Forms :: UpDownNumeric Value To RegKey?
Jun 7, 2010I am trying to write a control interface for a backup script I am using. I got everything to work so far except for the UpDownNumeric controls I use to select values for timeouts and port numbers for the backup and emailer functions.All of the information gathered from the form is written to registry keys in HKLMSolignis For whatever reason and this is my problem, when I set the value for the UpDownNumeric the first time they work just like they should and create a regkey called SMTPPortNumber when I click the "Generate Config" Button.But if I modify the value of the UpDownNumeric and click "Generate Config" again they do not change in the registry.If I change any of the values that are not UpDownNumeric objects they update just fine when I click the button a second time.I am storing the value of SMTPPortNumber as an Integer = STMPPortNumber.Value?

Database "update" Button To Validate The Input Before Applying It To The Dataset ?
Jan 22, 2009Ok, so I have created an Access database, and everything is working fine (much to my amazement) except for one thing. I want the database "update" button to validate the input before applying it to the dataset, and if there is an error (empty field) I want it to pop a message and highlight the text box in question where the error occured (there are 7 textboxes).
How precisely do I go about doing that?
CODE:
This is what I have so far for the update button. I attempted the "textbox1.isnullorempty"
VS 2008 Validate A Groupbox To Make Sure Radiobutton Is Checked - VB 2008
May 12, 2010Is there a way to validate a groupbox with a couple radiobuttons in it to make sure that one of the radiobuttons is selected?
Heres why I need this. I need a user to be able to select their class rank out by way of radiobuttons in a groupbox. When they click submit, I need to validate that atleast one of the radiobuttons got selected and if not display a messagebox.
I got one reply early of:
If myGroupBox.Controls.OfType(Of RadioButton).Count(Function(rb) rb.Checked) = 0 Then
'There is no RadioButton checked in myGroupBox.
End If
Is there any other ways other then that? Preferrably a more 'dumbed' down way? This is for just an entry level VB class, I would prefer not to use something of that nature if there is another way.

VS 2008 Validate Whether Or Not Information Exists In A Datagrid?
Dec 8, 2009What is the best way to validate whether or not information exists in a datagrid. Let me give a situation.
What I'm trying to do here is allow the user to search and sort the dgv based off of the character or string that is he/she inputs into a textbox. The things I want to validate are:
The textbox is not blank, and if not blank has valid information. (easy enough)
The dgv has actually been populated from the dataset!!!!!
The second I can't seem to nail down, regardless of what I use. I have tried using rowcollections, columns.count(), cell, item, and a few other properties all of which either get skipped over by my if statements or throw an index is out of range error.

VS 2008 - Using RegEx String To Validate Email Address?
Feb 11, 2010I am using this regex string in one of my programs to validate email adresses: "^[a-z0-9._%+-]+@[a-z0-9.-]+.[a-z]{2,4}$". This works well for the most part, but I just found out that it doesn't catch an address like this ... "john.doe.@yahoo.com" ... where there's a "." right before the "@", which is invalid, so my program tries to send it & throws an exception. How to modify my regex string to catch this situation?

May 9, 2009is there any function to validate if a string has only numerical characters? I can cross character for character and verify if it is a number. But I look for something simpler or if already a function like that exists.

I need only numeric characters (no comma nor points

When saving to the db, some records will have this column filled in, some won't. I want to use linq to update this column on each record that is null to a value of now() but am not sure what event to use. Is there an event like BeforeCommit or something like that? Or is my way of doing this completely inefficient and there's a much better way of doing this?

VS 2008 SQL Insert Or Update?
Dec 17, 2010I've got results in a loop format from a XML file, I want to either insert them into my SQL database or update them if they are already there. My question is more around lodgic, do I have to
1. Get each item.
2. Do a search for it and see if it's in there.
3. If not add
4. If so update
Or is there a quicker way because with 200 records at a time, search then update/insert will slow down the process.
