You can do something close in javascript – this function is possibly not the prettiest way to do it, but it’s generic the first argument is the “root” object, this is followed at least 1 “nodes”, and the last argument is the value function assoc(root) { var parts = arguments.slice(1); var value = parts.pop(); parts.reduce(function(result, … Read more
In the given HTML code, you have given selected=”selected” for the “No” option. You need to give that in “Yes” option as follows. <div class=”col-sm-6 col-xs-12 col-md-6 col-lg-6″> <label for=”headoffice” class=”col-sm-6 col-xs-7 col-md-4 col-lg-4 control-label”>Head Office Member<sup class=”text-red”>*</sup></label> <div class=”col-sm-6 col-xs-12 col-md-8 col-lg-8″> <select class=”multi-select” id=”headoffice” name=”headoffice” data-placeholder=”Head Office Member”> <option value=””></option> <option value=”No” >No</option> … Read more
At last i have done this, please follow below code to implement crawl values form url of url. def parse(self, response): item=ProductItem() url_list = [content for content in response.xpath(“//div[@class=”listing”]/div/a/@href”).extract()] item[‘product_DetailUrl’] = url_list for url in url_list: request = Request(str(url),callback=self.page2_parse) request.meta[‘item’] = item yield request def page2_parse(self,response): item=ProductItem() item = response.meta[‘item’] item[‘product_ColorAvailability’] = [content for content … Read more
There are a few ways to solve this, but I believe this should work: std::vector<std::vector<int>> vec2D; int index = -1; // Identify the indices of the position vector and use that to identify the // correct indices of the vec. for (int i = 0; i != position.size(); ++i) { // if the value at … Read more
Do it like this example: try to run this set @fulfillStatus = 1; select CASE when @fulfillStatus = 0 then ‘open’ when @fulfillStatus = 1 then ‘processing’ when @fulfillStatus = 2 then ‘complete’ when @fulfillStatus = 5 then ‘Shipped’ when @fulfillStatus = 9 then ‘void’ else “None” END as “Order Status” 3 solved MySql case … Read more
Page 315 of Hacking: The Art of Exploitation does a good job explaining what that code does. solved What is this kind of shell code in c or c++? [closed]
What? A character is typically just that, one character. Not seven. You can do a wide character: char what=”12-4-30″; but I think that’s more bits than most compilers will let you have in a char, so it’s not going to work. If you meant a string of character, you should use snprintf(): char what[32]; snprintf(what, … Read more
You’ve programmed a canonical data-race. All the threads in your program are contending to update the variable count and there are no guarantees about the order in which each thread reads, updates, then writes the values to the variable. Whatever you may believe C++ does not guarantee that ++ is applied atomically. You should read … Read more
The solution is to use one (or more) helper classes associated with your activity; of course the helper class will have to see all the properties of your Activity for use them. A way that I found to do this is as follows: Suppose you have a MainActivity.java Create a class HelperActivity.java that accepts in … Read more
It doesn’t “expect static” anything – simply: you aren’t allowed to access this at this point, and number is implicitly this.number. Move the code to a constructor instead: public Foo() { number = “13”; a = Convert.ToString(number); } string number; int a; 2 solved Why method call on class level always expect static parameter?
I think that this code you could use int nl= image.rows; int nc= image.cols * image.channels(); for (int j=0; j<nl; j++) { uchar* data= image.ptr<uchar>(j); for (int i=0; i<nc; i++) { data[i]= data[i]/div*div + div/2; } } solved How can I access each pixel in OpenCV, perform an operation and return the new information to … Read more
The equivalent C# of your last line is: TextBox1.Text = String.Join(“”, Array.ConvertAll(bArr, byteValue => byteValue.ToString())); You replace the anonymous function with a lambda expression (byteValue => byteValue.ToString()) As I noted in my comment, this will print the decimal values of the bytes, so 0x00 will be printed as 1, and 0xFF will be printed as … Read more
I found a way to do what you are asking for: class AddableInt(int): def __call__(self, n): return AddableInt(self + n) def add(n): return AddableInt(n) add(5)(10)(20) # evaluates to 35 This works because the call to add(5) creates an AddableInt with a value of 5. No __init__ method was declared in AddableInt, so it just uses … Read more
you can send data to server by using Alamofire API. It’s documention and implemention all the stuff are mentioned in the following link. https://github.com/Alamofire/Alamofire Just install it using Pods and it’s very easy to implement. create Network Class and create following function inside it. func get_Request(currentView : UIViewController,action : NSString,completionHandler: (NSDictionary -> Void)) { print(“Url==>>>”,mainURl … Read more
Use arrays! Very small example: for($i=1; $i<=$iday; $i++){ echo “Day-$i<br />”; echo ‘<input type=”text” name=”i[‘.$i.’]” />’; echo ‘<textarea name=”d[‘.$i.’].'”></textarea>’; } Now you can loop through them when you post: foreach($_POST[‘i’] as $key=>$val ){ $sql2 = “INSERT INTO sight VALUES(”,'”. $_POST[‘i’][$key] .”‘,'”. $_POST[‘d’][$key] .”‘)”; } I’ve also changed the quotes. You should wrap attribute values in … Read more
