Question

我有一个自定义控件，我试图在其中实现此网站上显示的网格控件https://www.codeproject.com/Articles/8/MFC-Grid-control。 https://social.msdn.microsoft.com/Forums/vstudio/en-US/035a3e74-596d-4534-8543-2e6ee545d582/how-to-use-grid-control-in-mfc

我实现了以下代码

// MFCApplication6Dlg.cpp：实现文件 //

import { flatMap } from 'rxjs/operators';
import { throwError } from 'rxjs';

...

saveExtrudedHeight(extrudedHeight): Observable<any> {
  const requestPayload = {
    extrudedHeight
  };
  return this.authService.onTokenChange()
    .pipe(flatMap(
    (token: NbAuthJWTToken) => {
      if (token.isValid()) {
        this.user = token.getPayload().user;
        this.payload = token.getPayload();

        const email = this.payload.user['email'];
        requestPayload.email = email;

        // Make the changes here to send the email as the Request Payload.

        return this.http.post('/extrudedHeight/save', requestPayload, httpOptions)
          .pipe(
            catchError(this.handleError)
          );
      } else {
        throwError('Something went wrong!');
      }
    }
  ));
}

任何帮助将不胜感激。

我没有将自定义控件的类添加为MFCGridCtrl。完成后，效果很好。

错误：如果您在对话框上使用MFC控件，则无法#define _AFX_NO_MFC_CONTROLS_IN_DIALOGS
