FileDialog选择多个文件

FileDialog对话框中，选择多个文件的示例代码片段。

LPCTSTR filters = "Bitmap Files (*.bmp) |*.bmp|Bitmap Config Files (*.txt)|*.txt|All Files (*.*)|*.*||";

// 选项中设置 OFN_ALLOWMULTISELECT
CFileDialog fileDialog(TRUE, NULL, NULL,
    OFN_ALLOWMULTISELECT | OFN_ENABLESIZING | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY,
    filters);

// 设置OFN属性
const int MAX_FILES = 100;
const int BUFFER_SIZE = (MAX_FILES * (MAX_PATH + 1)) + 1;
char* buffer = (char*)malloc(BUFFER_SIZE);
fileDialog.GetOFN().lpstrFile = buffer;
fileDialog.GetOFN().nMaxFile = MAX_FILES;

if (IDCANCEL == fileDialog.DoModal()) return;

// 遍历取到的每个文件
POSITION position = fileDialog.GetStartPosition();
CString tempFileName;
while (position != NULL) {  
    tempFileName =fileDialog.GetNextPathName(position);
    m_bitmapFiles.Add(tempFileName/*fileDialog.GetNextPathName(position)*/);
}

free(buffer);
