A Popup Progress Window

一个包含bar和取消而且不需要资源弹出窗口

1.构造函数

CProgressWnd();
CProgressWnd(CWnd* pParent, LPCTSTR strTitle, BOOL bSmooth=FALSE);
BOOL Create(CWnd* pParent, LPCTSTR strTitle, BOOL bSmooth=FALSE);

参数说明：

pParent//父窗口
strTitle//窗口标题
bSmooth//是否平滑

2.方法属性

BOOL GoModal(LPCTSTR strTitle = _T("Progress"), BOOL bSmooth=FALSE);
                                    // Make window modal

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 SetRange(int nLower, int nUpper, int nStep = 1);
                                    // Set min, max and step size

void Hide();                        // Hide the window
void Show();                        // Show the window
void Clear();                       // Clear the text and reset the
                                    // progress bar
void SetText(LPCTSTR fmt, ...);     // Set the text in the text area

BOOL Cancelled()                    // Has the cancel button been pressed?

void SetWindowSize(int nNumTextLines, int nWindowWidth = 390);
                                    // Sets the size of the window
                                    // according to the number of text
                                    // lines specifed and the
                                    // desired window size in pixels.

void PeekAndPump(BOOL bCancelOnESCkey = TRUE);
                                    // Message pumping, with options of
                                    // allowing Cancel on ESC key.

SetWindowSize()默认显示四行

PeekAndPump()防止消息阻塞，在走进度过程中，相关操作可以继续执行，如esc取消，鼠标点击等等

3例子

通过GoModal()显示

CProgressWnd wndProgress(this, "Progress");

// wndProgress.GoModal(); // Call this if you want a modal window
wndProgress.SetRange(0,5000);
wndProgress.SetText("Processing...");

for (int i = 0; i < 5000; i++) {
    wndProgress.StepIt();
    wndProgress.PeekAndPump();

    if (wndProgress.Cancelled()) {
        MessageBox("Progress Cancelled");
        break;
    }
}

或者Create()

CProgressWnd wndProgress;

if (!wndProgress.Create(this, "Progress"))
    return;

wndProgress.SetRange(0,5000);
wndProgress.SetText("Processing...");
