View 1 RepliesWe have several asp.net web applications we've built and we also want to embed them into various sharepoint pages. We need to have them look like standalone applications when viewed in their own pages, but also have them look like they fit within the sharepoint page when embedded. We are doing this currently with IFrames and it works ok, but I'm wondering if there is some sort of proxy web part where we can configure the web part to point to an existing web app and it will proxy the contents through from the web app into the sharepoint page removing the need for an IFrame. Possible?

When using SPWeb.GetCatalog(SPListTemplateType.WebPartCatalog), it returns an SPList which of course contains a SPListItemCollection of the web parts in the web part gallery. When looping through the items, is there any easy way to get properties of the web parts? Such as AllowClose, CatalogIconImageUrl, etc... I know I can probably accomplish this using the listItem.OpenBinaryStream etc and loading the xml of the .webpart file, but I wondered if there was an easier way to do this.

View 2 RepliesASP.NET 2.0 and COM Port Communication
I have a managed DLL which communicates with the devices attached on COM/Serial ports. The desktop Winforms application sends requests on ports and receives/stores data in memory. In Winforms app I have added a reference to DLL and I am using the methods. This works well. Now, there is a situation where I need to show this data from serial/com port on a web-page. And also users should be able to send requests to the ports using this DLL. I have made a web app in ASP.NET (2.0). Added a reference to the DLL. I am able to use this DLL, the DLL communicates on the COM upon button click on web-page and also the response is shown on web page. However I am not happy with the approach and strongly feel that this is a bad approach. Also the development server crashes after 3 -4 requests. What is the best approach in this scenario. If I use a windows service then how would my ASP.net app will communicate with the Weindows service.Or can this be easily done using WCF. I have not used WCF any time nor any of .net remoting technique.
Is it possible to build a windows application to send articles to a blog I have developed?
View 1 RepliesSo I am working on a project in ASP.NET MVC 2 with C#.I have a View with a file upload but this is a flash component (.swf).The result of the file upload (the storing of the file and processing of data in the database) is done in a HTTPHandler.I would like the HTTPHandler to send information to my active controller.
Is there a way to get the controller that was used to load the view? I'm having problems finding information about it online.
I'm running an ASP.NET WebService on IIS 6.0 that shows a lot of HTTP 500 (probably just exceptions from the WebService) inside the log at %systemroot%System32LogFilesW3SVC1 on a customers site.
Is it possible to log the content of those HTTP responses and there requests without modifying the WebService using IIS or a plug-in for IIS?
I thought of using Wireshark or Fiddler to sniff on the HTTP traffic but I would prefer to just turn on an option inside IIS to make him log the communication (this should not be to hard since it is logging the requested URLs anyway)
I have an ASP.NET app running on a webserver. A third party is created another app in PHP which needs to send data to my app for processing. Initially it was assumed that the PHP app would be deployed elsewhere so we agreed that the communication would occur over the internet via HTTP (over SSL). My app would simply use a generic handler (ashx) file to recieve the data and send confirmation back.
Now it seems that the PHP app might be deployed on the same machine as my app. I like the fact that using HTTP (as opposed to say direct database access), the PHP app needs to know nothing at all about how my app works. But using the public internet seems silly for communication between two apps on the same machine. If the PHP app simply used a localhost address, would this ensure that all the data stays within the machine? Is there a better way to do this?
I am create an iPhone app that needs to talk to a Windows C# app. The app will run as either a Service or Form Application.
What would be the best way to accomplish this? Ideally exposing a service-type architecture would be best as I don't need a stateful connection (stateless is fine in this case).
Can a WCF service hosted by my app using a form of TCP binding be consumed by my iPhone? Or can an app host using httpBinding without the aid of IIS or some other web server?
To guarantee optimal performance, aspnet_isapi uses asynchronous named pipes to forward requests to the worker process and to get responses. On the other hand, the worker process exploits synchronous pipes when it needs to query for information about the IIS environment (that is, server variables).
Does the worker process always uses "synchronous" named pipes? (Response to aspnet_isapi.dll would be asynchronous too, right?) Can the worker process talk directly to IIS or does it have to send a synchronous request to aspnet_isapi.dll to inquire about IIS environment etc.?
i built a web based task manager / scheduler using vb.net
i need to add a small communication part to it to allow users to send messages to each other.
below is my concept design. the question is: is this the correct way of building a simple communicator or do you have better ideas?
I've a project in C which acts as a server and accepts socket communication. The server project has multiple C files is an exe which accepts messages from the client program and responds accordingly. I've to write a Client program in C# which should open a socket communication and send a series of messages depending on the result of previous message sent.
Is it possible to send a message in such a way that it will call a function in one of the C file in the server project?
I am working on a project where I have to design a front end(on C#) and have to display the data coming from PLC.

3. What .dll file I have to add in my project.
I have a web service with several web methods, each web method requires client machine to send their MAC Address and the server will validate this client base on this information (if not valid then return error) before proceeding to further operations. The communication between client and server is HTTPS. I only have about 20 clients or so. The question is is my way of doing this right/secure or not? If not then is there any simple way to do this?

I am building a website, within a large intranet, that wraps and adds functionality to another site within the same intranet. I do not have access to the other site's source and they do not provide any api's for the functionality they provide. I need to, somehow, have my server-side code go to that site, fill in some forms, then press a submit button. Is this possible? If so, how can I accomplish this?
Note: I am working in asp.NET if that matters at all.
I have a local application which parses data. What i need is to develop a web interface to query statistics and set configurations for the application thats running at all times. Since I am the developer of both applications I have full access to both source.
My main goals here are:
- have a service or app running at all times on the webserver doing most of the work
- have a webUI which will connect to this app and display stats and make configurations
- service/app will be writen in C#
- WebUI will be written in asp or php
- the WebUI must be accessable through the web domain ie: http://server/TestApp on default port 80 were there are other web apps running already.
I know there are ways to do this using a specific port to communicate to eachother, but i would like to avoid this. What is the best way to communicate between these apps?
I've been tasked with writing a SP (Service Provider) for SAML v2.0 in ASP.NET, and I wonder the following;If a user logs in on the main SP for a service (where my SP becomes accessible for a user as an anchor/link, unless previously bookmarked), and then requests access to my SP, how should I handle their login?
They will have logged in and become authorized by the IdP on the main SP, but how will that SP tell my SP that the user is logged in? Will I have to send a new authorization request to the IdP to determine whether the user is logged in or should it be passed on as post data/redirect with a query string from the SP? I've read the technical overview as well as the basics, but they don't cover this part. I will contact the main SP and ask how to proceed, but I wanted to cover my bases first and see if there's a standard way on how to deal with this situation.

I am having a simple WCF service hosted in my website. I am using a console client to send and receive messages from the service. It works fine when I run the WCF web host in my local computer, but fails badly with the SecurityNegotiation exception "The caller was not authenticated by the service". It works fine if I use basicHttpBinding, but fails for wsDualHttpBinding which is required for duplex communication.All the source code for both (console) client & (web) server can be downloaded at:http://www.supernovaservices.com/downloads/WfcEventService.zipI have searched a lot and could not get a proper answer
