I am trying to make it so when I use Me.Controls("Timer1") for example I can access specific commands for a timer such as Stop() Start(), I tried CType() and typed in "Timer" as the type but it says the control type can't be converted to the "Timer" type.
View 11 RepliesI have a small piece of code that iterates through the controls collection on a panel (below) Everything works fine until I want to focus on a control that doesn't support the selectall method i.e. a datetimepicker. Is there any way of determining the type of control and not call the selectall method when the type is datetimepicker. All my other controls support it so that's the only one I need to exclude.

I seemed to have have ruined my settings on VS 2010... I can't get the Shapes to work just after I had fixed the problem with the PowerPacks, and then it deleted all of my shapes I had on my form after I was tweaking the code and added another shape. And ever since, the shapes make errors and I can't change there colors. I've tried reinstalling VS 2010, and changing refferences doesn't work anymore. The title is the problem I have with trying to add a shape through the code in my project, here is the code for that:
Public Class Form1
Public Circle As New Microsoft.VisualBasic.PowerPacks.OvalShape()
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I am creating a User Control where I have a property called Items. Items is of type LibraryPanelBarItem Collection (custom class) which contains a collection of LibraryPanelBarItem objects. I would like to be able to add these at design time by using the Collection editor that VS uses for adding things such as treenodes/listviewitems. Ideally I would also be able to declaratively add them to the html syntax. I can get the Items property to show up but I get no intellisense to add the items between the opening and closing tags.

If I remove the datagridview code the 1st part of the program runs fine and works well, it is when I add in the datagridview that the error occers.
I am trying to learn to create an array of objects, but I keep running into errors and am hoping someone can explain what I am doing wrong in my code.
To start, I have the following class:
Public Class CD
Private _name As String
Private _price As Double
[Code]....
Which produced the error: Value of type '1-dimensional array of CD' cannot be converted to 'CD'
I need to take 6 user entered dates and compare them to a date pulled from a database & stored in a variable. If greater than 6 weeks, then some action needs to take place.When writing the code, I get the following message (before compilation). Value of type 'Date' cannot be converted to 'System.TimeSpan'. [code] Within my code the 'dt' in the line above is underlined with the error message appearing on mouseover. I have tried using CType, as in dt = CType(Session("dt_occurence"), DateTime) in the hopes that might work, but it doesn't do it.
View 11 RepliesI think I am missing something really simple. I want the user to be able to select a particular interest rate and term from radio buttons (in separate groups), the values for the buttons are to be stored in an array. Then they click the calculate button and it does it's magic and pops the result in to another field. I think I have things set up roughly the way it needs to. What I'm running in to right now is the term variable in the calculation formula is coming up with a blue underline stating that "value of type -1 dimensional array of double cannot be converted to a double". So as a result nothing is working right. I don't know where exactly I've gone wrong. If I change the data types nothing seems to change.

I have a project that you enter someone's name, home town and initials saves it to an array which later is produce into a pie chart.
The question is: The class has one method called addCompetitor that takes String parameters to indicate a name, home town and initials, and an Integer to indicate the position in the tournament. The method creates a Competitor object and stores it in the corresponding element of the position array.

[Code] As you can see, the code in the client side calls a function in the Server that generates an array as output. And this output SHOULD be loaded into the new array that was created in the client side. The case is that it is not allowing me to do that. The blue underlined row gives me the following error: Value of type 'ClientTest.TestService.ArrayOfString' cannot be converted to '1-dimensional array of String'.
I cannot see what is wrong, the function generates the same output type as the new var that is expecting to load it. Why data cannot be 'converted'? And what would be the solution to turnaround this problem? PS: Actually my function is a bit more complex than that and evolves a DB query, etc, but I reduced its code to simplify as the problem is occurring just in the array transfer.
