VS 2008 Wrong Icon Displayed
Feb 13, 2010
I had a default Icon I set for my windows form app in the properties section of the form. Since then I have changed to Icon. However, on the Task Bar at the bottom of the screen, if there is more than one form opened and Windows groups them together it displays the old icon image next to the group name. How do I change this to display the new icon image?If I go into the Application settings in the properties of my windows form, it has Icon: of the new icon file. I have changed it here and on the forms themselves. Still, the old icon shows up!

I have an issue with the icon displayed on the desktop. I have used the project's properties, application form and used the dropdown menu under icon to associate an Icon to the application. I have done this loads of times before and it has always worked.

I have attempted this code for an application that calculates and displays change in terms of quarters, dimes, nickels and pennies. The user inserts the amount paid and the cost of the item both expressed in cents in two textboxes. Then I have four labels displaying the results for each kind of coin. This is the process for the button I named Calculate:
Private Sub btnCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalc.Click

I was testing article [URL] to see if I could use this to populate a listview2 with the icons from Directory.GetFiles(apath) and getDirectories. If you go into c:windowssystem32 the program will hang for about 4 mins then if you go back to windows then back to system32 you will get the error.
win32 handle that was passed to icon is not valid or is the wrong type.

I found some great code on capturing webcam images but the problem is the client PC will need to initiate the communication to this server (click Connect to server IP). This is like 2 way communication.How can i do something like this (door Kiosk system):when a visitor press a button on the LCD that come along a web cam (this will be the server), it will send the signal the client PC that is installed with the application i've created (window form) and pop up the images to the client PC (more like a 1 way communication). This image is captured through the web cam on the server to capture the visotor's image waiting outside of the door. How to do this?I'm really stuck as i'm not familiar with window API programming yet.
1) how to do the mentioned 1 way communication? possible in .NET?
2) how to make my application to be at the tray icon just next to the time displayed on the right bottom corner of the task bar? When a visitor press a button o the server, it will pop up a window form on the client PC showing the image captured via the server's webcam outside of the door.

I'm not sure exactly if the folder icon is in shell32.dll, but nonetheless if it is.Basically, whenever I come across a folder in a FileSystem list, I want to add the icon for a folder to the image list that I am using for the ListView. The problem is that I'm not sure how to reference a specific icon location in a icon collection in a dll.Is this possible with Icon.ExtractAssociatedIcon and shell32.dll?

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

I've built my first usercontrol for use in a GPS Mapping forms app.
pic1 shows "panel1" containing some picturebox "tools" with a map(another panel containing a picturebox) underneath.
Pic2 shows that I dragged the map and the "tool" have not moved with the drag.
"panel1" also contains my usercontrol( this will show a transparent map scale). My usercontrol and all the "tools" definately have the same parent - ie "panel1".
If I resize the form to cause a re-paint of all the controls I get Pic3 - the red T bar (my usercontrol) will be the map scale.
Everything looks OK until I drag the map - the user control goes with the drag. Pic4 shows that the usercontrol image has been erased as it passed under the "tools".
I don't understand why the "tools" stay put and on top of the map and the usercontrol does not - even though they all have the same parent.

nserting values from a datagridview into an access db. However the values are wrong. As you can see in the code, I've made variables to check what values are fetched from the datagridview, and those values are correct. But in the db there are other values. What's going on?The thing is some of the fields are run-time-created comboboxes and there are also datagridviewcheckboxes. But like I said, the values in the t1...t7 variables are correct.

I'm using my.settings to save the load time of the solution. When my.settings.load_time value is changed and use my.settings.load_time.save() to save them. When I quit the application and manually start it again, the newly saved settings are used.
When I use either application.restart. The application will use the old values for my.settings.
My question is.. Is there a way to restart the application using either application.restart which will use the newly saved my.settings values?

My application was built with VB.NET application. It's EXE application. It's already running well on dozens of Windows host (as independent app - without development env). Now I try to run it on Windows 2008 server (as independent app), but the form does not displayed. Nothing is displayed. When I debug, I see that it's running all "form_load" subroutine, but then nothing is displayed. It works fine on many other Windows machine. What can be the reason? What should I check?

i seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:

How come when I design a form it isn't displayed properly on certain computers in the fact that buttons near the bottom go of the bottom of the window. I beleive this only happens with Windows XP however it might be due to screen resolution, I haven't troubleshooted it much.

I am working on a game launcher, and I need to display a "Splash screen" until the main game has started. For this, I need to know whether or not the Process has a Main window that is fully loaded and displayed.Now I noticed the main window handle is 0 when there is none, so I tried to use that:[code]But the handle never becomes nonzero. I tried to use the title but to no avail.I do not want to go into "Thread.wait()" since then the splash would remain even if the game is already launched.

I've got the collection and the items that the collection holds working ok, and I've got a handle on how I'm going to display the information on the face of the UserControl. However, my problem is how to fire the Method that displays the thumbnail on the face of the UserControl when a new Item is added to the Collection?

I dipped my toe in the world of user controls as needed to double buffer a panel control and now want to create a picturebox control with a thicker border. Writing a dice based game, the dice represented by pictureboxes when clicked are highlighted and their border style changes FROM BorderStyle.none TO BorderStyle.FixedSingle, which is where I want to increase the thickness of the border. My user control code increases the border thickness using the code below:-

I'm trying to do this division and the result to be displayed on a eight decimal number.
Dim r1 As Integer
Dim r2 As Double
r1 = Val(TextBox16.Text)
r2 = r1 / 60
TextBox18.Text = FormatNumber(r2, 8)
The value or R1 on this case is 273.4 but it varies according with the result obtained so I can not allocate a constant number to r1. The problem is the result that I am getting is 4,55000000 instead of 4.5566666

I currently have the following code but I would like to get away from going to a physical location. If I have the icon as a resource, how can I programatically add the icon? I don't want to use the form's designer to do this.
Sub Form1_Load()
Dim ico As New System.Drawing.Icon("C:Resourcesicon.ico")
Me.Icon = ico
End Sub
