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 use for example:
Dim S As String = TextBox1.Text
if(S.Contains("BlaBla") Then
' ..
End If
But when I use blabla in my textbox it doesn't work..How Can I ignore the capital letter or non-capital letter function?
I want to know on how to convert small letter to capital letters. I want to convert every letter automatically once I press the keyboard. Im going to wait for your replies.
View 7 RepliesI 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.

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

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.
View 2 RepliesQuick 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"?

way to return letters like a,b,c,d,.......,x,y,z,aa,ab,ac,ad,.......az,ba,bb,bc,bd,.......bz, in visual basic. I am adding them to the headers of a datagridview. Sort of like excel numbers the headers on columns.
View 2 RepliesI'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?

Question regarding fluent nHibernate table mappings:Apparently I was under the mistaken impression, that with an ORM tool, such as nHibernate, one could gain database independence - at least in table creation.Now, I have an automated toowhich creates fluent nHibernate mappings for me.It also works fine (though only if ALL tables have a primary key...)

I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.
I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string
