You are adding to node cur. Cur is always 0 or 1.
You want to AddChild to the last Add node:

	cur = TreeView1->Items->Item[0];
	cur = TreeView1->Items->Add(cur,szBuffer);
	TreeView1->Items->AddChild(cur,szBuffer);

Try this code instead:

    TreeView1->Items->BeginUpdate();
    try
    {
        TreeView1->Items->Clear();

        LPTSTR lpBuf = (LPTSTR) LocalAlloc(LPTR, 0x7FFF);
        if( lpBuf )
        {
            TTreeNode *RootNode = TreeView1->Items->Add(NULL, "CDS");
            GetPrivateProfileSectionNames(lpBuf, 0x7FFF, 
TEXT("CDPLAYER.UNI"));

            LPTSTR lpTemp = lpBuf;
            TCHAR szBuffer[64];

            while( *lpTemp )
            {
                if( GetPrivateProfileString(lpTemp, TEXT("Artist"), 
TEXT("Nicht gefunden"), szBuffer, sizeof(szBuffer), TEXT("CDPLAYER.UNI")) )
                {
                    TTreeNode *ArtistNode = 
TreeView1->Items->AddChild(RootNode, szBuffer);
                    if( GetPrivateProfileString(lpTemp, TEXT("Title"), 
TEXT("Nicht gefunden"), szBuffer, sizeof(szBuffer), TEXT("CDPLAYER.UNI")) )
                        TreeView1->Items->AddChild(ArtistNode, szBuffer);
                }

                lpTemp += lstrlen(lpTemp)+1;
            }

            LocalFree(lpBuf);
            TreeView1->AlphaSort();
        }
    }
    __finally
    {
        TreeView1->Items->EndUpdate();
    }

Alternatively, since you are using the VCL anyway:

    #include <IniFiles.hpp>
    #include <memory>

    std::auto_ptr<TIniFile> Ini(new TIniFile("CDPLAYER.UNI"));

    TreeView1->Items->BeginUpdate();
    try
    {
        TreeView1->Items->Clear();


        std::auto_ptr<TStringList> Sections(new TStringList);
        Ini->ReadSections(Sections.get());

        TTreeNode *RootNode = TreeView1->Items->Add(NULL, "CDS");
        for(int i = 0; i < Sections->Count; ++i)
        {
            AnsiString tmp = Ini->ReadString(Sections->Strings[i], "Artist", 
"Nicht gefunden");
            TTreeNode *ArtistNode = TreeView1->Items->AddChild(RootNode, 
tmp);

            tmp = Ini->ReadString(Sections->Strings[i], "Title", "Nicht 
gefunden");
            TreeView1->Items->AddChild(ArtistNode, tmp);
        }

        TreeView1->AlphaSort();
    }
    __finally
    {
        TreeView1->Items->EndUpdate();
    }

Because you are calling Add() instead of AddChild() when adding each artist 
node.

Hi,
I will try this at once.

Hi,
tried this and it works fine for me. 
So this ist stage 1. 
Next stage will be the sorted output.

Thanks
