程序变一变，过程很麻烦！！！请高手支招！

请问vc++在单文档模板下，怎么编程实现用文件对话框或者列表控件，一次打开多个文件，并将每个文件的内容读倒数组中。
我开始使用文件对话框做的，只能读出一个文件现在想改成能读多个文件的，msdn里的说明每看明白，请高手指点！！
我开始大体上是这样做的：
void CTestView::OnRead()
{
CFileDialog file(TRUE);
if(file.DoModal()==IDOK)
{
CString str;
str=file.GetFileName();
char buffer[80]=m_file.ReadFile(str);/////////////读文件函数
}
}
要读多个文件的话，数组是不是还要扩大，或者变成二维的？

你说的跟单文档程序和对话框程序没啥关系，你的功能在单文档程序和对话框程序都能实现，其实质在于让允许
文件对话框一次选择打开多个文件，参开下面的文档：


According to the CFileDialog overview:

To allow the user to select multiple files, set the OFN_ALLOWMULTISELECT flag before calling DoModal. You need to supply your own filename buffer to accommodate the returned list of multiple filenames. Do this by replacing m_ofn.lpstrFile with a pointer to a buffer you have allocated, after constructing the CFileDialog, but before calling DoModal. Additionally, you must set m_ofn.nMaxFile with the number of characters in the buffer pointed to by m_ofn.lpstrFile.

for example,

CFileDialog dlg( TRUE, NULL, NULL, OFN_ALLOWMULTISELECT, NULL, NULL );
DWORD MAXFILE = 100000; //2562 is the max by default
dlg.m_ofn.nMaxFile = MAXFILE;
char* pc = new char[MAXFILE];
dlg.m_ofn.lpstrFile = pc;
dlg.m_ofn.lpstrFile[0] = NULL;

看下面的代码：
CFileDialog dlg( TRUE, NULL, NULL, OFN_ALLOWMULTISELECT, NULL, NULL );
DWORD MAXFILE = 100000; //2562 is the max by default
dlg.m_ofn.nMaxFile = MAXFILE;
char* pc = new char[MAXFILE];
dlg.m_ofn.lpstrFile = pc; // 此处进行替换
dlg.m_ofn.lpstrFile[0] = NULL; // 此处是清零操作

[zhyp011]

CFileDlg dlg( TRUE,_T("TXT"),_T("*.TXT"),

OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT|OFN_ALLOWMULTISELECT,

_T("文本文件 (*.txt)|*.txt所有文件 (*.*)|*.*|"));

if(dlg.DoModal()!=IDOK) return FALSE;

while (pos != NULL)

{

CString strPath = dlg.GetNextPathName(pos);

if (strPath.Find(":\\\\") == 1 && strPath.GetLength() > 4)

{

CString temp;

temp = strPath.Left(3);

temp += strPath.Mid(4);

strPath = temp;

}

谢谢啊！我的msdn没有下面的例子。Do this by replacing m_ofn.lpstrFile with a pointer to a buffer you have allocated, after constructing the CFileDialog, but before calling DoModal.这句没看明白。怎么实现指针更替，还有从数组里顺序读出文件名啊？请指教！
