How would you verify if an IP address resolves to a computer name correctly from a textbox?
View 6 RepliesI'm adding an email facility to my VS2008 (VB) project. I have the form and most of the code in place but am unsure about adding the detail to the textboxes. My data will come from an Sql datatable via a Stored Procedure. What I would like to do is use the autocomplete property of the recipients textbox so as to show the Display Name and the Email Address as is done in Outlook. Like John Smith <jsmith@*****>

View 4 RepliesI would like to know if there is a simple way to validate an e-mail address? I have seen many ways that appear to use functions but I would like to use something simple because currently my error control is done like this:
If txtEmail.Text = "" Then
ErrorProvider1.SetError(txtEmail, "You must enter your e-mail address.")
Else
ErrorProvider1.SetError(txtEmail, "")
Is there a way to use the same type of syntax but instead of checking if the textbox is empty, check if it a valid e-mail address? I know the regular expressions can be used, but how in this circumstance?
I would like to know is this possible.I have a simple form in vb2008 with a button and textbox when i press the button i would like textbox to display my default router ip address.
View 14 RepliesI was wondering how i would be able to validate a textbox for the E-MAIL address of a person. For example it cant have anything like "`#[]-=+->~| etc. it MUST have an @ and a .com or .co.uk at the end of the e-mail. anyway i was wondering how i would be able to program this when the user types into the textbox they cant put in any of the other symbols?and IF there is a missing @ or .com then the user should receive an error message telling them to make sure that they put them in.how would i program that on a button?

In html it's easy to get a button to get an file on your local hard drive but I can't seem to find or remember how to do it for a VB application (using Visual Basic 2010). What I would like is for the button to find a local directory, select it and then add the address to a textbox.
View 1 RepliesI work for a printshop that screenprints customized hats ,tees and a host of other stuff for a variety of small businesses. Being that we are a small business as well, we can't afford to mass ship catalogs to our clients, so I decided to build a catalog application/business card that can be emailed to them. The app is rep. specific, and after choosing which options suit them best using text fields and combo boxes, upon clicking submit, the customers' info is emailed to the rep.
To do this, I am trying to get a popup window that displays an email form with the 'mailto' address previously set, so it can't be altered and the info from the previous screen to be pasted in the body of the email. Upon clicking the confirm button, the mail is sent and the window is closed. I already have the code to copy the info from the textbox and combobox entries and paste it into the textbox in the next form, but getting the email form to be functional is appearing to be quite a feet.
I have to create a block of code that detects the Local IP address of connected adapter and returns it as string to a TextBox.

View 1 RepliesI'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean
vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

I have to make a basic program that: Create a program with a simple interface that
1. Asks the user type his/her email address into a textbox.
2. When the user clicks the "Evaluate Email Address" button, one of two message boxes pops up: "That is a valid email address!" with an "Information" icon, or "That is an invalid email address!" and on a second line, "Please retype your email address.", with an "Exclamation" icon
3. To be considered valid, the email address must -include an "@" symbol, and -it must end in either ".com", ".net", or ".org" or ".edu" (I don't know how to check a string and test if its last four characters end with any of these and make it say not valid email address. I think I might have to use a case statement)
I am trying to make a web browser for a school project... and I have a few questions...

(i know it seems like a ton of expectations mainly i would like the first 2 the third is not as important) So i dont know how to do any of that...
I also would like to know how to go about making new tabs on demand and not have a bunch of tabs just sitting there...
last question how do i go about making new windows not just for browser windows but, making something like firefoxes options window.. not necisarily to do that but just to make i guess another form pop up...

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
View 1 RepliesI want to run a FTP url in explorer. (Not in IE) What i want is some how when the button clicked the URL should appear in the address bar of the windows explorer.
This is because the ftp I access should be accessed in that way (By typing the url in the address bar of..lets say ..mycomputer window.)
I don't knw whether both do the same thing. But when I do I manually I could access the FTP by typing the URL in address bar in mycomputer(I think it is windows explorer) but not by typing it in the address bar of IE.

My users have a mixture of DHCP and static addresses so cannot limit the NIC to either of these connection types. We tend to have a 172.16.x.x IP range, so is there a way to modify the above function so that it will only return a 172.16.x.x address?
