(Just to give some backstory) I'm making a program to easly create ReadMe's for Fallout 3 mods, and you can check some boxes to show what offical extension you need in order to run that mod. How can I only show parts of a text line? The line will be like: Requirements: (First Extension), (second extension), (third extension).

View 3 RepliesI am creating a simple researcher application to access and store data. As of today it workes by entering a number into a text field and hit enter/button. The result then shows up in a non-menu webbrowser window. What i would like it to do was to exclude the web browser window, and instead show in a popup window inside the application. This should be rather easy, here's what i think might be a problem. I want only to show specific lines from the webpage, not the whole page.

View 5 RepliesI'm writing a program for my algebra students to practice integers.Stuff like....
3-6
-4 + (-5)
3(-4)
-15 � 3
etc.
I want to show an explanation and for the addition and subtraction, I want to show it on a number line. For example, if the problem is 3 - 7, the number line should show and arrow to that goes right to 3, and then left 7 units (starting from 3). Then the student can see that the answer is -4.I could probably do this with some string manipulation, but what would be the easiest way to do it in a picture format? Maybe a bitmap.
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.
I'm fairly new to VB and I had a quick question. I have a multi-line text box that currently looks (line for line) like this:
scn <Name>
Begin <Start Variable>
End
What I am trying to do is make so when I enter text into a different text box (lets call it textbox2) and push an 'Update' button, it replaces a certain part of the original text box. For example:
If I enter "Dogs and Cats" into textbox2 and push update, then this:scn <Name>
becomes this:scn Dogs and Cats
How would you do that? Excuse my lack of VB programming lingo like I said I'm new to this language.
OK, so the following is a link to a picture of my program. I'm including it because I feel it makes things a lot simpler. some information. When you click Rename, it goes to that Rename form. The information already there is the current name. What I plan to do is make it easy to rename the file.What I want is when the user clicks one of the handy buttons, the information appears in the text box (as I've gotten that far already). When the button is clicked again, it removes ONLY the specified information. I don't know if you can, and if you can, what to use. Currently I'm using clear which is obviously wrong. I want essentially:
When button is selected
Append Text Variable A
When button is deselected

View 5 RepliesI am using a label to display a song for an mp3 player. I wanted to scroll the text inside the label for anything that is longer than the label width. I figured out the width of the label and if the width of the text inside the label is longer. But I have no idea how to turn this into subtracting parts/pixels of the text currently displayed and how to append the subtracted parts to the end of the new text.[code]

View 1 Repliesa user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.
now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost
for a "Readnextline" command or something like that?

under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file
