VS 2010 - Database File Cannot Be Found After Adding UserControl
Aug 30, 2011
After adding a UserControl to a form which access my database I get this warning:
Warning1The database file cannot be found. Check the path to the database.
[ Data Source = C:Program Files (x86)Microsoft Visual Studio 10.0Common7IDEDatabase.sdf ]
C:UsersUserDocumentsVisual Studio 2010ProjectsProject1Project1Options.Designer.vb2160
Thing is I never had a database at that location, my database is and has always been in MyDocuments in the Project folder itself. There is nothing anywhere in my code referring to that database! When I double click it I get sent to this line in the Designers window:
Me.Controls.Add(Me.BoxControl1)
Even though I get this error I can still access my database, so basically it does absolutely nothing except drive me mad! So how do I fix this?
i'm having trouble adding an Icon for the Toolbox on my UserControl.I'm using the following:
<ToolBoxBitmap"CovButton.bmp")> _
I have CovButton.bmp added to the project and have it's build set to 'Embedded Resource'.However i can't compile it because i'm getting an error with the line continuation character saying the following "Attribute specifier is not a complete statement. Use a line continuation to apply the attribute to the following statement.".If i remove the space between the > and _ it gives me the error "Line continuation character '_' must be preceded by at least one white space and must be the last character on the line."
im making a program and it needs to load 95 files on form load.im trying to make it to if the file cant be found that it will give a error instead of a JIT debug thing. i triedadding
HTML Catch ex As Exception MsgBox("Error: " & ex.Message)
Dim myProcess As New Process() Try myProcess.StartInfo.UseShellExecute = False myProcess.StartInfo.FileName = "C:windowssystem32wuauclt.exe" myProcess.Start()
I set a background image to my project. When I run it, It comes with an error, file not found:
Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.. I do have the file, and I didnt move places. I still have it and also reloaded it in the resources.
I got a user control that has a few links, one of them is "add article". It's placed on top of the article and bottom of it. When the user clicks on it, the text changes to 'article added'.
But the text only gets changed for one of the links which has been clicked on. How can I make it so that both text changes no matter which one gets clicked?
I have a user control which I load dynamically inside a page using for...each loop calling loadcontrol.
Inside that usercontrol, there is a textbox and a button for searching.
When the btnSearch is clicked, another usercontrol will open but this time it is a popup. This popup contains the search result.
Now the problem is, if I have my program created 5 controls in the loop, the search button in the usercontrol only functions on the first display. The other 5 usercontrols loaded have search buttons that only refreshes the page instead of calling the popup.
The codes for search are inside the btnSearch of the usercontrol.
H9ow can I make the other dynamically added controls work and not only on the first instance?
I have an imagelist control in a usercontrol I made. I would like to create a property for this usercontrol, to select multiple images (in an 'openfiledialog'), and adding them to the imagelist inside the usercontrol. So, what's the type of this property? Public Property thelistofimages as [?] It should be an array of images I guess. And then in the 'set' of the property it would add all the images to the imagelist.
I have a TabControl on a UserControl. I want the UserControl to behave like a TabControl as usual (it contains only the TabControl and a Contextmenu), including Design-time behavior.I have spent the last two weeks finding out how to add the Design-time behavior and I think I have come a far way.The problem is with adding TabPages during Design-time (while the UserControl is a custom tabcontrol, it is using regular windows forms TabPages).In the Designer class, I have the following code to add a TabPage:
vb.net Dim dh As IDesignerHost = DirectCast(GetService(GetType(IDesignerHost)), IDesignerHost) If dh IsNot Nothing Then Dim i As Integer = tc.SelectedIndex Dim name As String = GetNewTabName() Dim tab As TabPage = TryCast(dh.CreateComponent(GetType(TabPage), name), TabPage) tab.Text = name tc.Controls.Add(tab)
[code]....
So it would add the control to the TabPages collection if it was a TabPage, and use the regular routine otherwise.
(I'm now using 'tc.Controls.Add(tab)' again instead of 'tc.tabCtrl.TabPages.Add')
But, I don't think the designer even gets that far because it is telling me I cannot add TabPages to my usercontrol, because only TabControls can accept TabPages... How can I make my usercontrol understand that it is a TabControl (without Inheriting from a TabControl?)
I am searching a XML file for <Asset_Number> and then adding all children to DataGridView1, i can search but i dont know how to add item to the DataGridView Also my datagridview columns are created from a txt file
this is what i have.....
this is my XML <?xml version="1.0" standalone="yes"?> <DocumentElement>
I have records in my datagridview (from database(ms sql server 2008 r2)). What i want to do is to insert the records selected by my datagridview checkboxcolumn and IF POSSIBLE automatically delete a record if the records to be inserted are equal to the records inside the database. (Hoping you got what I want to say.) For example. I have an A,B,C(child) that is under XXX(parent) in my database and I'll be inserting the A,B(child) again but it will be under YYY(parent). The old record in XXX will be deleted except C. I just want a possible DELETE STATEMENT These are what I've done so Far :
Insertion of record to database Try connectionString = "Data Source=***;" sql_connection = New SqlConnection(connectionString)
I found a custom ListBox that, strangely doesn't have an InsertAt method and I would like to add one. The custom ListBox uses an object instead of just a list of strings like a normal ListBox. I was curious what the logic behind inserting a new item at a particular index would be.The only thing I could come up with was add the new ListBoxItem at the end, then using the specified index, I could either keep moving ListBoxItem objects to the bottom, with the Add() method, from that index till the ListBoxItem at that index equals the one added, or I could use that index number in a "calculation" till I know I've moved the correct number of objects.
I'm adding records to my table which works fine. However, when I want to add a lot of records it takes some time and it looks like nothing is happening. I want to add a progressbar to show the progress.
For Each dgvrow As DataGridViewRow In mydgv.Rows progress.Maximum = mydgv.Rows.Count Dim cmd_save As New MySqlCommand("INSERT INTO ....etc", conn)
Whether I am using VB 2008 Express or VS 2010 Beta 1 Visual Basic, I get the same error: "Debugging information for 'EXCEL.EXE" cannot be found or does not match. Cannot find or open the PDB file" I have filled in the Debug Tab information: Start external program: C:Program FilesMicrosoft OfficeOffice12Excel.exe
i am having a trouble about adding a file location (e.g. c:/bla/blahblah)to a database i have my code here
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=G:\WindowsApplication2\Database1.mdb" AxWindowsMediaPlayer1.settings.volume = 100

everytime i add a mp3 file to listbox it should get the file location and pass to the database but it seems my database is empty?
My project involves making a table database that displays student number, surname, first name, homeroom, and grade avg. Through SQL commands, there must be functions to add, update, delete, search by field, and save records to the database.I have already set the database up just fine and displayed it in a DataGridView. Through the DataGridView, I was able to go to the "Add Query" area, and I successfully made the queries necessary for searching by field. However, when I try to do anything other than a search using the query builder (ie start my SQL command with INSERT INTO or DELETE FROM), I ultimately get the message "Failed to get schema for this query"For example, this SQL code (to add an entry to the database) worked when I was in the Query Builder (and the entry that it made is still in the database), but when I finally tried to confirm it, I got the "Failed to get schema for this query" message.Being unable to add entries to the database this way, I tried to do it with textboxes on a form. Each textbox will have one of the fields, and at the click of a button, they would be put into the table. My code is below. I do not know what is wrong withit. When I run it, my fields do not appear on the DataGridView immediately, but I must run the program again to see it. The time after, the entry is gone. So I am not sure how exactly such entries are to be saved.

I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.
I created a database in SQL server compact 3.5 I have a few fields in that.Later when I tried to delete one column and added so more, change was not saved. I did it all using server explorer of VB.Net. when I make the change, at that moment I can see the newly added columns but when I make dataset for this table
I am not able to add records in an Access 2007 database using VB 2010 Express Edition. I have read other posts and followed them but still I am not sucessful. I have the connection to the access database as MS Access Database, therefore it has the OLEDB connection (not the Jet 4.0). I am using the project instance in binding the text boxes to the fieldnames in the Access database. Did I miss something? I am also using Windows Vista Ultimate.
I've added multi-language support to my application by setting the Localizable property of each form to True and changing the Language property to the desired one. Then I change the Culture.
vb.net System.Threading.Thread.CurrentThread.CurrentCulture = New System.Globalization.CultureInfo("de-DE") System.Threading.Thread.CurrentThread.CurrentUICulture = New System.Globalization.CultureInfo("de-DE")
VB automatically creates the resource files and this works all fine, but now I need to do something similar for Strings and MessageBoxes, e.g. MessageBox.Show(My.Resources.Exit). Everywhere I read that I need two resource files in order to do this, but I can't find where to add a second resource file myself.
Every forum post or google search result I found says, go to 'Project -> Add Resource', but I don't have the "Add Resource" menu option. Or they say, right click on your solution and go to 'Add -> Resource (RESX)', but I don't have a "Resource (RESX)" menu option either. When I go to 'Project -> Add New Item', there's no 'resource' option in the list either. Am I blind or does VB2010 Express not have an option to add resource files manually?
Currently I am using this code to check for Firefox on a 32 bit machine
Code: Dim Firefox32 As String Firefox32 = My.Computer.Registry.GetValue _ ("HKEY_LOCAL_MACHINESOFTWAREMozillaMozilla Firefox 5.0in", "PathToExe", Nothing) MsgBox("The value is " & Firefox32)
If the value is found then the above message is fine, but if the entry is not found I want it to display a message like: "Firefox could not be found" instead of "The value is: " What code would make this appear?
