MsiProcessMessage MessageBox Style

[esiemiat]

I am using MsiProcessMessage to display an error message in one of my installscript custom actions. The help indicates that I should be able to use any of the MessageBox constants such as MB_ICONQUESTION, MB_ICONWARNING, and MB_ICONINFORMATION. However, these are not recognized by the compiler. What should I use for these constants in an installscript CA?

Perhaps try:

#define MB_ICONERROR          0x00000010
#define MB_ICONQUESTION       0x00000020
#define MB_ICONWARNING        0x00000030
#define MB_ICONINFORMATION    0x00000040
