anywhere that should change the order. I even tried going into the InitializeComponent routine and setting the order there but Visual Studio just comes along and wipes it out. Any suggestions??? Is there something I can put in a Page Load so I can set the order then?? Thanks in advance, Bob Tag: Big database application + Emulation Tag: 20050

    - .NET stops working after installing cyncware products Hi all, I am a .NET developer and have .NET applications I run on my Pocket PCs all the time. I recently downloaded software from a company called cyncware (I tried Time & Expenses and Pocket Converter). After installing these apps my .NET apps stop working. I mean nothing happens at all when I click on the application's icon. I also tried to run my own app from Visual Studio in debug mode. Visual Studio was unable to deploy to the device. This software must be deleting or modifying a very important file or changing the registry. I have not been able to identify the problem area. Cyncware products appear to be written in embedded Visual Basic because it installs the VB runtimes on my device. The only way to get .NET apps working again is to do a hard reset. Does anyone have products from this company and experience the same problem? Does anyone have a suggestion on where I can start to look for corruption? What files do Visual Studio need on the device to run in debug mode? Thanks Victor Tag: Big database application + Emulation Tag: 20047

    - SIP disabled after showing maximized form After showing a maximized form the SIP (InputPanel) on the calling form (which has a MainMenu) is not displayed when tapped. Putting on a breakpoint I notice that EnabledChanged for InputPanel1 is called 2 or 3 times with a value of 'Disabled' each time. There is no problem on the Emulator, just on the real device. Anyone know what's going on? Here's the code: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim form2m As New Form2 form2m.ShowDialog() End Sub Private Sub InputPanel1_EnabledChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles InputPanel1.EnabledChanged If InputPanel1.Enabled Then MsgBox("Enabled") Else MsgBox("Disabled") End If End Sub Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.WindowState = FormWindowState.Maximized End Sub TIA, Eric Tag: Big database application + Emulation Tag: 20043

    - Fast BMP loading (bypassing getPixel/setPixel) I know how to do this for saving (using a little low-level p/invoke trickery to get at the underlying HBITMAP data), but not sure how to do it for loading. Seems to come down to this issue How does one create a Bitmap object that contains a DIBSECTION internally without using the Bitmap(string) constructor? Using Bitmap(int,int) creates an object that uses DDBs instead, which the HBITMAP cannot be obtained, and hence is useless. Tag: Big database application + Emulation Tag: 20035

    - Scripting in .net CF Is it possible to evaluate expressions in VB.Net / VC#.net in the .net Compact Framework? We have a requirement to evaluate user-defined expressions on PocketPC devices. The expressions would contain references to methods/properties that are defined as well as built-in methods/properties. We currently do this with an eVB application with a home-grown expression evaluation dll and we need to port this application over to .net CF. Any information regarding this would be greatly appreciated. Robert Regnell Tag: Big database application + Emulation Tag: 20021

If I spawn the worker thread from the main application thread as shown below, where is the best place to put the code for the main application thread? I could fire it from a timer I guess but I want this code to run in a constant loop, and to start immediately. It needs no interaction from the user.

    - Some basic questions on using threads. Hi. I have 3 questions. For the short version: skip to the end of the post For those of you who has some time over: Here comes the long version of the questions, with some background. Iâ??ve done a program that sends a small message on the comport and then receives a large chunk of data. When Iâ??ve received my data I want to let the user start fiddling with it. But at the same time Iâ??d like to start a little code running in the background. This new code should send 4 small messages/second on the comport and receive a value each time, which Iâ??d like to display to the user while heâ??s fiddling with the other data. This seems to me like a task for multiple threads, right? (Havenâ??t used â??em beforeâ?¦) Since I need other tasks to run at the same time, I guess I canâ??t just use a timer. I had an idea of having a thread running a separate class with the background program. The thread could run the code and then sleep for 250 ms. Does that seem like the right way to go about? Although that wouldnâ??t make the 250 ms interval very accurate, since it would depend on the execution time of the code. How would I get the code to start running with exact interval? Another problem I have is that I need to call procedures in other classes. As far as I can understand this demands that the called sub is public and shared, but then I get problems since that sub often refers to instance members of that class (such as controls) and even properties of other instanced classes. I could perhaps try to make everything shared, but that doesnâ??t seem like a good way to solve things. Or is it the only way? This also applies to my â??background codeâ??, since Iâ??d like it to call a procedure in another class (the code handling communication with the comport). But can one do that with a separate thread? Do I need to rewrite that code inside the thread? In short: 1. How to run code at exact intervals (using threads)? 2. Is it possible to somehow use instanced members when calling a sub in another class? 3. Can a thread call procedures outside of its class? Iâ??d be very thankful for some help on any of my questions. /D Tag: Big database application + Emulation Tag: 20011

    - A simple custom control with design support I'm trying to make a Textbox with a FocusColor property...When the focus changes to the control, the backcolor must change automaticly to the color setted by the focusColor property. Very simple, the control works fine when creating it dynamicly from code. My aim is to add design functionality, so I can use it from the Visual Studio .Net toolbox. When I compile my code, no errors are reproted and Visual studio leaves a dll in the release directory. (cdaTextBox.dll) Even making a design time dll succeeded (design.cdaTextBox.dll). To make such a dll, I use the command line compiler csc.exe from within a batch file 'Build.bat'. Csc.exe does not report any errors. But, and this is my problem, when I try to add the control to the toolbox, Visual Studio fires an error: There are no components in 'C:\Program Files\Microsoft Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000 \Windows CE\Designer\design.cdaTextBox.dll' That can be placed on the toolbox. Can someone tell me what I have to change to my code to make it working?

    - SQL Server CE Design Question Hi I am writing an application that uses SQL Server CE with replication and C#. I have a few questions about the design of my database. I have created all my lookup tables to use integer identity primary keys and I was trying to use Guids as primary keys for the main tables that get used for adding/deleting records. Originally I had no problem by setting the PK of the table as a guid and no other properties, but this in some respects was not good enough as the replication engine of SQL Server 2000 the added the 'rowguid' column to my tables, making me think whatâ??s the point? I went back and had a look at why and saw the 'rowguid' columns had an default value of newid() and the rowGUID set to true. So I changed my tables to have these properties and everything seemed to work fine until in my app I wanted to add records. Firstly the automatically generated guid is a FK for other tables, so how do I find this value out. I used the cheap method of setting another (non PK) field to an unrealistic value then using the query SELECT * Table WHERE date = 1 or similar. Is there a better way Then after adding the record I need to update it and upon trying that I get the message "Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information". After some reading up on that message, which seems common for any OLE database, I tried adding in the necessary schema so the UpdateCommand will be generated by adding in the PrimaryKey value of the DataTable and then also my using the FillSchema() method of my DataAdapter. What I am really trying to ask is that am I going about this the right way. Since my application is going to be used on many devices I found that using a PK of type integer is not good enough. I then went to GUID's and had luck originally, however SQL Server added the rowguid column. So I changed the properties to what seemed to be correct and now I have a lot of problems. What is the recommended design Thanks In advance for any help! Tag: Big database application + Emulation Tag: 19964

Can anyone point me in the right direction? Thanks, Bob Tag: Big database application + Emulation Tag: 19934

    - Agressive disposing Hi, As Pocket PC's are (supposed to be) resource-restricted devices, I thought it would be wise to implement an agressive disposing strategy, i.e. add IDisposable to every class, and call Dispose() on everything. But I don't know exactly HOW agressive I need to be ;-) I.e.: - If I derive from Panel or Form, and a child controls (Me.Controls.Add...), do I need to remove and dispose those as well, or do Panels and Forms somehow dispose of their children themselves? - If I add objects to a Collection, do I need to enumerate over the collection and call Dispose() on every object, or should a Collection.Clear() accomplish the same thing? - If I add a handler (AddHandler obj.event, delegate), do I need to remove the handler myself when I want to dispose of the object? I assumed that all the above would be taken care of automatically by the garbage collector, but some of my objects start threads, and these threads are stopped in their Dispose() method (via a simple stopThreadRequested boolean flag). Yet if I quit my application, these threads appear to still be running, so it looks as if my Dispose() methods aren't called automatically...

    - Deploy content to specific folder Hi, In Visual Studio .NET 2003, my Solutions Explorer window, I have the following tree: MyProject |->img | |->MyImage1.bmp | |->MyImage2.bmp |->MyClass.vb However, if I deploy, everything is dumped in the same folder (MyProject). How do I tell VS to deploy the files with the folder structure intact? Regards, Elisa Tag: Big database application + Emulation Tag: 19930

    - PPC Power On Screen Hi all, I implemented code to try to turn on the screen in my app, since sometimes devices do not completely wake up when having an app run at a certain time. I did this with some code similar to what Peter provided on OpenNetCF site, attached below. This has worked great on my Ipaq2215, however, I had a user that upgraded PPC2002 to PPC2003 on an Ipaq3900. Apparently this doesn't work, as the app doesn't wake up when launched. I realize that this type of command is not universally supported, but I'd be surprised it didn't work on an Ipaq3900, so was thinking my implementation was wrong. Any feedback on anyone else with similar issues?

    - Reflection: does it work with CF? Hi wonder if the CF supports reflection. When I ask a simple Type.GetType("System.String").GetMethods I got uncomprensible errors. At runtime I get a NotSupportedException, on the debug window I get "Incorrect Parameter"... Also I cannot call Type.InvokeMember because it give the same errors. Some one experienced the same? Have I to renunce to Reflection? I'm testing it on the emulator 2002 and CF SP2. Thanks -- Math Parser : http://www.neodatatype.net Tag: Big database application + Emulation Tag: 19919

    - TypeLoadException Hi, I have developed a chess application and I have received 2 complaints: after installing .NET CF SP2 on a PPC 2002 (one is ipaq 1910 the other one I don't know) when they launch the game, they get this error chess.exe TypeLoadException Application::Run+0xf MainForm::Main+0xa I've asked them to install other .NET CF applications and they get the same error, so it seems there is a problem with .NET CF. I've asked them to reinstall SP2, to soft reset the PPC ... nothing. The only solution I can think of is to ask them to do a hard reset, however I wish I could find a less radical solution. Do you have any suggestions? Thanks, Valentin Iliescu Tag: Big database application + Emulation Tag: 19915

    - How to remove PerfCtr entries from Event Viewer? Had .NET development stuff installed but then uninstalled as part of tracking down other problems with system. Now, I get about 10 bitchy entries under Event Viewer>>Application related to CE.NET stuff being unable to find libraries, etc. Have tried a few of the things in the MSKB (running WMI dredger from cmd. line, renaming Library .DLL's) to get this stuff gone, to no avail.

    - What happened to John Kennedy? (Not JFK - the other one) Hi, all If you've been around the world of Windows CE for any length of time, you've probably encountered John Kennedy. He wrote one of my favourite PPC programs, Pocket Universe, as well as one of my favourite PPC games, TankZone. He started working for Microsoft a couple (?) of years ago, and wrote several instalments of the MSDN 'Two for the Road' column. Now his web site (www.stellarmetrics.com) is dead, and he hasn't written an MSDN column for over 6 months. Anyone know what's become of him?

    - How can I update my Emulator for VS.NET 2003 to a recent version? The version of the emulator that installs with my 2003 setup is 4.1.0 and does not have support for storage cards (there is no option for it under the menu in the emulator). I have downloaded the Microsoft Pocket PC 2003 SDK which gave me the 2003 pocket pc images but it did not upgrade my version of the emulator. I need to be able to emulate a storage card for my VS 2003 Compact Framework development. How can I upgrade my version of the emulator to one that supports storage card emulation and can still be launched directly from within Visual Studio 2003?

I have to start develop application in .NET technology. I consider VC# or
VB.

I've got experience in eMbedded technology: eVC i eVB. I'm using Pocket PC
Emulation (2000) to test all application. It's because I don't have to
inastall all DLL files, all ActiveX Controls when I want to test something.
I can simply copy files to and from emulation (using File Explorer).

I try to use Pocket PC 2002 emulation, but it wasn't easy and nice... It's
why:
1. problem with file coping to and from emulation (I have to use Windows CE
Remote File Viewer, which is not effective way...),
2. problem with DLL and ActiveX Controls - "Turn off Emulator" clear all of
then (Hard Reset).

I need some tips and tricks, which help me to develop (using Pocket PC 2003
/ Pocket PC 2002 Emulation) big application (data collection) with ActiveX
Controls, and which requires a few DLL libraries.

Thanks,

Tom
