    - Determining whether sqlclient is installed, and installing it In my Windows CE.NET 4.0 application (written in VB.NET), I have two needs regarding sqlClient. 1. Determine whether sqlClient has been installed on the device. 2. If sqlClient has not been installed, then install it automatically. 2.a. From a startup batch file, can I have sqlClient.cab install itself silently during the device boot process? Can this be done, and if so, how? Thanks, Rod REarly@jswcoinc.com Tag: TreeView Tag: 26227

    - Deploying content files In my .NETCF application I have created an equivelent to an INI file. It's file type is .txt. I'm using it to read in application configuration settings as described in "The definitive Guide to the .NET Compact Framework". I just used VS2003.NET to deploy my application (which I have set to go to the Windows\Start Menu folder) and I have successfully deployed it on two new HP/IPAq devices. The .txt file shows up in my Program window and when I browse to the Windows\Start Menu folder the .txt file isn't there and my application is not displaying my "about box" info which is read from that file (although it's not throwing any errors either). How do you force content files to deploy to the same directory as the application? (using the Build, Deploy Solution method). Tag: TreeView Tag: 26221

    - Wierd ImageList behavior I've added five 41x41 pixel bitmaps to an ImageList. I then programmatically add different pictures from the imagelist into picture controls which too are 41x41. Setting the image propertyy for the pictureboxes works great at design time but during run time, the images are shrunken to 16x16 pixels before they appear. If I set the "shrink" they expand but are distorted as if they really are 16x16 pictures. Any idea what could be causing this? TIAM, Harry Tag: TreeView Tag: 26214

    - Form Text property getting overwritten by Start menu When setting the Text property of a form in either InitializeComponent or load event, the value will display upon first instantiation and showing of the form. If I hide the form and then show it again, the Text property value will not show - it gets overwritten by the Start menu label and is not visible in the Running Programs applet. I am forced to place the property-setting code in the Activated event to ensure that the value gets displayed on all showings of the form. Not a big deal, but a bit unexpected. I would have expected the Text property to 'persist' on subsequent calls to Show() regardless of where it was set in code. Comments? Tim Tag: TreeView Tag: 26183

    - XML Designer and Datasets. Hi I am creating a single XML file that shall have data as well as schema of my dataset. I am able to view the full XML source. But how can I use the XML Designer to modify the XML Schema? I can use the Designer to add rows to it. But in order to modify the schema I am requiring to create the .XSD file, which I dont want to. So if I want to make changes to the Schema in XML file, do I need to manually modify the XML file? Also even though my schema is present in seperate XSD file, a change in schema should be reflected in my data file(.XML File) which is not really happeneing. (E.G: If I change the name of field.) Therefore if I have say 1000 Records, then a simple single change in schema would result in manually changing 1000 rows...Is that true..??? Thanks Amit Tag: TreeView Tag: 26165

    - XML/user data... Hi all, I'd appreciate some feedback on persisting user-settings. In my app, I have 3 different XML files that are used to persist data. I'm going nuts to try and lower the load time in my app. Reading the XML files are not TOO bad, but I've done a few very simple benchmarks to get an idea as to where my bottleneck is (times are cumulative): Constructor of main form: several seconds (inherent of .NET apps) +0 Initialize component, load several objects: +2 Load all XML files: +5 Process all settings, load off-screen graphics: +6 Form_Load called, several other objects instantiated including background threads: +7 So this is bad -- 7 seconds until the Form_Load is complete from the time the constructor is first hit. If I load the app continously (say, without a reboot) I'll get a bit more favorable result: Constructor of main form: several seconds (inherent of .NET apps) +0 Initialize component, load several objects: +2 Load all XML files: +4 Process all settings, load off-screen graphics: +5 Form_Load finished, several other objects instantiated including background threads: +5 So on average, my app takes about 6 seconds after the constructor is hit. I can shave about 1.5 seconds by lazy-loading a few of my heavier objects which I'm already working on. Loading all the XML files takes just under 3 seconds on average, which is the biggest drain. I've tried reading the data: 1) Using the XMLTextReader, 2) Using the DOM to navigate to the settings, and 3) Loading the XML into a dataset. Using the XMLTextReader is (IMO) the crudest method, but the fastest, with times of 2.8 seconds, 3.8 seconds, and 4.5 seconds, respectively. I'm not using many controls at all, it's clear my heavy objects and XML is the burden. But what can I do about the XML load times? I'm open to any suggestions -- moving to a lightweight database, for example.... suggestions? Thanks, Brian Tag: TreeView Tag: 26153

    - [REPOST] - How to improve quality of GIF's in Toshiba e800 app Hi There, My Compact Framework app displays 240 x 180 .gif files on a PocketPC. On the e800 in normal resolution (240 x 320) the quality of the image display is conisderably worse than with previous QVGA PPCs (eg e740, iPaq etc). I understand this is due to the pixel doubling that is taking place, but when I tried using and shrinking a 480 x 360 version of the image using PictureBoxSizeMode.StretchImage it didn't improve the quality much, if at all. Is there some trick to restoring the image quality of a .gif file on the e800 to at least that of its predecessor devices? Will this problem be improved when the e800 is upgraded to Windows Mobile 2003 (2nd ed) ? Thank you... Robert Tag: TreeView Tag: 26137

    - CF Service Packs impacting registry auto start functionality? This is a question I posed to Jon Box, someone some of you might recognize. He then suggested I post my question on this group (which he refers to as "The Newsgroup") which I had been previously unaware of! My problem, in a nutshell, is this: After installing CF SP2 to fix one problem another problem has arisen that I cannot effeciently get around. To go slightly further, the new problem is about the registry loosing the ability to auto-start my application upon soft reset in order to keep the user from interacting with the operating system normally. Now, to go beyond the nutshell, I am trying to develop a Kiosk Mode system for mobile applications and part of its functionality was to add a path to itself in the registry (specifically, the Init key within HKEY_LOCAL_MACHINE) so that it would start automatically upon a soft reset. Under Service Pack 1 of the Compact Framework, this method worked wonderfully; the application would start itself even before the Start Menu and the ?desktop' (i.e. the Today Screen) was shown. But there was a problem: the button control did not support KeyDown, KeyPress or KeyUp events which another class of mine that handles key configuration used to handle input from the device's hardware buttons. Thankfully, this issue was solved in the Compact Framework's Service Pack 2; now all controls carry the key events and buttons can receive the focus and still process events from the hardware keys such as Calendar or Tasks (when the messages have been intercepted using the Game API). But another problem cropped up afterward: now the entry into the registry which specifies when my software loads during startup is being completely ignored; our software fails to load at all. I have tried this on the HP iPAQ running Windows Mobile 2003 and on an Intermec i700 running Pocket PC 2002. I have hard reset both of them and noticed that, upon deployment, the program will load but input will cease to work once a button control has received focus but, at this point, the program will load on startup. Then I will install the SP2 patch for the Compact Framework and input will work after a button control has received focus but the program will not load on soft reset. I will then uninstall SP2 and redeploy (the original version of the CF will load during deployment) and the original behavior returns. I am a little curious as to why the Service Pack of the Compact Framework would change the behavior of something which seems to be operating system specific rather than software development specific. I am able to confirm that my edit to the registry is made in both cases; it appears that under SP2 the registry is simply being ignored. Has anyone else had this problem? Are there any other solutions besides HKEY_LOCAL_MACHINE\Init that could help me here? We are aware that we may put the application or a shortcut to it inside the \Windows\Startup folder but, for that to work, the shell must load first and that reveals the start bar to the user (if only for a moment) and that's a drawback we would prefer to avoid. Any information would be helpful, and I'm glad to have found this place. Thanks a lot. Tristan Leonard Tag: TreeView Tag: 26129

    - Add emulator to device list in Visual Studio 2003 I am using Visual Studio 2003 to write an application for Windows Mobile 2003 platform (or whatever it's called this week). When I started working on this project, I had a "Pocket PC 2003 Emulator" device listed in the "Device Tools" dialog under Tools->Options. I tinkered quite a bit trying to get ActiveSync to work with the Emulator, to resolve some motherboard problems, etc., and to make a long story short, that option is no longer available. I still have the Window Mobile 2003 Emulator available on the machine, and I can lauch it manually, but it does not appear as a debugging option in Visual Studio. Can anyone tell me how I would go about re-adding the 2003 Emulator to the Device list? Where is that information stored? I've looked for it in the XML config files and in the Registry with no luck. I considered reinstalling the Pocket PC 2003 SDK, but I thought I'd ask here first to (hopefully) avoid taking any more steps backward. Thank you for any help. Jon P.S.

    - URLEncoding, WebClient, Access->SQLCe, SpecialFolders Hi, In porting a desktop app to the CompactFramework, we're doing OK on compatibility but we do wonder if folks have solutions for some of the missing things we need: 1. We need to post data to a Web site in a URLEncoded fashion. web.HTTPUtility seems missing. How do we do a URLEncode? This must be here somewhere? 2. We need to upload files to a Web server. On the desktop version, we used a modified version of some sample code in Help. The sample code uses the WebClient class which is missing in CF. Ideas? 3. System.Environment.GetFolderPath is used on the desktop app to know where to put user files (GetFolderPath(Environment.SpecialFolder.LocalApplicationData)) for example. Any idea what we should use instead? 4. What's the easiest way to port an entire Access (.mdb) database to a SQLCe file? I read the previous notes about InTheHand but our database will be very, very large so I'd rather use SQLCe. Also, does anyone have thoughts on relative file size and performance?

Therefore it is expected that when i add a new row into the dataset (using DataSet.Tables[0].AddRow()) with a same Column1 value, it should throw me some exception, but unluckily it is not. Instead it is adding the row with the same value and hence duplication of Column1 values. Where exactly is going wrong? The amusing thing is if I have a single file(MyXMLFileName.Xml) which have both Schema as well as data then it certainly give me an exception, but if I have two different files as I explained above, it doesnt throw exception.. Is there any reference site where i can get around this problem, or some samples for ready reference.. Please help.. thanks a lot Amit. Tag: TreeView Tag: 26079

    - Microsoft eBook Reader Does anyone know if the eBook Reader for PocketPC provides a way to hook into its internal event mechanisms? The only hint I have seen so far is that a Dictionary authoring SDK is available (presumably this lets you hook into the "Lookup" event). Also, is there any API to let you drive the application from external code (something more fine-grain than mentioned in "Call Microsoft Reader From a CF abb in VB") TIA Tag: TreeView Tag: 26056

    - PowerAwareApp question... Alex, I have a question for you on the PowerAwareApp code you've written. In the WaitForProc method, the last two lines: CloseHanlde(hQueue); CloseHanlde(m_hEvtQuit); Seem to always throw MissingMethodExceptions when exiting the app. Any ideas why? I was thinking that maybe the form was already disposed of at the time, or some other threading-related issue. Second: As you've written it out of the box, it works well for picking up states such as PowerOn. Do you know if it's possible to detect an "OFF_AC" state (such as taking the device out of the cradle)? If not, I can see that there's an unsupported NOTIFICATION_EVENT (with a value of 4) for CeRunAppAtEvent that can handle "on" or "off" AC power. I was thinking if the above weren't possible, I could perhaps use this somehow -- if the app is already running when CeRunAppAtEvent is fired, I know it just brings focus to the application; is it possible to capture a sender or otherwise have the app figure it why it was focused? Thank you again for your help, Brian Tag: TreeView Tag: 26041

    - creating for CF and Winforms I have a component that works great under Winforms, but I'd like to use it under CF as well. It's doing a little P/Invoke to use some APIs that are available in WinCE and Windows. What I'd like to do is have a single assembly that will run under Winforms and CF so my SmartDevice application can run on the PPC and the desktop. Is this possible? -- Floyd Burger Tag: TreeView Tag: 26026

    - Callback problem... Hi all... I'm having an issue trying to implement a callback. I've been working with Alex F. PowerAwareApp sample. I've modified it so that instead of opening the login form, I raise an event that the parent form can intercept. I can't get it to work (MissingMethodException) but I believe I know the cause, I just don't know how to fix it. In my case, my parent form is VB.NET, and the class is virtually unchanged from Alex's work, except for the addition of the delegate. In the class that handles the WaitForProc, et.al, I have code similar to (the EventDescription string in the event is simply to test that I can pass something back): public delegate void PowerStateChange(object sender, PowerStateEventArgs e); public class PowerStateEventArgs : EventArgs { public string EventDescription; public PowerStateEventArgs(string EventDescription) { this.EventDescription = EventDescription; } } In the class with WaitForProc, I have: public event PowerStateChange OnPowerStateChange; Then in the WaitThreadProc, assuming the condition is meant, I do the following: PowerStateEventArgs args = new PowerStateEventArgs("TESTONLY"); OnPowerStateChange(this, args); If I create a test form (called login) in C# that calls this powerstate class, all works fine by wiring up: login.OnPowerStateChange += new PowerStateChange(login_OnPowerStateChange); The IDE seems to do a good job at "filling in the blanks" and creating the method. But I can't get this to work in VB. What is the equivalent of that last line of code in my parent form such that my VB.NET form correctly gets the callback? Thanks, Brian Tag: TreeView Tag: 26019

    - Baffled: SHGetSpecialFolderLocation throws MissingMethodException Hi, I working on a very simple prototype to intercept file system change messages on my Pocket PC. When I use the SHGetSpecialFolderLocation function, I get a MissingMethodException. What am I doing wrong? If anybody has sample code how to receive fife system notifiations, tat would be even better.. Here's my code: [DllImport("shell32.dll")] private static extern uint SHGetSpecialFolderLocation(IntPtr hWnd, int nFolder, out IntPtr Pidl); public static IntPtr GetPidlFromFolderID(IntPtr hWnd, int Id) { IntPtr pIdl = IntPtr.Zero; uint myvalue = SHGetSpecialFolderLocation(hWnd, Id, out pIdl); } Thanks, michael Tag: TreeView Tag: 26009

    - "File Explorer"-like listbox (beginner) I'd really like to create a listbox that is similar to the one in the File Explorer application. It displays an icon in the first column and some text in columns 2 & 3. It should be as wide as the screen unless a vertical scroll bar is visible (then it should be as wide as the screen minus the scroll bar) I'm not even sure that the File Explorer is using a listview, but that's what it seems like. I don't need the extra controls at the top This style is used in many applications so I would assume it is possible without having to write my own custom controls, but I can't seem to figure it out. Any help would be great or if you know where I might find the answer, please point me to it. Thanks. Tag: TreeView Tag: 26007

When i check the Emulator in the Remove Programs section i don't see any on the Compact Framework installation. what should i do to make it work? what are the .cab files needed for the NET CF to work properly?

I am trying to build an interface that sort of looks like a drop-down menu in some webpages that is colorful and animated. I thought that a TreeView might be a starting point...

I was wondering if there is anyway I can change the TreeView appearance so that I can add labels, buttons or combo boxes as nodes, and also change the + and - signs to some other image.

Please point me to any resources that are available regarding this.

Thanks!

Intrinisc controls in CF are not really customizable. I suggest to build a
full user control instead
