Look at BitBlt or StretchBlt.

Basically, you create two DCs and select the source and destination bitmaps into each on and Blt away.

How to list all installed programs of my windows?

I want to list all the installed programs like control panel Add/Remove programs. I know all the items would be list in the registry path:

'HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall'.

But, the problem is, there would be too many items if I enumerate the key, all system update packages and other small applets included,too. I only need basic information of the installed programs like control panel do, how to do that?

Thanks

What you want is just not possible. Windows does not know about all programs that you have installed (especially the older ones), only the ones that have gone the "standard" route and updated the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall key.

The Official method (used by "Add/Remove program") is with COM interfaces)

Unix to WIndows Message

My Windows MFC Application will receive a structure from a Unix machine (Big Endian) over UDP.

The structure has the following data types:-

struct RXData {
      double    timeStamp; 
      double    item1;    
      long    item2;       
      double    item3;      
      int	 flag1;    
      bool	 state;  
};

What do I need to do on the Windows platform to get the data in the correct format; i.e. do I use procedures like theses below - I did try but still not getting the correct answer.

float swap(float d) 
{ 
    float a; 
    unsigned char *dst = (unsigned char *)&a; 
    insigned char *src = (unsigned char *)&d; 
    dst[0] = src[3];
    dst[1] = src[2];
    dst[2] = src[1];
    dst[3] = src[0]; 
    return a; 
} 

short convert_short(short in)
{
    short out;
    char *p_in = (char *) &in;
    char *p_out = (char *) &out;
    p_out[0] = p_in[1];
    p_out[1] = p_in[0];  
    return out;
}

The floats give incorrect values.

Any suggestions for this simple scheme please. Confused | :confused:

Regards,

Andy.

Actually you need to convert doubles, not floats (i.e. 8-byte values instead of 4-byte ones).

you said the struct holds doubles, yet you show a swap function dealing with floats, not doubles?
apart from that, everything looks OK. Although there are other schemes, some involving a union.

I cannot find a 'useful usage' of a union to reverse byte order (while I highly appreciate unions as 'variants').
