Hi
1) Yes, it is possible to pass arguments to a batch file. You use %number to get the argument by counting. For instance:

REM batch.bat
echo %1
echo %2
REM batch.bat

Now you call it "batch.bat Hello World" and the output is

Hello
World

If you have "echo off".

2) A better one =) I call the application from the prompt line, instead of just clicking it. This way, when it finishes, the window is still open and I can see the output.

Below is the batch file I created. This batch file is used to run a command line exe which takes some parameters. Most of the time, it works with two parameters one for input file and the other for output file.

For example
C:\>myapp.exe input.txt output.txt.

I am just doing the execution using a below batch file.

REM xxx.bat
@echo OFF
%1
%2
%3
%4
myapp.exe %*
pause

But while executing batch file
xxx.bat input.txt output.txt

It opens the input.txt file and after closing the input.txt file it starts executing the myapp.exe with the given paramters.
I don know how to stop opening the input.txt, so that it will not open the input.txt and rather just executes the myapp.exe with the given parameters. Can you please help me to stop opening the input.txt file while executing the batch file.

Thanks,
Nandu

It opens the file because of these lines:

%1
%2
%3
%4

You should write only:

REM xxx.bat
@echo OFF
myapp.exe %*
pause

If %1 is equal to "input.txt", them writing %1 just like that will open input.txt with the default application (usually notepad).

Hope i'v helped =)

You can use something like this:

#define next(i) ((i) < 5 ? (i) + 1 : 1)
#define previous(i) ((i) > 1 ? (i) - 1 : 5)

int main()
{
	unsigned i, aux, j, cnt;

	for (i=1 ; i<6 ; i++)
	{
		for (aux = next(i) ; aux != previous(i) ; aux = next(aux))
		{
			cout << i << aux << next(aux) << endl;
		}

	}

	return 0;
}

The "next" macro increments a value until it reaches 5. When such happens, it returns to 1. The "previous" macro does the opposite, when the value reaches 1 it returns to 5.

setting static IP address using win32 API

In what format? You can always output the XML tags with the values... I just don't know for sure which tags you intend on using.

you could try to have a look at the ip api... but most of it is pretty undocumented, so good luck Smile | :)

sounds like a disaster in the making to me mate.

hard coding an IP address is going to fall over sooner or later depending on the network config.

i would ask if u really need to set a static IP addr or weather u can use a "localhost" type workaround
