I need to programmaticlly check one RadioButton1 in GroupBox1 in my Form.The name of RadioButton and his parent GroupBox is received from global variable 'names'.How to change GrpBx1 to names(0)?
VB.Net
Dim names as String() 'GrpBx1,RadioButton1
'WORKING but not exactly what I wanna while it's fixed to only one GroupBox:
CType(Me.GrpBx1.Controls(names(1)), RadioButton).Checked = True

The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"

So I do not know at design time if the var ms is going to be a stringreader or a memorystream. So I am trying to do basically this:
Dim ms as object = myfunction...
Dim mytype As Type = ms.GetType
Dim returnedobject = ser.Deserialize(CType(ms, mytype))
But I get an error saying "type mytype is not defined". How can I do this?
I am having an issue using a datagrid. I can use it fine on my development machine in VB 2005. But, when I deploy it to a client and they try to access the datagrid this message comes up:To run this example, replace the value of the connectionString variable with a connection string that is valid for your system.
Both machines are running Windows XP Pro (SP3). Is there some type of assembly for datagrids that I am missing in my application or some prerequisite that I need to install as part of the solution.
Okay this one might be a little tougher. I'm using VB that looks like this:
string = Replace(string.ToLower, chr(63), "A")
But I also want chr(63) = "B" as well, like this:
string = Replace(string.ToLower, chr(63), "B")
My problem is that when chr(63) is at the end of a string I need it to be B, and when it's not the end I need it to be A. I suppose that I can use an if/then/else statement. Is there a way to do this?
I'm creating a method to replace variables in strings, I'm going to share an example of how I'm replacing values and can see short falls in how what I'm doing. Here's a stripped down example of what I'm doing. It replaces a variable with the date specified, so %today(-1) would give me yesterday, %today(2) would give me two days from now.

I am developing a new class which is a control that inherits from the "Panel" class. In this new class, I have three objects that are generated every time I create a new instance of the class. For simplicity, I will call this class "garage" and the three objects "BMW," "Lexus," and "Acura." So each new garage has three types of cars.
how can I share a variable from the Parent class with all of it's child objects? i.e. The garage has an array variable called "tires" which all three cars use. Rather than create each car object with the tires parameter, I would just like to keep the tires parameter in the parent class so that all my child objects can use it. I know that normally the parent class should provide the child class with all information when creating the child but it would seem redundant to pass the entire tires array each time since all three cars use the same tires and the tires object never change.
I have created 2 forms (Parent & Child), i want to store the unique textbox value to a variable into the parent form.

Using VB or C#, I am getting a string of variable length from the database. This information is sensitive information that only certain users will be able to see.I have two cases that will use the same logic (I think).scenario 1: replace all characters with xscenario 2: replace all characters with x except the last 4 characters (assume length > 4 - this check is being done).I thought that this would be easiest using Regex.Replace(input, pattern, replacestring). As opposed to a lot of string handling with substrings and forcing a length of 'x's.

I am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?
I have a Type manager witch creates a ORM type for each model.Inside this type all the properties are overwritten to detect inside the parent class witch properties are requested (for lazy loading) and witch properties are changed (for saving).
This already works when loading objects from the database, but i would like to be able to detect this also when i create a new instanse of a model.Is there a way to replace the reference of the object by a child object?So when i create "New User()" the actualy object created on the pointer is "New User_ORM()"..
This is a challenging one that got me stumped while I was coding today. Suppose I am running the Sub Test1() and Test2() and would like to print out the value of the Shadows method of the instance of the object I am passing in to TestCall() (see below - it is clearer) using the following restrictions:
Can't change the contents of Class A, B, and C
Can't change Sub Test1() and Sub Test2()
TestCall() can't have an if, select case etc. statement that tries to figure out the type

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.
dim l = Mainform.subform.listofdata
Edit:I am using visual Studio 2008. Winforms, form designed using designer. In my mainform I am doing this
Protected Friend frmMain as Mainform
frmmain = new mainform
In frmMain I am doing this

have a look at this code Dim colors() As KnownColor = CType(System.Enum.GetValues(GetType(KnownColor)), KnownColor()) Since CType is a function that returns DataType ,But here as in the code it seems that CType() is returning array having values that is assigned to color() array. How this is happening?
View 3 RepliesI have a number of different object types that I would like to pass into a function. All my objects are created from classes with a .Description property. Is it possible to determine the type of object for use as the 2nd parameter in a CType call at runtime? e.g. Debug.Print CType(MyObject, TypeOf(MyObject)).Description (I have Option Strict On) I get errors when I do this.

I am an experienced C/C++/C# programmer who has just gotten into VB.NET. I generally use CType (and CInt, CBool, CStr) for casts because it is less characters and was the first way of casting which I was exposed to, but I am aware of DirectCast and TryCast as well. Simply, are there any differences (effect of cast, performance, etc.) between DirectCast and CType? I understand the idea of TryCast.
View 2 RepliesI turned option strict on, wich gave me some errors. The errors are quite easy to fix, but it seems like there are several ways of doing things. [code] 'previoustime' is declared as a TimeSpan, and the column "sluttid" is defined as a TimeSpan-column.Now, as far as I know, there are two ways of solving this; using CType and using DirectCast, like this: [code]
View 4 RepliesAssume that I have this declaration (according to MSDN):
Private Declare Function PostMessage Lib "user32" ( _

ByVal wMsg As UInteger, _

And this is how I use it:
PostMessage(hWnd, 516, CType(2, UIntPtr), CType(0, UIntPtr))
Option Strict is turned On. So the questions are:
1. Do I need to use UIntPtr in declaration or it will be better to use UInteger?
2. Do I need to use CType function in these cases or there is a better way for this or I need to avoid declaring pointers?
does your IDE ever get amnesia?in the line before it is clearly defined.in the following line it is not.Maybe it's a faulty translation from Tangible Software.the C example i'm looking at:
IAnimatedMeshSceneNode* newNode = (IAnimatedMeshSceneNode*) oldNode->clone();
translated as:
Dim newNode As IAnimatedMeshSceneNode = CType(oldNode.clone(), IAnimatedMeshSceneNode)
had to make a dummy for it because i can't use arrays with CType.
The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below.

The below is a snippet from VB that I am porting to a C# rewrite. My question is what is receipt_date after the assignment? Is it still an object or is it a string?
Dim receipt_date As Object
receipt_date = CType(dr.Item("RECTDT"), String)
Would this be the correct C# counterpart?
object receipt_date;
receipt_date = dr["RECTDT"].ToString();
After both of these execute would the VB version, receipt_date be equal to the C# version?
