Thanks a lot.
My problem with automation is that I don't understand type Variant very well and all of the parameters to automate a document has Variant types.

Friends,
I like to send ARP request packets and ARP reply packets on my network. I want to use Visual C++ and winsock for this purpose. How can i do so ??? Please tell me any method suitable for this purpose you are aware of or any resource. There exists a function in Windows2000 SendARP() but it only sends ARP requests and available on windows 2k+ only. I also want to send ARP reply packets.

Hi...
Can somebody pls guide me on how to do d above for information stored in a structure. I know it's sthg to do with fwrite but how should I construct d code to read from the struct and store in file.
Thank you

struct
{
char szName[25];
char szAddress[25];
char szCity[20];
char szState[5];
int nZIP;
int nAge;
} Demographics;
FILE *pFile = fopen(..., "wb");
fwrite(&Demographics, sizeof(Demographics), 1, pFile);
fclose(pFile);
...
FILE *pFile = fopen(..., "rb");
fread(&Demographics, sizeof(Demographics), 1, pFile);
fclose(pFile);

Also the structure need to be #pragma pack/unpack ed

Possibly, depending on the layout of it. In the example I provided, packing was not needed.

Hi again...
Thanks for d info...I guess I've got d method rite after all. But I couldnt seem to get all d data stored correctly upon reading the binary file.
Here's how I did it...
struct{
...
} Demographics;
Demographics demo = new Demographics [1000];
FILE *pFile = fopen(..., "wb");
fwrite(demo, sizeof(Demographics), 1, pFile);
fclose(pFile);
...
FILE *pFile = fopen(..., "rb");
fread(demo, sizeof(Demographics), 1, pFile);
fclose(pFile);
The value of '1' in fwrite(...) should reflect the no of records I have in d struct rite? But how do i ask the program to detect the it's value upon opening the file? Is there a function that can do that? Or do I have to create a header to the file to specify the number of records in d file?
Thanks again...
Rgrds.

Your code is incorrect. The variable Demographics is not a pointer so using new is in error. If you want 1,000 of them, simply use:
struct
{
...
} Demographics[1000]; Ming Yan wrote:

Correct.
Ming Yan wrote:

If the size of the structure is 78 and the size of the file is 468, you know that there are 6 records.

There's nothing wrong with this idea.

Hai all,
i was just practicing Layered Windows. So i created an MFC dialog based application and then proceeded. But when i try to call SetLayeredWindowAttributes () function, i got an error that the compiler cant find the function. When i look MSDN, the function is defined in windows.h and as its an MFC app, i think that there is no need for including windows.h header file.
But my compiler is stilling telling the error that it cant find the function. I had latest platform SDK installed and the Include path of visual studio is also updated. Im working in Windows XP.
Please help me.
Regards,
Jijo.

don^t know which MSDN library you looked at but mine says it is declared in
wingdi.h
AND you need to link to the library user32.lib
hope this helps you

Thanks for the reply. But the solution was not that. Just now i got the solution.
I searched the header files for SetLayeredWindowAttributes constants and found that they are only defined if the _WIN32_WINNT is >= 0x0500
#if(_WIN32_WINNT >= 0x0500)<br />
#define WS_EX_LAYERED 0x00080000<br />
<br />
#endif /* _WIN32_WINNT >= 0x0500 */
so i just added
#define _WIN32_WINNT 0x0500
and it worked...
And i dont know whether its the right method.
Regards,
Jijo.

Can anyone give me a broad overview of skinning through the use of XML files? Any help would be greatly appreciated. Thanks.

XML only holds the skin information... Skining is done my Visual C++.

Who can advice me about website that teach about C++ Programming On Mobile
I use CodeWarrior on Symbian OS 
Thank you very much

You should visit NewLC-website. It is dedicated to Symbian OS development and covers a few of the platforms available.
You cain find it from: http://www.newlc.com/[^]
Alternatively, you can use Visual Studio. There are instructions on how to do this around the Net. Developing for the Symbian OS with C++ is, for some reason, troublesome. Most of the SDK implementation ideas are extremely bizarre

Im going to make a console project... don't ask... and I need to add command line arguments, im using windows xp, and somehow when I add the command line arguments to the end of the filename e.g. somefile.exe /something it says "/" and a bunch of other characters aren't alowed to be used... has windows xp completely taken off command line arguments?? sry its just that the last time I had command line arguments to one of my programs was when windows '98 came out.

#include <stdio.h>
int main(int argc, char** argv)
{
for (int i = 0; i < argc; i++)
printf("Arg %d = %s\r\n", i, argv[i]);
return 0;
}
This small C program will dump the args. The process of receiving args for console apps hasn't changed a bit

Oh yeah. If you're wanting a string with spaces, enclose them in quotes to get a single argument, e.g., long filenames with spaces:
<nobr>someprog.exe /v /n:5 "c:\my program data\my file data.txt"
The above yields 3 arguments passed to someprog.exe, plus somearg.exe itself.
arg0 = someprog.exe
arg1 = /v
arg2 = /n:5
arg3 = c:\my program data\my file data.txt

are you doing this on windows xp.. because for me it says / and some other characters are illegal to use

I have written a sample application to catch the WM_DEVICECHANGE message and it works well.
Now I tried to move the same functionality into a service so I create the service and the service creates an instance of a class which I defined that extends CDialog (called CMessageHandler).
CMessageHandler m_MessageHandler;
m_MessageHandler.Create(HIDDEN_DIALOG, NULL); {This returns TRUE, I checked}
CMessageHandler is supposed to handle WM_DEVICECHANGE event but it doesn't. I have declared it in the message map and I have created the necessary OnDEviceChange function but the messages never seem to be caught. I'm sure I'm doing something really stupid here.
Any help would be greatly appreciated.
