if then endifthis. So I am hoping that I can get a lot of correspondece confirming my belief. Here it is: I believe the following: (1)If a language has an "endif", then every "if" statement requires an endif, and (2) every "endif" goes with the last "if". For example, If ..... if endif should not compile because there must be two "endif"s and the last "endif" goes with the last "if". The actual nested if statement is far more complex, and it is just being used in a presentation that is not being compiled (psuedo code). Finally, were can I find this? I don't care the language, although some version of Basic would be best since that is what my friend understands. Thanks for helping lawjake wrote:

If someCondition Then DoSomething() There is no endif here.

What
I need the answer to is if the syntax is "if..then..else...endif", can you create the code that I described above which uses and endif. Or, is there code that is "if...then...else...[endif]. Here is the exact logic that I want to know if it is correct (the indentations are the actual author's: If HoursWorked < NormalMaxHours, If HoursWorked > 0. Then Display PartTimeHoursMessage End If Else If HoursWorked = 0, Then display NoHoursMessage Else If HoursWorked > NormalMaxHours, Then display OvertimeMessage Else Display RegularTimeMessage End if I believe that the final endif goes with the last if?

30 years, somethings I know, but don't know where the documentation is anymore. I have not had to look this up in almost 30 years and did not have any books with the actual syntax. So I appreciate your help. Of course, I would have betting things to do than mock my job. Thanks again.

This sort of thing
wouldn't compile. Honestly, I'm not sure what you are asking. The way VB.NET syntax is structure, there is never really a question as to what statements are part of what 'if' or 'else'. Especially if you indent properly, which visual studio does for you. If you have the following example, it should be really obvious which statements will get executed when: If something Then If otherCondition Then CallMethod() End If ElseIf x Then DoSomething() ElseIf y Then DoSomethingElse() ElseIf z Then DoAnotherThing() End If Show quoteHide quote "lawjake" <lawj***@discussions.microsoft.com> wrote in message news:0A89605A-1891-405A-9A0A-A4D37BDCCD10@microsoft.com... >I understand that the syntax can be "if ...then", or "if..then...else". >What > I need the answer to is if the syntax is "if..then..else...endif", can you > create the code that I described above which uses and endif.

If every you're in doubt, expand every instance of If .. End If /in full/ with associated indentation. I /think/ this is something close to what you want: If HoursWorked < NormalMaxHours Then If HoursWorked > 0 Then Display PartTimeHoursMessage End If ElseIf HoursWorked = 0 Then Display NoHoursMessage ElseIf HoursWorked > NormalMaxHours Then Display OvertimeMessage Else Display RegularTimeMessage End If HTH, Phill W. lawjake wrote:

If the language has an "ElseIf" construct, as most languages do, then you may have several ElseIf's which are part of the original If, and all will be closed by a single EndIf: If Condition Then Statements ElseIf Condition Then Statements Else Statements End If On the other side, if there's no "ElseIf" construct, or the If is stated as a new statement, then yes, each if will need its own EndIf, and each EndIf will close the most recent unclosed If: If Condition1 Then StateMent Else If Condition2 Then Statement Else If Condition3 Then Statement End If 'Condition3 End If 'Condition2 End If 'Condition1 Now, notice that a language, which is the case of VB, may allow single line If's, and then you may have: If Condition Then If Condition Then Statement End If where the EndIf closes the first If. Regards, Branco. The confusion comes from C. In C, the following is perfectly valid:
if (condition1) { block1 } else if (condition2) { block 2 } else { elseblock } Note the elseif is actually two words - else and then if. There is only a single closing brace for the overall if statement. In VB this would be if condition1 then block1 elseif condition2 then block2 else elseblock end if In variants of Basic without elseif (VMS BASIC for example), this would be if condition1 then block1 else if condition2 then block2 else elseblock end if end if Note the two endifs at the end of the if statement.

If ConditionA Then DoSomething Else If ConditionB Then DoSomethingElse Else If ConditionC Then DoSomethingElseDifferent End If End If End If AND: If ConditionA Then DoSomething ElseIf ConditionB Then DoSomethingElse ElseIf ConditionC Then DoSomethingElseDifferent End If ElseIf as opposed to Else makes the structure simpler, but is more restrictive on what you can do in the general Else condition path.
