View 7 RepliesI'm not sure if this is a bad way of building an application but let's say I have 30 WPF Windows for different screens in my application. I want to build them into a DLL so I was wondering if it is bad design to instead of creating each window as a window, if i can have 1 window that hosts whichever screen is open. So the windows will actually be a usercontrol, or at least act like one. So when you want to go to a different screen, you would just change the content of the 1 window to the content of the "usercontrol" that you want displayed.
View 3 RepliesI am trying to troubleshoot a VB.NET project that contains UserControls (actually, several of them that are displaying the same issues). I am trying to get them to build under x64, but it is impossible. In x86 or AnyCPU, the UserControl builds and shows up in the Toolbox, so I can add or modify it in the forms that require it. In x64, the controls disappear from the Toolbox, I get warnings during build (the current project builds though), I can't see any of the forms - I get errors (please see below) - and projects that require the project with the form as an import will not build.
When I was studying what these UserControls are so that I can maybe rebuild them from scratch, I downloaded code from a book - great learning tool, but I get the same errors[code]...
I'm using Visual Basic in Visual Studio 10 Beta 2.
I did make a library with UserControls In VS2010 and I did a build. After that I want to use my UserControls from the library in a new project in VS2010.
How do I get the UserControls in the ToolBox when I'm desiging? I tried some import statements, but without result.

I also set a reference to the dll file of the library, but still I don't the UserControl in the TooBox.
I am working on a project and there are about 30 controls that I need to call and update at runtime. I have named the controls day0 - day35 (it is a calendar). Basically, at runtime, I need to call each control's setDate function to display the day number. When I run it, the array just has null/empty.This is the array I am trying to use in the code behind. The controls are names day0-day35.
Private dateArr() As ucMonthDay = {day0, day1, day2, day3, day4, day5, _
day6, day7, day8, day9, _
day10, day11, day12, day13, day14, day15, day16, day17, day18, day19, _[code]....
When this gets called, I get a null pointer exception.I do not understand why the controls are not in the array?
I created an item user_control that has a textbox, button, etc. which will intentionally collect the total quantity of items the user wants.
I dynamically create a few intances of user_control on page_load. If you click the add button for the item quantity it will add to a session variable. however when the user enters a different quantity in the textbox and clicks the add button the total is of the original value of the textbox.
How to get the value the the user has typed in to the textbox to add to total???

View 3 Repliesi've been trying to use customcontrols made in vb.net 2008 but when i try to add them to a vba form using
Dim x as new MyCustomControl.Usercontrol
Me.Controls.Add(x)
it returns "activex can't create object" The control itself has nothing special, it's just random textboxes and a few buttons. why i can't use the control?

I am having difficulties initiating the 2 usercontrol. The first one works perfect but am not quite sure how to get the second one to initiate.
Code for Custom Tabpage Class
Public Class TabPageEx
Inherits System.Windows.Forms.TabPage
Private WithEvents uc As New UserControl1
[Code].....
Now, I am struggle on how to inititiate the second usercontrol still using the TabPageEx Class. Do I need to make another seperate Class Such as TabpageEx2 too handle usercontrol2? The usercontrol2 needs to happen on form load so that the tab is always present.
Where can I get more information on how to work with usercontrols in vs2010 (VB.NET) I have been programming using mainly form level applications. I have a project I want to convert from windows forms to usercontrols.

View 15 Replies[Using VB.NET 2010 / targeting the .NET 2.0 framework]I'm getting some unexpected behavior with panel scrollbars, and was wondering if it is a bug, or simply something that I'm failing to do correctly.Basically, I have a panel with Autoscroll enabled. Then I put some other items inside the panel, and then make the panel smaller, so that the panel's scrollbars appear.
Outside of the panel I have 2 buttons -- named "scrollOn" and "scrollOff", which turn the panel's scrollbar's on and off using the "Autoscroll" property (for example the "scrollOff" code I'm using is Panel1.AutoScroll = False ).
So after I run the program, I move the panel's scrollbar down a little bit with the mouse (this part is necessary to reproduce the bug). I then click the "scrollOff" button (which should make the scrollbars disappear). But when I do that, the scrollbars are not only still visible, but they "freeze up" (can't move them with the mouse anymore).
I'm having a bit of trouble with creating one of my custom controls. What I've got is a listbox within a usercontrol, and I need to be able to click on the lists items while still in the designer. This would make it act much like the tabcontrol.

Here is my Code snippet

Dim tabcount As Integer[code].....
The trouble I'm having is working out a way to be able to call the objects in the dynamically created usercontrols. I thought a list maybe an option but I am struggling to get the syntax/get it working. Wondering if anyone has some ideas or different approaches..
I have an application which has a tabcontrol that contains two tabpages. I have a custom made usercontrol docked to fill up each of those tabs. When I resize my main form to the minimum size allowed one tab resizes accordingly while the other seems to overflow the area and a couple ui items slip out of access/view.
One usercontrol was quite literally copied from the other and renamed and fields adjusted. The usercontrol size is the same between the two. Within the usercontrols there is a datagridview and a large panel full of textboxes and they have identical sizes and identical anchoring properties and even the same location coordinates.
I'm struggling to find a difference between the two but I really would like the resize behavior to match between the two usercontrols. I was wondering if anyone would have ideas of other things to check I did not mention here?

View 1 RepliesI have 2 richtextboxes on a form and I want to link their vertical scrollbars i.e. ifrichtextbox1's scroll bar is moved then richtextbox2's scroll bar moves by the same amount.The reason for this is that both richtextboxes will contain almost identical text barring a few differences in the second richtextbox. By linking the scroll bars my hope is that the user can better compare the textboxes for any differences between them. I have looked at trying to find a scroll bar property but can not find one. Does one exist?

I searched the forum for this and couldn't find anything. Maybe someone can help me on this.I have a child form that has a ToolStripConatiner that holds a ToolStrip, StatusStrip and a PictureBox. I need to have scrollbars when the picturebox is larger than the form. I set autoscrollbars to true on the form but after I added the toolstripcontainer, the scrollbars no longer appear.
The toolstripcontainer is not docked but is anchored to the top,left,bottom and right. I tried unanchoring from the right and bottom, but still no scrollbars.
Does anyone know of a way to make the scrollbars appear, or maybe I am doing this all wrong and can give me a clue.It all works like I want it to except the scrollbars do not appear anymore.
