Once you call Send, there is no mechanism to cancel the message – the class doesn’t raise any events before it sends the email or anything, it just sends it. Just make sure you’re actually ready to send the message before you send it. The … Read more
Not only the commented line, but another will also fail if there is space in the begin of string. First line fail (to compile) because string::find_first_not_of return size_t. And construct string from two size just make no sense. Second line may fail because string::substr accept length (not end) as it’s second parameter. 1 solved c++ … Read more
None! They are both the same code. They are written differently, but take the exact same instructions and comparisons to achieve the result, therefore, they are the same. So, none of them is faster than the other. 2 solved What code is faster? [closed]
Pass the Textbox Text into the function and It will Print all the SqureRoot of the Numbers private void squreRootFinder(string textBox) { string[] numbers = textBox.Split(‘\n’); string data = “”; for (int i = 0; i < numbers.Length; i++) { data += Math.Sqrt(Convert.ToInt32(numbers[i])) + ” “; } MessageBox.Show(data); } 2 solved calculating multi squares in … Read more
From Amy’s link: Introduction of a bot adapter. The adapter is part of the activity processing stack. Refactored state management. A new Dialogs library. Support for ASP.NET Core. The central idea here is that v4 gives you more flexibility as a developer. The new state management system allows you to choose whether the dialog stack … Read more
Group the content in the data-grid using the group description and use group style to make it appear the way you want. solved Is there a way to use headers of multiple registers in a grid?
The first error is because of this: Array myPort;. That’s not how you declare an array, Array is an abstract class that provides methods to operate on arrays. SerialPort.GetPortNames() returns a string array so you can either declare a string array or just remove the Array myPort; declaration and replace the other line with var … Read more
The definition of the namespace is imported when you write: #include <iostream> or #include <stdio.h> by writing using namespace std you don’t import the namespace, you allow using its entities without std prefix, like cout instead of std::cout solved About using namespace std in C++ [closed]
sum = n/100 + (n/10)%10 + n%10; 1) n/100 (n=123) in this statement 123/100 means ans is = 1 2)(n/10)%10 here (123/10) firstly evaluate and ans is = 12, and then 12%10 gets evaluate and ans is = 2 3)n%10 again 123%10 evaluate ans is 3 then statement becomes sum = 1 + 2 + … Read more
Change the condition to i >= 0, There’s a chance that n – 1 >= 0 might lead to an infinite loop. But it doesn’t matter whether it does or not, because in both cases, it’ll not produce the required results. for(int i = n-1; i >= 0; i–){ std::cout << ” “<< arr[i] << … Read more
You won’t get ‘a’ because your second if still runs. The first if changes the value to A or a and the second if adds the KEY value. If you want all z to become a and Z to become A you want to change this to an else if like this: if(message[i] == ‘z’ … Read more
Do you mean you want to add i to values if there is no i in that list? Use FindIndex to check if list contains i it will return the index. If it is not, it will return -1. List<int> values = new List<int>(); private void CheckCondition() { for (int i = 0; i < … Read more
I’m guessing this is what you want to do, but since you haven’t told us your goals we can only guess public void DoWork() { for(int i=2; i < variable/ 2; i++) { if (variable% i == 0) { label4.Text =”yes not”; return; } } label4.Text = “yes”; } I don’t use C# but if … Read more
Use map::find int keyToInsert = 2; std::map<int, int>::iterator it; it = yourMap.find(key); if(it != yourMap.end()){ //alert user key exists } else { //key doesn’t exist } See docs: http://www.cplusplus.com/reference/map/map/find/ 1 solved Counting Occurrences of integers in map c++ [closed]
