％1不是有效的win32应用程序错误 [英] %1 is not a valid win32 application error

问题描述

我创建了64位exe和32位com ...我在某些网站建议的注册表中进行了必要的更改..



现在CoCreateInstance正在返回：



HRESULT_FROM_WIN32（ERROR_BAD_EXE_FORMAT）：％1不是有效的Win32应用程序。 HRESULT





能告诉我为什么上面提到的错误。



我尝试了什么：

I Created a 64 bit exe and 32 bit com dll ... i did neccesary changes in registry as suggested by some site ..

now CoCreateInstance is returning :

HRESULT_FROM_WIN32(ERROR_BAD_EXE_FORMAT) : %1 is not a valid Win32 application. HRESULT


Could you please let me know why the error came which is mentioned above.

What I have tried:

int _tmain(int argc, _TCHAR* argv[])
{
	ICMATHCAUCULATOR *pMathcalci = nullptr;
	HRESULT hr;
	CoInitialize(NULL);
	hr = CoCreateInstance(CLSID_CMATHCAUCULATOR, NULL, CLSCTX_LOCAL_SERVER, IID_ICMATHCAUCULATOR, (void**)&pMathcalci);


	if (SUCCEEDED(hr))
	{
		cout << "function is called" << endl;
		double drresult = 0.0;
		pMathcalci->SumofTowNumbers(10.0, 50.0, &drresult);
		cout << " value is " << drresult << endl;
	}

	CoUninitialize();
	return 0;
}

exe是64位dll是32位

exe is 64 bit dll is 32 bit

推荐答案

你是如何注册你的COM dll？

默认使用64位版本的RegSvr32，你需要使用32位版本。

见https://support.microsoft.com/en-us/kb/249873 [ ^ ]



这里有一般的信息：流程互操作性（Windows） [< a href =https://msdn.microsoft.com/en-us/library/windows/desktop/aa384231(v=vs.85).aspx\"target =_ blanktitle =New Window> ^ ]

How did you register your COM dll?
By default the 64-bit version of RegSvr32 is used and you need to use the 32-bit version.
See https://support.microsoft.com/en-us/kb/249873[^]

And here is some general information: Process Interoperability (Windows)[^]

除非我误解了文档，否则你不能这样做。请参阅流程互操作性（Windows） [ ^ ]：

在64位Windows上，64位进程无法加载32位动态链接库（DLL）。此外，32位进程无法加载64位DLL。

Unless I misunderstood the documentation, you cannot do that. See Process Interoperability (Windows)[^]:
On 64-bit Windows, a 64-bit process cannot load a 32-bit dynamic-link library (DLL). Additionally, a 32-bit process cannot load a 64-bit DLL.
