GUI 剖析之控件篇之 进度条

进度条控件：



执行步骤：
1. 拖放进度条控件至对话框
2. 执行以下代码（假设ID为：IDC_PROGRESS1）
#include "Commctrl.h"
#pragma comment(lib,"comctl32.lib")

设置进度条控件范围：
static LONGnMinPos=0, nMaxPos=100,nPos=0;
hwndPress=GetDlgItem(hDlg,IDC_PROGRESS1);
SendMessage(hwndPress,SBM_SETRANGE,nMinPos,nMaxPos
);
改变进度条进度位置：
SendMessage(hwndPress,PBM_SETPOS, (WPARAM)nPos,
0 );
设置进度条颜色：
SendMessage(hwndPress,PBM_SETBARCOLOR ,0,RGB(0,0,0));
设置进度条背景色：
SendMessage(hwndPress,PBM_SETBKCOLOR ,0,RGB(0,0,0));
设置进度条状态：
SendMessage(hwndPress,PBM_SETSTATE,PBST_NORMAL,0);//这里的PBST_PAUSED也可以是PBST_NORMAL或PBST_ERROR
还有的其他消息可以去参考MSDN.

ps:下面是我参考MSDN写的一个类，用于手动创建进度条（包含两个文件）
ProgressBarWhenEnter.h
