I'm trying to create a grid usercontrol.This means that when i press "UP" it goes to the cell above (...so on for all directions) tab goes to the right and enter goes down.Now all these keys (excluding enter) change control focus so i've got a problem using them.How can i lock focus on the control so that these keys won't change it and so that i can use these keys for other things?
View 5 RepliesA form's key events will fire when you press a key. Place a control on that form and it won't happen any more because that control has focus. There are exceptions to this however as you will see if you place just a h or v scrollbar on the form. The key event will fire because the scrollbars can't receive focus as is demonstrated by the following
Private Sub ScrollBar1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles VScrollBar1.GotFocus
Debug.Print("Scroll GF")
End Sub
[code]....
So I've made my own special scrollbar usercontrol and i can't figure out how to have it leave the key events alone. I'm pretty sure that the problem is that my usercontrol can receive focus at the moment.
I found that the way of doing this is "SetStyle(Windows.Forms.ControlStyles.Selectable, False)". I put that in the new event of my usercontrol and now it looks like this:
Public Sub New()
' This call is required by the designer.
InitializeComponent()
I have a custom UserControl that contains just one TextBox. When I set the control to Enabled = False, the TextBox is disabled but the control is not (control still fires the Enter event).
How do I ensure that the UserControl will not receive focus?My Enabled Property Looks like this:
Private _Enabled As Boolean = True
Public Shadows Property Enabled As Boolean
Get
Return _Enabled
End Get

In Visual Basic 6, locking a control would prevent the user from selecting a control without greying it out like disabling it would. Is there a way of doing this in Visual Basic 2010?
View 9 RepliesI just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.

how do you control USERCONTROL button1_click event from form's button2_click event?
button 1 = hidden button on usercontrol1
button2 = visible button on form1
form1.button2 should click usercontrol.button1

View 1 Repliesi'm an old VB6 programmer that has just starting dabbling in VB.NET 2010 and my first project is a Usercontrol Button project and i'm running into some trouble with refreshing the usercontrol on events.
For example when you mousedown on the usercontrol i want it to act as if the button is being pressed in, to do this i make the caption move 2 pixels down and to the left. And then reverse this when the usercontrol mouseup is triggered.I think my code is correct but i'm not 100% sure what i'm doing with me.refresh and the usercontrol_paint events.

I have a Windows Form frmMain() holding seven more-or-less unrelated UserControls, ucFlopsy", "ucMopsy", "ucCottontail", etc...I say "more-or-less" because each of the seven UC has three similar public read/write properties:
IsLocked (a boolean indicating if the following two properties are "Locked")
IsLockedID (if IsLocked=True then IsLockedID is an integer)
IsLockedName (if IsLocked=True then IsLockedName is a string)

After adding a UserControl to a form which access my database I get this warning:
Warning1The database file cannot be found. Check the path to the database.
[ Data Source = C:Program Files (x86)Microsoft Visual Studio 10.0Common7IDEDatabase.sdf ]
C:UsersUserDocumentsVisual Studio 2010ProjectsProject1Project1Options.Designer.vb2160
Thing is I never had a database at that location, my database is and has always been in MyDocuments in the Project folder itself. There is nothing anywhere in my code referring to that database! When I double click it I get sent to this line in the Designers window:
Me.Controls.Add(Me.BoxControl1)
Even though I get this error I can still access my database, so basically it does absolutely nothing except drive me mad! So how do I fix this?
I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName"
Dim MyControlType = "TextBox"
Dim MyStringValue as String

I have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control. If I create a reference to the usercontrol form the second form within the usercontrol I get a new instance of a user control. All I want to do is set the property on the usercontrol and close the secondary form. How do I reference the usercontrol from the form within the usercontrol?
Code in UserControl:
Public Property DBItems() As List(Of String)
Get
Return DBItems

So, I know from the user32 dll, and I set that as focused.
Is there a easy way of determining if the app has focus?
im using send keys, and i dont want it typing the keys and such, if the app doesnt have focus.
Also, if you click off of it, etc... It's more so a pause thing...
The only other way I can think of, is setting it so,
If myapp has focus, then pause the keysends.... then if it loses focus, assume the app i want has focus again.

View 1 RepliesI have an application that just stores shortcuts to most used applications on users desktops. My problem is that when the machine loads after they login the app window looses focus and sometimes doesn't show in the taskbar. I tried to use Me.Focus() but that just gives the treeview focus and not the form itself. I mean the parent has focus in the treeview but the form is not highlighted, I can then click on the form and it gets selected.
What is a good way to get the whole form focus? I used me.focus in the form load too.

Does anyone know if you can remove focus from all controls on a form so a user doesn't inadvertently cause action on a control when it's unintended such as hitting Enter at the same time your app appears causing some action to occur? Do you have to leave focus on at least one control?
View 12 RepliesI have a form with 3 controls that have TabIndex values set:Combo box (cboPostpone) - TabIndex = 0 Postpone Button - TabIndex = 1 Install Now button - TabIndex = 2
The code below is part of the Timer1.Tick event The code below seems to change the focus but then when trying to tab through the controls, it stays on the combo box.
[Code]...
Lastly, I removed cboPostpone.Focus() command from the Timer1.Tick event and move it to the Postpone button Click event. I run the focus command right after the me.hide command. I delayed it the first time and it came back with the Postpone button in focus again instead of the combo box.
Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

Here is what I've done:1) Created an Excel COM add-in for Excel 20032) Added a NotifyIcon to the Windows taskbar notification area (aka system tray) during ThisAddIn_Startup3) Added a ContextMenuStrip with a ToolStripButton to the NotifyIconWhy is it when I right click on the NotifyIcon, Excel gains focus? If after clicking on the NotifyIcon to display the ContextMenuStrip I choose not select an option on the ContextMenuStrip and instead click back on the Excel window, I get a weird flashing cell in Excel.I've created a video of the problem to help you see what I [url] anyone know how to prevent this? Ideally, I'd like to be able to click back on Excel and only have the ContextMenuStrip close and Excel regain focus.
