VC60, Win98, MFC I have been building a release build of my project for a year and the size of my release exe has always been around 8Meg. Suddenly my exe Release build compiles an exe file to the whapping size of 41Meg. Is there something obvious that I am missing?

Just to document: I was not setting the mask correctly. I had just set the mask to TVIF_TEXT and had not added the TVIF_PARAM. TVINSERTSTRUCT MyInsert; MyInsert.hParent=NULL; MyInsert.hInsertAfter=NULL; MyInsert.item.mask=TVIF_TEXT|TVIF_PARAM; // <<< HERE // The mask defines what is valid !! MyInsert.item.pszText=_T("A->Root"); MyInsert.item.lParam=(LPARAM)MyDataValue; HTREEITEM TVI_MyItem = m_Tree.InsertItem(&MyInsert);

Thanks, Good idea.
