获取DLL的函数和返回值 [英] Get function and return value of a DLL

问题描述

我正在尝试为VB.NET制作win32 api列表。我开始获取程序的参数，并通过其前缀（例如，ByVal dwThing As Long - > ByVal dwThing As UInteger）翻译成VB.NET。此时，一切都好（或多或少）。当我必须得到函数的返回值时，问题出现了（我的项目基于VB6 API声明，而且这种语言不能识别无符号类型，我在文件中看不到float或double）。然后我想得到函数名称和一些dll的返回值（如果可以更好地使用过程参数，因为我看到了那些的真正价值）。例如，



BOOL Beep（DWORD dwFreq，DWORD dwDuration）; （从MSDN中提取，这可以通过kernel32.dll库获得）



这可以做到吗？



提前致谢。



我的尝试：



我尝试过使用dumpbin.exe，但它没有得到（或者我不知道怎么做）返回值。我只希望函数（带参数和返回值）或subs（带参数）来比较结果并将它们设置为列表。

I'm trying to make a win32 api list for VB.NET. I started getting the parameters of the procedures, and by its prefixes (for example, ByVal dwThing As Long -> ByVal dwThing As UInteger) translated into VB.NET. At this point, all Ok (more or less). The problem comes when I have to get the return value of the functions (I'm basing my project in VB6 API declarations, and this language doesn't recognize unsigned types and I can't see a float or double in the file). Then I want to get the function name and return value of some dlls (if could be with the procedure parameters better, because I see the real value for those). For example,

BOOL Beep(DWORD dwFreq, DWORD dwDuration); (extracted from MSDN, this could be got with the kernel32.dll library)

This could be done?

Thanks in advance.

What I have tried:

I have tried with dumpbin.exe, but it doesn't get (or I don't know how to do it) the return values. I only want the functions (with parameters and return value) or subs (with parameters) to compare results and set them to the list.

推荐答案

VB6上个世纪已停产。切换到VB.NET，然后您可以使用如何：使用PInvoke从托管代码调用本机DLL Microsoft Docs [ ^ ]，已完成所有工作。

VB6 was discontinued last century. Switch to VB.NET and you can then use How to: Call Native DLLs from Managed Code Using PInvoke | Microsoft Docs[^], which has done all the work for you.
