Could Not Establish Secure Channel For SSL/TLS For SOAP Call?
Oct 20, 2010
Our core server is calling out to a soap web service over https on a number of different servers to confirm that a transaction has completed.The code is dotnet 3.5 (vb) and works for the various callback services we have set up until we just moved a new one into production and it is refusing to communicate, giving the following error:Unhandled Exception: System.ServiceModel.Security.SecurityNegotiationException:Could not establish secure channel for SSL/TLS with authority -> System.Net.WebException: The request washe case here.

This is my first time using SOAP with anything. I have an interesting situation, I have to send query's via soap to a secure server and get a response back and then import the response into a database. I have the connection to the secure server figured out and importing the returned xml figured out. I followed examples however I get nothing back in the service windows from the remote web site.
Here is my vb.net code with the soap request inside:
Imports System.Net
Imports System.Security.Cryptography.X509Certificates
Imports System.IO
Imports System
Imports System.Text
Imports System.Data
[Code] .....

I wrote a soap service in PHP using nusoap. It works fine with the test client I wrote in PHP, however, our customer wrote his client in vb.net and it is not working. There are no errors that I see, but the service is not parsing his requests properly.
I am letting nusoap generate the WSDL, and it looks fine. If I compare a message that I send in to one of his messages, I do see a few differences in the envelope, but I'm not sure if the problem is on my end or his.

I am architecting a program that I need some help on. I need to have a "watcher" program that will sit on a server and monitor a SQL Server. At configured intervals, the watcher will run a query on the server and create a dataset of information I want to share to any clients that are listening. I am looking at WCF Peer channel but all I can see is peer to peer chat and most of the examples I have seen are partial examples. I have looked at the example program from Microsoft but I am still a bit confused. The listener programs will receive the dataset of values from the watcher and filter the data at the local level and display the data they need and display it to the end user. I don't know if a TCP client/server would be a better solution, but the dataset may contain up to 10,000 rows of data. From what I read the WCF Peer channel will transmit at 50 mbps and should handle this load. My other option is a server/client architecture using TCP spawning a new thread for each request. Does anyone have any good examples, or articles about WCF and VB that they can point me to?

I've got a micro controller with 4 channel ADC that I want to make a program for. It will be for data logging. I want to take each channel and display it in 4 textboxes to begin with.Later I like to do some conversions of the data to show temperature , use a lookup table and a few other things in each of these boxes, but at first I'd just like to concentrate on getting the data split into each box.The chip output is 8 bytes . The first two are the channel select and the next two is the data. Output of the chip is in ASCII. I don't want to send to the chip, just receive.If I view the output in decimal I get 1xx 2xx 3xx 4xx (xx being the data to display).

Could I subscribe to the _proxy.InnerChannel.Faulted and do that clean up there?

url...But what I'm looking for is just see if any alpha (0-254) is used in at least one of the pixels. Would the Bitmap.Lockbits and BitmapData method be the most efficient (speedy?) or is there another way. I've tried toying around with ColorPalette and the Alpha flag, but never could figure it out (and even if it is a way to check to see if the alpha channel is used at all).

I am developing a COM Add-in using VB.NET in Visual Studio 2008 Pro for Outlook 2003 and am having trouble assigning images to custom toolbar buttons. In a nutshell, I am having to convert from an Icon type to a stdole.IPictureDisp type so that I can assign my buttons a picture. The picture displays, but it loses the Alpha channel and the background is no longer transparent. I can verify that before the conversion to IPictureDisp object, that the PixelFormat property is set to Format32bppArgb (2498570). I am using a coding technique suggested here:[URL]. For C# users, this link [URL] shows how to modify the IPictureDisp one pixel at a time and rebuild the transparency, but I can't find similar functions in VB.NET...

I just can't seem to establish a connection between my two P2P applications over the internet(LAN works perfectly fine).
I have tried the following.
- Disabling Firewall
- Changing Port
The only way I can establish a connection is if I'm connecting to the same computer using the universal IP or the local. Does anyone have a fix for this? Oh and here is the error that I receive when trying to connect over the internet:
System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 255.255.255.255:8787

I'm designing a web service in ASP.NET and VS2008, and am using typed datasets for retrieving table data. These work well and establish their own connections through their associated TableAdapter objects. Edit: I'm using VB, BTW!I am now attempting to run a custom SQL string using a DataAdapter and a Command object, however I need to reference a Connection object in order for the Command to work. What is the best way to handle this?hould I:a) Create a global connection object using Global.asax, retrieving the connection string from web.config? (I've been trying that one already, with not much success)b) Create a class-level connection object using the InitialiseComponent method, also retrieving the ConnectionString from web.config?c) Retrieve a Connection from one of the TableAdapters that I've already created in my typed DataSets?d) Something else I haven't thought of yet?

i have created a control as above, this control allows me to import a png with alpha channel and random shape. and then it can display on top of any other control, i.e. textbox, picturebox,etc. and the background should always show what right under it, instead of just show its parent control. it worked if it's static mode, ie stand still in the form. but when i tried to drag/move it, the control wouldn't render itself properly,and also goes underneath other controls.

I want to start a new project on PC and Mobile Phone. But i'm still have so many question about the communication between PC and Mobile.
My project List:
1) My idea is establish a connection between PC and Mobile through IP address in first, but my question is 'How to do it' ? izit same like PC to PC by using Winsock open a port to access? i'm using VB.Net 2005 for PC and Net60 for mobile.
2)My mobile phone Nokia 6220 Symbian OS is support GPRS/3G. Since the GPRS/3G can connect to the internet, izit means mobile itself have a IP address and service provider in order to surf the web? So, can i connect my mobile phone to PC through this gateway?

I need to write a program that uses constants to establish the base pay, the quota, and the commission rate. The Pay menu item calculates and displays the commission and the total pay for that person. However, if there is no commission, do not display the commission amount (do not display a zero-commission amount).
Write a function procedure to calculate the commission. The function must compare sales to the quota. when the sales are equal to or greater than the quota, calculate the commission by multiplying sales by the commission rate. Format the dollar amounts to two decimal places; do not display a dollar sign.
The summary menu item displays a message box that holds total sales, total commission, and total pay for all salesperson. Display the number with two decimal places and dollar signs.
the Clear menu item clears the name, sales, and pay for the current employee and then resets the focus.
The Color and Font menu items should change the color and font of the information displayed in the total pay text box. Use a message box to display the program name and your name as programmer for the about option on the Help menu.
[code...]
So the issue is when I push calculate and summary, the total sales comes up, but not the total commission or total pay. Also, the color only changes to blue and that is it. I am not sure how to get the color or the font menu choices to be able to be choosen by the user. Is that possibile?
