View 1 RepliesI 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)

Question:Is it possible to make a userform transparent but have non-transparent controls?I notice changing the opacity of the userform will change the opacity of controls embedded on it.
View 9 RepliesI 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

I 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.
View 8 RepliesI'm trying to draw a semi-transparent layer over my entire form when certain events occur, with a prompt in front of this semi-transparent layer (similar to the effect in Windows Vista/7 with UAC enabled)At first I was trying to use a custom semi-transparent panel, but this didn't seem to work at all. As such I'm now trying to use a child form within the form using the opacity property on the form. However, when this semi-transparent form is added to the controls of the main form and displayed, it loses it's transparency.I've got a hacky work around at the moment where the semi-transparent layer isn't actually a component within the main form, and the transparency works then, but obviously this isn't ideal and could potentially cause various issues further down the line.

I am trying to develop a control that'll allow the developer to populate a collection through markup (e.g. Properties decorated with the attribute PersistenceMode(PersistenceMode.InnerProperty). I have an example from Brian Chavez that more or less does what I want but I want to have the control inherit from UserControl and not Control.Here is the code I have in vb.net:
AggregateFeeds.ascx.vb
Imports Microsoft.VisualBasic
<ParseChildren(True)>
<PersistChildren(False)>
Public Class AggregateFeeds

As it is now when I try to compile I get a compiler error that simply says object instance not set to an instance of an object on the line above. If I take it out, the page loads just fine and the Settings object reflects the values in the markup. Why am I having trouble getting the collection to populate correctly?
How to convert UserControl.vb to dll? I'am using Microsoft Visual Studio 2010 Professional
View 2 RepliesI downloaded the next project from here:

Now the project itself was built in C #, but the interesting part of me is "Toolbar.cs".
There is a way to replace the "Toolbar.cs" from C#, to VB? Or i must convert all the project? (Unfortunately, I do not know how)
I just want to build the part that I need(UserControl - "Toolbar.cs") in VB, and the rest can stay in C #, it does not matter to me.

View 1 RepliesI created a UserControl in a ClassLibrary project and then built it to generate the .dll file.

View 2 RepliesI am running through an issue for which I am unable to find a solution.My goal is to:1- compile a x64 .NET library (vb) which has a simple User Control 2- Use this dll in a .NET WinForm application targeted to x64 CPU ONLY.
I have been able to do the first step, but now I am unable to add the library into the VisualStudio Toolbox. With our previous x86 version we had just to right click to VS toolbox, click on "Choose items...", then brows to the needed x86 assembly. If we do the same selecting a x64 lib (of course I am running vs on a 64 bit OS), we get the following message "[DLL PATH] is not a Microsoft .NET module."
I've created a usercontrol in VB that handles paging more efficiently than the DataPager (at least for very large datasets). I'd like to use it in a C# project, but I've been having trouble getting it to work.I've tried simply adding PagingControl.ascx to the C# project, but when I do that the markup and VB code behind don't seem to see each other. --Is this a namespace issue?I've tried adding the PagingControl.ascx to its own VB project, then adding that project to the C# project's solution, as well as a reference. --That almost works. I can register the PagingControl usercontrol in the markup. I can access the usercontrol's properties in the code behind, but any property that involves the UI of the usercontrol fails.
Its seems as if the usercontrol's form hasn't had a chance to load by the time the C# page's Page_Load event handler fires. --Maybe this is an "order of operations" problem? At what point in the C# page's lifetime should a usercontrol's form be loaded?
Have actually managed to create a UserControl complete with buttons, windows media player ... Right-Clicking in the toolbox I browsed to the dll and that brought the control into the toolbox successfully as VideoSourceControl.I can drag/drop this control onto the form and it is fine, buttons etc looking good. Now I want to create it programmatically - I actually want to refer to an array of them.On the form load I have
Public mySources() as SourceVideoControl and I get an error saying that 'SourceVideoControl is not defined'The dll that I loaded was called VideoMixerControl.dll?

I have a usercontrol I created. I added a panel and a vertical scrollbar to the right of it. I'd like to be able to scroll it with the mousewheel. The problem is there doesn't seem to be any events that fire on mousewheel. If I take the panel off then the usercontrol has focus and it will fire on mousewheel in the form. But with the panel on it doesn't seem to fire the mousewheel event of the panel, or the usercontrol within the control or even on the form. The best solution would be to have an event fire in the usercontrol but I'd even accept an event on the form and feed it back into the usercontrol.

I have a WinForms application (OwnerForm) with some UserControl. When textbox of UserControl is changed, I want to filter content of a OwnerForm. But how can I make it? I don't want to specify OwnerForm inside the user control. I know a solution to add manually handlers for MyUserControl.tb.TextChanged to some functions on a owner form, but I think it's bad way. I'll prefer to have overridable functions, but I can't imagine how to do it.

I have a userControl (.NET 1.1 Winforms) that has a clickable picturebox as a button.Since I have lots of those usercontrols visible at the same time, I thought It could be nice if I just display the picture box when the mouse is over the usercontrol and hide it otherwise.To do so, I handle the MouseEnter and MouseLeave events of the UserControl, hiding and displaying the picturebox. That works fine.But when the clickable picturebox is visible I'm not longer able to click it (the hand cursor is gone and the click event is not firing).After some test, I realize that if comment all content on the MouseLeave handler that do something with my picturebox... this way the picturebox is clickable.I'm not using the correct event?
Here is the code...
Private Sub NodoEstablo_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.pictAdd.Visible = False
End Sub
[code]....
Update:If I resize the picturebox on MouseLeave (just to do something) it works.So far, changing Visible and Location in the MouseLeave prevent me for click the picturebox.
