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.

I've created a rich text box which stored the "textBox.Text" value in an SDF database. The storing works, but the formatting seems to be lost. Is this something that SDF databases can't handle? Do I need to store in binary or something? Not sure how to do that either.I'm using Visual Basic Express Edition with Winforms and writing in VisualBasic.NET btw This is how I store to the database:
Private Sub btnToolStripSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnToolStripSave.Click
Try
Me.Validate()
Me.SangerBindingSource.EndEdit()
[code]....
And this is how I insert the text in to the rich textbox
txtBoxText.SelectionFont = New Font("Verdana", 16, FontStyle.Bold)
txtBoxText.SelectionColor = System.Drawing.Color.RoyalBlue
[code]....

I have two RichTextBoxes, each of which can have any sort of formatting. I need to be able to take the rich text from box 2, complete with formatting, and add it to the end of box 1, preserving the formatting of both box 1 and the appended rich text.
I've not managed to find anything usefull on this anywhere apart from hints pointing to manually re-building the RTF codes for the result (but no actual VB / C# / C code to perform this or similar).

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?

When it comes to storing SQL in code, most people use strings:Dim strSql As String = "Select Foo, Bar From FooBarTable Where Something = @Something"The problem is, when you have very long SQL strings, reading them in code becomes difficult. You can usually split the strings up like this:
Dim strSql As String = "Select Foo, Bar From FooBarTable " & _
"Where Something = @Something"
This causes a number of problems:

2 forms, on the first form I have a listbox which recieves it's items from a datagridview, when I click on a button all the items (in the listbox) are converted to a string and add to a richtextbox on the second form.
On the second form I have also a numericupdown, and here is what I run into.
With the numericupdown I want to multiply or remove blocks of strings from the richtextbox.
For example, when clicked on the button (form1) a string is add to the richtextbox, when I click (on form2) on the upbutton of the numericupdown I want to add the same string again below the existing one with 2 blank lines between them (this can be down a lot of times). When I click the downbutton, a string should be removed.
In short term, the amount in the numericupdown should be the amount of string blocks in the richtextbox.
Here is the code I use to copy listbox.items to string and add them to the richtextbox:
Public Sub SGLists()
Dim i As String
For Each i In Me.ListBox1.Items

I have the following code, which generates insert queries
For Each f As String In Directory.GetFiles(d)
objSQLStringBuilder.Append("insert into table1 (full_path, file_name) values ('" & f.Replace("'", "''") & "', '" & f.Remove(0, Len(d) + 1).Replace("'", "''") & "');")
Next
However, the paths which it finds are formatted as follows
c:program filesmicrosoft officewinword.exe
I need to format the paths as follows
file:///c:/program%20files/microosoft%20office/winword.exe
How can I modify the above code to do this?

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:
Format(Now, "MMMM d, yyyy at H:mm ampm")
I can get everything except the Timestamp in VB.NET.
Code:
Format(Now, "MMM, yyyy 'at' H:mm AMPM")
produces - December 10, 2008 at 13:13A12P12
I need 1:13 PM, not 13:13.I can't find anything to format the time to AM/PM vs. military time.I've tried String.Format with no luck either.

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")

I am trying to format a date from a table that I'm getting so that I can concatenate it with another string.But I want the leading zero - I don't want 1/1/2009 - I want 01/01/2009.

I'm having some difficulty formatting some of my strings, I can't see what's wrong unfortunately. I have various numbers, e.g. 100.023, 13488.323, etc in a datagridview column that I would like to be formatted so it looks like this: $123,456
Here's what I've tried so far (that isn't working):
row.Cells(1).Value = Format(row.Cells(1).Value, "{0:D0}") 'I've also tried using {0:C0}
row.Cells(1).Value = row.Cells(1).Value.ToString("$#,#")
'This one (above) comes up with an error saying it can't put an "##" in an Integer column, something like that anyway.

Im trying to format the length of a DataGridViewComboBoxColumn based on the length of the longest string in the comboBox. Here is the code I currently have but it only formats the DataGridViewComboBoxColumn based on the users previous selection in the comboBox.
Is there a way to have the DataGridViewComboBoxColumn at the length of the longest string in the comboBox? Here is my code.

I need to take a string of any length & make it exactly 5 characters long by either truncating it or padding it or neither. So "abcdefgh" becomes "abcde", "abcde" stays "abcde" & "abc" becomes "abc " (2 spaces at the end).
I currently use this line of
Microsoft.VisualBasic.Left(myString, 5).PadRight(5, " "c)
it works, but it seems very hackish.

I have:
1 ComboBox(cboCultureInfoNumeric) with the required CultureInfo.
1 Textbox(txtNumeric)
1 Label(Label1)
When the user change the Culture info the decimal point or comma change in the textbox(txtNumeric) nicely.What i try is to change also the text in Label1 by the culture info.If the user change the CultureInfo to German the Label1.text = �German�If the user change the CultureInfo to Spanish the Label1.text = �Spanish� And so on�
What I have do is :
1 - Set the Form1 Localizable property to true.
2 - Set the form's Language property to "German (Germany)".
3 - Set the Label1 Text property to "German".
VB make the file -> MainForm.de-DE.resx with name: Label.Text and value: German
4 - Set the form's Language property to "Spanish (Spain)".
5 - Set the Label1 Text property to " Spanish ".
VB make the file -> resx
6 - Set the form's Language property to "French (France)".
7 - Set the Label1 Text property to "French".
VB make the file -> resx
8 - �The TextBox with the numeric value�s change when the user change the CulureInfo but not the Label1, why?It work perfect when I put �Thread.CurrentThread.CurrentUICulture = New CultureInfo("fr-FR")in the MainForm.designer.vb before InitializeComponent function and in the New function.But I want to use the ComboBox�

I've been working with an Infragistics Ultragrid and I'm looking for a helpful hint. I'm using a table from SQL Server 2008 to populate my grid. The table that I'm calling has a column that has been updated to be something like this. "Items" + char(9) + char(9) + "Cost" + char(13) + char(10). The "Items" section of the column is padded to be 50 charcters in length followed with the two tab characters, the cost then the new line characters. Ultimately this is what the results of a single row would look like. Notice how the items and the cost are lumped into a single cell.

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?

In my app I present to the user an option to customize the name of the file that gets produced. The format string the program reads is something like "yyyyMMdd-%1-%2-%3-%4" which the user can customize to his liking. In this case the format of the date is yyyyMMdd and the %1 is the trip number like 1000P, %2 is the origin code like PTTTT, %3 is the destination code like PHYUD, and %4 is a secondary stop code like YYYY123. I'm having problems taking the actual data and formatting into the custom string. I believe its the date format that I'm getting stuck on.
So far I have
sOut = txtFormatPattern.Text
sOut = sOut.Replace("%1", "1000P")
sOut = sOut.Replace("%2", "PTTTT")
sOut = sOut.Replace("%3", "PHYUD")
sOut = sOut.Replace("%4", "YYYY123")
sOut = myDate.ToString(sOut) 'date is July 01, 2007
The output is "20070701-#1000P-PTTTTP12YUD (YYYY123)"
The problem obviously here is my last conversion. The string contains key characters that denote a part of the date specifically in PHYUD. So my question is how can I give my user the flexibility to format the output as they wish and then convert that properly?
