The information in this article applies to:
  • Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 16-bit and 32-bit, for Windows, version 4.0

SUMMARY

The whitepaper covers many aspects of optimizing Visual Basic 4.0 programs. This includes, but is not limited to, the following topics:

  • Optimization philosophy: where to start and where to stop
  • Determining what aspect(s) to best optimize
  • Optimizing actual speed: - use correct data types - cache properties in variables - use of correct looping constructs
  • Optimizing display speed - proper settings of graphics related properties - use of controls vs. code when appropriate
  • Optimizing apparent speed - performing work behind the scenes - doing heavy computational tasks when time is available - how to speed up load times, both real and perceived
  • Keeping application memory size small - using correct data types - reclaiming unused space - cutting back on graphics
  • Segmenting applications with OLE - ability to load and unload on demand - 16-bit code can be separated from 32-bit code - using remote OLE servers to distribute load
  • Optimizing OLE - early binding vs. late binding - using proper language constructs - minimizing cross process calls
