Are you getting a panic code? Also are you working in the emulator on on the device?

Type of listbox is...

iLogListBox = new (ELeave) CAknSingleGraphicStyleListBox;

... so you have to include a graphic index for each line in your listbox.

eg

for (TInt i=0; i<array->Count(); i++)
{
TFileName listitem(_L("0\t")); // the 0 indicates the 1st graphic in your list as set up in SetupListIconsL()
listitem += (*array)[i]; // add the actual text you want to display
listBoxItems->AppendL(listitem);
}
iLogListBox->HandleItemAdditionL();

And a note about naming conventions:

ReadDataFromFile()

should read

ReadDataFromFileL()

... as it is possible for this function to leave

many many thanks for help...
it works fine now :-)

I really didnt understand much what these 2 lines do????:

TFileName listitem(_L("0\t"));
listitem += (*array)[i];
