You only add COM exposed libraries or managed libraries as a project reference. For other types of libraries you manually import the functionality of the lib (which it sounds like you need to in this case). Here is how you would call ShellExecute() from shell32.dll in %WINDIR%\system32\shell32.dll without adding a …

I often create business entity objects, such as an Invoice, and then i use [icode]List<Invoice>[/icode] to have a list of invoices... such as the sales for that day. There you are using the generic List<of Type T>.

You should also consider wrapping your SqlCommand, SqlConnection, etc members in a [icode]using()[/icode] clause to ensure IDisposable.Dispose() is called. These data accessors use unmanaged resources so you should ensure that clean up takes place as soon as possible. Please mark this thread as solved since TomW did an excellent job …

Date formatting issues -- which is why you should use parameterized queries so this won't be a problem. Here is an example of SQL Server but you can change the class names over to OleDb: [code=vb.net] SqlCommand command = connection.CreateCommand(); command.CommandText = "SELECT * FROM Customers WHERE CustomerID = @CustomerID"; …

Drop a datagridview on a form and try this: [code] using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace daniweb.dgv { public partial class frmDataGridView5 : Form { private DataTable dt; private DGVColumnHeader colHead; private bool suspendEvents; public frmDataGridView5() { InitializeComponent(); } …

If you're controlling the site but they control the domain, why don't you have them set up a DNS entry for [url]www.domain.com[/url] to your server and host the domain that way? Doing what you're talking about can work but it will be a nightmare to support.

From what I know you can't set drag & drop for a picture box, but you can set it for the form: [url]http://social.msdn.microsoft.com/Forums/en-US/Vsexpressvcs/thread/360629bb-633c-4eeb-92a4-0af75de893fd[/url]

It also depends on how much activity goes on in the database. You need to elaborate on your project a little more.

I tried to update my profile picture and I deleted the old one but now I get an error "Unable to save image" when trying to upload a new picture

Same here. Maybe I will be able to use my iPhone on DW now :)

You shouldn't want to stop base constructors from being called -- ever. This is probably a design issue so please post more code or what your intensions are. If a base class implements a [icode]List<string>[/icode] that and has classes the derive from it -- then it stands to reason they …

Upload the project you have so far and someone will be glad to take a look at it and help implement the functionality required

You can close any number of forms you want at runtime. The only limitation is how you choose to go about it. Explain the call order for these forms. Here is one way to go about it: [code] namespace daniweb { public partial class frmHTTP : Form { private frm1 …

Dim tempBASIC As String = "150000" Dim decResult As Decimal = ((tempBASIC / …

You could stun your professor and take this one step further -- submit the credit card to a merchant for payment processing. They will do extensive validation on the card number :)

That is because you're not returning a value. There are two possible fixes here. [code] public [COLOR="Red"]string [/COLOR]Main(string[] args) [/code] The highlighted section of the code means that it is expecting for you to return a string value. So we can return a string value or change the declaration to …

[QUOTE=adatapost;985608][code] string[] ar = listBox1.SelectedItems.Cast<string>().ToArray<string>(); [/code][/QUOTE] That is handy! For unboxing casts I have always used the .ConvertAll() but this is much easier to call :) What I have been doing: [code] double[] sArray2 = lst.ConvertAll<double>(new Converter<decimal, double>(Convert.ToDouble)).ToArray(); [/code]
