文件浏览和图片浏览
此示例代码展示如何使用文件浏览，图片浏览，文件保存和文件选择。
图片浏览:
IMzSelect *pSelect = NULL;
IPhotoViewer *pImage = NULL;
CoInitializeEx(NULL, COINIT_MULTITHREADED );
if ( SUCCEEDED( CoCreateInstance( CLSID_PhotoView, NULL,CLSCTX_INPROC_SERVER ,IID_MZ_PhotoViewer,(void **)&pImage ) ) )
{
if( SUCCEEDED( pImage->QueryInterface( IID_MZ_Select, (void**)&pSelect ) ) )
{
pImage->SetParentWnd( m_hWnd );
pImage->SetSelectPhotoMode( SELECT_NORMAL );
pImage->SetCurrentImageFileName( L"\\Disk\\Temp.jpg " );//因为内部会做截屏操作，所以后缀名为.jpg和.png
pSelect->Invoke();
pSelect->Release();
}
pImage->Release();
}
CoUninitialize();
文件选择:
IMzSelect *pSelect = NULL;
IFileBrowser *pFile = NULL;
CoInitializeEx(NULL, COINIT_MULTITHREADED );
if ( SUCCEEDED( CoCreateInstance( CLSID_FileBrowser, NULL,CLSCTX_INPROC_SERVER ,IID_MZ_FileBrowser,(void **)&pFile ) ) )
{
if( SUCCEEDED( pFile->QueryInterface( IID_MZ_Select, (void**)&pSelect ) ) )
{
TCHAR file[ MAX_PATH ] = { 0 };
pFile->SetParentWnd( m_hWnd );
pFile->SetOpenDirectoryPath( L"\\Disk\\EBook" ); //如果不调用此函数则默认为根目录
pFile->SetExtFilter( L"*.txt;*.rar;" );
pFile->SetOpenDocumentType(DOCUMENT_SELECT_SINGLE_FILE); //应用根据需求进行文档打开方式的设置
if( pSelect->Invoke() )
{//各应用根据自己需求获取文档的返回值
_tcscpy( file, pFile->GetSelectedFileName() );
std::wstring displayText = L"选择的文件为:";
displayText += file;
MzMessageBoxEx( m_hWnd, displayText.c_str(), L"Test" );
displayText.clear();
}
pSelect->Release();
}
pFile->Release();
}
CoUninitialize();
::InvalidateRect( m_hWnd, NULL, FALSE );
::UpdateWindow( m_hWnd );
文件保存：
IMzSave *pSave = NULL;
IFileBrowser *pFile = NULL;
CoInitializeEx(NULL, COINIT_MULTITHREADED );
if ( SUCCEEDED( CoCreateInstance( CLSID_FileBrowser, NULL,CLSCTX_INPROC_SERVER ,IID_MZ_FileBrowser,(void **)&pFile ) ) )
{
if( SUCCEEDED( pFile->QueryInterface( IID_MZ_Save, (void**)&pSave ) ) )
{
pFile->SetParentWnd( m_hWnd );
pFile->SetOpenDocumentType(DOCUMENT_SAVE_FILES); //应用根据需求进行文档打开方式的设置
pFile->SetOpenDirectoryPath( L"\\Disk\\EBook" );
if( pSave->Invoke() )
{//提供路径给应用进行保存操作
TCHAR saveDir[ MAX_PATH ] = { 0 };
_tcscpy( saveDir, pFile->GetSaveFileDirectory() );
std::wstring displayText = L"保存的路径为:";
displayText += saveDir;
MzMessageBoxEx( m_hWnd, displayText.c_str(), L"Test" );
displayText.clear();
}
pSave->Release();
}
pFile->Release();
}
CoUninitialize();
选择多个文件：
IMzSelect *pSelect = NULL;
IFileBrowser *pFile = NULL;
CoInitializeEx(NULL, COINIT_MULTITHREADED );
if ( SUCCEEDED( CoCreateInstance( CLSID_FileBrowser, NULL,CLSCTX_INPROC_SERVER ,IID_MZ_FileBrowser,(void **)&pFile ) ) )
{
if( SUCCEEDED( pFile->QueryInterface( IID_MZ_Select, (void**)&pSelect ) ) )
{
TCHAR file[ MAX_PATH ] = { 0 };
pFile->SetParentWnd( m_hWnd );
pFile->SetOpenDirectoryPath( L"\\Disk" ); //如果不调用此函数则默认为根目录
pFile->SetOpenDocumentType(DOCUMENT_SELECT_FILES); //应用根据需求进行文档打开方式的设置
if( pSelect->Invoke() )
{//各应用根据自己需求获取文档的返回值
int selectedDirectoryCount = pFile->GetSelectedDirectoryCount();
int selectedFileCount = pFile->GetSelectedFileCount();
TCHAR temp[ MAX_PATH ] = { 0 };
wsprintf( temp, L"文件%d个, 目录%d个",selectedFileCount, selectedDirectoryCount );
MzMessageBoxEx( m_hWnd,temp, L"Test" );
for ( int i = 0; i < selectedDirectoryCount; i++ )
{
_tcscpy( file, pFile->GetSelectedDirectoryPath( i ) );
std::wstring displayText = L"选择的目录为:";
displayText += file;
MzMessageBoxEx( m_hWnd, displayText.c_str(), L"Test" );
displayText.clear();
}
for ( int i = 0; i < selectedFileCount; i++ )
{
_tcscpy( file, pFile->GetSelectedFilePath( i ) );
std::wstring displayText = L"选择的文件为:";
displayText += file;
MzMessageBoxEx( m_hWnd, displayText.c_str(), L"Test" );
displayText.clear();
}
}
pSelect->Release();
}
pFile->Release();
}
