问题描述

我的目的是将win32应用程序更改为win32 libray，并使用c＃应用程序调用win32 libray。

但是会出现一些问题。



win32应用程序的问题写如下：

my purpose is to change win32 application to win32 libray,and use c# application to invoke win32 libray.
but there some questions that occurs.

the win32 application's problem write as below:

int WINAPI WinMain(HINSTANCE	hInstance,			// current form instance
	           HINSTANCE	hPrevInstance,		// pre form instance
		   LPSTR		lpCmdLine,			// parameters command
		   int			nCmdShow)			// show the form states
{
    step 1: create main form use api function.
    step 2: create while to catch windows message
            
    while(!done)									
    {
		if (PeekMessage(&msg,NULL,0,0,PM_REMOVE))	// is there have message to wait?
		{
			if (msg.message==WM_QUIT)				
				done=TRUE;			// yes, receive the quit message
			else									// no
			{
				TranslateMessage(&msg);				
				DispatchMessage(&msg);				
			}
		}
     }
}







LRESULT CALLBACK WndProc(HWND	hWnd,			// current form's instance
			 UINT	uMsg,			// windows message
			 WPARAM	wParam,			
			LPARAM	lParam)			
{

        switch (uMsg)	//check message							
	{
              if(LOWORD(wParam)==1001)
	      {
				CreateDialog(hInstanceTemp, MAKEINTRESOURCE(IDD_2001), hWnd, (DLGPROC)MainuDlgProc1);
				EnableWindow(GetDlgItem(hWnd,1001),FALSE);
	       }
         }
}

{
	switch(u_Msg)
	{
		case WM_INITDIALOG:

我的问题是：

如果我将win32应用程序更改为库，并使用c＃form调用libray。

first：删除步骤1，然后删除步骤2，即删除win32表单。

秒：将csharp.h添加到win32，并定义如下函数：





my question is:
if i change the win32 application to library,and use c# form to invoke libray.
first: remove the step 1,and remove the step 2,that is remove the win32 form.
second:add csharp.h to win32,and define function as below:

extern "C" DLL_API  void ParaSetting(HWND _hwnd);
void ParaSetting(HWND _hwnd)
{
	CreateDialog(hInstance, MAKEINTRESOURCE(IDD_2001), _hwnd, (DLGPROC)MainuDlgProc1);
}





所以我可以使用dllimport来调用win32 ParaSetting函数。

但是问题是：当我调用ParaSetting函数时，它无法创建对话框表单，因为win32库不包含while循环发送消息。

我怎样才能解决这个问题并实现相同的功能作为win32应用程序？



so i can use dllimport to invoke the win32 ParaSetting function.
but the question is : when i invoke ParaSetting function,it can't create the dialog form, because the win32 library not contains the while loop to send message.
how can i solve this quesion and achive the same function as win32 application?

推荐答案

我必须让理查德和谢尔盖认为你的代码非常不清楚且难以理解。最好用C＃重写所有内容。它使调试更容易。



对于C ++和C＃之间的交互，您可以查看我的文章呼叫所有电台和附加的代码。
I must commit Richard and Sergey that your code is very unclear and hard to understand. And it would better to rewrite all in C#. It makes also debugging easier.

For interaction between C++ and C# you can take a look on my article Calling All Stations and the attached code.
