VB.NET App: store a value in vb.net at run time

[karthickbabu]

Is Possible to store a value to declared Variable from Text Box at run time. I want to store a value from Text Box in 2 dimension array. First Value can be sotred in variable(0,0). If i press enter text box will be cleared and get another number and it stored in variable(0,1) and so on

I try like this, but not working any problem in this code

         For i As Integer = 0 To 1
              For j As Integer = 0 To 1
                   FirstMatrixArray(i, j) = Val(txtInput.Text)
                       txtInput.Text = ""
                       txtInput.Focus()
                   End If
               Next
         Next 
 

Let me know your idea about this

Hope your reply

The code you done will update the 2d array every time you trigger the enter.
1. Give i and j declaration as private in that class.
2. Increment i and j value after enter press (in key press event).
3. write assignment statement for FirstMatrixArray(i, j) in key press event after FirstMatrixArray index changed.

I tried all possible ways. But i couldnt get anything. Let me give any example it will help to me.

use variables i and j in the class (class variables)

and use the button click event (users hits enter / clicks the button to submit the value)

set i and j to 0 on the load of the form.

int i = 0, j = 0;
int maxi = 2, maxj = 2;
int[,] matrixArr = new int[maxi,maxj];
 
private void btnSubmitValue_Click(object sender,  EventArgs e)
{
   this.matrixArr[i,j] = this.txtInput.Text;
   j++;
   if(j >= this.maxj)
   {
       j = 0;
       i++;
   }
   if(i >= this.maxi)
   {
       //array has been filled if it reaches this line
       this.txtInput.Enabled = false;
       this.btnSubmit.Enabled = false;
   }
}

I have used an online converter to convert it to vb .net, but havent tested it

Dim i As Integer =  0,j As Integer =  0 
Dim maxi As Integer =  2,maxj As Integer =  2 
Dim matrixArr(,) As Integer =  New Integer(maxi,maxj) {} 
 
Private  Sub btnSubmitValue_Click(ByVal sender As Object, ByVal e As EventArgs)
   Me.matrixArr(i,j) = Me.txtInput.Text
   j = j + 1
   If j >= Me.maxj Then
       j = 0
       i = i + 1
   End If
   If i >= Me.maxi Then
       'array has been filled if it reaches this line
       Me.txtInput.Enabled = False
       Me.btnSubmit.Enabled = False
   End If
End Sub

Hi
Thanks I got some ideas from your code. I will try this code. Surely it will be help to me. I reply after i test this code with my code

Once again thanks
