I have code that draws a Oval onto my form.Can I create code to allow me to right click and Delete? Even better a custom menu so I can change its properties.
View 2 RepliesI had created another thread asking how to create OvalShapes during runtime... Ok, so I have that covered, but what I need to know how to add properties to these OvalShapes individually. The OvalShapes are stored in the List(Of OvalShapes) if I create a loop from 0 to the length of the list it modifies all the OvalShapes with the same propertiesWhat I�m trying to do is make like 5-10 balls collide, this is why I need these properties to be individual to each OvalShape.
View 2 Repliesive got code like the code below that creates textboxes dynamically. I want to be able to click a button and delete all of these textboxes i make, however im not sure how to do this. When i tell the program to remove the TBIndex control it does not do anything. The only way i get it to work is if i put the command in the same sub as this code. This code runs in a loop by the way.
So if the loop runs one time and creates the TBIndex control and i have a line of code right after to remove the textbox, then it does not show up on my form. But if i put the command in to remove the textboxes somewhere else and run the code the loop runs abunch of times and creates all teh textboxes and the loop is complete, then the remove control part is called and nothing happens. I just need a way to clear all the textboxes off my form with like a button. I also tried painting over the textboxes with a big grey rectangle but that dindt work.
TBIndex.Width = 54
TBIndex.Height = 20
TBIndex.Visible = True

I have created a picBox inside a function, this function then adds some properties to it and then adds to: Me.Controls.Add(thisarray(count))
View 1 RepliesI have a form with around 20 ovalshapes (the one that comes with Power Packs 3.0). I have named them p1, p2, p3, p4 and all the way up to p20. Is it possible to loop trough each shape in the form and check if the name contains a specified number? I'm thinking of something like this:
For Each ovalshape In Me
If ovalshape.name.contains("13") Then
ovalshape.backcolor = Color.Black
End If
Next

I have a BindingNavigator and combobox tied to the same BindingSource. I want to allow the user to confirm a delete after hitting the delete button of the navigator. It appears that the row gets marked for deletion after my BindingNavigatorDeleteItem_Click event handler is processed. Is there no way to cancel the delete activity from within the delete click event? If not, then it becomes necessary to store a delete flag and catch another event to RejectChanges.
I have software which is loading texts from files in folder, also if user wants to click on link he just using "click" button and it will search it for him and will open in built in browser. Thing is that some of those texts has just [URL] instead <a href.... a>
At this moment I'm using this:
For Each link As HtmlElement In webMail.Document.Links
WebBrowser1.Navigate(link.GetAttribute("href"))
Next
But I'd like to to be able to click every link with just http in text, no matter if <a href is in use. I guess I can just add <a href to any http string but I guess there must be other way to do that. Should I some how look for any string with http and then just set it as variable and then navigate or can I use other way? So for now I have 2 ideas, one replace http://... with <a href... a>, or to find any string with http and set it as variable and then navigate to that web browser...

I have an application that saves details to then be viewed in a datagridview on another form. Clicking on an entry in the datagrid (I want to make this double-click, but haven't bothered to try yet) highlights the row, and loads the values to a new form, in read-only text boxes. Clicking Edit changes the read-only value of these text boxes and allows you to edit (obviously) the contents. I have another button, Save which I want to click to commit the changes to the loaded items in the datagrid.

I have created a custom installer in VB.Net to create directories during installation. Now I want to delete those directories and sub directories during un-installtion.

I have a form that has an array of dynamically created labels of varying size based on a search from a database. The problem I'm having is that when the user searches for a different term, it looks like some of the labels don't get new values. Here's my code for adding the labels:

I've tried for loop over the controls in panel1 to dispose of any still on there in both the page_load and page_init subs, but neither had an effect. I don't know if it might have something to do with controls having the same IDs after the postback.
I have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.
I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

Say I have 3 Buttons, labelled: Unit 1, Unit 2 and Unit 3. When I click on any button I want a drawing of that unit to appear on screen at a pre-specified starting point.

If 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?
I have a series of ovals named "lamp1" through to "lamp26" and wish to change a particular lamp's backcolor.I have done this for labels (Controls("Label" & intButton).BackColor = Color.Black) but Controls does not work for Ovals. I assumed this was because Ovals are part of the PowerPack set but I cannot get any further.

In my application, I want to have 10 webbrowsers, which go to google like this.
For i = 0 To 9
Dim Browser As New WebBrowser
Browser.Name = "Browser" & [i]
Browser.Navigate("[URL]")
Browser.Visible = True
Next
So now I will have 10 webbrowsers aimed for google, right? So how do I make a loop that clicks the search button 10 times? I know I need to use member_invoke like this
Browser.Document.GetElementById("search").InvokeMember("click")
But I have no clue how to code the loop.
I have created a program that allows the user to click on screen and add many ovalshape objects. But I have got stuck as now I need to create a rightclick event for any of the runtime generated ovalshapes on screen and dont know how to refer the right click event to all the many objects?
My code for creating the oval's are as follows:-
Dim
Drg As New ShapeContainer
Dim Shape As New OvalShape
Drg.Parent =
Me
Shape.Parent = Drg
Shape.Size =
New System.Drawing.Size(10, 10)
Shape.FillColor = StampColor
Shape.FillStyle = FillStyle.Solid
But how do I write a click event now for any of these runtime created objects???

View 12 RepliesIn ASP.NET using VB.NET, you can define the wired up button click event (to an ASP.NET server control) in 2 different ways (for the purpose of this conversation - manually wiring up via button property not in question here):
Double click on the button in the designer which produces an event in the code behind with a Protected method.In the code behind, select the button from the list of controls, and then select it's 'Click' event. This produces a Private method.I understand the difference between Private and Protected; why based on how the wired up event is autocreated it generates a different Access Level on the method?
