Некорректное получение имен файлов с FTP

#39758189

Гость

Хочу получить имена всех файлов с FTP. Когда запускаю код на Windows 7 x32 Excel 2010, то все работает корректно, как только запускаю Windows 10 x64 Excel 2016, то получаю имя файла без первых 4 символов. Например на ftp файл физкультура.txt, на Windows 7 x32 Excel 2010 - результат "физкультура.txt", на Windows 10 x64 Excel 2016 -результат "ультура.txt". В чем может быть дело, подскажите.

Код: vbnet

м.б. InstrB, InstrW следует применять (т.к. разрядность систем различная, то и соотношение симоволов:байт будет другое)?

ldfanate,

Вам в принципе стоит добавить еще условного компилирования для 32/64 битности, в идеале получится 4 случая.

На 64 разрядной системе при поэтапном просмотре выполнения кода, я вижу, что имя файла я получаю после выполнения кода

Код: vbnet

ret = FtpFindFirstFile(hConn, remoteMatchFiles, fileFind, INTERNET_FLAG_RELOAD Or INTERNET_FLAG_NO_CACHE_WRITE, 0)

но почему не полное имя, не понятно.

ldfanateм.б. InstrB, InstrW следует применять (т.к. разрядность систем различная, то и соотношение симоволов:байт будет другое)?

Можете подсказать, где именно на моем примере можно использовать данные операторы. Честно, про InstrW вообще не нашел информации.

iMrTidyldfanate,

Вам в принципе стоит добавить еще условного компилирования для 32/64 битности, в идеале получится 4 случая.

А можно поподробнее или ссылку?

Если у кого-то есть еще какие-то варианты решения проблемы, напишите пожалуйста.

ещё м.б. потому что из API-структуры в Private Function TrimNulls(buffer As String) строку передаёте не как ByVal (т.е. lpstr) а как ByRef, т.е. в формате bstr - там какраз первые 4 байта в 64-битных должен занять счётчик количества символов в строке, вот его наверное и отрезает, т.к. процедура не понимает, что ей на вход строка без счётчика передаётся из API.

Некорректное получение имен файлов с FTP

#39759616

Bobax012

Гость

ldfanateещё м.б. потому что из API-структуры в Private Function TrimNulls(buffer As String) строку передаёте не как ByVal (т.е. lpstr) а как ByRef, т.е. в формате bstr - там какраз первые 4 байта в 64-битных должен занять счётчик количества символов в строке, вот его наверное и отрезает, т.к. процедура не понимает, что ей на вход строка без счётчика передаётся из API.

А как-то это можно подправить в коде?

Bobax012, для 64-битного варианта просто откусите 4 недостающих байта из структуры, например, за счет dwReserved1.
И везде вместо #If VBA7 нужно #If Win64
