Use the CharacterCasing property of the TextBox. textBox1.CharacterCasing = CharacterCasing.Upper; textBox2.CharacterCasing = CharacterCasing.Lower; Contributed from George Shepherd's Windows Forms FAQ See similar questions...

For Domain Names, the computer does not differentiate between upper and lower case characters, so most names appear in all lower case; however, you can register your name in all upper case or a combination of both. Spaces, commas, and periods cannot be used. Underlines can be used instead of spaces but they are often confused with dashes and should be avoided. No. It is up to your company to assign the names shown to the left of your Domain Name. See similar questions...

This usually happens when people double-click on the submit button, instead of single clicking it. If you just click the button once, it should work fine. Also, there is a known problem with older browsers sending your bill submission twice, instead of once. You are seeing the result of the second entry (which fails because your first entry was already processed, but you didn't see the result). See similar questions...

Tags are case insensitive, so it doesn't matter. This is just a matter of style. (You may have noticed that this FAQ is not absolutely consistent in capitalization.) Many people prefer upper case, as it makes the tags "stand out" better amongst the text. Attribute names can also be upper or lower case, as you prefer. But some attribute values are case sensitive. For example, <OL TYPE=A> and <OL type=A> are the same, but <OL TYPE=a> is different from both of them. See similar questions...

A – Yes, the ECF authentication system is case sensitive thereby allowing for mixed case passwords. See similar questions...

No you can use either case, just ensure you are entering using the correct format. IE/ 8 character code See similar questions...

Yes, but due to the fact that the set-up time required for treating all of you teeth is the same as it is to only treat your upper (or lower) teeth, the fee is still the same. See similar questions...

No. There is no distinction between the cases. It does not matter whether you write ?McDonalds? or ?mcdonalds?. Usually the case is chosen for best reading results. Note, however, that on Unix systems, file and authentication case distinction is usually a default, so, index.html and Index.html can be two separate files. See similar questions...

times it is convenient to have the ability to transform select lowercase areas into UPPER CASE characters for emphasis or make up your reasons and justify them later;-) where might this be a handy ability? Say that you were reading email and notices that routinely you would like to receive in CAPS certain Subject matter for your attention. See similar questions...

Readability can be improved by writing Rexx as if it were a human language and not as if it were JCL or assembly code. Avoid having the entire program in upper case, this is known as shouting and does nothing to help readability. It is common to write commands addressed to external environments in upper case, and to use mixed case for Rexx commands and symbols. If a call returns a value that is not a return code, it may be better to call it as a function rather than a procedure. See similar questions...

Some libraries have routines strupr and strlwr or strupper and strlower, but these are not Standard or portable. It's a straightforward exercise to write upper/lower-case functions in terms of the toupper and tolower macros in <ctype.h>; see also question 13.5. (The only tricky part is that the function will either have to modify the string in-place or deal with the problem of returning a new string; see question 7.5a. See similar questions...

You can handle the textbox's KeyPress event and if the char passed in is not acceptable, mark the events argument as showing the character has been handled. Below is a derived TextBox that only accepts digits (and control characters such as backspace... You can do this by deriving the TextBox, overriding the WndProc method and ignoring these mouse down messages. See similar questions...

The ePostman's mail server allows upper case letters but does not distinguish these from the lower case equivalent. Therefore the variations below are valid but will be sent to the same email address It is not advisable to use uppercase letters in the domain name (domainname.co.uk after the @) as various email relay servers on the internet reject upper case in domain names. The ePostman will convert all email names entered to lower case during registration. You can then choose what to use. See similar questions...

In most cases, we recommend caps or a bolder font for the headline. But, try to use umixed case letters for the rest of the sign. If the sign has a great deal of text, type your legend as it would be seen in a book or article. Too many capital letters becomes confusing. Note that we read phrases or groups of letters at a time. You read clumps of letters, together, as one shape. See similar questions...

If you are sure your terminal handles this, the easiest way from versions 3.0.6 and 3.1 of the shell is to set the option PRINT_EIGHT_BIT. In principle, this will work automatically if your computer uses the 'locale' system and your locale variables are set properly, as zsh understands this. However, it is quite complicated, so if it isn't already set up, trying the option is a lot easier. See similar questions...

We only imprint using UPPER CASE letters. Our imprinting is identical to the case and style letters used by the military. See similar questions...
