VS 2008 Declare The Variable Along With All Declarations In A Module?
Feb 4, 2012
I have an issue with variables that are used to name For-Next loops. I have had this problem in a couple programs but not consistently, i.e. some variables work, some throw a warning (not an error).
The situation is this. I declare the variable along with all my declarations in a module-
Module MainModule
Public Counter1 As Integer
end Module 'MainModule
[Code]....
The type for variable 'Counter1' will not be inferred because it is bound to a field in an enclosing scope. Either change the name of 'Counter1', or use the fully qualified name (for example, 'Me.Counter1' or 'MyBase.Counter1'). In the past I've always broken down and changed the names to get rid of all those ugly warnings. Sometimes I have eliminated them from being declared in the module and declared them at call time. This is not how I program and I like to keep consistency throughout.
how I can get rid of this spotty, on-and-off nonsense? There is obviously a lot I don't understand about VS and I would have never taken it up but would have stopped 3 languages ago if I weren't forced into bulkier and bulkier languages (sorry about the rant. I feel OK now).

It is my understanding that all modules are initialized and that all their variables are set up prior to MyApplication_Startup. I have code that has worked well for quite some time (XP and Vista).The Myapplication_Startup code references variables and code located in a Module.However, with Windows 7 this does not work.Anny reference to a module (Data, SUB or FUNCTION) throws a Type Initialization error at runtime. How can I correct this behavior in Windows 7?

Although I have been programming for many years, successfully, in many different languages, translating my large Word VBA application into VB 2008 Express is driving me crazy. While I understand the theory of OOP and have even been on object-oriented courses, it seems I can't declare my objects correctly and use them in my code. As far as I know, I'm not trying to do more than the "language" is capable of doing, but here goes.
I want to start with "aList" which would be a Collections.Generic.Dictionary(Of String, String) object. Then I want a "bList" which is also a a Collections.Generic.Dictionary object. I would like each bList item to have a few individual simple properties (like a Byte and a String) then an aList instance as well. The application then gets a bList key value from the user, "copies" the corresponding bList item values into a work area, and does the necessary processing using the various bList(aList) / aList(bList) item values from the work area. I say "copies" because I assume that part is simply going to be a pointer copy rather than a long copy of lots of strings. Note that I really don't want to start using arrays here, as the application makes alot of use of Word VBA Dictionaries and I'd like to keep it that way if I can. Incidentally, so far, I have all my global data declarations in a separate Class, not on any of the application's forms.

I've read several articles and questions/answers that conclude the best practice is to let the JIT compiler do all the optimization for inline function calls. Makes sense. What about inline variable declarations? Does the compiler optimize these as well?
[Code]...
Of course I prefer the latter because it's easier to read and debug, but I can't afford the performance degradation if it exists. I have already identified this code as a bottleneck -- No need for retorts about premature optimization.

Is it possible to declare a variable using the text of, lets say a string, as the name?If u dont get it im looking for something like;Dim Var + string1 As PictureBox..In the code "Var" is the start of the name and "string1" is the end of it so if string1 was "Hello", the picturebox would have been named VarHello.

I have a public readonly variable in a module, but when I try to set it in my form load event for the first time I get 'ReadOnly' variable cannot be the target of an assignment. It is my understanding that a ReadOnly variable can only be set once and after that you would get an error when setting it.

What I am used to declaring database connection is that in every form I type the codes for it which is a tiring way. Now, I want to use module instead but I really don't know how. And also, how will I call the connection to every forms I created?

What I'm supposed to do is declare two module level String variables name strCaptital and strChoice and I did that. At least I think I put them in the right place, however what I'm not sure what to do is and I started is that I'm supposed to code each state radio button's click event procedures so that each assigns the appropriate capital to the strCapital variable and then each removes the contents of the lblMsg control.url...

I have a form with 2 controls, a textbox and a button. The user will type text into the textbox and then when they click the button the text that they entered will be added to a List Collection. You can see the code below. There is just 1 problem. Where would I put my declaration of my List Collection so that it holds the values and does not start at the first element everytime the button is clicked?[code]

I'm trying to learn more about assembly security (something I have basically neglected until recently because security in general is such a huge topic), and I have a question about CAS assembly level declarations.I get how to use them (basically) and the more blunt points of the subect, but I'm still not clear on where assembly level declarations should be made. Basically, where in the solution do you put:

I have been debugging my code for a while and looking at posts in other forums, but it seems to be that everyone has a different problem than mine and what works for them will not work for me.My dropdown list is supposed to filter a gridview by choosing all the Companies that are associated to a certain product. The solution I have found online is that most people did not have DataKeyNames set in their gridview. I do have this set, but not to CompanyID. It wouldn't make any sense. So I have no idea what I am supposed to do since this is the only answer I have found.
<asp:DropDownList ID="ddlCompany" runat="server" DataSourceID="dsCompanyFilter"
DataTextField="CompanyName" DataValueField="CompanyID" AppendDataBoundItems="true"
AutoPostBack="true">

I have searched online for a few hours to try to figure out how to do this, but nothing I found really makes sense, so could someone please tell me, in a simple way, how to do this?
Let's say I have a text box that the user fills out, named textbox1. And I have a combo box, named combobox1, which contains the choices A, B, C. And then I have a button named submit_button.
Each time that the user clicks submit_button, I would like to dynamically create a new variable. This variable should be named the same as textbox1.text, and should contain the value of combobox1.
For example, if the user types "blue" into textbox1, and chooses value "C" from combobox1, and then clicks submit_button... then the following variable should be dynamically created, like..Dim blue as String = "C"
And then, after that, if the user types "red" into textbox1, and chooses value "B" from combobox1, and then clicks submit_button... then another variable should be dynamically created, like...
Dim red as String = "B"
And each time the user submits new information into the textbox and combobox, a new variable should be created.Is it possible to have the program automatically create variables like this? If so, how?
My actual project is much more complicated than this, of course, so the above is just an example. But if I could figure out how to solve the problem in this example, I could figure out how to solve the entire project.

I am working on an alarm system software, which is SMS-based. I am using a GSM modem to receive the SMS when a client's premise security devices are triggered. The types of SMS text received will be like for e.g. "fire alert"(when devices triggers), "fire clear"(when devices are 'reset').
My program can detect real and false alarm, it works this way, i will input a premise site-map on a picture box at the main GUI, i can then create buttons at run-time and drag them to the respective position on the map. The buttons created have their text set as the client's block number referred to the database. So basically, a button represent a client. When a device in the client's premise is triggered, a SMS will be sent and my GSM modem will receive it, process the SMS and the button representing the client will start 'flashing' showing that the client's premise is under danger. Then when the button is clicked, which acts as an acknowledgement, will display the client's information on labels and turning that specific button to red color. Finally, when the device is 'resetted' in the client's premise, it will send another SMS to my GSM modem, after processing, the button will be back to normal.
But my program has detect false alarms also, the first part is similar to mentioned above, client's premise security device triggers, SMS sent, SMS received by GSM modem, process SMS, button 'flashing'. Secondly, if the alarm is false, it will be automatically 'resetted' or the client may 'reset' it, then a SMS will be sent to my modem, turning the button to 'flashing' green in color. when 'acknowledged' will display the client's info and the button will become normal.
The problem here i am facing is during the processing of the SMS, because the real and false alarms both will receive the 'clear' SMS when during some stages, but the functions are different and of course the 'checking' for both functions will be different too. The problem occurs at the checking process whereby the 'btn' variable is not detected.
'Try
'AT commands to receive SMS
serialPort.Write("AT+CMGL=""REC UNREAD""" & vbCrLf) 'set command message format to text mode(1)
