The method which is delivered a variable 'i'.

hi Antonio

Make a Colsol Mode DLL program.
The method which is delivered a variable 'i'.

It is possible ?

This portion of your code is an endless loop that will hang your application:

[Antonio Linares]

Is it working ?

If not, what error do you get ?

[yunbg1]

Sees the c++ source cord and it will be able to own jointly place this there is a g_Num variable from the FWH?

[Antonio Linares]

To assign the high level g_Num variable do this:

ACTIVATE WINDOW oWndC MAXIMIZED ON INIT ( g_Num := MMP_INIT(), timer() )

and add this in your C++ code, after final g_Num ++;

Code: Select all  Expand view

hb_retnl( g_Num );


[yunbg1]

Hi Antonio Linares

Thank you.

But.

'Process BAR' It makes from the (FWH + Habour OR FWH + xHabour).

If it is like that and 'MMP_INIT()' continuation after executing 'g_num'
the change comes over and process it will embody the bar to put out,

it isn't ?

Reply the execution is over now and completely
it comes out and 'g_num' the change to go over and it isn't to come ?

[Antonio Linares]

I don't understand what you mean, sorry.

Please show an example or explain it in a different way, thanks

[yunbg1]

Hi Antonio Linares

Thank you.

I will make 'Process bar' from (FWH + Harbour).

Then, I execute 'MMP_INIT()' and after that 'g_num' changes have to come over untill
I close the Program 'MMP_INIT()' that I can make 'Process bar'

This is (FWH + Harbour) code.

This is c ++ DLL code
'g_Num' Variable declaration method ????????
And the method which owns jointly the 'g_Num' with the FWH code.

[Antonio Linares]

public g_Num

...

ACTIVATE DIALOG oDlg CENTER ;
ON INIT ( timer(), g_Num := mmp_start("test.txt") )

...

oMeter:Set( g_Num )

Or do you mean that you want to update the meter from the C++ function ?

[yunbg1]

It calls a C++ DLL function from the FWH and it wants indicating a g_Num variable.

It wants embodying a 'Process BAR' from the FWH.
