Many tools are out there to get file dates, but this tool will set whatever date you specify to any file(s) or folder(s). By studying this tool, you will learn about:
When you click Apply, the new date & time you had specified will be set to the selected file(s) or folder(s). SetFileTime API is used to set date and time to a file/folder. Setting date and time to folders and files within a folder is a tricky thing. Here I have used FindFirstFile and FindNextFile to find all folders and files recursively while setting new date & time to them. Here is the code for it:
// its an independent function, will set the date and time /// its a core function in this tool int SetFileDateTime(char *szFilePath, FILETIME ftCreated, FILETIME ftModified, FILETIME ftAccessed) { DWORD dwAttr; dwAttr = GetFileAttributes(szFilePath); if(g_bIgnoreAttrAndApply) {//to ignore mean resets the file/folder attributes to normal // and again it will be set back if(FILE_ATTRIBUTE_HIDDEN&dwAttr) if(!g_bAttrHidden) return 0; if(FILE_ATTRIBUTE_READONLY&dwAttr) if(!g_bAttrReadOnly) return 0; if(FILE_ATTRIBUTE_SYSTEM&dwAttr) if(!g_bAttrSystem) return 0; if(FILE_ATTRIBUTE_COMPRESSED&dwAttr) if(!g_bAttrCompressed) return 0; if(FILE_ATTRIBUTE_ENCRYPTED&dwAttr) if(!g_bAttrEncrypted) return 0; SetFileAttributes(szFilePath,FILE_ATTRIBUTE_NORMAL); } else {//if not to ignore, then the following //attributed file/folder can not be set to new file x date time if(FILE_ATTRIBUTE_HIDDEN&dwAttr) return 0; if(FILE_ATTRIBUTE_READONLY&dwAttr) return 0; if(FILE_ATTRIBUTE_SYSTEM&dwAttr) return 0; if(FILE_ATTRIBUTE_COMPRESSED&dwAttr) return 0; if(FILE_ATTRIBUTE_ENCRYPTED&dwAttr) return 0; } // open the file/folder HANDLE hFile = CreateFile(szFilePath, GENERIC_READ|GENERIC_WRITE,FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, NULL); if(hFile == INVALID_HANDLE_VALUE) return 1; //set date time BOOL bVal = SetFileTime(hFile,&ftCreated,&ftAccessed,&ftModified); if(!bVal) { char *szBuff = (char*)malloc(sizeof(char)*1024); LPVOID lpMsgBuf; int err = GetLastError(); FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER|FORMAT_MESSAGE_FROM_SYSTEM, NULL, err, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR) &lpMsgBuf, 0, NULL); sprintf(szBuff,"Unable to set date to \n %s \n\nReason:%s \nError No:%d", szFilePath,lpMsgBuf,err), MessageBox(NULL,(LPTSTR)lpMsgBuf, "GetLastError", MB_OK|MB_ICONERROR); LocalFree(lpMsgBuf); } // close the handle CloseHandle(hFile); // if it is ignore then it should be set back to its original attribute if(g_bIgnoreAttrAndApply) SetFileAttributes(szFilePath,dwAttr); if(!bVal) return 2; return 0; } // it is a recursive function will // go through the files and folders within any folder int SetDateTimeToFolderFiles(HANDLE hSearchedFile, char *szPathName, FILETIME ftCreated, FILETIME ftModified, FILETIME ftAccessed) { WIN32_FIND_DATA stFindData; char *szCurFilename = (char*)malloc(sizeof(char)*_MAX_PATH); char *szCurPathname = (char*)malloc(sizeof(char)*_MAX_PATH); strcpy(szCurFilename,szPathName); strcpy(szCurPathname,szPathName); if((hSearchedFile == NULL)||(hSearchedFile ==INVALID_HANDLE_VALUE)) {// start the search sprintf(szCurFilename,"%s\\*.*",szPathName); hSearchedFile = FindFirstFile(szCurFilename,&stFindData); if(hSearchedFile == INVALID_HANDLE_VALUE) return 0; } else { if(!FindNextFile(hSearchedFile,&stFindData)) {// if no more file exists close it FindClose(hSearchedFile); return 0; } } strcat(szCurPathname,"\\"); strcat(szCurPathname,stFindData.cFileName); if(stFindData.dwFileAttributes&FILE_ATTRIBUTE_DIRECTORY) {// if it is a folder then .... if((!stricmp(stFindData.cFileName,"."))|| (!stricmp(stFindData.cFileName,".."))|| (!stricmp(stFindData.cFileName,""))|| (!stricmp(stFindData.cFileName,""))) { // call it recursively return SetDateTimeToFolderFiles(hSearchedFile, szPathName, ftCreated, ftModified, ftAccessed); } // call the set function for the found folder SetFileDateTime(szCurPathname, ftCreated, ftModified, ftAccessed); // call it recursively SetDateTimeToFolderFiles( NULL, szCurPathname, ftCreated, ftModified, ftAccessed); } // control will come here only if the found one is a file // set the date time to the file SetFileDateTime(szCurPathname, ftCreated, ftModified, ftAccessed); // call it recursively return SetDateTimeToFolderFiles(hSearchedFile, szPathName, ftCreated, ftModified, ftAccessed); }
Special attributed files cannot be set with new date & time. It should be reset to FILE_ATTRIBUTE_NORMAL to set new date and time. If the user doesn't check the checkbox Also apply to files with special attributes, then these special attributed files will be ignored while processing. This brings a new feature to this tool. User can ignore the special system files when mass data & time setting is done.
When you click Refresh, the selected folder or file's date & time will be retrieved and populated. The following code will do that...
// refresh will get date and time from folder/file and // CdateTimeCtrl will be populated with it void CFileDateDlg::OnBtnRefresh() { CString cszPath; m_edtPath.GetWindowText(cszPath); FILETIME ftCreated, ftModified, ftAccessed; BOOL bRet = GetFileDateTime(cszPath.GetBuffer(0), ftCreated, ftModified, ftAccessed); cszPath.ReleaseBuffer(); ((CDateTimeCtrl*)GetDlgItem(IDC_DATECREATED))->SetTime(ftCreated); ((CDateTimeCtrl*)GetDlgItem(IDC_DATEMODIFIED))->SetTime(ftModified); ((CDateTimeCtrl*)GetDlgItem(IDC_DATEACCESSED))->SetTime(ftAccessed); ((CDateTimeCtrl*)GetDlgItem(IDC_TIMECREATED))->SetTime(ftCreated); ((CDateTimeCtrl*)GetDlgItem(IDC_TIMEMODIFIED))->SetTime(ftModified); ((CDateTimeCtrl*)GetDlgItem(IDC_TIMEACCESSED))->SetTime(ftAccessed); }
Hope you will find this very useful. You are always welcome to modify this tool. I also want to remind you that I'm not responsible for any damage caused by this tool. Thanks.
