newdimchina 你好，

Spread .NET 6 基于 .NET 平台开发，我们推荐用户在 .NET 平台下使用。

在 C++ 中可以使用 Spread COM 版本，产品功能请浏览：

以上，
谢谢

这样啊，因为Spread COM支持的Excel公式等功能没有 .NET强大，我们才选择.NET的。
这样的话，是不是没有其他方法了。
谢谢回复~

newdimchina 你好，
我这里可以提供一种通用的方法你可以尝试。
在 C++ 中创建 AppDomainSetup 创建托管环境，通过AppDomainSetup 下 LicenseFile 属性去引用 license 文件。
可以根据链接中资源去实现在 C++ 中引用 license 文件：http://technet.microsoft.com/zh- ... .appdomain.evidence(VS.90).aspx
代码如下：

Visual C++
using namespace System;
using namespace System::Reflection;
using namespace System::Security::Policy;
//for evidence object
using namespace System::Security;
//for securityzone object
using namespace System::Collections;
//for IEnumerator
int main()
{
// Create appdomainsetup information for the new appdomain.
AppDomainSetup^ domaininfo = gcnew AppDomainSetup;
domaininfo->ApplicationBase = System::Environment::CurrentDirectory;
domaininfo->ConfigurationFile = System::Environment::CurrentDirectory + "\\ADCreateDomain.exe.config";
domaininfo->ApplicationName = "MyApplication";
domaininfo->LicenseFile = System::Environment::CurrentDirectory + "\\license.txt";
//Create evidence for new appdomain.
Evidence^ adevidence = AppDomain::CurrentDomain->Evidence;
//Add the zone and url information to restrict permissions assigned to the appdomain.
adevidence->AddHost( gcnew Url( "http://www.example.com" ) );
adevidence->AddHost( gcnew Zone( SecurityZone::Internet ) );
// Create the application domain.
AppDomain^ newDomain = AppDomain::CreateDomain( "MyDomain", adevidence, domaininfo );
// Write out the application domain information.
Console::WriteLine( "Host domain: {0}", AppDomain::CurrentDomain->FriendlyName );
Console::WriteLine( "child domain: {0}", newDomain->FriendlyName );
Console::WriteLine();
Console::WriteLine( "Application base is: {0}", newDomain->SetupInformation->ApplicationBase );
Console::WriteLine( "Configuration file is: {0}", newDomain->SetupInformation->ConfigurationFile );
Console::WriteLine( "Application name is: {0}", newDomain->SetupInformation->ApplicationName );
Console::WriteLine( "License file is: {0}", newDomain->SetupInformation->LicenseFile );
IEnumerator^ newevidenceenum = newDomain->Evidence->GetEnumerator();
while ( newevidenceenum->MoveNext() )
Console::WriteLine( newevidenceenum->Current );
AppDomain::Unload( newDomain );
}

ADCreateDomain.exe.config没有这个文件啊，
AppDomain^ newDomain = AppDomain::CreateDomain( "MyDomain", adevidence, domaininfo );我得到的newDomain 属性值倒是error的，我是再mfc中添加的

BOOL Ctest_for_csharp_dllApp::InitInstance()
{
// InitCommonControlsEx() is required on Windows XP if an application
// manifest specifies use of ComCtl32.dll version 6 or later to enable
// visual styles. Otherwise, any window creation will fail.
INITCOMMONCONTROLSEX InitCtrls;
InitCtrls.dwSize = sizeof(InitCtrls);
// Set this to include all the common control classes you want to use
// in your application.
InitCtrls.dwICC = ICC_WIN95_CLASSES;
InitCommonControlsEx(&InitCtrls);
CWinAppEx::InitInstance();
AfxEnableControlContainer();
// Standard initialization
// If you are not using these features and wish to reduce the size
// of your final executable, you should remove from the following
// the specific initialization routines you do not need
// Change the registry key under which our settings are stored
// TODO: You should modify this string to be something appropriate
// such as the name of your company or organization
SetRegistryKey(_T("Local AppWizard-Generated Applications"));
AppDomainSetup^ domaininfo = gcnew AppDomainSetup;
domaininfo->ApplicationBase = System::Environment::CurrentDirectory;
domaininfo->ConfigurationFile = System::Environment::CurrentDirectory + "\\ADCreateDomain.exe.config";
domaininfo->ApplicationName = "test_for_csharp_dll";
domaininfo->LicenseFile = System::Environment::CurrentDirectory + "\\licenses.txt";
//Create evidence for new appdomain.
Evidence^ baseEvidence = AppDomain::CurrentDomain->Evidence;
Evidence^ adevidence = gcnew Evidence( baseEvidence );
//Add the zone and url information to restrict permissions assigned to the appdomain.
adevidence->AddHost( gcnew Url( "http://www.example.com" ) );
adevidence->AddHost( gcnew Zone( SecurityZone::Internet ) );
// Create the application domain.
AppDomain^ newDomain = AppDomain::CreateDomain( "MyDomain", adevidence, domaininfo );
// Write out the application domain information.
Console::WriteLine( "Host domain: {0}", AppDomain::CurrentDomain->FriendlyName );
Console::WriteLine( "child domain: {0}", newDomain->FriendlyName );
Console::WriteLine();
Console::WriteLine( "Application base is: {0}", newDomain->SetupInformation->ApplicationBase );
Console::WriteLine( "Configuration file is: {0}", newDomain->SetupInformation->ConfigurationFile );
Console::WriteLine( "Application name is: {0}", newDomain->SetupInformation->ApplicationName );
Console::WriteLine( "License file is: {0}", newDomain->SetupInformation->LicenseFile );
IEnumerator^ newevidenceenum = newDomain->Evidence->GetEnumerator();
while ( newevidenceenum->MoveNext() )
Console::WriteLine( newevidenceenum->Current );
Ctest_for_csharp_dllDlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
// TODO: Place code here to handle when the dialog is
// dismissed with OK
}
else if (nResponse == IDCANCEL)
{
// TODO: Place code here to handle when the dialog is
// dismissed with Cancel
}
AppDomain::Unload( newDomain );
// Since the dialog has been closed, return FALSE so that we exit the
// application, rather than start the application's message pump.
return FALSE;
}

Spread .NET 版本没有在 MFC 环境下经过严格的测试，我们一般不推荐用户如此使用，
从提示看是程序集引用问题，可以在网上搜索一些参考资源。

嗯，已经决定不这样做的，非常感谢~

好的如果有其他问题欢迎继续交流。

在MFC App中使用 spread .net for winform 是可行的，我实际做过。
我也遇到过你这个license报错的问题。后来想办法绕过去了。
