I am trying to create a new MailAddress, the email is coming from Request Parameters, that is: Request.Params("fromEmail"). It is actually being sent from an android device through an http request.When I try to create a new MailAddress from this email, I get the error "The specified string is not in the form required for an e-mail address". When trying to create it directly, that it ma=new MailAddress("a@b.com") using the same coming string, it works, but creating it using ma=new MailAddress(Convert.ToString(Request.Params("fromEmail")) produces the error.

I'm making a multiple email sender, and whenever I try and send it. I get this error.

The following is my function. The error occurs when I try and set the from email address. It gives me an error: "The specified string is not in the form required for an e-mail address." But the email address is in a perfectly legitimate format (I changed the email so I don't get killed with web-crawlers pulling addresses, but it is the exact same format). Hope someone can see what I am obviously missing.

View 1 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?

Currently, to avoid errors from being thrown up due to invalid email addresses, I do the following:
Dim mailAddress As MailAddress
Try
mailAddress = New MailAddress("testing@invalid@email.com")
Catch ex As Exception
'Invalid email
End Try
However, rather than depending on Try..Catch, is there a way of validating that the email address will be 100% valid for the MailAddress type?I know there a plenty of regex functions out there for validating emails, but I'm looking for the function which the MailAddress type uses to validate its addresses.
I am using this regex string in one of my programs to validate email adresses: "^[a-z0-9._%+-]+@[a-z0-9.-]+.[a-z]{2,4}$". This works well for the most part, but I just found out that it doesn't catch an address like this ... "john.doe.@yahoo.com" ... where there's a "." right before the "@", which is invalid, so my program tries to send it & throws an exception. How to modify my regex string to catch this situation?

I'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

I am working on server side application of FB login.Having converted the example here:[URL]..To VB, and using System.Net.WebRequest.Create to retrieve the responses I am now able to get a text string including the access_token and the expiry time in the following format: access_token=ACCESS&expires=2577
Obviously I can split this into an array and split the parts to get the access_token But, on the FB Developers example above, they do it with PHP like so: $params['access_token'];Is there a VB.net way of doing this? This seems more reliable to me than teh aforementioned splitting idea, ie, if FB change the output format.

I'm using VB 2008 with .Net 3.5 and I want to check that a combo box has a selected value greater than 0 (default = Nothing Selected) before allowing the user to move off the tab page to another tab page.

View 3 RepliesI've written a program using Visual Studio 2008 Standard Edition in Visual Basic. It's a Windows Forms Application. The program is very simple, it just reads a directory of text files, parses the text and outputs another text file as .CSV file
for import into Excel. There's no user interaction required but it never displays the form and therefore the progress bar. If I put a GO button on the form and modify the program so that the subroutine that does the processing isn't called until the user clicks GO it shows the form and the progress bar etc. How can I make the program run at startup, show the form, show the progress bar and then pause for 10 seconds or so and then exit?
I am building a program where all the inputs (10) required from the user are asked on one form. Since it is not possible to let fields blank on the database, I would like to know how can I build an 'IF' saying that if all fields are full, then the database CAN save all the input. So that if there are any field blank, it won't save. I just dont know how to do the database condition. Thats all.

I'm attempting to use a product I've designed that stores 2 files on my web server space so I can access my stored data from anywhere. They are getting stored in the correct folder, but have several ___ (underscores) at the end of the file names.I'm sure it has to do with the way I bring back the stored string:My 2 variables are FILE1LOCATION (STRING) and FILE2LOCATION (STRING) They look just fine stored and recovered, but must not be.I recover them by the following code:
FileOpen(1, Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) & "myfoldermyprogmyinfo.dat", OpenMode.Binary)
FILE1LOCATION = " "
FileGet(1, FILELOCATION1_UPLOAD, 40)

This code should read the string "34,56,23,74,69" from a process's memory addresses (in this case notepad), right now it works but very slow and I think it even breaks somewhere. My problem is with the ReadProcessMemory function. I can't make it read an entire mbi.RegionSize into the buffer. I tried everything and now, it only reads 1 byte at a time until the mbi.RegionSize is finished then it checks if the text that was read contains the text I need to be found, then it goes to the next mbi.RegionSize. Now, even with notepad which is very small it still takes 10 seconds to find something and I intend to use it with a much bigger program, so it will take like forever. Another problem is that it only finds the string "34". If I put "34,5" it won't work.
