Error_1_Implicitly-typed local variables must be initialized_

Hi,
I am to programming and done the self help books.
I receive an error when running an application - Implicitly-typed local variables must be initialized
Code below.
I have also tried to declare Age as int and get the following error
Error 1 Cannot implicitly convert type 'string' to 'int'
static void Main(string[] arg)
string FirstName;
string Surname;
var Age;
Console.WriteLine("What is your first name? ");
FirstName = Console.ReadLine();
Console.WriteLine("What is your surname? ");
Surname = Console.ReadLine();
Console.WriteLine("Hello "+ FirstName + " " + Surname );
Console.WriteLine("What is your date of birth?");
Age = Console.ReadLine();
if(Age <= 35)
Console.WriteLine("No Late Joiner Penalties apply.");

Hi,
As Ezra94 said, your are in the wrong forum.
Because it's C#, I advise you to post on this forum : https://social.msdn.microsoft.com/Forums/en-US/home?forum=csharpgeneral.
Now I'm C# developper so you're problem is on the line
var Age;
because you couldn't use "var" without initializing your variable because the compiler can't determine the real type. So to correct your program change the line by :
int Age;
But for the next time, choose the good forum, thanks,

Variables must be initialized error

Getting this error when inserting the following code:
Local variables must be initialized.
The variable temp near line 3, column 5 lacks an initializer.
The CFML compiler was processing:
a script statement beginning with "var" on line 3, column 1.
a script statement beginning with "function" on line 2,
column 1.
a cfscript tag beginning on line 1, column 2.
Am I missing something?
Thank you.

Yes. You're not reading what the error message says. Because
it's telling
you exactly what you're doing wrong ;-)
> function FixedWidth (Val, Num) {
> var temp;
What are you NOT doing here?
A lot of languages allow one to declare a variable without
initialising it.
CF is not one of those languages.
PS, regarding this:
FixedWidth (Val, Num)
val is a very poor name for a variable, as it is the name of
a built-in
function. It won't error, it's just poor form.

Are all local variables indexed consecutively?

Dear All,
In JVM, each frame contains an array of variables addressed by indexing. I am wondering if all local variables must be stored consecutively in the array.
For example, is it possible for this scenario to happen:
The length of the local variable array is 10, and a compiler translates 3 local variables of type Object to be located at index 3, 5, and 8 respectively (assuming no parameters in their enclosing method)?
The reason I need to know this is because I am using ASM to transform bytecode and need to introduce my own local variables. If all local variables' indices must be consecutive, I can get the max. number of locals (3 in the above example) of the original method and give my new locals indices starting from 4, ... But if they are not consecutively indexed, I have to use other ways.
Your help is much appreciated,
-- Sunny

Therefor my other question is: does max_locals
represent the length of the local variable array, or
does it mean the number of local variables that are
actually exist in the array? Thanks again.It gives the number of local variables in the local variable array but long and double are each considered to reserve two local variables and contribute two units toward the max_locals value.

Local variable doubt

Hello every1,
i m new to java...i wanted to know:
class A{

It's a myth that exactly Java newbies would benefit from starting out with a rudimentary text editor typing shell commands. Nobody in their right mind would suggest that to a .NET newbie. Is Visual Studio really so much better than Eclipse or Netbeans?
Using a good IDE will allow newbies to concentrate on the fun part of Java namely the actual programming right from the start.
There are two extremely persistent myths plaguing Java. One is that Java is slow. The other is that Java must be taught using ancient development tools.Its not a myth, its more personal preference. I think it is good to at least start out using a text editor and command line so you are forced to spot your own mistakes and debug your code with your own eyes instead of having an IDE highlight your errors for you. This is just to start out, I think it help build your debugging ability. Now whether it take you 1 week or 1 year to move into using and IDE is up to you, but its good to at least get the experience of coding without one for a bit at the beginning and just focus on learning the language.
Just my opinion and again it really is personal preference. We could go on and on about it I'm sure. Probably a topic for its own thread.
Back on topic, I do see the code and illustration on page 259. flounder covered the explanation well though. Just to reiterate, when calling the go method:
public void doStuff()
boolean b = true;
go(4);
public void go(int x)
}when go() is being called, only the value 4 is being passed, the variables remain inside the doStuff() method. the value is copied, if you will, to the variable "x" which is a local variable inside the go() method. once the go() method has been called, the variables inside of the doStuff() method are out of scope because that method is not currently on the top of the stack and is not currently running, but the value of one of the local variables was copied to the local variable "x" in the go() method as that method was put on the top of the stack. so now the variable x is in scope with the copy of the value from the doStuff() method

To make things clear, here are two small examples that show how nasty locals and value properties can be to the naive programmer.
- Open the diagram of the race condition.vi before running it and try to predict what will be the values of the two counters after the third run.
- Use the Compare Locals Properties and Wires.vi to find out how slow locals and value properties can be (times 1000+).
This being demonstrated, I must add that I use globals and value properties quite often, because they are often very convenient

Inserting in the UUT_Results table a value that we read from our data base from a local variable

We would like to include in the UUT_Results table a value that we read from our data base into a local variable during the execution of our sequence file. We found that by modifying the configure database options we were able to add a column for this variable, but the local variable was not available to be placed into an expression for that column from the local variables or parameters. Is it possible to do this, and if so, how? Station Globals were available to be included in the expression, however the sequence file may be executed on more than one system which makes the Global unavailable on systems other than the one where the sequence file originated.

You can use the TestStand API to programmatically create global variables at runtime, thus ensuring their existence. For example, you could call Engine.Globals.SetValString("GlobalStringVariableName", PropOption_InsertIfMissing, "variable value")
Of course, if you need to test multiple UUTs in parallel, a single global is not sufficient. In that case you might consider adding the field you need to the UUT datatype in the process model. You could then access the field in your sequence via RunState.Root.Locals.UUT.YourNewField = YourNewValue.
If you also want your sequence to run without using a process model, you must check for the existence of the UUT before accessing it. You could use the expression function: PropertyExists("RunState.Root.Locals.UUT.YourNewFi
eld")

Can't see 'Local Variables' while debugging in Sun Studio 11

I am debugging a C/C++ application built with Sun Studio 11 running on Solaris 10. I load the application as always, set a breakpoint and run. The debugger stops at the assigned breakpoint as expected.
The issue is that at this point there are no local variables displayed in the local variables pane.
I have tried restarting SS11, rebuilding, etc...
This is the first time I have seen this happen.
Does anyone else have an idea what is wrong?

Does adding a particular variable to Watch view help? (it can be done by typing "display <variable>" in dbx command line).
You can also try erasing (or better moving to a temporary location) all Sun Studio settings like this:
mv -f ~/.sunstudio /tmpand start debugging session again.

Are the read and write operations atomic for an array in a local variable.

Hi,
I would like to know when you access an array in a local variable, is it an atomic operation?
Thanks,
Mat

Thanks for the comments. I agree with you. However, I my case, race conditions and synchronization are not issues. Therefore, the only thing that matters to me is that the write and read operation of the array must be atomic. I know that I can implement that with a LV2 style global but I want to avoid it if possible.
If writing and reading to an array are atomic operations then I can simply use local or global variables.
All I need to know is: Is reading or writing an array in a local variable an atomic operation?
Thanks,
Mat

How do i declare a user defined table type sproc parameter as a local variable?

Why are you asking how to be an awful SQL programmer?? Your whole approach to SQL is wrong.
We have a DATE data type so your insanely long NVARCHAR(50) of Chinese Unicode strings is absurd. Perhaps you can post your careful research on this? Can you post one example of a fifty character date in any language?
The use of the "sp_" prefix has special meaning in T-SQL dialect. Good SQL programmers do not use CREATE TYPE for anything. It is dialect and useless. It is how OO programmers fake it in SQL.
The design flaw of using a "tbl-" prefix on town names is called "tibbling" and we laugh at it.
There are no lists in RDBMS; all values are shown as scalar values. First Normal Form (1NF)? This looks like a set, which would have a name.
In any -- repeat any -- declarative programming language, we do not use local variables. You have done nothing right at any level. You need more help than forum kludges.

Make list of names in local variable list appear in alphabetical order?

When you select a variable name from the drop down list of a local variable the list appears to be in chronological order. Is there any to make this list appear in alphabetical order?
George

Hi George:
You said that local variables list appears in chronological order, but you wanted to appear in alphabetic order.
You just need to set apropiate names and then use SetTabbingOrder
You can use SetTabbingOrder to order all controls and indicators of your front panel, treating every control you see in the block diagram as one
(A cluster is one of the controls you can order, but the elements inside the cluster must be ordered with ReorderControlsInCluster right-clicking the cluster)
Returning. To SetTabbingOrder you have to click on VI's EDIT menu and select Set Tabbing Order.
The front panel will turn it's color to somethin darker, and every control will be shown with a number.
That number is it's tabbing index.
At the beginning you see a 0 in the top, that means that if you click in a control, that control will become number 0, and then the number it the top will pass to be 1, so you can select the next control in order.
If your first 23 elements are ordered, you don't need to click all 23, you can just set the top number to 23 and continue ordering.
When you reorder an element, all elements before that remain the same, and the rest are added by one.
When you are don, click on OK, or discard changes with x
This SetTabbingOrder you can do with elements in your front panel, can be done with elements into a cluster and elements into a Tab Control. Only change de name (in clusters is "Reorder controls in cluster" and in Tabs is "Reorder controls in page"), but they work the same
You might be interested in reordering in groups than reordering alphabetically?
Hope it helps,
Aitortxo.

No difference between using a local variable and a notifier in timed parallel loops?

The example code "Pass Data With Notifiers.vi" that came with LV 7.1 illustrates using notifiers with parallel loops. Just looking at two of the loops, the one that generates the sine wave and the one for "User 1", you can change the timing of the two loops and you can change the condition of the "Ignore Previous" status on the "Wait on Notification". I have a special case of this to consider, where I'm wondering if there's any reason not to use a local variable instead of the notifier:
Set the delay on the generator portion (which contains the Send Notification) to something very short, say 5 ms. Set the delay on the User 1 (which contains the Wait on Notification) to something relatively longer, say 200 ms. Set the Wait on Notification to False. Now you have a situation where the User 1 loop action is contingent only upon the loop delay time, since each time the loop timer runs the loop there will always be a value in the notifier. In this case it seems to behave just like the case where you update a local variable in the fast loop and read it in the slow one.
Is my understanding correct? Would there be a performance difference between the two methods? What do you prefer in this situation and why?
Thanks,
Hosehead

Hi H.,
I think your idea is to write to a Global Variable in the data-producer VI, and read it in the data-consumer VI(?)
One reason this might be less efficient than using Notifiers is if you want to graph every new value in the "consumer" - or make sure the value read in the consumer has changed at least once since the last loop.
> since each time the [consumer] loop timer runs the loop there will always be a value in the notifier...
> Would there be a performance difference between the two methods?
If you don't use the Notification "event" to synchronize the producer and consumer, then to be sure the consumer gets a new vaue, you've made the producer loop faster - every 5 ms - a waste of cpu-cycles. More often the situation is reversed, that is, there's a consumer that needs to see every single new value, and (without events) the consumer must loop faster than the producer (to catch every new value) - this is called polling and it wastes cpu-cycles.
Just about anytime one's tempted to make a loop execute "fast" to check on some value (or to make sure there's a fresh value,) there's an opportunity to improve performance through synchronization with events (including notifiers, queues, occurrances, semaphores, and rendezvous')

Memory (RAM) model in Flex or ActionScript for local variables in a method

I have a method in AS3 to handle certain event generated from some Components in <mx:Repeater>. Two different Components can fire the same event
at the same time so the same method must handle the two events together. My question is if the two calls on the same event handler method will step on each other. The event handler method only uses the local variables.
In Java, the local variables of a method for the two callers are in two different memory (RAM) addresses. So they will not step on each other. Not sure about
Flex/ActionScript.

Actionscript runs in a single thread. One of the events will get fully
processed before the other.

Having Trouble Copy and Pasteing Local Variable in LabVIEW 2010

I am Having Trouble Copy and Pasteing Local Variable in LabVIEW 2010 in s subVI.
I have a VI that has a Local Variable called "Node Addr". I can select it OK, and it appears to Copy OK, But when I go to paste it, nothing appears. It doesn't matter if I use Cntrl-C Cntrl-V or the Copy and Paste from the Edit menu, I get the same results. I tried many times and got the same results. I made sure that I had click a paste location. I can insert the Local Variable if I use the Data Communication panel.
On one of the Paste, I got an error in the error list that said that a Local Variable was not connected to anything. When I clicked on the error, it took me to an insible item in the lower right corner of the block diagram that had nothing but a select box around it. I couldn't select the invisible item, but I could delete it.
Why does the copy and paste of this local variable not work?
Why does the paste cause the insertion of an invisible item?

My VI is fairly complicated. In several places in the VI, I am either reading or writing to this variable which is an numeric Indicator on the Front Panel. Using local variables seems to be the best way to handle this situation rather that using wiring all over the VI. Since the VI is mainly a State Machine and there are only 2 Writes to the local variable, I am not afraid of race conditions in this case. NO!! While you may think that using Locals is your solution to wiring, it is not! The fact that you are writing and reading, most likely from several places, will most definitely contribute to a race condition. Depending on your implemetation, you should ALWAYS use wires. The wires are the variable. If you are using a loop (While, For), then using shift registers are appropriate means for routing values so that they are used by other sections of the code, later. One thing you must respect with LabVIEW is the dataflow. That's where Locals often fail.
I am not copying the Local Variable from one VI to another.
I am not copying the Local Variable from one VI to another.
The Data Communication panel is one of the panels that shows up in the Functions pop up list when editing the Block Diagram. It is the panel that includes the Local Variable function.
I don't know if the invisible item that was inserted in my block diagram was hidden or not. All I know is that the Errors List said that it was a Local Variable and that it was not connected to anything. I couldn't select it to get more information. All I could do was delete it.
You did not address my questions about why the Copy and Paste does not work properly for my Local Variable. Maybe it's a sign from the Software Gods not to use them LOL!..
So if I understand correctly, you are trying to copy & paste the Local Variable from within the same VI. How large is your block diagram? Did you try right-click on the variable and select "Find > Local Variables"? If it's a block diagram larger than 1 single screen (which it shouldn't), then it is possible that the Local is hiding beyond the screen. You should find it as I described earlier.
See my comments in red above.

Cannot insert field or paste in existing Local Variable (container of booleans)

Cannot insert field or paste in existing Local Variable (container of booleans)... TestStand 4.1.
This is very strange, especially since I have done it before.
The "paste" and "insert field" selections are greyed out and disabled from the right-click menu. I have tried everything I could imagine, and searched various combinations of posts. I am sure it is something redicoulously simple, bu I cannot find the redicule to solve this annoying issue.
The local variable is a container of booleans. It has 90 elements and I need to add one more. I cannot edit / rename or do anything with this Local. Must be karma (for thos who know me in the LabVIEW forum). Usually, you right click, insert field and it's there.. Not this one..
Has anyone seen this before? Closing and re-opening TestStand did not change anything. There is a matching cluster in LabVIEW which feeds the local in TestStand.
It is a container of custm data type. The Edit Flags are ok (edit is allowed). Can't think of any other valuable info..
Solved!
Go to Solution.

I should correct an erratum in my original post..
Since I am not the original author of the code, I am not sure it is a custom container. As a matter of fact, I don't think it is.
It does not appear in the custom data types. So it must be a Local.
I will attempt to clarify what I am dealing with... (TestStand 4.1)
Maybe pictures are worth thousands of words.
As with typical TestStand projects, there are various variables: Locals, Parameters, FileGlobals, etc.. Nothing odd here.
The one I am concerned about is the Options_Present which is a container of booleans.
I am sure I have edited this one before. Although I seem to recall that it was automatic after changing the cluster in LabVIEW.
Within the Locals, the 2 that are underligned in red do not allow to edit anything (change name, add, delete, paste).
Trying to Insert Field or paste are not possible.

Convert local variable to global - labView

I have a sequence with a VI that contains a local variable array. Now I need that data saved for use by a VI in a later sequence. Can locals be converted to globals or must it be re-created and all references to it changed?
Thanks,
jvh

Hi,
If you are using the SequenceContext as the reference, then your lookup string to your variable would need to change.
eg "Locals.MyArray" would become "StationGlobals.MyArray"
Does this help
