Magic has solved the problem that you do not want to investigate for the moment, but it is necessary to write down the problem that you cannot find the VCR debugging library.

In a Win32 solution (unmanaged C ++), when you change the startup project, always report"Msvcr80d. dll not found".

Because we are sure that both DLL and Lib exist, we tried a very bad solution.

1. Comment out all source code in the newly switched startup project,

2. Write an empty winmain with only one system pause statement;

3. f5.

4. Normal Operation

5. Reverse operation 2, reverse operation 1.

6. OK

The suspect is related to the encoding of the text editor. Writing a new winmain in the blank CPP of a blank project will occasionally fail to be found .. (1)

CTRL x drop winmain, and then F5, a link error will be prompted. The entry function * winmain * cannot be found *.

CTRL v winmain, then OK.

When (1) is encountered, it is rare to press one or two carriage returns after.
