Though I'd look at the sysinternals tool, as they're more digestible!

Hi anminxin,
Sorry I disagree with your code. I am asking how to get the preferred load address, but you get the actual load address. Any comments?

Hi,
I have a C code that calls an assembly procedure with a parameter that is a pointer to a structure.
typedef struct _SOMESTRUCT {
ULONG arg1;
CHAR arg2[10];
} SOMESTRUCT, *PSOMESTRUCT;
Then in C code, im calling an assembly proc like this:
SOMESTRUCT mySomeStruct;
ret = AssemblyFunction(&mySomeStruct);
In assembly code, how can i access arg1 and arg2?
Any idea?

OK - it has been a long time since I did any x86 assembly (remember int 21h, everyone?  )...
But presuming correct alignment, since you are passing the address of the structure, the first member of the structure (arg1) should be at that same address. The second member (arg2) should be at Address + sizeof( arg1 ) or Address + 4, if talking about a normal Win32 build.
Note that you should be specifying the packing of that structure, and I would suggest no padding (packing of 1) to make it easier to use the structure from assembly.
Peace!

Yes! And I have hazy recollections of int 13h as well.
And, of course, int 10h was where I got my start

I understand that. But please be more specific. You mean BP+4 in the stack?
|
|
|
|

IIRC, BP (base or frame pointer) is set to the value of the stack where your parameters are. So, yes, BP should contain a value that is the address of the structure, you will need to get to that address (start of the structure) and move past the first member of the structure to get to the second one.
Peace!

Hai !
Is the any other function other than fopen(), to open a file and write some data into it, as fopen doesn't work in my system!!

You can use CStdioFile (MFC) etc to do file operations and there are few others that you can try searching for
Somethings seem HARD to do, until we know how to do them.

I would say: "my application isn't able to take advantage of fopen", because I'm pretty sure fopen works fine on your system.

Actually it does if used correctly. Care to show us a code snippet?

TRY.log file is what i want to create
pchFilePath = ""c:\\Documents and Settings\\Kapardhi\\Desktop\\Oct22\\\\TRY.log";
CFile *fp;
fp = fopen(pchFilePath, "a+");
it gives unhandled exception error after execution of fopen ();

Why are you doing this?

So why do you not show what is happening after execution of fopen()?

that is the path where i want to create the file
At the end there are \\\\ i.e computer takes as
"c:\Documents and Settings\Kapardhi\Desktop\Oct22\\MyTry.log"
this"\\" implies any string before "\\" is path, and string after "\\" is the name of the file to be created

You totally missed the question. Why are you using the 2 extra backslashes?

While the compiler may excuse the "error" and the file is indeed getting opened, I would consider changing it to a single backslash to avoid any future problems.

You should create your own OS in order to fullfill such a requirement.
