Header file contains the problem-CodePudding

1, I use the command control creation: TADOConnection, which should contain a header file?
2, if I am to the baidu to search similar problems, using appropriate keywords?
Thank you very much,

 # include & lt; ADODB. Hpp>

CodePudding user response:

Should be in own HELP find, can be found,
There is a simple way, if you don't know what a control should use header files, then you can drag the control to the form, the IDE will automatically help you put relevant header file, you look at many what header file

CodePudding user response:

Directly from the palette drag controls can
#include

Add controls to the form, the form will automatically add header files.
