  • Stings Generation

    - by sikas
    Hi,I would like to know how can I create various string from some given characters eg: given characters: a, b I would like to generate the following strings: aa ab ba bb What I have thought of is having (for 2 inputs only) two for-loops one inside another, and then loop each to the number of inputs which in this case is 2 and the output strings will be 2*2 0 4 strings and as the number increases the number of output strings will increase by multiplying n*n (n-times)

  • Release edit in QTableWidget Cell

    - by Schomin
    Basically I am trying to give the enter key the same functionality as the return key has when editing a cell in a qtablewidget. If editing a cell and enter is pressed I want it to jump out of editing that cell just like return does. It feels like I've literally tried everything. I've even tried passing a return press event to qcoreapplication. It seems like if your editing a cell and you press a key to trigger an action it wont happen. That seems to be what the problem is and I'm not sure how to get around that. I've been setting up all of my keyboard shortcuts for this program as actions because it seems easier to set up. Is there another way to do this that would allow the key event to happen when editing a cell? Can anyone help out with this? Thank you in advance. Tried this. It didn't work for me. http://stackoverflow.com/questions/518447/how-can-i-tell-a-qtablewidget-to-end-editing-a-cell

  • What is used instead of SendMessage and PostMessage in Java to handle inter-thread communications?

    - by Kieveli
    I'm from a WinAPI / C++ background, and I'm curious as to what the Java world uses in place of a threaded message loop in a worker thread to handle communications and interactions between threads. The idea is to use a message pump in both the worker thread, and the main thread, and have them posting messages back and forth. This solution is very WinAPI / C++ centric, and probably not the preferred method of achieving this goal in Java. What is the 'Java' way to do something like this?

  • JQuery Checkbox generation

    - by Hash
    I have used the following code to generate some dynamic checkboxes. This works for the first time and adds the check box chk2 to the page and then after the trigger for the $('#newLink').click is not working. Please help me with this. <div id="chkBoxesDiv"> <input type="checkbox" id="chk1" ></input> <input id="answerText" type="text" size="30" ></input>&nbsp; <input type="button" value="add new" id="newLink"/> </div> $(document).ready(function(){ $('#newLink').click(function (event){ var i = 0; //To count the children $("#chkBoxesDiv").children().each(function(){ var child = $(this); if(child.is(":checkbox")){ i++; } }); //prevent action event.preventDefault(); //get textbox value to fill checkbox var text = $("#answerText").val(); alert(i); //if text not empty do stuff if(text != ""){ //add label $("#chk"+i).after("<label for=\"chk"+i+"\" id=\"lblchk"+i+"\">"+text+"</label>"); $("#newLink").remove(); $("#answerText").remove(); $("#lblchk1").after("<br /><input type=\"checkbox\" id=\"chk"+(1+i)+"\" ></input><input type=\"text\" id=\"answerText\" size=\"30\" ></input>&nbsp;<input type=\"button\" value=\"add new\" id=\"newLink\"/>"); } }); });

  • Exact cin equivalent function in python

    - by gkt.pro
    Suppose user enter this string at terminal 123 456 456 //then hit enter How do I scan these three (could be more) numbers in different variables in python Could be something like this: for i in range(1,n) m[i]=#WHAT FUNCTION SHOULD I PUT HERE In c++ we can easily use cin>>m[i] inside above loop to scan the variables. If i use input() or raw_input() , they would scan whole line in single variable.

  • IE ignores added onclick attribute

    - by user357034
    The Jquery code below works ok with firefox, Safari, Opera but not with IE. I kinda know why this isn't working in IE after reading a lot about it but I do not know how to fix it. My understanding (I think) is that this method will assign a attribute of "onclick" in IE rather than an event method. Therefore it will not fire in IE and the href fires instead which in this case is "#" which is exactly what is happening. What is the correct way of adding the onclick event. <a id="product_photo_zoom_url" href="/PhotoGallery.asp?ProductCode=9857%2D116%2D003" title="9857-116-003 Ignition box"><img id="product_photo" src="/v/vspfiles/photos/9857-116-003-2T.jpg" border="0" alt="9857-116-003 Ignition box" /></a> <br /><a id="product_photo_zoom_url2" href="/PhotoGallery.asp?ProductCode=9857%2D116%2D003" title="9857-116-003 Ignition box"> <img src="/v/vspfiles/templates/100/images/buttons/btn_largerphoto.gif" border="0"></a> var global_URL_Encode_Current_ProductCode; var global_Config_ProductPhotosFolder; var global_Current_ProductCode; var titleattr = $("a#product_photo_zoom_url").attr("title"); var picurl='tb_show(titleattr, \'/PhotoDetails.asp?ShowDESC=N&ProductCode=\' + global_URL_Encode_Current_ProductCode + \'&TB_iframe=true&height=600&width=520\');return false;' $("a#product_photo_zoom_url").attr('onclick', picurl); $("a#product_photo_zoom_url").attr('href', '#'); $("a#product_photo_zoom_url2").attr('onclick', picurl); $("a#product_photo_zoom_url2").attr('href', '#');

  • How to create a CPU spike with a bash command

    - by User1
    I want to create a near 100% load on a Linux machine. It's quad core system and I want all cores going full speed. Ideally, the CPU load would last a designated amount of time and then stop. I'm hoping there's some trick in bash. I'm thinking some sort of infinite loop.

  • Can't get my Jscrollpane working in my Jtextarea

    - by Bobski
    I've looked around quite a lot on google and followed several examples however I can't seem to get my JScrollPane working on a textarea in a JPanel. import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.lang.*; import javax.swing.event.*; class main { public static void main(String Args[]) { frame f1 = new frame(); } } class frame extends JFrame { JButton B = new JButton("B"); JButton button = new JButton("A"); JTextArea E = new JTextArea("some lines", 10, 20); JScrollPane scrollBar = new JScrollPane(E); JPanel grid = new JPanel (); frame() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(500,800); setTitle("Mobile Phone App"); setLocationRelativeTo(null); E.setLineWrap(true); E.setEditable(false); grid.add(button); button.addActionListener(new action()); grid.add(B); B.addActionListener(new action()); //grid.add(E); grid.getContentPane().add(scrollBar); add(grid); setVisible(true); } class action implements ActionListener { public void actionPerformed(ActionEvent e) { String V = E.getText(); if(e.getSource() == button) { E.setText(V + "A is pressed"); } if(e.getSource() == B) { E.setText(V + "B is pressed"); } } } } Would be great if someone can see where I am going wrong. I added JscrollPane in which I added the text area "e" in it.

  • Handling of data truncation in FUSE

    - by Vi
    I expect any good program should do all their reads and writes in a loop until all data written/read without relying that write will write everything (even with regular files). Am I right? Implemented simple FUSE filesystem which only allows reading and writing with small buffers, very often returning that it is written less bytes that in a buffer (using -o direct_io). Some programs work, some not. Are them buggy or programs should not expect truncated writes and reads from the regular files?

  • What is the display list in Flash 10? Array? Linked list?

    - by Typeoneerror
    I'm working on a game that has many elements on stage, so I'm looking to optimize my loops. I know that Vector is faster than looping an array, but I'm also in some cases using: while (i < numChildren) getChildAt(i) ...to update sprites. My question is when I use getChildAt, is that accessing an Array or Vector or linked list or other? Should I instead store references to my objects in a Vector and loop through that instead?

    How can I send data through a GTK callback? I've Googled, and with the information I found created this: #include <gtk/gtk.h> #include <stdio.h> void button_clicked( GtkWidget *widget, GdkEvent *event, gchar *data); int main( int argc, char *argv[]){ GtkWidget *window; GtkWidget *button; gtk_init (&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); button = gtk_button_new_with_label("Go!"); gtk_container_add(GTK_CONTAINER(window), button); g_signal_connect_swapped(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL); g_signal_connect(G_OBJECT(button), "clicked", G_CALLBACK(button_clicked),"test" ); gtk_widget_show(window); gtk_widget_show(button); gtk_main(); return 0; } void button_clicked( GtkWidget *widget, GdkEvent *event, gchar *data){ printf("%s \n", (gchar *) data); return; } But it just Segfaults when I press the button.

  • How to filter Wordpress posts using a hook in a plugin?

    - by Davide
    I'm creating a Wordpress plugin and, being a newbie in the development on this platform, I'm stuck on this problem. I'd like to have posts in the loop filtered by categories, defined by the user through an admin page. I would actually like to be able to modify query_post() parameters in the plugin, but the only trick I found is to re-run the query_post() with my user-defined criteria, thing that I would like to avoid. I'm sure the solution is evident, but can't find it!

  • I can't prevent key presses from changing a selected option in Firefox

    - by Anthony
    Using Firefox 3.5.7 The following test page should behave like Opera, Safari and Chrome. Key presses (arrows or 1-5) should have no effect (i.e. The events should be cancelled so that the number never changes from the initial default "3"). [I have separate working code for IE too]. Many thanks to anyone who can make it work? <html> <head> <title>Test</title> <script type='text/JavaScript'> function stop(evt) {evt.preventDefault(); evt.stopPropagation(); }; </script> </head> <body> <select onkeydown='stop(event);' onkeypress='stop(event);'> <option>1</option> <option>2</option> <option selected="selected">3</option> <option>4</option> <option>5</option> </select> </body> </html>

  • jQuery selectable() elements update values

    - by Josh
    Basically what I'm trying to do is update the value attribute of a hidden input field contained within the selected element when the selectable() UI stops running. If the element is selected, then the input's value should be the name attribute of that particular LI, whereas if the element is not selected, the value should be updated as empty. HTML Sample: <ul id="selector"> <li class="networkicon shr-digg" name="shr-digg"> <div></div> <label>Digg</label> <input type="hidden" value="" name="bookmark[]" /> </li> <li class="networkicon shr-reddit" name="shr-reddit"> <div></div> <label>Reddit</label> <input type="hidden" value="" name="bookmark[]" /> </li> <li class="networkicon shr-newsvine" name="shr-newsvine"> <div></div> <label>Newsvine</label> <input type="hidden" value="" name="bookmark[]" /> </li> </ul> Script Sample: $(function() { $("#selector").selectable({ filter: 'li', selected: function(event, ui) { $(".ui-selected").each(obj, function() { $(this).children('input').val($(this).attr('name')); }); }, unselected: function(event, ui) { $(".ui-selected").each(obj, function() { $(this).children('input').val(''); }); } }); });

  • Issue with dynamically loading a user control on button click

    - by Kumar
    I have a page in which I am loading a user control dynamically as follows: Default.aspx: <cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> </cc1:ToolkitScriptManager> <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder> Default.aspx.cs: protected void Page_Load(object sender, EventArgs e) { var ctrl = LoadControl("~/UserCtrl1.ascx"); ctrl.ID = "ucUserCtrl1"; PlaceHolder1.Controls.Add(ctrl); } Below is the code for UserCtrl1.ascx <asp:Label ID="Label1" runat="server"></asp:Label> <asp:Button ID="Button1" runat="server" Text="Button1" OnClick="Button1_Click" /> <br /> <asp:PlaceHolder ID="PlaceHolder2" runat="server"></asp:PlaceHolder> I am dynamically loading another user control when the Button1 is clicked UserCtrl1.ascx.cs protected void Button1_Click(object sender, EventArgs e) { Label1.Text = "UserControl - 1 button clicked!"; var ctrl = LoadControl("~/UserCtrl2.ascx"); ctrl.ID = "ucUserCtrl2"; PlaceHolder2.Controls.Add(ctrl); } Below is the markup for UserCtrl2.ascx <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:Label ID="Label2" runat="server"></asp:Label> <asp:Button ID="Button2" runat="server" Text="Button2" OnClick="Button2_Click" /> </ContentTemplate> </asp:UpdatePanel> UserCtrl2.ascx.cs protected void Button2_Click(object sender, EventArgs e) { Label2.Text = "UserControl - 2 button clicked!"; } After the page loads when I click the Button1 in UserCtrl1 the click event fires and I am able to see the Label1 text. It also properly loads the UserCtrl2, but when I click the Button2 in UserCtrl2 the click event dosent fire and even worse when I click the Button2 twice the UserCtrl2 control dissappears from the page. How can I fix this?

  • Storing a NTFS Security Descriptor in C

    - by Doori Bar
    My goal is to store a NTFS Security Descriptor in its identical native state. The purpose is to restore it on-demand. I managed to write the code for that purpose, I was wondering if anybody mind to validate a sample of it? (The for loop represents the way I store the native descriptor) This sample only contains the flag for "OWNER", but my intention is to apply the same method for all of the security descriptor flags. I'm just a beginner, would appreciate the heads up. Thanks, Doori Bar #define _WIN32_WINNT 0x0501 #define WINVER 0x0501 #include <stdio.h> #include <windows.h> #include "accctrl.h" #include "aclapi.h" #include "sddl.h" int main (void) { DWORD lasterror; PSECURITY_DESCRIPTOR PSecurityD1, PSecurityD2; HANDLE hFile; PSID owner; LPTSTR ownerstr; BOOL ownerdefault; int ret = 0; unsigned int i; hFile = CreateFile("c:\\boot.ini", GENERIC_READ | ACCESS_SYSTEM_SECURITY, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, NULL); if (hFile == INVALID_HANDLE_VALUE) { fprintf(stderr,"CreateFile() failed. Error: INVALID_HANDLE_VALUE\n"); return 1; } lasterror = GetSecurityInfo(hFile, SE_FILE_OBJECT, OWNER_SECURITY_INFORMATION , &owner, NULL, NULL, NULL, &PSecurityD1); if (lasterror != ERROR_SUCCESS) { fprintf(stderr,"GetSecurityInfo() failed. Error: %lu;\n", lasterror); ret = 1; goto ret1; } ConvertSidToStringSid(owner,&ownerstr); printf("ownerstr of PSecurityD1: %s\n", ownerstr); /* The for loop represents the way I store the native descriptor */ PSecurityD2 = malloc( GetSecurityDescriptorLength(PSecurityD1) * sizeof(unsigned char) ); for (i=0; i < GetSecurityDescriptorLength(PSecurityD1); i++) ((unsigned char *) PSecurityD2)[i] = ((unsigned char *) PSecurityD1)[i]; if (IsValidSecurityDescriptor(PSecurityD2) == 0) { fprintf(stderr,"IsValidSecurityDescriptor(PSecurityD2) failed.\n"); ret = 2; goto ret2; } if (GetSecurityDescriptorOwner(PSecurityD2,&owner,&ownerdefault) == 0) { fprintf(stderr,"GetSecurityDescriptorOwner() failed."); ret = 2; goto ret2; } ConvertSidToStringSid(owner,&ownerstr); printf("ownerstr of PSecurityD2: %s\n", ownerstr); ret2: free(owner); free(ownerstr); free(PSecurityD1); free(PSecurityD2); ret1: CloseHandle(hFile); return ret; }
