VS 2008 Accept Capital And Lowercase Letters
Sep 9, 2009
Quick question here about how to get it to accept capital and lowercase letters. I am running code that has certain Customer Types such as "T". It returns different information for that customer. There are only 3 types "T", "R", and "C". The rest return the default information. When I enter "t" into the textbox it returns the default information, not the information for "T". How do I go about getting it to accept "T" or "t"?

how do you search a string for capital letters, is there a function I can use to return to me how many capital letters are in a string? I have tried searching this but as yet not stumbled across a function. Most functions I found converted lower case to upper case Etc. I thought InStr might be the one but still looking for information on that one. I did find something along the lines of .char.isupper but the textbox is .text A password 'rating' tool of sorts of which I use a counter so if I enter "STRing" in the textbox for example it will return a 3 add it to the counter and continue with the little algorithm which my rater uses to add up things such as numbers or special characters to get a final score and that indicates to the user how strong the password is.

Anyone know how to use the Len function to return only the capital letters of the string (for instance, APple would return 2)?
If not, is there an alternative way to return the count of the capital letters within a string?

I have a datagridview with 4 columns bound to a datasource. In the first column the user can only type numbers, in the 2nd, 3rd and 4th only letters (done with keypress and editingcontrolshowing).
Now I want that the user's input in the last two columns automatically gets converted to capital letters, regardless whether he is using Shift or has Caps Lock turned on.
[URL]
Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object,
ByVal e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
[Code].....
My only problem is that when I double click a cell in the 3rd or 4th column (those where I want uppercase letters) and then one in the 2nd column, the text in the cell in the 2nd column is showed in uppercase letters too.
Note: It only shows the already present letters in uppercase. If I type extra letters they will get normal font (so lowercase if I don't use shift or caps lock, and uppercase if I do use shift or caps lock). If I don't type any letters and unselect the cell the text changes back to as it was before selecting.
If I double click another cell in the 2nd column (after i clicked one in the 3rd or 4th column and then one in the 2nd column), the present text stays the same, so it don't get showed in uppercase letters.
how it comes that only the first time that I double click a cell in the 2nd column after i clicked one in the 3rd or 4th column the present text gets converted to uppercase letters and, more important

what i want to is convert this string to something like this

I will then confirm the (2) from the client.

I'm keeping track of some things that are numbered and others that are lettered; while NumericUpDown is perfect for selecting numbered things, I need an analogue for selecting lettered things. The obvious choice would be a listbox that just contains all the letters of the alphabet. But I need to show only the appropriate range of letters, so if I want to use a listbox, I need to write a function that populates the listbox with the first n letters of the alphabet; if n > 26, it should continue with aa, ab, and so on. How do I do this?

I am getting instances of SQL server installed on the machine and throwing them into a combobox. This works like a charm but they are showing in lowercase letters. I would like to change this to uppercase instead.I am trying to format the text when I use .Items.Add.
As an example:vb .Items.Add(Format(rs.ServerInstance, .Text.ToUpper))
I do not get any errors, but the items are not changing from lowercase to uppercase. Any suggestions?
