VB / VS 2010, Incrementing Control Names At Runtime
Apr 25, 2012I am coding an invoicing application. The user should be able to add a new line to the billing section of the invoice by selecting a product from a ComboBox, which subsequently fills out various other fields (price, description, etc) based on the selected product.
My problem is this: When the user adds a product, I would like the program to automatically generate a new line for the next product. It seems like the only way to accomplish this would be to create a new set of controls with an incremented name, i.e. Product1, Price1, Desc1 for the first product, Product2, Price2, Desc2 for the second product, etc. Is this possible, or am I going about it all wrong?
C# - Decompiling .Net Assembly Produces Code With Invalid Member Variable Names; Names Starting With $STATIC$?
Sep 5, 2011I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?

C# - Accessing Members With Case-sensitive Names Across Languages In .NET
Apr 14, 2009I just came across an interesting scenario. I have a class in C#:
[Code]...
As C# is case sensitive, this will treat the two variables A and a as distinct. I want to inherit the above class in my VB code, which is not case sensitive. How will the VB code access the two distinct variables A and a?
Javascript - Accessing Elements Of JSON Object Without Knowing The Key Names
Feb 25, 2011Here's my json:
{"d":{"key1":"value1",
"key2":"value2"}}
Is there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?
The reason my json is structured like this is that the webmethod that I'm calling via jquery is returning a dictionary. If it's impossible to work with the above, what do I need to change about the way I'm returning the data?
Here's an outline of my webmethod:
<WebMethod()> _
Public Function Foo(ByVal Input As String) As Dictionary(Of String, String)
Dim Results As New Dictionary(Of String, String)

View 2 RepliesConstruct Object Names At Runtime?
Jul 15, 2011Is it possible to construct the name of an object (in this case, a Panel control) at runtime?
What I want to do is change the Backcolor of one Panel that is a member of about fifty panels. I can get the string of the name from the Sender in a RadioButton CheckedChanged event. So what I want to do is something like:
PanelName = sender.parent.name & ".BackColor"
PanelName = Color.Red
(I realize that the syntax above is invalid. I'm just using it to try to get the idea across.)
I can do what I need with big, fifty-element Select Case blocks, but the code is so repetitive that I was hoping there was a more elegant way.
Accessing User Inputs In Textboxes Created At Runtime?
Jul 13, 2009I have created a page that creates a number textboxes at runtime depending on the result of a database query, (ie one textbox per row in query result). My problem is that I can't for the life of me work out how on earth to access the text from the textbox that is posted back to the server by the user when they press submit.

Apr 6, 2010how to handle movement of buttons that are made in runtime. What my program does is writes the name of a button that is made in runtime, the left, and top cordinate into a textfile.

Each of the three components are loaded into an array. how can i call the buttons it i am unsure of the name. Possible answer could include using sender, addhandler.

Pointers - Accessing Variable Addresses In .NET?
Dec 23, 2009I have to upgrade a legacy VB6 app to VB.NET; this app uses a function call from a .dll that takes a memory address as one of it's parameters.

Accessing Multiple Form Controls Using A Variable For The Name?
May 23, 2012I'm trying to iterate through a group of ComboBoxes and set a property using a concatenated string & variable to represent the name of the control. However, I can't get the instance of the form to recognize the (String & Integer_Variable) as one of its controls -- and so it doesn't recognize any of the appropriate properties or subroutines as members of the System.Windows.Forms.Control.Is there a cleaner way to do this?

If tempValue < Me.("ComboBox" & myTempCount).Items.Count Then
ComboBox.SelectedIndex = tempValue 'appears to work -- how?[code].....

Asp.net - Update Linq To Sql With Variable Names?
Apr 15, 2012im pretty much a beginner to using ASP.net and linq to sql but what im trying to do is update a column of a table based on a variable. at the momment i have
Dim db As New sqldcDataContext Dim update As tableName = (From i in db.tableNames _ Select i)
i think this selects everything, how could i have two variables, one to store what table to update and the other what column. is this possible?edit: sorry for being unclear im trying to make this as dynamic as possible so i dont have to type in the exact table/col names. something like this but in the linq to sql syntax.
mysql_query("SELECT * FROM ". $table ." WHERE `" . $column . "` = "" . $data ."");

Creating Variable Names From Other Variables?
May 20, 2010how do I DIM a variable's name using previously declared string varialbes? I have been using PERL for processing data stored in text files but I now have a business need to use VB2008. I would like to do something like this:
dim name1 as string = "ABCD"
dim name2 as string = "123"
'here is the part that I don't know how to do - create a 3rd variable name concatenated from name1 and name2:
dim string.concat({name1,name2}), or maybe use a counter in a line like 'dim namex as string' with x being a counter value.
Essentially I want to dim variables using text strings extracted from a file. In PERL I have declared literals and arrays, such as 'my @$name1', which creates an array named with the contents of $name1. In VB2008 I am not sure how to make this work with the DIM statement.
Stripping Variable Names From Assemblies
Mar 29, 2010I'm trying to reduce as much as I can my VB.Net assembly side, and I just figured out that all variable names were kept unchanged in the actual assembly. Since I tend to use pretty long var names, it adds up and, by running dotfuscator on my assembly, I could shrink it by as much as 10%.

Access Private Class Variable Names?
Jan 9, 2009Trying to understand the best way to do this and I'm can't get it figured. Here's basically what I have:
Public Class CardParsingClass
Private iAcctIDStart as integer
Private iAcctIDLength as integer
[code]....
I've only included 2 of the class level fields here but there are actually 30, so that's why I was hoping to be able to send the name of the field to set and the value to set it at in the SetValue function. So in some other routine in the program I'd like to be able to issue the following call:
SetValue("iAcctIDStart", "3")
But then when I get into the SetValue routine, I'm not sure how to proceed. I thought about a case statement that would basically be this:
select Case strFieldToSet
case "iAcctIDStart"
iAcctIDStart = cint(strValue)

Parse Variable Names And Operate From String?
Jun 10, 2011I'm using a Microsoft Word form template to create objects in a form programatically, so depending on the information read by the program from the template.
So, I've got some fields where I store formula data for the form, in which I specify that the value for that field is obtained by multiplying other fields in the template. So I store in the string something like this:
"Text1.Text * Text2.Text"
So I need to convert these string values into variable calls to actually operate these values.

Repetition For List Of Settings With Unique Variable Names
Aug 12, 2011this website seems great and this is my first post. Sorry if this has already been answered but I have been searching for a long time. I have a program with a list view in details mode. I have it load column settings (visibility, display index, width, etc.) when the form is opened and save them when closed. There are many columns...about ten so far...like folder, file, size, etc. Is there a way to access variable names from the values of other variables?

.net - Populating A List Box With Variable Names From LINQ Generated Class?
Nov 17, 2009I'm quite new to Visual Basic - using Visual Studio 2008 and can't seem to find a way to do the following:
I have a few tables in a SQL Server database and have used LINQ to SQL to create classes of those tables.
Here's a cut down example of what I'd like:listbox1 filled with table names - APS, SMPS, WCPC, CFLAPS
Then from the SelectedIndexChanged event, listbox2 should populate column headers of the selected table.
I have no issues getting data from the database, and can access all of these headers through the anonymous type objects created from a LINQ query (eg APS.ID, APS.count etc), but populating a listbox with these variable names rather than the data inside them seems rather elusive.
This is probably a cross platform coding question rather than VB specific, so if you have a solution in C# or whatever I'd be happy if you could let me know.
Reflection - How To Get Variable Names Types / Values In Current Class
Feb 1, 2011I am working on a project where my class has to execute VB code provided by the user, to make it simple I am trying to recreate my own eval function, I am using the following code I found on the web to do this task.
Imports Microsoft.VisualBasic
Imports System
Imports System.Text
Imports System.CodeDom.Compiler
Imports System.Reflection
[Code] .....
The problem with code is that it can't access any variables or there values, so I have decided to get the variable names, there values types and there types dynamically and recreate them in the class that is being created dynamically. Any way to get the variable names there types and values in the current class or method, so that I can recreate them, and execute the user passed code, the user knows what variables are in the current class or method and there datatypes but he don't know there values as they may have changed, so he can't initialize them. Is there a way to do this, this code will be called in an asp.net page on page_load event, the code passed by the user is stored in the variable vbCode that is passed as a parameter.
Visual Studio Upgrade Wizard Hates Some Of Variable Names
Aug 13, 2009I am upgrading a VB6 to VB.NET project using the upgrade wizard.I know this is going to give me a lot of grief, but I am trying to make the old application useable. I'd rewrite it if I had time but am currently finishing up a summer internship and would like to get something working.One thing the wizard is doing that I can find no justification for is renaming of random variables. [code] For the life of me I don't understand why this is changing left. It isn't a reserved name as far as I can tell, there is no other variable named left that I can find in scope, and renaming it does not create a compiler error. [code] It does this to seemingly random variables throughout my project. Anyone have ideas as to why it doesn't like some of my variable names?
