Calling a string through a function using an array and UITableView as indicator


Calling a string through a function using an array and UITableView as indicator

I wish this help you You need to create a valid NSIndexPath.
Like this for example : NSIndexPath(forRow: 0, inSection: 0)
code :
func callString(var yzx: String, tableView: UITableView!, forIndexPath indexPath: NSIndexPath!) -> String {
    var task = arrayOfTasks[indexPath.row]
    var yzx = task.name
    return yzx
}

let label = UILabel()
label.text = callString(String(), UITableView(), forIndexPath: NSIndexPath(forRow: 0, inSection: 0))

fixed the issue. Will look into that further You could wrap the call itself in an object that handles displaying the loading message, maybe retrying a few times on errors or whatever. Something like this:
code :
public abstract class AsyncCall<T> implements AsyncCallback<T> {

    /** Call the service method using cb as the callback. */
    protected abstract void callService(AsyncCallback<T> cb);

    public void go(int retryCount) {
        showLoadingMessage();
        execute(retryCount);
    }

    private void execute(final int retriesLeft) {
        callService(new AsyncCallback<T>() {
            public void onFailure(Throwable t) {
                GWT.log(t.toString(), t);
                if (retriesLeft <= 0) {
                    hideLoadingMessage();
                    AsyncCall.this.onFailure(t);
                } else {
                    execute(retriesLeft - 1);
                }
            }
            public void onSuccess(T result) {
                hideLoadingMessage();
                AsyncCall.this.onSuccess(result);
            }
        });
    }

    public void onFailure(Throwable t) {
        // standard error handling
    }
    ...
}
new AsyncCall<DTO>() {
    protected void callService(AsyncCallback<DTO> cb) {
        DemoService.App.get().someService("bla", cb);
    }
    public void onSuccess(DTO result) {
        // do something with result
    }
}.go(3); // 3 retries

wish of those help In this function parameter list, argv is a pointer to a C string array (char **).
Using the Objective-C NSString or NSArray type isn't possible with this function, First, convert each string using -(const char *)cStringUsingEncoding:(NSStringEncoding)encoding;, and store them into a C array of strings.
code :
// myString is "arg1"
// mySecondString is "arg2"
char *cString = [myString
                 cStringUsingEncoding:NSUTF8StringEncoding];
char *cSecondString = [mySecondString
                       cStringUsingEncoding:NSUTF8StringEncoding];
char *myStrings[2] = { cString, cSecondString };
int returnCode = cFunction(2, myStrings);

To fix this issue I want to run a loop that will call a user-defined function which has the exact same name as the element in an array. I have defined 4 different functions by the names "India", "UK", "USA", and "Japan". , Consider:
code :
Sub dural()
    For i = 0 To 3
        Select Case i
        Case 0
            Call India
        Case 1
            Call UK
        Case 2
            Call USA
        Case 3
            Call JAPAN
        End Select
    Next i
End Sub
Sub luxation()
    Countries = Array("India", "UK", "USA", "JAPAN")
    For i = 0 To 3
        Application.Run (Countries(i))
    Next i
End Sub
Sub India()
    MsgBox "India"
End Sub
Sub UK()
    MsgBox "UK"
End Sub
Sub USA()
    MsgBox "USA"
End Sub
Sub JAPAN()
    MsgBox "Japan"
End Sub

I wish this helpful for you Here is my example for better understanding of my question. lets say: , You can use the [] syntax together with the spread operator ....
code :
var a = ["Hello", "World"];
var b = "Hi";

console.log(b["concat"](...a));
