delphi中使用shellexecute ( 积分: 100 )

调用exe应用程序,返回值5.<br>shellExecute(0,nil,PChar('F:/Client/App.exe',PChar(TransParams),nil,SW_SHOWNORMAL);<br>返回值为5,为什么?<br>如果,TransParams小一些的话就返回42.可以执行App.exe.<br>搞了两天了,真是晕死了.

用dos-command执行一下app.exe&nbsp;TransParams,看看是否有问题。

参数太长了啊,不好弄.<br>有没有更好的方式?

shellExecute(handle,nil,PChar('F:/Client/App.exe'),PChar(TransParams),nil,SW_SHOWNORMAL);试试！我试过调用一个VB做的Exe，传了9个参数过去没问题！

试试<br>shellExecute(0,nil,PChar('F:/Client/App.exe&nbsp;'&nbsp;+&nbsp;TransParams),nil,nil,SW_SHOWNORMAL);
