    - 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? This is the batchfile code (it runs well): C:\WINNT\Microsoft.NET\Framework\v1.1.4322\csc.exe /noconfig /define:NETCFDESIGNTIME /target:library /out:design.cdaTextBox.dll cdaTextBox.cs AssemblyInfo.cs /res:DatAction.Controls.cdaTextBox.bmp /r:"C:\Program Files\Microsoft Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows CE\Designer\System.CF.Design.dll" /r:"C:\Program Files\Microsoft Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows CE\Designer\System.CF.Windows.Forms.dll" /r:"C:\Program Files\Microsoft Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows CE\Designer\System.CF.Drawing.dll" /r:System.Windows.Forms.dll /r:System.Drawing.dll /r:System.dll /r:System.XML.dll /r:System.Data.dll /nowarn:1595 >z.txt This is My C# code: using System; using System.Data; using System.Drawing; using System.Windows.Forms; using System.IO; using System.ComponentModel; #if NETCFDESIGNTIME [assembly: System.CF.Design.RuntimeAssemblyAttribute("PictureButton, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null")] #endif namespace Company.Controls { class cdaTextBox: System.Windows.Forms.TextBox { #region "Private data members" private System.Drawing.Color mFocusColor = System.Drawing.Color.Blue; private System.Drawing.Color mFocusTextColor = System.Drawing.Color.Yellow; private System.Drawing.Color mOriginalColor; private System.Drawing.Color mOrinalTextColor; #endregion #region "Properties!" #if NETCFDESIGNTIME [ System.ComponentModel.Category("Colours"), System.ComponentModel.Description("This our colours") ] #endif public System.Drawing.Color FocusColor { get { return mFocusColor; } set { mFocusColor=value; } } #if NETCFDESIGNTIME [ System.ComponentModel.Category("Colours"), System.ComponentModel.Description("This our colours") ] #endif public System.Drawing.Color FocusTextColor { get { return mFocusTextColor; } set { mFocusTextColor=value; } } #endregion protected override void OnGotFocus(System.EventArgs e) { mOriginalColor = this.BackColor; mOrinalTextColor = this.ForeColor; this.BackColor = mFocusColor; this.ForeColor = mFocusTextColor; } protected override void OnLostFocus(System.EventArgs e) { this.BackColor = mOriginalColor; this.ForeColor = mOrinalTextColor; } } } Tag: How to use TCP/IP Sockets with a WLAN (PCMCIA Card) Tag: 20000

    - 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: How to use TCP/IP Sockets with a WLAN (PCMCIA Card) Tag: 19964

    - Data truncation?? Hi all, Everytime I enter data into a SQL CE database using a windows form, the entered data gets truncated. When I view it using the Query analyser, I only see 6 characters. This only happens with the nvarchar column types. Is the data really getting truncated or is the query analyser set to display only the first characters of the column?

    - XML XPath Query compact framework Hello all, Probably a really simple question, but I'm trying to write some code in VB.net using the compact framework, that will load in SQL statements from an XML file before passing them to a query processor. What are the best ways to do this? I've attached the xml file to give some context. I need a way of xpathing the relevant sql element out of the XML and returning it as a string. How are XPath node selections done in the CF? Is it supported in the xmlreader or xmldocument classes? Help! Also, if anyone knows a way in which I could use some xsl to transform the parameter values into the SQL I'd really appreciate hearing it!

    - 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...

    - 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?

    - 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.

    - 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?

    - Start program in background I'm using the coredll.dll function CreateProcess() to start a new process from my VB .NET app. This other app takes a few seconds to load, so I'd like to start it in the background when my program launches and then just bring it to the foreground when needed. Is there a way to start a process in the background? Or start the new process and then immediately bring my process to the foreground?

    - Development machine for CF w/kb and 640w screen I'm looking to buy a used handheld that will support WinCE 4.2 and the CF. I need a screen width of 640 and height of 240 or more. I need it for UI development since our target device is not yet available. It looks like Jornada's will not do the trick. Others? It appears the handheld market is going away with Windows Mobile 2003 being targeted at PocketPC form factor. Thanks, Mark Tag: How to use TCP/IP Sockets with a WLAN (PCMCIA Card) Tag: 19849

    - SMTP Server from PPC Hi I have an app using CF on PPC 2002. I am looking for way to provide support to my users for when they have problems. I am looking to have them push a button on their app and it will zip then email their SQL database to me. The problem is I need to install a default smtp server on their pda so they don't have to enter their own (which will probably be closed off so people can't spam off it). If you have other ideas I would be up for it. I though about FTP but I need to know who they are which email will allow for Thanks Aaron Tag: How to use TCP/IP Sockets with a WLAN (PCMCIA Card) Tag: 19843

    - SDAuthUtilDevice ?? I have a CE.NET device built with Platform Builder 4.2 it has CF and sdauthutildevice.exe embedded in the image. I have been able to succesfuly remotly debug a C# program before. I would start the sdauthutildevice app on the device then do the Tools->smart device authenication utility in VS type in the IP address of the device and it would connect and I could step and debug. Now all of a sudden I can't connect any more. I always get this error screen.. I can't figure out what happened. I am pretty sure I screwed up the PC side as I can connect and debug on another PC with its copy of VS. What is this strange file pubkey.blb ??? How can I repair???

Hi,

how can a use a TCP/IP Listener within a compact framework application, when
connected to a WLAN. In the compact framework there is the assembly
System.Net.IrDA, which has a listener object included, but when connected to
a WLAN via a pcmcia card, do I have to use the same .NET Class Library?

Thanks for help
Martina

Have you tried just setting up a TcpListener in the same way you would
in the desktop framework? That should work fine, I'd imagine.

Hi,

You would use the System.Net.Sockets namespace (and, probably, the TcpClient
and/or TcpListener classes).
