Na fang doch schon mal damit an: (liegt aber im ms-Sekunden Bereich) Problem report by location - vbforum 2 Dead variable: FSO 2 Object variable declared As New: FSO Sub vbforum.Form_Load Dead procedure 2 Dead variable: s 5 LenB is faster than = "" or <> "" 10 LenB is faster than = "" or <> "" 10 Dollar would increase performance: Left$ 11 Dollar would increase performance: Left$ 19 Dollar would increase performance: Left$ 19 Dollar would increase performance: Mid$ 37 Dollar would increase performance: Left$ Problem summary Problem Type Count Dead procedure/declaration/event Optim. 1 Dead variable/parameter Optim. 2 Dollar would increase performance Optim. 5 LenB is faster than = "" or <> "" Optim. 2 Object variable declared As New Optim. 1 Unused file Optim. 1 Type Count Optimization 12 ******************** Total 12 Problems/logical code line 0,26 Filter: <Optimizations> Problem descriptions Dead procedure/declaration/event A procedure, a DLL declaration or an Event declaration is not used by the project. It is not called by the code nor executed by any other means. You may remove it if you are sure you won't need it later. The removal doesn't affect the functionality of your program. - Event declarations are reported dead only if they are not raised nor handled. See the problem Event not raised for events that would be handled but that are not fired. Optimization. Severity: Warning. Dead variable/parameter A variable or constant is not used. You may remove it if you are sure you won't need it later. The removal doesn't affect the functionality of your program. Optimization. Severity: Warning. Dollar would increase performance Adding $ at the end of a function would increase the speed of execution. Certain functions, like Left, Mid and Right return a Variant that contains a String. The corresponding functions Left$, Mid$ and Right$ return a String. Using the String version makes your program run faster. Applies to VB 3-6. Optimization. Severity: Info. LenB is faster than = "" or <> "" To check if a string is empty or not, it's quickest to use the LenB function. To test for an empty string, use LenB(str)=0. To test for a non-empty string, use LenB(str)<>0. LenB is available in VB 4-6. In VB3 and VB.NET, use the Len function for the same effect. Optimization. Severity: Warning. Object variable declared As New In VB Classic, declaring an object variable As New creates an auto-instantiating variable. Each time you read the contents of the variable, VB first checks if the variable contains an object, and creates one if not. This adds overhead, thus slowing your program down. To achieve better performance, remove the word New from the declaration, and instantiate your variable (Set x = New Class) before it is used. It makes sense to test with 'If x Is Nothing Then' before accessing the variable, to avoid the run-time error 'Object variable not set'. In addition, VB.NET has different semantics for As New. Applies to VB 3-6. Optimization. Severity: Warning. Project Analyzer 7.1.02 (14.02.2006)
