I created a typed dataset a day or so ago, then I added a whole bunch of tableadapter/tables with some relationships etc... suddenly out of nowhere it decides my dataset "is not defined". everywhere in my code where i use this dataset now has an error. I tried not to pull out my hair and do a Clean then Rebuild solution... out of nowhere it just refuses to generate code. Object reference not set to an instance of an Object. It would be nice if it was my object so i could find it but it's not.
Curiously I also lost the little database icon on the dataset in the solution explorer.I can still open it in the designer and preview my queries etc... it just wont make the code. it's driving me insane. anyone got a solution?
I've uploaded in SkyDrive my project to give a better picture of my problem:Cascading Combobox works just once in _SelectionChangeCommitted, and, DataGridView do not follow 3rd Combobox filter?
I am making a program that requires a user to login, then monitors the actions and time spent on the computer. However, it is being bypassed with the WindowsKey or Ctl + Alt + Del. I need a way to either remap those keys or somehow diable them. I tried the standard remap with regedit but that requires a restart and I want them to be able to still use the keys later.
I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

If we have a htmlanchor element. Is there an elegant way to know whether the link is no follow or do follow after taking into account that tag and context of the links.
Earlier I was working on a project, and I added a StatusToolStrip and the the ToolStrip I added a label and a progress bar. The label will say the current sub or function that is in progress and the progress bar will show how far along it is through the sub or function. I have tried this myself but I cannot figure it out as I rarely use progress bars.
An example of a code that I would like the progress bar to show would be like this: Private Sub StopServer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StopServer.Click 'Checks to give server notice If My.Settings.warningmessages = True Then Dim cmd As String = My.Settings.warningmessagetext(2) [Code] .....
So while the sub is running the label would say "Stopping Server" and the progress bar would show how far along the sub is.
I have a short little program that has an image follow my mouse cursor. But the problem is that the image keeps drawing itself over and over. I only want 1 image following my mouse.
Public Class Form1 Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove Dim myBitmap As System.Drawing.Bitmap Dim myGraphics As Graphics [Code] .....
i want to make a custom mouse cursor but I found that can be hard so I want to go the next best route. I want to see how you make an image follow the mouse pointer. I assume it would use some kind of image = mousepinter new point (x, y) or somethign like that. Suggestions or samples? In the end i want to take this code snippet and make a duck hunt game and a whack a mole type game
I'm making a minigame where the user moves their mouse around a picture and a little image of a stick figure follows that image. I've got part of it to move, but it only moves up and down.

In VB.Net with Winforms how do I make an image follow the cursor even when it leaves the form? I want to do this during a drag and drop operation. BCL and/or GDI is better for my usecase than P/Invokes.
If you are familiar with PeaZip, it does something of this sort when dragging a file from it's interface.
How Can I make a PictureBox follow my mouse when a MouseDown happens? When I click the left button of the mouse on the picture I want it to move with the mouse until the MouseUp.
Dim _Brush_Disabled As New SolidBrush(Color.FromKnownColor(KnownColor.GrayText)) Dim _Brush_Enabled As New SolidBrush(Color.FromKnownColor(KnownColor.WindowText)) Sub Do_Something()
[code]....
Will _Brush_Disabled and _Brush_Enabled automatically change their colors if the Windows color scheme changes?If not, how can I make them 'track' Windows color scheme changes?
is ther any way to make my screen follow my sprite? I want the visable area of my game to change when my sprite moves past this X value 284 but i can not figure it out ill post my VB Express code below
I have the following statement: ReDim lsDataMergeStart(lsDataMergeRange.Length)When I follow the execution in the immediate window, I get the following results: lsDataMergeRangeLength =1 lsDataMergeStart = 2 Why?
In a game i am making, as the mouse cursor i have crosshairs (like those in FPS games) and i would like an image box to change images as the mouse moves so that it appears that the character in the picturebox is following the mouse cursor.
i thought i would do something along the lines of first finding out which side of the picture box its on (left or right) then finding out exactly where with some maths equations and then assigning 1 of 60 pictures so that it appears that the picture is rotating.
I�m trying to implement a licensing schema for a template that uses the follow code snippet. (using VS2010 vb.net4)
<LicenseProviderAttribute(GetType(RegistryLicenseProviderSave)), _ GuidAttribute("2de915e1-df71-3443-9f4d-32259c92ced2")> _ Public Class Form1main ��. Form code etc. End Class
I need to utilize the GUID value in other classes within my application, as an example, as making registry entries.My goal is to have this editable at only 1 place in the template.I�ve created a Friend class that has the GUID string in it, but I�m unable to get the above to recognize the string. I�m sure that the code is simple, but it evades me.I would really like to do is to access the Guid that VS2010 vb.net creates (Project->Application->Assembly) shows and insert it into my application.
I'm working with a project that is WPF and VB.net. I want to visually simulate "dragging" an object (though I do not want to use standard drag and drop for reason of purpose).Basically, I have a label object that, on its MouseDown event, I want it to follow the mouse cursor inside a 640x480 solid-size grid (but not outside of it!). Mind you, this grid is centered inside a full-screen window. Again, the object should not follow the mouse outside of the grid (I'm guessing a "ClipToBounds = True" here)Then, on the label's MouseUp event, I want it to either stay in its current position or return to its original position, as determined by the value of a boolean variable set by another object's MouseEnter property.Note, if it would be easier to work with, I can change the grid to a canvas in a cinch. I'm guessing that would be desirable.
How do I make the object (label) follow the mouse cursor inside the grid/canvas, but not outside of it? This needs to happen on the MouseDown event of the label.How do I make the object "stick" in its current position? (From this, I can probably figure out how to make it return to its original position on my own.
