Create A Button Or Label That Is On A Form That Has Also Been Created Programmatically
Sep 11, 2009I have code that refers to controls like buttons and labels and textboxes (obviously), but i want to create them programatically, how can i create a button or label that is on a form that has also been created programatically. Here is what i have:
Dim frmIndashone As Windows.Forms.Form
Dim vscPage As Windows.Forms.ScrollBar
Dim lblPageNum As Windows.Forms.Label
Dim txtVector As Windows.Forms.TextBox
Dim txtPageCode As Windows.Forms.TextBox
I am asking because i have a With statement that assigns different values to the different things that looks like this below:
RaiseEvent Load(frmIndashone)
With frmIndashone
.vscPage.min = 1
[code]....
But i am told on everyline of the second snippet that vdcPage, lblPageNum, txtVector and txtPageCode are not members of windows.Forms.Form, How can i make them members?

View 3 RepliesDeclaring A Object - Instance Of An Object To Be Created When A Form Loads Or Another Class Is Created
Oct 5, 2009If you want a instance of an object to be created when a form loads or another class is created, you have two options:
Public class example
private IAmAObject As IAmAObject
public sub new()
[CODE]...
Or like this:
public class example
private IAmAObject as new IAmAObject
public sub new()
[CODE]...
I always use the first one. It's more type work but I think it's neater. How about you people and is there any real difference between the two?
VS 2010 : Event Handler For Dynamically Created Controls?
Sep 14, 2011I have to create controls for inputting info to create people objects in the program, because I don't know how many people they are going to input, I have a button that they can press to add more fields.
I need to add a doubleclick event for these dynamic controls (text boxes), how can I create an event for them if they haven't been created yet. Also, as far as I know you cant make a variable part of an object name while declaring it. I need to do something like
Dim dynamicText & (Append variable counter each time a box is made)As New TextBox
dynamicText &variable counter. Name = "TimeTextBox"
dynamicText.Text = "SdgsdG"
dynamicText.Location = New System.Drawing.Point(100, 100)
[code].....
Also is there a way to like copy and paste a group of controls via code instead of having to code each individual one like if I had to do a text box along with a combo box and a lable all at once, can I throw it into something so I only have to recreate the container?
How To Perform Onkey Event In An Excel Add-In Created With Visual Studio 2010
Apr 17, 2012I am creating an Excel Add-In using Visual Studio 2010. I would like to run some code when users clicks a combination of keys.Here is the code I have got

ASP.NET Add Indent To Programmatically Created File?
Apr 4, 2011After searching Google, and finding only answers to XML indent, "just use Visual Studio's auto indent" and "that would be crazy to write your own auto-indenter" I've decided to come to the good place: StackOverflow.Question:
1. How do I add an 'indent' to a programmatically created file?I would be generating the files via the System.IO class / streamwriter, unless someone can tell me of a better way, I just want to generate a file from my asp.net page, a windows app or possible a batch file (well, maybe not this last one)... to generate a class file, such as Employee.vb OR EmployeeDAL.vb

Close Forms Created Programmatically?
Feb 21, 2009In my program it detects if there is more than one monitor connected. It then creates a form on each monitor screen and you just click on the screen that you want the program to run on.
Here's where I'm having a problem. Everything works great, but when I load my MAIN form how would I call those programmatically created forms? I can't just do frmYou.close.
Here's the code I use to create the forms.
Public myScreen As New Point
Public ScreenReady As Boolean = False
Public sX As Integer'holds screen x width
Public sY As Integer'holds screen y height

.Net: Connect SQL Table To Programmatically Created DataGridView?
Dec 17, 2009how to connect a SQL Table to a DataGridView that was previously created programmatically. Basically, at run-time the user names and creates several empty SQL Tables and DataGridViews. After that the user selects from a combobox the name of the SQL Table and DataGridView that they want to import data into, then clicks a button named "Import"...after clicking "Import" the user navigates to an Excel file, chooses a worksheet, clicks a "Continue" button and then the code successfully connects to the Excel import file and SQLBulkCopies the data to the SQL Table...next I need the imported data in the SQL Table update to the DataGridView...this is the part I can't figure out.
The challenge is the datagridview isn't hard coded it was created and named programmatically at runtime. So now the user selects the name of the SQL Table the data resides in and the name of the DataGridView from the combobox "moduletableCB" and I need the code to update the datagridview.

Programmatically Created Controls Show Up Intermittently?
Feb 22, 2009Now everybody knows that creating GUIs that have lots of repeated elements that are evenly spaced by hand is for chumps; all the cool kids use loops and add them at runtime. Given that being one of the cool kids is one of my top priorities I decided to give this a go - as my current project involves creating a grid of check boxes and then chunking them together under one event handler. In my experience - an nice effective way of dealing with grid like structures (2D arrays if you will) is to use nested loops such as:
For intY = 0 To 9
For intX = 0 To 9
Dim chk As New CheckBox

When Calling New On An Object - Can The Object Being Created Refer Back To Its Caller
Nov 11, 2010I hope the question makes sense, anyways. I'm looking to know if in VB.NET, when we call an object's constructor, is there some kind of a reference that points back to the caller? I'm interested because of a corner case where I want the object being created to first be able to validate the existence of some data in the caller before it allows itself to be created. If this validation fails, I plan on throwing an exception. This corner case will never happen at runtime unless the object being created is used improperly by a programmer. The object being created is not inheriting the object I want it to validate, so I can't do anything with the MyBase qualifier.
It's bit of a "future-proofing" issue that I have a (bad) habit of doing. Not critical -- I can always leave stern comments behind as a last resort. Wanted to know if this was possible.
