| Worker Threads and Events (VIP replies) |
| microsoft.public.dotnet.languages.csharp |
| I'm working on a class that needs to be called from a windows form, do it's work, and then, show progress back to the main form. I'm well aware that worker threads need to call Invoke for updates to the main thread to be threadsafe. I want to make this worker class I'm writing a self contained assembly so that other's can drop it into their projects. My question is: How can I NOT force those imple... |

| wsdl.exe and Nillable Value Types (VIP replies) |
| microsoft.public.dotnet.framework.webservices |
| I am attempting to use wsdl.exe to generate a Web Service Client in C# from a valid WSDL file generated by Apache Axis. My application requires the ability to distinguish between an unspecified value and a specified value. For that reason, the WSDL that is generated by Apache Axis utilizes 'nillable "true"' to permit Web Services Clients to indicate a value or specify 'nil'. The problem I am havin... |

| Calling Web Services using AsyncCallback |
| Develop.com's DOTNET List |
| I found a workaround. It does seem to be because of a call on the UI thread. So what I'm doing now is: public void CallMethodResultCallbackProxy(IAsyncResult ar) { this.Invoke(new AsyncCallback(this.CallMethodResultCallback) new object[] { ar }); } And this works. But its gross. So somehow "Invoke" knows how to call the object on the UI thread. There has to be a way I can tell the original call to... |

| "Parallel" HttpWebRequests ? |
| microsoft.public.dotnet.general |

I am hitting multiple search engines and aggregating the data for the site visitor and I need to run them in parallel since I can't wait the time it would take to run 10 of these searches in serial as it would give the perception of a slow website to the end user. This will happen probably ... |

| A limitation (or an oversight) of the Stream class? |
| microsoft.public.dotnet.framework |
| Hello. Let me first start off by saying that I'm porting a PC to mainframe session handling service that I wrote in C over to C# and .NET. I've modified the design of the service to mainframe session handling code to take advantage of .NET Streams. Unfortunately, I've recently come to the conclusion that there may have been an oversight made in the definition of the abstract Stream class. The asyn... |

| Access web page after asynch callback |

In the example (code listed below), my callback routine has two problems: 1. It runs TWICE; and 2. While it seems to update the web page controls, the results never show up on the page. I am using delegates per a couple of examples I found on MSDN and elsewhere. Wh... |

| Any reason for an enabled timer not to fire or count down? |
| microsoft.public.dotnet.languages.vb |
| I have a timer on a form. It isn't firing at all. I know that the timer is enabled, and that the interval is low (4000, which should be 4 seconds). To ensure the timer wasn't being inadvertantly reset I put some extra code in the subs that enable and disable the timer. They fire as expected. To test this I added a second timer with a 1 second interval. The event for this time would output the enab... |
