reading specific text from a .txt file.

[Guest_imported]

hey,

i hope you can understand this.

I was just curious if it is possible to take a .txt document and pick out specific words or phrases

example.

//the text is

hello people, i are stupid
you is not stupid
i am happy
cows are funny
i have 1st grade education.

i want to be able to type in "cows" and get "cows are funny"
to print out. or i imput "people" and get "people, i are stupid"

i might be going about this all wrong, but i would appreciate it if you could give me a hand.

thanks much in advance...

Hi

Assume a dialog box with the following controls:
CEdit Id = IDC_TEXT (Multi-Line)
CEdit Id = IDC_TYPE where you type in
CStatic Id = IDC_LINE_FOUND where the line found is displayed

Fill the Multi-Line Edit box with the content of the file.

Use the following code to get the word type in:

CString str;
CString strLine;
char szBuffer[200];

if ( !GetDlgItemText( IDC_TYPE, str))
return;

The word you are looking for is in the variable str.

Use the following code to get the line that contains the word stored in str:

CEdit* pEdit = ( CEdit*) GetDlgItem( IDC_TEXT);

int nLineCount = pEdit->GetLineCount();

for ( int nLine = 0; nLine < nLineCount; nLine++)
{
memset( szBuffer, '\0', 200);

pEdit->GetLine( nLine, szBuffer, 200);

if ( strstr( szBuffer, str) != NULL)
SetDlgItemText( IDC_LINE_FOUND, szBuffer);
}

Note that this code does not try to verify if there is several lines with the word you type in. This is an additional work left to do ...
