Mixing Delphi and C++You have a TStringList and <algorithm>. What can you do? Quite a lot, actually. Did you know that as of RAD Studio 10.1 Berlin, Delphi‘s inbuilt containers, such as TList, the Generics. Collections containers, all enumerable types, and arrays, can be used from C++ using standard algorithms, iterators, and range-based for loops? This blog post contains a Youtube video of the C...
转载自:https://www.cnblogs.com/xumenger/p/4319354.html1. 介绍Win32 API和Win32系统。还要讨论Win32系统的功能以及它与16位系统在功能上的几个主要区别。只是让对Win32系统有一个基本的了解。当已经基本了解Win32操作后,就可以在任何需要的时候使用Win32系统提供的高级功能了。2. Win32环境中有两种基本的对象类型:内核对象和GDI/用户对象。 内核对象是Win32系统原有的,包括事件、文件映射、文件、邮件槽、互...

Delphi调用C#写的webservice 用delphi的THTTPRIO控件调用了c#写的webservice。下面是我调试时遇到的一些问题:1:导入wsdl文件:file--new----other----webservice---WSDLimporter---输入wsdl地址:如下:http://127.0.0.1/ WebService/WebServiceCall.asmx?wsdl注意末尾的:‘?wsdl‘不能少。要不可能会说找不到。2:设置THTTPRIO控件的属性:把http:// 127.0.0.1 /WebService/WebServiceCall.asmx?wsdl赋给URL属性,而不是赋给wsd...
实现步骤:1、生成密钥文件用于给程序集强名称签名(必须)sn -k MyKey.snk 2、使用强名称签名的Key编译成类库Tester.DLLcsc /t:library /keyfile:MyKey.snk Tester.cs3、生成类型库 (此tlb文件提供给Delphi导入, 使用OLE方式调用此步可省略了)tlbexp Tester.dll /out:Tester.tlb 4、生成注册DLL的注册表文件regasm Tester.DLL /regfile:Tester.reg5、运行Tester.reg将上面四个步骤打包成一个BAT文件自动生成DLL, 在运行Delphi程序前请...

百度搜索在线美化SQL语句的网站,为了加快解析速度,这里已下载到本地。
然后delphi用webbrowse载入本地的网页,然后把sql传进去,美化后取出来。
效果如下图

varaintf:_Recordset;RecordsAffected:OleVariant;

ADOStoredProc1.Close;ADOStoredProc1.Open;aintf:=ADOStoredProc1.Recordset;ADOQuery1.Recordset:=aintf;aintf:=aintf.NextRecordset(RecordsAffected);ADOQuery2.Recordset:=aintf;
end;
此时,把存储过程中生成的二个数据集分别在adoquery1,adoquery2中,将adoquery1,adoquery2与DBGrid相连中,即可.
其实,把_Recordset放到MemTable中更好.
下面是普遍的方法:

我正在从C#的dll中调用一个delphi函数.这是delphi函数签名-function CALinkDecode(sCode: PWideChar; SubscriberID, MailshotID, LinkID: PDWORD):PAnsiChar; stdcall;这就是我所说的.string input = "qvoxyetvr7wksss2zbrmr";int cas, cam, cal;var errorString = CALinkDecode(input, out cas,out cam, out cal);但是当我运行该应用程序时,它在delphi函数中将这种情况评估为true-if (sCode = nil) or (Length(sCode) <> 21) or (...
