Tuberculosis (TB) is a disease caused by bacteria that are spread from person to person through the air. TB usually affects the lungs, but it can also affect other parts of the body, such as the brain, the kidneys, or the spine.ultidrug-resistant TB (MDR TB) is caused by an organism that is resistant to at least isoniazid and rifampin, the two most potent TB drugs.
The WithEvents statement and the Handles clause are often the best choice for event handlers because the declarative syntax they use makes event handling easier to code, read and debug. However, be aware of the following limitations on the use of WithEvents variables:
In IE you have to use attachEvent rather than the standard addEventListener. A common practice is to check if the addEventListener method is available and use it, otherwise use attachEvent : You can make a function to do it:You can run an example of the above code here.The third argument of addEventListener is useCapture; if true, it indicates that the user wishes to initiate event capturing.he problem is that IE does not have the standard addEventListener method. IE uses their own attachEvent which does pretty much the same. Good explanation of the differences, and also about the 3rd parameter can be found at quirksmode.
