我有一个类,它收集给定文件夹的 .txt 文件的所有路径并将它们存储到向量中。我使用的大多数功能都需要使用 TCHAR* 来获取/设置当前目录等。
该类如下所示:
typedef std::basic_string<TCHAR> tstring;
class folderManager
{
private:
TCHAR searchTemplate[MAX_PATH];
TCHAR directory[MAX_PATH];
WIN32_FIND_DATA ffd;
HANDLE hFind;
vector<tstring> folderCatalog;
vector<tstring> fileNames;
bool succeeded;
public:
// get/set methods and so on...
};
// Changed TCHAR* dir to tstring dir
void folderManager::setDirectory(tstring dir)
{
HANDLE hFind = NULL;
succeeded = false;
folderCatalog.clear();
fileNames.clear();
// Added .c_str()
SetCurrentDirectory(dir.c_str());
GetCurrentDirectoryW(MAX_PATH, directory);
TCHAR fullName[MAX_PATH];
StringCchCat(directory, MAX_PATH, L"\\");
StringCchCopy(searchTemplate, MAX_PATH, directory);
StringCchCat(searchTemplate, MAX_PATH, L"*.txt");
hFind = FindFirstFile(searchTemplate, &ffd);
if (GetLastError() == ERROR_FILE_NOT_FOUND)
{
FindClose(hFind);
return;
}
do
{
StringCchCopy(fullName, MAX_PATH, directory);
StringCchCat(fullName, MAX_PATH, ffd.cFileName);
folderCatalog.push_back(fullName);
fileNames.push_back(ffd.cFileName);
}
while (FindNextFile(hFind, &ffd) != 0);
FindClose(hFind);
succeeded = true;
}
这是我需要将 System::String^ 转换为 TCHAR* 的地方
private: System::Void dienuFolderisToolStripMenuItem_Click(System::Object^
sender, System::EventArgs^ e)
{
FolderBrowserDialog^ dialog;
dialog = gcnew System::Windows::Forms::FolderBrowserDialog;
System::Windows::Forms::DialogResult result = dialog->ShowDialog();
if (result == System::Windows::Forms::DialogResult::OK)
{
// Conversion is now working.
tstring path = marshal_as<tstring>(dialog->SelectedPath);
folder->setDirectory(path);
}
}
