Help with Autoit Plugin...

[Cyberworld]

I want to add a command to my plugin that returns an int from a memory address. I use AU3_GetInt32/AU3_SetInt32 to get/return the values, but I have not been able to make it return the actual contents of the specific address. I need to make a cast but how should that look like? The compiler just complain about all my attempts to do any

The command is supposed to work like this:

$file = FileOpen("Data.dat", 0)

$buffer = FileRead($file)

FileClose($file)

$data = GetInt($buffer+4)

Lets say my file contains the data: "TEST12345678". After executing of my command [GetInt(adress)]

$data is supposed to be equal to 0x12345678.

Think that code through. You open a file, read it's contents as a string into a variable and close the file. Then you add 4 to the contents of the string mathematically. In most casts that's going to produce the value 4. At any rate, whatever the calculated value is, it's passed to your GetInt() function. But you claim your GetInt() function is expecting an address.

Are you sure you're ready to be writing plugins? Are you sure you're ready to be reading raw memory addresses arbitrarily?

and I'm "almost" sure that the ASCII string "12345678" will not be equal to 0x12345678. I'm not 100% sure, but the compiler keeps complaining

I'm surprised this user knows how to read memory addresses. Can you tell us what you are reading for?

The test12345678 was just an example. It's not an ascii string. The file contains header $52494431(RID1) and then the number of entries $0001766e... etc followed by some other datafields...

Yes you are correct in that case. I just add 4 to the string. But if I read my data to the string are there any way to get the pointer to the memory area that the string occupies? I could alloc some memory and read the file directly from my plugin (The filehandling are already there for other things like streaming of data to the CRC32 routine & for a precompressor) but I since I want to return several values in this case do I think it would easier to handle this from AutoIt directly.

You are adding 4 to an ASCII string is their point. Adding 4 to a string, is not going to get you the "address" in memory. I don't know what made you think that, and quite frankly don't care due to the incorrectness of the information.

The question(s) still beg's to be answered by you: Why do you need to be playing with the memory address? What are you trying to accomplish?
