VS 2008 Pick A Color Option
Nov 12, 2009
I want to be able to use like a dropper to select a color that would display a html code output of the specified color picked. It would show the preview of the colors your scrolling through in the oval and a preview of what the color would look on text on a black background in the html section as html code. Unfortunantly I have no idea what the hell I'm doing, lol. I have been able to program simple programs that insert text in a text box pretty well including multiple colors of the text. But this is what I'm working with
Basically this is the whole form, theres obviously going to be a lot more which I'll try and figure out on my own. But this is basically whats going on with it. the color chooser button with have the dropper icon on it when I get the chance to add it.

I have made my program but I want to give users the option of choosing a custom color for text. I have an inputbox that works and then converts it to Color.whatever. But seeing as the user types in what they want and it is not done by the program itself it can throw exceptions.
Dim directresponse As String
Dim actualcolor As String
Dim isgood As Boolean
[code]....
That is my Sub, it will make Color.(userinput) but I need to check if Color.(userinput) is actually a color that VB.NET can understand and add set.
I have tried "System.Drawing.Color" I get told it is a type and cannot be used in this context.use System.ComponentModel.TypeDescriptor to convert it to a color and check if it is real and then set it.

Alright inside of a combo box I have a list of colors and I want to change the background color of the combo box to the selected color...basically this... but im not sure what the problem is here anyone have some advice or is this not possible?
CBLinerColor.BackColor() = CBLinerColor.Items.Item(0)
Basically i want dynamic code that will change the color depending on the items in the box.

I want the background of my form to be the same color as the window frame color that the user selects, even if that changes. I selected System->WindowFrame as my background color, but it always remains a dark grey, regardless of what I have my window color set to. How else would I achieve what I want? I assumed I was doing it the correct way. Do I actually need code that gets the system window color and then apply it?

I really like the coding speed that vb.net provides, but I don't like the possibility to forget to declare variable types, return types of functions, etc. and that is why in each class I use[code]..
Is there a way to define those two options on the project/solution level?

the combo box style 1 has both the drop down option but also a manual entry option. I need to know how to code it so that when you manually enter data, it takes that data and places it in a text message "The shipping charges for "data" is $15" displaying in a text box. Shouldn't be hard but have developed a mind block.

what does these two code means in vb.net: Option Explicit on Option strict on i think option explicit means the compiler is not going to do any kind of conversion and i need to do all of them by the code;also it becomes case sensitive i.e;

1. I have read that keeping Option strict on and Option infer off is good practice and will insure your code is tight and properly written. I would like input regarding this, pro's and con's from those who are in the know.
2. Having said that, I have set Option strict on and Option infer off in an existing program I wrote (that was working perfectly mind you) with them off and on respectively. I went through and cleaned up all the errors on the 'need AS' and casting of variables, but one is leaving me a bit put out.[code]
I have also read where using My.Computer.System.Directory.GetFiles() instead of System.IO.Directory.GetFiles() is probably not a good thing, but when I change to this I get no error, but also no dataI am thinking I should stay with the strict on and infer off but am really slogging through getting this code correct.Running Win7 on Dual Quad Core XEON Intel Extreme with 8Gb RAM.

I am writing a text editor program and I have written the new, open, save as, exit menu items but I am struggling with writing the save option.Now I have created the menu itself (well vb did, I just used insert standard items) but how do I code up the save menu option so that it updates the current document or if the documnt has not yet been saved bring up the save file dialog.Here is the code I have so far
Public Class Main
Private Sub NewToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewToolStripButton.Click, NewToolStripMenuItem.Click[code]....
I know I have some finishing touches such as messages and error handling and stuff but at the moment I want to get all the basics working,I think the save menu option is all I am struggling with at the moment.

Is it possible to create a standard installer with VS 2008 VB? What i'm looking for is an install similar to Windows Installer - one where the user can choose installation location, options, etc. instead of the ClickOnce deployment method of burying the app in the User folder in an unknown location?

In VB6 I would say "optReason.Value = true"
In VS2008 would I say "rbReason.Focus()"
And accomplish the same thing?

detect if the system has Hibernation enabled, or in the case of Win2k if hibernation is even possible. I already know how to hibernate the computer via the Framework:
Application.SetSuspendState(PowerState.Hibernate, True, True)
but in my program I would like to provide the hibernate option only if the OS A) is new enough to be able to and B) has it enabled in the user's Power Options in the control panel.

I am trying to set up an app that has a menu and have each option run on a different thread. When I set up 2 thread to run I get the following error: Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThread Attribute marked on it. This exception is only raised if a debugger is attached to the process.From what I have researched, it says to make sure the openfile dialog function should be used with the main thread only. Since I have <STAThread()> added above the main I'm not sure how else to handle this. The main thread needs to be listening for the menu options and if I change it around it runs that option and the other threads hang. [code]

What do you feel are best practices for the use of Option Infer in your projects? In Visual Studio 2008, Option Infer is a directive that allows the compiler to infer the datatype of a declared variable by looking at what is assigned to it. This is a key feature in VS2008 and is used extensively with LINQ statements and queries. However, turning on Option Infer may create pitfalls for future maintenance programmers.

Why is it so important to turn option strict on? I admit I am not a professional programmer, but I have written a great number of useful applications...I am fairly well (although self) educated in object oriented programming... I even write programs for my business...I always have felt that I am missing some background theory that is probably really important (I have a grad degree in math, no comp sci)...I have never turned on Option Strict for any project I have ever written, and I guess I just want to know, theoretically why is it important?
