string concat

united18

Hi, I am facing a strange problem in this. http://www.codeproject.com/vb/net/vbmp3header.asp When i try to trap the value of artist and title as: dim artist as string artist = objMP3V1.Frame(MP3ID3v1.FrameTypes.Artist) dim title as string title = objMP3V1.Frame(MP3ID3v1.FrameTypes.title) dim new Name as string newName = artist + title The variable 'newName' does not contain the values of both title and artist. It only contains of artist whereas individually i am able to see the values of artist (msgbox(artist)) and title (msgbox(title)). Pls reply within half hour.......

You're joking right? This is an all-volunteer effort forum. Not a tech support line. If you want immediate help, call Microsoft. Don't forget your credit card. But, as to your problem, string concatenation is done using:

newName = artist **&** " - " **&** title

This line: dim new Name as string is not even possible to compile. So, you are not showing us the code that you are using. How much does the real code differ from what you showed? (Sorry if this sounds picky, but I have wasted a lot of time looking for errors that doesn't exist in code that people doesn't even use.) --- b { font-weight: normal; }

sorry actually i wrote dim newName as string it was just a typing mistake here. in the program i wrote 'newName' only and not 'new name'

I tried this also, then also it is not concatenating. Both ways i do not get a compilation error, but only one value is stored in 'newName'

dim artist as string
artist = objMP3V1.Frame(MP3ID3v1.FrameTypes.Artist)
dim title as string
title = objMP3V1.Frame(MP3ID3v1.FrameTypes.Title)
dim newName as string
newName = artist + title

If this is indeed the code your using, then the only possibility is that the call to objMP3V1.Frame(MP3ID3v1.FrameTypes.Title) returned an empty string. Try copying and psting your code next time, not just typing what you think you used. We've all tried to chase down bugs in code that wasn't actually being used around here and it wastes a lot of time.

yes.... u r right. 1) i will copy the code rather than typing it here. 2) objMP3V1.Frame(MP3ID3v1.FrameTypes.Title) .This code return the value of title and similarly objMP3V1.Frame(MP3ID3v1.FrameTypes.Artist) returns the value of Artist. But when i try to concat by either i) artist + title or ii) artist & title ---- it returns only artist's value. But this problem was solved when i created 3 label fields :- label1, label2, label3. what i did was:- label1.text=objMP3V1.Frame(MP3ID3v1.FrameTypes.Title) label2.text=objMP3V1.Frame(MP3ID3v1.FrameTypes.Title) label3.text=label1.text + "-" + label2.text With this code it was concatening. But in this case also if i make these 3 label fields invisible ('label1.visible=false') then it doesn't concatenate again. So i have to always set the visible property to true of these 3 labels. This is quite strange though. Anyways thanks a lot for your help. Regards

WHAT???? This is REALLY strange. Since the .Text property of a Label only accepts a String, I have no idea what's going wrong. Perhaps a bad string comming from the library you're using? You might want to check with the people that wrote the library for any issues. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

i know this sounds strange, even u can check like this when u get time and if possible clarify me if u think i am making a mistake. Whatever, atleast this way (labels) it is working. btw the class i was using for fetching id3 tags from mp3 files is : http://www.codeproject.com/vb/net/vbmp3header.asp
