i have this code which draws a continuous circle using a timer. Now I have to display it in the form which has a group box with loads of other fields and information. Now can anyone please tell me how can i add the circle into the group box as it can be displayed.Currently the circle is being displayed behind the group box which is not visible.
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles Timer1.Tick
Me.sweepAngle += 1
If Me.sweepAngle = 360 Then
I am currently creating a program for my own use but I need some information about groupboxes. I have 3 groupboxes with each some checkboxes in them. My question is: How do i get the number of objects (checkboxes) in a groupbox. I tried looking for the index like in a listbox but it isn't part of the controls.
I'm migrating VB6 application to VB.NET 2008In the old app I have a toolbar with icons which are stored in an imageList.Now I can't find how to link the imageList to toolbar (which is now called "ToolStrip"). It's so confusing.
I am adding a several controls to a groupbox dynamically, but I can only see one of them. I am changing the location for each one just a little so so they should all be visible. When I count the rows in "dtOptionGroupOption it returns the correct #.
'Starting location for Options. Dim intOptionLocationX As Integer = 0 Dim intOptionLocationY As Integer = 10
So I'm making a program that has a few selections from a ListBox, and when one is selected, it will clear/load items on a groupbox. However, when I add a label, it will only display the first 2 or 3 words.Here is the code I use to add a simple lable, that doesn't work:
If (ListBox1.Text.Equals("Mode")) Then RichTextBox1.Text = notes GroupBox1.Controls.Clear()
I'm trying to make a mini map for a 2d space shooter of mine; I've for the math down (I think) for when an item should appear on the mini map, but the problem is the graphic. As it stands, the graphic spills over the edge of the mini map graphic and disappears only when it's fully outside. I need it to crop the image, or at least not show it off the mini map graphic.I thought of using the sourcerect rectangle of the spritebatch.draw, but it seems to me that would only work for the right and bottom section, as I can adjust the size of the rectangle. I haven't tried this yet, but I will soon. Can the location of the source rectangle be changed in relation to the graphic that it is a part of being drawn so that I can use that to crop the left and top sides?
I can only add 4 linklabels no matter how big is the groupbox, i tried autoscroll but nothing. How can i do to store minimum 20 linklabels in a groupbox? Here is the whole code i used:
I know that there is a method for doing this but I can't find what that would be. In my program I am looking to allow the user to create new elements(with code behind them) by entering a certain keystroke say ctrl+v(doesn't matter) and adds a textbox
I have an Object structured as follows:[code]I thought this would work but I keep getting the following error: Object reference not set to an instance of an object.
I get the following error when trying to use this code.If you see that something is wrong with my design then tell me. I want to do this the best I can.Also, I am trying to figure out how to add specific players and coaches to a school. I have coaches and players in separate lists just like the school.
Private Sub populateTable() For i As Integer = 0 To SchoolList.Count - 1 DataGridView1.Rows.Add(SchoolList.Item(i)) Next
Here using VB .Net 2008. I seem to be having trouble getting group boxes to appear when I click a radio button.
For example:
CODE:
This indeed brings up the first radio button however I have other groupboxes underneath which with the same code will not appear when the radio button is checked.
Eg:
CODE:
The second groupbox does not appear and is directly behind the first groupbox. The Top code doesn't seem to be working either.
I'm stuck on a problem that I haven't been able solve. I'm making a visual basic program that communicates with an SQL-database. The problem emerged when I tried to retrieve data from the database with the help of SqlDataReader and save data from every row to a list (Customer) with the help of Add-method. It turned out that eventually the list had correct number of objects, but the information was the very same in each object of the list.
I am getting this error, Not sure why it is happening "Error The SqlParameterCollection only accepts non-null SqlParameter type objects, not Int32 objects."I have tried with all sorts of possibilties, now try to enter default data as dummy data,

I want to let the user input objects to a richtextbox 1 object on each line, and somehow use Random.Next to select pseudorandomly a few objects, the number 'few' inputted in a textbox.

I have a user control that inherits the FW ListView and I need to dispose of two objects when the form's disposing of it's objects. Here's what I've concluded already, am I on the right track?
long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.
Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).
How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.
We have a great book written for Visual Basic 2005 that we type code that is prepared in advance. We are using Visual Basic Express 2008 and normally this works really great; type the code run the program and it works, however I am running into a snag.
The textbook shows the following code: IN THE(General) (Declarations)AREA we are told to type the following:
' Create a Graphic object to use with the game's bitmap Dim myGraphicObject As Graphics = Me.CreateGraphics ' Create an empty Bitmap Object
[Code].....
is there a difference between VB 2005 and VB 2008 that would be causing the errors? or am I missing something subtle maybe mistyped?
I would like to know how to use the graphic methods:
-DrawString -DrawLine -FillRectangle
I am meant to use these in a method called Drawgraph in order to draw a grid and bar chart. How can I go about this? What parameters do I need to send? What variables do I need to declare?
I want to compare two objects to check if all the properites of both the object have same value or not. for this i need to use the reflection to enumarate through all the properties of an object and check the value of the property. To try the code just i have written a Employee Class having Two Properties EmployeeNo and EmployeeName. I am creating an object of the Employee class and need to write a function that can list the values of all the properties in the class.
I have just started to try learning how to use Visual Basic (im running the 2008 express free version). The example im trying to get working right now looks like follows[code]...
I am programming a design surface where I add Image objects to the surface when an image is added it calls the draw objects command. It works fine I would like to figure out how to covert the object to an image to save it? Below is the draw sub used to draw objects onto the surface:
Public Sub DrawObjects(ByVal g As Graphics, ByVal Scale As Single) Dim drawObj As GraphicObject Dim i As Integer
I am working with a graphics program in VB to move an image around the Form. I'm trying to create barriers that cannot be crossed. At first, I tried to represent this with a 2D array, but this proved too complicated. For now, I'm trying to create a series of rectangles. What I want to happen is when the point the image is anchored at intercepts one of these rectangles, it will either be prevented from moving or sent back to where it was directly before the image moved. I know there is an intercept command, but I've been unable to figure out how to use it in this content. The code I have is below.
Public Class Form1 Dim PlayerSprite As Image Dim BGImage As Image
[code]....
As I said, this is to create a graphic barrier. However, I expect to make a number of these Rectangles?
i would like to be able to erase a graphic that was created.I would like to not have to redraw the graphics minus the graphic thats unwanted.Is there a way to delete a graphic?
