How to check if a character is from keyboard in MFC
-
Hi, dear all, I need to read a component's description from a libary. but sometimes there are some garbage values at the end of descrtion string tail, I want to remove them. So after get the description, I want to check character one by one, if the character is not a character input from keyboard, I will remove them. But how can I do it? thanks!

- What type of the string is used ? - Is the garbage offset allways the same ? - Does the get-methode return the length of its answer as well ? :)
They sought it with thimbles, they sought it with care; They pursued it with forks and hope; They threatened its life with a railway-share; They charmed it with smiles and soap. :)

[isalnum() ] does the job.

Probably not. I think a "description" of an item would include some punctuation and spaces. Peter

Then
is_from_keyboard()below is better suited. It includes punctuation , spaces etc.#include
using namespace std;int is_from_keyboard(int ch)
{if ( ch>31 && ch<128) return 1; else return -1;}
int main()
{
char ch='z';if (is_from_keyboard(ch))
cout<<"The ASCII character -> "< "< -
