I've made my first little custom control. It is a textbox, then next to it a picture. I've written the code already for the picture box. It basically opens up a new form with a listview on it that displays details from the database. But now, I still want the text box to have the basic properties of a normal textbox like text alignment, enabled, backcolor, etc. But not sure how to do this.

I'm using a recursive search to find all of the controls on my form and then do something with those controls once I find them.This is the basic layout:

----------PanelChild

I am using Visual Studio 2005, Version 2. I am coding a Windows Application in VB.NETI am coding one particular form for an Emergency Reponse Information System (for varsity)On my form, I have three textboxes (one of which must be filled in) and below them I have a datagrid. I want the user to fill in one of the boxes and then click a Search button. These textboxes correspond to different column names in the same table. There is a Location textbox, an EmergencyResponseID textbox and a Name textbox. So if the person types in a location "Washington", then I want all the Emergencies that have happened in Washington to appear below in the datagrid.

I want to add a custom property to a button in window form. Currently i am using following code to create my logic. but i want to create an enum value for a button control.
btnPartyDetails.Text = "View";
{}
btnPartyDetails.Text = "Add";

I want to do something like this, where ActionType will be my enum.
I also want to create custom event based on the value set. How can i do this ?
I've created a user control with a simple text box and a corresponding label and added a few custom control properties. When added to a form, I'm trying to loop through all control of this type and evaluate the custom property. In the below, the cntl.MyCustomProperty is not recognized. I can evaluate the property when I check each user control on the form by name, but not by using the loop below. I would much rather use the loop as it is much cleaner.
For Each cntl As Control In Me.Controls
If (TypeOf cntl Is MyUserControl) And cntl.MyCustomProperty = "ABC" Then
''Do some stuff
End If

I need a multiline TextBox which is always disabled, but it shouldn't paint itself in gray, but I want to keep its designer choosen color. I previously had the same requirement with an always-black Label (no multiline) and so I inherited from Label like:
Imports System.ComponentModel
Public Class LabelDisabled
Inherits Label
Sub New()
InitializeComponent()
Enabled = False
End Sub
[Code] .....
But this way, neither I can set the "real" Enabled property, I mean the backing field.
I'm trying to make a Lottery program on visual basic 2008, but there's one thing that I am stuck with.Note: My explanation may be hard to understand, so if you would rather have me send you my code and see how it works, I'm fine with that. My code is pretty long so far, so I didn't know if i should post it on here.
My program has 6 picture boxes lined up horizontally, and has one text box underneath each one. There is a play and stop button on the bottom left corner.I've altered my program to have animations for the picture boxes. Instead of having a random picture picked, I have it so that each picture box scrolls through a series of 10 numbers when the user presses play.
When the player presses stop, the picture boxes stops scrolling, and random pictures are displayed in each box. (The picture is really just a black circle with a number in it).The text boxes below the picture boxes are for the user to put numbers in. These are the numbers they select for the lottery. Now this is my predicament. Since the picture boxes decides what the winning lotto numbers are, how can I compare the numbers in the text box to the pictures?

In THIS Thread:NickThissen Said:Quote:It will appear in the toolbox even if you put it in the current project, instead of a control library project.No, it does not have to be in a control library, nor does it have to be a UserControl, to appear in the Toolbox. Any class inheriting (either directly or indirectly) from Control or Component will appear in the Toolbox. Since RadioButton inherits from Control, and your control inherits from RadioButton, your control inherits from Control too, so it will appear in the Toolbox. I have successfully created a pretty cool custom control. I Built the project and have added the a reference to the .dll form a new Windows forms project. It works great, as long as I do something like THIS:
Dim ThisControl As New MyCustomControl
ThisControl.Top = 40
ThisCOntrol.Left = 40
[code]....
I have the above control I am using, whose base class is the ListBox.Unlike the ListBox, it doesn't highlight a new item when it is inserted.I already had to add the ability to InsertAt() a new item since the person who made it originally hadn't implemented that part.But, I am having trouble figuring out how to make that part work.The above link is directly to the original Control.Here is the code for the Insert method I added:
Public Sub Insert(ByVal index As Integer, ByVal value As MCListBoxItem)
Try
List.Insert(index, value)

I have several custom controls inside my project, just added a new class and then inherit the original control. For example i have a Custom DataGridView Control (CustDGV), that defines several properties in the constructor of the control.Now i have one problem and one issue, the problem, if i change the CustDGV i don't know why, the forms that are using the control doesn't update the changes... The only way it's removing and adding it again.. not very useful when i have several event's already defined for the dgv.How do i force the form to update the control?The issue it's that some of the properties doesn't get applied, for example i set the column header height and the disable resizing in the constructor, but if i run the code this two properties doesn't get applied, i need to define them in the form where i use the control to get the results that i expect..The order of the properties in the constructor? The properties in the properties window override the constructor ones?
View 17 RepliesI have a custom control I've created, and I'd like to be able to step through it (either in a test application or the one it's being used in). Is there a way to do this?
View 1 RepliesI have a panel that has 9 pictures boxes within it. I need the User to be able to create as many instances of this control as they like.
Then each control needs to be able to move freely within the form.
I've created the control and added the appropriate code to move it around the control.
I've made the control canvas the same size of the panel. The problem is that when I move the panel, it only moves within the bounds of the control canvas. I guess I could increase the size of the canvas, but then additional controls would still only be able to move within their bounds and it would come out all wrong.
Is there anything I could do about this? Or is there a better method?
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.

View 8 Repliesis there a way to make a textbox searchable like those Ctrl + F which can be found in most of the windows application?
I have googled and found some functions which is quite similar, but I have an issue which for eg.
My multiline textbox contains a lot of text with scrollbar, somehow the text I want to find is in the middle, when I click the find button, the word is indeed found and highlight, but the scrollbar still remain on top.
I wonder how can I make the find adjust the scrollbar as well?
I have created a custom control in one VS project. Once tested and built, I then copied the object over to a structured class library type project I hope to use as a code repository for these kind of things. To ensure I can get to the control, I created a test project and added this repository dll as a reference. The problem is that I cannot see the custom control in the toolbox.
Is there an attribute or something I should've used in the repository dll in order for this to happen?
My objective is to create a custom namespace in this repository dll so that any custom objects or controls can be referenced in various other applications without having to copy the objects to each. I know my reference is good as I can create the control in code. I would just like to see it show up in the toolbox!
I created a custom control and I'm trying to insert it into a panel, but also center it.The control itself is larger than the panel, so I've set the AutoScroll property of the panel to True. I think that might be affecting it. Perhaps I should just offset the Y axis a bit.But, either way, this is what I'm trying:
VB .NET
'Create the control
Dim AutomationReport As New AutomationReportControl
[code]....
It works just fine with the X axis, but the control is out of bounds vertically. About 1-2 inches of the top is cut off.
I did try to build a custom control but unfortunately i couldn't make it work due to lack of knowledge.I wanted to build an custom itemlist that allowed me to add 2 or 3 icons beneath it with labels associated.
