MSDN Sux !!!

Filter wont work cant find nada.

here i am again. Questions is for a loop or loop for fo some sort.

// I want to set all relays to 0(fl_set and 1 is on)
// By all relays i mean 1-25 relays
// So all 1-25 relays need to have 0
// was thinking of a loop to do this

EXP_USHORT Reset_All_Relais(int relay, int fl_set)
{
for relay (0 To 25)
{
return ScoUniSetRelay(relay,0);
// Simple be
return ScoUniSetRelay(1,0);
return ScoUniSetRelay(2,0);
return ScoUniSetRelay(3,0);
return ScoUniSetRelay(4,0);
return ScoUniSetRelay(5,0);
// etc etc till 25 LOL
}
}

cant find nothing in MSDN maybe it was another statment. Any idea guys what else can be used ?

Is this what you're trying to do?

for (int nRelay=1; (nRelay <= 25); nRelay++)
    ScoUniSetRelay (nRelay, 0);

Ahhhh yeah i think,....
What is this statement called in C++ For Loop ?

Can it be used like this.

EXP_USHORT Reset_All_Relais(void)
{
for (int nRelay=1; (nRelay <= 25); nRelay++)
{
return ScoUniSetRelay (nRelay, 0);

}
}

And what does my compiler means specificly with:
arning C4715: 'Reset_All_Relais' : not all control paths return a value
Linking...

no, what should the function Reset_All_Relais returns ?

now, the first time the function ScoUniSetRelay is called it will return the Reset_All_Relais function.

remove the return in the loop and place it at the end.

its suppose to give this back

return ScoUniSetRelay(relay,0);// for each relay the next
return ScoUniSetRelay(relay,0);// Number untill 25 including 25
return ScoUniSetRelay(relay,0);//
return ScoUniSetRelay(relay,0);
return ScoUniSetRelay(relay,0);
return ScoUniSetRelay(relay,0);

thats y i wanted return not at the end

PS: Suppose to give all tha back for the robo to set all the Relay back to off. ScoUniSetRelay(relay,0) 0=off relay for which one.

if you do that it will return on the first one, and never do the other ones.

EXP_USHORT Reset_All_Relais(void)
{
for ( int relay = 0 ; relay <= 25; relay ++ )

ScoUniSetRelay(relay, 0);
}

return

}

Something like this ?
B\c that is not working for me never used Loop n that stuff before so something is missing i think. ; gives me another error

EDIT !!!!!

PS: I dont need any return crap I can make the proto type run with out Return to check if it was or not just need to to make that damn thing do her stuff.

THANKS ALOT !!!!

i think you'd better take a piece of time to learn about at least C, or C++ if needed, because you really lacks in every basic knowledges on the language...

I wont argue with you but i do LOL.
I was assigned to this knowing be able to write it in java. But all the application adn control programs can only understand C++ or Pascal and some otehr machine language.
Truthfully i think i am getting the hang onf it though after the explaination of loop for.

=) !!!

My 8 page program is done and later ima go test it.
Worst thing that can happen the Robo pokes everything to oblivion hahah !!!!

Thanks guys

Please don't misunderstand me when I say this, but you should have a firm grasp of the basic C/C++ control structures and the return statement before embarking on your project.

This is what you need to do:

void Reset_All_Relays()
{
  for (int nRelay=1; (nRelay <= 25); nRelay++) {
      ScoUniSetRelay (nRelay, 0);
  }
}

If ScoUniSetRelay() returns a status, you need to decide how Reset_All_Relays() should behave if it encounters an error - i.e. should it interrupt the loop, ignore the error, continue with the loop but return the failure notification to the caller, something else...?

Yeah Took me awhile to get the grasps for what those things are. USHORT needs return value Void not etc etc Long and so =)

Now i can dig in C++ Not so much diff than java basics are same. just diff looks confused the hell outta me !!!
beside writing 8 page code and this is like 1 and half week on C++ for first time aint that bad huh ??? Maybe i am slow.

msnd works ... I searched this : http://search.microsoft.com/search/results.aspx?view=msdn&st=b&na=82&qu=for+loop+c%2B%2B&s=1[^]

how are the relays accessed ? is relay 1 the first one ? or relay 0 ?

for ( int relais = 0; relais  < 25; relais ++ )
{
  ScoUniSetRelay(relais  ,fl_set);
}

for ( int relais  = 1 ; relais  <= 25; relais ++ )
{
  ScoUniSetRelay(relais  ,fl_set);
}

return ScoUniSetRelay(relay,0);
return ScoUniSetRelay(relay,0);
return ScoUniSetRelay(relay,0);

thats y i wanted return in it the Machine responses to those commands.
if it gives out ScoUniSetRelay(15,0) relay 15 will turn off. i jsut wanted a collective command to turn all 0-25 off including 0

PS: Suppose to give all tha back for the robo to set all the Relay back to off. ScoUniSetRelay(relay,0) 0=off relay for which one.

I used CD MSDN

Hi folks..

Is there a way to read an exe file's version info, icon etc programatically
using C/C++ ?
e.g How do we read notepad.exe's version info via C/C++ calls?
thanks in advance..

can this info (gathered via getfileversion,extracticon) be used to set the

Nope, you have to use these api for Programmatically changing resource in other file :-
BeginUpdateResource,UpdateResource and EndUpdateResource.

And Here is article relating to above Api's

Convert path with spaces

Hi,

There has to be a library function that does this? I need to convert a path from say:
C:¥Program Files¥Mozilla Firefox¥firefox.exe
to
C:¥¥"Program Files"¥¥"Mozilla Firefox"¥¥firefox.exe

The reason is I need to pass the full path name to _spawnl

I wrote a simple function to do this, but is there a library function that already does this?

Thanks in advance.
