请问可不可用MFC调用写好的winform程序的dll

在我用mfc调用的winform程序dll的时候，会报没有spread。net license，有没有解决方法！

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：
http://www.gcpowertools.com.cn/products/Spcom_overview.htm

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：

1. Visual C++
   
2. using namespace System;
   
3. using namespace System::Reflection;
   
4. using namespace System::Security::Policy;
   
5. //for evidence object
   
6. using namespace System::Security;
   
7. //for securityzone object
   
8. using namespace System::Collections;
   
9. 
   
10. //for IEnumerator
    
11. int main()
    
12. {
    
13. 
    
14.    // Create appdomainsetup information for the new appdomain.
    
15.    AppDomainSetup^ domaininfo = gcnew AppDomainSetup;
    
16.    domaininfo->ApplicationBase = System::Environment::CurrentDirectory;
    
17.    domaininfo->ConfigurationFile = System::Environment::CurrentDirectory + "\\ADCreateDomain.exe.config";
    
18.    domaininfo->ApplicationName = "MyApplication";
    
19.    domaininfo->LicenseFile = System::Environment::CurrentDirectory + "\\license.txt";
    
20. 
    
21.    //Create evidence for new appdomain.
    
22.    Evidence^ adevidence = AppDomain::CurrentDomain->Evidence;
    
23. 
    
24.    //Add the zone and url information to restrict permissions assigned to the appdomain.
    
25.    adevidence->AddHost( gcnew Url( "http://www.example.com" ) );
    
26.    adevidence->AddHost( gcnew Zone( SecurityZone::Internet ) );
    
27. 
    
28.    // Create the application domain.
    
29.    AppDomain^ newDomain = AppDomain::CreateDomain( "MyDomain", adevidence, domaininfo );
    
30. 
    
31.    // Write out the application domain information.
    
32.    Console::WriteLine( "Host domain: {0}", AppDomain::CurrentDomain->FriendlyName );
    
33.    Console::WriteLine( "child domain: {0}", newDomain->FriendlyName );
    
34.    Console::WriteLine();
    
35.    Console::WriteLine( "Application base is: {0}", newDomain->SetupInformation->ApplicationBase );
    
36.    Console::WriteLine( "Configuration file is: {0}", newDomain->SetupInformation->ConfigurationFile );
    
37.    Console::WriteLine( "Application name is: {0}", newDomain->SetupInformation->ApplicationName );
    
38.    Console::WriteLine( "License file is: {0}", newDomain->SetupInformation->LicenseFile );
    
39.    IEnumerator^ newevidenceenum = newDomain->Evidence->GetEnumerator();
    
40.    while ( newevidenceenum->MoveNext() )
    
41.       Console::WriteLine( newevidenceenum->Current );
    
42. 
    
43.    AppDomain::Unload( newDomain );
    
44. }

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

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。
