Is there a possible way to refer an object through it's name in Vb.Net?The case is, I have menu items created in my designer with names such as MenuA, MenuB and MenuC.On the database, I created a table consisting the list of all available menus in string format : MenuA, MenuB all the way to MenuZ.
Also I created a dynamic table consisting the user permission, what menu is accessible by a certain user.So when I started the app, it will get the name of menu assigned to the logged user, and start to turn the Visible property to TRUE.If it was a Control, I would just loop through it by Parent.Controls.Find(FoundMenu, True).My problem is most of it is not a control, it is an Item added to the Control, or even another SubItem added to the Item.So how can I found an object in my UI only by it's name?
SearchQuery = "SELECT menu_name FROM tbl_menulist menu, tbl_user user WHERE menu.id_menu = user.id_menu"
QueryReader = ExecuteQueryReader(SearchQuery)
QueryReader.Read()

View 11 RepliesI have a bunch of string variables, string1, string2, string3 etc.At the end of my program I want to write these strings to a file, but I don't want to have to laboriously type out string1, string2, string3 etc.
It would be much easier to use a loop to dynamically refer to (string & loopcounter), ie reference the variable by dynamically concatenating its name from a string and a number. Python can do this with eval(). How does VB do it? I can think of loads of examples where it'd be useful. Otherwise I have to type out all the different conditions and that's not efficient.

I'd like to know if it is possible to refer to section of an array. e.g.
dim a(10) as integer
foo(<reference to array a starting at item 2>) 'only use items 2 to 9 of the array
...
sub foo(byref a() as integer)
<do something with array>
end sub
Note that I don't want to copy the array to a new array or pass in indices, if I can avoid doing so. Subroutine foo should be able to process the array without knowing if it gets the whole array or just a section.

View 4 RepliesI have a bizarre vb.net problem.I'm working with a 3rd party library with a namespace called Telerik.Webcontrols. The library is in a web site project that I am in the process of converting to a web application project.
Telerik.WebControls contains a class called RadAjaxControl.In the original web site project, I have code that looks like this:
public sub page_load(...)
dim foo as Telerik.Webcontrols.RadAjaxControl
Once I convert to a web application project, it says that Telerik.Webcontrols doesn't exist.
However, the truly bizarre thing is that the following code does compile:
imports Telerik.WebControls public sub page_load(...)dim foo as RadAjaxControl
I have a label testlabel. is there some way I can refer to it as:
dim t as string = "testlabel"
(something here referring to the OBJECT with the same name as the string).text = "mytext"
? I have 50 labels with text to change and would love to be able to:
for i = 1 to 50
dim t as string = "testlabel" & i
convertsomehow(t, label).text = "mytext"
next
so that this would change testlabel1, testlabel2, testlabel3, ... , testlabel50.
I have a problem with using a script that adds a NiceEdit toolbar to a text area when that text area is within an Ajax tab.I want to know if I should refer to it in a different way than just the ID.I mean the ID of that text area, I tried to take the text area outside the Tab Container, it works, but when I return it, it simply doesn't.[code]
