好的,我可以帮您写一个使用wxWidgets界面库的tcp协议传输文件的程序。以下是简单的代码示例:
首先,您需要包含必要的头文件:
```cpp
#include <wx/wx.h>
#include <wx/socket.h>
#include <wx/protocol/tcp.h>
```
然后,在您的类中定义以下成员变量:
```cpp
wxSocketClient* m_Client;
wxProgressDialog* m_ProgressDialog;
```
接着,您需要编写连接到服务器的函数:
```cpp
void Connect()
{
m_Client = new wxSocketClient(wxSOCKET_NOWAIT);
// IP and Port of the server
wxIPV4address addr;
addr.Hostname("localhost");
addr.Service(12345);
if (m_Client->Connect(addr))
{
// Connection successful
// You can now send/receive data over the socket
}
else
{
// Connection failed
}
}
```
下一步是发送文件。在此例中,我们将发送名为“test.txt”的文件:
```cpp
void SendFile()
{
wxFileInputStream file("test.txt");
wxTCPSocketOutputStream str(m_Client);
m_Client->Notify(true); // Enable events
const size_t bufferSize = 1024;
char buffer[bufferSize];
size_t totalBytesSent = 0;
wxFileOffset fileSize = file.GetSize();
while (!file.Eof())
{
size_t bytesRead = file.Read(buffer, bufferSize);
size_t bytesSent = 0;
while (bytesSent < bytesRead)
{
int result = str.Write(buffer + bytesSent, bytesRead - bytesSent);
if (result < 0)
{
// Error
return;
}
bytesSent += result;
totalBytesSent += result;
}
// Show a progress dialog
int percentComplete = (int)(totalBytesSent * 100 / fileSize);
m_ProgressDialog->Update(percentComplete);
}
// File transfer complete
}
```
最后,您需要创建一个类似的函数以接收文件。
希望对您有所帮助!
