LabVIEW: Memory or data structure corrupt.

[vgezer]

Hello everyone,

I know, this will be a very simple question, but I could not solve this. When I entered a text to text control box in Hexadecimal. I want this text to be converted into hexadecimal number. I am using unflatten from string function.

If I enter 8 characters it causes no errors. For ex: 1234 5678.

But If I enter 1234 for example, it causes the following error:

LabVIEW:  Memory or data structure corrupt.

How can I solve this problem? Thank you and best regards,

I'd try the "Hexadecimal string to number" function.  That should work as long as your string contains 1 to 8 hex digits.

Hello,

Thank you for your response but no output is given after I try this function. Please find the updated file on the attachment.

The error that you are getting with Unflatten From String is because this function is made to get as an input a flattened string that is typically generated by the flatten to string function (please refer to LabVIEW help if you need more informations about this function). I attached an example with several functions that you can use. You can use also the function type cast.

Have you tried changing the format of the string control to hexadecimal?

@Carmen: Thank you, it seems it is working if the string representation is normal text, but I need to use it in Hexadecimal representation.

@mikeporter: Yes it is already in Hexadecimal format.

Take a look at this example, see if you can get some ideas out of it:

Have you tried Type Cast it to U16 array? That way you get decimal value of each 4-digit word.

Hello,

Thank you. I will try and tell you the result tomorrow...

Hello,

I would like to explain my aim again.

I would like to create a MAC address from the serial number. For example in Serial Number Field, I am writing 1203 and the MAC address becomes: 000A 3500 1203. I would like to generate a report using Easy Text report and would like to print both Serial number and the MAC address in Hexadecimal.

I try to connect MAC address indicator directly to the report text input. When I print, only string representation of the MAC address is printed (e.g. ..s).

How can I make this to be printed successfully?

Thank you again...
