Here comes some computing history:
A nibble is 4 bits
A byte is 2 nibbles = 8 bits
A word is 2 bytes = 16 bits
A double word (DWORD) is 2 words = 4 bytes = 32 bits

So your structure will be 8 bytes.

Dear mike and TonP,

Thanks for the responses. I tried with all your suggestions.

In the dll call, the return value show some error. kindly see the attachment please.

Error: One or more of the supplied parameters are incorrect.

Kindly check the dll call and please give me the correct input values.

P.S. (msdn.microsoft.com/en-us/library/aa379804.aspx )

Thanks,

There are no string outputs in my solution (not everything that is pink is a string!). For each number, I create an array of U8, and since each can be of different length, I package them into an array of clusters. (If you would autoindex to a 2D array, the short solutions would get padded, something you probably don't want).

Dear altenbach,

Thanks for all the replies. Also, now i need to implement another one. Let's say input be 2,1 2010010100 from the text file. I need to convert these into an array of U8. When i tried with ur example, the ',' and ' ' (space) are skipped and it results in an array like this 02012010010100 (omitting , and space).

How to implement this?

Thanks,

Mathan

This is because I read the file as a 2D spreadsheet with space as delimiter, meaning the first colum will have the "2,1" and the second column the "201..." string that is further processed. Since the spaces is defined as delimiter, it is dropped.

If you want the entire line as one element, define a diifferent delimiter (e.g. \n).

Maybe you should also explain what you mean by U8 array. Just the byte representations of your formatted string?

Dear altenbach,

Thanks a lot for the post.

As per the vi attached sending the string '2,' as input, hexadecimal string to number function is converting it to 02 (omitting the ,). Similarly, 1 (1 space) if given as input will return as simply 01 (omitting the space). i need if input string is 2,1 2010010100 the output will be array of U8 values. what am getting now is 02012010010100.

Thanks,

Mathan

Please attach the VI instead of an image.

Since you want the plain string, delete the inner loop and use the raw string directly. Try it!

Its actually the vi you posted in this thread named scanhex.vi. so i didn't reattached it.

No altenbach, am not in need of string output. i need the output as 02h, (comma)h, 01h, (space)h, 20h, 10h, 01h, 01h, 00h (all must be U8 values). am attaching vi here. kindly modify please.

Thanks,

Mathan

Hi Mathan,

Can you attach the file also, or save & repost the VI with default values for the all rows variable?
