I am working on a program that has a combobox that gives you selections for email address endings, but when I try to enter it in as part of the final email address get an error. Here is my
mail.To.Add(TextBox1.Text(ComboBox1.Text))
When I click debug, it give me this error. "Conversion from string "@txt.att.net" to type 'Integer' is not valid."
"@txt.att.net" is the value of the combobox selection.
In the end it should be something like: "anything@txt.att.net"
(Textbox1.text = "Anything" & the current ComboBox1.text selection = "@txt.att.net")
a user will enter a number, n, which ranges from 1 to 30. they will also enter a "P" or an "S" (sum or product). depending on which was selected, it will calculate the sum or product of the numbers from 1 to n.i'm having a conversion error on line 5 stating "Conversion from string "S" to type 'Double' is not valid."

View 3 RepliesWe are running .NET 2.0 ASMX web services on Windows 2003 server on IIS 6.0. We have migrated a legacy VB 6.0 application to .NET 2.0 application using VB.NET. CDATE function is used at many places and we did not replace that with .NET equivalent date functions. After migration, code was working fine for many years.Recently, we have started encountering issues on our production servers where the below code fails:
CDATE("11 Jul 2011 21:10:27")
Error: Conversion from string "11 Jul 2011 21:10:27" to type 'Date' is not valid."If we perform an iisreset, the same code starts working fine. Could this be due to some recent patch for Windows server/ .NET patch?
how I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now

I developed a VB.NET application in visual studio 2008. I am beginning to test it on user's machines. For many users, it works just fine. For some users they get an exception error:
System.InvalidCastException: Conversion from string "0" to type 'Double' is not valid. ---> System.FormatException: Input string was not in a correct format.
I developed the application with Option Strict ON. The line of code causing this issue is below:
Dim x as double
x=cdbl(y) 'where y = "0"
Another error the same problem-users are seeing is: System.FormatException: Input string was not in a correct format.
The line of code causing this error is
Dim x as double
Dim tempStr as string
x = Convert.ToDouble(tempStr) 'where tempStr="0"
The interesting thing here is that it works fine on my computer and fine on several test-users' computers. I compared the .NET framework between a working user and a non-working user and it was exactly the same. It seems to be getting hung up on string issues.

I am importing an Excel spreadsheet, turning it into a dataset and inserting the results into SQL Server (only 100 rows).

How can I add a check to the Dim F As Date = CDate(row(5)) to handle a null?
