I am working on a project that I want to allow the user to move and resize controls in a panel container at runtime, much like the developer can do in the IDE.Is there a mode (not sure its the right term) I can implement on a selected control that will show the grab handles and allow moving and such?

I am attempting to move all controls on a form down or up by the height of a menubar depending on whether it is visible or not.

I have a picture box that i want the user to be able to move at runtime of course....he will click on the picture and while clicking the mouse down he can move the picture and when he release the mouse the picture stays at the location ....i searched the net and did not find any usefull articles ..
View 2 RepliesI'm creating an application in visual basic, basically a part of it is where I hope to achieve the function whereby users can move pictureboxs(images) when visual basic is running.
Basically, i've got several picture boxes that obviously cannot be moved around the form at the minute.
For example, i want to be able the user to be able to move picturebox1 around the form when they click on it and move it where they want to as opposed to what it does now - doesnt move.
i'm attempting to develop a calendar using datagridview where column headers are dates and row headers are list of employees.
i would like to add a button/custom control on the datagridview to represent a task over time where I can move or resize at runtime.
At design time in the IDE, you can ctrl-click or drag a box around multiple controls on a form and move them all at once. How do you do that at runtime. I need to be able to create image maps based on textual copies of medical claim forms that are generated from different systems and the ability to create dynamic label controls and move a single or multiple controls and resize is required. How does MS do this in the IDE?

1. I have created a moving object (which is a button) in a form (rectangle box) called "Enjoy Button" and it moves when
2. A specific button named "Start Timer" is pressed...When the "Start Timer" button is pressed,
3. The "xTimer" event is called and the button moves in a rectangle box and bounces of the walls...=animation
4. However, i need to write a For..Next Loop in the
5. "For Next " Button= a button named for next
6. And also put a counter in the loop to control the animation time..
7. The loop should stop at a certain time, and the object too should stop at that time,at a new location
This is what I have so far
Private Sub ForNextButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xForNextButton.Click, xTimer.Tick

Counter = 1000
For Counter = 0 To 1000
xTimer.Enabled = MyTime * 1
' Move the button for a set amount of time
' Exit the loop

I'm trying to make a picturebox move left by 5 pixels when i press the left key. I am completely lost right now to be honest, and I've been trying to figure this out for the last 4 hours. I haven't done VB in two years, so feel free to crucify me on my mistakes, I learn better that way.[code]One thing I am wondering, is if I have to hardcode the picture box into my form?
View 2 RepliesI am creating a game where on clicking the start button the object below it moves across the screen a bit further with each click of the button. I used VB at college way back in 2003 and am extremely rusty. I am guessing I have to change the X value of the Location property to make the Picture Box move horizontally across the screen, however I have had no luck so far!

Trying to write a very simple game moving PictureBox2 around with keys and when it passes over another object such as PictureBox1 the score is incremented and then PictureBox1 is disabled/removed. Problem is that it disappears but every time you pass over that area it still increments the score further as if the object was there still.
Here is current code, but have also tried hide, dispose and Controls.remove with no luck.
If PictureBox2.Bounds.IntersectsWith(PictureBox1.Bounds) Then
score = score + 1
Label1.Text = score
PictureBox1.Enabled = False
PictureBox1.Visible = False

Problem:I am not getting the cursor (4 arrowheads) for moving the form.I am using the Panel1_MouseHover to display the cursor. Right now if I choose any other cursor then it is working but the same cursor also displays when I hover the mouse over any other control. I want the cursor to show only in the areas of the Panel where there are no controls.How do I show Tooltips for the images? The play,stop,next, previous,playlist,Hideme(with the smiley),volume are all images and not buttons?
I've trying to get the runtime path of an OLE Object stored in a database. The code below is used to get the Ole Object (In this case a PDF document).
[code]...
Currently, all that's being returned is a pile of bytes of which I have no clue of how to handle.I need to somehow find the path at runtime of this PDF file in order to use it as the value of the 'src' property (string) for my Adobe Reader control.
I get this error in this code:
Private Sub Request_Stuff_button_Click()
Call Main.createObjects
Call My_Control.requestStuff
End Sub
at the 'Call My_Control.requestStuff' line.The 'Main' module looks like this:Public My_Control As ControlObject
[Code]...
right before the line that gets me the error, x gets the correct value right before the error happens which means My_Control is definitely an object and is definitely not nothing.
I have an object, o, and a type, T. I'd like to use reflection to change object o to type T at runtime without instantiating it.The equivalent at compile time would be:
Dim p as Point = Nothing I know how to use Activator.CreateInstance to create an instance at run time that is equivalent to: Dim p as New Point()
But i don't want to do this. I have no knowledge of the type's constructor parameters and some types don't have a parameterless constructor. eg. Font. So, to sum up, I'd like a way of performing the equivalent of: Dim o as T = Nothing
In case you're wondering why I'm doing this, it's because I'm using a PropertyGrid on a form to edit types. If this is the first time for editing, say, a Font, then passing an uninitialised Font to the PropertyGrid makes the grid display the default values.
I tried 'o = GetUninitializedObject(T)', but the PropertyGrid either wants a properly initialised object or an object, with a defined type, set to nothing.
I've actually solved my particular problem here: how-to-use-the-property-grid-in-a-form-to-edit-any-type
, but i'd still be interested to know how to assign a type at run-time without the use of a wrapper class (which I was lucky enough to be using).
I am developing a fairly large database in VB 2010 as a record keeping. There are 37 tables with some many-to-many relationships in there and some collections too but it all gets loaded into a List of Person object.It is a record keeping database for a youth charity including Personal data, lists of events attended, Medical data, Duke of Edinburgh (UK award scheme) etc The main form is a tabbed form with the linked data from other tables and collection on various tabs
Is it possible to bind a runtime object to a control? if it is possible my life becomes very simple.I can get basic data working with DataSet binding and navigation but the ralationships may prove too fiddly to link as datasets.
Is it possible to construct the name of an object (in this case, a Panel control) at runtime?
What I want to do is change the Backcolor of one Panel that is a member of about fifty panels. I can get the string of the name from the Sender in a RadioButton CheckedChanged event. So what I want to do is something like:
PanelName = sender.parent.name & ".BackColor"
PanelName = Color.Red
(I realize that the syntax above is invalid. I'm just using it to try to get the idea across.)
I can do what I need with big, fifty-element Select Case blocks, but the code is so repetitive that I was hoping there was a more elegant way.
Trying to create an application where the objects in a form are created during Form.Load depending on the content in an ini-file.The objects I have in mind are textboxes and labels for a start.
View 5 RepliesI want to create a new object of a class which is not predetermined before run-time. Something along the lines of:

'btnOrder.Location = New Point(300, vertloc + 20)
'btnOrder.Text = "Order"
'btnOrder.Name = intCount.ToString & "OrderButton"
So I have my program make buttons similar to the above, I'm going to have a button created at the point were the cursor is, as long as the location is a valid one. Now I have two questions.
1) I want to use the following code to be able to move around any of the new buttons that I place down on the form.

2) I also want to be able to change the back color of the button based on a number of boolean flags I will be setting. Is any of this possible without completely mangling things? I'm hoping there are some easy options for setting a button made on runtime to use a number of premade subs or functions.
On a side note: This does not need to be exclusively a button. a picturebox or a text box would probably work just as well for what I want to do, but I like the look I can get with the button atm.

As you can see, i can retrieve the tag of the button (which is created at runtime) without any problems, i've made a temporary msgbox to show me the value of the tag, just for testing purposes. What i do have a problem with, is retrieving the tag of the individual web browsers, how should i do this?
Next issue, how would i code for my buttons to show the web browser with the same tag as the button that's just been clicked?

Slots is the same again, breaking down to another ArrayList with more details.
