Box - Conversion Error - User Enters 6 Numbers In 6 Different Text Boxes - Displays The Larger Of Those 6 Numbers

Oct 4, 2011

I 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.

Limit The User Input To Exactly 5 Characters?

Mar 11, 2011

I 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

Forms :: Limit The Width Of A Tooltip?

Dec 30, 2009

I am using tooltips to show information that overflows a label. The problem is that when the information is really long it spans the entire width of the screen and is difficult to read, Is there any way to limit the size of the tooltip?I was thinking one way may be to insert linefeeds at points beyond a certain width -- messy, but it would work.

Limit Child Forms To A MdiParent?

Mar 20, 2012

I 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.
