So essentially, I have this text editor. How can I make it so when I drop a text file over it, it opens it in textbox2? Or when I doubleclick on the file, it automatically opens it in my program (in textbox2).
View 21 RepliesI believe I need the code for Load Event. I have tried many ideas. I have searched the threads here and also google of course. No luck as of yet. Better description: I have a file named hello.txt. The contents of this text file are "hello". I use my program as the default for .txt files. I dbl click hello.txt. My program loads and the contents are blank and it should have "hello" in it.
View 31 RepliesI'm fairly new to VB.NET, and I'm working on a text editor with a tabbed interface. I deal with large text files. Should I have each tab / text document open up in a new thread or a process? I basically want the entire application to always run fast as the text editor is just one part of it. If I have several large text files open I don't want the rest of the application slowing down a bit.
View 2 RepliesSo I have made a text editor using rich text boxes and it is made to save/open rtf files. I have 3 issues I was hoping to get answers for...
1. Can I (and if so how) make it able to open/save text files and rtf files (so the user can choose which way to save it)?
2. I added the ability to color the words, but instead of coloring just the highlighted parts - it colors everything in the file. How do I change that so it only colors selected text?
3. I also added the dialog for Font changes, but it does not seem to work correctly. I want it to change font/size/etc of whatever is selected. Right now when I highlight stuff and then go into Font it allows the dialog box but does not actually change the font size/type/etc in the file it has open.
Here is the code for the above 4 mentioned areas...
Save...
Try
Dim dlg As SaveFileDialog = New SaveFileDialog
dlg.Title = "Save"
dlg.Filter = "Rich Text Files (*.rtf)|*.rtf"

I had to develope a program that shows a list of names and age in text editor. I am able to open the file in text editor but not getting the names and ages when typing it in the text box and clicking my "write button" or the file menu write. Everything else seems to be working fine with the exception of getting my message box twice from the event load. I don't know if the below is enough for you to assist me but this is what I should see in the text editor:

I am writing a Windows service to import data from CSV files dropped into a directory. One of the steps is to load an XML file with validation rules which I load into a List(Of T). It will pull the data, and then I have it pass the list to a class that monitors the folder and processes the files. After that I clear the list and read in the next file configuration. Now I have noticed that the validation rules aren't matching up and it seems that the list is being passed as a reference type even though the signature is of a value type.Is there anything I can do to get around this?
[Code]...
So here when I pass it, at first it will have 3 validation rules in the new ImportService class I created, but when I call fields.Clear(), it wipes out the class member of the ImportService class.

Application using ado.net
When reading data from an excel file the driver tries to detect the data type of a column based on the contents of that column.
Once it's decided on the datatype then data that is not compatible with that datatype is simply ignored and returned as Null when you read that column using ado.net
For example if most of the column contains numbers then the occasional cell containing non-numeric data is returned as null.
Is there a way to force it to always return all data as text no matter what the actual column contains. ?
a dialogue box to have the user open a file they wish. I'm trying to open a specific file when a listbox item is selected and I have that down but I'm running into the problem of needing to have "" in the display which is impossible from what I can tell in the code. I just need to know what goes in the quotes which will open the file.

View 3 RepliesThere is no editor available for 'file path here'. Make sure the application for file type (.vb) is installed. This is the error that I get when I try to open a project I did a while back in VB. I tried a C# project and I can open the form for viewing fine, but for some reason VB won't work? I really don't want to do a repair on the whole application as it takes a while and I'm not even sure I have the ISO right now.

Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata

Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.
I am new to VB and I have two detail listviews with one full of items that can be droppedinto the other. I have three groups in Listview1 and I would like different forms to open up based on the group each dropped item belongs to. I was able to open Form2 on drop by adding Form2.Show() at the end of the ListView_DragDrop handler sub, but this opens forevery item and I want different forms to open depending on the ListViewGroup the item belongs to.I set the items and groups in the property windows and not in code; I do not know if this makes a difference. So here is the code I have on Form 1 where the listviews are:Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag
[code].....
I insert a text box into form1. I move the mouse pointer on top of the text box. I press down on the left mouse button and begin to drag the text box. The problem is when I let go of the mouse button the text box is not dropped. it remain floating around. My only way out of this is to press the escape key which places the text bnox bak to its original location. Thinking that it might be my mouse I tested it in Power point and everything works correctly.

View 1 RepliesI have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?

I'm currently working on an application that allows users to select picture files and then categorize them into folders. Now I'm having two issues that are probably simple to fix but I only have a year of experience with vb so I just don't know how to fix them. The first and biggest issue is that once the user has selected and categorized a file, I want the program to select the next file in the folder that the first file was moved from. This way the number of clicks required is minimized. However I have no clue what I would need to do in order to accomplish this. Also, my other problem is that I want to be able to find the indexof a quotation mark but whenever I put it in the parameter it just reads it as a quote.

I use text files to hold the program data, which is loaded in to variables when the program starts. I use StreamWriter to write to the text files when they update within the program. This is fine although the writer adds a extra line when I do not want this, which causes the program to error on the next use.

View 2 RepliesI'm adding a method to find and select text in my text editor. Everything worked fine, including the ability to find all instances of the text. My problem came when I tried to make it more user-friendly (doesn't it always?). Originally I had only a menu item with a shortcut( Ctrl + F) which invoked an input box.
Then I added a textbox and a button (similar to that seen in a web browser's Find() method) that calls the method in the same manner as the Find/Replace menu option and displays the desired text in the textbox. Everything works fine except that the text is not selected. I have MessageBoxes displaying the values of required variables in 3 places (marked ***FOR DEBUG ONLY***) to make sure that no values are being changed, but all variables are the same. The method still locates the text, but it is not highlighted.
I think it could have something to do with which object has focus. (When I click the button, the selected text loses focus?). But if I click everything with the menu items, it still works...
