Use of get function in the GUI (Graphic User Interface)

Hello, I have a problem .I want to read data through a text box of GUI of matlab and this data happens to be in decimal and I want to convert into HEX data then I need to print that data in to text file in HEXADECIMAL format. This i m doing as below for get I m using following command tio read data from text box

X = get (hObject,'value');

then i m reading this value and converting it in to hex by following command

X1 = dec2hex (X);

then i am writing it to text file by following code

fprintf (fid, '%d ',X);

after doing this i should see result in text file but I m not able to see hex codes intead I m getting "0" answers.

Where is the problem.

Unless you need those character strings for some other reason, skip the dec2hex call and use

fprintf(fd, '%x ', X)

Thanks for the reply I did what u said but still it is giving answer as zero it is not working so now i feel that the problem is in get command.

Can U plz tell me what should be format for get command like if I want to read integer number ???

I have tried with strings but not it is reading it as character matrix of 1x3 size for 3 digit integer value..

fprintf(fd, '%x ', sscanf('%d', get(hObject, 'value')))
