使用C++管道实现进程间的通信，ui是基于qt开发的。

#include "dialog.h" #include "ui_dialog.h" Dialog::Dialog(QWidget *parent) : QDialog(parent), ui(new Ui::Dialog) { ui->setupUi(this); hPipe=NULL; } Dialog::~Dialog() { delete ui; if(hPipe) CloseHandle(hPipe); } void Dialog::on_createPipeButton_clicked() { hPipe=CreateNamedPipe(TEXT("//./pipe/MyPipe"),PIPE_ACCESS_DUPLEX,0,1,0,0,1000,NULL); if(INVALID_HANDLE_VALUE==hPipe) { QMessageBox::information(this,"News","Create NamedPipe failed."); hPipe=NULL; return; } printf("Server is now running ......\n"); if (ConnectNamedPipe(hPipe, NULL) == 0) // 等待客户机的连接 { printf("ConnectNamedPipe failed!\n"); } else { printf("ConnectNamedPipe success!\n"); } } void Dialog::on_writePipeButton_clicked() { char buf[]="hello,world."; DWORD dwWrite; if(!WriteFile(hPipe,buf,strlen(buf)+1,&dwWrite,NULL)) { QMessageBox::information(this,"NEWS","write failed."); return; } } void Dialog::on_readPipeButton_clicked() { char buf[100]; DWORD dwRead; if(!ReadFile(hPipe,buf,100,&dwRead,NULL)) { QMessageBox::information(this,"NEWS","read data failed."); return; } ui->label->setText(buf); }
