To.Ulong Bug????

[tssing]

To.Ulong({{0,0,0x60,0xc0}})correct

Private.c[0]=0

c[1]=0

c[2]=0x60

c[3]=0xc0

To.Ulong({{c[0],c[1],c[2],c[3]}})//error

To.Ulong({{0,0,StrToDouble("0x60"),0xc0}})//error

Please check it ..

You cannot put expressions inside of {}, only constants. If you have a variable loaded, you would just do:

To.ULong(c)

I use the example of statement

I think you no read usersguide.pdf....I use example of this file....

[tssing]

I very angry..You every day give me many execuse...And not help to me...

[AzeoTech]

Actually, I wrote the user guide, so I can assure you I have read it many times. No where does it say that you can use variables inside of {} notation. Only constants are allowed:

OK:

{{1,2,3,4}}

NOT OK:

{{C[0],c[1],c[2]}}

On page 44 of the users guide it says exactly this:

Only numbers and commas are allowed between the {}, but these numbers can be in hex or binary format using the appropriate delimiter described a little later.

What you want is simply this:

Private.c[0]=0
c[1]=0
c[2]=0x60
c[3]=0xc0
To.Ulong(c)

because c contains the whole array already.

Only constants are allowed.......

I think this function not good for used.

I think you are misunderstanding. Only constants are allowed inside the {} notation. This is identical to C / C++ (except C has #defines, which DAQFactory does not). In the To.ULong() function you can use variables all you want. The primary use is for parsing serial data. So, if you were reading 4 bytes from the serial port into a string that specify an unsigned 32 bit value, you could do:

private string datain = Device.myserial.read(4) // read 4 bytes

private val = to.Ulong(asca(datain))

The asca() function converts a string into an array of bytes. So, asca("abcd") returns {97,98,99,100}.
