VS 2010 - Multiple Conditions For Select Case
Jun 26, 2010
I'm programming a utility for a game, and at the moment I am adding chat commands for it. They use the Select Case type, but I want to be able to use multiple conditions for 1 case.
Current
Case "/lame"
If sParameter = "announce" Then
AnnounceMsg("^1No Laming
^7Laming consists of
^5* ^7Attacking someone with
^5- ^7Weapon Down
^5- ^7Chatbubble Up")
[Code] .....
I get an error:
Conversion from string "/lame" to type 'Long' is not valid.

I have an app that adds ammount to gether and i am trrying to do some error checking. This is the code i Have so far
CODE:
I would like to turn this into a select case so that it calls all the code need to check before running. I have tried to do it my self but has been ages since i coded and even then it was in VB6. I know there is a way to do the case in a module and then call it into the form where i need it. i have 3 radio buttons that if they are not selected it pops up a message to say so.

When my form loads it adds some handles (using AddHandler) to a sub (showStatus). What this sub does is checks which control activated the sub (using sender.Equals) and displays text in the status label (status) accordingly.For this I use an If...Then statement for each possibility. There are many possibilities and my code get cluttered. Is there a way to do the same thing with a Select...Case statement. I tried: Select Case sender Case tbOne : status.Text = "blahblahblahblahblahblah" End Selectwhere: tbOne is a textbox, status is a StatusLabelIt gives me an error though, saying "Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.TextBox'."Any ideas on how I can get this to work with a select case statement?

How would I perform this SQL query
Select Distinct s.*
from #ScopeIDs x
Join Scopes s on s.ScopeID=x.ScopeID or x.ScopeID is null
in LINQ to SQL? (This query would return all Scopes whose ScopeID is present in #ScopeIDs, unless one of the entries in #ScopeIDs is null, in which case it returns all Scopes).
A "literal" translation doesn't work, since LINQ doesn't support joining with multiple conditions - code along these lines ...
From x in ScopeIDs
Join s in Scopes on s.ScopeID equals x.ScopeID or x.ScopeID equals nothing
Distinct Select s
... doesn't compile.

I currently have an If...Then statement that checks if all fields of a form have been filled before saving the info in a file. I'd like to be able to tell which field has not been filled to give the user a dynamic message (at the moment, it only tells them that the checklist is not completed ) :
If (txtNoDemande.TextLength = 8 _
Or txtNoDemande.TextLength = 13 _
And txtDateLoad.TextLength <> 0 _

Is there a way to determine which of these conditions is false without having to do a seperate If statement for each ?

I have the following:
myFilteredContractors = (From c In myFilteredContractors
Join cc In myConClasses On c.ContractorId Equals cc.ContractorId
Where inClassifications.Contains(cc.ClassificationId)[code].....
This is properly ordering this list of contractors by the number of classifications that they have.I also want to order them by whether or not they have a field set (CompanyOverview), which if is an empty string should be below those contractors who have set their CompanyOverview. Also, after the CompanyOverview is ordered I want to order by Registration Date.So it should order by:
Number of Classifications
Whether Overview has been set (c.CompanyOverview)
Registration Date (c.AppliedDate)
Is it possible to all of this in LINQ?

I am trying to write a Function which will return a data table, filled with a data from a database.
The Function will accept 6 diffrenet parameters as Optional. Each one of them will be an additional condition to be added to a where clause, if it`s provided when the function is beeing called.
Is there any method in .NET to simply add a new condition to the where clause?

I have a form that contains multiple conditional or if statements on several defferent for controls.
Example: Radio Buttons, TextBoxes and CheckBoxes.
I am intending to create an order form(demo) where the user can select multiple products.
I have a default order number that changes by one everytime an order is successful.
An order is only successful if all the information on the form is entered correctly.
My question is where do I insert the code for the order number?
Basically for the order number I have a counter that count by increment of one if an order is successful.
Meaning when the user hit place order, and all the infromation is right, then the order numer goes to 1 from zero.
Where do I add the condition for the order number since all the fields must first be completed.
Do I have to create a whole line of if else statements?

I built a form that has 3 Listview objects. Each Listview contains items, the user is to select an item from a Listview and click a button that moves the item "up" or "down" to an adjacent Listview.I am having a difficult time "knowing" which Listview item has been selected. The problem arises once a user has clicked items from different Listviews. Even though, visually, only one item is selected in one Listview, the program still detects a selection from other Listviews.

I'm working on a routine that requires a significant amount of nested and daisy-chained logic. Using If-Then-Else, each logic construct would run 8-15 lines of code (quite readable) while using Select Case each construct doubles that (even with significant commentation, it gets less and less readable with each new Case).
I've read many times in this forum how Select Case is leaps and bounds ahead of If-Then-Else in runtime performance, although I can't recall any discussion of the underlying process(es) that make it so. I've also not had any luck finding good, detailed documentation on the nuts and bolts under each logic construct. What I'm working on, if the performance leap is legit, needs the performance more than the readability but if the performance is marginal then the readability is going to get the priority. how and why Select Case is supposed to process so much faster than If-Then-Else. Links to good white paper would be really nice too.
