Convert string to integer array

[JohnSantaFe]

Hi,

I'm reading a packet with TCP Read.  The data out is a string o 248 bytes.  I need to convert that to an array of  62 U32's.  I tried type casting in a loop but that didn't work.

What's the correct way to perform the conversion?

Thanks.

Just typecast to a U32 array. No need to use any type of loop.

there are string convertions uder the string pallette that may help

Why would you go through a string?

To original poster: As Dennis indicated, you do not need a loop. Byte endianness may be a problem, though. Do you know what this is for the source data?

I'm using a string because that's what TCP Read's data out is.  Is there some way to change that?

When I simply type casted, all I got was a single value I did not get an array.  I think the single value was simply the first four bytes of the string. That's why I tried a loop.

I think I'm misssing something with type casting.

Smercurio_fc is right. I forgot about the endianess. Instead of the type cast, you could use the Unflatten From String. Depends on what is generating the data.

No, the TCP/IP Read output is only a string.

You definitely did something wrong if the type case did not return an array. Are you sure you have a U32 array wired to the type input?

Ah that's it.  I had wired just an integer to the type for the type cast and not an integer array.

Thanks to everyone for your help.
