The "vs" -prefix we used before was confusing and could // unintentionally have been interpreted as "Vdf-GUIdance String". // // The used naming-convention is: // - a prefix of "vWin32_" for every external function declaration // - a prefix of the letter "v" for the full API name for the vdf-wrapper function. // // By using this we are guarding ourselves for conflicts with variable declarations // of DataAccess in the future. // Or at least almost as the letter "v" is now also synonym for variant (duh~!) // // mm-dd-yyyy Author Description // // vSHGetFolderPath added to retrieve the new shell folders // vGetWindowsDirectory // // vGetTempFileName // vGetTempPath // 11-17-2001 **WvA: Removed User Interface Error popups such as Error handling. // This is an absolute need for WebApp. We expect you to handle the // error in your application anyways. Changed this for: // vDeleteFile, vCopyFile, vMoveFile and vRenameFile // 03-02-2002 **WvA: vRemoveDirectory added // 03-11-2002 **WvA: The parameter lpdword in the external function declaration for // vWin32_SHBrowsForFolder can cause compiler errors. // It is renamed too avoid this. // 11-11-2002 **WvA: Codecleanup, vcSelectFile_Dialog is now cvSelectFile_Dialog, its // function vSelectedFileName is now just SelectedFileName // Removed the local keyword in the variable declarations // 10-17-2003 **WvA: Cleaned up function vSelect_File and added code to destroy the dynamically // created file-open dialog // 02-12-2004 **WvA: Allan Ankerstjeme pointed me into a bug for the vCreateTempFileInPath // in that it didn't exactly return the correct filename of the file created. // This has now been taken care of. // 02-19-2004 **WvA: Removed all API declarations from the package itself to improve readability // These declarations are now included from the vWin32fh header file. // 02-19-2004 **WvA: Changed the default way in which the standard file handling works // Before today one could always undo the operation, as of now you cannot as // the default was a silly one using unnecessary resources (mainly diskspace) // Since i don't really expect someone to use that feature it has been removed. // One can however restore to the old way of handling by simply calling the // vWin32fhCompatibilityMode procedure ONE time before accessing any of the // filehandling operations // 02-19-2004 **WvA: The functions ParseFolderName, ParseFileName and ParseFileExtenstion added // as well as the StringFromRightOfChar function. // 02-19-2004 **WvA: sfoFormatDisk function added which can use to format a floppydisk // DISABLED now as testing shows that it does not work as advertised... // 02-20-2004 **WvA: The function vDDE_Error_Handler didn't pass the errornumber on to the DDE_Error_To_String function // Moved the hardcoded strings from vDDE_Error_Handler to define declarations for easier translation later on. // 09-10-2004 **WvA: Added the ToAnsi function to the fileoperations method so that // extended characters are treated ok too. // Reported by Flemming from // 12-17-2004 **WvA: Changed vFilePathExists to be global, reported by Peter van Mil // 12-28-2004 **WvA: WebApp compatibility added by introducing compiler directives Use Case.mac #IFNDEF Is$WebApp Use File_Dlg.pkg // Contains OpenDialog class definition #ENDIF Use Seq_chnl.pkg Use windows Use Dferror Use Dll Use vWin32fh.h // Header file with WinAPI declarations #IFNDEF Is$WebApp // *WvA: 13-01-1999 Created // The Class cSelectFile_Dialog is created to support the function Select_File // This function opens the Windows standard file open dialog and returns the selected // file_name.
