Error while compiling

[User 10909830]

error C2440: 'static_cast' : cannot convert from 'void (__thiscall COptionDBTransport::* )(PCTSTR)' to 'AFX_PMSG'

Throws error at this line-

ON_BN_CLICKED(IDC_BUTTON_udpCheck, &COptionDBTransport::OnBnClickedButtonudpcheck)

Please help me for this issue.

Seemingly your only problem is that your method signature doesn't match. See the AFX_PMSG[^] signature. You method receives a PCTSTR parameter while a button event handler should be a method without any parameters.

Does your COptionDBTransport inherit from CCmdTarget (or a derived type of it)? Have you included (even if indirectly) ? (ON_BN_CLICKED is defined in another header)

[User 10909830]

Thanks, Yes Have inculded the header file.

[User 10909830]

Yes ,it is inherited from CCmdTarget(base class of all classes used) M still stuck to that error @pasztorpisti-How to pass multiple parameters to a button event handler.

[pasztorpisti]

You can not pass a parameter to a button event handler. You have to gather the data in the handler - for example by querying textboxes/checkboxes/etc in your handler method.

[User 10909830]

thanks pasztorpisti, will try that.

Then I'm totally baffled. Recommend you compile with /P (preprocess to file) and then, from a command-prompt try to compile that generated file. It should contain #line directives and such making it (hopefully) obvious why it fails. ++luck;
