Constant Window Flashing?
Jun 16, 2011
Alright, So i have two forms open. One in a listview and i have another window with a browser control in it. The browser is adding data to the listview but i made it so it hides while doing this using Me.Hide(). I can make it appear if i click the menu item "Show browser" i made.when im on Form1 (the listview) and its doing its thing with the browser window hidden. It keeps making form1 flash. Well not flash but like the browser window is poping to the front (while hidden) causing me not to be able to click on anything on Form1.This happen everytime the web browser navigates somewhere.Making Form1 always on top fixes it, but it also gets on top of other programs like my web browser . I want it to be on top only to the web browser.

When building a class library which contains many classes, all classes uses a lot of common constants and functions, what is the best to do:
1- Declare these constants and functions as public in a module.
2- In each class declare constants and functions used by individual class as private.
The first choice is good for easy and fast implementation, but re-using a class in a different project will require importing the module to the other project.The second choice require a lot of copy/paste for code snippet but a class can be re-used in different project easily.

Problem: I have a listview control that gets populated with devices that are offline and after so many failed attempts, it will begin to flash, alerting the user.The code I use currently works, but seems almost random. The first time an item is added, it flashes just fine. Once a second device gets added, both items will stop blinking. A third item being added causes only the 3rd item to blink (first 2 still not blinking).
Here is the code I am using.Question 1: Why is this behavior like this?Question 2: is there a better way to have a list item "flash"?*After so many failed attempts, it triggers a timer to start, and in the tick event is this code*

I have a datagrid with planned orders for loading (like the flight schedules at airports). If the status is "ready for loading" I would like that value to flash based on a timer. I managed to do it with text on a button, but because this is a datagrid it is more difficult for me and I am a bit confused.
Here is what I have for code;
Private Sub OrderOverviewDataGrid_CellFormatting(ByVal sender As Object, ByVal e As DataGridViewCellFormattingEventArgs) Handles OrderOverviewDataGrid.CellFormatting
If Me.OrderOverviewDataGrid.Columns(e.ColumnIndex).Name = "Status" Then
[code]....
Everything works fine. The column "Dock1" has the right color and the statuses have the right colors to, but; I want the "Ready for loading" status to blink based on Timer_2 which I have put on the same form.

First attempt at using the error provider, I've set this up for each of the five text boxes I have on my form, when I click the button it shows the error provider flashing between the various boxes if I leave them all empty. Ideally I'd like the form to show the symbol next to the box thats empty, click the button and remove it from those which are correct leaving only the incorrect text boxes with the symbols. Any thoughts? [Code]

I have a button on a form that when clicked i want to have it flash a few times. I have tried creating a for-next loop using the visible true/false property but I only get one result, that being false.
I also want to vary the lenght of time between the flashing.

I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
Dim picLight(2) As
Boolean
For intX

I made a working program to calculate piza slices, i was told i needed to declare pi and the areas as constants. when i rewrote the program it no longer works. the result keeps coming back as 0.

I have strMyColor = "Red".I would like to make lblMyLabel.BackColor to be red.Without using a variable the code would be this:
lblMyLabel.BackColor=Color.Red
I tried using the variable like this: lblMyLabel.backcolor="Color." & strMyColor
But the error is that a string can't be converted to System.Draw.Color. I understand that, as the string "Color.Red" is not the same as the VB constant Color.Red.Is there a way I can construct a valid vbConstant from a string?

I mean why? I mean to organize things I often turn modules into classes where all the methods are share.But then I thought, why not organize them into namespace?But then we can't declare constant in namespace.

I need some of my initialization code to be blocked off if I am in Design Mode. This code is ran in the new method of the form, so it runs before the DesignTime Property can be set. Is there, or is there a way to setup, a compiler constant which indicates whether or not you are in Design Time. The Debug Constant doesn't work because when I run the application in Debug mode I want it to run
