View 3 RepliesWhat I am trying to do is scan through the arraylist that has the number of the label control and concatenate this to the word "label" to end up with "label1", "label2", etc. Then I can then set it's visible property. The values in the array are based on tests in the code.
I haven't hit upon the right way to convert the string "label1" to the name of an object.

I am looking for a way to convert my List(Of string) into an Object in vb. So in the end it would be the same as declaring Dim cArray() As Object = new Object. Can anyone point me to how i can achieve this? I cannot use the LINQ .ToArray as that creates a string array and this is not acceptable for my work. I need to pass this object into another one that has the parameter (aArray as Object).

I have a problem here for converting object of array to string of array in my VB.Net code. The object of array is quite long and contains 6 sets of data here.
Dim varReturnResult As Object
Dim varMapData As Object
Dim StrMap() As String
varMapData = varReturnResult(2)
StrMap = Split(varMapData, vbLf)
I encountered this error "Conversion from type 'Object()' to type 'String' is not valid." when trying to retrieve the StrMap value.

View 4 RepliesHere's my problem :
Let say I have a variable called A
Which value is 100 ( A = 100)
In a form, I have a textbox, where I want to enter a variable name
textbox1.text="A" for example
Then I want to display the value of that variable
msgbox (somefunction(textbox1.text)), which will popup 100
I read some info about Reflection, but they all seems to refer to controls and not simple variable
I have a string value of form names in my DB so when my condition passes, the variable string will take over the value , then that value will call the form(variable) as string.

I have a string variable that contains "19:39:43", I would like to convert that to a date object. When I try I get a formatexception was unhandled error during debugging. I want to convert it to format of hours:minutes:seconds but cannot see how this can be done..
Code snippet:
Dim strtxt As String = "19:39:43"
Dim Datevar As Date = Date.ParseExact(strtxt, "HH:mm:ss tt", Globalization.CultureInfo.CurrentCulture)
I tried just "HH:mm:ss" but not sure if that worked...
I have an object with a number of properties (let's say object.one, object.two, object.three). There are about 30 of these properties and they all hold a string ("Pass" or "Fail"). Right now the existing code checks whether the property has value "Pass" or "Fail" and then runs some code that prints stuff out. That is, the same snippet of code is duplicated 30 times, one for each of these properties.
The code looks something like this
If (object.one = ... )
...
End if
If (object.two = ... )
...
End if
If (object.three = ... )
...
End if
I want to use a loop to clean this mess up (each block is huge), but am not sure how to do it. I was thinking perhaps there was a way such that I might be able to construct a string like "object.one" and run some function that will tell the compiler that this is actually an object's property? That way I could create an array containing the object's name like my array = {"object.one", "object.two", "object.three"} and then do something like, in pseudocode
For each string in my array
If (some_function(string) = ...)
...
End If
Essentially, it would take those massive blocks of duplicated code and reduce it to just one block. Is there such a some_function that I am looking for? This is in VB.net.

In Visual Studio 2008 vb.net i have created a windows forms application containing 2 web references: wr1 and wr2.
wr1 contains a public class "Person" and wr2 also contains a public class "Person". They both have exactly the same properties.
What i would like to achieve is to convert an object of type wr1.person to wr2.person. Something like this:
dim p1 as wr1.person
p1 = wr1.GetPerson(123)
dim p2 as wr2.person
p2 = p1

I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

View 2 RepliesI have a program which opens up a webpage through a WebBrowser object in c#, and does a bunch of operations with it. Now I need to integrate this functionality into my own webpage.
That means that either I need to take the c# code, and somehow make it work in my webpage itself (put in a WebBrowser object, set up event handlers, etc), or I need to somehow have my webpage open this program on my server, fire an event to start, and receive input from it. It is very important for me to use a WebBrowser object (or even WebKit.Net) because there is a lot of javascript, etc on the page that needs to be processed.
