Setting Form Bounding Location Property To Entry
Feb 25, 2011
VS 2008, vb.net, Win7 development machine. I've developed a Windows application with several different forms, and am using the My.Settings feature. This is the first time that I have used this feature. For each form, I have set the form's property binding 'location' property to an entry in 'settings' of My Project settings page of the VS 2008 development environment. The settings are set to user scope.
1.) Do I need to add any code to my application to make the settings work, or is it sufficient that I have the "Save My.Settings on shutdown" set to true?
2.) When I create my setup to install the application, what settings file (app.config?) do I install to the user's machine, and what folder should it be installed to?

I have a single form that I would like to move across the screen with my VB program. Of course it's simple to set the location X and Y property for compile time using the properties tab, but I want the form to move as the program runschanging the coordinates within a for-next loop.I can easily get the X and Y coordinates of the form within my program by using X = me.location where X has been dimmed as type point.console.writeline(X) will appear as {X=20, Y=40}. for example

I have a second form that loads when the main form loads. It sits behind the main form, is mainly transparent and does not allow interaction from the User.
Its as if the form is on the desktop, which is what I'm going for.
I set the location of the form to be in the top right hand corner of the desktop. On my PC, which is a 23" monitor, it works and looks great. But when I use my application on a notebook or a smaller screen, the form gets cut off. Why is obvious, because of the screen size differences.
What I want to know is how I might set the form to a more... definitive position. Rather, relative to the size of the screen.
I haven't searched much yet, but maybe there is a way to set the location of the form to a specific location of the desktop, not relative to the size of the screen.

I'm having trouble setting a form's location in the load event.
config_set = File.ReadDatabaseKey(Public_Variables.settings_radar, _
"Window Position X", Public_Variables.config, Public_Variables.config_path, 5)
If Misc.GetContainsOnlyNumbers(config_set) Then
Me.Location.X = CInt(config_set)
End If

I'm working on a vb 2010 project where I am playing mpeg movies using the Media Player control.The computer has dual heads (extending windows desktop to other display). My aim is to be able to selectwhich screen to show the video on. I have two forms, the first form (frmControl) has two buttons, Play and Stop.The second form (Player) has the embedded Media Player. Initial tests worked fine (not choosing a screen, but making the player fullscreen and playing a movie). When I add the following code to allow choosing the screen

How would I make my form unmovable so you cannot drag it to move it? I also need to know how to make it always start in the same exact spot. I don't know why but it changes spots even thought the location is set: 0,0

Im pretty use to doing loops (although still relative new to vb) in my code however am having difficulty setting up one that picks up an entry in one data table and then sums a field in another where records have matching criteria. Example:
[Code]...
What i am trying to do is set up a datagridview on a form that shows the summary data. The time is controlled on the form by a trackbar (output to textbox) and I started setting up a loop using (For/Next) to isolate firstly the matching entries in field 3 (time). This works fine. I then used compute to sum the the field 2. However what i want to do is to loop through table 2 and where entries match i.e. where Field 1 in table 2="A" sum matching entries in table 1 where the DateTime matches.

In on a section of my book about classes and properties. In this example, the author is attempting to show how you can validate a value passed to the property before setting the property. Looks like so far in this book, a couple of things have slipped past the editor, and I think this might be another one...Here's the example:

I'm working on the Inventory section of the project I'm working on. This particular form holds a tab control, by default it has 2 tabs one named General, and the other named "New..". When the user clicks the New tab an input box opens to collect the name for the new Department, it then changes the name of the current "New.." tab, and then adds another tab and names it "New..". This process continues until they reach their limit of departments. The problem is that when the tab gets renamed, a listview control needs to be added into the tab. Adding the new control is simple, but setting it's position as the one in the previous tab has seemed to elude me. This is what I've tried.
Private Sub TabControl1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TabControl1.Click
Dim SD As TabPage
SD = TabControl1.SelectedTab

I have a simple exe that loads a page from my site in a webbrowser where users need to enter login details to get on a secure page. Now everything works ok, except I have to use php for this and yeah cookies. So, I want to know if it's possible to set a special location for the cookies, since as some members report, they clean the cookies daily and this makes my exe "forget" that they are logged in. Any way to store cookies on same location with the exe so it won't get deleted by 3rd party tools like ccleaner or so.

We're exporting a set of data using .net interop to Excel and our template file contains some images. Depending on the amount of columns we're exporting we want to position the image X pixels left of the last column depending on the image size/width. Using the record a macro function moving the Image around is a 'no op'. Setting the Shape.Left position also won't work.

Just started using the Windows Browser in one of my forms so the user can select a photo they need to load. This was surprisingly easy (This seems to be the norm in Basic, if you think it will be hard it isn't and visa versa). What I am struggling with is how to set the default location to 'Computer' rather than a disk letter and directory name. The photo is most likely to be on a card reader or Memory stick so the drive letter is likely to change.
I am guessing the command will be:
OpenFileDialog1.InitialDirectory = ???????

I have the following property in a class:
[Code]....
The problem is that when I try to set the property like this: myClass.Language = "English" The property is set to "English" and not to "<![CDATA[English]]>" which is what I want. What is the reason for that and how can I fix it? When placing a break point on End Set and use the Watch window to inspect the value of _Language after setting the property to "English" it remains "English" and doesn't change.

I would like to know if its possible to bind the property LOCATION of an object like button.[code]So that, every time I move either the hscrollbar1 or vscrollbar1 the button1.location will change or moves the object to the location of hscrollbar1.value and vscrollbar1.value. It should happen without setting its value using the SCROLL EVENT.

This one has me stumped. I'm trying to change the location of an object's X position so that it has a marquee like effect. I'm doing this with buttons and text, etc..
PictureBox1.Location = New Point(PictureBox.Location.X - 10, PictureBox.Location.Y)With the intention of it moving 10px to the left. I would then use a timer, but it scrolls automatically for me,

I am converting a 1.1 .NET web app to 3.5, and I've run into a bit of a jam.
One web control has a Property that sets the page title label on that web control.
End Property
When a page with the web control was loaded before, it would set the Property to a given string, like in ucHeader.PageTitle = "This is a string." Now, if I don't remove the lblPageTitle.Text = Value, I get a NullReference Exception.

I'm new to classes. In my Who wants to be a Millionaire application, I have a Lifeline class and I create three instances of it - FF, PAF and ATA (50/50, Phone a Friend and Ask the Audience). Something I do with a lifeline is put a cross over its logo, hence the need for a centrepoint property, which marks the centre of the cross on a form.
Public Class Lifeline
Private ptCentrePoint As Point
Public Property CentrePoint() As Point
Get
CentrePoint = ptCentrePoint
[Code] .....
What happens is that at the "Call Form2.DrawCross(Form2.CentrePoint)" line, the tooltip shows that the FF object's centrepoint property isn't set (as I thought it would be by " FF.CentrePoint = tmpPoint").

I am having trouble getting the Student Name entered in the Student Name Form to change the Text titles of the GroupBox's on the Main Form and Schedule Form. I understand the logic of what needs to be done to some extent, but I am having trouble coming up with the correct coding.
Below is a snippet of the Student Name Form code that I tried most recently just to see if I could get any change to happen to the other 2 Forms when the Accept Name button was clicked. As of yet, I cannot get a change to happen at all in the groupboxes of the other Forms.[code...]

I have this simple code,
Protected Sub grdSearch_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdSearch.SelectedIndexChanged
TimeOff.Where = "UserName=""" & grdSearch.SelectedValue & """"
End Sub
Doing so causes this error, 'UserName' could not be resolved in the current scope or context. Make sure that all referenced variables are in scope, that required schemas are loaded, and that namespaces are referenced correctly. Near simple identifier, line 6, column 1.
The datasource works fine before the where property is set.Update: I found the issue but I still don't get it.Adding it. in the where clause solves the issue. Like this,
TimeOff.Where = "it.UserName=""" & grdSearch.SelectedValue & """"

I am using a user control using vb.net. It include the program to retrieve the values from database while giving the paramers. When I set the property from my main program i am getting an error "Invalid attempt to call Read when reader is closed." When i gone to the online help i got the message as follows "System.InvalidOperationException (.NET Framework 4)The exception that is thrown when a method call is invalid for the object's current state. InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments. For example, InvalidOperationException is thrown by IEnumerator.MoveNext if objects of a collection are modified after the enumerator is created, or ResourceSet.GetString if the resource set is closed before the method call is made. If the method invocation failure is due to invalid arguments, then ArgumentException or one of its derived classes, ArgumentNullException or ArgumentOutOfRangeException, should be thrown instead.[code]
