bool not holding value?

[aewarnick]

Why do dots always print when the bool value should be set to true after one dot?

private void do3() 
		{
			if(TorF(TB1.Text))
			RTB2.Text=TB1.Text;
		}
	bool check2=false;
		public bool TorF(string str)
		{
			char[] chr = str.ToCharArray();
			
            
			foreach (char dummy in chr)
			{
				if (char.IsDigit(dummy)) return true;
				else if (dummy==.&& check2==false) {check2=true; return true;}
			}
			return false;
		}

The way that is coded, you are continuing the loop if it finds a dot and check2 is true. I guess if it finds another digit after that, itll return true. What you probably want to do is add another clause to your tests, so if it finds a dot and check2 is true, to return false.

I tried and tried till I could try no more!! So I just changed it completely:

//do3
		public void do3() 
		{
			TB1.Focus(); TB1.SelectAll();
				check2(TB1.Text);
			RTB2.Text=y;
		}
bool b=false;
string y="";
		void check2(string text)
		{
			char[] chrarray = text.ToCharArray();
            
			foreach (char x in chrarray)
			{
				if (char.IsDigit(x)) y+=x;
				else if (x==. && b==false)
				{b=true; y+=x;}
			}
		}

What exactly are you trying to do with your do3 and check2 functions? If youre trying to validate a string, you might do better to just use regular expressions. From the function names, I cant tell anything and Im too lazy to read through the code to see what you want to do

Im with you. I dont feel like figuring it out either. It works now, so I am happy. Actually I have a subscripted array problem now that should be simple but is giving me trouble. Ill post that elsewhere.
