How to use Visual C to compile only 1536 bytes of window programs

The old big brother told me ... // After compiling, the file size is: 1536 bytes / / pretreatment

#include

// Use the following pretreatment, must be a release method when compiling connections, otherwise you cannot pass // to customize the program entry, if you want to optimize, you can use this // If you use vs.net, you can set it: "Solve The program manager is selected, right-click, select "Properties" -> "Limited" -> "Advanced" -> "Entry Point" // VC 6 also has similar settings, but don't remember // Other settings for project properties can be taken carefully, and other optimizations can be set here.

/ / The following is the adjustment segment alignment, the default is 4K, can be loaded into the PE file faster in Win98, but will increase the size of the PE file // This line seems to be "invalid instructions", Therefore, it is also commented here, perhaps the reason for the paragraph is too small. / / Directly set directly in the project option: Item Properties -> "Limited" -> "Optimization" -> "Windows98 Optimization" -> "No (/ Opt: NOWIN98)" // # Pragma Comment (Linker, " / Opt: noin98 ") // The following optimization is the merger, not recommended, may not be used in many programs.
