View 2 RepliesWhat would be the best way to load and save a multi-dimensional array (of bytes). I've looked through streamreader tutorials but it always seems to instructions on how to save strings. I also know there's a very easy way to save a one-dimensional array, but it doesn't work on multi-dimensional ones. What should I be reading up on?
View 5 RepliesUsing the Microsoft VB 2008 Express program, I'm making a SWd20 character sheet (D&D) to be distributed to a few friends. It's a program where the user can figure out stats, species, class, etc without having to make any calculations him/herself.. but this will all be in vain without saving it..
So I'd love to know how I could make it so the user can save and load the entire file(including buttons, labels, text boxes, menu strips, possibly multiple forms, etc) on his/her own computer.. Is this possible, and if so, how can I go about this?
I've already searched through and found lots on saving text in the files to .txt files, but that doesn't cover everything I need
1) How can I load data from Text file to DatagridView. I want it because I'm making a listener. And when I load a data from text file, i want to edit rows. And this calling the second question.
2) How can I save data, Datagrid to Text file.
I found a code
Dim obj_oledb_da As System.Data.Odbc.OdbcDataAdapter
Public Function ConnectCSV1(ByVal filetable As String) As DataSet
Dim dataSet As New DataSet
[Code] .....
I can load data with this code but I can't save.
My Text File must be like this:

I am pretty good with visual basic and visual studio, but the one problem I have is saving... I am currently creating a game, and it has a lot of variables, I want o be able to save all those variables to a text file and then re-open it later. When it is open, i want the variables to have the original value from the text document.
To sum it up: I need variables to be saved in a text file, and then be able to open the text file back and have the variables have the proper values from the text file.
I have been searching around google, and I found ideas, but I have no idea how to use them. Like using XML or saving a table with " TextFile.WriteFromTable" "TextFile.ReadToTable" but I don't exactly get how to use those (the posts weren't too clear)
I'm building an app to manipulate information in a CSV (tab-delimited) file. The 1st part is to load the file and I'm having a real tough time of it. I'm using MS Visual Basic 2010 Express. Here's the code I have with a few comments:

I am a beginner learning Visual Basic and am creating a simple quiz.I need my program to load the quiz questions and answers from a CSV file that I have created and saved in the resources folder.
I need some code to load the CSV file into VB and then populate a 2D array with the values from the table.
I have a Customer File, and want to serach through the customer file to find a customer. I want to be able to Load the data into an array, and then from that array into the list view. BUT i don't want all of the feilds. I only want 3 (out of a total of 7), CUST ID, FNAME, Lname, etc. When the user clicks on the searched Customer, it then displays that customer in the form.
What I am not sure about doing is loading the file into an array
Edit: The file is a .dat file. I will happily attached my form if someone requires it
EDIT2: Can't count to 7
I'm working on a program that when you click a button called new it pops up a new form asking for you to enter a directory location. If the directory exists it saves it into this file:
"C:WindowsSettingsButtonVariableSaves.ini"
I already have working code that saves each directory entered into the ini file on its own line.
Now in this code I'm trying to call each variable back from the ini file when form1_loads and set it to an array called ary() so later I can set the first 10 saved within the array.
So later:
button1.text = ary(1)
button2.text = ary(2)
and so on to
button10.text = ary(10)
and the reason I set the array to record all lines even if theres more than 10 because I want to be able to add more buttons later on.
Here's my current code for saving lines to an array:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim FILE_NAME As String = "C:WindowsSettingsButtonVariableSaves.ini"

I'm working on a project with a large multidimensional array

View 39 Repliesi need to save an array of intptrs as a part of a structure in a file, vb.net gives me "File I/O of a structure with field 'pList' of type 'IntPtr' is not valid." error, ok i figured and tried to convert them to integers and while it worked for other singular intptrs it did not for the array as it just throws me a conversion error. I then tried rebuilding the array in the new sub of the save structure and while that sorta worked(i think) it then gives a "bad size" error when saving. Im out of ideas, saving the array elements one by one would be suicide as the amount varies and is well in hundreds,

The file structure is fine for retrieving data from the file but when I go to write data to the elements and hit any of the fixed array elements, I get an exception error. this has got to be a sytax problem I am just not seeing.
It seems that I am not addressing the array member correctly yet the same logic pulls it properly from existing records on file.
in a Module I have the structure as follows:
Structure INVOICE
<VBFixedString(6)> Public NUM As String

I'm looking to work on a project at work and I'm preparing to do my home screen of my program and I'm stuck on how to prep for all of this. I want to be able to save projects (and its not just one form that will be saved, 26 future forms to be exact), load projects, create new projects and view available projects to be selected from in the home screen. Really a very standard home screen when concerning professional programming. I'm not quite sure how to go about this or when looking ahead what might be a best practice. I haven't worked with databases, so my knowledge is limited.

I am doing a project for part of my coursework which involves the creation of a series circuit designer.
I am having some trouble with the saving and loading functions; I had intended to save them to a text file with commas separating the component name and the value (if any) attributed with it.
Grid(xcoord, ycoord, 0) contains the component name. Grid(xcoord, ycoord, 1) contains the attached value (resistance or voltage- components such as wires have a value here of 0)
Once the save button is pressed, the text file contains 50 rows of "0".
P.S. Let me know if any other parts of my program are required.
Dim comp(maxsize) as ccircuits[globally declared]
Const maxsize = 50

what I am trying to do is get a program to load data from a text file with multiple lines in the form "Name, Type, Stocklvl, Price, Location, Reorderlvl" then display it all in a data grid. From where it can be viewed and edited as well as saved back into the original file stock.txt as well as generating a separate file reorder.txt which includes data on what needs to be reordered and the date which updates on program exit. I have chosen to use datagridview something I'm unfamiliar with as I figure It'd probably be the most functional to meet my needs of displaying a lot of data clearly as much as 200 items.
