hi fellows .
I am developing an Anti-Virus software . and i want to have your suggestion and alternative .
so i want you to help ( or give me an alternative ) to how to search an Hex Value in a File .
i can do that in 2 ways :
1- Dump the File and save the results into a text file in a Temp directory , then use the simple Pos function to search for the Hex Value into this text file as some
AV softwares do .
2- Open the File with TMemoryStream , then use a function to convert the Hex Value into the String representation then use the Function Pos to search for the converted String Value .
but what i want is your alternatives , please is there any other suggestions to search for the Hex Value directly into the File without conversion or dumping .
waiting for all your reply .
regards Randy .
