I want to respond differently when I choose Print from the menu and the Print button from the toolbar.

Connect them to different triggers.

I want to draw menu without the shadow frame, but i don't know how to deal with the frame of the menu. I searched but only found one project Professional User Interface Suite[^] implemented this. But, the project is so huge, so, i almost can't find how it reaches its aim.
Any ideas will be very appreciated.

You can use the URLDownloadToFile[^] API.

You can use the Windows API: UrlDownloadToFileA or UrlDownloadToFileW .

Please read the posting guidelines before posting on this message board (this is the message called "How to ask a question").
Points which require your attention:
1) Formatting of the code (use the code tag to format code properly)
2) No clear description of the problem (please provide details about it)
3) You say there's a "abnormal essage", then give the exact error message and in which conditions it occurs.

You still didn't provide a lot of information. What is the exact error message ? Did you try to debug to see where your code causes problem ?

Sending array through pipe

24-Nov-09 14:17

I have tried to debug. when it runs to the
" glFogCoordfEXT(f1); ",the program stops.
this is the error message:
AppName: fog.exe AppVer: 0.0.0.0 ModName: unknown
ModVer: 0.0.0.0 Offset: 00000000

Can you send an array of longs through a pipe? If it is possible, how would you do it?
Thanks in advance.

Typecast the array to whatever data type the function to send expects and give sizeof(array) as the size to be sent.

double a = 0.0000005;
char aa[50];
sprintf(aa,"s%lf",a);
printf("%s",aa);

Output:s0.000000

In the above code snippet, the variable aa can contain only 6 decimal precision. I would like to get an output "s0.0000005".
Could you please advice me on how to achieve this?
Thanks

See the MSDN documentation on printf format options[^]. It contains all the details of how you may customise this to your exact requirements.

I was hoping that my reply would encourage them to actually learn something beyond how to print to seven decimal places!

If they really want to, they will learn more after wondering what 9.7 means.
Otherwise they will never learn no matter what.

Just my opinion. Smile | :)
