how to write only capital letters into textbox and also into combo box.
suppose if user writes 'abc' in above defined control then vb should to display
it in 'ABC' into textbox or in combo box.
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?
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 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

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"?
