Hello,

With the help of a forum member from EE whom I am extremely grateful to, my MP3 program within Delphi is complete except when a User enters new details for an ID3 Tag and then clicks Ok the program displays the following error message:

'Access Violation at address 00479BCA in module 'Project1.exe'.  Read of address 00000000'

What does this mean and how can it be resolved?.

Thanks awfully for looking and I wish you all the best and I apologise for the low point amount, I'm sorry.

Thank you.

Hi  ryujingt3,

I've been waiting for you to surface again. I was cleaning up old test folders and deleted your code by mistake. Would you send me the latest code i sen tyou, and i will take a look right now.

if TempString is a string, you may want to do this

for index := 1 to length(Tempstring) do

just in case it was missed :)

Hi robn, he then adds each char to a Array, i've seen the code,

where he does


 for index := 0 to length(Tempstring)-1  do
 
 MyArray[Index]:= tmpString[Index + 1];

Hi Shane,

Thanks very much for that, can you explain what I was doing wrong?.  Also, is it possible for the program to show the newly entered data instantly without requiring a restart as it currently does?.

Thanks.

Right, a quick update, the error has disappeared thanks to the help given from Shane, strangely though my version still refuses to update the newly entered data instantly and I do not know why even though you have told me that your version does this.

I have emailed you about this and look forward to your response and thank you for all your invaluable help.

Thanks.
