Possible To Use Select Case To Chose Between Webpage.elements?
Mar 2, 2011
I'm creating an application that will be visiting several different sites.Each site will have the same elements but not necessarily in the same order.On a previous post I was told to use the Select Case to choose between the choices.Can Select Case be used to choose between Webpage elements?Let's say that on one site the first web page element is choose button A but on site two it will choose button B.
Dim makeachoice As String
makeachoice = webbrowser1.element button A

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?
i have a program using a select case to convert letters to special charaters. My question is how can I get the code to read upper and lower case letters without having to put the upper case letters in my select case statement. Example: Part of my code is
ive got a form containing treeview on the left docked, and two panels one over the other (just as for practice), so i am using treeview to select one from the other the code contains the Case select,

The problem is , both panels are not visible, when i select the first node the firstpanel is visible then i select the second node both panels are not visible, i return to the first node the first panel is visible.

I want to make an application that takes values & innerhtml from some elements on a webpage i made. For that i added a webbrowser to the project, and pointed it to navigate to my localhost server where i have some pages. However when i use the document.getelementbyid i don't get nothing on my richtextbox, and i don't know why, i use this function lot in javascript & i think its quite similar, so i don't know why it doesn't work , here is the code i use.
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.
I have a macro that uses "If Then" to choose what macro to run based on the ActiveCell. I would like to use the Select Case method instead. How would I change this code?
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range) Application.DisplayAlerts = False Application.ScreenUpdating = False
It would give me 5 instead 4 results, since <title>My Channel</title> is considered one of the item under channel. I'm just wondering if there is anyway to loop through only the 4 item elements.
Question is, I basically wrote a Rock Paper Scissors game in VB.NET using If statements and wondered how exactly I would try and work this into a Select Case instead.Professor was pretty awful at teaching things and didn't let us know until today that it had to be Select Case(its due tomorrow
I am convertng vb.net to c# 2010 as my job, and none of the automatic tools I have can succeed completely. In special example, this case:
[Code]...
I am mostly java developer before this, so not great with c# and none with vb.net. I do not understand the "oaaaa to" part and this part is not converting. Can you please point me to right place to find the c# version of this?
I have an if-elseif-then setup as below: Private Sub CommandButton1_Click() If OptionButton1.Value = True Then getdate Unload glpmenu [Code] ..... I would like to change to Select Case.
I am using visual basic in VS 2008 and trying to learn how to assign a value to a word in a combo box using case select, this is my first attempt at programing and i just can't work out what to do next. So far i have two combo boxes a label and a button, i want the word, first to = 11, second = 9, third =7, fourth = 5. All it is doing at the moment is adding the list index value and displaying that total in the label. I want it to display for eg: if (first=11) and (second=9) are selected a total of 20 in the label,and so on for what ever combination is selected.
I have assigned nodes in my treeview keys depending on what they are to do with and now i would like to use a select case to choose the right calculation depending on which node is selected.i have tried selecting the key like this:
Select Case tvwFCOM.Nodes.IndexOfKey(tvwFCOM.SelectedNode.Text) Case Is = "assi06" Call MinimumSpeeds()
but option strict on dissalows conversion from string to integer. there are more cases, but i have only shown one here. How can i code so that the key is selected from the selected node?
I had to change the given code from If Then to Select Case, and this is what I came up with. But when I run the program, it does not work and gives me zeroes instead of the correct information.
Public Class MovieInfo Private wkndBox, screens As Integer Private title As String
I just replaced a different segment of code with the select case statement and it works fine. However I don't understand what the dim is for after you do "Select case [variable name here]"
I currently just dimmed a value as nothing. I didn't specify any data type for my variable I'm using for this case statement. But it works.[code]...
I am in my programming class and we had a small program to make that would check to see if an value that was entered is a integer and convert it to a Roman numeral. I know how to properly do it by putting the TryParse into the If...Then statement. What I am trying to do is to not use an If...Then statement and go just by a Case Selection statement. If it is not possible then that is cool with me, I am just trying to think outside the box. Here is what i have done with it: [code]....
When you do say "Case 1" it says it needs to be "Case CBool(1)." Using either "Case CBool(1)" or "Case 1 = 1" provides the same result .However the code shows no errors it doesn't do the conversion, it always displays the label's value as "I"
I have a question regarding a null value which I am not supposed to get in VB. Here is my code.
Public Class SelectDemo Private Sub lstData_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstData.SelectedIndexChanged
Select Case currentNodeName Case "string1","string2","string3","stringEtc" Case Else
[Code]....
The above is a code snippet... of course I've already made my declarations earlier in the code. My issue is I get the error " 'Select Case' must end with a matching 'End Select'." It looks to me like VB is not liking my If statement with the "Next For" in the middle. I'm sure this is a basic syntax issue.
