Apply Formatting String When Binding DateTime To MaskedTextBox?

Feb 24, 2010

I have a MaskedTextBox using the mask "00/00/2�00" to restrict input to a format of XX/XX/20XX, with the Text property bound to MyBindingSource.SomeProperty of type DateTime.

Recently, values with a single-digit month or day recently started displaying incorrectly. I expect that the ToString() method is being called on the value at some point in data binding, and I believe the call is not padding month / day with zeroes.

I tried setting the format type of the MaskedTextBox.Text property to DateTime in the advanced data binding properties, but it didn't help.

How can I apply ToString("MMddyyyy") when converting the DateTime object to a string, before the value is bound to the Text property?

Apply CODE Formatting To A TextBox?

May 28, 2010

I'm playing with a simple string replacement editor for editing VB.Net functions outside of VB. Is there a way to apply VB.Net code formatting to a string?

For example. The txtboxCodeEntry looks like this:

If strVar="dummy" then 1 else 0 Endif

I would like it to "autoformat" to:

If strVar = "dummy" Then
1
Else
0
End If

The formatting would match whatever formatting VB.Net does when you're editing code in the Visual Studio IDE.

Apply Colour Formatting To A Richtextbox *as User Types*?

Oct 18, 2010

I have a RichTextBox with an OnChanged event. The OnChanged event should look at each line in the RichTextBox and if the line is of prime length colour it red, otherwise colour it black. How do I do this? I think it is possible to select from index a to index b and set selection colour, but I think this will lose my cursor position.

Converting C++ Printf Formatting To / From String Formatting

Sep 30, 2010

I have some VB .NET software that interfaces to a load of old (but sound) COM objects. The VB provides a GUI for the COM objects, part of which consists of setting various options on the COM objects - several of which relate to string formatting.I have a simple pair of VB .NET functions that convert basic %f, %d, %g formats to/from .NET equivalents using a large select case covering specific common strings, but they don't cover all formats.[code]Before I start diving in and making it more versatile with some parsing, does anyone know of a class (eg VB or C# .NET) that provides a decent ready-made implementation? Or perhaps some regexp wizadry could be used?

Regex.IsMatch - Apply On Byte Or String Level?

Jul 21, 2010

I would like to know if the result of RegEx.IsMatch is affected by encoding. I am checking if a string is contained within another one by using a regular expression pattern. I am 99.9 % sure the pattern is correct, so my question is... The matching test with the Regex.IsMatch, is applied on "byte level" or "string level"?

This one is the Output... TEΣT
This one is the Word to match... ΤΕΣΤ
And here is the pattern...
If Regex.IsMatch(Output, "(?<=^||s)" & Regex.Escape(Word) & "(?=s||$)") Then

I'm having trouble getting a data stamp to format correctly in VB.NET I need a date stamp exactly like this:

December 10, 2008 at 1:27 PM In VB6, this works perfectly.

Code:

produces - December 10, 2008 at 13:13A12P12

Formatting - How To Convert Decimal To String

Apr 14, 2009

I have an app that deals with currency. For display purposes I use the nifty VB FormatCurrency function which will format based on the OS's region setting. So, if in France you might get 123,45 where in the US you would get 123.45. To perform calculation on these amounts I use CDec() to convert to decimal.

My problem is that when I convert the Decimal to a String using toString() it formats according to the currently set region. I need to be able to always convert the decimal into a String representation for the US, i.e. with decimal points. I thought I would be able to do something similar to this:
.toString("#0.00")

Preserve Formatting From NumericUpDown To String?

May 15, 2012

My form contains several NumericUpDown controls. These controls show different amount of decimal places. Later in my code I put the different NumericUpDown.Value's in a string array arrStr() like so:

arrStr(1) = NumericUpDown1.Value
arrStr(2) = NumericUpDown2.Value
arrStr(3) = NumericUpDown3.Value

Then I print the array with the File.WriteAllLines function to a text file.
If for example NumericUpDown1.Value = 1.00, NumericUpDown2.Value = 2.30 and NumericUpDown3.Value = 2.124 the file has the following values in it:

1
2.3
2.124

[Code].....

I have tried Format which works, but that formatting method is not convenient as the amount of decimal places is already set for each NumericUpDown. It would be annoying to do the work again, but now with Format.

DateTime Conversion From String?

Jun 18, 2012

I am getting this datetime format in an xml file:

2012-06-14T11:15:41.587-07:00
2012-06-14T10:49:32.397-07:00
2012-06-11T11:10:49.2-07:00

I believe I understand some of it, please correct me if I am wrong:

2012-06-14 = date

T = time identifier

10:49:32.397 = hour min second milliseconds

-07:00 = I have no idea

I need to convert this to something I can sort on for my datagrid view.

When I try something like this:

Console.WriteLine(String.Format("{0:d/M/yyyy HH:mm:ss}", "2012-06-14T10:49:32.397-07:00"))

I'm getting the original string back out with no conversion.
