Box - Conversion Error - User Enters 6 Numbers In 6 Different Text Boxes - Displays The Larger Of Those 6 Numbers
Oct 4, 2011I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

View 1 RepliesLimit The User Input To Exactly 5 Characters?
Mar 11, 2011I have 200 dynamic textboxes.
I am trying to limit the user input to exactly 5 characters ( not more, not less ), and numeric only.
I have been trying this :
Private Function txtValid()
Dim str As String
For Each txt As TextBox In Panel1.Controls
[Code]....
But it always shows the last messagebox. Not all 200 textboxes will be filled in, so I suspect that it may have something to do with that, but I just need to stop the user from entering alphabetical characters, and the entered field must have a length of 5

View 4 RepliesLimit Child Forms To A MdiParent?
Mar 20, 2012I have this function
Private Sub createChildForm(ByVal winForm As Form)
'Take a form and set app as its parent form
winForm.MdiParent = Me
winForm.Show()
End Sub
When some one wants to view the "About" form, it's called like this:
createChildForm(New f_about)
But my function doesn't stop them from creating an unlimited number of about windows and I need to put that limit to one form.
For example, I will have a login screen, but I don't want them logging in over and over again in different accounts because my subroutine doesn't stop a form from being created/opened more than once.
