(C++)Appending .zip to .exe using Chilkat 9.4.0 - unable to compile/link -
i'm trying "join" .exe file , .zip file method educational purposes. borrowed code here: http://www.chilkatforum.com/questions/2354/how-to-write-a-self-extractor-for-the-windows-os . code:
#include <windows.h> #include <ckbytedata.h> #include <ckfileaccess.h> int main(int argc, char* argv[]) { const char *exefile = "c:/program.exe"; ckfileaccess foo; int exesize = foo.filesize(exefile); int nzeros = 4 - (exesize % 4); if (nzeros < 4) { ckbytedata zeros; zeros.appendcharn(0,nzeros); // append zeros .exe zeros.appendfile(exefilee); } // append .zip .exe ckbytedata zipdata; zipdata.loadfile("c:/mine.zip"); zipdata.appendfile(exefile); return 0; } these header files:
