SEARCH&REPLACE in a textBox

Hello.
I want to make replace & search functions in my text editor. Thanks to the
kind people here at the newsgroup, I was able to make the [REPLACE ALL]
function.
But I was not able to understand how to REPLACE the next word (the nearest
word from the cursor; not REPLACE ALL, but replace only one word) and SEARCH
the next word.
COuld some one help me? Thanks in advance.

Use the position of the cursor in the text string and find the first occurrence of the search word after that index:

String theText, searchWord, replaceWord;
int cursorPos;

// TODO:
// set the values for each variable above

int foundPos = theText.IndexOf (searchWord, cursorPos);

if (foundPos != -1) {
// if the word was found, copy the preceding text,
// sub the word and copy the trailing text

theText = theText.Substri ng(0, foundPos) + replaceWord +
theText.Substri ng(foundPos + searchWord.Leng th);
}
I hope this helps,
-JG

Hello I want a search & replace text in source code for several files in several directories. It would seem that both Dreamweaver MX 6 and GoLive 6 offer this feature but not for .aspx file types. Is there a hack that sets the configuration files for one of these programs and fools the program into allowing the global search and replace?

Hello! I am looking for a way to do a search&replace in ASCII-Files by a vb.net 2005 programm. Of coarse I can open the files, loop to every line, make a replace, and save the line. But I wonder if there is a better and faster way to do it. To make it clear: The search&replace must be done within a programm not in the Framework or editor.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
