  • Problem displaying the Message box in MFC

    - by kiddo
    I have a simple MFC program which displays the progressbar..I used the below code to display the progress bar.. HWND dialogHandle = CreateWindowEx(0,WC_DIALOG,L"Proccessing...",WS_OVERLAPPEDWINDOW|WS_VISIBLE, 600,300,280,120,NULL,NULL,NULL,NULL); HWND progressBarHandle = CreateWindowEx(NULL,PROGRESS_CLASS,NULL,WS_CHILD|WS_VISIBLE|PBS_MARQUEE,40,20,200,20, dialogHandle,(HMENU)IDD_PROGRESS,NULL,NULL); while(FALSE == testResult) { MSG msg; SendMessage(progressBarHandle, PBM_SETRANGE, 0, MAKELPARAM( 0, 100 ) ); SendMessage(progressBarHandle,PBM_SETPOS,0,0); ShowWindow(progressBarHandle,SW_SHOW); Sleep(50); if(TRUE == myCondition)//myCondition is a bool variable which is decalred globally { DestroyWindow(dialogHandle); AfxMessageBox(L"Test Success"); } } when I execute the above code..the message box displays only after a mouseover event.like if I move the mouse the message box will display if not it will not display until i move the mouse. And also while the progressbar is running if I try to move the progress bar window..it displays a windows background at the place of displacement and also in the new region or sometimes its getting stuck.Please help me with this!

  • Problem displaying contents of a class in Java

    - by LuckySlevin
    My problem is i have a class and in it there is a list of elements of another class. public class Branch { private ArrayList<Player> players = new ArrayList<Player>(); String brName; public Branch() {} public void setBr(String brName){this.brName = brName;} public String getBr(){return brName;} public ArrayList<Player> getPlayers() { return players; } public void setPlayers(ArrayList<Player> players) { this.players =new ArrayList<Player>(players); } } public class Player { private String name; private String pos; private Integer salary; private Integer number; public Player(String name, String pos, Integer salary, Integer number) { this.name = name; this.pos = pos; this.salary = salary; this.number = number; } public Player(){} public String getName() { return name; } public String getPos() { return pos; } public Integer getSalary() { return salary; } public Integer getNumber() { return number; } public void setName(String name) { this.name = name; } public void setPos(String pos) { this.pos = pos; } public void setSalary(Integer salary) { this.salary = salary; } public void setNumber(Integer number) { this.number = number; } } My problem is to print the players of a Branch with their name,pos,salary,number. For this i tried this simply : String p1,p2; int a1,a2; p1 = input.readLine(); p2 = input.readLine(); a1 = Integer.parseInt(input.readLine()); a2 = Integer.parseInt(input.readLine()); players[0].setName(p1); players[0].setPos(p2); players[0].setSalary(a1); players[0].setNumber(a2); ptmp.add(players[0]); myBranch[0].setPlayers(ptmp); System.out.println(myBranch[0].brName + " " + myBranch[0].getPlayers()); I wrote this just to try how to display. I created an array of Players, and Branches so they already defined. The problem is getPlayers() doesn't give me any result. What is the way to do this?

  • Character problem at displaying the result of a query

    - by rahmivolkan
    I am not good at jsp but I wondered what can cause such a problem when every other strings are displayed well: a JSP file queries information of people by their name at Contact (MS Exchange). the query returns the full info of the person; and the first, last names are printed. Last names with apostrophes (Ex: O'reilly) aren't displayed at all. what can be possible solutions? Thanks in advance P.S. I know the way of asking is not suitable but, I need information from people who had such a problem before.

  • HTML5 Drag and Drop styles not displaying on Windows Server 2003

    - by NoR
    I'm working on a file upload utility based on Valum's Ajax-Uploader. The idea is similar to the Gmail attachment process. The user should be able to drag a file from the desktop into the browser window and onto the file upload area to get it to upload. This works fine in the browsers that support this functionality (Firefox 3.6+, Chrome 7+). The problem I'm running into are the styles that should be re-drawn when the user: Drags the file anywhere in the browser Drags the file into the upload area I have tested in the exact same browser versions on WinXP, Vista, and Win7. The appropriate styles are redrawn. However, in Windows Server 2003, they do not. In Win2003, when I inspect the div that should be redrawn via Firebug, the "drop-area" and "drop-area-active" classes are applied correctly. Firebug even shows the correct style declarations, but the changes are never visible. The only difference between FF and Chrome that I'm able to spot is that in Chrome, the "drop-area-active" style is displayed for a split second when the user drops the file. I'm not positive that it is a Windows2003 issue, but that's the only OS in which I'm able to recreate the bug.

  • Displaying Data on the Windows Form

    - by The.Anti.9
    I'm searching files and returning lines that include the search text, and I'm not really sure the best way to display the information I get. Every time I get a match, I want to show, in some sort of control, the File it came from, and the whole text line. (aka streamreader.ReadLine() result). First I tried just putting it all in a read-only text box, but it doesn't have a scroll bar. What is the best form control to help me display this data neatly?

  • C# String builder, displaying data nicely spaced out.

    - by Sef
    Hello, I am wondering how exactly can i order my date nicely in a stringbuilder? Meaning something equal to ("{0,2}", ....) to space the data nicely out. I do not want to use consolewrites of any kind, so the class can be re-used in a form, console code etc... Currently i am using " " for the spacing, but in overall it does not give a proper display. (it messed up when i have numbers with more then 1 digit) public override string ToString() { StringBuilder builder = new StringBuilder(); foreach (int value in tabel) { builder.Append(value); // should have something similiar to ("{0,2}", ....) builder.Append(" "); // should have something similiar to ("{0,2}", ....) } builder.Append("(top:"); builder.Append(top); builder.Append(")"); return builder.ToString(); }/*ToString*/ Regards.

  • GWT : Composite not displaying

    - by animatrix30
    I have a this code for the layout : grid = new Grid(15, 15); tiles = new Tile[15][15]; for (int i = 0; i != 15; i++) { for (int j = 0; j != 15; j++) { tiles[i][j] = new Tile('a'); grid.setWidget(i, j, tiles[i][j]); tiles[i][j].setVisible(true); } } initWidget(grid); I know it is working, because if I change the tile, by a Button, it works well. Now my Tile class : public class Tile extends Composite { char character; public Tile (Character c) { this.character = c; buildWidget(); } private void buildWidget() { Label l = new Label(this.character+""); initWidget(l); } Why does all tiles are not displayed ? Thanks for your help !

  • Displaying Query Results Horizontally

    - by AndyD273
    I am wondering if it is possible to take the results of a query and return them as a CSV string instead of as a column of cells. Basically, we have a table called Customers, and we have a table called CustomerTypeLines, and each Customer can have multiple CustomerTypeLines. When I run a query against it, I run into problems when I want to check multiple types, for instance: Select * from Customers a Inner Join CustomerTypeLines b on a.CustomerID = b.CustomerID where b.CustomerTypeID = 14 and b.CustomerTypeID = 66 ...returns nothing because a customer can't have both on the same line, obviously. In order to make it work, I had to add a field to Customers called CustomerTypes that looks like ,14,66,67, so I can do a Where a.CustomerTypes like '%,14,%' and a.CustomerTypes like '%,66,%' which returns 85 rows. Of course this is a pain because I have to make my program rebuild this field for that Customer each time the CustomerTypeLines table is changed. It would be nice if I could do a sub query in my where that would do the work for me, so instead of returning the results like: 14 66 67 it would return them like ,14,66,67, Is this possible?

  • Rendering HTML in rails without actually displaying it

    - by Kevin Whitaker
    Hello all, My current project requires me to assemble a .zip file containing HTML and text-only templates for a user to download, for importing into an email marketing program. I've inherited this project, and currently the code uses a "fake" model (that is a model that does not directly correlate to a database table), in which it stores the entire template in a string, using dynamic variables to populate certain areas. The "fake" model then has a method for creating a zip file. It seems to me that there has to be a better way to do this. I was wondering if there was a way to move the template into a .erb/haml file, and then write a method that would populate the file in preparation for being zipped up? Basically, is there a way to render an HTML and text file, without actually having to display them? Thanks for any help.

  • displaying search results with two or more queries

    - by fusion
    in my search form, if the user types 'good', it displays all the results which contain the keyword 'good'. however if the user types in 'good sweetest', it displays no results because there is no record with the two words appearing together; BUT appearing in an entry at different places. for example, the record says: A good action is an ever-remaining store and a pure yield the user types in 'good', it will show up this record, but if the user types in 'good' + 'pure', it will not show anything. what i would like is that if the user types in 'good' + 'pure' it should records containing these keywords highlighting them. search.php code: $search_result = ""; $search_result = $_POST["q"]; $search_result = trim($search_result); //Check if the string is empty if ($search_result == "") { echo "<p class='error'>Search Error. Please Enter Your Search Query.</p>" ; exit(); } if ($search_result == "%" || $search_result == "_" || $search_result == "+" ) { echo "<p class='error1'>Search Error.

  • jQuery image loop not displaying any images

    - by user1871097
    I'm trying to create a very basic image gallery in jQuery. The goal is to have 3 images fade in and out in a sequential order. So image 1 is displayed, fades to image 2 etc. then the whole thing loops again. My HTML code so far is as follows: <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Slider</title> <style type="text/css"> .slider{ width: 2848px; height: 2136px; overflow: hidden; margin: 30px auto; } .slider img{ width:2848px; height:2136px; display:none; } </style> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script> <script src="Slider2.js"></script> </head> <body onload="Slider2"();> <div class="slider"> <img id="1" src="31.jpg" border="0" alt="city"/> <img id="2" src="2vrtigo2.jpg" border="0" alt="roof"/> <img id="3" src="3.jpg" border="0" alt="sea"/> </div> </body> And the jQuery code looks like this: function Slider2() { var total = $(".slider img").size(); for (i=1; i<=total; i+=1) { $(".slider #"+i).fadeIn(600); $(".slider #"+i).delay(2000).hide; }} A quick syntactical note, I've also tried using i++ in the last argument of the For Loop. The result of this code is a blank, white page. I know some of the HTML is being compiled because the enormous 2848x2136 div creates scroll bars on the browser. If anyone could help me out, that would be greatly appreciated. Obviously I'm relatively new to web programming and would love some insight into why this isn't working. Thanks!
