ResponseSubmittedEventArgs.Response - strange characters

[Guest]

Hi!

I have followed the MSDN documentation to implement use of the
"Notification"-class to let the user enter data.

http://msdn2.microsoft.com/en-us/library/microsoft.windowsce.forms.notification(vs.80).aspx

Private Sub ctlNotification_ResponseSubmitted(ByVal sender As System.Object,
ByVal e As Microsoft.WindowsCE.Forms.ResponseSubmittedEventArgs) Handles
ctlNotification.ResponseSubmitted

When I interprete the e.Response some characters has been replaced by the
system, and that is really annoying.

E g the string "A B/C" becomes "A+B%2FC".
The space character has been replaced with a "+"
And the "/" character has been replaced with the string "%2FC".

How to prevent this distortion of the entered string?
Or is there a built in method for restoring the string?

Best regards
Benjamin,

The return string you are providing is html encoded. you can perform a html
decode on the string to get the original string.

Hi Rick!

Do you mean the "HttpUtility.HtmlDecode"-method?

Thanks for the suggestion, but the HttpUtility Class is not supported by the
".NET Compact Framework." (I am building a smart client using "Windows Mobile
5.0 Pocket PC SDK" in Visual Studio 2005.)

I am seeking an equivalent method that is supported...

Yes, give that a try and see if the results are what you expected.

Sorry,
forgot that CF did not contain this class. I'll look some more, but my may
need to write a class that performs the html decoding for you. You can
search Google for decoding requirements.

Hi!

Ok, so everybody that uses HTML code in the Notification-class needs to
"HTML Decode" the return string with a user created function (as I have
understood from previous posts). But this must be a common task, though I do
not find any obvious match on google. Any hint?

It's a pretty simple and well-documented process on how HTML encoding works.
It's largely just a hex replacement. For example here's one from a project
I have (I wouldn't say it's complete or the best way to go, but it works and
gives you an idea how it works):

public static string HTMLDecode(string safeURL)
{
if (safeURL == null) return null;

string url = safeURL;
url = url.Replace('+', ' ');
url = url.Replace("%20", " ");
url = url.Replace("%21", "!");
url = url.Replace("%22", "\"");
url = url.Replace("%23", "#");
url = url.Replace("%24", "$");
url = url.Replace("%25", "%");
url = url.Replace("%26", "&");
url = url.Replace("%27", "'");
url = url.Replace("%28", "(");
url = url.Replace("%29", ")");
url = url.Replace("%2a", "*");
url = url.Replace("%2b", "+");
url = url.Replace("%2c", ",");
url = url.Replace("%2d", "-");
url = url.Replace("%2e", ".");
url = url.Replace("%2f", "/");
url = url.Replace("%2A", "*");
url = url.Replace("%2B", "+");
url = url.Replace("%2C", ",");
url = url.Replace("%2D", "-");
url = url.Replace("%2E", ".");
url = url.Replace("%2F", "/");
url = url.Replace("%3c", "<");
url = url.Replace("%3d", "=");
url = url.Replace("%3e", ">");
url = url.Replace("%3f", "?");
url = url.Replace("%3C", "<");
url = url.Replace("%3D", "=");
url = url.Replace("%3E", ">");
url = url.Replace("%3F", "?");
url = url.Replace("%40", "@");

return url;
}
