Saving The Value In A Textbox To An Array?
Feb 9, 2010
I have a form that display's 5 text boxes for student names. Each student names has 5 text boxes to the right of it, the text boxes to the right are for 5 test scores to be inputted. I need to save the values of every one of the text boxes to 2 array's that are declared in a Basic Module, (this is my first application that uses multiple forms) but the values need to be saved not when a button is pressed, but when the user changes the text in the boxes.

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"
[Code]....

I have a small class of Object CellValue
Friend Class CellValue
Public CellColor As Color = Color.White
Public CellShape As Shape = Shape.Blank
Public CellName As String = ""
End Class
Then in my main I make an array of CellValue but I want to know if the values are also being passed down with the array.
Dim Plan(SizeW - 1, SizeH - 1) As CellValue
Dim CellW As Integer = PictureBox1.Width \ SizeW
Dim CellH As Integer = PictureBox1.Height \ SizeH
[Code].....
Are CellName, CellShape and CellColor being tied to each element in the array?. The reason is because I need to use these properties to tie certain functions to them. The CellName should have a MachineID which I would have to use to pull some info from a Database.
The Array should also be serialized and deserialized to XML as customer needs to create/edit and delete certain values in the array. And in order to save the array has to be in XML
So the Questions are does it save the CellName, CellShape and CellColor for each element, will it be affected if I serialize and deserialize using XML. If possible, how can I call up the Cellname p.e for a specific array element.

What 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?

I'm working on a project with a large multidimensional array
resrv(200,12,31,33) it keeps track of information on specific dates within a 200 year range.
What I'm looking to do is save the array to a file so that I can load it again when the program is started.
In VB 6 I used to be able to use a simple for next loop into an open file and load it the same way. It doesn't seem to work the same way with Fthe filestream class in VB.net

I made a query for inserting a value from text box to MS ACCESS db
sql = "INSERT INTO Equipment (port_number,display_name,equipment,tonnage,user_privilage) VALUES (" & CLng(txtPort.Text) & ", '" & CStr(txtDisplay.Text) & "', '" & CStr(txtCA.Text) & "', " & CLng(txtTonnage.Text) & ", '" & CStr(cmbUser.Text) & "')"
Actually I meant for inserting the data entered in the text box, but now saving is the code itself i,e; in port_number column 'CIng(txtPort.Text) ' will be saved

I am trying to save the information that I type in some textboxes to a textfile at the the moment I am using the IO.File.AppendAllText to write the information to txt file. When I press the button the information is added to my txt, but when I close my form the information disappears it doesn't save. I have tried using the SaveFileDialog but it doesn't work.
Is there a way that I can save the information that I type in the textboxes to automatically save when I press the button on my form, and make the information save to my txt file when I close my form and the information still be on my txt file when I open the form again The reason that I am using the appendalltext is because I want to add information to the txt file not replace the information that is already on the txt file

i 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,

I wanted to simply on click a button to add those newly created textboxes to an array of textboxes. Starting with those labeled "Address". But I am finding this very difficult. I am able to add those originally on the form into the array very easily. But am unable to add the newly created textboxes into the array.
Here is my code so far below.
Public Class Form1
Dim MyBoxes() As TextBox = {Address, UserName, Password}
Dim Numbox As Integer = 1

I have a scenario in my vb.net project.I have 70 textbox in my form and planing to save it in the database using access.It's hard to explain y is there 70 textbox there but i will just draw it here [code]5 in the column X 14 in row = 70 Textboxes.What i did is I place all the GRAVEL textbox in the table batch with the attribute name GRAVEL by using a string name called GravelLin.[code]I manage to save the text in this manner txtg,txt2g,txt3g,
1. Since the save data in my table in the database is separated by comma, I know how to extract it and place it in there designated textboxes, but im thinking, or my mistake, its a very long code.Is there a way i can make my code not that long??
2. Is there a better way to save my textboxes? in a way that my code will not that long.

My windows form as a bunch of textboxes on it that basically let the user put in different positions/forces that a test cycle then uses. I am trying to let the user save their profile settings/open the settings so they don't have to input the same values every time they want to run the same test. Here is my code so far. basically, when i save my csv file, and open it, all 6 textbox values are plopped in the first textbox instead of being distributed to their original boxes. I just read about a "split" function
code
Private Sub SaveProfileToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveProfileToolStripMenuItem.Click

Okay, that snippet made the file I was trying to open in the %USERNAME%AppDataLocal folder worked perfectly, again, many thanks - But now I'm 3/4 of the way through my program, and I've hit a wall - I have the exact same program I made in VB6, and it works to perfection, but I am TRYING to switch over to .NET, and am finding a lot of difficulties in getting certain things to work - My biggest headache right now [ Which is basically the finishing of my program ] is a bit hard to explain, so this may be a rather long post: One of my programs that I use to keep track of my Music hard drive outputs to an XML file, in which there is one line I would like to be able to 'Replace' through the program I am making now to a different user-defined string, and close [ Applying string change/save ] the XML file. I have my Main Form, a TextBox1 [ I can't get the XML to open in a ListBox like I wanted ], TextBox2, a 'Locate String' Button, a 'Modify' Button, and an Exit Button. I open the XML file with this in my Form1_Load event into my TextBox1:[code]
The <DateValue> is the line I want to be able to modify [ Which the entire string looks like this: <DateValue>2010-04-10T10:00:03.5009756-04:00 </DateValue>, and I want to be able to change the date and time to whatever the user specifies ], which once the XML is loaded into TextBox1, when the 'Modify' Button is clicked, that string is then loaded into TextBox2... This is where I am lost - How can I apply the modified string to the TextBox1.Text [ Entire XML file ], and save it upon program end, without the rest of the XML lines being disturbed? I realized I needed another Button - The 'Modify' Button now loads the selected string into TextBox2, and I have a 3rd Button to 'Apply Modification', which I want to update the <DateValue> string in the TextBox1 [ Full XML file ] from the modified string in TextBox2, then save on exit - Hope this helped clarify things.So here's the routine:
1. Form loads, opening the XML file, and loading it into TextBox1.
2. User clicks 'Modify' Button to load searched string into TextBox2.
3. User modifies TextBox2 entry.
4. User clicks 'Apply Modification' Button, which changes the searched string in TextBox1 to the modified user-defined string.
5. User clicks 'Exit', which saves the XML changes from TextBox1 [ Without messing up the XML file format ], and the program ends.

The EID has a picture from the person also.I decided not to save the image directly into the SQL database, but store it in the application directory.However i cannot seem to figure out how i can save it with a filename taken from one or more textboxes.
This is what i am using right now, but as you can see it saves it as Test.Jpeg
Dim file_name As String = Application.ExecutablePath
file_name = file_name.Substring(0, _
