如何在.NET中获得主要的forM句柄 [英] How to get the main forM handle in .NET

问题描述

我正在尝试使用需要主窗口句柄的第三方DLL作为

参数。


例如MyFunc（WHND MyHandle）;


示例如下所示：


结果= MyFunc（句柄）;


其中处理是Win32句柄。


尝试使用编写的示例导致编译器错误：

无法将参数5从''int''转换为' 'HWND''


首先，HWND基本上不是无符号整数吗？我尝试过类型

施放和其他一些东西，但编译器没什么好看的。


有谁知道如何使这个工作？

I am trying to use a 3rd party DLL that requires the main window handle as
a parameter.

e.g. MyFunc(WHND MyHandle);

The example looks something like this:

Result = MyFunc(Handle);

Where "Handle" is the Win32 handle.

Trying to use the example as written results in a compiler error:
cannot convert parameter 5 from ''int'' to ''HWND''

First isn''t the HWND basically an unsigned integer? I have tried type
casting and several other things, but nothing the compiler likes.

Does anyone know how to make this work?

MyFunc（WHND MyHandle）;


错字？你的意思是这个？


MyFunc（HWND MyHandle）;


这个例子看起来像这样：

结果= MyFunc（Handle）;

其中Handle是Win32句柄。

无法将参数5从''int''转换为''HWND''


首先，完全按照书面形式发布代码总是一个好主意;魔鬼

在细节中。


这是一个猜测：如果你必须，施放第五个参数：


更改...（... x，...）;


到


...（... （HWND）x，...）;

首先，HWND基本上不是无符号整数吗？


使用Von Neumann机器，一切基本上都是整数。那么，什么？

:-)

我尝试过类型转换和其他一些事情，
但编译器不喜欢。

Typo? You mean this?

MyFunc(HWND MyHandle);

The example looks something like this:

Result = MyFunc(Handle);

Where "Handle" is the Win32 handle.

Trying to use the example as written results in a compiler error:
cannot convert parameter 5 from ''int'' to ''HWND''
First, it is always a good idea to post code exactly as written; the devil
is in the details.

This is a guess: If you must, cast the 5th parameter:

change ...(... x, ...);

to

...(... (HWND) x, ...);
First isn''t the HWND basically an unsigned integer?
Using Von Neumann machines, everything is basically an integer. So, what?

正如我所说，显示错误的代码，错误消息的确切文本以及您尝试过的

。

As I said, show the bad code, the exact text of the error message and what
you have tried.

对于错字感到抱歉，只是想简化。


它来自不同的地方，但这里是实际的代码：


typedef int（_stdcall * pOmniConnect）（char * IpAddress，

unsigned int端口，

unsigned int超时，

unsigned char EncryptionKey [16]，

HWND NotifyWindow）;

。 ...

pOmniConnect OmniConnect;

....

加载dll并解决地址（与问题无关）

....

OmniConnect（IpEdit->文字，

PortEdit->文字 - > ToInt32，

TimeoutEdit-> Text-> ToInt32，

BinKey，

句柄）; //这行是问题

如写：

错误C2664：''int（... func template ...）''：无法转换参数5

从''int''到''HWND''


尝试类型转换例如（HWND）句柄）;

错误C2440" ''type cast''：无法从''System :: IntPtr''转换为''HWND''


尝试了各种各样的 - > Handle和Handle-> xxx转换但类似的问题

问题。

Sorry about the typo, was just trying to simplify.

It''s pulled from various places, but here is the actual code:

typedef int (_stdcall *pOmniConnect) (char * IpAddress,
unsigned int Port,
unsigned int Timeout,
unsigned char EncryptionKey[16],
HWND NotifyWindow);
....
pOmniConnect OmniConnect;
....
The dll is loaded and addresses resolved (not relevant to problem)
....
OmniConnect(IpEdit->Text,
PortEdit->Text->ToInt32,
TimeoutEdit->Text->ToInt32,
BinKey,
Handle); // this line is the problem
As Written:
error C2664: ''int(... the func template ...)'': cannot convert parameter 5
from ''int'' to ''HWND''

Tried type casting e.g. (HWND)Handle);
error C2440" ''type cast'' : cannot convert from ''System::IntPtr'' to ''HWND''

Tried various this->Handle, and Handle->xxx conversions but similar
problems.

如何宣布Handle？
