  • Make a simple animation in winforms using a loop

    - by Michael Quiles
    I need help making this loop to move a label move smoothly across the screen using count for the animation (its required). The labels location is currently in location 0,0 I'd like to make it go in a square right - down - left - back to its original position how can I accomplish this ? please give me an example using my code below. Thank You in advance. private void xAnimeTimer_Tick(object sender, EventArgs e) { int count; this.xAnimTimer.Stop(); for (count = 0; count <= 100; count++) { this.xAnimLabel.Left = count; } for (count = 0; count <= 150; count++) { this.xAnimLabel.Top = count; }

  • PHP to make vars and values part of array

    - by Chris
    I currently have this function to search and replace in a text file. // Input $ect = array('Visssa', 'Lisssa', 'her'); // Placeholders in the file $put = array('lname', 'fname', 'hisher'); // Replace the placeholders $oput = str_replace($put, $ct, 'tmpfile.txt'); This is not the full program but the idea is replace the values found in tmpfile.txt with the ones found in the $etc array. And it works flawlessly. But, what I need to do is get all passed vars (get/post) and then make the arrays so that the var is the value to replace and the value is the value to replace it with. So, if I sent the url http://xyz.com/?lname=tom&ogre=yes All instances of lname in the file would be replaces with tom and all instances of ogre would be replaced with yes. So somehow it just gets any/all variables passed in get/post and then the arrays showed above would cause the var to be replaced by the value in the file.

  • autofac's Func<T> to resolve named service

    - by ppiotrowicz
    Given registered services: builder.RegisterType<Foo1>().Named<IFoo>("one").As<IFoo>(); builder.RegisterType<Foo2>().Named<IFoo>("two").As<IFoo>(); builder.RegisterType<Foo3>().Named<IFoo>("three").As<IFoo>(); Can I retrieve named implementations of IFoo interface by injecting something like Func<string, IFoo ? public class SomeClass(Func<string, IFoo> foo) { var f = foo("one"); Debug.Assert(f is Foo1); var g = foo("two"); Debug.Assert(g is Foo2); var h = foo("three"); Debug.Assert(h is Foo3); } I know I can do it with Meta<, but I don't want to use it.

  • In Python, is it better to use list comprehensions or for-each loops?

    - by froadie
    Which of the following is better to use and why? Method 1: for k, v in os.environ.items() print "%s=%s" % (k, v) Method 2: print "\n".join(["%s=%s" % (k, v) for k,v in os.environ.items()]) I tend to lead towards the first as more understandable, but that might just be because I'm new to Python and list comprehensions are still somewhat foreign to me. Is the second way considered more Pythonic? I'm assuming there's no performance difference, but I may be wrong. What would be the advantages and disadvantages of these 2 techniques? (Code taken from Dive into Python)

  • VB.NET 2008 Application crashing during Do Loop

    - by RedHaze
    I am writing an application to compare each item on listbox1 to all items on listbox2. If the item is found, then remove it from both lists. The goal is to only have the items that were not found remain on both lists. The problem is, the application just hangs and I never get any results. I looked at my code several times and I cannot figure out what's going on (programming noob I know...). Can anybody help me with this? Code Snippet: Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim a As String Dim b As String Dim y As String For i As Integer = 0 To ListBox1.Items.Count - 1 a = ListBox1.Items(i) y = 1 Do While y = 1 For x As Integer = 0 To ListBox2.Items.Count - 1 b = ListBox2.Items(x) Dim res As Int16 = String.Compare(a, b) If res = 0 Then y = 0 ListBox2.Items.Remove(i) ListBox2.Items.Remove(x) ElseIf x = ListBox1.Items.Count Then Exit Do End If Next Loop Next End Sub

  • php multidimensional array if loop

    - by user1091558
    I have a multidimensional array like this array[value][1][1] Now i would like to implement if loop like this if ($value = array[value][1][1]) { echo "It works"; } Now it works if i assign the values like [1][1],[2][1]. Is it possible to compare the whole array. I mean if the array looks like array[value][1][1],array[value][2][1],..........,array[value][n][1] It works should be echoed. I tried like this. if ($value = array[value][][]) { echo "It works"; } But its not working. Can anyone give me the correct syntax?

  • Animation with CGPoint in for loop

    - by user1066524
    I'm trying to do an animation where when a person clicks from point A to Point B on screen the object should slowly slide straight across (horizontally) from point A to Point B. I tried doing a for loop with something like: for (CGFloat i=previousPoint.x; i <= newPoint.x; i++){ [UIView animateWithDuration:10 delay:0 options:nil animations:^ { [magnifier removeFromSuperview]; magnifier = [[MagnifierView alloc] init]; CGPoint np = {i, newPoint.y}; magnifier.viewToMagnify = imageView; magnifier.touchPoint = np; [imageView addSubview:magnifier]; [magnifier setNeedsDisplay]; } completion:^(BOOL finished) { }]; } but for some reason it is moving it way up and then eventually to point B. sort of in a weird curve. how can I do this correctly?

  • When is a Transient-scope object Deactivated in Ninject?

    - by nwahmaet
    When an object in Ninject is bound with InTransientScope(), the object isn't placed into the cache, since it's, er, transient and not scoped to anything. When done with the object, I can call kernel.Release(obj); this passes through to the Cache where it retrieves the cached item and calls Pipeline.Deactivate using the cached entry. But since transient objects aren't cached, this doesn't happen. I haven't been able to figure out where (or who) performs the deactivation for transient objects. Or is the assumption that transient objects are only ever activated, and that if I want a deactivateable object, I need to use some other scope?

  • Python Continue Loop

    - by Rob B.
    I am using the following code from this tutorial (http://jeriwieringa.com/blog/2012/11/04/beautiful-soup-tutorial-part-1/). from bs4 import BeautifulSoup soup = BeautifulSoup (open("43rd-congress.html")) final_link = soup.p.a final_link.decompose() trs = soup.find_all('tr') for tr in trs: for link in tr.find_all('a'): fulllink = link.get ('href') print fulllink #print in terminal to verify results tds = tr.find_all("td") try: #we are using "try" because the table is not well formatted. This allows the program to continue after encountering an error. names = str(tds[0].get_text()) # This structure isolate the item by its column in the table and converts it into a string. years = str(tds[1].get_text()) positions = str(tds[2].get_text()) parties = str(tds[3].get_text()) states = str(tds[4].get_text()) congress = tds[5].get_text() except: print "bad tr string" continue #This tells the computer to move on to the next item after it encounters an error print names, years, positions, parties, states, congress However, I get an error saying that 'continue' is not properly in the loop on line 27. I am using notepad++ and windows powershell. How do I make this code work?

  • Loop through non-integer rows using SQL

    - by Jesse
    I know how to accomplish my task with .NET, but I wanted to do this just in SQL. I need to loop through all of the rows where the primary key is somewhat arbitrary. It can be a number or a series of letters, and probably any number of unusual things. I know I could do something like this... DECLARE @numRows INT SET @numRows = (SELECT COUNT(pkField) FROM myTable) DECLARE @I INT SET @I = 1 WHILE (@I <= @numRows) BEGIN --Do what I need to here SET @I = @I + 1 END ...if my rows were indexed in a contiguous fashion, but I don't know enough about SQL to do that if they're not. I keep coming across the use of "cursors," but I come across just as much reading about avoiding cursors. I found this SO solution but I'm not sure if that's what I'm needing? I appreciate any ideas.

  • Why use a "do while" loop?

    - by Stanni
    Hi, I've never understood why using a do while loops is necessary. I understand what they do, Which is to execute the code that the while loop contains without checking if the condition is true first. But isn't the below code: do{ document.write("ok"); } while(x == "10"){ document.write("ok"); } The exact same as: document.write("ok"); while(x == "10"){ document.write("ok"); } Maybe I'm being very stupid and missing something obvious out but I don't see the benefit of using do while over my above example.

  • javascript var declaration within loop

    - by Trouts
    hello, /*Test scope problem*/ for(var i=1; i<3; i++){ //declare variables var no = i; //verify no alert('setting '+no); //timeout to recheck setTimeout(function(){ alert('test '+no); }, 500); } it alerts "setting 1" and "setting 2" as expected, but after the timeout it outputs "test 2" twice - for some reason the variable "no" is not reset after the first loop... i've found only an "ugly" workaround... /*Test scope problem*/ var func=function(no){ //verify no alert('setting '+no); //timeout to recheck setTimeout(function(){ alert('test '+no); }, 500); } for(var i=1; i<3; i++){ func(i); } Any ideas on how to workaround this problem in a more direct way? or is this the only way?

  • Loop through different sets of unique permutations

    - by user558610
    Hi I'm having a hard time getting started to layout code for this problem. I have a fixed amount of random numbers, in this case 8 numbers. R[] = { 1, 2, 3, 4, 5, 6, 7, 8 }; That are going to be placed in 3 sets of numbers, with the only constraint that each set contain minimum one value, and each value can only be used once. For example: R1[] = { 1, 4 } R2[] = { 2, 8, 5, 6 } R3[] = { 7, 4 } I need to loop through all possible combinations of a set R1, R2, R3. Order is not important, so if the above example happened, I don't need R1[] = { 4, 1 } R2[] = { 2, 8, 5, 6 } R3[] = { 7, 4 } NOR R1[] = { 2, 8, 5, 6 } R2[] = { 7, 4 } R3[] = { 1, 4 } What is a good method?

  • how Two elements - IMG - DIV when hover over IMG show/hide the DIV - added with hover hide/show on i

    - by Jan Fosgerau
    Im very new to the wonder that is jquery. and i just figure out how to make my img buttons show/hide with a opacity difference (as such) <script type="text/javascript"> <![CDATA[ $(".ExcommKnap").mouseover(function () { $(this).stop().fadeTo('fast', 0.5, function(){}) }); $(".ExcommKnap").mouseout(function () { $(this).stop().fadeTo('fast', 1.0, function(){}) }); ]]> </script> which is good and all. but i also need to make the button when hovered over show text just above it that is specific to that button. i made these here elements that are looped in a for each. <div style="top:10px; width:755px;text-align:right; position:absolute; "> <div id="Page-{@id}" class="headlinebox"> <xsl:value-of select="@nodeName"/> </div> </div> <a href="{umbraco.library:NiceUrl(@id)}"> <img class="ExcommKnap" src="{$media/data[@alias='umbracoFile']}" /> </a> i need to make the individual text appear when hovered over its button. hence i have the id="page-{@id}" looped out along and need to get this place in the jquery code i presume. so when i hover over a img class="ExcommKnap" it makes the correct text visible. But i need the div id="page-{id}" to be invisible to begin with on pageload and then visible when its button is being hovered over. can anyone help ?

  • Parallel.For(): Update variable outside of loop

    - 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. 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()); My guess is that the threads are trying to update "sum" at the same time. Is there an obvious way around it?

  • "...redeclared as different kind of symbol"?

    - by CodeNewb
    #include <stdio.h> #include <math.h> double integrateF(double low, double high) { double low = 0; double high = 20; double delta_x=0; double x, ans; double s = 1/2*exp((-x*x)/2); for(x=low;x<=high;x++) delta_x = x+delta_x; ans = delta_x*s; return ans; } It says that low and high are "redeclared as different type of symbol" and I don't know what that means. Basically, all I'm doing here (READ: trying) is integrating from low (which I set to 0) to high (20) to find the Riemann sum. The for loop looks kinda trippy too...I'm so lost.
