While dragging a table which has a primary key from the dataset in my project onto a form to create a datagridview I get an error. The tableadapter for the table has an Update command in it. This is the error:
An error occurred while performing the drop:Code generation for property 'UpdateOrder' failed.Error was: 'Type'Action.Action2DataSet TableAdapters.TableAdapterManager +UpdateOrderOption' is not available in the target framework.'
Given that the tableadapter has an update command in it (which I did not change) .
I am making a array (unknown value) into a grid for a game of pairs (where you must get both of the cards). So far I have specified the array to a specific size of either 6, 6 10,10 or 16, 16. using a button. The selection is defined from the button as specified before Dim NumberOfCards(Selection) As Integer Dim NumberOfCards(Selection) As Integer Now I have a panel box which I want to add the number of rows / columns as the array sizes which I cannot do. But also add a image specific to all of them.
ok wot i want to do making a huge program got a error code in the setup wot i have done is made a folder placed it in program files and said to visual basic basically to start the program from there with the code process.start witch has worked but i need the setup to place the folder in program files or its not going to work coz all the files are in therend this is the error im getting Error2Could not find file 'C:Program Filessony vegas 10 and 8 with new blue effects big pack 2011vegaspro11.0.510_32bit.exe' 'Not enough storage is available to complete this operation.'c:userselfenliedtopfan5documentsvisual studio 2010Projectssony vegas mega pack setupsony vegas mega pack setupsony vegas mega packsetup.vdprojsony vegas mega pack setup
This is in a BindingNavigator. I'm trying to get it to save to the database when i click the Save button. This is what I have so far:

It's telling me "Object reference not set to an instance of an object." on the dsNewRow declaration, I have no idea what that means. That same code (aside from different names) works fine another another project.
I have a DataGridView object to which I've bound a list of objects (of type Asset) returned from a database query.I'm programming in VB using Visual Studio 2005.I want to grab two copies of the bound object (calling them oldAsset and newAsset) from the selected row in the DataGridView, update newAsset based on input from other controls on the form, and pass both oldAsset and newAsset to a function that will update the appropriate record in the DB.I try to grab the two copies like this:
Dim currentRow As DataGridViewRow = Me.AssetDataGridView.CurrentRow Dim newAsset As Asset newAsset = currentRow.DataBoundItem
[code]....
Opening a watch window on oldAsset and newAsset indicates that the appropriate values are pulled at this point. But when I try to change a property of just newAsset, like
I'm a huge music person (got my own lil record thing going) but I'm wanting to design a program that would make music in my way. I have a decent amount of background knowlege of Visual Basic and Java I'm just wondering how could I execute this whole project. The Project is making a MPC Sampler. MPC is a drum machine; a machine with buttons that once you press it that it will play a sound from a drum (ex: snare, kick, tom, ect.) . So I would want to make some pads on my program that each have their own sound. Total of 16 pads. Which the design wouldn't be hard to make nor would the functionality of it having the play back sound (in my opinoin it wouldn't be hard atleast). But the thing is I wanna map out these pads to number keys on the number pad or keyboard. I'm not so sure how to do that. But that's all the easy stuff...
Also finding information is making a sound directory. What I mean by this is that I want to make a User Interface that will open up a file directory of sounds and the user can select what "kick" or "snare" sound he may want for the kick or snare pad. I don't know how to do that or even know what to search; neverless I don't know if this whole project idea is a good idea for Visual Basic or another programing language.
Also LATER ON I am wanting to add a record and export function that alows users to..well...record and export their beat or instrumental ha. That doesn't seem too too complex (mainly due to the fact that all it needs to do is record the users key strokes and then show them and play the sounds, but obviously it would get more complex than that.)
Here is an image of one of many MPCs but one with a directory - [URL]
I have a DataGridView with a panel above it, that contains a group of textboxes above each column. My DataGridView has a horizontal scroll bar. What I want to do is when the DataGridView scrolls horizontally, scroll the panel with textboxes above it, so they stay aligned.I tried handling the DataGridView's scroll event, but I'm not sure what to do with it.
This should create a desktop shortcut but instead it spits out an error that is because of the quotes inside quotes. They need to be there, I know this is the problem as I have tried without them and it has worked. Another problem though is that it creates the shortcut (when Idon'thave quotes in quotes) but wraps the whole TargetPath in quotes making the shortcut unusable. Here is my code:
Dim input As String Dim s As String = Environment.GetEnvironmentVariable("UserProfile") input = TextBox1.Text
Part of my assignment is to check if input to Group Number and Number of Units are correct input by making error handling exceptions...
I have to check the following: a) group number is neither 501 nor 062 b) number of units are NOT numbers c) number of units is NOT a positive number
So my first question is, am I checking correctly? 2nd question is, How do I make sure my Exceptions will pertain to their correct respective things (a, b, and c.. above)?
I wrote an application last year which has been running fine on an XP Pro machine since then. Recently I installed the application on a PC running Windows 7. I am now experiencing the following error[code]...
ON Dim range As excel.Range = xlWorkSheet.Range("B2:" & alphabet(headerText.Length) & (items.Length + 2).ToString) Imports excel = Microsoft.Office.Interop.Excel
I may have missed the solution to this problem, but in my database I have 2 columns that cannot be null and a system.NoNullAllowedException message is displayed if they are mt. I want to change this message to simply indicate that the cell cannot be null, instead of the huge message with all of the information which is of no use to the user. I cannot seem to find where to change this message. When the exception is thrown I would like to see the message say something like "Empty cell not allowed".
I have a datgridview with a checkbox that keeps giving me an error. I have checked the data type in SQL(2008) table and I have it set to CHAR(1), NULL = Y, Default value = ('N'). Image attached that shows the error.
The data loads into the grid except for the checkbox state (checked - not checked)Here is my bindings and add column section. Note: The grid will only display info. Text boxes and a checkbox above the grid will actually be the input source.
I have a d.g.v. with two columns. One is set as date and the other is set as decimal. If there is a row and a number is typed in the decimal column, you can delete it and leave the cell empty. However, the program will not let me delete the contents of a date cell and leave it empty. It just gives me the default error dialog saying that I need to put the contents in proper date form and it doesn't let me leave it blank.
How can I make it so that it allows me to leave the cell blank?
I have a datagridview and all its columns are set to Double Datatype. The problem is when I changed the value of cell and try to sort the column, it shows me an error "Object must be of type Double." I check each cell but all its values are number and I can sort all the columns before I edit one cell. But when I tried to change the value of only one cell and sort the columns, the errors will show. Its weird because I only removed 1 digit of the cell value and I cant sort at all.
Code: Dim col As New DataGridViewTextBoxColumn col.ValueType = GetType(Double)
I created a DataGridView called grid_LivingBenefits.Each time a cell is going to be edited, the program will validate that cell.Now, I have two subroutines that take care of that validation.these are: ValidateDataType() and ValidatePrimaryKey()
at the DataGridView CellBeginEdit, the program checks for which cell the user is editing.at the DatagridView CellEndEdit, the program calls the subroutines for validation. If an input is invalid, I want the program to show an errorProvider on that cell.I used MessageBoxes first to check whether the validations are working and I got no problem there. but when I tried to use errorprovider instead of a messagebox, there's a blue zigzag line under the grid_LivingBenefits.CurrentCell
Private Sub TextBox1_DragDrop(ByVal sender As Object, _ ByVal e As System.Windows.Forms.DragEventArgs) Handles DataGridView1.DragDrop If e.Data.GetDataPresent(DataFormats.Text) Then

But when mouse hover to datagridview, the mouse symbol did not change. It should have to be Copy symbol but It did not. Please tell me why and how can i resolved it.
in the GotFocus event of that datagridview.But when i run and try to enter some text in a cell, then press the DOWN button to go to the next cell but there is a NullReferenceException.
I am getting an unknown error when I access one of my datagridviews. I get this error when I go to the tabpage where there is this datagrid and also when I put my mouse cursor over it.I don't know how to fix this because I don't know which code cause it. When I step through everything is ok, this error occurs at run time but doesn't show where and doesn't even stop the program.
i got this error in my code when the program runs i dont know what am i doing wrong Datagridview Default Error Dialog The Following exception ocurred in the datagridview System.InvalidOperationException: Binding Source cannot be its own data source.
I am populating my datagridview as such: Private Sub LoadDatagridview()
Dim lf As New IO_LogFile If Not lf.DataFileExists Then WriteLogInfo("Utilities.DisplayUserlog.LoadDatagridview", "Log files does not exist for " & combobox_CompanyId.Text & ". Please select another company.", True, MsgBoxStyle.Critical) Exit Sub End If
[Code]...
My data displays without using everything in the 'with datagridview_Userfile' but I need to format the screen. I used this code in another program and it's identical and has no problems so I am bewildered.
