Use CType To Change An Object Variable "obj" To Custom Class That Reference Using A String Variable Like Obj.GetType.Name?
Feb 9, 2011The 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"

Reference A Text Control Using A Variable?
May 7, 2012I have many textboxes that I need to reference dymanically. The controls themselves aren't dynamic, just the way I need to reference them.I've got several text boxes say:
txtMe1
txtMe2
txtMe3
...
txtMe100
I will need to randomly change one of the properties of the edit boxes. So lets say it picks a random number between 1-100 which is 56. So, I would want to change the background of my 56th edit box to:
txtMe56.Backcolour = Color.Gray
The only way I could think of doing this would be to have one giant select case statement to evaluate the random number. But, that is really dirty and not the best peformance wise (this could potentially get called hundreds of times) so was wondering what my options are?I tried to concatenate the random number to my generic control name 'txtMe' but it throws a wobbler. I essentially would want the following to worK:
dim iNum as integer = 56
txtMe & iNum & .Backcolour = Color.Gray

Format A String Of Text From A Variable?
Jun 29, 2010I seem to be having a problem with the Format() Function. I am trying to format a string of text from a variable so that it uses commas as thousand separators, but I can't seem to get it working properly. Here's what I'm using:
Dim testVar As String
testVar = "10000"
testVar = Format$(testVar,
When I use this code, it changes the variable's value to The strange thing is, it works fine if I use a number instead of the Variable. It also works fine if I use a "predefined numeric format" instead of my custom one. For example, if I use:
testVar = Format$(testVar, "Standard")it works just fine, but that's not what I want (otherwise I'd just do it this way.) It also works fine when I do this:
testVar = Format$(10000, And, although in the example code I've written here, it seems like I could just do it this way, in my actual program, I can't. I have to set it dynamically with the variable.
So it seems like both portions of my Format() Function are working, but just not together, and I can't seem to figure out why. anyone shed some light on this for me and tell me what I'm doing wrong? From every example I can find on the internet about using this function with a variable, I'm doing it correctly, but mine isn't working.

View 2 RepliesReference A Form From A Variable?
Nov 24, 2009I am upgrading a very large project from VB6 to VS2008. I have several forms with dozens of combo boxes on each form. I use the same combo box names for each form and want to fill them from a module with different items depending upon the calling form. In VB6, I dimensioned a public variable - FormName as object and called Set FormName = frmMyForm1 on Form Load. In a module, I was able to write the following code:
With FormName
.combobox1.additem("item")
.combobox2.additem("item"
End With
I cannot make this work in VB.Net. When the form loads I call FormName = Me. If I dimension Friend FormName as Object, I get the error message that Public member combobox1 on type MyForm1 not found. If you are attempting to access members on a late-bound object make sure it is declared public". If I dimension Friend FormName as Form, I get an error that says "combobox1 is not a member of System.Windows.Forms.Form".
I have tried both CType and DirectCast to convert the form variable from Object to Form with no success. I also tried creating a public array and storing each form name in it.
