Question

我继承了一个嵌入在会计科目表中的宏。在32位机器上使用时效果很好。 64位计算机正在慢慢推出，用户在64位计算机上遇到问题。用户按下搜索按钮以显示弹出窗口。他们输入帐号并按＆＃34;查找＆＃34;按钮，它将它们带到他们输入的第一个实例。如果他们推动＆＃34;发现＆＃34;再次，它将他们带到第二个实例，依此类推。

我知道我必须进入＆＃34; ptrsafe＆＃34;在每个声明中，我已经这样做了。但是，我们现在在MsgBoxEx函数上遇到类型不匹配错误。＆＃34; AddressOf zWindowProc＆＃34;在此功能中突出显示。

任何人都可以帮忙解决需要改变的问题吗？谢谢你的帮助.........

我能够解决我的问题。我在这个forumn的另一个问题中找到了这个链接，这是一个很大的帮助。我一行一行地为每个声明语句添加了64位版本，我还必须将几个变量更改为64位版本，它现在可以在32位或64位机器上运行。
