I have tried using NI DAQ (using digital output pins) and NI VISA. i am finding it difficult to get the output.
what are the steps to be taken ?
That's a question about NI DAQ and/or NI VISA - neither of which has anything to do with ST or the STM32.
You need to go to NI for help with their tools:

I want to send some data (like an integer or a decimal number) from Labview to the STM32 Nucleo F401RE board Shruthi
As far as the STM32 is concerned, that's purely about receiving serial data - the NI stuff is irrelevant.
The STM32 neither knows nor cares what generates the data - all it sees is bytes arriving at the UART's RX pin.
You can test your STM32's UART reception just using a simple serial terminal:
