I want to add the following What is required when the number is half i.e. 200.5. Whether 200 or 201? By default Math.Round follows MidpointRounding.ToEven enumeration value.

double number = 200.5;
Console.WriteLine (Math.Round(number,0));
Console.WriteLine (Math.Round(number,0, MidpointRounding.AwayFromZero));
double number2 = 201.5;
Console.WriteLine (Math.Round(number2,0));
Console.WriteLine (Math.Round(number2,0, MidpointRounding.AwayFromZero));
//The output from the above code will be
//200
//201
//202
//202

So, if the next higher number is required always, when the value is half way, then MidpointRounding.AwayFromZero is to be used.

If you want low level systems programming or best performance for a large resource incentive application then C++ is good language as the C++ code is compiled directly as native code whereas in managed languages like C# and VB.NET the source code is first compiled to the MSIL and then to the native code by the JIT. But then be warned that the learning curve of C++ is steep and you have to be more cautious as the memory in C++ has to be managed by the programmer. A subtle mistake can lead to a memory leak which may be a nightmare. However, with Managed C++ both the C++ and managed C++ can be taken advantage of. If you want to program for a normal business application, managed programming language like VB.NET or C# is good. In managed programming language, the memory is handled by .NET run time, (Garbage Collector) and hence the programmer can be free from cumbersome memory management. Of course, there may be a little performance hit in managed programming languages when compared to C++, but the difference is not considerable in most of the Business Line Applications. The OOP concept also easy in managed programming languages like VB.NET and C# due to single inheritence rather than multiple inherintance in C++. VB.NET is more like C# except for syntatic difference and has very little resemblence to the VB6. So if you know VB6 it may be of little use. The advantage of C# is that there are so many books available on C# from beginner to advanced level. There are so many on line forums and articles available in C#. Most of the third party libraries are written in C# and the .NET itself is written in C#. If we are stuck in the program, it is somewhat easy to get guidance in C#. Hence, unless there is a specific requirement to use C++, I consider learning C# is easy and advantageous.

Alternatively, if you want to show the user the fomatted text, the MaskedTextBox control with Mask property set as below may be used

MaskTextBox1.Mask = "00 - 00 - 00"
maskedTextBox1.TextMaskFormat = MaskFormat.IncludePromptAndLiterals
string maskedText = maskedTextBox1.Text
'Replace the blank characters
maskedText = maskedText.Replace("_","0")

The mask characters are explained here http://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.mask.aspx[^]

The solution given by Bernhard Hiller works fine. Another option is in the DataSet designer or programmatically, create a relation between Country and Region DataTables like Relation Name: CountryRegion Parent Table: Country, primary key: CountryID Child Table: Region, Foreign key: CountryID

'Now create a BindingSource for Country ComboBox
Dim CountryBindingSource As New BindingSource(DataSet1, "Country")
'Then create a binding source with CountryBindingSource as the parent using the relation
Dim RegionBindingSource As New BindingSource(CountryBindingSource, "CountryRegion")
'Now set the DataSource, DisplayMember and ValueMember properties of both the ComboBoxes
comboBox1.DataSource = CountryBindingSource
comboBox1.DisplayMember = "Country"
comboBox1.ValueMember = "CountryID"
comboBox2.DataSource = RegionBindingSource
comboBox2.DisplayMember = "Region"
comboBox2.ValueMember = "RegionID"

To clear data from each cell of a column of DataGridView, there is no method in DataGridViewColumn class. A method like the following can be used to clear all the cells of a column

Public Sub ClearColumn(column As DataGridViewColumn)
For Each row As DataGridViewRow In column.DataGridView.Rows
row.Cells(column.Index).Value = Nothing
Next
End Sub

The reason is the quantifier + is greedy quantifier, that is it matches everything that matches the pattern up to the end of the input string. In your case it matches password='e X65dere!@#$%^&*()' server = 'localhost' when = is put in the pattern as every thing in between the first ' and last ' matches according to the pattern given when = included. To change this behaviour use the lazy quantifier that is +? instead of + alone.

There were lot of spam posts in the following question How to add a menu item into the Visual Studio 6.0 IDE from an Add-In made in VC++?[^] I have reported as spam. When went to the reputation history and clicked on How to add a menu item into the Visual Studio 6.0 IDE from an Add-In made in VC++?[^] it has opened the answer1 by Richard MacCutchan It seems I have mistakenly clicked on the link to this answer as there were so many spam answers.
