pass a control name as a variable and then hide a control using that variable
问题
我正在编写一个函数，它将接收一个名为`showme`的变量，这个变量是一个（在这种情况下）`FlowLayoutPanel`的名称，并且我想使用这个变量来将特定的面板设为可见。
ps 我是C++的新手！
任何帮助将不胜感激。
以下代码未能工作
void JommSwitchPanels(FlowLayoutPanel^ showme)
{
//在这里处理隐藏菜单面板的代码
showme->Visible = true; // 在showme上显示错误
flowfleet1->Visible = false;
flowhr->Visible = false;
}
英文:
I'm building a function that will receive the name of a (in this case) FlowLayoutPanel as variable showme and I want to use this variable to set that particular panel visible.
ps I am new to c++ !
Any help would be greatly appreciated.
The following is not working
void JommSwitchPanels(FlowLayoutPanel^ showme)
{
//stuff here to hide the menu panels
showme.Visable = true;//the error is shown on showme
flowfleet1->Visible = false;
flowhr->Visible = false;
}

showme 是一个指向 FlowLayoutPanel 对象的句柄。在 c++/cli 中解引用一个对象句柄要使用箭头运算符 (->)。你还有一个属性名的拼写错误 (Visable/Visible)。
因此，你需要将：
showme.Visable = true;
改为：
//----vv--------------
showme->Visible = true;
英文:
showme is a handle to a FlowLayoutPanel object.
Dereferencing a handle to object in c++/cli is done using the arrow operator (->).
You also have a typo in the property name (Visable/Visible).
Therefore you need to change:
showme.Visable = true;
To:
//----vv--------------
showme->Visible = true;
