Here’s a brief table of how pointers map to normal (i.e. non-pointer variables) and vice versa (assume you’ve declared the pointer as int *varptr and your regular variable as int v): Dereferencing a pointer: *varptr v Passing the variable by reference: varptr &v Leave a comment if you have further questions and I’ll do my … Read more
I guess you have mis-understood the how does Email Launcher task works. It does not have any login, or log out options. This Email Launchers task will be used to compose a email on configured email on outlook or other POP, IMAP email application. Also you will be not able to test on emulator for … Read more
As you don’t provide any code, answering is a bit of quessing: Is the array you initialized declared globally or locally? If globally try to move it inside the function (if you want the exact same data in it for each time the function is called). If you want to clear the array, depending on … Read more
add 1/3 to itself a large number of times This means that you should add ⅓ a bunch of times: ⅓ + ⅓ + ⅓ + ⅓ + … Then you’re supposed to compare the result of that calculation with the result of multiplying ⅓ by the number of times you added it. So for … Read more
res is the name of a local variable in the function avge that is returned at then end of that function. // Variable of type float with name “res” is declared float res; // Compute some value and assign it to this variable res = (a+b+c)/3.0; // Return the variable to the caller return res; … Read more
string[] x = { “1”, “2”, “0”, “,”, “1”, “2”, “1”, “,”, “1”, “2”, “2” }; int[] y = string.Join(string.Empty, x) .Split(‘,’) .Select(s => int.Parse(s)) .ToArray(); solved How to convert string[] to int in C# [closed]
The problem is you’re expecting integers to behave like strings. The point you’re missing is that: int a = 01; is the same as: int a = 1; There’s no difference. You can’t pad an integer. What you need is to format the integers into a string, using a format specifier. Something like this: pictureBox1.ImageLocation … Read more
You can use functions std::stringstream from sstream or strtod from cstdlib or stod (If you are using C++11) as per your need. Quoting example from cplusplus.com // stod example #include <iostream> // std::cout #include <string> // std::string, std::stod int main () { std::string orbits (“365.24 29.53”); std::string::size_type sz; // alias of size_t double earth = … Read more
There are many ways to do this. Most clean way would be setting ROI (Region of Interest) and then applying matrix operations. Something like: subtract(x(Rect(1,0,NumCols-1,NumRows)),x(Rect(0,0,NumCols-1,NumRows),R) singleLineMask = Mat(1,NumCols,CV_8U) for (int i=1;i<NumCols;i++) singleLineMask.at<int>(1,i)=1; repeat(singleLineMask,NumRows,1,MaskImage) d=mean(R,MaskImage) a=(8*mean(abs(R))-d)/7 assuming you create R and compute NumRows,NumCols prior to this operation and allocate MaskImage. 4 solved conversion of matlab code … Read more
The way you have it written currently, class C would be deriving from A twice (once directly, and once indirectly from B) 5 solved Inheritance misfit
You might want to look into a more complex type of dialog box. Perhaps one with a textbox? This will require launching another form. (see how to display textBox control in MessageBox?) 0 solved By pressing a button i want to show the user all the data inserted to the boxes
Could you not do something like this? Note abstraction of logic to a new method passing in only Inches each time and return a type of double. static void Main(string[] args) { Console.WriteLine(“How many inches would you like to convert?”); int inches = Convert.ToInt32(Console.ReadLine()); double numOfFeet = ConvertToFeet(inches); double numOfYards = ConvertToYards(inches); double numOfMiles = … Read more
You could make use of FormClosed/FormClosing event of the second form. When the second form closes, the event handler in the first form will be invoked and you could call the public method there. Example: public partial class FirstForm : Form { public void OpenSecondForm() { SecondForm form = new SecondForm(); form.FormClosed += SecondForm_FormClosed; form.Show(); … Read more
Please refer to the following MSDN page on passing parameters: http://msdn.microsoft.com/en-us/library/0f66670z(v=vs.71).aspx Personally, I would do data access in a separate class and implement a public void Login(string user, string password, string server) method. The second form would then make use of this class’s other methods to retrieve and display data. 3 solved C# form pass … Read more
This updates the list, and doesn’t create a new list with new contents. for (i = 0; i < list.Count; i++) { list[i] = null; } 1 solved How to make every object in list null [closed]
