    - Redistribution of .net framework 2.0 I have created a *.cab file for my pocketpc application. I have also successfully created a *.msi installer for the use of installing the application from a desktop pc and then via active sync it installs the app onto my smartphone. This all works perfectly! I have one problem, i want the *.msi to check to see what version of framework is currently installed on the smartphone. If version 2.0 is not installed, I would like the *.msi to install framework 2.0 onto the smartphone, so the user does not have to go to microsoft's website, download the files and install it. I have looked over this article and it doesnt help me at all. MSDN Link Please help me with this situation if possible. Thanks in advance.

    - Webservice GPRS Connection Hi Guys, I know that by calling a webservice, the connection is automatically setup. Is it possible to force the call to use a specific connection, one that has been setup using the connection manager I would like to be able to control the connection and to close it after use. I have tried using connection manager to first set up a connection and then close it, but it seems that the call to use the webservice creates another connection. Is this correct Or does it grab the existing connection and say "hey, this is mine now" and have exclusive use of it Many thanks, Millicent.

Sombody know if the not correct use of "Timer" can create memory problem When I close the forms I'm setting: Timer.Enable = False Timer.Dispose() for all the Timer used.

    - C++ wrapping around C# Hello everyone, I've just developed a C# application for PocketPC and it works perfectly. What I would like to do know is to convert this app into ActiveX to embedded it in a website. I've been reading the forums and blogs these days and I found some info, but nowadays I'm not sure whether it is possible or not. Besides, according to what I read <a href =" http://blogs.msdn.com/iemobile/archive/2007/06/20/ie-mobile-support-of-activex.aspx"> here </a> each time a new user visit the website a CAB file has to be downloaded and installed...

    - Battery Backup Hi all, I know about the function to retrieve the GetSystemPowerStatus() using pinvoke function to retrieve the status of the current battery level, as low, high, etc. In the same way the Compact framework provides a class to perform this operations called SystemState.PowerBatteryStrength. Is there any way to query the Windows Mobile 5 to ask about if there any battery backup installed on the device using the pinvoke methodology, or even better using manage classes inside of the compact frameworkv 2.0 Thanks in advance. jpena@isthmusit.com IsthmusIT Costa Rica Inc Tag: Sidebar Gadget Development Help : Gadget Building Smart Device Development

    - Listbox not responding properly to two subsequent clicks Please help me! I haven't found anything regarding this problem on the internet. If you are using a listbox in .NET compact (only true for compact!) you'll notice sort of a delay between two subsequent clicks selecting different items. The selection does not update if you do this too fast - the click event gets lost. It's really awful having to wait between to clicks! The problem also is showing up with listviews in detail view. How can you avoid this behavior Note that it's not an performance issue since there are only 3 items in the listbox. Try it with the emulator by creating a project, putting a listbox in the form and hit run. Then select an item in the listbox and almost instantly switch to an other one (that is a common practice in case you hit the wrong item at first).

    - VB.NET WM 5 Alpha Blend function won't draw I am trying to use the WM5 AlphaBlend() function to add transparency to an image. I found this link that contains a great example in C#. http://blogs.msdn.com/chrislorton/archive/2006/04/07/570649.aspx#571734 When I download and run the C# example it works fine.

    - how to load dll file in smartphone? Hi all, I'm using C# to write the windows mobile 2003 application and deployed on the smartphone. I used the method [DllImport ("vam.dll")] public extern void detect(string xmlFile, string imgName); to import the dll into the application "Debug" folder. i call the dll funcion using detect("xmlFile", myImage); My application is to detect the region on the image file automatically on the desktop and it runs successfully on the desktop version. Now, i have to migrate my existing automatic detecion of region on desktop to the smartphone. I using the same method mentioned above, there is no compile error found. But, when i run on the smartphone, I get the error while running. The error is "NotSupported" Is it due to the dll problem If i remove the line where i call the dll function, it works fine. I've put the dll in the same folder of the application folder in smartphone. I cannot put the dll in CAB file.

    - resource assembly error - System_SR_ENU_wm.cab installed. I know this has been posted before but can anyone offer any advice on the ' An error message cannot be displayed because an optional resource assembly cannot be found' error other than installing 'System_SR_ENU_wm.cab' All advice I've seen is to install 'System_SR_ENU_wm.cab' but this is definately installed and I'm still getting the error (or rather lack of). I know the exception is a web exception but need to see the details to sort out the problem I have with my mobile application (WM5 on UK english device). The error is raised when the device calls a method on a web service. It works when the device is cradled but when not it starts the GPRS connection as it should but then errors. So I'm mainly after advice on how to get error messages displaying on the device when it's not cradled (System_SR_ENU_wm.cab already installed) though any advice on consuming web service also appreciated.

    - install root certificate on disk image using platform builder? I have a web service that my mobile devices connect to over SSL. Obviously, the root certificate needs to be installed in order for the communication to work properly. I've done a lot of poking around, and there are ways such as this to get me started, and I can do some fun ugly MFC calls to things like CertAddEncodedCertificateToStore to get this to work. However, I'm hoping there's an easier way. Here's my situation: I have two models of custom Windows CE devices -- one with a screen, and one without a screen. No solution can involve user intervention such as clicking on a certificate or installing it through Explorer, because that won't work on the screenless models. We have a custom disk image put on the devices during the manufacturing process. Ideally, I'd like this image to include the certificate pre-installed. Is there a way to find out what registry keys are created during certificate installation so that I can just put these in my disk image and have all my devices come out with the proper certificate pre-installed My poking around has revealed stuff in HKEY_LOCAL_MACHINE\Comm\Security\SystemCertificates\Root\Certificates containing keys with unreadable names (a GUID or some other naming scheme) with a value called Blob containing a bunch of data that is presumably the thumbnail value of a certificate or something similar. Alternatively, if one could point me to a purely command-line program that installs certificates, I can integrate that into the device initialization software. Finally, if anyone has a good code example for using the Cert* functions, I'd appreciate that, because I could integrate it directly into my software. But my preference would definitely be to somehow just add it to the disk image so that it comes preinstalled. It seems as though it would be possible, given that some root certificates already come preinstalled in Windows CE.

    - submission rejection: "vulnerable to malicious attacks" A gadget I constructed was recently rejected by the gallery with only this explanation: " Your gadget wasn't accepted because it looks like it could be vulnerable to malicious attacks. Go to the developer center for ideas about how to make your gadget more secure" I read in the recent thread titled "Something wrong with submission process" that some gadgets may be being arbitrarily rejected with this explanation. However, I'm not certain that is the case with my gadget and I'd like to at least follow all of the available security recommendations before I resubmit. This page: http://msdn2.microsoft.com/en-us/security/bb498012.aspx suggests validating and sanitizing any "untrusted data" using javascript functions which it provides. My gadget reads an rss feed from a trusted source but I guess any remote source is considered untrusted. My gadget creates an ActiveXObject and uses it to poulate an rss xml array. The javascript functions suggested in the above link clean and/or validate strings. My question: from a gallery approval standpoint, should I validate each string as it is parsed from the array, or must the array be somehow sanitized sooner than this And if so, how would that be done I'm not sure what the approvers are looking for but i want to cover the bases before I resubmit. If anyone else has experience with this issue, i would appreciate hearing thoughts on this. Here is the relavent (unsanitized) code from my gadget: Code Block function getRSS() { loading.innerText = "Connecting..."; rssObj = new ActiveXObject("Msxml2.XMLHTTP"); rssObj.open("GET", rssSource + " f=" + Math.random(), true); //random number added to dummy querystring to prevent reading file from cache rssObj.onreadystatechange = function() { if (rssObj.readyState === 4) { if (rssObj.status === 200) { loading.innerText = ""; rssXML = rssObj.responseXML; parseRSS(); if (chkConn) { clearInterval(chkConn); } } else { var chkConn; loading.innerText = "No connection"; chkConn = setInterval(getRSS, 30000); } } else { loading.innerText = "Connecting..."; } } rssObj.send(null); } function parseRSS() { start = 0; end = 5; rssItems = rssXML.getElementsByTagName("item"); rssTitle = null; rssDate = null; for (i=start; i<end; i++) { rssTitle = rssItems[i].firstChild.text; rssDate = rssItems[i].getElementsByTagName("pubDate"); rssDate = rssDate[0].text.split(" "); rssDate = rssDate[0] + " " + rssDate[1] + " " + rssDate[2] + " " + rssDate[3]; document.getElementById("cell" + (i)).innerHTML = '<div onClick=\"showFlyout(' + i + ');\">' + rssDate + '<div class="title">' + rssTitle + '</div></div>'; } } Thanks for any suggestions on how I can get this puppy approved.

    - Decrypt a text file using TripleDES Hi All, I need help. Does anyone know how to encrpt a text file using TripleDES I have tried some codes from the internet. Unfortunately, they doesn't work. Here are my codes: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Security.Cryptography; using System.IO; namespace ConvertKey { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void menuItem1_Click( object sender, EventArgs e) { Application .Exit(); } private void Form1_Load( object sender, EventArgs e) { try { // Create a new TripleDESCryptoServiceProvider object // to generate a key and initialization vector (IV). TripleDESCryptoServiceProvider tDESalg = new TripleDESCryptoServiceProvider (); // File to decrypt string FileName = "EnText.txt" ; // Decrypt the text from a file using the file name, key, and IV. string Final = DecryptTextFromFile(FileName, tDESalg.Key, tDESalg.IV); label1.Text = Final; } catch ( Exception h) { label1.Text = h.message ; } } public static string DecryptTextFromFile( String FileName, byte [] Key, byte [] IV) { try { // Open the specified file. FileStream fStream = File .Open(FileName, FileMode .Open); // Create a CryptoStream using the FileStream // and the passed key and initialization vector (IV). CryptoStream cStream = new CryptoStream (fStream, new TripleDESCryptoServiceProvider ().CreateDecryptor(Key, IV), CryptoStreamMode .Read); // Create a StreamReader using the CryptoStream. StreamReader sReader = new StreamReader (cStream); // Read the data from the stream // to decrypt it. string val = sReader.ReadLine(); // Close the streams and // close the file. sReader.Close(); cStream.Close(); fStream.Close(); // Return the string. return val; } catch ( CryptographicException e) { label2.Text = e.message; } catch ( UnauthorizedAccessException e) { label3.Text = e.message; } } } } EnText.txt is a text file containing some TripleDES encrypted text. By right, label1 should show some encrypted text. However, in my case, it shows nothing. Hope someone could clear my doubt. Many thanks in advance!

    - How do you diagnose a TypeLoadException with no additional details. How might I go about diagnosing a solution that once deployed, the program doesnt start but instead says "*******.exe - TypeLoadException" with no other info given on the error screen. The program deployed and started fine until just yesterday, then it started doing that every other deployment....now it consistently gives that error. What might I do to figure out whats going on Some info the solution has one main project, supported by two class libray projects in the same solution, one of which uses sqllite.net The main project uses OpenNetCF and OpenNetCF.windows.forms, and the two supporting class libraries, as well as a dll built by a seperate solution (a security library)....various other references all around of course, but mostly standard stuff. Debugging does nothing, as the error seems to occur before the program even starts.

Hi everybody,

I recently decided to create my own gadget. I did the tutorial of the great Gadget Academy

But I have some problem with what would have been the easiest step of the creation : "packaging"

Indeed I have tried to create my zip file "myGadget.zip" (which contains : all the common file : gadget.htm, gadget.xml, settings.htm, folder js, images and css) and then to rename it into "myGadget.Gadget". But when I want to install it windows Vista return me an error "This is not a valid gadget package."

Does somebody know why I have this error and how to solve it

Thanks a lot for your help.

Re: Sidebar Gadget Development Help : Gadget Building

JimNastiq

if one of your folder js,image or css is empty you should remove it or put a fake file in it

Re: Sidebar Gadget Development Help : Gadget Building

phydias

I thought it was the problem too, but it is not...

I check all my folders and put images and css in each one, my js folder has the "settings.js" file inside.

Do you have an other idea

Re: Sidebar Gadget Development Help : Gadget Building

JimNastiq

check closer to your gadget.xml file it could be this!

or if you make en-EN or fr-FR folders be sure of your vista version

Re: Sidebar Gadget Development Help : Gadget Building

Andy E

I've had this a few times as a freak occurrence. Have you tried re-packaging it a few times

Check the following, too:

* Make sure you're not right-clicking the root folder and choosing "Send To -> Compressed (zipped) folder" you actually need to go into your .gadget folder and select all the files, then click "Send To -> Compressed (zipped) folder".
* Are you using third party software to build your zip ie WinRAR, WinZip, Power Archiver etc. I'm not saying that these would be causing the problem but I wouldn't rule it out either.
* As mentioned, make sure none of the folders are empty.
* Validate your XML at http://www.w3.org

I thought of some more but they've gone now. That's what working with these damn things all the time does to you!
