У меня есть приложение MFC. Это в основном просто копирование файлов с одного диска на другой. Когда я копирую большие файлы (более 1 ГБ) и нажимаю на окно, мое приложение зависает, но копирование продолжается в фоновом режиме. Кто-то сказал мне, что я должен использовать рабочий поток. Я использовал это, но это все еще зависает. Когда я копирую небольшие файлы, это нормально. Я не могу понять, в чем может быть проблема. Пожалуйста, помогите кому-нибудь!
Вот мой код:
void CGetFileListDlg::OnBnClickedButtonGetFileList()
{
//here i'm doing file list comparing
AfxBeginThread( CopyThread, &Tstruct ); //here i call my thread and give a struct to it as a paramter, which contains, which file i have to copy
}
UINT CopyThread( LPVOID pParam )
{
UINT uiMaxPass = 3;
UINT uiPAssCount = 0;
int i = 0;
threadstruct *Test = (threadstruct*)(pParam);
CGetFileListDlg* ptr = (CGetFileListDlg*)Test->ez ;
struct address
{
char *from;
char *to;
int current;
};
struct address Address;
for ( i = 0; i < Test->diff; i++ )
{
