If I have a ten byte mem chunk that contains the following:
00 00 01 31 05 DB 0A 45 68 F3
and the first four bytes designate the IPX network number and the last six bytes designate the MAC address of the network card, how would I convert this straight into the format:
00-00-01-31:05-DB-0A-45-68-F3
for displaying in a MessageBox or the like.
I tried wsprintf with this as the template:
%02X-%02X-%02X-%02X:%02X-%02X-%02X-%02X-%02X-%02X
but it comes out crazy like this:
00-00-00-01:31-000000-05-0000-56
or something. Am I missing something? I dumped the mem block into a file and checked it with a hex editor and it looks just like at the top of the message. thx.

I think you should use an lstrcat.
I think this should work. storage must be in .data? section. completestorage can be in .data, and is the string in which you are going to add storage, for example: "completestorage: storage", so: "address: 05....etc".
Tell us if it works or not. Sorry if this is not correct, just tell me if not, and i will check it again.
See you
invoke wsprintf,addr storage,addr szformat, addr string
invoke lstrcat, addr completestorage, addr storage

rdaneel, that looks right, but try this, too?
%.2X-%.2X-%.2X-%.2X:%.2X-%.2X-%.2X-%.2X-%.2X-%.2X
I have a project here that uses:
"%s, %lu, %lu%.9lu !"
...and it appears as expected.
Edit: Whoops, forgot that wsprintf doesn't truncate numbers that are bigger, so it's trying to convert a 32-bit number in each case and filling the possition with as many significant figures as it has or two - which ever is greater. This won't work - ignore me. :grin:
From the PSDK:
The width specification never causes a value to be truncated. The value is not truncated when the number of digits exceeds the specified precision

Each of the bytes must be expanded (zero padding) to a DWORD before they are used as arguments to wsprintf.
tank is correct.

Either a DWORD address of a string in mem. or a DWORD integer value but it has to be a DWORD value for each argument. That makes sense. Most all the functions in the api take dword arguments don't they. Thanks again.
