This article mainly introduces how to debug VS2022 through Haikang camera fireworks identification SDK, the article is very detailed, has a certain reference value, interested friends must read it!

The following is the code I put into the VS 2022 version after debugging according to the Haikang official documentation code:

[general], select the additional inclusion directory on the right, click the down arrow that appears on the right, click Edit, and fill in the dialog box that opens as follows:

The header files of Haikang are placed in the D:\ ws\ vc\ emptycam\ hkheader folder, which are: DataType.h, DecodeCardSdk.h, HCNetSDK.h, plaympeg4.h.

Step 3: select [Linker] > [General] from the left menu. Select the additional library directory on the right, click the small triangle on the right, click Edit, and open the dialog box.

The folder D:\ ws\ vc\ emptycam\ hkdll is where the Haikang dll file is placed. The file is shown in the following figure:

Step 4: select [Linker] > [input] from the left menu. Select [additional dependencies] on the right, click the small triangle on the right, click Edit, and open the dialog box. Fill in the content according to the text in the picture.
