vc application 中的7788

自定义消息:

#define UM_PROGRESS WM_USER+1



BEGIN_MESSAGE_MAP(CMainDialog, CDialog)



ON_MESSAGE(UM_PROGRESS,OnProgress)



END_MESSAGE_MAP()



//消息处理函数

LRESULT CMainDialog::OnProgress(WPARAM wParam,LPARAM lParam)
{

　　

　　return 0;

}





{

　　dlg->SendMessage(UM_PROGRESS);

}

程序中需要用到系统托盘的功能，在 http://www.vckbase.com/document/viewdoc/?id=677 中得到了最简单的方法～水～

几个简单函数

线程相关的东东：

private:

public:

读写2进制文件

#include "afx.h"



CStdioFile file;
file.Open(logfilepath,CFile::modeCreate|CFile::modeWrite|CFile::typeBinary);
for()

    CString strLogVal;

file.Close();




CString strText = L"";
CString szLine = L"";
CStdioFile file1;
file1.Open(this->logfiledir,CFile::modeRead|CFile::typeBinary);
//逐行读取字符串
while( file1.ReadString( szLine ) )
{
    strText += szLine+'\n';
}
//关闭文件
file1.Close();

用CSpreadSheetEx读excel貌似dao方式

    ss.OpenSheet(strExcelSheetName);
    int iTotalRowNum = ss.GetRowCounts();
