VB 利用DDE进程间通信，5行代码搞定

Client

添加Command1，Text1及一个pictureBox（命名为picDDE）

代码如下：

Option Explicit Private Sub Command1_Click() picDDE.LinkTopic = "app2|yuanyuan" picDDE.LinkMode = 2 picDDE.LinkExecute Text1.Text End Sub@H_<a href="/tag/404/" target="_blank" class="keywords">404</a>_10@ </p> <p><strong>Server</strong> </p> <p><a href="/tag/tianjia/" target="_blank" class="keywords">添加</a>Text1，设置工程<a href="/tag/mingcheng/" target="_blank" class="keywords">名称</a>为app2，设置窗体的LinkMode<a href="/tag/shuxing/" target="_blank" class="keywords">属性</a>为1，LinkTopic为yuanyuan</p> <p><a href="/tag/daima/" target="_blank" class="keywords">代码</a>如下：</p> <p><textarea cols="50" rows="15" name="code" class="vb">Option Explicit Private Sub Form_LinkExecute(CmdStr As String,Cancel As Integer) Text1.Text = CmdStr Cancel = 0 End Sub@H_<a href="/tag/404/" target="_blank" class="keywords">404</a>_10@ </p> <p><strong>验证<a href="/tag/fangfa/" target="_blank" class="keywords">方法</a>：</strong> </p> <p>假设编译后client为client.exe，server端为server.exe。先双击运行server.ext，然后再打开client.exe，在client端的文本框里输入消息然后点按钮发送，这样server.exe那边就会<a href="/tag/xianshi/" target="_blank" class="keywords">显示</a>出自于客户端的信息。</p> <p><strong>整个工程下载地址：</strong> </p> <p><a href="javascript:void()" class="outlink" data="/link?url=http://download.csdn.net/source/1759069" rel="nofollow" target="_blank">http://download.csdn.net/source/1759069</a> </p></div> <div class="topcard-tags"></div> <ul class="list-group"> <li class="list-group-item"><a href="/vb/262571.html" title="VB+Access删除一条记录后及时更新问题">上一篇：VB+Access删除一条记录后及时更新问</a><a href="/vb/262569.html" title="vb使用picturebox画曲线图" class="text-muted pull-right">下一篇：vb使用picturebox画曲线图</a> </li> </ul> </div> </div> </div>  <div class="row row-sm"> <div class="col-sm-12 col-md-12 col-lg-12"> <div class="card"> <ins class="adsbygoogle" style="display:block" data-ad-format="autorelaxed" data-ad-client="ca-pub-4605373693034661" data-ad-slot="9144498553"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({});
