VS 2008 Using The Treeview To Organize Text File?
Dec 25, 2010
I'm thinking of using the treeview to organize my text file. My text file looks like:
0|app1|Z0
1|app2|A1
2|app3|B2
And, the list goes on. I think i should be able to organize this with split command. But I also i have checkboxs on my form. If for example the user unchecked the "app1" then i want only "app1" to be unchecked from the listview, and removed from the text file. The question is how could i remove that specific value from the text file.

Hi, i'm trying to use the treeview to display the text of a rtf (rich text file) file when an specific node if clicked.HomeOMGWOOTFor example, if i pick OMG, i want the text of lol.rtf to be displayed on a richtextbox. But somehow i just can't manage to get it... I know to import the text of a .txt file to a textbox, but using the treeview makes it more complicated.This is the code im using right now:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Select Case e.Node.Index
Case 0
[code]....
Another thing is, that i can't import the *.rtf text into a richtextbox and i don't know why.

I am making an application that will organize the movies and their release dates for me and that it will notify me whenever a movie is released. So far I have the layout almost done with some parts missing.
BASICS
1. At the top as you can see I want the text to display the current day and having the tool tip to say "Today is Tuesday 19, 2009" while I want the text to be centered.
2. I want to have a poster with a specific size (dimensions) that will be displayed when the movie is selected at the data grid and I want the buttons to be able to select the previous or next data grid line, meaning next/previous movie.
3. I want to make the buttons either check all the boxes or uncheck them all. And I want the validate button to be able to compare the date of the selected movie with the current day and tell me If it was released today or not.
4. I will make a menu at the top that will be giving you the ability to add movies or select and delete movies, while when adding being able to specify a poster for the movie.
5. I want every time that I run the app to automatically check the dates and either ask me to remove those who have been released some time ago or give me a message like "Movie was released today".

I have an auto generated class file whit many partial classes (auto generated from an xsd schema). I use VS2010 and VB.NET.[code]I'm developing a part of and business application. The application is used for registration of persons data, invoicing, accounting, and so on. The part I'm developing is a reporting system to the authority via wcf services. In my part I will use VB.NET but the other parts of the system are developed in VB6. We use an SQL server and nearly all the business logic is located at the server side. Because I'm used to use VB6 its difficult to grasp all the OOP things I need to remember to write the code as it should be. In my part of the application I get an xsd schema from the authority and auto generate my schema class file from the xsd file with xsd.exe. I see that it's a much better solution that you suggest, but when I looked at my auto generated class file after reading your answer I see that every partial class has a MyBase = New line in the constructor.I can use this in a way, like you suggest? Sorry for not understanding this earlier! If I understand the behavior of MyBase correct, I can write [code]how should I generate the xml based on the xsd? I want to do this for multiple xsd schemas. Isn't it the a good solution to deserialize the xsd (with xsd.exe) to a class, create object of that class and populate it with data, and then serialize the object back to xml?

A form has 10 textboxes,The form receives data,based on the data received some texboxes are visible or not with the .Visible Property. lets say for example, 5 textboxes are invisible, the other 5 textboxes will be visible and there will be some space between textboxes and it will look weird.for example in this image:I want to organize the remaining textboxes, so it would look like this:
which textboxes are visible or not can vary, it could be the first, second or fifth, or the last four, etc. So, how can i organize the remaining visible textboxes?

I'm working on a program, just to learn a bit more about programming. The program's function (if I manage to do it) will be to accept drag/drop files and create a link to them within the program itself. For example: I drag and drop the .exe to a game I have installed; the program then creates a shortcut within itself; the shortcut is displayed in the program with the name/icon; if I click the icon within the program, game launches.I've already manually coded something to this same effect, but it doesn't automatically add new shortcuts/buttons so I have to keep going back in and reprogramming another button every time I install a new game/program. I'd like to be able to just drag/drop and be ready to go. Any ideas on how I can get this function? I'm using Microsoft Visual Studio 2010.

I have been brought onto a project where a large amount of code has been written. Most of the code is appearing in the MainWindow.xaml.vb file (yes, this is a wpf project but I think the question is appropriate for this forum). The folks who developed the previous versions in Visual Basic 6 told me that they organized their code by using Modules. I was not aware of this practice and I have actually never even used modules. Can I use modules in this way so that I can logically group different areas of functionality within the application? Or is there a more preferred method?

I need some help with how to organize classes in VB.NET. I have a class called parent with methods for adding, deleting etc. But I also need a method that returns a list of all the parents, a list with parent objects. Where do I put this method? Do I put it in the parent class or do I need to make another class called parents?

We have an ASP classic ERP (very large application) that we want to rewrite using ASP.NET. I am looking for a way to organize the application so we are going to be able to separate every program / webpage (over 400) from each other. Every program needs to be independent because many developers will work on the project at the same time.Visual Studio seems to make a DLL for every assembly so I was wondering if it's a good idea to make a huge solution with one project per DLL.[code]This way, we would be able to deploy every program separately without altering the others. We would also have over a thousand DLL to manage...

I'm trying to create a program that will manage and organize my music (mp3) files. So I used a ListView (SongList) to show the files that are in my music directory. Then I'm using a class found online to get the Title, Artist, and Album. Then it will insert it into the ListView and assign it a tag with the same value. But then when you hit the button to start the organizing the real problems start.
What it is suppose to do is check if the chosen directory exists then if it does it will create a folder for the artist of the song it is processing then a folder for the album then copy and rename (title) the song into that folder, then move onto the next song. But when it tries to create the directory it says there are invalid characters but there aren't. Also for some reason it wont put the Album name into the string for the directory???
Heres the function used to do just about everything:
Code:
Function CopySong(ByVal SongPath As String, ByVal SongName As String, ByVal SongArtist As String, ByVal SongAlbum As String)
If System.IO.File.Exists(SongPath) = True Then
Dim RootDir As String = "C:UsersCalebDesktopMusic"

how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)

I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.

I have a project with 150 (i counted) Items in the "MainProject Components" area of the toolbox panel.These 150 classes are mostly database related objects like table adapters, and datasets that i hardly ever use. I also have about 10 custom classes that i use often.When i need to access the toolbox, I have two issues that i would like to resolve.
1.How do i organize the toolbox to separate my custom controls from the table adapters and datasets?
a.I have created a custom tab within the toolbox.
b.I have dragged and dropped my controls into this new area.
c.All is well until I exit my program and re-open it. Voila they're all back in the MainProject Components" tab.
2.How do I force the IDE to instantiate the toolbox panel as completely collapsed?

how to do this for vb6 however i am using vb 2008 and the code for vb6 does not seem to work.
I have designed a form with a text box on it, and a command button underneath. The idea is to run this as a sort of stiky notes section.
I want the text box to read rich text into the textbox (C:\\stickynotes.rtf")
Then i have a command button underneath which i want to save the content of the rich text box to the rtf file (C:\\stickynotes.rtf). This is so that the user can edit and ammend information.
here is some code i have so far
Dim fileReader As System.IO.StreamReader
fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\\stickynotes.rtf")

I have a treeview on my ASP.Net page and for some reason the text on some nodes gets cut off, I am programatically adding all the nodes and am aware of the existing issue listed here: [URL] however I am not changing the font and as you see in the code below this fix does not work for me.
Private Sub populateTreeView()
'Code that gets the data is here
Dim ParentIds As List(Of Integer) = New List(Of Integer)
[Code]....
The strange thing is that this issue only appears in IE, I have tested it in chrome and Firefox and both browsers display the text perfectly.
When I select a node this fixes the problem and all text displays as normal.

just ran into an odd problum with treeview node text I add a top node and I wanted it's text in bold. The bold works fine but half the text is missing
Here an example
vbnet
Dim sFont As New Font("Verdana", 8, FontStyle.Bold)
Tv1.Nodes.Add("TOP", "0123456789", 0, 0)
The code above for me only shows 012345678 and not showing the 9 any ideas if I use regular style it works fine only happens when I apply the bold style.
