int val = lstvRecordsCus.SelectedItems[0].SubItems[0];
The returned value is an int in a string datatype. I need the right hand side to return the value in int instead of string.
I tried Convert.ToInt32, it didn't work.
All the values that comes from SelectedItems[0].SubItems[0] is of type int.

i'm trying to sort a datatable using the typical select method*. The problem comes because the field is string defined but it's containing integer values.
With sql the problem will be solved just using something like:
select * from table order by to_number(field);
but of course it's not working properly with the method commented above (select method).

How can I change the parameter value from Interger to String.
Here below is the part of the code that creates problem; the constant "sqlStatement" is as string, but when the parameters "@ProdColor" read the value it returns an integer instead of the proper type which is a string. I have tried every ting like: CType(sqlStatement(splitItems(1)), string)
Or convert or parse, but it keeps returning the wrong type.
Const sqlStatement As String = "INSERT INTO ProductDetails (ProdID,ProdColor,ProdSize) VALUES"
If item.Contains(",") Then
splitItems = item.Split(",".ToCharArray)
cmd.Parameters.AddWithValue("@ProdID", SqlDBType.Int).Value = sqlStatement(splitItems(0))
cmd.Parameters.AddWithValue("@ProdColor", SqlDBType.NVarchar).Value = sqlStatement(splitItems(1))
cmd.Parameters.AddWithValue("@ProdSize", SqlDBType.NVarchar).Value = sqlStatement(splitItems(2))
I have a stringvariabel in a form I shall insert in a SQL database in a integer field. I try to convert it in the parameterlist:

but it only store the value 0 and not the value of the e.Record["UtstyrID)"])
txtAddress.Text = DB.ProfileDataset.Tables("tblCustomers").Rows.Item("Address").toString
The above code generated Option Strict On disallows implicit conversions from 'String' to 'Integer' error under the Item("Address") I don't know what i did wrong...
Just a bit of infor before we get to the code...

I have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.
