So how does one turn SSL on in System.Net.Sockets.TcpClient with VB.NET code?
Turning it on in System.Net.Mail.SmtpClient is easy, you set the .EnableSsl property. I cannot find a corresponding property in TcpClient. It's probably buried somewhere.
I have a .Net program that has to run on a cluster of server 2008. To find out the right IP I resolve the dns by GetHostEntry(VarDefinedInfConfig).AddressList(0)
but when I am converting my old code (this code picks the wrong IP) dns.GetHostName().AddressList(0) => this returns a virtual IP and not the right one.So I changed my TcpListener to (dns is parameter from config)Dim listener As TcpListener = New TcpListener(New IPEndPoint(Net.Dns.GetHostEntry(dns).AddressList(0), 8001))
listener.Start()

We have an application that is installed and runs just fine on Vista. Our users are requiring a change to our application in order to change the system time on their PC. The code to change the time is as follows:
Private Sub UpdatePCDate()
Dim _ServerTime As Date = GetServerDate()
Dim _offset As Integer = TimeZone.CurrentTimeZone.GetUtcOffset(_ServerTime).Hours
[Code].....
When this code executes, it bombs because of UAC. How can we modify our program to display the message similar to when they try to change the system time via the Control Panel. That is, it warns them that something is about to happen that requires their permission.

I am enrolled in a class in Visual Basic 2008. I wanted to drop the class, but it is too late. Now, I am stuck with this project that the professor assigned and it's due this Thursday. Anyway, how do I do this: The credit card number TextBox control is dynamically enabled/disabled depending on the choice of payment type? And did I do the newOrderButton correctly (see code below)? This is also the clear button. And is there a way to do a reset Form? Sorry for that many questions. I am really lost right now because there is a lot to do in this project and I don't even have a clue of how I am going to finish this project.
Private Sub newOrderButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles newOrderButton.Click
' clears all the information that is displayed and start over

View 4 RepliesI have 4 forms. I have a button on form2 that when pressed, I want it to enable a button on form1. What I've tried is this:
Code:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Form1.Button3.Enabled
End Sub
But its telling me that the property access must assign to the property or use it's value.
I attached a picture of how my project should look and what the labels are. There are a total of 12 books and 4 different age groups. In each age group there are 3 books. There is also a previous and next books button which will show the next book in that age group. I want to make it so that previous button is disabled when it is on the first book of each age group and so that the next book button is disabled when it is at the last book. The only issue that I am having is that after the button is disabled it is not enabled again after. Here is my full code for this part as of now. As you can see I made it so that everytime I click on a new age group the previous button is disabled initially.
I took some unnecessary code out of here because I don't want anyone from my class finding this and coping all of my work.
Public Class BookInfoForm
' use this array to display information in this form
Private books(,) As BookInfo = getBooks()

I am creating a dedicated browser to be used exclusively on a single program located on my hard drive. Security is not a concern as the webbrowser URL will be set to the program's default web page path with no navigation options for going online. The program utilizes dynamic web pages with powerful search capabilities that require ActiveX controls. When I run my browser application, I get a series of security warning boxes stating:
Internet Explorer
An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?
Yes No
Clicking "Yes" allows me to continue and the program features work, but the recurrent warning message boxes are annoying. The default "script errors suppressed" property of the webbrowser control is "false." If I change it to "true" I don't get the security warning boxes but some of the search features on the web pages with ActiveX controls don't work properly.
Is there a way to programmatically enable ActiveX controls in the webbrowser control so that I can set the "script errors suppressed" property to "true" (hence no security warning message boxes) and still allow the ActiveX features to work properly? Or, set the "script errors suppressed" property to "false" and have my program automatically activate the "Yes" button each time a security warning message box is called by Internet Explorer? The goal is to get the ActiveX controls to work in webbrowser without having to click through the warnings.
when I got home to try out the method in the above post in my real application things did not work out.The big difference is that my main form is a MDI. When I open my edit form, it's mdiparent is set to the main form. When I click 'edit' and then disable "me" the entire application goes modal.I was expecting only the MDI child to go disabled, not the whole application..Basically, I want only the MDI child window that opens it's "edit" dialog to go disabled..
View 1 Repliesis there a setting in the options somewhere that makes the shortcut keys show with the underline when you run the application? In the designer it shows the shortcut keys with the underline but when i run the application it does not show the underline indicating a shortcut key. Now if I push the alt key they show up and they work fine just wondering if there is a setting somewhere that will make them show the underline automatically when you run the application so an inexperienced user knows that there are shortcut keys available?

I'm using VB.net 2005 to input data from a database application into Excel files.I un-protect the sheets, input data into specific cells using named ranges, then re-protect the sheets.
This has worked fine so far, up until I ran into a file that is protected with auto-filtering enabled. When I re-protect the sheets, I can't seem to protect it while allowing the use of autofilter dropdowns. The dropdown arrows for the autofilter are greyed out and disabled.
Using the following code to re-protect the sheets after inputting the data.

works fine. The sheet is protected and I can use the autofilter drop downs. But when I use that same code in my VB.net project, the drop downs are not enabled.
During development, we usually use localhost as the hostname, like the following
Dim serverListener As New TcpClient("localhost", 8585)
I want the user to be able to enter their IP address via a TextBox instead, like
Dim serverListener As New TcpClient(textbox1.text, 8585)
However, this is not working for me.
I am creating an application that will be talking over the LAN (and eventually, WAN) which uses the Tcplistener and Tcpclient objects.Now, I have this working absolutely fine locally using the loopack address although when I change the IP of the listener to 0.0.0.0 (listening for all IPs) and the IP in the client application, to the IP of the server, it throws an exception when connecting. The client says something along the lines of the the server has rejected the incoming connection. So i disabled all firewalls temporarily but I still have the problem.I have ran netstat on the server which clearly shows that it is listening for an incoming connection on 0.0.0.0. [code]
View 5 RepliesI'm working on a winform which contains several controls like textboxes, radio buttons, datagridviews... All of these controls have been added to a main group box called gbDataEntry. My problem is when the user is seeing the form, I set gbDataEntry.Enabled = False but I want to enable some controls like DataGridviews so the user can scroll them. After disabling gbDataGridview I set DataGridView1.Enabled = True but it seems that the datagridview does not respond to this line. Why?
