Value of a String Variable is found to be corrupted

Question ID: 106479

Value of a String Variable [char *Variable] is found to be corrupted after web_reg_save function call is made.
If a statement lr_output_message("Value: %s",lr_eval_string(Variable )); is written before the web_reg_save/ex code block,the actual value of the variable is printed in the output.

But if the same output statement is written after the web_reg_save/ex code block, a garbage value is printed.

I have tried this from multiple machines and tried clearing the old script result files as well, but the issue still persists.

From looking at your description, it appears that you are trying to use a pointer to a string while working with the web register save function calls. These functions do not return a pointer to a string. They return a pointer to a structure of type LPCSTR. This is why you use lr_eval_string to print parameter values. The following is an example: ...
web_reg_save_param(''Parameter'', ''LB=value='', ''RB=&'', ''NotFound=ERROR'', LAST);
Lr_output_message(''Value: %s'', lr_eval_string(''{Parameter}''));
...

The output message function above prints the string component from a pointer to the LPCSTR structure ''Parameter''.
