我的窗口形式申请使用如下:
ofstream myfile;
myfile.open("foo.csv");
myfile << "whatever";
myfile.close()
档案产出在我计算机上被罚款,而同一目录中申请(编辑后自动取翻)。 然而,如果我把申请移至我的电脑上的另一地点,或者在使用窗户设置档案分发时,再上目标计算机,我就能够拿到文件。 是否有任何人知道如何这样做?

它应当在任何计算机上进行罚款。
两种可能的原因:
(1) 出现错误,使档案无法书写,或
2) 在你预计会收到档案时,档案没有书写。
明确检查错误。 例如:
std::ofstream outFile("foo.csv");
if (!outFile)
{
// Open failed - take error handling action.
}
ADDENDUM: 这印有错误信息:
std::ofstream outFile("foo.csv");
if (!outFile)
{
// Open failed - take error handling action.
cout << "error reading file foo.csv" << " error: " << strerror(errno) << endl;
}
