...any idea to overcome this problem?
any alternate method for checking the event logging process??
Plz tell me a solution.

Couple what you have with a "date/time since last check" flag.

Thnx David.
Eventhough itz a good idea ..real time display is not possible??
another problem with this is if two events logged in the same time one wil be losed.
I think the "event count " checking is more effective, isn't it?

Of course not. PulseEvent() only notifies once every five seconds.

Then this is a problem with the event logger itself, not your monitoring application. It should not matter when you check for new events, whether it's twelve times per minute or once per day, as long as the events are present in the log.

 Hi all,if i have a string,i.e : "jry1924",how to check whether it is a number or not?
I tried using function atof but if your string is not a number,it returns 0.
Help me pls!

The old fashioned way was to use strtoul and check the 'end pointer'.
But be aware if it is a very large number it will fail with an overflow.

Use strtod instead of atof. It has a parameter that points to first character in the string that it does not recognize as part of a number. If that character is not NULL (the end of the string) the string is not a number. It takes into account your current locale settings and exponential numbers.

have you given the thought of making ur own function? tis a little longer though!,if u like doing it from the basic,then this might intrest u.....
char a[]="jry1924";
int ch;
BOOL flag=0;
for(int i=0;(ch=*(a+i))!=0;i++)
{
ch-=48;
if(ch<0 || ch>9)
flag=1
}
if(flag ==0)
cout<<"NUMBER!"
else
cout<<"nope!not a number!";
cheerz.....

HI all!
I m calling a function by a pointer of an external class & that pointer has been defined in the parent class of the class from which the already specified function is being called. The pointer's class is linked with the parent class (through its header).
So, the scenario is that a function accesses the protected member of a parent class (pointer) & then uses that member to call a function.
Now, when i compile the code, LNK2001/LNK1120 error is thrown.
Can any body tell me y this problem occured & what about its remedy?
Regards
Usman Arif

External as in not part of your project ? Have you linked to the appropriate .lib files ?

External means another application.
infact, i m integrating the dll of my project in an application (external). Now, in the next step, i m trying to access a class from the external application. For this, i included the header in my project. It worked fine uptil now. But, when i try to access a function from that external class, the linking error was thrown.

OK, so you need to take the .lib file from when you build that external dll, and link to it.

Hello Mr arif,
you misunderstood MR Graus. He is saying that you forget to include .lib file which contain the runtime symbol for you external class(i.e. class from DLL).

The external application, i m using, has an .exe file as its output file.
I converted the output file to .lib file & then included it into my project, but the error is LNK1136 ,i.e. "Invalid or corrupt file".

Buddy I am here talking about .LIB file which will produce with the DLL (when you build it). you can find that .lib in DEBUG/RELEASE folder of DLL project

Friend!
That .lib file is already there, no problem with that.
My problem is that i wanna access the external application's (in which .lib of my project was included already)function from my project.
now, r u clear with my problem? if yes, suggest some remedy for it; if possible.

i can't seem to find matlab.h in my matlab7 folders or my visual stuido6.0 folders. Where can i get it
Thanks in advance

Do you have the rest of matlab, but not the .h file ? If not, then the .h file is of no use to you.
It sounds like you have it installed ( you have a matlab7 folder ), so do a system wide search for it. If you can't find it, I'd suggest that finding a copy of that file is a waste of time. If you're missing one file for some reason, you may be missing others, and a reinstall of matlab is the only sensible option IMO.

i think i have the rest. Do u think i can download it somewhere? Because i don't think reinstalling will help.

|

um.... dude, if reinstalling it won't help, then your setup is fundamentally broken. If that file is not in your setup, and you need it, then your setup file is broken, or you're looking for the wrong thing.
No, I've never used matlab. It's a library for image processing, right ? I have written a lot of image processing code in C++ and C#, but the only external library I ever used was paintlib, and GDI+ makes that redundant.

Did you install the MATLAB Compiler Toolbox? What about MATLAB C/C++ MATH Library?
Best regards,

What are you trying to do. I have MATLAB and a lot of toolboxes. MATLAB.h is not in my installation either. I have never run across anything that needs that include file.
If you are simply trying to call the matlab engine from your own program, you need engine.h. Also, look at the CP articles by A. Riazi and there is an online tutorial on Matlab's website.

Thanks for the response guys. I think I know what is wrong with the program. My friend emailed me this:
