每当我单击编辑控件，组合框区域对话框就会关闭.

如何在对话框和组合框中打印初始值?

When ever I click on edit control and combo box area dialog box get close.

How to print initial value in the dialog box and combo box?
and how to get values after clicking on OK button.

推荐答案

在此之后
开关(LOWORD(wParam))
{
案例IDOK:
GetDlgItemText(hAddRuleDlg，IDC_EDIT1，ipLocAddr，40);

案例IDCLOSE:
EndDialog(hAddRuleDlg，0);
返回TRUE;
}

我插入返回TRUE;现在工作正常.

After this
switch (LOWORD (wParam))
{
case IDOK :
GetDlgItemText(hAddRuleDlg,IDC_EDIT1,ipLocAddr,40);

case IDCLOSE :
EndDialog (hAddRuleDlg, 0);
return TRUE ;
}

i inserted return TRUE; and now it is working fine.
