Validate all the controls of a form in one step in c#

What I was trying to achieve was the following: I created a dialog with some options being entered in textboxes. The textboxes values are validaded using there respective "validated" event. And the user validate the dialog in two possible way: 1 using the "OK" button or, 2 using the "enter" key shortcut.

When implementing the "Enter" key shortcut to validate the entire dialog and close it, the last textbox do not lost focus and therefor do not trigger is validate event, which is annoying.

The solution is to trigger the validate event for all form's children at once before closing the dialog, using the " this.ValidateChildren()" command. Then the "OK" button event is also artificially triggered:

 private void MyControl_KeyDown(object sender, KeyEventArgs e)
        {
            EventArgs eee = new EventArgs();
            switch (e.KeyCode)
            {
                case Keys.Enter: //opens the Options
                    this.ValidateChildren();
                    OkButton_Click(OkButton, eee);
                    break;
            }
        }

 P.S. Do not forgot to set the "KeyPreview" parameter of your form to "true"  :

Word 2007 - Hidden Equation Editor Features

Interesting enough the, to my opinion, most useful feature of Word 2007 concerning the scientific text editing has been hidden or at least not shown in an obvious way to the user.

In fact it is possible when editing with the new equation editor (i.e. using .docx document type) to use keyboard short cut to type the equations. The way the equations should be entered is very similar as latex.

As an example:

• Type ALT + = , to enter the equation editor (you can customize this shortcut)
• Type A + / + B then hit spacebar , and you will get a fraction
• Type A + ^ + B then hit spacebar , and you will get A to the power B
• Type \Omega  then hit spacebar , and you will get the greek uppercase Omega letter
• Type \omega  then hit spacebar , and you will get the greek lowercase omega letter

Here is some unofficial documentation from the Microsoft engineers:

MS Onenote -> Multilanguage proofing

Despite MS Onenote is an excellent tool for taking note on an on going work. There is a very annoying issue when the user desire to take notes in an other language as is computer system language defined by is keyboard! In MS Word you can change the global proofing language for the whole document in a permanent fashion, but in MS Onenote for an obscure reason this option do not exists. The user is supposed to select the text to be proofed in an other language, then go to tab "review", select "language" and finally "proofing tool".

 Of course this is a very fastidious way to proceed.

The proposed approach is to find a way around  the limitation of MS Onenote, using the regional options of the computer. For this purpose we will take an example:
Lets say the computer is set to "French" with a "Swiss French" keyboard, but the user user desires to take notes in English. Simply changing the computer option to English is annoying because the keyboard will then be "American" and the user usually do not want to change is hardware. So the approach is to set the system to get per example "English" and "Swiss French" keyboard:

First get to Control Panel:

 Then go to Clock, And Region

Then click on "Change display languages":

Then click on "Change keyboards..."

Then click the "Add" button:

Then for our example, you need to select "English" and open the "keyboard" menu with the "+" under the "English" tree node as shown on the image below:

 

Once the "keyboard" submenu is open select "show more":

As next Select the desired keyboard, in our example "Swiss French"

To make this configuration, the default configuration of your computer select it under "Default input language":

To switch from one configuration to the other in a quick fashion the user can use the quick access bar shortcuts:

This finalize my first technical notes, if you have comments and/or suggestion please let me know.
