I'm making a basic calculator on windows forms c#, everything's running the way I need it to, except that I need to know what I can do to show an "error" message on the textbox for the user everytime they press two buttons in a row, instead of having the program crash and not work. Thanks a lot!
You could have a variable in which you hold the last operator was clicked by user and whenever a button is clicked , you check; if it is operator (like + ,- , & ...) and current variable's value is not equal by new one , you update this variable else you could ignore the button clicked.

Well, I'm creating a system event in which checks whether a user shared a link.
I did an extensive search, but found nothing about how to verify that the user shared this link.
My website is in C#, I did not find how to check for Code Behind.
use sharer.php because it a code and users can change the code in F12 - Inspect Element, so https://www.facebook.com/sharer/sharer.php?u=http%3A%2F%2Fgoogle.com.br try it and enjoy and good luck

I have two variables 'name' and 'amount' for about 100 items.
FYI item is a class and name and amount are its variables.
Now i have to display all my items as a list, with name in the right and amount in left of each row in my windows phone app.
what would be the right way to do it??
Create a new app that uses the "Databound Application" template and you'll get something very close to your needs that should be easy to modify for your exact requirements and provide a useful learning source.

I'm attempting to add a Context Menu option to PowerPoint 2010 that only appears when text is selected. Unfortunately the WindowBeforeRightClick event does not seem to fire if the mouse is inside of a TextBox.
Is there a different event I need to be listening to or a better way to add that context menu?
According to the first answer on this Forum-Thread this is an issue that is known to Microsoft, but has not yet been fixed.
We are experiencing the same issue here.
Our current work-around is to use the WindowSelectionChange-Event. However, this will only work if you want to ensure that a TextBox has to be selected, as the SelectionChange-Event will only fire when you select a new shape.

How can I have the resize handles (the little squares or circles on the corners) during run time in my controls? Is there a component that allow me to have it? Or someone has a piece of code to do it?
