急啊,我照着书上的例子输入代码,编译通过了,但点"!"时程序没什么反应
也为Rich Edit 控件添加了变量m_RichEdit,也按书上的属性设置
代码我也加入了,如下(直接从光盘中复制的)
void COpenAndSaveDlg::OnButton1()
{
CFileDialog dlg(TRUE,NULL,NULL,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,
"All Files(*.*)|*.*| |",AfxGetMainWnd());
CString strPath,strText="";
if(dlg.DoModal() == IDOK)
{
strPath=dlg.GetPathName();
}
CFile file(strPath,CFile::modeRead);
char read[1000];
file.Read(read,1000);
for(int i=0;i<file.GetLength();i++)
{
strText += read[i];
}
file.Close();
m_RichEdit.SetWindowText(strText);
}
void COpenAndSaveDlg::OnButton2()
{
CFileDialog dlg(FALSE,NULL,NULL,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,
"All Files(*.*)|*.*| |",AfxGetMainWnd());
CString strPath,strText="";
char write[1000];
if(dlg.DoModal()==IDOK)
{
strPath=dlg.GetPathName();
if(strPath.Right(4)!=".txt")
strPath+=".txt";
}
CFile file(_T(strPath),CFile::modeCreate|CFile::modeWrite);
m_RichEdit.GetWindowText(strText);
strcpy(write,strText);
file.Write(write,strText.GetLength());
file.Close();
}
