Text Check - Color And Word Order

Jan 12, 2011

I recently started wondering about how Microsoft would go about checking the text and checking its color, word order (spell check), etc. and I was trying to think of how they would do it if they were forced to write something, like Word or the text editor in Visual Studio, in Visual Basic.NET. Ways that I thought of could be using an array, setting a string to a word in that array, and check if that word is in the text. However, after I tried it, I realized I had to set the .SelectionStart property to zero, which got annoying if the document was long. Also, with arrays, though I could store the strings in a text file and read from that, I was limited to the number of items I could have, and I'm sure it would get frustrating if I added or subtracted a word (then having to back in the code and replace all of the instances of that array.)

Then I started thinking about streams. Though I have not tried them yet, I would imagine that if they had to be used, the problem of speed would come up again. But what if the stream only checked say 30 characters before and after the current selection start? Well, that would solve the speed problem, but it would bring up another. Every time the caret position changed, (if we were checking for color changing) we would be limited to those 60 characters. Say the word is "hello". What if "hello" began 31 characters behind the current SelectionStart? "h" would remain the same color, but "ello" would turn the default color (this is because we would have to reset the color everytime just in case the user changed a certain word.)

Change Color Of One Word When Appending Text To RichTextBox

Apr 15, 2011

I'm trying to find a way to change the color of one word when appending text to a Rich text box. So if I append the sentence "This is a sentence with a specific word in one color" The entire thing will be in black except for the word "specific" it will be in red or any color I choose. The same thing will happen if the next line appended is "Please be specific in your request". All back except for the word "specific". I don't want the text added then someone has to click a button to change the color. It should happen as it's appended.

Checking For Vowels In Each Word And Order Them

Nov 13, 2011

The text file words.txt contains a list of words. Write a program that displays the words in a list box sorted by the number of different vowels, they should be ordered first by their length(descending) and then alphabetically. The display should show both the word and the number of different vowels in the word.

So I have
Private Sub btnDisplay_click handles(...) btnDisplay.click
Dim Words() as string= io.file.readalllines("words.txt)
I can use for each word in words to check each word but I don't know how to check how many vowels are in each word or how to order them.

Switching Order Of Words In VBA Word?

Jan 4, 2012

I need my VBA Macro to locate text throughout a document and move it. The information that needs moved can easily be detected by the font colors. For example:

"Celica Toyota": Toyota would always be a specific Green font and Celica would always be a specific blue. There can be more than one word in the range that needs swapped (ie: "Monte Carlo Chevrolet").

I have some really long drawn out code, but there's got to be something more efficiant.

Permission Conflict - Close Word Or Visual Studio In Order To Save The File

Jan 8, 2010

I write an HTML file with MS Word, and use it on my application. The problem is that I need to close Word or Visual Studio in order to save the file, or compile the code, because each one reserves the file permission rights. The html file is only written by word, and only read from VS. At compile time, the file is copied to execution directory. Is there a way to give both programs simultaneous permission rights?

VS 2008 Add The Word To A Text File And Create A Folder With The Word As Its Name?

Apr 25, 2009

The following code allows words to be added to a listbox. Add the word to a text file and create a folder with the word as its name. The second part undoes the actions.If I try to delete the word immediately after adding it one of two things happen.

1.An error is reported stating the path cannot be found. Although the listbox index value is correct according to the code the error is pointing at that index +1.

2.The code continues to the point of requesting conformation to delete the folder, still pointing at the index value +1. I the action is confirmed the wrong folder is deleted.

However if I stop debugging, then run the code again all works correctly.Is it likely to persist when the application is compiled?

Imports System.IO
Public Class Form1
Dim pathlist As String = "M:Visual Studio 2008ProjectsEnvironment and Conservation GlossaryEnvironment and Conservation GlossaryGlossary List.txt"

2010- Sorting A Set Of Labels Against The Previous Set In Order To Check The Answer And Accuracy?

Apr 23, 2012

I have a program which is made with 12 labels, the first set of six are randomly generated and the second set are values obtained from the first set and the user has to choose in ascending order the numbers on the first set.The values chosen will be trasferred to the second set and then with a "check" button that set of labels have to be rearranged and compared to the user input.If the user for example manage to choose the right order, he will obtained a 6 of 6 and he will recieve a message.My problem is on the rearrage and compare part.

The code I made is very simple but is not working, basically it only check if the next value is smaller that the previous and changed its back color according to the case.

Here the code:

'check button
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim Score As Integer
Score = 1

[code]....

I would like to have a correct rearrange of the numbers and introduce a message according to the accuracy of the user.

VS 2010 Make A Program In Which If The Textbox Text And The Listbox Text Are The Same Order?

Apr 25, 2012

im trying to make a program in which if the textbox text and the listbox text are the same order, which they are in the picture, a bluie fonted text saying well done appears. However only the red text appears which is only meant to come when the order of the text in both listbox and textbox isnt the same.

Here is the code that i used for this:

listarrays = name of listbox
textbox1 = name of textbox

l is the name of the label for correct answer(blue font)label3 is name of label with red font which should only appear for wrong answer

Dim text As String = Me.TextBox1.Text
For Each item As Object In listarrays.Items
If item.ToString = Me.TextBox1.Text Then

[code].....

use another textbox instead of the listbox but thats just making itmuch harder for me as I already made the full code working with the listbox. My lecturer told me i need to convert both in string so both textbox and listbox are compatible and i did so (see code above) but the correct label doesn't show?

Sep 29, 2011

I'm curious to know if there's a good way to see if an object is a System.Drawing.Color before I try casting it to one. Right now it seems the only way I can do that is to put it in a Try/Catch block and if it hit's the catch part then I know the object isn't a color.[code]I really don't like this because there's a slight flicker while it fires up the Exception handling and I would really rather use an If Else End If for this than a Try/Catch.

Check For Hyperlinks In MS Word?

Jul 31, 2010

I want to add an if statement that checks if there are no hyperlinks in the document and if there are no hyperlinks display a message that there are no hyperlinks in this document.The problem is that Word is divided in stories, so the body of the document is a separate story from the footnotes story of the same document.So when I attempt to check for hyperlinks the if statement checks the body of the document first and if there are no hyperlinks in the body, then exits the program even though there may be hyperlinks in the footnotes story.
