拷贝文件时如何显示进度？有什么方法？

[xiaogq]

CopyFileEx

[HEROIN]

BOOL CopyFileEx(

LPCWSTR lpExistingFileName, // 源文件名

LPCWSTR lpNewFileName, //目标文件

LPPROGRESS_ROUTINE lpProgressRoutine, // 指向一个回调函数

LPVOID lpData, //传给回调函数的数据

LPBOOL pbCancel, // flag that can be used to cancel the operation
DWORD dwCopyFlags // flags that specify how the file is copied
);



The CopyProgressRoutine function is called when a portion of a copy operation started by CopyFileEx is completed. This function is an application-defined callback routine.

DWORD WINAPI CopyProgressRoutine(

LARGE_INTEGER TotalFileSize, // total file size, in bytes
LARGE_INTEGER TotalBytesTransferred, // total number of bytes transferred
LARGE_INTEGER StreamSize, // total number of bytes for this stream
LARGE_INTEGER StreamBytesTransferred, // total number of bytes transferred for this stream
DWORD dwStreamNumber, // the current stream
DWORD dwCallbackReason, // reason for callback
HANDLE hSourceFile, // handle to the source file
HANDLE hDestinationFile, // handle to the destination file
LPVOID lpData // passed by CopyFileEx
);

这个函数不能在win95下面用呀

[BCB]

为了考虑win95也能用,就只好自已编个MyCopyFile(char *s,char *d)
一边复制一边向进度条中送进度值(大约值),这个子程序很简单

Good luck to you

试试！回头再来。

可以加入一个Progressbar控件，然后再把拷贝事件和它关联起来

[kimryo]

复制文件新建一个线程，在主线程中用Timer取得已复制的大小就行了。

当然，如果自定义消息，在复制线程向主线程发消息更好。

我的方法是结合fopen,fwrite写了一个拷贝函数,在fwrite的时候进行进度显示.
