I'm writing a VB.NET app where I want to load an internal text file from Resource. But the code shows Invalid URI: The Uri string is too long. The code is
'document.Load("C:UsersSouDocumentsVisual Studio 2010Projectsinfo.xml")
document.Load(My.Resources.info)
'some processing job with XML node ...
So, how to load the resource file ?
So there's lots of examples of how to do this if your text file happens to be in XML format. However, my text file is not in XML format and as it contains over 172,000 rows I'm not that keen on adapting it (it's a dictionary)! The text file has been included in the project as a resource.
So far I've got a DataGridView (could use a DataRepeater if easier?), a BindingSource and a DataSet.
The DataSet has a DataTable already defined in the designer with one column.I've managed to load the text file into a String and then create a StringReader based on that String variable, however I cannot find anyway of loading those strings into the DataTable.
Dim listWords As String = My.Resources.WordList Dim strReader As New System.IO.StringReader(listWords)
'What now???There are some examples of using OleDb functionality but all assume you're loading from a text file residing somewhere in the filesystem, not a project resource.(I'm also assuming that on building the application the resources get embedded (somewhere) rather than being accessed from [AppDir]/Resources/[filename] ??)
I have a resource fie called ReadMe.txt now i want its text to be loaded on RichTextBox, anyway i can do that?

View 6 RepliesI'm trying to write an application that requires information to be saved once the application has been exited. In order to do this I have been experimenting with storing the data in text files. More specifically I've been looking into adding text files as application resources. I am using VB Express 2008 and added the text file resource through the application tab>>Resources>>Add Resource>>Add new text file. I am able to use my.resources.TextFile1 to read the text file but I am unable to write anything to it. I have tried using my.resources.TextFile1.replace and .insert but neither of those are working out. I was thinking there is maybe a read only setting somewhere, but I have not been able to find any information on this issue.
View 5 RepliesI cannot seem to get my image resources to load into PictureBox1.I can see all the images I added as resources in the solution explorer.They are a series of PNG files with names associated with countries.I am at the beginning stages of randomly changing the image that is displayed in PictureBox1, but I cannot even get the first image to load.Here is my code so far. When I click on Button2 I can see that my array returns a random country, but no image loads.I even tried typing in several of the countries names as well as the country name followed by png (e.g. chine.png) and again no image loads.

I have about 100 PNG images stored in a Resource. Sometimes I need to have the same images in an ImageList, but I do not want to store the images twice in my application, so I add the images from the Resource to the ImageList during runtime when I need them.
Is there an easier way to do this than having 100 lines of code, like the small example below?
imgItems.Images.Add("A", My.Resources.A)
imgItems.Images.Add("B", My.Resources.B)
imgItems.Images.Add("C", My.Resources.C)
imgItems.Images.Add("D", My.Resources.D)

I would like to know how to write to a text file that is added to resources and then have it show the contents in a text box.But I would like to have it on a timer so every second it will refresh as I am trying to make an instant chat program.Also I would like to note that I want it to delete everything after all the users have closed the program. Is there any way to make it so the text file is empty when there is no body using the program any more?

View 8 RepliesI am writing a kiosk type application, in winforms (I know WPF would be better, this is just to be a rough and ready solution until I've learnt WPF), using VB.Net (VS2008).I have a label on my form with the font set to Segoe UI, and at 120pt size (yes it's large, it's designed to be read from a distance on a 42" screen).The problem I have is that the automatic internal padding is pushing my text 60 pixels from the top of the control to the top of the text and 40 pixels from the left of the control to the left of the text - the label1.padding property is all at 0, so this is the default spacing of the control - it seems to be particularly bad with this font (but it's the font I want to use) and if I increase the font size, this issue gets even worse.
I want my text to fit tightly into the boundaries of my control top, bottom and left (I want the right to expand depending on the length of the string in it, though). How can I achieve this (so that I can control all of the paddding myself using the label.padding property) and get rid of this automatic padding?
I'm having a problem with loading two text boxes from a saved text file. I've built a log in form that saves the user-name and password on separate lines in a text file.I have a save button and a load button. My problem is that I'm new to Visual Basics and I can't figure out how to get the two lines from the file to load into their separate boxes on the form.The code that I have loads both lines from the text file into the User Name Box.Oh the username is on the first line in the text file, and the password is on the second line of the text file.

I am trying to create a program which reads data from a text file and insert the data in to a SQL 2005 table, but unfortunately it only reads the first line and insert correctly but not the rest of the lines on the text file

View 11 RepliesI made a text file (.txt) in my project by going to Add New Item and then Text File. I want to have my text file be loaded into the rich text box i have on my form but it doesn't work. It says it can find the file. This is my code:

I am new here and just started visual basic 2008. I want to load a BIG file to edit the text. It is 24MB So whenever I load it in the richtextbox it shows : 7@
:/ Regular text files load fine.
Here is the
CommonDialog1Open.Filter = ("EXE [*.exe*]|*.exe|All Files [*.*]|*.*")
CommonDialog1Open.ShowDialog()
rt1.Text = (My.Computer.FileSystem.ReadAllText(CommonDialog1Open.FileName))
I know I am trying to load .exe! It will load if I save it through the program but will only show 7@.
So i have a text file that is created in the program which can be loaded back into the program(game save)
Whatever is in the text file "stats" should be listed in listbox1 in the same order it is in the text file. The same with "items" in listbox2. And then "quests" will be in listbox3.
The problem is when i load it instead of what is in the text file it says...
note that box3 is correct that it has nothing in it.

Trying to write an app to load a Text file and then search for substrings that contains some specific characters to compose a list. Tried first loading the text file into a StreamReader then search line by line for my substrings. Had to write a lot of code to identify my strings, but it worked ok. Then tried loading the text file into a RichTextBox then use RichTextBox.Find(......) to look for my substrings. The " .Find" property makes the code really simple, but using RichTextBox the app was really slow.
Using Stream the loop was completed in about 2 minutes and using RichTextBox in about 30 minutes! I will need to make a lot of searches and using RichTextBox is lots easier, but is too slow. Is there any way to perform search operations using Streams instead making a loop and go looking line by line??? Or what else would be a good solution to search for strings in a text file??
I wrote the code and it works great but then i thought i'd have a little challenge and go above and beyond. i decided to make a highscore leader board system. i used the following variables and sub classes to make it but im having a slight issue...
CODE:
The idea is that i wanted to make the system able to associate a name with a score, sort the score from greatest to lowest, save it to a text file, load it from the text file, repeat.
so heres a quick list of what i have working...
-Stores name and score
-Sorts by score then outputs
-occasional index of -1 issue
-saves score and name to a text file
-loads score and name when the form loads
-CANNOT add new data to the sorted list...
Thats my main issue. When i have data loaded from last time i try to add a new score to the list but then it gives me an error.
InvalidOperationException was unhandled Failed to compare two array elements
-pointing to the line...
In the details of the exception it continues to say...InnerException {"object must be of type String"}
i don't know which parameter its referring to tho, the variable name is already of type string and count is type integer.
