The short answer is to send the UITextViewController the “resignFirstResponder” message … the trick however is when to send the message. In my case, and I assume it would be the same for others, is to listen for any changes to the text in the UITextView and if the carridge return character ‘\n’ is detected then send the “resignFirstResponder” message to the UITextView.

Step 1. The first step is to make sure that you declare support for the UITextViewDelegate protocol. This is done in your header file, as example here is the header called EditorController.h:

1
2
3
4
5
6
7

@interface EditorController : UIViewController  {
  UITextView *messageTextView;
}

@property (nonatomic, retain) UITextView *messageTextView;

@end

Step 2. Next you will need to register the controller as the UITextView’s delegate. Continuing from the example above, here is how I have initialize the UITextView with EditorController as the delegate …

1
2
3
4
5
6
7
8
9
10
11

- (id) init {
    if (self = [super init]) {
        // define the area and location for the UITextView
        CGRect tfFrame = CGRectMake(10, 10, 300, 100);
        messageTextView = [[UITextView alloc] initWithFrame:tfFrame];
        // make sure that it is editable
        messageTextView.editable = YES;

        // add the controller as the delegate
        messageTextView.delegate = self;
    }

Step 3. And now the final piece of the puzzle is to take action in response to the “shouldCahngeTextInRange” message as follows:

1
2
3
4
5
6
7
8
9
10
11
12
13
14

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range
  replacementText:(NSString *)text
{
    // Any new character added is passed in as the "text" parameter
    if ([text isEqualToString:@"\n"]) {
        // Be sure to test for equality using the "isEqualToString" message
        [textView resignFirstResponder];

        // Return FALSE so that the final '\n' character doesn't get added
        return FALSE;
    }
    // For any other character return TRUE so that the text gets added to the view
    return TRUE;
}

• Declare a string variable and release it from memory manually

 NSString *str1 = [[NSString alloc] initWithString:@”Hello World …”];

 NSLog(@”%@”,str1);

 [str1 release];

• Declare a string variable and automatically release it from memory

 NSString *str1 = [NSString stringWithString:@"Hello World ..."];

 NSLog(@”%@”,str1);

 OR

 NSString *str1 = @”Hello World …”;

 NSLog(@”%@”,str1);

• Append string variable with new string

 NSString *str1 = @”Hello World …”;

 str1 =  [str1 stringByAppendingString:@", Goodbye world"];

 NSLog(@”%@”,str1);

• Grab a substring of a given string from start till character index

 NSString *str1=@”Hollo World”;

 str1=[str1 substringToIndex:3];

 NSLog(@”%@”, str1);

 Output:

 2012-05-03 20:16:42.245 Project_7[74969:903] Hol

• Grab a substring of a given string from character index till end of string

 NSString *str1=@”Hollo World”;

 str1=[str1 substringFromIndex:3];

 NSLog(@”%@”, str1);

 Output:

 2012-05-03 20:16:42.245 Project_7[74969:903] lo World

• Use Dynamic array with memory allocation

 NSMutableArray *DynArray = [[NSMutableArray alloc] initWithObjects:@”Hello World”, nil];

 [DynArray addObject:@"Goodbye World"];

 NSLog(@”%@”,DynArray);

 [DynArray release];

 Output:

 2012-05-03 19:57:21.555 Project_7[74850:903] (

    “Hello World”,

    “Goodby World”

 )

• Change array index order

 NSMutableArray *DynArray = [[NSMutableArray alloc] initWithObjects:@”Hello   World”,@”Goodbye World”, nil];

 [DynArray exchangeObjectAtIndex:0 withObjectAtIndex:1];

 NSLog(@”%@”,DynArray);

 [DynArray release];

 Output:

 2012-05-03 20:01:58.293 Project_7[74896:903] (

    “Goodby World”,

    “Hello World”

  )

• Remove object index from array

 NSMutableArray *DynArray = [[NSMutableArray alloc] initWithObjects:@”Hello World”,@”Goodbye World”, nil];

 [DynArray removeObject:@"Goodby World"];

 NSLog(@”%@”,DynArray);

 [DynArray release];

 Output:

 2012-05-03 20:05:52.639 Project_7[74933:903] (

    “Hello World”

 )

• Use NSDictionary for store one table name

 NSDictionary *DicObj = [NSDictionary dictionaryWithObjectsAndKeys:

                            @"Mohammed", @"FirstName",

                            @"Al-Atari", @"LastName",

                            @"23", @"Age", nil];

 NSLog(@”%@” , DicObj);

 NSLog(@”%@”, [DicObj objectForKey:@"FirstName"]);

 Output:

 2012-05-03 20:36:41.401 Project_7[75304:903] {

    Age = 23;

    FirstName = Mohammed;

    LastName = “Al-Atari”;

 }

 2012-05-03 20:37:40.666 Project_7[75332:903] Mohammed

•  Use NSMutableDictionary for store one table name with initializing the object

 NSMutableDictionary *DicObj = [NSMutableDictionary dictionaryWithObjectsAndKeys:

                            @"Mohammed", @"FirstName",

                            @"Al-Atari", @"LastName",

                            @"23", @"Age", nil];

 NSLog(@”%@” , DicObj);

 NSLog(@”%@”, [DicObj objectForKey:@"FirstName"]);

 Output:

 2012-05-03 20:36:41.401 Project_7[75304:903] {

    Age = 23;

    FirstName = Mohammed;

    LastName = “Al-Atari”;

 }

• Convert string to integer 

int value =  [textbox1.text intvalue];

• Convert integer or decimal to string to show in text field

CtrlLbl_Equal.text =  [NSString stringWithFormat:@"%d", 1234];

•  Use NSMutableDictionary for store one table name without initializing the object

 NSMutableDictionary *DicObj = [NSMutableDictionary dictionary];

 [DicObj setObject:@"Mohammed" forKey:@"FirstName"];

 [DicObj setObject:@"Al-Atari" forKey:@"LastName"];

 NSLog(@”%@” , DicObj);

 Output:

 2012-05-03 20:36:41.401 Project_7[75304:903] {

    Age = 23;

    FirstName = Mohammed;

    LastName = “Al-Atari”;

 }

• Generate a random number 

int intrnd;

intend = arc4random%10 // will generate a random # from 0 – 9

• Use UiAlertView for showing a message box

UIAlertView *Alert =  [[UIAlertView alloc]

initWithTitle:@”Colors”

message:@”Please choose a color”

delegate:nil

cancelButtonTitle:@”Cancel”

otherButtonTitles:@”Red”, @”Blue”, @”Green”, nil];

[Alert show];

[Alert release];

• Use UiAlertView for showing a message box and get the selected value

implement UIAlertViewDelegate on ViewController interface

@interface ViewController : UIViewController<UIAlertViewDelegate>

- (IBAction)BtnChooseColor:(id)sender {

    UIAlertView *Alert =  [[UIAlertView alloc]

                           initWithTitle:@”Colors”

                           message:@”Please choose a color”

                           delegate:self

                           cancelButtonTitle:@”Cancel”

                           otherButtonTitles:@”Red”, @”Blue”, @”Green”, nil];

    [Alert show];

    [Alert release];

}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

    //NSLog(@”%i”, buttonIndex);

    switch (buttonIndex) {

        case 1:

            self.view.backgroundColor =  [UIColor redColor];

            break;

        case 2:

            self.view.backgroundColor =  [UIColor blueColor];

            break;

        case 3:

            self.view.backgroundColor =  [UIColor greenColor];

            break;

        default:

            break;

    }

}

• Use UIActionSheet for showing a message box

 UIActionSheet *sheet =  [[UIActionSheet alloc]

                             initWithTitle:@”Colors”

                             delegate:self

                             cancelButtonTitle:@”Cancel”

                             destructiveButtonTitle:@”Delete”

                             otherButtonTitles:@”Red”, @”Blue”, @”Green”, nil];

CX: present digit number

Today, I had to build web form that took user input from standard ASP.NET input controls. In one of the text boxes the user must to enter a valid URL, so I had to make some validation logic. But first of all, I had to find out what kind of URL’s we would accept as being valid. These are the rules we decided upon:

•     The protocol must be http or https
•     Sub domains are allowed
•     Query strings are allowed

Based on those rules, I wrote this regular expression:

(http|https)://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?

It is used in a RegularExpressionValidator control on the web form and on a business object in C#.

<asp:RegularExpressionValidatorrunat=”Server”

  ControlToValidate=”txtUrl”

  ValidationExpression=”(http|https)://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?”

  ErrorMessage=”Please enter a valid URL”

  Display=”Dynamic”/>

Here is the server-side validator method used by the business object:

using System.Text.RegularExpressions;

privatebool IsUrlValid(string url)

{

  returnRegex.IsMatch(url, @”(http|https)://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?”);

}

You can add more protocols to the expression easily. Just add them to the beginning of the regular expression:

(http|https|ftp|gopher)://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?

You can also allow every thinkable protocol containing at least 3 characters by doing this:

([a-zA-Z]{3,})://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?

 These commands should work in Internet Explorer 7 on XP or on Windows Vista.

Most often, these DNN performance issues are due to the website application code having to load into memory. Typically, an ASP.net application stays running in memory until a certain period of inactive time has elapsed. At this point, the operating system removes the application code from memory until the next time a website application request occurs. In a shared hosting environment, this allows for more efficient usage of memory resources for the websites which are active.

However, the downside for your inactive website is usually a big performance hit the first time your website application loads into memory again. A typical solution used by many website owners to overcome this performance problem is to use a “Keep Alive” service, which forces your application code to stay in memory.

“Keep Alive” services accomplish this by “pinging” your website at configured intervals. This simply keeps the website application from reaching the set “inactivity setting” where it is removed from memory.

While Microsoft does have a Application Warm-Up feature in progress for the IIS 7.5 environment, not everyone has their IIS environment upgraded to the 7.5 version. Also, those sites running on shared hosting environments may not even have this option available for them to use.

There are websites available which will provide this service for you, some free, many for a fee. The reality though is that it is very simple to create your own “Keep Alive” service.

All this requires is a copy of the Visual Basic Express development environment, which you can download for free from Microsoft’s website. Once downloaded and installed, simply create a new console application, which will create a new module file by default.

Simply replace the default code Visual Studio added to this new module with the code below. You can add lines in the Main procedure to check as many sites as needed.

Compile the application and then copy the application executable file from the project bin folder to a place on your hard drive. You can use Windows scheduler to run the application every 5, 10 or 15 minutes. It will then ping your website for you automatically.

As an added benefit, the application will send you an email if it does not receive a valid response code from the ping operation. Using these emails gives you a simple site monitor, so that you can know if your site goes down for any reason and approximately when based on the time of the email.
