Hi Experts
我正在开发一个ActiveX Edit Box控件，该控件已成功开发，并将其安装在64位计算机上，并且运行成功
但是问题是，在此文本框中输入的内容不能超过其边框长度.基本上是在ActiveX的TextBox边框之前键入有限的文本.

推荐答案

如果您用编辑框对Activex控件进行了子分类，请在COleControl派生类中更改PreCreateWindow函数，如下所示，

If you have sub classed the Activex control with edit box, change PreCreateWindow function as follows in COleControl derived class,

BOOL CEditActiveXCtrl::PreCreateWindow(CREATESTRUCT& cs)
{
    cs.style = cs.style | ES_AUTOHSCROLL | ES_AUTOVSCROLL | ES_MULTILINE; //for both horizontal and verical movement
    cs.lpszClass = _T("EDIT");
    return COleControl::PreCreateWindow(cs);
}
