Scrollbar On Custom Control (inherited From Windows.form)?
May 16, 2011
I'm trying to create my own control to build a custom planning on it.After trying it with loose controls I got an error but after advice on my previous post, I redraw everything.I have now the header of the control finished, the header shows the days of the month for as many months that fit in the window.Now I want to put the list of data below it, but it will be more than the windows height, so I need to have a scroll bar that will scroll the data but not the header.I would not like to design my own scrollbar and rather use the scrollbar control for it, but when I put it in, I cannot use the NEW keyword.example:
Dim sb
As
ScrollBar
with this I get the error message: 'New' cannot be used on a class that is declared 'MustInherit'.How can I get a scrollbar on my form to scroll the list only (so not the header)?

I am creating an Extended DateTime picker. I have created a Class the inherits the Default DateTimePicker and Adds a new Property NullableValue. I have placed the control on a form and bound it to a Binding Source using the NullableValue Property. When I load the record the control updates as it should. But when I change the value and save it does not save back to the database.

I moved this from the debugger thread as I got no responses.This may be a better area.I have a problem enabling a Scrollbar on a custom control I have created.The custom control has one component,the scrollbar and an area that I draw upon from an internal datasource.Think something like a textbox.In certain instances,I want the scrollbar to be enabled. The Custom Control's job is to do this when the situtation is appropriate.I have a very simple piece of code here:
If <logic conditions> Then
DataScroll_vscrollbar.Enabled = False
Else[code].....
This code is in my OnPaint routine (along with a bunch of other drawing related stuff).Essentially I've determined that there is more stuff to display than the area of the control and need to turn on the scrollbar to give the user of the control the ability to see later stuff.With the exception of this funny behavior, the control is doing exactly what I want.I step through this and have a watch set.I can step through the set to True, but the Enabled value doesn't change.Even the EnabledChanged event fires (Doesn't on the set to False because it's already False), but the Enabled value is still False.I don't know why.Now here is the really interesting part and may give somebody an idea about what's happening: I can change the Enabled value via the debugger (via the Watch) to True.The EventChanged will fire, and from that point on I can set the Enabled value to either True or False and back again with no problems.
I even did some really crazy testing to see if perhaps the debugger just wasn't showing something.
did something like:
Dim idiot as boolean = false
if <logic> then
idiot = true[code]....
I have set the values to Minimum and Maximum, but the problem remains.

I created a custom user control named "XYZ" and It is avaialble at the toolbox menu in the design mode and I can drag and drop it to a vb.net Windows form. What I really want is to dynamically to add this user control to the Windows form during the Windows form load event. Actually I want to add this user control to a "split container" named "sc_1" on the tab page named "tp_1" on a tab control named "tc_1" on a Windows form. What is teh vb code to add a user control to a Windows form. I am using vs 2005 and dotnetwork v2.0.

In my Windows Form application, i want to change the width of a scrollbar that belongs to a FlowLayoutPanel.
The Scrollbar is added "automatically" since the content of the Flow Layout Panel is larger the Form.
From what I've found on the web, it seems to be tricky.

I have a base form and I inherit other forms from it. However, if i go back and change say the size of the base form, I don't see those changes take effect in my inherited forms. Does anyone know why that is? Is there a solution to this issue?So as far as design is goes, what exactly gets inherited by other forms?

I am making some changes to a fairly old project.It has a DataGrid with an Inherited Class
Public Class CustomDataGridTextBox
Inherits DataGridTextBoxColumn
and a Override Sub Protected Overloads Overrides Sub Paint (.......What it was doing was alternating the Data Grid Line colours New Requirement is to break up some items in the DataGrid By categories So I have added new lines to the data and sorted so they show up ad category headers (Production Stations) And they would like the Category Header to be a different colour and then the alternating line colours to restart.This did not sound too difficult but that has proven a trap Setting the category header is no problem but restarting the alternating colours is Previously the row was determined to be odd or even to set the colour.Now I am intending to use an Integer to define what colour is used but it persists only for that text box.
How can I get it to extend its life so each call can refer to it and update it and set the desired colour?All I need to do is have an integer variable that will hold its value for the next call?

I have to design a custom "log grid" control to use in another of my projects.Up front, I am new to vb.net 2008. I have used VB6 for years and I am trying to learn how to resove the differences as I go. But I need help.
This log grid contains 96 columns and 4 rows.I tried using the TableLayoutPanel and a Panel per cell but found the control to slow to paint. That's 384 discreet controls.I am now trying a usercontrol with a panel and GDI+ to create the grid. I've created a collection for the columns and a collection for the rows. So far so good. My mouse clicks raise the correct events per cell.
I now need to indicate which column the mouse is over. This is the problem. The column must be highlighted by a vertical bar from the top of the column to the bottom. It must also be transparent. I need to see the gridlines under the highlight. I've tried using region using the following code. (myRegion is declared Private MyRegion as Region at module level for persistance)

I have been scouring for examples to give me some idea on what I need to do to create a skinable scrollbar. The only thing close that seems to work like I need is Cool Scrollbar The problem I am running into is on the designer...when I move it, resize it, or change the direction of the control (ScrollbarLayout), it seems to want to re-name the class the item is an object of from CBar to cbar.CBar. Once I position and align it properly to check, I can go through the Form1.Designer and simply remove the cbar. and get no errors. When I run the program, it is fine, so this is telling me that there is something wrong with the movement in the class...

I've search the net in order to create a custom control but nothing I find is worth looking at, The main thing I want to do is create a skinengin via DLL and import it in my vb 2010 then using or creating some sort of skin builder where I can create a full setting file which contains all the details of the customization regarding the Form(Look, Feel and the controls such as a menu), I have used Iriskin and multiple apps doing this for me and when a user installs my application they still recieve a message about buying the registered DLL file, I would like to create it completely from scratch.

This relates to WPF but is broad enough that a winform answer will do. I have made a few custom controls in the past by inheriting from whatever particular control I wish to inherent from.
I have noticed that I can add a form to a class/user control library from the add new dialog and have it run. When this application is compiled I get a DLL.
So my question is can I use a Form as a custom control. The reason I ask is I am creating a more advanced MsgBox for a new application I require and a form as its container makes the most sense.

I'm working on a project which must run on several computers, each with their own version of windows.
In Windows XP the project runs fine, but in Windows 7 I get a horizontal aswell a vertical scrollbar. I can't seem to turn it of.
I'm using a MDI parent and several childforms, eacht childform neatly adjusted in size to fit the parent, not exeeding the parent limits.
autoscroll is false
windowstate normal
Am I missing something, or is this just a supurb item in wondows 7?

I have created a custom control that is included in a control library that is referenced by a VB Forms application.
When I modify the control, and have the application open in a VS window, VS usually asks me if I want to reload items that have changed.
However, a couple of times, it has not asked me this, and when I go to open the form that contains the modified control, I get an error window warning me that if I ignore the error message and continue, then I risk making VS unstable. I've learned to ignore this error message, continue, and immediately save the form to a new file.

I am trying to figure out how to generate code from user input. In Visual Studio 2008, Visual Basic.My script always begins with:function Init (Quest)Then from here a user would input a quest name, type and zone in a interface using windows forms.[code]I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.Is there anyone that can explain how I would go about doing this. Or maybe some kind of visual studio plugin that will help me out.

How to generate code from user input. In Visual Studio 2008, Visual Basic. My script always begins with:
Code:
function Init(Quest)
Then from here a user would input a quest name, type and zone in a interface using windows forms.
Ex:
Code:
RegisterQuest(Quest, "Kill Zombies", "Heritage", "Firestorm")
end
This part a user would enter in his interface what would an NPC say if accepted.
[Code] .....
What I need is a few text boxs that a user can input "Kill Zombies" or whatever they like and when they push a generate button it will create a file with a .quest extension. All of the code remains the same except for the quotes that would be the user input from the interface. Basically everything in quotes can be changed by the user in an interface. I have created my own functions for when a user accepts, deny and complete a quest. The user just needs to input what should happen then click a generate button to throw it all together as a .quest file to be saved in his or her quest folder for the server to call on later.
I also have many other functions like:
AddQuestRewardFaction --- (Quest, Faction ID, Amount)
AddQuestRewardCoin --- (Quest, Copper, Silver, Gold, Plat)
AddQuestStepObtainItem --- (Quest, Step ID, Description, Quantity, Percentage, TaskGroupText, Item ID(s))
Etc
I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.

I'm coming over from VB6 in which you could use 'user controls' to create reusuable custom controls. They were simple and contained and you can easily create several instances of a user control within the same or other apps. In vb2008 there are user controls but I can not figure out how to add them to forms or or other apps. Can someone please give me the the basic steps to add a custom user control to a form or project.

When I try to create an Inherited User Control everything goes fine until I specify the base control and press "Add" in the Inheritance dialog. The code in the newly created Control should have a "Inherited From" statement, but it doesn't and nothing works after that. I even tried following the ctlClocklib project and the same thing happened. ctlAlarmClock.vb was created but the "Inherited From" statement was missing.

Having some issues with creating a simple control in vb.net.
I create a control with a single label in, I don't change anything except the colour of the control and the label and also making the label anchor to the edges ( with a small border around the edge)
When i then build it and add this control to a form. Some of the edges are cut off and it isn't anchored the way it was in the control.[url]...
as you can see in the second image the control has lost its white border at the right and bottom.
