I use vb.net but if it is easier in c#, I am trying to use this layout in email component.
I have an existing WSDL which returns information to remote devices using SOAP. However, I'm writing a new app with Android which doesn't support SOAP so I can't use the existing WSDL and have had to code a new app which looks for a querystring from the Android app and returns the data in a JSON packet. I've coded the module which receives the data okay but I'm unsure how to send the data back in JSON forma

View 2 RepliesI am trying to search for a term on this site: [URL] and return the definition of the term to a RichTextBox. I can search for the term easily enough. My initial idea was to find a div class similar to every definition, and in the source returned from my WebRequest there is always the div class:
<div class="luna-Ent">
So for example, if you search the term "lol" and view the page source, the definition for that term is wrapped as follows:
<div class="luna-Ent">laughing out loud; laugh out loud: used as a response to something funny or as a follow-up to something said only as a joke.</div>
My problem is that I cannot split the string, which contains the entire text from this web response, leaving just the above. Which I would further split to leave just the definition.Every time I attempt to split the string I get a bogus result with randomly cut up words and nonsense. There is only one <div class="luna-Ent">, so I have no idea why this isn't working when it does with a simpler string such as "lol?55?44" which you would split using "?".Here is the code so far, please excuse the crappy variable names. I always structure my stuff like that when testing?

how it might be possible to only request the FileIO permission for the data directory created by clickonce?

Unfortunately, I don't know the directory when I build the project.
View 4 RepliesI have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

My Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.How can I get the regular key name working?
Visual example from the immediate window:I want to use:
? request.Form.Item("stationIdea")
but it won't work because the key is:
ctl00$content_innovation_body$stationIdea
as retrieved by
? request.Form.Keys("4")
so only this works:
? request.Form("ctl00$content_innovation_body$stationIdea")
is this there an equivalent to Exception.Data(in .Net 2.0) in .net 1.1

View 14 RepliesI am working with serial port communications. I have very fast and continuous data on my serial port. I have a program to read data from serial port. I have comport.Datareceived event in my program to receive data. Now, the problem is there is data going every 100ms to comport. Will my comport.DataReceived event will receive also with that fast? Now,let's say there is data on comport and if I don't read it what happens to the data? The problem I'm facing is my dataReceived event is getting very slow after some time.If I stop sending data to my com, still my datareceiving program is receiving. That means it is not as fast as sending data.If I keep sending data from 4 to 5 days and coz my datareceived event is not that fast as sending, I am getting data very slowly and some times I am getting MemoryOutofRange Exception.
