如何在C ++中创建外壳程序使用的IconHandler? [英] How to create a IconHandler used by the shell in c++?
问题描述
我试图用C ++编写一个图标处理程序，但是这样做有一些问题.我从 codeproject
I tried to code an icon handler in c++ but i have some issues to do this. I followed the turoriel from codeproject
本教程的不同之处在于，我想使用Visual Studio向导(2013)的ATL项目对dll进行编码.因此，我创建了一个新的ATL项目，并且对该项目有一个COM +1类(即标头的代码).
The difference with this tutorial is i wanna code my dll with an ATL project from the wizard of visual studio (2013). So i create a new ATL project and i had a COM +1 class to this project (this the code of the header).
问题是它接缝了我的dll，但之后又分离了.
The problem is it seams that my dll is attach but is detach right after.
我将在下面放一些代码和更多的说明:
I'll put some code and more explication bellow :
extern "C" BOOL WINAPI DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
if (dwReason == DLL_PROCESS_ATTACH)
{
_AtlModule.InitLibId();
//_AtlModule.RegisterAppId();
}
return _AtlModule.DllMain(dwReason, lpReserved);;
}
这是我dll的入口点.我对此入口点做了很多尝试和测试.我试图写一些dwReason的登录功能，并且该功能仅在编译时才启动.一次使用属性DLL_PROCESS_ATTACH，另一次使用属性DLL_PROCESS_DETACH.之后，即使我将注册表设置为在文件的IconHandler中调用此dll，也无法进行任何工作.
This is my entry point of my dll. I did a lot of try and test on this entry point. I tried to write some log in function of the dwReason and this function is launch only when i compile. One time with the attribute DLL_PROCESS_ATTACH and an other time with the attribute DLL_PROCESS_DETACH. After that nothing seams to work even when i set my registry to call this dll in the IconHandler of my file.
我将放置dllmain.h，handler.h，idl文件和rgs文件.如果您需要更多代码来帮助我，我会在以后放它们.
I'll put my dllmain.h, my handler.h, my idl file and my rgs file. If you need more code to help me i'll put them later.

在dllmain上查看我的测试. cpp
See my test on my dllmain. cpp
BOOL ret = false;
FILE *file;
fopen_s(&file, "test.txt","a+"); /* apend file (add text to
a file or create a file if it does not exist.*/
if (dwReason == DLL_PROCESS_ATTACH)
{
fprintf(file,"%s","Initialize AtlModule\n"); /*writes*/
_AtlModule.InitLibId();
HRESULT hr = _AtlModule.RegisterAppId();
if (SUCCEEDED(hr))
{
fprintf(file,"%s","Registrer app succeeded \n"); /*writes*/
hr = _AtlModule.RegisterServer(TRUE, &CLSID_QIHandler);
if (SUCCEEDED(hr))
{
fprintf(file,"%s","RegisterServer succeeded \n"); /*writes*/
hr = _AtlModule.UpdateRegistryAppId(TRUE);
if (SUCCEEDED(hr))
{
fprintf(file,"%s","UpdateRegistryAppId succeeded \n"); /*writes*/
ret = true;
}
}
}
}
#ifdef _DEBUG
else if (dwReason == DLL_PROCESS_DETACH)
{
_AtlModule.UpdateRegistryAppId(FALSE);
_AtlModule.Term();
}//*/
#endif
if (dwReason == DLL_PROCESS_DETACH && lpReserved != NULL)
{
ret = true;
}
else if (dwReason == DLL_PROCESS_DETACH)
{
fprintf(file,"%s","Execption ! \n"); /*writes*/
}
fclose(file); /*done!*/
return ret;
test.txt中的结果:
The result in my test.txt :
Initialize AtlModule
Registrer app succeeded
RegisterServer succeeded
UpdateRegistryAppId succeeded
Execption !
这里的人有想法吗?
推荐答案
我没有找到可以解决我问题的解决方案.因此，即使这不是执行此操作的最佳方法，我也用C#编写了处理程序，因为这会调用某些本机函数.
I didn't found any solution to work my solution. So i write my handler in C# even if this is not the best way to do that because that call some native function.
我使用了来自代码项目的以下教程: NET-Shell-Extensions-Shell-Icon-Handlers
I used the follow tutorial from code-project : NET-Shell-Extensions-Shell-Icon-Handlers
我希望本教程能够对某些人有所帮助.如果有人对我的预览问题有答案，我将很高兴知道我该怎么做.
I hope this tutorial gonna help some people. If someone have the answer to my preview question i will be glad to know what i have to do.
