Showing progress bar in a status bar pane

An easy way to add a progress control to a status bar

Sample Image

Adding a CProgressCtrl to the status bar has already been addressed by Brad Mann. His method involved modifying the status bar and messing around with the resource editor. I developed a separate CProgressBar class in order to allow the programmer to just drop in a progress bar whereever they wanted using a single "CProgressBar Bar(...)" declaration, which would initialise and display itself and clean up after itself after it was done. The progress bar can also be created once (say as a member variable) and reused multiple times. This new version of the progress bar also resizes itself if the status bar size changes.

The progress bar lets you specify a message (displayed to the left of the bar) and a Progress Control bar in the any pane of your applications status bar (if it has one - thanks to Patty You for a bug fix on that one). The message for the progress bar can be changed at any time, as can the size and range of the bar.


CProgressBar(LPCTSTR strMessage, int nSize=100, int MaxValue=100, BOOL bSmooth=FALSE, int nPane=0);
BOOL Create(LPCTSTR strMessage, int nSize=100, int MaxValue=100, BOOL bSmooth=FALSE, int nPane=0);

Construction is either via the constructor or a two-step process using the constructor and the "Create" function. "strMessage" is the message to be displayed, "nSize" is the percentage width of the status bar that will be occupied by the bar (including the text), and "MaxValue" is the maximum range of the bar.

"bSmooth" will only be effective if you have the header files and commctrl32.dll from IE 3.0 or above (no problems for MS VC 5.0). It specifies whether the progress bar will be smooth or chunky.


    BOOL Success()                      // Construction successful?

    COLORREF SetBarColour(COLORREF clrBar);  // Set Bar colour, returns previous
    COLORREF SetBkColour(COLORREF clrBar);   // Set background colour, returns previous

    int  SetPos(int nPos);              // Same as CProgressCtrl
    int  OffsetPos(int nPos);           // Same as CProgressCtrl
    int  SetStep(int nStep);            // Same as CProgressCtrl
    int  StepIt();                      // Same as CProgressCtrl
    void Clear();                       // Clear the status bar
    void SetRange(int nLower, int nUpper, int nStep = 1);
                                        // Set min, max and step size
    void SetText(LPCTSTR strMessage);   // Set the message
    void SetSize(int nSize);            // Set the bar size

To use the bar, just do something like:

    CProgressBar Bar("Testing", 40, 1000);
    for (int i = 0;  i <  1000; i++) 
        // perform operation
or it can be done two stage as:
    CProgressBar bar;
    bar.Create("Processing", 40, 1000);
    for (int i = 0; i < 1000; i++) 
        //    perform operation 
    for  (int i = 0;  i <  1000; i++) 
        // perform operation
        PeekAndPump();    // Message pump

In the above case, PeekAndPump() is a function which simply peeks and pumps messages, allowing user interaction with the window during a lengthy process. If the window size changes during the processing, the progress bar size will alsow change.

This article was updated by Michael Martin (allowing the progress bar can now be placed in any pane of the status bar). A further update by YoSilver has fixed an issue that occurs in multithreaded apps. Yet Another Update by Alex Paterson allows you to specify which statusbar you wish the bar to appear in.
