Hi ALL

Can any body give me a solution(a kind of wrapper function) on converting a hex value into a BMP image.

My actual problem is , I have a table in the database in which one column contains Hexadecimal value. I need to take that Hexadecimal value and convert it into a BitMap Image.

Example hexadecimal value looks like this:
00481C017FFFFF0000000000007FFFFF0000000000007FFFFF0000000000007FFFFF0000000000007FFFFF0000000000007FFFBE0000000000003FFEAE0000000000001DF4AE00000000000014E00200078000003C100002000483F80024100002007C824F80243F00F3F0C4F3CCF82461831B199C9FCCCFFCC0C60E09344CCCF9308068066924CCCCF890803806CD34CCCC9990803006E59CCCCC9990FFFFFC24C4CFCC99904CD8C4EC7CC8

its raw hex string....
create a file, write a character for each 2 letters represented in hex....

for i=0 to len(whatstring) step 2
char2=mid(whatstring,i,2)
toWrite= int(hex("&H" & char2)
print #1,char2 || outputfile.write char2
next

make sure you save the file as .bmp
you can then use LoadImage or whatever to view it, you could do it with pointers and RTLCopymemory, but this is way easier
