Moving .NET Controls At Runtime?
Jun 4, 2010
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 code which I think ought to work well for this, however it seems that Me.Controls is empty at runtime, so my for each loop is never entered. Could someone please offer a suggestion as to how I can move the controls?
Private Sub uxMenuStrip_VisibleChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles uxMenuStrip.VisibleChanged
For Each control As Control In Me.Controls
If control.Name <> "uxMenuStrip" Then
[code]....

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?

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?

I'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 am using the following code to move a label at runtime when I mousedown on it and drag it, but how can I make it move freely and randomly around the form without any human intervention?
Private Sub label2_Mousedown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Label2.MouseDownIf e.Button = Windows.Forms.MouseButtons.Left Then

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.

When I place a control on a form and need to move it, it becomes invisible when I click the mouse to move . What did I accidently change? I use to be able to see it before.

I know this is probably not going to be simple, I tried searching around, but couldn't find anything. I am using some code to 'draw' text in a custom format to a panel with a custom bitmapped region (custom shape).Here is the code that writes the text inside a specified area:
g = LeftControlPanelV2.Panel1.CreateGraphics
Using fnt As New Font(New FontFamily("Arial"), 9, FontStyle.Regular, GraphicsUnit.Point)
Dim sf As StringFormat = StringFormat.GenericDefault
sf.Trimming = StringTrimming.EllipsisWord
[code]....
Obviously the text is not really located on the panel, but looks like it as it's drawn on top of the panel. So, when the panel or form that the panel is attached to moves, I lose the text. I though I could just call back to writing the text when the panel/form arrives at the correct place, while clunky, it works to a degree. I was hoping there was a better way of doing this, so that the text doesn't disappear when moving controls and I don't have to make repeated calls to the same drawing text over and over and over...
Edit: Should probably add that there will be 5 different panels each with their own custom drawn text, and all 5 need to move at the same time...

I have a lot of forms set up, probably about 10-15 so far (more to come). Some forms 'lay' on top of other forms, and each form contains multiple controls. I am discovering that my approach is not very likely to succeed in what I am thinking of doing.
Here is one example: LeftControlPanel form contains 5 controls, but 5 other forms 'lay' on top of it and use transparencies to load up bitmaps. Since I cannot parent the forms that 'lay' on top of the form, I cannot figure out a good way to move them.Is it logical that when I move LeftControlPanel to a different x location, I would just move all the forms that 'lay' on top of them as well?Seems like a clunky approach of moving one form since parenting the transparency forms will remove all the transparencies that are set up...
Is there a bit better logic I might be missing, or bite the bullet and start moving multiple forms at once?

I'm working on a .Net Windows application. All the controls arrange fine, but when the user specifies their Windows display text to be larger than the Windows 7 default of 'Smaller', the controls get moved around on the form and makes it unusable.
Is there a way to lock down those controls no matter what the display text setting is at?

I could review that could help me create a designer view (actually similar to how Visual Studio works but more basic), I would like to be able to add controls dynamically (just panels or images), then move those around individually(drag and drop), then count them all and get an array of what I have added..[code]But I would like to get an idea how it looks if things get more complicated..I wonder, are we able to use the classes of Visual Studio's editor in some way? Or are there .NEt classses that can do this?

I have a winform with a main panel that is anchored top, left; dock: fill, and set to a specific size to contain another panel of content that we want to scroll through. The other panel along with a few other controls are on the main panel. Now, for some reason, after running the application the controls will be shifted down (never horizontally) some random amount. Now, the "random amount" may in fact be the last position of the scroll bar or something, but either way, it is unintended functionality. I have resorted to automatically resetting the locations of these controls on the main form in the constructor?

"add controls at runtime" how to add code to the controls. kinda useless with no code, ehh? all results only told me how to add the control, that's it. well, this result is different. i will teach you firstly how to add controls at runtime, then how to apply code to them at runtime
Firstly, add the controls:
[CODE]..............
Now run it. do you have a button on the form? if yes, excellent. if not, you made a mistake. try again now how to add code? you may have noticed that when you double click on any control, it says private sub button1_click(blah, blah, blah) Handles button1.click where it says handles button1.click is what determines when the code executes under what event for what control (in this case the click event for the button1). this won't work when adding code at runtime. did you notice in the above example i added a with event, and addHandler? this is what creates the handler (same as Handles button1.click)
Now we add the code for the runtime control
[CODE].........
Above, the addressOf button1_click tells the program to execute the sub button1_click when the button is clicked on (as determined by .click) but i know what you're thinking! your thinking "why would we even BOTHER doing this at runtime? isn't it easier to do it at design-time in the first place?" yes it is, providing your not writing a plugin. plugins are code based, not GUI (also reffered to as WYSIWYG). to update existing forms using plugins, you need to use this method.

I did something that when I now load my program(VB 2008), my controls; combo boxes, buttons, progress bar, etc. look like they are from VB 2005 or like VBA buttons, not the rounded edge buttons of 2008.
They look like vb 2008 controls while I am in design view, but then they change their style when I run the program..

I was wondering if there was a way to dispose a control that i generated at runtime in a diffrent block of code, The reason why i can't dispose of the control in the same block of code is that the controls settings depend on what the user imputs. For example if i generate the control on a timer tick the code would look like this,

In the helpfiles of Visual Studio 2008 I read control arrays are no longer supported. There is an example for the new situation but then you need to hard code the names of all the controls beforehand.I do not know how many controls I need, could be one or 5000 (think simple image browser). Is it still possible to create something like that or should I change to a different programming language like Phyton? At the moment I work around it by using a browser control and then manipulate the <img> tags but I'm puzzeld as to why this functionality was removed and if there's a solution to the problem.Another thing I don't understand is where the app goes when it's installed with 'Click once'. It dissappears completely, doesn't show up in 'Program Files', can not be found by the search function but it *is* somewhere because you can start it form the Start menu. However, I use data which is in a subfolder of the program folder, which I nor my program can find any more after the app is installed. The program runs but it can't find any place to put/get its data so in the end it doesn't work.
I work around it by *not* installing the program but have people just run it after unpacking the downloaded folder. This works great but I wonder how long this will be the case until Microsoft disables this possibility? I have no idea why they would, but I also have no idea why they did remove the functionality I mentioned above. I already changed to PHP and MySQL because I had to throw away my carefully built W2K+MSAccess image database a few years ago and after installing Vista Visual Studio 2005 was a goner. OK, I upgraded but then no control arrays any more and now they hide the apps when you install them? Why on earth would they do that?

How do you position controls loaded at runtime to align middle? I'm not looking to match the x y coordinates as the heights vary.
For example loading 2 text boxs and 2 labels.
I've tried using the Anchor and Dock properties but with no joy.
e.g.
txtNewTextBox = New TextBox
txtNewTextBox.Name = "name"
txtNewTextBox.Dock = DockStyle.Fill
