how to calculate a runing time of program in "TICKS", in which computer calculates time of every thing. i m using simple Turbo c++.

ummmm
dwStartTickCount = GetTickCount(); // at the start
dwEndTickCount = GetTickCount(); //at the end
dwTicksToRun = dwEndTickCount - dwStartTickCount;

How to make a license file which makes the application expire after a specific date, and also how to stop copying the .exe file.
|

I'm sorry, but you're basically asking for someone to write you an article. You should post such questions to the article suggestions forum.
Do you know how to open and close a text file ? Use the registry ? Find out the current date/time from the system ? How do YOU think such a system would work ?
There is no way to stop people from copying a file.

Hmmm... maybe they'll add that to force us to distribute all our apps by ASP.NET......

Forget about 'expiring' if you're trying to protect your shareware app. Cracker d00dz will be able to break it very easily.

Hello all.
I'm now creating a ActiveX control using mfc ActiveX control wizard.This control draws lines and arcs defined. Can I export my classes in this project? how? Thank u for any suggestion!

I know that it provides IHTMLEventObj for access event process.
But I don't know how it acknowledge me when event occured.
|

can a variable be inserted into a structure(declared in some header file and containing some variables) during run-time? If yes, how?
|
|
|
|
|
I doubt it. You're asking an application to change the size of a class within itself. That's a big change.
Why would you want to ?

Do you mean a self-growing array like std::vector()?
You can't change the declaration you gave to your compiler, this is compile-time.
But you can declare 'here is a pointer to any amount of memory'.
Strings do this all the time.
Or you can declare 'here are any number of XY objects': this would be a std::vector.
I hope this helped

When IE connect to a website using SSL,IE will display a dialog to ask user to select a certificate of him(or her).
In fact,IE connect to the system's CSP and search user's certificate.
my question is:
if my certificate is stored in other place,but not in the system's CSP or a SmartCard,how can I have IE use my certificate when it connect to a SSL website?
For example,I store my certificate(and private key) in my own USB card,which is not compatible with the SmartCard.What can I do?
I think that if I can hold up the event which occur when IE connect to the system CSP for requiring a user certificate(and private key),it will be simple!
thanks advance!

Hi I had a structure which looks like this:
1.
struct CMyStruct
{
5-6 CString ...;
int ...;
long ...;
1 CStringArray ...;
};
2.
My application is going to generate a lot of instances of CMyStruct; I therefore thought it to be a good idea to use the CArray MFC template class to *manage* my structs. (Adding, deleting etc.)
3.
Accordingly, I put the following definition in my dialog header file.
#include <afxtempl.h>
#include <Mystruct header file>
CArray<CMyStruct,CMyStruct&>MyStructArray;
4. After this I began using it in the following manner:
CMyStruct myStruct;
PopulateMyStruct(&myStruct);//Structure populated
MyStructArray.Add(myStruct);//ERROR PRODUCING LINE
5. On compilation i receive the following error:
\INCLUDE\afxtempl.h(443) : error C2582: 'CMyStruct' : 'operator =' function is unavailable
C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\xlocale(467) : while compiling class-template member function 'void __thiscall CArray<struct CMyStruct,struct CMyStruct &>::SetAtGrow(int,struct CMyStruct &)'
6. What could I be doing wrong??
Any help would be greatly appreciated.

Imlementation of SetAtGrow method uses an operator =. You need to implement one for your struct/class.

does CMyStruct have an "operator =" member ? looks like that's what the compiler wants.
have you considered std::vector instead of CArray? overall, std::vector is a nicer way to deal with an array of things.

hi there,
just wanted to let you'll know:
When i remove the CStringArray from the structure it works!
|
|
|
|
|
This is because of CStringArray has no "=" operator.
Best regards
Holger Persch
|
|
|
|
|
OK thats fine, but what happens when I **NEED** a CStringArray in my structure.
(Right now i have replaced the CStringArray by a char**) but thats not very elegant!)
|
|
|
|
|
then you need to write an "=" operator for your struct. in it, you'll copy all the data items from the input struct to "this".

|

Do you mean implementing a = operator that copies from one CStringArray into another.
P.S:I say this, because i am now using a statically allocated char[][], thereby eliminating the need for copying!
