指向VB中的指针 [英] Pointer to a Pointer in VB

问题描述

我在尝试在VB中设置代码时遇到问题，以处理API定义中的

参数被定义为指针指针的情况。 API定义的摘录是：

void **对象//指向接口指针的指针

Object

[out]指向接口指针变量的指针，接收指针

接口。

有没有人为VB语言解决了这个问题？


Dave

I''m having a problem trying to set up code in VB to handle the case where an
argument in an API definition is defined as a pointer to a pointer. An
excerpt from the API''s definition is:
void ** Object //Pointer to an interface pointer
Object
[out] Pointer to an interface pointer variable that receives a pointer for
an interface.
Has anyone solved this for the VB language?

推荐答案

戴夫，

你试过这个问题吗？大厅"在

microsoft.public.dotnet.framework.interop新闻组？


不幸的是我怀疑这个新闻组中的大多数常客都做得不够

互操作以提供很多帮助。


如果你没有它Adam Nathan的书.NET和COM - 完整

互操作性指南来自SAMS Press，为你提供你想知道的关于Interop然后一些的所有东西。


希望这有助于

Jay

Dave,
Have you tried asking this "down the hall" in the
microsoft.public.dotnet.framework.interop newsgroup?

Unfortunately I suspect most regulars in this newsgroup do not do enough
interop to offer much assistance.

If you don''t have it Adam Nathan''s book ".NET and COM - The Complete
Interoperability Guide" from SAMS Press, provides you will every thing you
ever wanted to know about Interop and then some.

Hope this helps
Jay

是的。我在Interop组以及此处交叉发布它。那里没有运气

。


我不确定使用API​​是否在Interop域中，因为它与COM无关。 br />

无论如何，谢谢你的兴趣。

Yes. I crossposted it in the Interop group as well as here. No luck there as
yet.

I''m not sure if using API''s is in the Interop domain as its not COM related.

Thanks for your interest anyway.

你有没有尝试过使用IntPtr？
