I wold create a control named for example InfoProgresBar  that provide this functionality with a label or two  Main Job  Current Job  and ProgressBar and use it instead of that ProgressBar

Alliteratively you can try placing a Label control and placing it on top of the progress bar control  Then you can set whatever the text you want to the label  I haven t done this my self  If it works it should be a simpler solution than overriding onpaint

I have written a no blinking flickering TextProgressBar You can find the source code here  https   github com ukushu TextProgressBar  WARNING  It s a little bit buggy  But still  I think it s better than another answers here  As I have no time for fixes  if you will do sth with them  please send me update by some way   Thanks  Samples

I tried placing a label with transparent background over a progress bar but never got it to work properly  So I found Barry s solution here very useful  although I missed the beautiful Vista style progress bar  So I merged Barry s solution with http   www dreamincode net forums topic 243621-percent-into-progress-bar  and managed to keep the native progress bar  while displaying text percentage or custom text over it  I don t see any flickering in this solution either  Sorry to dig up and old thread but I needed this today and so others may need it too   public enum ProgressBarDisplayText       Percentage      CustomText    class ProgressBarWithCaption   ProgressBar         Property to set to decide whether to print a   or Text     private ProgressBarDisplayText m DisplayStyle      public ProgressBarDisplayText DisplayStyle           get   return m DisplayStyle            set   m DisplayStyle   value                 Property to hold the custom text     private string m CustomText      public string CustomText           get   return m CustomText            set               m CustomText   value              this Invalidate                         private const int WM PAINT   0x000F      protected override void WndProc ref Message m                base WndProc m            switch  m Msg                case WM PAINT                  int m Percent   Convert ToInt32  Convert ToDouble Value    Convert ToDouble Maximum     100                   dynamic flags   TextFormatFlags VerticalCenter   TextFormatFlags HorizontalCenter   TextFormatFlags SingleLine   TextFormatFlags WordEllipsis                   using  Graphics g   Graphics FromHwnd Handle                         using  Brush textBrush   new SolidBrush ForeColor                              switch  DisplayStyle                                case ProgressBarDisplayText CustomText                                  TextRenderer DrawText g  CustomText  new Font  Arial   Convert ToSingle 8 25   FontStyle Regular   new Rectangle 0  0  this Width  this Height   Color Black  flags                                   break                              case ProgressBarDisplayText Percentage                                  TextRenderer DrawText g  string Format   0     m Percent   new Font  Arial   Convert ToSingle 8 25   FontStyle Regular   new Rectangle 0  0  this Width  this Height   Color Black  flags                                   break                                                                                      break

I have created a InfoProgressBar control which uses a TransparentLabel control  Testing on a form with a Timer  I get some slight glitches displaying the text every 30-40 value changes if using a timer interval of less than 250 milliseconds  probably because of the time required to update the screen is greater than the timer interval    It would be possible to modify UpdateText method to insert all the calculated values into CustomText but it isn t something that I have needed yet  This would remove the need for the DisplayType property and enumerate   The TransparentLabel class was created by adding a new UserControl and changing it to inheriting from Label with the following implementation   using System  using System ComponentModel  using System Drawing  using System Windows Forms   namespace Utils GUI       public partial class TransparentLabel   Label                  hide the BackColor attribute as much as possible             setting the base value has no effect as drawing the            background is disabled          Browsable false            EditorBrowsable EditorBrowsableState Never           public override Color BackColor                       get                               return Color Transparent                            set                                                protected override CreateParams CreateParams                       get                               CreateParams cp   base CreateParams                  cp ExStyle    0x20      WS EX TRANSPARENT                 return cp                                   public override string Text                       get                               return base Text                            set                               base Text   value                  if Parent    null  Parent Invalidate Bounds  false                                    public override ContentAlignment TextAlign                       get                               return base TextAlign                            set                               base TextAlign   value                  if Parent    null  Parent Invalidate Bounds  false                                    public TransparentLabel                         InitializeComponent                 SetStyle ControlStyles Opaque  true               SetStyle ControlStyles OptimizedDoubleBuffer  false                base BackColor   Color Transparent                     protected override void OnMove EventArgs e                        base OnMove e               RecreateHandle                       protected override void OnPaintBackground PaintEventArgs pevent                           do nothing                     I did not make any changes to the related designer code but here it is for completeness   namespace Utils GUI       partial class TransparentLabel                    lt summary gt               Required designer variable               lt  summary gt          private System ComponentModel IContainer components   null                lt summary gt               Clean up any resources being used               lt  summary gt               lt param name  disposing  gt true if managed resources should be disposed  otherwise  false  lt  param gt          protected override void Dispose bool disposing                        if disposing  amp  amp   components    null                                 components Dispose                              base Dispose disposing                       region Component Designer generated code               lt summary gt               Required method for Designer support -

AVOID FLICKERING TEXT  The solution provided by Barry above is excellent  but there s is the  flicker-problem    As soon as the Value is above zero the OnPaint will be envoked repeatedly and the text will flicker   There is a solution to this  We do not need VisualStyles for the object since we will be drawing it with our own code   Add the following code to the custom object Barry wrote and you will avoid the flicker        DllImportAttribute  uxtheme dll        private static extern int SetWindowTheme IntPtr hWnd  string appname  string idlist        protected override void OnHandleCreated EventArgs e                SetWindowTheme this Handle                   base OnHandleCreated e           I did not write this myself  It found it here  https   stackoverflow com a 299983 1163954  I ve testet it and it works

Just want to point out something on  codingbadger answer  When using  ProgressBarRenderer  you should always check for  ProgressBarRenderer IsSupported  before using the class  For me  this has been a nightmare with Visual Styles errors in Win7 that I couldn t fix  So  a better approach and workaround for the solution would be   Rectangle clip   new Rectangle rect X  rect Y   int Math Round   float Value   Maximum    rect Width   rect Height   if  ProgressBarRenderer IsSupported    ProgressBarRenderer DrawHorizontalChunks g  clip   else   g FillRectangle new SolidBrush this ForeColor   clip     Notice that the fill will be a simple rectangle and not chunks  Chunks will be used only if ProgressBarRenderer is supported

You will have to override the OnPaint method  call the base implementation and the paint your own text   You will need to create your own CustomProgressBar and then override OnPaint to draw what ever text you want   Custom Progress Bar Class  namespace ProgressBarSample    public enum ProgressBarDisplayText       Percentage      CustomText    class CustomProgressBar  ProgressBar         Property to set to decide whether to print a   or Text     public ProgressBarDisplayText DisplayStyle   get  set           Property to hold the custom text     public String CustomText   get  set         public CustomProgressBar                    Modify the ControlStyles flags           http   msdn microsoft com en-us library system windows forms controlstyles aspx         SetStyle ControlStyles UserPaint   ControlStyles AllPaintingInWmPaint  true              protected override void OnPaint PaintEventArgs e                Rectangle rect   ClientRectangle          Graphics g   e Graphics           ProgressBarRenderer DrawHorizontalBar g  rect           rect Inflate -3  -3           if  Value  gt  0                           As we doing this ourselves we need to draw the chunks on the progress bar             Rectangle clip   new Rectangle rect X  rect Y   int Math Round   float Value   Maximum    rect Width   rect Height               ProgressBarRenderer DrawHorizontalChunks g  clip                         Set the Display text  Either a   amount or our custom text         string text   DisplayStyle    ProgressBarDisplayText Percentage   Value ToString           CustomText            using  Font f   new Font FontFamily GenericSerif  10                          SizeF len   g MeasureString text  f                  Calculate the location of the text  the middle of progress bar                 Point location   new Point Convert ToInt32  rect Width   2  -  len Width   2    Convert ToInt32  rect Height   2  -  len Height   2                 Point location   new Point Convert ToInt32  Width   2  - len Width   2   Convert ToInt32  Height   2  - len Height   2                    The commented-out code will centre the text into the highlighted area only  This will centre the text regardless of the highlighted area                 Draw the custom text             g DrawString text  f  Brushes Red  location                         Sample WinForms Application  using System  using System Linq  using System Windows Forms  using System Collections Generic   namespace ProgressBarSample       public partial class Form1   Form               public Form1                         InitializeComponent                   Set our custom Style    or text              customProgressBar1 DisplayStyle   ProgressBarDisplayText CustomText              customProgressBar1 CustomText    Initialising                      private void btnReset Click object sender  EventArgs e                        customProgressBar1 Value   0              btnStart Enabled   true                     private void btnStart Click object sender  EventArgs e                        btnReset Enabled   false              btnStart Enabled   false               for  int i   0  i  lt  101  i                                   customProgressBar1 Value   i                     Demo purposes only                 System Threading Thread Sleep 100                       Set the custom text at different intervals for demo purposes                 if  i  gt  30  amp  amp  i  lt  50                                        customProgressBar1 CustomText    Registering Account                                      if  i  gt  80                                        customProgressBar1 CustomText    Processing almost complete                                       if  i  gt   99                                        customProgressBar1 CustomText    Complete                                                btnReset Enabled   true
