Keep Color Syntax In Richtextbox When Finding And Replacing Words?
Aug 21, 2009
when i copy code from vb.net code window, and paste it in my richtextbox, the color synthax is as it displays in my vb.net code window.. this i want to keep when finding and replacing words. i have the following code to find and replace,
Private Sub RichTextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged RichTextBox1.SelectionLength = 0 Dim words As New List(Of String) words.Add("Test")
i want to replace certain words each time they are detected in order to create a correct response. i have managed to replace the word"i" with "you" and "you" with "me" separatley but when both words are detected in the string it dont work....
ElseIf txtEnter.Text.Contains(" i ") Then Dim ii As String ii = Replace(txtEnter.Text, " i ", " you ")
I am using the following code, but cannot get this to work. I have got it to work if the replacement is just of one word. So if the word test is replaced by mouse and the only thing in the file is the word test, it works.
How can I replace like this: CH_IPVOD_filename.mpg > replace the CH_IPVOD_ with nothing for the result of: filename.mpg ?
I would like to replace every instance of ch_ipvod_ with nothing. Public Class Form4 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim fso, inputFile, outputFile Dim str As String [Code] .....
I am working on a program and for one of my features, I need to replace all spaces in a program with - (dashes.) Is there a way in which I can do this?
Example: Start String = "The rain in Spain falls mainly in the plain." End String = "The-rain-in-Spain-falls-mainly-in-the-plain."
I currently have a very long column (5,000+) of which a lot of cells start with a range of zeros which I want to get rid of (the zero's that is). After importing the data from a txt file, I have a loop going through each row in turn getting data from different cells. So I could amend when teh data is being imported or during the loop reading the data.
I've got a string which could or could not contain the substring "/announce". I would like to replace this part of the string with "/scrape" if its found...so far nothing tricky. But heres the thing: I only want to replace it if the '/' in it is the last occurring in the string. Heres what I mean:
Heres a scenario where I want the replace to happen:
MyStringWithRandomText/announce?x=19 would become: MyStringWithRandomText/scrape?x=19
And heres another scenario where the '/' in announce is not the last '/' occuring in the string, so I dont want to replace it:
MyStringWithRandomText/announce/foo?x=19
I hope that made sense. Not sure if there is a way to handle this by only using RegEx
I am having an issue trying to figure this out. I am writing a script editor that uses tabs (a tab control) and I want to implement syntax highlighting. My issue is that every sample I can find on syntax highlighting uses
Private Sub RichTextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged
I have a binary file. If I look at it with a hex editor, the first values are:208, 207, 17, 224, 161, 177, 26, 225, 0, 0, 0, ... etc.It has a length of 330240 bytes I have tried to open it and read it into a string so I can manipulate it and write it back. No matter what I use, I either don't get the correct number of bytes or the values in the string are incorrect. The most common error results in the first values being: 63, 63, 17, 63, 63, 26, 0, 0, 0 .... etc.It is interesting that it appears that any value > 63 becomes 63.
I get the 2nd values by a simple loop:
For lnx = 0 To 99 Debug.Write(Asc(line.Substring(lnx, 1))) Next
I have tried a whole number of ways to read in the file, including filestream, My.Computer.FileSystem.ReadAllText, File.io.readAllLines, etc.All either give me a string length of about 324000 (not sure why) or, if they do, don't have the correct values. Yes, I have tried various encoding options.
I need to find a string (sort of like: "D" & Chr(0) + "L" & Chr(0) + "S" & Chr(0)... ) so I can then replace that portion of the string with a new value, then write out the file.I use the ".indexOf" to find the data in the string.Why can't I load the file into a string? Or, do you know of an easy way to find some text (similar to above) in a file and then replace the next x number of bytes with a new value and close the file?
Basically what I'm trying to achieve is to extract all the words within a piece of string and transfer that from one text box to another text box.
An example piece of the string would be
<laugh:894u8438:4434:words>
However the words within the string will never remain constant and the characters before and after will change. Is there anything that will read the string and take a word from the string without it being pre-programmed. The string it is reading from is uploaded from a text file.
I am writing a little app for the kids at a local kindergarden and I have some trouble with my code. I have a RichTextBox containing several times in the text the name John. I want to replace randomly the name John with other women names like below
So I have this:
Public Sub Replacements() RichTextBox1.Text="John goes to the car and leaves. John it's taking a nap. Since John works late so (s)he won't be home for dinner. John loves the kids and the kids love John and made a really nice picture"
how can i track how many times a specific word appears in a text box then display the number of times found in a message box?
for example if i type this in a textbox: today is really hot, it is not very convinient to be outside, it is better if we go swimming
and i am looking for the word "is" troughout the sentence, it appears 3 times yet I am not sure how to make a code so it does count the times "is" is being found and then display it with a message:
I am trying to update a table in SQl with a description field. The description may contain syntax words and when it does it I get an Incorrect syntax error.
example - if I insert the string "...with a sweet flavor that is..." The "with" messes me up.
I'm experimenting with the RichTextBox control. My goal is to replace certain user input with an image object. For example, when the user used ":-)" in the RichTextBox it will be replaced with a simple image (like ).
I use the TextChanged event on the RichTextBox to replace any found textual smiley with an image. The code below works, but only works on the first found ":-)". When the user used ":-)" twice the first image is being removed from the RichTextBox. No matter howmuch times ":-)" is found, there will only be one image in the RichTextBox (for the last found ":-)").
Private Sub RichTextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged Dim LastIndex As Integer
[Code]....
I also don't know if the whole clipboard thing (clearing it, storing the image, restoring the original data) is the best way to do it, but I will look at that later.
I have a Main form that loads 8 picture boxes. Each picture box is the logo of a different game. What I would like to know. Is there a way to clear the Main form, output text AND load 2 more picture boxes (to indicate whether to go back to the main form or quit the program)? or would I have to make a new form for each game? I can't seem to find the syntax for "CLS" (clear screen).
Ok, Im developing a scripting tool for the program "FPS Creator". The scripting uses of course commands which are split into to groups (Action and Condition)
Anyway to the point :
I need the Actions and Conditions to be coloured so the user knows when the command is correct or incorrect.
I've got an issue with a program I am writing. The specific issue is replacing characters in a parent string by finding, and matching, specific characters within it that are parsed from an external xml file. It's for a chat-like client.Here's the 2 classes I am using to pull the emote strings, titles, and id from external XML:
Imports System.Text.RegularExpressions Imports System.Xml.Serialization Public Class emote
Windows forms .net 4.0 vb application. This is a small trivial thing but I was trying to just change the color of one word in label.text. But its not happening and I have a strong feeling that to make it happen is going to be more extensive than its worth... A snippet of what I am trying to use is below...
Dim _changeLabel1 As String = " Note Fields Marked in " Dim _changeLabel2 As String = " are Required" Dim _attrib As New Label
