将通用文本从EditBox控件转换为_bstr_t实体 [英] conversion of a generic text from a EditBox Control into a _bstr_t entity

问题描述

我面临一个奇怪的问题.我试图从EditBox控件中获取文本，然后尝试将该文本转换为_bstr_t实体.

我将代码用作_bstr_t bstrVariable = :: allocSysString(str);

当我这样做时，我只得到bstrVariable中的第一个字符.

请注意，str不是常量字符串(它包含一些用户可以编辑的类型化数据)，否则allocSysString()可以正常工作.

因此，对此有任何帮助将不胜感激. :)

Hi,

I am facing a strange problem. I am trying to get a text from a EditBox Control, and then trying to convert that text into a _bstr_t entity.

I am using the code as _bstr_t bstrVariable = ::allocSysString(str);

and when I m doing this, I am getting only the first character in the bstrVariable.

Please note that str is not a constant string(it contains some typed data which user can edit), otherwise allocSysString() would have worked fine.

so any help on this would be appreciated. :)

推荐答案

CString str = "The string";

_bstr_t bstrTest( str );

//or

_bstr_t bstrTest = _bstr_t( str );
