Progress Control with Text

A smooth progress control with text

This is a simple CProgressCtrl derived class that allows text to be displayed on top of the progress bar in much the same way as many "Setup" programs display the progress of long operations.

The control is extremely simple and allows the same operations as a standard CProgressCtrl, as well as:

void SetShowText(BOOL bShow); Specifies whether or not the text for the control will be displayed during updates
COLORREF SetBarColor(COLORREF crBarClr = CLR_DEFAULT); Specifies the colour of the progress control bar, and returns the previous colour. If the colour is set as CLR_DEFAULT then the Windows default colour is used.
COLORREF GetBarColor(); Returns the colour of the progress control bar, or CLR_DEFAULT if the default Windows colours are being used.
COLORREF SetBarBkColor(COLORREF crBarClr = CLR_DEFAULT); Specifies the colour for the control's background, and returns the previous background colour. If the colour is set as CLR_DEFAULT then the Windows default colour is used.
COLORREF GetBarBkColor(); Returns the colour of the control's background, or CLR_DEFAULT if the default Windows colours are being used.
COLORREF SetTextColor(COLORREF crBarClr = CLR_DEFAULT); Specifies the colour of the text, and returns the previous colour. If the colour is set as CLR_DEFAULT then the Windows default colour is used.
COLORREF GetTextColor(); Returns the colour of the text, or CLR_DEFAULT if the default Windows colours are being used.
COLORREF SetTextBkColor(COLORREF crBarClr = CLR_DEFAULT); Specifies the background colour of the text, and returns the previous background colour. If the colour is set as CLR_DEFAULT then the Windows default colour is used.
COLORREF GetTextBkColor(); Returns the background colour of the text, or CLR_DEFAULT if the default Windows colours are being used.
BOOL SetShowPercent(BOOL bShow) Sets whether or not to show the percentage value of the bar, and returns the old value
DWORD AlignText(DWORD dwAlignment = DT_CENTER) Sets the text alignment and returns the old value
BOOL SetMarquee(BOOL bOn, UINT uMsecBetweenUpdate) Sets whether or not the progress control is in marquee mode, as well as the interval in milliseconds between steps of the marquee block
int SetMarqueeOptions(int nBarSize) Sets the size of the marquee as a percentage of the total control width

To set the text to be displayed use the standard CWnd::SetWindowText. If you call SetShowText(TRUE) but do not specify any window text using CWnd::SetWindowText, then the percentage fraction of progress will be displayed as default.

To use the control, just include a CProgressCtrl in your app as per usual (either dynamically or by using a dialog template) and change the variable type from CProgressCtrl to CTextProgressCtrl. (Make sure you include TextProgressCtrl.h)

At present the progress is only displayed as a smooth bar, and colours are strictly windows default colours. (These may be changed in the future versions.)

Thanks to Keith Rule for his CMemDC class.

Updates

Pete Arends went to town on the code. His updates:

  1. Set the font used to the parent window font
  2. Added SetTextColour() and GetTextColour() functions
  3. Added a bunch of message handlers, so the control now responds to the standard progress bar PBM_* messages. It is now possible to control the text progress control by sending messages to it. (works great from a worker thread).
  4. Added 2 new messages PBM_SETSHOWTEXT and PBM_SETTEXTCOLOR.
  5. Added an OnGetPos() handler. The function GetPos() now works!!

Thanks Pete!

3 Jan 05: Kriz has also extended the code with two basic methods that allow switching between the three alignment styles LEFT, CENTER and RIGHT - even on the fly if that's needed.

Changes to the code

  • Created a protected DWORD member m_dwTextStyle
  • Disabled all dwTextStyle variables in OnPaint or replaced them by
    m_dwTextStyle
  • Added two methods called AlignText and AlignTextInvalidate

Syntax

BOOL AlignText(DWORD aligment = DT_CENTER);
BOOL AlignTextInvalidate(DWORD aligment = DT_CENTER);

Params/Return:

"alignment" can be DT_LEFT, DT_CENTER (default) or DT_RIGHT. Using the invalidating version forces the control to repaint itself automatically. Both methods will return FALSE if a wrong alignment flag was given, otherwise they will return TRUE to the caller.

Thank you Kriz!

I've also updated the code so it compiles in VC7.X.

9 mar 06: Tony Bommarito has updated the code to include more settings for colours, made corrections to vertical text mode and added a new marquee mode.

26 Feb 07: Tony Mommarito has provided further updates:

  • Fixed bug where outside edge of progress bar wasn't drawn on XP when using an application manifest.
  • Added complete turn-off of marquee mode in a slightly different manner than that suggested in Robert Pickford message.
  • Fixed Unicode compile bug reported in dev75040 message.
  • Added three SLN and VCPROJ file sets; one each for VS2002, VS2003 and VS2005. By removing the VS… extension from the proper set, any of the three IDEs can be used.
