In your form design, make the base layer a TabControl and then create tabs for each “page”. Ensure that your button is not on a tab page, but on the base form. Then, handle the button click, switching tabs to a new “page” each time. Keep track of the current page using a member variable … Read more
Edit – if the question is: “How to create console application in Visual Studio?” – @emd provided good link: How to: Create a C# Console Application Answer to: “How to create utility that takes CS file and run it as an executable?” If you projects are all in single file (or group of CS files) … Read more
You’ll need a place to hold your current value, in the example I’ve made it to be a local named pageNum. Inside your loop then, you’ll increment that variable and assign it to the Page property on the PlayerSearchParameters object being constructed in its initializer. If you want the method to wait for the async … Read more
You declare a class template PointIndices, but misspell it in the function definition: template<typename T> PointIndicess<T>& PointIndices<T>::operator=(const PointIndicess<T>& point) // ^ extra “s” here ^ and here solved Template overloaded = operator works in one class and fails to compile in another? [closed]
var itemCounts = list.GroupBy(l => l) .Select(g => new { key = g.Key, count = g.Count()}); 3 solved I want count uniques along with value in array? [duplicate]
Your + operator is not designed correctly. In every case, you omit the second argument to the constructor of Integer (whose name is positive), so every integer you make there will have positive set to true, and hence (a1+a2) is always positive (i.e. positive is true). 0 solved When I run the code down below … Read more
The snippet below will work, using standard LINQ: var nearestBelow = newValue – array.Where(n => n <= newValue) .Min(n => newValue – n); solved C# Nearest Low Value in array [closed]
Here’s a simple way to make the pattern you want from the data you have. I’m going to use an array rather than reading from a file, but it shouldn’t be hard to do that if you want to. Basically, the trick is to look at the index of each item at each position in … Read more
it is not compiling. I am calling a function which is called by reference but there is an error which is can not convert double * to double solved it is not compiling. I am calling a function which is called by reference but there is an error which is can not convert double * … Read more
Just for fun and surprisingly fast: public static int GetSignature(string value) { int result = 0; for (int i = 1; i < 12; i++) // 12 should be more than enough for Int32 { if (value[i] == ‘>’) { break; } result = (result * 10) + (value[i] – ‘0’); } return result; } … Read more
The three statements after for are the initialization, the test condition for continuing the loop, and the statement repeated on each loop. We want to initialize delayTime to 50,000. We want to continue if delayTime is greater than or equal to 100. And we want to multiply it by 0.9 each loop (preferably without doing … Read more
You should store the result of IndexOf() and use that. var result = Array.IndexOf(myarray, myvalue); if ( result > -1 ) Console.WriteLine(“the value existe in myarray[” + result + “]”); solved Is there a way to get the index value when using …. Array.IndexOf? [closed]
Is something like what I expected standardized in C++17 No. , or proposed for standardization later? There is no such proposal in any of the mailings. Though of course there’s plenty of easy workarounds, so there’s little reason for such a proposal: oy ? std::max(x,*oy) : x; x < oy ? *oy : x *std::max(oint(x), … Read more
I would change the following type of test: if (txtFirstName.Text == “”) To: if (string.IsNullOrWhiteSpace(txtFirstName.Text)) // .NET 4.0+ if (string.IsNullOrEmpty(txtFirstName.Text)) // .NET before 4.0 And for your additional test (no spaces allowed in the string): if (string.IsNullOrWhiteSpace(txtFirstName.Text) && !txtFirstName.Text.Contains(” “)) // .NET 4.0+ if (string.IsNullOrEmpty(txtFirstName.Text) && !txtFirstName.Text.Contains(” “)) // .NET before 4.0 Note: You will … Read more
