This is a piece of code I found in the web, and it works well.
But the DWORD var X define as "X dword ****b", I just want to make it a real X: input the binary(0 & 1) into a Edittext, and use GetDlgItemInt or GetDlgItemText to get it, I tried but failed.
How can I do that? THX. The snipplet is below:
.386
.model flat,stdcall
option casemap:none
includelib msvcrt.lib
printf PROTO C :dword,:vararg
.data
X dword 00011000111011110001001101100101b
dStr byte 10 dup(?),0
szFmt byte 'dec format = %sd',0ah
.code
start:
mov ecx,10
mov eax,X
xor edx,edx
mov ebx,10
f70:
div ebx
add dl,'0'
mov dStr[ecx-1],dl
xor edx,edx
loop f70
invoke printf,offset szFmt,\
offset dStr
ret
end start
In the snippet you posted the code from "start" to "loop f70" converts a dword value to a decimal string. It seems that you are asking how to convert a binary string input by the user to a dword value. I'm not aware of any procedure that does this in the MASM32 library, but the MSVCRT strtol (http://msdn.microsoft.com/library/en-us/vclib/html/_crt_strtol.2c_.wcstol.asp) or strtoul (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_strtoul.2c_.wcstoul.asp) functions can do it, or you could code your own procedure. The C source for strtol was included with the February 2003 version of the PSDK, and probably with later versions.
here are two procs in the masm32 library that handle the conversion in both directions. "byt2bin_ex" handles converting BYTE data to binary string data while "bin2byte_ex" handles the conversion in the other direction. Both algos are designed for streaming data at high speed and are larger than average because of their design.
