我目前正在开发一个visual c ++程序，我的第一个表单上有多个文本框，所有文本框都需要一个数字。这些是做什么的要求输入一个数字（具体费用的数额）。对于我的一些费用，他们需要多笔较小的费用来计算费用。为了实现这一点，我首先禁用了相应的文本框，并在每个禁用的文本框旁边都有一个按钮。当用户单击每个文本框旁边的按钮时，它会显示一个单独的表单（同时仍保持主窗体打开），提示用户输入在该表单上单击按钮时总计的所有较小费用。然后，一旦他们单击按钮以总计表单上的费用，就会出现一个返回按钮，当单击该按钮关闭表单并仅打开主费用表单时。我的困境是我需要发回特定费用的总计算值，将其放在主费用表格的相应文本框中，以及启用该文本框。我相信我的方法是将值返回到主费用表单，然后将其分配给文本框，但是我不太确定如果用户单击按钮返回主费用表单后如何启用文本框较小的弹出费用表格。任何提示或想法将不胜感激。
好奇心的旁注：我是否需要在主费用表上启用文本框以便将返回的值放入其中，然后在计算中使用该值，该计算涉及主费用表上的所有费用？ / p>

我发现了this帖子，这正是我需要做的，但我只是不知道在哪里放置代码。
答案 0 :(得分：0)
通常做的事情（参见像FileDialog这样的类型）是将一些公共属性放在模态表单类中（这里是MiscExpensesCalculateForm）并在调用ShowDialog之前简单地设置它们并读取他们之后）。
private: System::Void button5_Click(System::Object^ sender, System::EventArgs^ e) {
MiscExpensesCalculateForm^ mecf = gcnew MiscExpensesCalculateForm();
mecf->SomeInputData = blahblah;
DialogResult dr = mecf->ShowDialog();
if(dr == DialogResult.OK) {
textBoxResult->Text = mecf->MyResultData;
textBoxResult->Enabled = true;
}
}
