Interface And Graphics :: Display The Rgb Code Of System Colors In VB2008?

Mar 10, 2009

Is there an easy way to display the rgb code of system colors in VB2008?

That is, I am looking for some code that will retrieve the names of the colors that are used in the system colors and display their rgb codes (and maybe show a sample), so I could display, for example, what the rgb code for "control" is.

Interface And Graphics :: Check For All Colors In An Image Without Sweeping Through All Pixels?

Apr 26, 2011

I'd like to check for all colors in an image. I've already came up with this:

Code:
Dim lst As New List(Of Color)
Dim img As Bitmap = System.Drawing.Bitmap.FromFile("C:image.jpg")
For x = 0 To img.Width - 1

[code]....

Unfortunately this needs to sweep through all the pixels, and it's EXTREMELY slow... method to get all colors in an image without sweeping through all pixels?

Interface And Graphics :: Menu Navigation For Large System?

May 26, 2010

We are in the final stages of releasing a new in-house written system within our company. We have opted to create a single system/project containing multiple programs (like a mini ERP system).We are stuck on the navigation mechanism which will allow the user to load the appropriate forms. I am personally not a fan of the Tree View control because I think it is unfriendly to users. I have been looking on the web for some inspiration and I am interested in the design of the OPEN BRAVO ERP system. Before we dive in though, I wanted to get other programmers opinions. What do you find works best in VB 2008?

Interface And Graphics :: Display Form As Part Of A Function?

I have only recently started using VB.NET after having a little experience in VB6. I am trying hard to force myself into this OOP mindset. I want to know if a certain thing is possible.

I want to be able to call a function in the beginning of my main form's startup sub. The function call would look something like this.

Code:
Private Sub frmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Interface And Graphics :: Display Long Lists Of Output?

Aug 15, 2008

I am trying to write a program in VB2008 Express. I originally wrote it in excel, but I want to add some features and make it a standalone executable. the program is ideal for a spreadsheet application though.

essentially, there are two input tables. each containing about 6 columns and maybe 10 rows. I assume that could be handled by arrays. the output would be a continuously updated table of output based on calculations using the data from the two input tables. the output table would be about 4 columns by up to 1000+ rows, and would need to be recalculated and displayed each time any data in the input tables has changed.

first, are arrays sufficient to handle this? would databases be more appropriate?

second, what's the best way to display a long list of output, that has a user defined length and is continually updated. it would also be nice to have the ability to click on an individual cell (or value) in the output and have more code executed.

is there a way to incorporate a spreadsheet like tool for this as a backend? I want to make sure i'm using the most efficient approach before i invest too much time.

Interface And Graphics :: VB ListBox Control Display Names?

Dec 20, 2010

I don't usually use VB but now I must for an assignment. I would like to know if it's possible to change the display name for an object on a listbox. For instance, if I add to it a user defined class, there's a way to provide it's display name, instead of converting it to string and then add it.

This is what I have

Dim format As String = FormatOutput(object)
Lista.Items.Add(format)

I would like to have the same output, but instead add the object.

Note: if such is not possible, then how can I associate the list box selection to the actual object? Doing it by index is painfull, because I'm using linked lists (ie., instead of arrays).

Note 2: python has a __str__ method which is called by default when the object is cast to string. Is there anything like it in VB?

Interface And Graphics :: Disabling Button Before Executing VB Code To Prevent Duplicate Records?

Aug 5, 2008

I need to disable a button after its pressed so the user does not have the ability to click it again as this would replicate the process in some cases. After alot of searching I found some tips - alot of code I found I could not understand.This is what I have come up with:

[code]...

I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:

[code]...

But although this works, it does not execute my VB code in the code behind page so I am a little confused where to go here.

Interface And Graphics :: Making A Custom Class That Mocks The System.Drawing.Rectangle Class?

I'm making a custom class that mocks the System.Drawing.Rectangle class because the Rectangle class doesn't have a name property. I need a name property because I am adding all of my rectangles to a collection and I need a little more info stored than just their locale and size. So I changed the _onPaint event but nothing is working out when I run the program?

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods.

Interface And Graphics :: How To Procede With An Interface Design Approach

May 18, 2012

I was wondering if I could elicit some tips on how to procede with an interface design approach.That is. What is a good way to go about establishing a "work area" where one can have multiple "floating forms" in this area.Can you have a form which occupies the entire windows desk top and the other forms "float" in this space? the "floating" forms would need to interact with each other where pressing buttons etc on them would affect other forms on the "workspace") Or what would be a good way to start accomplishing that? Or is there a better way to get the same effect?

Interface And Graphics :: Link A Class / Object To An Interface?

Apr 21, 2010

I'm trying to make a .dll that contains a lot of basic functionality that a program can use. Currently i am trying to use interfaces to make a lot of this functionallity independend of the program using it but i hit a snag. The Basic idea is that a programmer will create his own object using the interface discribed in my .DLL file. Then implements those functions as he likes. He can then instanciate a controller (found in the same DLL) and sends his custom object implementing the interface to that Controller. The controller can then be started and will take over all the work. I do not know what type of object is send to the controller and idealy i want to program it in such a fashion that i shouldn't care as long as the object send implements that interface.In code I am trying to achieve the following: (quite simplyfied)

.Dll:
Code:
Public Interface MyInterface '<----Decleration of the interfaceFunction GetData() As Integer
Function SetData(Data As Integer)
end interface

[code]....

this propperly. I know that the second i set the interface adaptor in the Controller VS comes nagging that it can not be converted to a "MyInterface" Class. Obviously i am doing something wrong. I can change the datatype that the controller expects to the "MyController" type but that would completely ruin the whole idea of flexibillity. I am hoping someone sees what i am trying to do and can point out where i made the thinking error.
