Making ProgressBarRenderer.DrawHorizontalChunks Work Like Standard ProgressBar

Mar 28, 2012

Is there a way to make ProgressBarRenderer.DrawHorizontalChunks actually work the same as the standard ProgressBar rendering?

If you create a Class that Inherits ProgressBar and override the OnPaint event then you have to render the Empty ProgressBar and it's fill% manually. This pretty easy with the ProgressBarRenderer. However, the DrawHorizontalChunks function is ugly compared to how a standard ProgressBar renders itself.

Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
ProgressBarRenderer.DrawHorizontalBar(e.Graphics, e.ClipRectangle)
ProgressBarRenderer.DrawHorizontalChunks(e.Graphics, New Rectangle(0, 0,

[Code]....

I also have a second more minor issue in that I Shadowed the value property (for various reasons), so PerformStep (which then has to be Shadowed to keep the Value property in check) causes it to increase in blocks rather than smoothly growing between the two Values (old value growing to old value + step); the only solution I can see is to extend the code in the Shadows Sub PerformStep code to move the Value property gradually between the old and new values.

Add Standard Button To Toolstrip / Make Toolstripbutton As Standard?

May 27, 2009

I usually use standard button and do the settings like causevalidation etc if required.

i decided to use toolstrip and inserted some buttons but end up that it doesn't do the validation for control and also doesn't call leave event of textbox control.

so my question is, anyway to use regular button functionality for toolstripbutton or there is a way to add regular button on toolstrip.

Get The Standard BackColor Of A Standard TabPage?

Mar 11, 2009

I am trying to add a TabPage containing a UserControl to a TabControl at runtime, because the number of TabPages to add are determined at runtime.

The UserControl (objDataInfo) is just two Textboxes, two labels and two Radiobuttons, nothing too exciting...

The TextBoxes have their Anchor properties set to Left, Up, Right so they scale with the width of the usercontrol.

The TabPages are added in the constructor of the form, which takes the number of tabpages to create (n) as an argument:

vb.net
Dim cList As List(Of objDataInfo)
Public Sub New(ByVal n As Integer)

[Code]....

So... How can I get the standard BackColor of a standard TabPage?

(I tried leaving out the usercontrol all-together, but the TabPage still has a gray background...)

String Concatenation Won't Work Using Class?

Jun 14, 2012

I'm trying to concatenate two properties into one string like so:

public class thing
public property word() as string()
public property count() as integer()

[Code]....

This is what I want, but it doesn't help that its in the debug output...I need to put it into a single string. I've tried using a_thing.count(i).tostring, but it doesnt work. If I look at the arrays individually, they have exactly the contents I want. But I can't concatenate them. Does it have something to do with suppressing the new line that debug.writeline usually creates?

Getting BindingSource And DataGridView To Work In A Seperate Class?

Feb 19, 2010

Basically I try to get a DataGridView and a BindingSource working inside a class. I define them by:

Dim TempDGV3 As DataGridView = New DataGridView
Dim TestBinding As BindingSource = New BindingSource

When I manually add columns to the DataGridView, it works perfectly, but when I set it's DataSource to a bindingsource from a base class, it doesn't load data and keeps throwing 'object does not exist' errors. The bindingsource mentioned here did, however, work on other DataGridViews that are defined in the base class (and implemented in the form to which the base class belongs)

Same for the BindingSource(not the above mentioned, but the one I try to create inside the class in the beginning of this post). I try to use it in the following way:

TestBinding.DataSource = TempDGV3
TestBinding.Filter = filterString()
SourceDataGridView.DataSource = TestBinding

But the BindingSource keeps returning 'Nothing' for it's datasource and basically doesn't work. However, the SourceDataGridView mentioned here gets filled with 63 columns with "AllowUserToAddRows" and other properties when the columns names are asked.

So my question is: how do I get the BindingSource and the DataGridView to work in this class? I'm getting the feeling I'm missing out on something very obviously here. If that's not the case, I can report back with more code?

Class Property Access - Setup MyClass To Work Both Ways?

May 7, 2010

I can't seem to find the correct words to search for an answer. I'm using VS 2010 so I have auto-implemented properties.I have a class and I want to access the properties by a string.

Public Class MyClass
Property Prop1 As String
Property Prop2 As String[code].....

But, I also want to be able to access the variables something like this way....

Dim MyVar = New MyClass
MyVar.Items("Prop1") = "Prop1 Value"
MyVar.Items("Prop2") = "Prop2 Vaule"

How can I setup MyClass to work both ways?

Class Collection Property - Method - Allow For An Employee To Be Assigned More Than One Work Location

Jun 17, 2011

I am experimenting with a transition from my application built in VB6 to vb.net. I know, about time. At the same time, i am making changes and improving upon the original. One area that I am working on is within my employee class. very standard class, nothing fancy. One change I want to make though is allow for an employee to be assigned more than one work location. Employee has (is assigned) Stores. In reading about collections, it appears they are different in .net (as they should be), but I don't know what the sytax changes will be to implement my changes.

Asynchronus Output Capture (BeginOutputReadline) Method Doesn't Work From Separate Class In VB

Jun 11, 2012

I've got a simple tool written in VB in VS 2010 that has a series of command buttons which run Windows command files and the output is sent to a Rich textbox object on the main form (the comand files take awhile to run so I wanted the output to show up in the RTB as it was produced to show progress). All worked well until I made an update to the tool so that the series of buttons are no longer hard-coded, but created dynamically from information in the app.config file. To do this, I use a button

VS 2010 Datagridview - Bound To A Local Databse Table Through A Linq To SQL Class - Adding Does Not Work

Sep 5, 2010

I have a datagridview which is bound to a local databse table through a Linq to SQL class.

Everything works as I would expect, when the application runs, up to a point.

If, in the datagridview tasks pane I enable Adding, Editing and Deleting all work as expected.

If I disable Adding & Deleting, leaving Editing enabled, Editing works as expected.

If I disable Deleting & Editing, but leave Adding enabled, Adding does not work, despite the row for new records being displayed. I can move around the row but not enter data.

I suspect somehow its the datasource as opposed to the datagridview that is the cause of my problem but as I say, I can add rows if the Enable Editing option is selected.

Changing the relevant properties programatically makes no difference.

I've been searching for the reason for a couple of days without success.

I have a workaround, by leaving Enable Editing set and programatically setting each row during the RowPostPaint event to be readonly except the row for new records. I would just like to understand what is going on.

Why Doesn't The DeleteDirectory Method Of The Computer.FileSystem Class Work On "special" Folders

Aug 14, 2008

if they choose to use a networked version of my software, I will need the main server doing the authenticating. This is a problem, because from what I understand, it is quite easy to clone MAC addresses. I have looked into using the CPU ID and the HDD ID, but those are not unique, well at least I don't think so. Reason why I say they are not unique is because someone has the exact same CPU ID as me, and the HDD ID changes from partition to partition (same drive). Maybe the HDD ID is a partition ID instead? Anyways, I was thinking maybe I could get the Physical serial number of both the HDD and CPU, but I have not been able to find anything yet.

How To Develop A Standard C#

Oct 5, 2009

So, I don't want this to get into a flame war between C# and VB.NET developers. This is purely from a standpoint of a development department going forward. We've been a VB.NET company for years, but that was mainly due to who we've hired. That requirement has fallen off the wayside as of late, as we've pulled in 2 guys who specialize in C#. I used to be a C++/C# guy before converting to VB.NET for this company.

So, to everyone who has to deal with this whether on a hiring basis or a maintainability basis: how do you handle standardizing languages of choice going forward? I'm inclined to make a push for C#, as that'll make 3 solid C# developers here. But just curious what everyone's thoughts on this are.

PerformClick() Doesn't Work - How To Make It Work

Feb 2, 2011

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:

btnWhatever.PerformClick()

Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.
