Problems Occurred When printing the dialog box Program

In the print program Program program of the dialog box, if the class inherited from the cpreviewview () class is not added and the toolbar for custom print preview is not added, when printing or previewing, an error similar to the following occurs:

Debug assertion failed!

Program:

C: \ Users \ [user_name] \ [path_name] \ Program program_name.exe]

File: viewprnt. cpp

Line: 127

For information on hwo you program can cause an assertion failure,

See the Visual C ++ documentation on asserts.

(Press retry to debug the Application)

If the above information is displayed, it indicates that the toolbar for printing and previewing is not loaded. This situation often occurs when the static link library is used (use MFC in a static library ), dynamic Link Library is not a problem, but if you have to use a static link library, it will be in the Program *. add "# include" L. CHS \ afxprint. RC can solve the above problems.
