VS 2008 - Using VScroll Control On Form
Mar 25, 2010
I am trying to use a VScroll control on my form but it seems it doesn't want to cooperate! Here's what's going on : I want to use a VScroll control with these simple properties :
Minimum = 5
Maximum = 10
SmallChange = 1
As we all know the VScroll has an arrow facing upwards and another facing downwards. I simply want to press that cute little arrow that looks upwards and to increase the value by 1. Respectively, when I press the other cute little arrow facing downwards I would like it to reduce the value by 1. However that uncooperative controls does exactly the opposite thing! I looked in MSDN and in a VB2008 book I have and found out that actually the up arrow is used to decrease the value! In the whole universe upwards means increasing and downwards decreasing, how come VScroll is not respecting that?

My problem is that the RichTextBox control has VScroll and HScroll events, but the TextBox control doesn't have such kind of events. It is possible to follow continuously the first visible line of the textbox by means of the SendMessage Api function in a thread and in case of the change of the first visible line, we can say that the VScroll event occurred.
[Code]...
This code runs correctly. However my program is extremely slowing down with this method. How can i solve this slowness problem or is there more practical way to learn when the textbox is vertically scrolled?

The following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

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 have added a freshly compiled ObjectListView.DLL to my VB.NET project and I've added a ObjectListView control to my form. But, thus far I have been unable to do anything with it except make it throw exception errors of various kinds. I know I'm not supposed to use it using the same syntax that ListView uses, but the documentation for this control is as well developed as MSDN's for ListView--which is to say vague to nonexistent. I can't use ListView because it gives me no control over row height and cell padding. Both need to be minimal, but with the defaults used by ListView, you could move in and and make a living between the entries. Too much space. I need things compact because the application I'm developing needs all the real estate it can get for other purposes.

I need a function that returns a control within a form based on a string name. I've tried Jim's method here, but then found out that it will not work with SplitContainers. Therefore, I feel like I need to use a recursive function, or maybe a stack. I've tried many different examples online, but I can't seem to get any to work.
This is the code for the latest try, as taken from here:
Public Function FindControlRecursively(ByVal ParentControl As Control, ByVal ControlTobeSearched As String) As Control
Dim FoundControl As New Control
For Each CurrentControl As Control In ParentControl.Controls
[Code] .....
Note that the above code only seems to return a blank control.

I have been trying for ages to put an ActiveX control on a windows form for a CCTV camera I am using. I have registered the control with windows, added it as a reference to my VS2008 project and now it appears in the toolbox.When I put the ActiveX control on the form I always get an error saying "Failed to create back buffer surface" The control is added to the form however I can not get it to work and I suspect it has something to do with this error.I have an example project from the developers of the camera that does not have this problem, i.e. I can add the ActiveX control with no problems, however the program is in C++ and I am using VB.Net.Is there anything else I need to do to stop this error from occurring?I am using a CCTV camera from Zavio (F521E). The ActiveX control is called AxVideoView.ocx.

I have a Mdi form and I need to put a control on the form which the user can resize. Now I need a container can be dragged by user to increase it's size. The split container will not work in my case as I have childforms and stuff. I want a container whose size can be increased by dragging it on one side.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Graphic As System.Drawing.Graphics

just wondering if it is possible to have a form and then load up a control on that form but so it runs in a different thread to its parent... i tried:
[Code]...
But it still seemed to be running on the form's thread And just so you know ctlMTTest is just a control that has a button on it, that, when you click the button, a loop runs.

I have a form which has a user control in it added dynamically. How can I change the values in that dynamically generated user control? All my functions are in a module and I will just call them in main form. So in module how can I find that user control and change its values? I tried writing a function in user control form. Like it has 10 txt box and I tried to pass a structure as argument in that user control form but I am unable to do so. when I tried to declare the structure outside function parameter in user control form it works well but not as function parameter..

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.

I have my forms all set up, I want a button on my main form that says Volume. When clicked it either opens a window above the current form with a volume control. Or opens another form that has the volume control in the center. When the slider is moved up to 100% windows is at 100% volume, when moved down windows volume moves down also.

What I'd like to do is in my application move a control like a groupbox or frame with content on it from e.g the main form to a tabpage on that same main form using code.
I can change the position of the control using it's location, but I haven't got a clue on how to move it from the main form to a tabpage, or from 1 tabpage to another.
-Is this at all possible and if so, how can it be achieved?

I have created a custom Combobox and added it to my toolbox, and it works well. Now I have added a custom ListBox to the same file as the combo box, but it does not show on my designer when I place it. I can however add it at runtime.
''ComboBox
<DefaultEvent("SelectedIndexChanged"), _
ToolboxBitmap(GetType(System.Windows.Forms.ComboBox))> _
Public Class ProjectsComboBox
Inherits ComboBox
''My Customization

I have tried removing the "DefaultEvent..." and still no dice.

I've got a richtextbox control on a form and a menustripitem that allows me to change the font style. What I want to be able to do is to allow the user to type text into the richtextbox control; then if they change the font style using the menu only for newly entered text to change font, and any previously typed text to stay in the previously selected font. The problem I'm getting is that all of the entered text's font style is changed.

I need to be able to change my form's opacity without changing the opacity of the components.
I really only need to do this on one form in my entire app, so this is getting a little frustrating
I've been researching for about half an hour now, trying to figure out if it's possible, but I'm coming up short.
I've seen some WPF examples and if it really comes to that, I'm more than willing to change the app from a WinForms app to a WPF app. I've made a WPF app before, so I'm familiar with it. But, I don't want to have to remake my entire project for this one form.
On that note, does anyone know if I can make a WPF form how I need it and just import it into a WinForm app? It doesn't seem possible, but it's better to ask than not. I'll look into this more.

I'm constructing a Management system. Now, I have a problem with the interface design.
I wish to use ForumsAccount's tab control and JuggaloBrotha's gradient form in my application (both can be found in CodeBank).
But the problem is, I'm confused in the design ! Which one shall I use for the main form ? an MDI form or a normal form ?
Details about the Mgmt. System app: it will be used to manipulate everything for a small firm, like adding customers, employees, payments, etc.. Everything is managed using the app and saved to the db.
