  • Full Control Over CD/DVD burning

    - by Hypertext
    Suppose I want to burn just the 6000th byte(if thats not possible say the 10th sector) on a CDR without touching anyother region. Sounds possible but is there any tool to accomplish this. Yeah sure, there may be no clear point doing this but is this possible technically?. (Doesnt matter maintaining the CDFS, integrity or whatever standard here. Just the task.) It would be great to know if there are any software regarding this.

  • Commiting broken code to the repository for the purpose of backing it up

    - by Tim Merrifield
    I was just talking to another developer (more senior than I) and trying to convince him that we should implement continuous integration via Cruise Control. He told me that this will not work because he commits code that does not compile to the repository all the time for the purposes of backing it up. And that automated builds notifying us of failures would be just noise. Committing garbage to the repo sounds bad to me. But I was at a loss of words and didn't know what to say. What is the alternative? What's the best practice for backing up your code on another machine without adding a bunch of pointless revisions? BTW, our version control system is SVN and that probably won't change any time soon.

  • Control Windows 8 with a tablet

    - by Frantumn
    It seems much of Windows 8 is based on the idea that it will be running on tablets, and touch screen PCs. I like this, but I don't have a W89 tablet, or a touch PC yet. I'm running W8 on a laptop, and am wondering if there's any way of using my iPad2 as a touch interface with metro? Or another options that'd be nice is if there's a input device similar to Apple's "Magic Trackpad" that would allow me to use hand gestures instead of a mouse cursor when in metro apps. I've seen some cool videos of MS Smart Glass and it would seem that the capabilities are there. But it may just be too early on to do this? I'm not sure.

  • mfc tab control switch tabs

    - by MRM
    I created a simple tab control that has 2 tabs (each tab is a different dialog). The thing is that i don't have any idea how to switch between tabs (when the user presses Titlu Tab1 to show the dialog i made for the first tab, and when it presses Titlu Tab2 to show my other dialog). I added a handler for changing items, but i don't know how should i acces some kind of index or child for tabs. Tab1.h and Tab2.h are headers for dialogs that show only static texts with the name of the each tab. There may be an obvious answer to my question, but i am a real newbie in c++ and MFC. This is my header: // CTabControlDlg.h : header file // #pragma once #include "afxcmn.h" #include "Tab1.h" #include "Tab2.h" // CCTabControlDlg dialog class CCTabControlDlg : public CDialog { // Construction public: CCTabControlDlg(CWnd* pParent = NULL); // standard constructor // Dialog Data enum { IDD = IDD_CTABCONTROL_DIALOG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support // Implementation protected: HICON m_hIcon; // Generated message map functions virtual BOOL OnInitDialog(); afx_msg void OnSysCommand(UINT nID, LPARAM lParam); afx_msg void OnPaint(); afx_msg HCURSOR OnQueryDragIcon(); DECLARE_MESSAGE_MAP() public: CTabCtrl m_tabcontrol1; CTab1 m_tab1; CTab2 m_tab2; afx_msg void OnTcnSelchangeTabcontrol(NMHDR *pNMHDR, LRESULT *pResult); }; And this is the .cpp: // CTabControlDlg.cpp : implementation file // #include "stdafx.h" #include "CTabControl.h" #include "CTabControlDlg.h" #ifdef _DEBUG #define new DEBUG_NEW #endif // CAboutDlg dialog used for App About class CAboutDlg : public CDialog { public: CAboutDlg(); // Dialog Data enum { IDD = IDD_ABOUTBOX }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support // Implementation protected: DECLARE_MESSAGE_MAP() }; CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD) { } void CAboutDlg::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); } BEGIN_MESSAGE_MAP(CAboutDlg, CDialog) END_MESSAGE_MAP() // CCTabControlDlg dialog CCTabControlDlg::CCTabControlDlg(CWnd* pParent /*=NULL*/) : CDialog(CCTabControlDlg::IDD, pParent) { m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME); } void CCTabControlDlg::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); DDX_Control(pDX, IDC_TABCONTROL, m_tabcontrol1); } BEGIN_MESSAGE_MAP(CCTabControlDlg, CDialog) ON_WM_SYSCOMMAND() ON_WM_PAINT() ON_WM_QUERYDRAGICON() //}}AFX_MSG_MAP ON_NOTIFY(TCN_SELCHANGE, IDC_TABCONTROL, &CCTabControlDlg::OnTcnSelchangeTabcontrol) END_MESSAGE_MAP() // CCTabControlDlg message handlers BOOL CCTabControlDlg::OnInitDialog() { CDialog::OnInitDialog(); // Add "About..." menu item to system menu. // IDM_ABOUTBOX must be in the system command range.

  • jQuery nested sortables jumpy behaviour

    - by sebbie
    I want to allow user to drag and drop UI elements. I've 'container' and 'control', control may be in container, containers may include other containers (this is important requirement). I created simple prototype using jQuery. HTML: <div class="one"> <div class="control">Control 1</div> <div class="control">Control 2</div> <div class="control container"> Container drag area <div class="control">Subcontrol 1</div> <div class="control">Subcontrol 2</div> <div class="control">Subcontrol 3</div> <div class="control">Subcontrol 4</div> <div class="control">Subcontrol 5</div> <div class="control">Subcontrol 6</div> <div class="control">Subcontrol 7</div> <div class="control">Subcontrol 8</div> <div class="control">Subcontrol 9</div> </div> <div class="control">Control 3</div> Then I created sortables using jQueryUI: $('.one').sortable({ items: 'div.control', placeholder: 'placeholder', forcePlaceholderSize: true }); Now when I'm trying to drag "Subcontrol 8" and place it between "Subcontrol 2" and "Subcontrol 3" for example I'm getting jumpy effect, you can observe it here: http://jsbin.com/egipu4/2 Interesting thing is - when I remove ability to drag "container" then it becomes smooth and perfect (you can see this on jsbin example below "jumpy" example, you can't drag using "Container drag area" span). I tried different "nested" plugins and techniques, google'd for a long time and the only one that worked was on this page: (StackOverflow doesn't allow me to post more than one like, google for "Brian Swartzfager's Blog: Nested List Sort Demo" should be first, sorry!) But it does work great only in jQuery1.2 and very old jQueryUI. If I include latest jQuery (1.3/1.4) and UI (1.7/1.8) it gets jumpy as well. What am I doing wrong?

  • Best way to globally set every control's ValidationGroup property in an asp.net?

    - by Steve Flook
    I have a User Control with form items that is re-used considerably throughout a large web application, and up until this point the validation summary upon an invalid form submission is being handled by the .aspx that consumes the User Control. Now I need to set the ValidationGroup property at runtime for each of my form items controls (textboxes, lists, validators, etc). Rather than do it manually by setting each control I'm interested in iterating through all the controls in the User Control, detecting if that control has a ValidationGroup property, and setting it's value that way. Something like this: For Each ctrl As System.Web.UI.Control In Me.Controls ' so now what is the proper way to detect if this control has the ValidationGroup property Next Code sample in vb.net or c# works for me. Many thanks!

  • MVC 2 View Layout CSS Control Layout

    - by Cory Mathewson
    I'm new to a lot of what I'm trying to do with the development of a new MVC2 web application so this is a beginner question. I need to understand my options for control and content layout on a web page. I’m using MVC2 so I’m using Controllers, Views, ViewModels, and View Templates. What I need to spin up on…fast…is control the granular layout of controls and content on any particular view. Below I’ve pasted two examples of auto generated templates that illustrate my challenge. I see that layout is controlled by CSS in my Site.css document. In the first example I get a sequential flow of DisplayLabel and DisplayField. I prefer the adjacent layout of DisplayLabel on the same line as DisplayField produced from example 2. However, example 2 is too simple because the formatting is applied to the Label and the Field. I think the correct way to tackle this learning curve is Microsoft Expression but I don’t have personal bandwidth at the moment to tackle Expression. Can anyone point me to a resource that will expose me to lots of examples for CSS formatting? I have lots of syntax questions. For instance, I believe is referencing the Site.css but I can’t find a "display-label" section in Site.css. Example 1 <fieldset> <legend>Fields</legend> <div class="display-label">DocTitle</div> <div class="display-field"><%: Model.DocTitle %></div> <div class="display-label">DocoumentPropertiesID</div> <div class="display-field"><%: Model.DocumentPropertiesID %></div> Example 2 <h2>Title: <%: Model.DocTitle %></h2> <h2>Created: <%: Model.Created %></h2> <h2>Modified: <%: Model.Modified %></h2> <h2>Author: <%: Model.tbl_Author.Name %></h2> <h2>Genre: <%: Model.tbl_DocumentGenre.GenreName %></h2>

    - by Frank Schwieterman
    In the context of the TFS version control SDK (Microsoft.TeamFoundation.VersionControl), what exactly is deletionID? It is a property of Microsoft.TeamFoundation.VersionControl.Client.Item. It is also a parameter to some of the query methods on Microsoft.TeamFoundation.VersionControl.Client. I'm trying to figure out exactly what it means, and how it might impact queries.

  • iphone segmented control and uitableview

    - by Emma
    I have a UITableView with a segmented control at the top. When you tap on the different segments, I want the table to reload with a new different sized array. I have tried everything including [self.tableView reloadData]. When you click on a different tab now, it only changes the cells that are out of view and does not add any more. Any ideas??? Thanks.
