# re: Microsoft recommends using VBisms!?

What I find truely hilarious (perhaps they don't know their own product very well) is

”Use MsgBox instead of MessageBox.Show or Console.WriteLine.“

1) Instead of Console.Writeline ?! does that not depend on what BEHAVIOR you want? :)

2) is this not already made implicit via "Use the Visual Basic Run-Time Library Members" as MsgBox is in the VB namespace?

perhaps they think many of the vb'ers out there won't know this so they have to explicitly state it, I agree with them and it is the problem with VB development; not the tool, the users (note that there are some good vb deverlopers and bad developers in other languages but the number of BAD developers in VB.NET is appalling)

also from a quick reflector it would seem that the vb message box doesn't do a whole lot but it is still further overhead. The majority of the VB namespace is like this.

if (host1 != null)
{
window1 = host1.GetParentWindow();
}
if ((((Buttons & ((MsgBoxStyle) 15)) > MsgBoxStyle.RetryCancel) || ((Buttons & ((MsgBoxStyle) 240)) > MsgBoxStyle.Information)) || ((Buttons & ((MsgBoxStyle) 0xf00)) > MsgBoxStyle.DefaultButton3))
{
Buttons = MsgBoxStyle.OKOnly;
}
try
{
if (Prompt != null)
{
text1 = StringType.FromObject(Prompt);
}
}
catch (Exception)
{
throw new ArgumentException(Utils.GetResourceString("Argument_InvalidValueType2", "Prompt", "String"));
}
try
{
if (Title == null)
{
if (host1 == null)
{
text2 = Assembly.GetCallingAssembly().GetName().Name;
}
else
{
text2 = host1.GetWindowTitle();
}
}
else
{
text2 = StringType.FromObject(Title);
}
}
catch (Exception)
{
throw new ArgumentException(Utils.GetResourceString("Argument_InvalidValueType2", "Title", "String"));
}
(MsgBoxResult) MessageBox.Show(window1, text1, text2, ((MessageBoxButtons) Buttons) & ((MessageBoxButtons) 15), ((MessageBoxIcon) Buttons) & ((MessageBoxIcon) 240), ((MessageBoxDefaultButton) Buttons) & ((MessageBoxDefaultButton) 0xf00), ((MessageBoxOptions) Buttons) & ((MessageBoxOptions) (-4096)));
}



actual MessageBox code


{
if (!Enum.IsDefined(typeof(MessageBoxButtons), buttons))
{
throw new InvalidEnumArgumentException("buttons", (int) buttons, typeof(DialogResult));
}
if (!Enum.IsDefined(typeof(MessageBoxIcon), icon))
{
throw new InvalidEnumArgumentException("icon", (int) icon, typeof(DialogResult));
}
if (!Enum.IsDefined(typeof(MessageBoxDefaultButton), defaultButton))
{
throw new InvalidEnumArgumentException("defaultButton", (int) defaultButton, typeof(DialogResult));
}
if (!SystemInformation.UserInteractive && ((options & (MessageBoxOptions.ServiceNotification | MessageBoxOptions.DefaultDesktopOnly)) == ((MessageBoxOptions) 0)))
{
throw new InvalidOperationException(SR.GetString("CantShowModalOnNonInteractive"));
}
if ((owner != null) && ((options & (MessageBoxOptions.ServiceNotification | MessageBoxOptions.DefaultDesktopOnly)) != ((MessageBoxOptions) 0)))
{
throw new ArgumentException(SR.GetString("CantShowMBServiceWithOwner"), "style");
}
IntSecurity.SafeSubWindows.Demand();
int num1 = (int) (((buttons | ((MessageBoxButtons) ((int) icon))) | ((MessageBoxButtons) ((int) defaultButton))) | ((MessageBoxButtons) ((int) options)));
IntPtr ptr1 = IntPtr.Zero;
if ((options & (MessageBoxOptions.ServiceNotification | MessageBoxOptions.DefaultDesktopOnly)) == ((MessageBoxOptions) 0))
{
if (owner == null)
{
ptr1 = UnsafeNativeMethods.GetActiveWindow();
}
else
{
ptr1 = owner.Handle;
}
}
Application.BeginModalMessageLoop();
DialogResult result1 = MessageBox.Win32ToDialogResult(SafeNativeMethods.MessageBox(new HandleRef(owner, ptr1), text, caption, num1));
Application.EndModalMessageLoop();
return result1;
}

I too was surprised to find these recomendations. Where I work the .net developers do both C# and VB.Net and there is an understanding not to use the VB runtime library if at all possible when writing code in VB.Net. We prefer all developers to use the .net framework methods in both languages. 12/17/2009 2:12 PM | Viktor
