VS 2008 - Draggable Control And AutoScroll - Allow Moving A Control On A Form At Run-time
Dec 26, 2009The following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

User Resizable TextBox?

View 2 RepliesDataGridView - New Columns To Be Resizable By User?
Jun 10, 2011Recently I was working on a project that included several DataGridView objects. With one, I dynamically create columns based on the types of data being displayed. I established a baseline size (so each column would initially display the same width), and a minimum size. AutoSizeMode was set to None. I knew that I wanted the new column to be resizable by the user, so I put in code to that effect:
Resizable = True
When I tested the code, the columns were not resizable. I traced the code, looking for anything that would reset the property Resizable to False. Nothing. I commented out the line with the
Resizable = True command;
The columns were resizable after this. At this point, I remembered that Resizable is defaulted to true. But I still did not understand why the columns were not resizable after setting the property to True.
I did some experiments. If you create a new DatagridViewTextBoxColumn, add it to the
DatagridView, and then set the Resizable property to True, the result (via Watch) is False {2}. If you do the same, but set the Resizable property to False, the result is True {1}.
This is disturbing (and confusing) on at least two levels. The fact that the exact opposite boolean value is passed in. The fact that {2} is False. It was always my understanding that VB treated
{0} as False, and
Any other value as True.
Line Control - Resizable/Movable At Runtime?
Jun 15, 2012My project is similar to JM's Manipulating GDI+ Drawings and NickThissen's Shape Editor. I haven't used their code though, I've written my own similar code. My shapes are custom controls.
All the shapes are working fine. But I'm having trouble with line control.
1. I've tried my own line control. But to resize/move I need to write separate code. The common code that works for all other shapes is not working.
2. I've tried VB Powerpack 3 Line Control,but moving/resizing it in runtime is too much complicated. It is NOT a real control. (I guess) It is directly drawn over a "ShapeContainer" control. So, i have to write custom code for this too.

Dynamic Draggable Labels On Chart For Notation Purpose
Jul 22, 2010 I am deveolping a charting program and have a need to have dynamic draggable labels on the chart for notation purposes. Everything works fine until I try to drag a label past the 32767 (16 bit limit).
Here is the code that I drag the label with:
If ISDRAGGING = True Then 'DRAGGING LABEL
If CURRENTLABEL.Tag = 2 Then
CURRENTLABEL.Left = 0
[Code] .....
I have tried to create a new label and override the Top value with a Long Value, but it still does not do the trick. Hhere is my attempt to overload the top value to an integer.
Public Overloads Property Top() As Long
Get
Return _Top
End Get
Set(ByVal value As Long)
[Code] .....
The charts are dynamically generated from a database and represent depths. Usually at least 10000 feet are plotted at 5 pixels per foot. So some labels will be created or dragged below this 32767 line regularly. Any way to be able to drag the labels past this limit, or possible another option to be able to view these long charts.

Way To Make Resizable
Aug 2, 2011I just made a basic browser using VB... So now I am wondering how to make it resizable so that when it is resized the browser and buttons remain in same layout but the text box and browser space resize to the new screen size and the buttons do not change layout or get covered (it has buttons for back, forward, refresh, home, and stop then a text box for the url and then a go button, I want them to remain in same order but the text box to enlarge and the go button to keep to the right side of the box - and I want the browser spot to grow too).
View 2 RepliesAccess User Control Attributes From A User Control?
Mar 27, 2009I am trying to build a tournament bracket application. In order to build the application efficiently I would like to make a user control "GameControl" that represents a game and give it attributes that represent the names of the competitors "TeamNameA" and "TeamNameB" ,an attribute "Winner" to represent which team should move on, and an attribute "NextRoundGame" that assigns another instance of the user control so that it can assign the "winner" to one of the "TeamName" attributes of the next round in the competition. If the controls were native to VB I feel like I could do it easily (I have only spent about 30 hours self teaching/tutorial following) but I can't seem to find out how to pass values to custom attributes of custom user controls through code.

Resizing Controls In Resizable Windows?
Jul 24, 2009I have two DataGridView controls, with three buttons in between them vertically, in a VB 2005 form that need to be resized and moved around on a form resize.
The code below works, and does what I want. It takes the difference between the new size and the default size, splits the height difference between the two DataGridViews, and moves things around correctly.
What bugs me about it is that I've hard-coded the defaults into the ResizeEnd handler. How would I go about passing the default size so that I don't repeat myself?
Even better, is there a way to do it with anchoring, docking, and other stuff, so that I don't even need to write code?

Runtime Movable And Resizable Textboxes?
Dec 12, 2008I am trying to create TextBoxes and RichTextBoxes that can be moved and resized durig runtime as part of a program that makes/edits media-slides for online learning. The textboxes can currently be moved and resized by filling out the values for Top, Left, Height and Width on "property sheets", a method I would like to change into something a little bit more user-friendly
I created a user control with besides the TextBox or RichTextBox 3 objects to control the moving.I have currently added 3 panels to try to use for this purpose.I have written all the code to resize the TextBox when my new control is resized and when theMoveAndResizeHandles are set to be visible.The resize panels are currently 10 points x 10 points (easy to change because the 10 points are defined in a constant) and located top left above and bottom right under the textbox. The panel to resize is located next to top-left panel and has the width of the textbox - 10 pixels
My question at this point is: were Panels an appropriate choice or is there a more fitting way to do this?
-and-
Which events should I use to check for movement and resizing of the control? I would start looking into "dragging and dropping" as event, but I have as yet no idea wether this will work and what the gotcha's will be in my approach.
