我可以创建一个与提交按钮一样工作的 CommandLink 吗?

问题描述：

请理解我缺乏写作技巧.

Please understand my lack of writing skills.

我正在测试以制作自定义凭据提供程序.我想创建一个 CommandLink 与提交按钮做同样的事情.我想通过 CommandLink 与提交按钮分开登录.目前，只有自定义凭据提供程序通过 providerFilter::Filter(CREDENTIAL_PROVIDER_USAGE_SCENARIO cpu, DWORD dwFlags, GUID* rgclsidProviders, BOOL* rgbAllow, DWORD cProviders) 公开.点击【anathor longon button】登录.

I am testing to make a custom credential provider. I want to create a CommandLink that does the same thing with the submit button. I want to log on through the CommandLink separately from the Submit button. Currently, only the custom credential provider is exposed through the providerFilter::Filter(CREDENTIAL_PROVIDER_USAGE_SCENARIO cpus, DWORD dwFlags, GUID* rgclsidProviders, BOOL* rgbAllow, DWORD cProviders). Click [anathor longon button] to log on.

这是我的示例代码:

 HRESULT CSampleCredential::CommandLinkClicked(DWORD dwFieldID)
 {
     HRESULT hr = S_OK;
     DWORD dwResult = 0;

     if (dwFieldID < ARRAYSIZE(_rgCredProvFieldDescriptors) &&
         (CPFT_COMMAND_LINK == _rgCredProvFieldDescriptors[dwFieldID].cpft))
     {
         HWND hwndOwner = nullptr;
         switch (dwFieldID)
         {
         case SFI_ANATHOR_SUBMIT_LINK:
             dwResult = function_foo();
             if(dwResult == 1) { 
                  Call GetSerialization()...?
                  Run the logon.
             }
             break;
             // ...
         }
     }
 }

因为您正在编写凭证提供程序，所以您已经在实现 ICredentialProvider 接口及其 Advise 方法:

Because you are writing credential provider, than you are already implementing ICredentialProvider interface and its Advise method:

    virtual HRESULT STDMETHODCALLTYPE Advise( 
        /* [annotation][in] */ 
        _In_  ICredentialProviderEvents *pcpe,
        /* [annotation][in] */ 
        _In_  UINT_PTR upAdviseContext) = 0;

第一个参数是指向事件接口 ICredentialProviderEvents 的指针，它只有一个方法:CredentialsChanged.您的任务是从用户(登录名/密码)那里获取凭据，将它们存储在您的内部并调用此方法.在下一个回合，您的提供者将被称为此方法:

The first argument is pointer to events interface ICredentialProviderEvents which have only one method: CredentialsChanged. Your task is to grab credentials from user (login/password) store them inside your internals and call this method. On the next turn your provider will be called this method:

    virtual HRESULT STDMETHODCALLTYPE GetCredentialCount( 
        /* [annotation][out] */ 
        _Out_  DWORD *pdwCount,
        /* [annotation][out] */ 
        _Out_  DWORD *pdwDefault,
        /* [annotation][out] */ 
        _Out_  BOOL *pbAutoLogonWithDefault) = 0;

您的任务是在 pdwDefault 和 pbAutoLogonWithDefault 参数中返回正确的值(我的建议是 0 和 TRUE).比实现 ICredentialProviderCredential 接口的类将立即为 GetSerialization 方法调用.

Your task is to return the correct values in pdwDefault and pbAutoLogonWithDefault parameters (my suggest is 0 and TRUE). Than your class that implementing ICredentialProviderCredential interface will be immediately called for GetSerialization method.

您可以在此处返回已存储的凭据.

Here you can return already stored credentials.
