Look into Regular Expressions (System.Text.RegularExpressions) http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconUsingRegularExpressionClasses.asp Regular Expressions allow you to do pattern matching on strings. Here is an example on how to extract URL's...

I did a quick search... I haven't tried this, but here is one that is being offered for free if you exchange web links with the company... http://www.websupergoo.com/abcpdf-1.htm . Of course, if you want to just print to PDF using a PrintDocument, here is a free PDF printer...

Yes, it will return the line number. If you are going to be doing a lot of this type of work, you will definitely want to look into Regular Expressions, which you will find in the System.Text.RegularExpressions namespace. Regular Expressions allow you to find text within text by matching...

Sorry, I did not see you were working with ASP.NET. Disregard what I have said :o . I have very little ASP.NET knowledge

There is no OnClick event. There is a Click event or a CheckedChanged event. If you double-click the checkbox in the designer, it will set up the default event for you ( in this case, CheckedChanged )

If you are going to be doing a lot of work with each file, you may find it better to read the whole thing at once and store it. For example: dim sFullText as String = sr.ReadToEnd() dim linenum as Int32 = FindSequenceLine(sFullText, "32771") 'To use the FindSequenceLine function

Here are a couple functions I put together which might help you out. The FindSequenceLine function may or may not be useful to you. It returns the line number of a specific sequence number. You send the full file text as a string and the sequence number as a string and it will tell you what line...

Assuming Ninel has that option.

dim strDate as String = TextBox1.Text.SubString(0,4) & "/" & TextBox1.Text.SubString(4,2) & "/" & TextBox1.Text.SubString(6,2)

That is not a valid date format. So, you would either have to change the format (e.g. YYYY/MM/DD) or manually validate it or split the string apart and insert the "/" slashes and validate the result.

This is pretty interesting stuff. I enjoy seeing something a little new and different like this. Anyway, I would just pass a reference of the textbox when I open up the keyboard. When you open the keyboard: Private Sub btnOne_Click(byval sender as Object, byval e as EventArgs) Handles...

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged If ComboBox1.SelectedItem = "SomeSelection" Then TextBox1.Enabled = False End If End Sub This works great for me. Make sure you are using...

You can use the ReadLine function to read a single line of text or the Read function to read one character. For example: Dim sr as IO.StreamReader = new IO.StreamReader("C:\filename.txt") Dim strLine as String = sr.ReadLine() 'Read in one line of text and advance the reader one line Dim intChar...

Then, when adding tab pages to your tab control, use: TabControl1.TabPages.Add(new CustomTabPage) or TabControl1.TabPages.Add(new CustomTabPage(5)) 'To specify which row to read Although, you will probably want to keep a reference to the CustomTabPages so that you can access the labels...

You could use something like this. Just set up the labels as needed. Public Class CustomTabPage Inherits System.Windows.Forms.TabPage #Region " Component Designer generated code " Public Sub New(ByVal Container As System.ComponentModel.IContainer) MyClass.New() 'Required for Windows.Forms Class...

You can write your own using the System.Diagnostics.Process class. It has properties like: VirtualMemorySize, PrivateMemorySize, PeakVirtualMemorySize, PeakPagedMemorySize, PagedSystemMemorySize, PagedMemorySize, NonpagedSystemMemorySize which will show you how much memory you are using. Here...

The only thing I would change is I would use txtInfo.Focus() instead of txtInfo.Select(0,0) Otherwise, it looks great.

The best way to show how a print-out will look is to use the PrintPreviewControl. Then, they will see exactly how the printed page will look.

Then, of course, at the end, you have to do this: lblLetterGrade.Text = strGrade 'Show the letter grade in your Grade Label.
