CSharp problem

[hkhellhkhell@hotmail.com]

i have an application that will take user input from a text box and
write it
to an access database. i need to make sure that if they ever enter a
single
line of text that it has at least 1 space for every 40 characters.

so before i write the info to the database i have to make sure there is
no
lines of text that are longer than 40 characters without a space, and
if
there are insert a space at the 41st character. is that as hard as it
sounds?

Hello hkhellhkhell@ho tmail.com,

use Regexp class or manually check the TextBox.TextLen gth property

longer than 40 characters without a space, and
if
there are insert a space at the 41st character. is that as hard as it
sounds?

I'm assuming that you want a space every 40 characters on a line. That
is, that you want a line of 90 non-blank characters to have spaces
inserted at 40 and at 80, not just at 40.

string rawText;
StringBuilder sb = new StringBuilder() ;
int i = 0;
int charsWithNoSpac e = 0;
while (i < rawText.Length)
{
if (charsWithNoSpa ce == 41)
{
sb.Append(' ');
charsWithNoSpac e = 0;
}
if (rawText[i] == ' ' || rawText[i] == '\n')
{
charsWithNoSpac e = 0;
}
sb.Append(rawTe xt[i]);
charsWithNoSpac e = 0;
i += 1;
}

Possible refinements: if you want _any_ whitespace character to count,
not just space and newline, you could use Char.IsWhitespa ce(rawText[i])
instead of the explicit test for blank and newline.

Re: CSharp problem

The following function will do what I believe you want. Note that I used a
parameter to specify the maximum number of characters before a space, just
in case you decide to change it from 40.

public string EnsureSpaces(st ring target, int maxChars)
{
StringBuilder result = new StringBuilder() ;
int charCount = 0;
for (int i = 0; i < target.Length; i++)
{
if (target[i] != ' ') charCount++;
else charCount = 0;
if (charCount >= maxChars) result.Append(' ');
result.Append(t arget[i]);
}
return result.ToString ();
}
