I have the option of having a VB function to re-format a file within my website or to have the program given to my 12 member (only) user group to re-format. Which is better ??If its not part of the website, each of the 12 member user group will have the VB.exe code to run that generate the file and it can be uploaded to the website.If the webiste runs its own vb code, it will require the data to be upload and then generate the file.

I've completed the 22 first tutorials of the data access tutorials, and now I'm trying to apply these techniques to a project I started myself.But i'm stuck trying to replace an id by its value from another table, so I want to show all information about a car ("wagen") , but instead of showing "1" as driver ("chauffeur") I want to show his name.I've written this querry for the "wagen" table in the dal

When i write the following lines then i get an error like..
Input string was not in a correct format.

As far as I can tell, I've got the input string in an acceptable format (It's pulling a number that is the value from the Agent dropdownlist) and I'm even having the code convert the value to Int32. The database column is set to "int" and the DAL and BLL both reinforce this. Am I missing something? I can't post everything because the sensitive nature of some of the code, but here's some of what I've got. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Here's the code from the BLL

In my application i write the code like this
byte[] byt = new byte[Convert.ToSbyte(textbox1.Text)];
it is giving the error that input string was not in a correct format.
I have a date that is entered into the database in dd/MM/yyyy format via a form.
It is then outputted on another page in a sort of calendar style, ie MMM and dd.
When this form is filled in in the UK, and the date is for example the 3rd April, everything is ok. However if filled out in the US, when outputted the date shows as 4th March.
So my question is how do I ensure, when outputting the date, it's read as dd/MM/yyyy and not MM/dd/yyyy ?
Is it a problem that should be addressed when the data is added, or when it is printed?
For reference:
When the date is added:
value="@DateTime.Now.ToString("dd/MM/yyyy")"
And when it is printed:
<h2>
<span class="month">@row.EntryDate.ToString("MMM")</span>
<span class="day">@row.EntryDate.ToString("dd")</span>
</h2>

I'm bulding document-from-template engine. At certain points I need to match on Reg Exp groups and replace template text with content from a db.
I 'hardcoded' my RegExp initially, doing something like: Regex r = new Regex(@"{DocSectionToggle::(?<ColumnName>w+)::(?<ResponseValue>.+)}[[(?<SectionContent>.+)]]", RegexOptions.Multiline);
it does group capture, so the syntax isn't the prettiest.
Just to make things neater and because I want' to keep the patterns in web.config or elsewhere, I've 'evolved' algorithm to something like:

But I'm getting an error: 'Input string was not in correct format'.
Is this a limitation of string.Format(...)?
In a simple ASPX page, I have an SqlDataSource and a DataList control bound to it.It shows 3 columns; UserName, DateTimeStamp, and Comment.The database table has these defined as nvarchar(24), datetime, and nvarchar(80).The UserName and DateTimeStamp are shown in the ItemTemplate as Labels, while the Comment is a multiline TextBox.I have an event handler for the OnTextChanged for the Comment so that I can update the table as soon as the user tabs off the TextBox.I use the UserName and DateTimeStamp as the Primary Key, and pass all 3 to a stored procedure, where the parameters are declared the same types as the table.What I'm getting though is an "Input string was not in the correct format", which can only be the DateTime that I am passing.
I've tried different date/time formats, but so far come up empty as to the one that will actually work from the C# code.All the different formats I've tried work fine if I pass them to the SP directly via Management Studio, but all throw an error when I use
SqlDataSource.UpdateParameters.Add("DateTimeStamp", System.Data.DbType.DateTime, lblDateTimeStamp.Text);
would the web.config/machine.config connection string look something like this:-
<connectionStrings>
<add name="DB2dbname" connectionString="Data Source=Db2servername;uid=my userId;pwd=myuseridpawd;mode=SHARE;dbalias=DB2TEST " providerName="System.Data.OleDb.OleDbConnection"/>
I have a Date Range in my asp page
<ks:DatePicker ID="txtMinDate" runat="server" Width="65px"></ks:DatePicker>
-<ks:DatePicker ID="txtMaxDate" runat="server" Width="65px"></ks:DatePicker>
Based on the date range selected and input in tthree more textboxes I populate the data grid. The code for the Data Grid is
grvLamination.DataSource = this.Controller.SearchLaminationMain(txtMinDate.Text,txtMaxDate.Text,txtJobNumber.Text,
txtJobName.Text, txtOperator.Text, System.Convert.ToInt32(txtShift.Text));
when i run this code it says Input String not in correct format, if i pass null values for all the parameters , I am using Linq to sql and If i execute the stored proc with null values in the database it works fine, it does not let me pass null values from the C sharp page.
I have a field in my products table called dProductPrice which is a datatype of money. In my datalist i need to display the field as currently it shows price as e,g, 1.3500 but i need it to 2 decimal places so it is 1.35? in my datalist i have done this using the format as well
<%# DataBinder.Eval(Container.DataItem, "dProduct_price", "{0:n2}") %>'
now i have a datatable with a column called cost with datatype decimal.
cartDR["Cost"] = Decimal.Parse(lblProductPrice.Text);
But when i try to populate it i can the input string was not in a correct format. But it works ok if i remove {0:n2}
Is it legal to define a default value for a parameter the way I am in the code below? It keeps throwing an "Input string was not in a correct format." error for me. Is there a different way I should be doing this?
<asp:LinqDataSource ID="lds_numbers" runat="server" ContextTypeName="nrm.prop.myDataContext"
TableName="Sources" Where="myNumber== @myNumber" EnableDelete="True"
EnableInsert="True" EnableUpdate="True">
<WhereParameters>
<asp:Parameter DefaultValue='<%= this.StateItems["myNumber"] %>' Name="myNumber" Type="Int32" />
</WhereParameters>
