Hi! I have been posted content of ccna1 final exam (latest and only question.) I will post the answer and insert image on sunday. If you care, please subscribe your email an become a first person have full test content. Subcribe now Some question have not content because this question have images content. So that can you wait for me? SUNDAY 1. A user sees the command prompt: Router(config-if)# . What task can be performed at this mode? Reload the device. Perform basic tests. Configure individual interfaces. Configure individual terminal lines. 2. Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C. During this attempt, a frame was captured with the source MAC address 0050.7320.D632 and the destination MAC address 0030.8517.44C4. The packet inside the captured frame has an IP source address 192.168.7.5, and the destination IP address is 192.168.219.24. At which point in the network was this packet captured? leaving host A leaving ATL leaving...
You can use Character.isLetter(char) on TextBox's KeyUpHandler:
ReplyDeletetextBox.addKeyUpHandler(new KeyUpHandler() {
public void onKeyUp(KeyUpEvent event) {
if (!Character.isLetter(event.getNativeKeyCode())) {
((TextBox)event.getSource()).cancelKey();
customPopup.showRelativeTo(textBox);// your styled PopupPanel
}
}
});
But, Character.isLetter(char) works with ASCII, if you want more see you can do it something like that:
/**
* A better implementation of isLetter -- the default GWT version doesn't support non-English characters.
*
* @param c the character to check
* @return whether the character represents and alphabetic symbol.
*/
public static boolean isLetter(char c) {
int val = (int) c;
return inRange(val, 65, 90) || inRange(val, 97, 122) || inRange(val, 192, 687) || inRange(val, 900, 1159) ||
inRange(val, 1162, 1315) || inRange(val, 1329, 1366) || inRange(val, 1377, 1415) || inRange(val, 1425, 1610);
}
/**
* Checks if an int value is in a range.
* @param value value to check
* @param min min value
* @param max max value
* @return whether value is in the range, inclusively.
*/
public static boolean inRange(int value, int min, int max) {
return (value <= max) & (value >= min);
}

You can write some validation code on keyTyped event to check, what was the last letter typed. Was it a number or not. If not then show error message.
ReplyDeleteTry considering KeyLister method : keyTyped()
You may add regex to do this
ReplyDeleteJavascript to allow Alphabetical characters
ReplyDeletefunction AllowAlphabet(e)
{
keyEntry = !isIE ? e.which : event.keyCode;
if (((keyEntry >= '65') && (keyEntry <= '90')) || ((keyEntry >= '97') && (keyEntry <=
'122')) || (keyEntry == '46') || (keyEntry == '32') || keyEntry == '45')
return true;
}
