When I enter a non-numeric value into a numeric field, vb auto validates the field and the system does not allow me to proceed to fill the next text box.
How can I work around this? I want to write code to perform the validation on the numeric.
This is what happened as shown in picture. I cannot continue to input other fields.
field
There is probably an event handler that is limiting the input to numeric fields and possibly setting the focus on the textbox. This could be in Keydown, Leave, TextChanged, or some other events. You can replace this validation code with your own.

I have a combo box in a form which has two options : correct and incorrect. There is another textbox field which is set not required in Required field property of the table but when combo box selection makes "incorrect", it should automatically force user to fill in textbox i.e. mandatory to fill in textbox
Could anyone please help me out how to fix this.
Thanks!
On the After Update event of the combo box check the selected value. If it is "incorrect" set the focus to the textbox and then use the After Update event of the text box to verify the conditions for filling the text box are satisfied otherwise reset the focus back to the text box (and possibly put on a message box to explain why).
I would like to have a line on an Access user-form. Call it Item #1. I would like Item #1 to be a text box where the user can enter any type of information. So for example, say the user entered "Tutoring" and then next to this was an additional Textbox that allowed the user to enter the hours spent tutoring and the date in which the hours were logged.
What I would like is to have a button to allow the user to add a second line (or set of textboxes) when needed, or a third line, etc. Is this something that can be set up on the Access form? Does this need to be coded in VBA? Just looking for some tips to provide me some direction on the best approach.
"If the data should not be stored in a table, it' a bit more complicated. "
You would have to make the text boxes not visible when the form loads, and then make each text box visible on the After Update event of the previous box.
On a normal textbox, I usually use the AfterUpdate event to perform some action. That means the user has to press Enter or Tab after typing, or click in another control, and I have always been happy with that behaviour.
Now I am setting up a Date filter in the header of a continuous form in Access 2010, and I realize that changing the date through the little calendar that comes automatically, does NOT fire the AfterUpdate event, forcing to press Enter after selecting the correct date, which is a bit heavy.
Using OnChange would trigger at every character entered, which is not nice either.
Any suggestion ?
It is a bit late reply but I hope it will help the others.
When using textbox as a DatePicker you should use Change Event with your filter.
However when you are checking your textbox like Form_name.TextboxName it will show last picked date. To avoid that and use currently selected one you need to provide current date like Form_name.TextboxName.Text. Careful here because .Text property is sensitive to focus.
...in short:
Form_name.TextboxName - will show last picked date
Form_name.TextboxName.Text - will show currently picked date
well, after you select a date from the date-picker, the Change event occurs for the TextBox control. Then, call a sub or function or set focus to another control... to avoid event fires for each pressed key, put something like:
if Len(me.activecontrol) < 10 then exit sub
I hope this helps
I use LostFocus event in the textbox. It allows to use the calendar tool and alter the content. The User has to leave the textbox sooner or later, isn't it?
I use it in this way
Private Sub txt_FirstDate_Change()
txt_FirstDate = txt_FirstDate.Text
myfilter
End Sub
I am trying to validate input in this VB program that calculates football stats. If both boxes are empty when a user clicks Update Stats, it should display a message box. However, with this code it shows the message whether both boxes are empty or if they have values entered. Any idea what I am doing wrong?
'validate user input (ensure textBoxes aren't blank)
If passYdTextBox.Text = "" And rushYdTextBox.Text = "" Then
MessageBox.Show("Please enter values into pass yards box or rush yards box")
End If
A better way to check this would be to use the IsNullOrWhiteSpace() method or even doing something like passYdTextBox.Text.Length > 0 as your problem could be due to data types and casting.
I'm sure you have already considered this as well, but this validation alone is not enough to avoid an exception. You will also need to ensure that the Text in the field is numeric before trying to cast the String.
I've reviewed dozens of options/solutions on this and I just can't get it to work.
Simply put, I have a VB.Net Winform that has a textbox where a user can manually type in text or they can use a USB connected barcode scanner (that simulates a keyboard) to capture a UPC.
What I'm trying to do is get the barcode input to get entered into the textbox regardless of which control has the current focus.
I have set the KeyPreview property of the form to True.
I then added some code to the frmMain_Keypress event as follows:
If Me.txtSearch.Focused = False Then
txtSearch.Focus()
End If
Very simple...and it works, sort of...
If txtSearch already has the focus, the entire barcode/UPC gets entered into the text box.
However, if another control has the focus, every character of the barcode/UPC EXCEPT THE FIRST CHARACTER gets entered into the text box. It always strips off the first character.
I placed some debug statements in the above code to see if the initial character was being read at all and it is being read...just not sent to the text box.
I've seen so many other REALLY complicated solutions to barcode scanning and it seems like I'm really close with something really simple, but, obviously it won't work if it strips the leading character.
Hopefully I'm missing something very obvious.
Change the code in your KeyPress event to:
If Me.txtSearch.Focused = False Then
txtSearch.Focus()
txtSearch.Text = e.KeyChar.ToString
txtSearch.SelectionStart = txtSearch.Text.Length
e.Handled = True
End If
That way you capture the first key that comes in.
