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);
}

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 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..

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.

tsss,

no need to do this D'Oh! | :doh:

the strings using doubles \\ are because when you code, the single \ is used as the escape characters.

but if you get the path from say an edit box, the \ (written alone) are in the same format.

in brief, you need double back-slashes only in design/coding time...

You know, it's really weird, but with _spawnl I had to do this for it to work otherwise I got all these weird errors.

Anyway, I have just found the wonderful function CreateProcess().

Thanks!

Re: Convert path with spaces

toxcct29-Jun-05 1:22

toxcct

29-Jun-05 1:22

but where did the string you were passing to _spawnl() come from ?

your source code ? or was it an entry the user passed to the program ?

anyway, you can use - for example - this functions :

CString strPath;
 
<font color=green>//strPath been filled here, with single back-slashes...</font>
 
strPath.Replace(<font color=gray>"\\"</font>, <font color=gray>"\\\\"</font>);    <font color=green>// Replaces every \ with \\</font>

have you tried putting the entire path inside double quotes ?

csPath = "\"C:\\what ever\\file.exe\"";

just a thought.. don't know if it'll work or not

Thanks for the answers everyone. I moved to using CreateProcess() which just accepts a path like:
CString path = _T("\"c:\\path with spaces\\file.exe\"");

with _spawnl() I had to put quotes around every path element with spaces in it like so:
CString path = _T("c:\\\"path with spaces\"\\file.exe");

see if SetCapture[^] solves your problem, or else check with hooks[^] if they help.

If you're already drawing a rectangle on the desktop when your app is minimized, then you already have a solution.

Otherwise you could write a system-wide mouse hook.

opening word and passing strings to a word template doc

Hi,

I was wondering if any of you know how to open microsoft word in C++? i need to pass strings out to a template word document to fill in.

Much thanks,
(john.parr@logicacmg.com)

I know the VB script method:

'Used to open word and populate CD label values in a word template'
Dim oWordApp
Dim oWordDoc
Set oWordApp = CreateObject("Word.Application")
If oWordApp Is Nothing Then
MsgBox "Couldn't start Word."
Else
oWordApp.visible =true
Set oDoc = oWordApp.Documents.Add("C:\cdtemplate.dot")
with oDoc
.bookmarks("mainTitle1").Range.text="HELLO"
.bookmarks("subTitle1").Range.text="TEST_DATA, PLAN_TEST - 393"
End If

You'll need to use automation. Make a search on the MSDN site (here[^]) about the subject Word automation.

I think once you get the object, the methods will be the same as in VB.
