DOCUMENT:Q129897 11-JAN-2001 [vbwin] TITLE :PRB: Procedure too Large Error When Compiling in VB 4.0 PRODUCT :Microsoft Visual Basic for Windows PROD/VER:WINDOWS:4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Standard Edition, 32-bit, for Windows, version 4.0 - Microsoft Visual Basic Professional Edition, 16-bit, for Windows, version 4.0 - Microsoft Visual Basic Professional Edition, 32-bit, for Windows, version 4.0 - Microsoft Visual Basic Enterprise Edition, 16-bit, for Windows, version 4.0 - Microsoft Visual Basic Enterprise Edition, 32-bit, for Windows, version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Some procedures that compile in Visual Basic version 3.0 generate the following compile-time error message in Visual Basic version 4.0: Procedure too large CAUSE ===== The maximum size of the internal code for an individual procedure in Visual Basic version 3.0 is 64K bytes. Microsoft Visual Basic version 4.0 for Windows uses Microsoft Visual Basic for Applications, which generates more generic internal code than does Microsoft Visual Basic version 3.0. This generic code allows for compatibility with a wider range of processors. This makes the internal code larger, so it can cause very large procedures to exceed the 64K limit and fail to compile. WORKAROUND ========== Split the large procedure into two or more smaller procedures. STATUS ====== This behavior is by design.
