WCF / ASMX :: Calling A WebService On TextChange Of TextBox?
Dec 10, 2010
Well i dont have an error but would like to get some guidance on this. I have a webservice that calls a class. The Class translates numbers to figures i.e. 4000 will return a string 'Four Thousand Shillings'. So what i actually want is how i can do my processing
backwards so that in the service i call the class's method to return a string so that i put the results on a Text property of a Label Control while i type each figure in a TextBox Control.
i.e. if i type 4 in my text box, i should see 'Four in my label', then 40 will return 'Fourty Shillings', then 400 will return 'Four hundred'

I need to call a Java webservice from my ASP.Net application. The webservice uses Java Key Store (JKS) certificate. Could some one help me with how I could do this? As a side note, when I try to add Web Reference or Service Reference to my Visual Studio project by providing the WSDL, Visual Studio always crashes.

I have almost the same problem as you have described in [URL] service. I have a asp.net webservice that calls a WCF service. On my development machine this is working fine. But if i deploy my ASP.net Webservice it is not working. Both the ASP Webservice en WCF service needs my cridentials. How did you solved your problem. In the logging of the WCF service I see that my credentials is not passing to WCF.

I'm trying to call an asp.net webservice from the same project it's in:
[MethodImpl(MethodImplOptions.Synchronized)]
public static void OnFileCreated(object source, FileSystemEventArgs e) {
trackdata_analyse rWebAnalyse = new trackdata_analyse();
rWebAnalyse.Analyse(@"pending" + e.Name, "YOUNIVATE");
}
However i always get the following "HttpContext is not available. This class can only be used in the context of an ASP.NET request." when calling Server.MapPath from the webservice:
[WebMethod]
public int Analyse(string fileName, string PARSING_MODULE){
int nRecords;
TrackSession rTrackSession = new TrackSession() ;
string filePath = Server.MapPath(@"..data") + fileName;
Do i have to add the WebReference instead, though the webservice is in the same project?

I have spent a couple of days on this one. I have an ASP.NET website that has Linkbuttons on
the Default.aspx page.. I added a WebService to the Website because later on the WebService will
subscribe to a Provider(Feed) of News, Sports and Weather and things like that. So when a Linkbutton
on the Default.aspx page is clicked it will connect to the link in the WebService which will load the News,
Sports or Weather onto the Default.aspx web page.
The problem is I can't get the LinkButton to execute the Link in the WebService. The link will call the page up
to where you see all of the Web References. But then if you want to execute one of those references you
have to click its link and the Invoke button that will follow. My questioh is how can the link on my Default.aspx
page execute the link in the WebService. Now I changed the LinkButton into an <a href> but I still can't execute
the link in the WebServices. I always use www.Microsoft.com as the link when testing and I wasn't sure about the return type
so I put "void" for an HTTPRequest, so below is the link from the Default.aspx web page and below that is he asmx file:
