There are ways to do this in .NET using the ServiceController class and avoiding any interaction with the shell. You can find those here:MSDN ServiceController If you’d prefer to invoke a process through the CMD, you can create two separate processes and call either Thread.Sleep(milliseconds) or Task.Delay(milliseconds) to wait. Additionally, make sure that after you … Read more
# First declare a class (empty, in this case) class Pract: pass # Then instantiate it p1 = Pract() # Then set the attribute p1.age = 45 # Then print the attribute print(p1.age) You cannot instantiate a class before you finish declaring it. Everything you put inside class is part of the class definition. You … Read more

You can send a Refresh header to tell the page to refresh. Subtract 1 from the number of refreshes so it will count down. if (isset($_GET[‘refresh’]) && int($_GET[‘refresh’]) > 1) { $_GET[‘refresh’]–; header(“Refresh: $refresh_seconds; {$_GET[‘refresh’]}”); } where $refresh_seconds is how many seconds it should wait before refreshing. 1 solved php function to refresh page with … Read more
Foreward You should really use an html parser for this, but you seem to have creative control over the source string, and if it’s really this simple then the edge cases should be reduced. Description <img\s(?=(?:[^>=]|=”[^”]*’|=”[^”]*”|=[^'”][^\s>]*)*?\salt=[‘”]([^”]*)[‘”]?) (?:[^>=]|=”[^”]*’|=”[^”]*”|=[^'”\s]*)*”\s?\/?> This regular expression will do the following: find all the image tags require the image tag to have … Read more
You can use a query like this: SELECT t1.Title, t1.Url, t1.Description, t1.id FROM mytable AS t1 JOIN ( SELECT MIN(id) AS min_id FROM mytable GROUP BY title ) AS t2 ON t1.id = t2.min_id This will pick the record having the minimum id for each distinct value of Title. 3 solved SQL Query: Remove duplicates … Read more
Lets assume that set.seed(44) deaths<- 10:1 + sample.int(3, 10, replace = T) and spent<- seq(100, 550, by = 50 ) The very first thing you want to do when you get your data is literally to look at it. This can be done relatively painlessly with plot(spent, deaths) which yields So it looks like the … Read more
Your question is extremely vague with nothing for us to work with. But in any case, I just created an app requiring that logic so I would just share with you func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) { // Clear data if picture is repicked imageLocalURL = nil imageData = nil imageSelected = … Read more
You declared a as an array of int**, so *a is not a pointer to int but a pointer to pointer to int. Incrementing a pointer adds the size of the data type it points to, so ++*a advances the value at at a[0] by the size of a pointer. What you actually stored in … Read more
You can use Array.prototype.map() function. var o = {“tuple”:[{“old”:{“MST_VAS_TYPE”:{“MST_VAS_TYPE_ID”:”VAS_1000″,”VAS_TYPE_NAME”:”AMC”,”VAS_TYPE_DESC”:”Annual Maintenance Contract”,”CREATED_ON”:null,”CREATED_BY”:null,”MODIFIED_ON”:null,”MODIFIED_BY”:null,”@xmlns”:”http://services.vw.com/lpms/1.0/wsapp”}},”@xmlns”:”http://services.vw.com/lpms/1.0/wsapp”},{“old”:{“MST_VAS_TYPE”:{“MST_VAS_TYPE_ID”:”VAS_1001″,”VAS_TYPE_NAME”:”EW”,”VAS_TYPE_DESC”:”Extended Warranty”,”CREATED_ON”:null,”CREATED_BY”:null,”MODIFIED_ON”:null,”MODIFIED_BY”:null,”@xmlns”:”http://services.vw.com/lpms/1.0/wsapp”}},”@xmlns”:”http://services.vw.com/lpms/1.0/wsapp”},{“old”:{“MST_VAS_TYPE”:{“MST_VAS_TYPE_ID”:”VAS_1002″,”VAS_TYPE_NAME”:”COUPON”,”VAS_TYPE_DESC”:”Recall”,”CREATED_ON”:null,”CREATED_BY”:null,”MODIFIED_ON”:null,”MODIFIED_BY”:null,”@xmlns”:”http://services.vw.com/lpms/1.0/wsapp”}},”@xmlns”:”http://services.vw.com/lpms/1.0/wsapp”}],”@xmlns:SOAP”:”http://schemas.xmlsoap.org/soap/envelope/”,”@xmlns”:”http://services.vw.com/lpms/1.0/wsapp”}; a= o.tuple.map(function(val){ var inner = val[‘old’][‘MST_VAS_TYPE’]; var ret = {}; ret[inner[“MST_VAS_TYPE_ID”]] = inner[‘VAS_TYPE_NAME’]; return ret; }) sel = document.createElement(“select”); document.body.appendChild(sel); for (var index in a) { obj = a[index]; for (var prop in obj){ option = document.createElement(“option”); option.text = obj[prop]; option.value = prop; … Read more
For the future, it is better to post the relevant code here rather than post an image of all the code. You can start off with changing the cellForItemAtIndexPath implementation. You are downloading the image in the method (as a synchronous implementation). So unless the image is downloaded by contentsOfURL: and rendered, the cell won’t … Read more
