VS 2010 : Set Initial Value For Textbox As Blank?

ErrorProvider Not Allowing Blank Date TextBox Field
Dec 31, 2009I'm using the ErrorProvider in VB.Net (2005) which is associated with a BindingSource that is bound to a custom object that I have created. This custom object contains a date field that has a "Date" data type that. I am using a "TextBox" to bind the date field in my form. My issue is, whenever the TextBox loses focus and is blank, "String not recognized as a valid DateTime" is displayed by the ErrorProvider and the focus can't be changed to any other control on the Form. It's good that the ErrorProvider validates entries on Date fields by default (I didn't set up my custom object to display this particular error for the date), but it should allow blank values. I want the user to be able to have a blank date with no error message displayed. How can this be done using a Date field bound to a TextBox?

Compare Data In Textbox?
May 6, 2012I'm working on a project that will compare two textboxes and output the difference in a third textbox. To provide some background what I'm trying to do is compare a users active directory groups to another users groups. What I want this program to output is the groups the user already has, groups that need to be added, groups that need to be removed(basically unique values).comparing text will output an integer, or boolean. I need the actual difference outputted in text to have a working document of changes to groups.
Here is an example of what I want it do, but i'm only able to get it working using an excel macro.

Compare Text In A TextBox To Values In A ComboBox ?
May 10, 2009Again a little (for me) tricky thing:Supose you have a ComboBox control with predefined values - to keep it simple, let's add some colors:
- Blue
- Green
- Red
- Yellow
Now you have a TextBox control as well. If you type into the TextBox BLUE (non-key sensitive) I would like to make it recognize that this value already exists. It does not have to do anything else except for notifying me about a match.I do think that the TextBox1.KeyPress or TextBox1.TextChanged event is what I need but I have no idea how to compare to the ComboBox1 items. I've tried to create an Array of my ComboBox1.Items but didn't get much more than errors. Can anybody help? I am sure it is quite simple however, I can't get my mind set to go in the right direction
Compare Textbox Text To Strings In List?
Jun 10, 2009I've build a list of Strings from files. The list itself is working fine (tried it by having ListBoxes and other controls loading its items from there just to make sure that this is not the issue). Now, I am using this list of strings to compare a Text in a TextBox1 while typing to determine if this TextBox1.Text already exists in the list. I am using the following code (where "s" stands for my List items):
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.TextLength < "1" Then
Button6.Enabled = False

Compare What You Type Into A Textbox To A Randomly Generated Password?
May 8, 2012I am setting up a game for my final visual basic program in my computer programming class, and it is supposed to compare what you type into a textbox to a randomly generated password, and then return whether the last character you entered had a higher, lower or the exact same ascii value as the corresponding character in the randomly generated password. Well, in order to test it, I set up labels to compare the two characters... when you type in ALT + 125, the ascii value returns 125, as it should, and it says that the ascii value of the correct character is 142. I typed in ALT + 142, and the character's ascii value, according to what the label puts out, is 196... obviously its converting dec into hex or oct or something... but how do I fix it?I can also tell you that when I typed in 196 to see if it was reversed or something stupid like that, it printed that the ascii value was 49... what's up with that?!
