Im trying to do it myself but im not sure how you get letters inputed in a text box to determine which part in the array it is. Here is the problem:
[Code]...
i got the following things:
-A button (called "btnplayvoice")
-A textbox(multi-line enabled, called "txtinput")
-Some *.wav audio files in my "resources" (2 of them called "A.wav" and "B.wav", of course there are still some more sound files in my resources xD)Note: the button and the txtbox are in the same form.
i want to make a program with this feature:When I type "B A"(note between "B" and "A" has a space)into txtinput, then i click the btnplayvoice, it will look up and check the resources and see if the wav file exists there, if yes, it will play the related(same as inputed) sound files one by one in correct order. That mean in this case I should hear "B.wav -> A.wav" in this order.
Im trying to make a search bar that has a Go button now heres where it gets diffcuilt How do i make this search bar take the text in the the text bar and add it into a pre defined weblink and replace a bit of text with that word in the search bar so the user types into the text bar for example they type in NAME HERE so when you click go it taxt for instance [URL] now how could i make it so when you hit the GO button that it takes the text in the textbox and and replaced REPLACE TEXT in the pre defined address and put NAME HERE into the address and then load it up with a web browser and also how would i make it open up with the web browser that the person is useing (since lods of people use diffrent web browsers)
View 3 RepliesI've been developing a arcade game, and as every good arcade game, it has an incorporated scoreboard so that players can see who scored better. My problem is that everytime it enters a new scoreline, it deletes all the previous lines in the text file. The code I've been using is the following:
If player1 > 25 Then
objReader.Close()
MsgBox("O " + jogador1 + " ganhou.")[code]............
I current have an app that I am trying to create. I have 2 List boxes, a textbox, and a command button.What I am trying to do is take about 100 text files that all have certain text in them that I need to change at run time to whatever I put into the textbox. For instance Each Text file has my old company name and I want to be able enter my new name into the textbox and click the command button and the app will open each text file, find the text that I specify and replace it with my new name then save the file into a specified folder.What elements should I be studying to make this happen? So far this is what I've come up with:
OpenFileDialog - to open the file
StreamReader - to read the text files and find the text that I specified
**Not sure on the replace method**
StreamWriter - to write the text from the textbox to the new file
SaveFileDialog - to save the file to the specified location

On the main form of my application, I have a Rich Text Box which is where the user will be entering information. The text is black. then, i have a button which calls the dialogue "Notes" A dialogue appears, with a rich text box. the user should then be able to enter text into the box, click "OK", and the text entered into the Notes dialogue be inserted to the rich text box on the main form -- with the font colour "Red". The rest of the text in the main rich text box on the main form should remain black.

After writing the first line, the text fields are cleared to make space for another round of user input. Simply said, this is how it should look[code]....
I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.
How would I go about replacing a portion of text in a text file with a string?
View 1 RepliesI'm Making a Simple syntax highlighter and I'm Doing the highlighting in the text Changed event of a RTB and for obvious reasons I can't re highlight the whole document each time someone presses a key so i highlight one line each time the text changes. But this creates a Problem. If someone pastes code into the RichTextBox It only highlights the last Line. So is there a way to get if the user typed the text in with his keyboard or pasted it from the clipboard in the text Changed event?

I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString")
Private _myObjectLongName As New ThisObjectLongName("SomeString")

View 2 RepliesI have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.
View 13 RepliesI'm trying to find a way to have text that would be "Live" as in if a user types an incorrect phrase/letter in a text box, a message will appear prior to a "save" button being pressed. It's pretty much the same as when you're registering on these forums, it checks the availabilty of the username as you type it.

How can I make my text box go to the enterd web address, through the user's default web browser?(And not by creating an actual web browser in the application..)
View 5 RepliesI have a User Control that is a ProgressBar with Dock set to Fill. The code is as below. Unfortunately it simply doesn't show the text in the progress bar and why is beyond me skill.
[Code]....
The If Not... conditional code in the set method is there to prevent the SetProgressText procedure running every time the property is set. The Value property of a ProgresBar is an Integer and if the code that is setting it runs through thousands of loops (>600,000 in my case) then there's no point updating the text every time since it can only actually change 100 times for a 0-100 ProgressBar. The 600k looping takes about 2 seconds usually, without that conditional code it takes at least 2 minutes!

how can I insert text into an existing string? I am trying to interpret a solution in an earlier post "How do I insert test into a textbox in the middl of existing text"
solution given was int insertionlocation = 4;string newText = "text to insert";if (textBox1.Text.Length < insertionlocation) textBox1.Text = textBox1.Text.Substring(0, insertionlocation) + newText + textBox1.Text.Substring(insertionlocation); else textBox1.Text = textBox1.Text + newText;
I must determine both how and where I need to implement this solution.What follows is my work in progress. Keep in mind things are added and deleted as I work with it saving a user entry to a file

What is the simplest way to check for an existing file. Every method shown to me in my text and the information gained from the Visual Studio help doesn't seem to work. Each one of them tells me the syntax is wrong. I just want a simple way to check for an existing text file that is in the defualt file location.MSDN told me to use FileSystem.FileExists(file) - VS would not take this and...My text Tony Gaddis (VB 2008) shows:
If File.Exists(FileName) Then
open file...
Else

I have to write data to an existing text file. I know it is possible to write to an existing file. But, my problem is I don't want to append the new data at the beginning or end of the file. I need to append the new data at the specified line.
