  • How to get the set events of a control?

    - by Jack
    It's possible via C# code get an list of methods/delegates that was set to Control? let me explain better.. For example. Assuming some definitions like this: foo.Click += (a, b) => { ... } //.. foo.Click += (A,B) => { ... } And a megic method: var baa = foo.GetEvents("Click"); Returns baa[0] points to (a, b) => { ... } baa[1] points to (A,B) => { ... } My scenery: I make and add dynamically event to some controls inside a loop. I want depending to a boolean value a event of control of index one,will removed by using control.Click -= baa[1] or something like this. I hope this is clear for your. Thanks in advance.

  • PHP from database and query

    - by Kyle R
    I have a table: id, affiliate Each time somebody clicks a link, a new row is inserted, ID being the ID of the page, and affiliate being the ID of the affiliate. For example: Page ID: 9 Affiliate ID: 1 Page ID: 9 Affiliate ID: 2 Page ID: 9 Affiliate ID: 3 I only have 3 affiliates. I want to select this information, and group them by affiliate, for the ID. I have tried this query: SELECT COUNT(*) FROM table WHERE id = '9' GROUP BY affiliate It works fine when I do it in php my admin, how do I get the info in PHP? I have tried: $q = mysql_query("SELECT COUNT(*) FROM table WHERE id = '" . $id . "' GROUP BY affiliate"); $r = mysql_fetch_array($q); When trying to print the data onto the page, I am only getting one result. Do I need to use a foreach/while loop to get all 3? How would I go about doing this? Thank you!

  • Parallel.For(): Different results for simple addition

    - by TSS
    I'm just looking in to the new .NET 4.0 features. With that, I'm attempting a simple calculation using Parallel.For and a normal for(x;x;x) loop. However, I'm getting different results about 50% of the time (no code change). long sum = 0; Parallel.For(1, 10000, y => { sum += y; }); Console.WriteLine(sum.ToString()); sum = 0; for (int y = 1; y < 10000; y++) { sum += y; } Console.WriteLine(sum.ToString()); Surely I'm missing something simple or do not completely understand the concept. My guess is that the threads are trying to update "sum" at the same time. If so, is there an obvious way around it?

  • Create MVC 5 Combo Box from CRM Entities?

    - by SpaceCowboy74
    I am working on an MVC 5 App that pulls data from Dynamics CRM 5. The Data I am getting back is an IQueryable of type Account (The CRM Entity class auto generated by CrmSvcUtil). I am retrieving all of the items and can loop through them with code like this: @foreach (var item in Model.ToList()) { <tr> <td> @item.AccountId </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> </tr> } The problem is, I would like to instead put them in a drop down list. I can't figure out what the syntax is to put these in a DropDown is. Any suggestions?

  • How to assign variable dynamically to php list function

    - by ravisoni
    What I am doing that I want to generate a list based on how many items are in an array, so I have counted the items and loop over them, create a number based var and construct a string $var which contains $a1,$a2.... and assigns the $var to list list($var) and tried to access $a1 but it gives me the error "Undefined variable: a1" Is there any other way to do it? Here is my code: $arr = array('1','2','3'); $listsize = count($arr); $var=''; for($i=1;$i<=$listsize;$i++){ $var.='$a'.$i; if($i!=$listsize){ $var.=','; } } list($var) = $arr; echo $a1;

  • Implementing an iterator over binary tree using C++ 11

    - by user1459339
    I would like to create an iterator over the binary tree so as to be able to use range-based for loop. I understand I ought to implement the begin() and end() function first. Begin should probably point to the root. According to the specification, however, the end() functions returns "the element following the last valid element". Which element (node) is that? Would it not be illegal to point to some "invalid" place? The other thing is the operator++. What is the best way to return "next" element in tree? I just need some advice to begin with this programming.

  • What are some Coldfusion (mx7 and greater) "Gotchas" that I should know about?

    - by jakeonrails
    I just spent half the day troubleshooting what is apparently a rather famous gotcha for Coldfusion MX7 and below: The nested query loop bug: Where you are required to reference the current_row of the outer query or else you will only see the first record. For example: <cfloop query="outer"> <cfloop query="innner"> <p>#outer.field#</p><!--- this won't work, you'll only get the first row ---> <p>#outer.field[current_row]#</p><!--- you must do this instead ---> </cfloop> </cfloop> Are there any other ways in which ColdFusion does not work in the obvious way?

  • Visual Basic 2013 String Replacement

    - by user3707612
    I found this code that replaces a string in a text file. But, I am trying to make it so that it replaces several strings in a text file. My.Computer.FileSystem.WriteAllText("C:\windows\PrinterList2.txt", My.Computer.FileSystem.ReadAllText("C:\windows\PrinterList.txt").Replace("IT", "ADM-IT"), False) For example, I need it to replace "IT" with "ADM-IT" and "AR" with "ADM-AR" and possibly a hundred or so more. How can I get it to loop to do them all? Running this line of code over and over just overwrites the file with the last item for replacement. Thanks in advance.

  • Make array from $_POST values

    - by cbarg
    Let's start telling that I'm passing an x amount of variables via post from a form. Let's name them menu_category_1, menu_category_2, ..., menu_category_x, plus, maybe, menu_category_new (I'm using an if empty to check this last one variable). To make things easier I'm also sending the parameter $key (amount of variables starting from 0). Now I need to set them into a new variable $menu_category (array), which is going to be imploded and then update my database. How do I set up that new $menu_category variable to be an array containing all my variables named in the beginning? I was thinking of using a for loop but I can't come up with something useful. Thanks!!!

  • Simple C++ classes question

    - by Without me Its just Aweso
    Its been a long time since i've done C++ and I'm running into some trouble with classes referencing eachother. right now I have something like: a.h class a { public: a(); bool skeletonfunc(b temp); } ==================== b.h class b { public: b(); bool skeletonfunc(a temp); } since each one needs a reference to the other i've found I cant do a #include of eachother at the top or i end up in a weird loop of sorts with the includes. So how can I make it so that a can use b and vice versa with out making a cyclical #include problem. thanks!

  • Can I un-assign (clear) all fields of an instance?

    - by Roman
    Is there a simple way to clear all fields of an instance from a an instance? I mean, I would like to remove all values assigned to the fields of an instance. ADDED From the main thread I start a window and another thread which controls state of the window (the last thread, for example, display certain panels for a certain period of time). I have a class which contains state of the window (on which stage the user is, which buttons he already clicked). In the end, user may want to start the whole process from the beginning (it is a game). So, I decided. So, if everything is executed from the beginning, I would like to have all parameter to be clean (fresh, unassigned). ADDED The main thread, creates the new object which is executed in a new thread (and the old thread is finished). So, I cannot create a new object from the old thread. I just have a loop in the second thread.

  • DatePicker with ShowUpDown set to true

    - by mhar
    I set the datepicker ShowUpDown to true. I notice that every time it reaches JANUARY of the following year it is throwing an error. Year, Month, and Day parameters describe an un-representable DateTime. reading on MSDN, it says that month should be between 1 and 12. So my guess is after the month of December, which is 12, when a user increase it again it will become 13, hence, throwing an error. Is is possible to loop this? From December(12) to January(1) instead of increasing it to 13.

  • Putting a variable inside a string (python)

    - by Gish
    Hi I am quite new to python and this is probably quite a basic question but the help would be much appreciated. I would like to put an int within a string. This is what I am doing at the moment.. end = smooth(data,window_len=40) plot.plot(time[0:len(end)],end) plot.savefig('hanning(40).pdf') #problem line I have to run the program for several different numbers instead of the two 40's. So I'd like to do a loop but inserting the variable like this doesn't work: plot.savefig('hanning',num,'.pdf') Thanks!

  • Select photo while keep the order

    - by wong2
    I have a list of photo on the page, each have an unique id, user can click on them to toggle select the photo, when they click the submit button, I need to send the array of selected photo ids to the back end, in the order that the photo was selected. I think that the fastest way to track if a photo is selected is to use an object that use photo id as key, like: var selected = { "6272861": true, "6272888": true } when the user unselect a photo, I just need to delete selected["6272861"]. But this will ignore the order, if I use an array to keep the selected photos: var selected = ["6272861", "6272888"]; then when I need to unselect a photo, I have to loop through the array and delete the item. Is there better ways? thanks.

  • Object still linked (referenced) after selecting it out of list?

    - by djerry
    Hey guys, I was wondering, and i'm not really sure, but help me out here. If you have a List items, and there's one object you need to change a property of it. Say myClass has a string property "status". I'm searching my list with a for-loop and i get my object so i do myClass item = items[i]; if i want to change the "status" property, i do this for example : item.Status = "new status"; My question/issue is this: is "item" still linked to the list item, so that if i execute the line above, it will be changed in the list as well without having to set this : items[i] = item; Hope this is clear. Thanks in advance.

  • $.each - wait for jSON request before proceeding

    - by GaaayLooord
    I have an issue with the below code: the jQuery.each is speeding on without waiting for the JSON request to finish. As a result, the 'thisVariationID' and 'thisOrderID' variables are being reset by the latest iteration of a loop before they can be used in the slower getJSON function. Is there a way to make each iteration of the the .each wait until completion of the getJSON request and callback function before moving on to the next iteration? $.each($('.checkStatus'), function(){ thisVariationID = $(this).attr('data-id'); thisOrderID = $(this).attr('id'); $.getJSON(jsonURL+'?orderID='+thisOrderID+'&variationID='+thisVariationID+'&callback=?', function(data){ if (data.response = 'success'){ //show the tick. allow the booking to go through $('#loadingSML'+thisVariationID).hide(); $('#tick'+thisVariationID).show(); }else{ //show the cross. Do not allow the booking to be made $('#loadingSML'+thisVariationID).hide(); $('#cross'+thisVariationID).hide(); $('#unableToReserveError').slideDown(); //disable the form $('#OrderForm_OrderForm input').attr('disabled','disabled'); } }) })

  • Select_related() backwards relation - auto model population

    - by Nick
    Hi. If I have the following model: class Contact(models.Model) name = models.CharField(max_length=100) ... class ContactAddress(models.Model) line1 = models.CharField(max_length=100) line2 = models.CharField(max_length=100) ... contact = models.ForeignKey(Contact) I now want to grab all Contacts and for the address to be auto populated. What would be the best way to do this? The only way I have found so far is to filter out the Contacts I want and loop around each contact and assign this to Contact.addresses. I then use this for outputting each Contacts address within a template. Is there a better way of doing this? Select_related() almost does what I want, but doesn't seem to be able to work in the opposite direction. Thanks in advance for your help on this one!

  • can this code be shortened or improved?

    - by user2816683
    Can this be shortened/improved? I'm trying to make a password checker in python. Could the if's be put into a for loop? And if so, how? pw = input("Enter password to test: ") caps = sum(1 for c in pw if c.isupper()) lower = sum(1 for c in pw if c.islower()) nums = sum(1 for c in pw if c.isnumeric()) scr = ['weak', 'medium', 'strong'] r = [caps, lower, nums] if len(pw) < 6: print("too short") elif len(pw) > 12: print("too long") if caps >= 1: if lower >= 1: if nums >= 1: print(scr[2]) elif nums < 1: print("your password is " + scr[1]) elif lower < 1: print("your password strength is " + scr[0]) elif caps < 1: print("your password strength is " + scr[1]) Thanks for any suggestions :D

  • How to apply Seq map function?

    - by netmatrix01
    Hello All, I been recently playing with F# . I was wondering instead of using a for loop to generate a sequence to element which are multiplied with every other element in the list how can I use a Seq map function or something similar to generate something like below. So for e.g. I have a list [1..10] I would like to apply a fun which generates a result something like [(1*1); (1*2);(1*3); (1*4); (1*5)......(2*1);(2*2);(2*3).....(3*1);(3*2)...] How can i achieve this ?. Many thanks for all you help.

  • functionality of cin in c++

    - by wyatt
    I'm a bit confused by the results of the following function: int main() { string command; while(1) { cin >> command; if(command == "end") return 0; else cout << "Could you repeat the command?" << endl; } return 0; } First of all - the output line ("could you...") repeats once for each individual word in the input (stored in command). So far as I can see, it should only be possible for it to happen once for each instance of the loop. Also, when the line 'if(command == "end")' is changed to 'if(command == "that's all")' it never triggers. A little testing suggested that all of the whitespace was removed from the command. Could someone explain to me what's going on here? Thanks
