Welcome to Forums!

Some time ago I came across this sample which strikes through entire line when dblclicked.
you may reuse that technic but you will also need to find some keyword so you know where the line begins.
The following sample will delete single (very first) occurence of say lines beginning with "user2:"

Private Sub Command1_Click()
Dim StarPoint As Long

    startpoint = InStr(1, RichTextBox1.Text, "user2:")
    If startpoint > 0 Then
        RichTextBox1.SelStart = startpoint
        DeleteLine RichTextBox1    '<<< I purposely renamed original procedure
    End If

End Sub

In the StrikeLine procedure (available through that link) you will need to replace last line:

rch.SelStrikeThru = Not rch.SelStrikeThru

with this:

rch.SelText = ""


Also, to get rid of all occurences you will need to loop while InStr returns result greater than zero.

Here's an example that removes the second line that you can easily modify to remove any line that you want.

EDIT:

NEVER MIND. JCIS's works just fine and doesnt remove the color,
how ever. martinliss's works great except it does remove the color,

thanks for the help guys ;]

The code that I had posted here has some copyrights. So, I am removing it, as instructed by Rhino in the below post.
Sorry for posting that copyprotected code. I had posted it with some changes, as a solution to this thread. I was not aware that the code was copyprotected, at the time of posting.
Sorry again

Okay, I've gotta it down to the point where i can remove the exact line by number. With out loosing the color of the text that's left. a bit shorter then tha last post and some adjustments from other post.

Now Step 2, How to the Line Index by searching by "String" example;
Find = "<Username>" and figure out what it's index is..

Step 3, would be to re-insert the line that was removed, say if the user was UNIGNORED.. anyways im not to worried about that yet. ;]

@Akhilesh:

please remove all posted code - it's copyrighted; you may only provide link to original.

oh wah, its vb6, if you think about it, ALL code can be copyrighted.. most of half of anyones projects im shure some part of it has been copyrighted somewhere. weather you know about it OR not.

anyways, *bump* i searched msdn, and google last night. I came across a couple of things on msdn, well the const, and all they show u is how sendmessage works, wich i already know how it works but they don't give you a heads up on how to use the constants. :[

No, I'm afraid you have a wrong idea. Lots of public websites offer "free' code which is copyrighted in vast majority cases.
If you read disclosure statement you will find something similar to this:
"you may freely use and distribute this code in your own application however do not replicate it or post it on any website, magazine, etc..."

Don't you think that it's a fair demand from the author who spent his/her time developing that sample that will save you lots of time and frustration?
Think about it again.

[siklife1]

I've thought about it, and despite what anyones written, it's already have been done before, probley word for word. when it comes to helping others. But whining over some code 300 other people wrote exaclty the same is useless, Specially in an un-supported language.


Anyways please stay on topic before destroying my only thread with nonsence. Like i said, help will be appreciated.

The current problem is to get the Line.Index of tha text found, What can be a good alternitive to find the index line of a certain string. Thanks! ;]

Anyway, you had been provided with 3 working solutions but misteriously you failed to implement any of it.
I'm not sure what kind of help you're looking.

Sorry pal.

It's never a bad idea to open new thread if original question has been answered - keeping basically resolved thread open forever may confuse many responders.

That's true i suppose, but i didn't see why opening a new thread when the issues has to do with the same control and idea concept anyway, people how ever can become confused because this thread now has alot of useless posts.

Off to make a new thread then.
