The signature for the declaration and definition must be the same.
Use void time(float delms[][6]); in the header file.

Thanks,I changed the code to what you suggest:
declare:
void class:time(float delms[][6]);
define:
void class:time(float delms[][6]) { ...};
but the call:
time(delms)
not compile, giving error:
error C2664: 'time' : cannot convert parameter 1 from 'float ** ' to 'float [][6]'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
Please correct
Thanks

Thanks.
This is how delms declared:
float**delms;
delms = new float*[1000];
for (int i=0;i<1000;i++)
{
delms[i]=new float[6];
for (int j = 0; j < 6; j++)
delms[i][j] = 0.0;
}
|
|
|
|
|
In this case make the declaration and definitions as -
void time(float* delms[6]);
|
|
|
|
|
Thanks. It compiles.
Since the square brackets have a higher precedence than the de-referencing operator, this declares an array of 6 pointers to the type float
Any comments please?
Thanks

I would suggest you spend some time practicing reading declarations using the right-left rule[^]. It's invaluable to really understand what's going on.

It compiles. I run the function and it give me error:

Thank you.

times(float (*delms)[6]) will work.

my fault not having seen your code before.

As has already been suggested, please spend some time (here, for example) knowing the differences/similarities between arrays and pointers when using functions. Without that knowledge, you are going to continue to face the same struggles.
That said, have you tried:
void CCvib_procDlg::time(float**, int dim1, int dim2);
...
time(delms, 1000, 6);
I would refrain from naming a function time() as it could be confused with the time() function.

Hi Guys, It works!
Here are codes to share with you and thanks. In particular, DavidCrow and _Superman_:
float **tim_var;
tim_var = new float*[1000]; <<----------
|
for (int x = 0; x < 1000; x++) |
{ |
tim_var[x] = new float[6]; <<----- |
| |
for (int y = 0; y < 6; y++) | |
tim_var[x][y] = 0.0; | |
} | |
| |
for (x = 0; x < 1000; x++) | |
delete [] tim_var[x]; <<---------- |
|
delete [] tim_var; <<-------------------

Dear Sirs,
I am beginner in C++ and have problem with one my program.
I am C++ dll for protection my Expert advisor(Metatrader software).
I want make demo version for my client and want using time limit on that.
For example each client able use this software for 7 days and after that not workable for him/her.
I want simple code that check this time for me.
I am using win32 console.
Thanks.

1- Don't waste time on that. If your program is worthy enough, then it WILL be cracked/hacked whatever you do and you will loose a lot of valuable time working on "security" instead on the core business of your application.
2- Release a version of your software with a limited set of function and features with code REMOVED from the executable. (for example no save/export/report, limit the number of trade per day/hours, ...)
...
Watched code never compiles.

dear sirs,
thank you for your email.
I want use this timer in dll no in original source.
You know cracking dll is hard.
Thanks.

I second Maximilien suggestion. Anyway, you may write usage info, crypted, inside the Windows registry.

Can anybody tell how I get the window handle from a specific process Id. I got the process Id using GetCurrentProcessId()
Regards
Rajmohan

Which window handle? There are usually more windows belonging to a process (e.g. controls on a dialog like buttons, edit fields have a window handle too). Anyways, i assume you are looking for a top level popup window, one method would be to enumerate all the windows, for example using EnumWindows[^], on every window you could call GetWindowThreadProcessId[^] to get the id of the process the window belongs to and test for equality...

The handle of what window?
To retrieve all windows of a process, you have to call EnumWindows and, for each window, use GetWindowThreadProcessId to check if a window belongs to a process (the ProcessID of the window equals the ProcessID of the process).

EnumWindows function is working fine with all windows except my application. I will describe the issue in detail. I have a dll application and I have loaded it into App_Init folder, which loads for every application. I want to know which is currently loaded application and also I need to get the handle of the main window.
I used EnumWindows for navigating through opened application. It is calling for all the application except mine. I dont understand the issue can anybody help me.
Thanks in advance

There is no single window handle. A process may have multiple main windows, or none at all. So you have to enumerate all windows, and select the ones which have no owner, and the correct process id. Those will be 'main' windows of the process.
And before thou protests:
Yes, I know that in .Net there is a property called System.Diagnostics.Process.MainWindowHandle, but the implementation is just plain wrong.
