MS released the new MSChart for .net 3.5 sp1. I'm trying to get the hang of it in VS2008. One big issue I have is that if I have no data plotted the chart area axis's aren't drawn. Does anyone know a way around that? That seems like a pretty basic/common issue.

how to move current record in datagrid, i mean when i press Next record button then datagrid's data (table) also should move to next record or when i click any record in datagrid, then the current record of dataset also should move to clicked record of datagrid, so that i also may see datagrid's clicked record in textboxes in short i want to use default feature of vb6's ado control, when we bind datagrid with ado control, it worked autometically, both data grid and adodc wer connected each other at a time, so that moving next record also apears in datagrid.
Why would this code - that loads lots of VENDORS into this dataset - only show "1 of (1)" on the binding navigator?
VendorBS is the BINDING SOURCE.
Private Sub vendorLoad()
Dim connectString As String = "Server=fps-lap-szsqlexpress; Initial Catalog=Casefiles; Integrated Security=SSPI"

My system still show the "record has been added" and save/insert the data even if i chose the "no" button. I think I miss something on our codes. Should I add something?
Here's the scenario: If "Yes" (button) will be clicked, it'll save the data and clear the fields. If "no" (button), it'll clear the fields and shouldn't save anything.
Here are the codes:
Private Sub btnsave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsave.Click
If newname.Text = "" Or newaddress.Text = "" Then
MsgBox("Please fill-up all the requirements.", vbExclamation, "*** System")
Else

My Front end is VB.net 2008.I have a form. In this form, I have a menu control, this menu control has four buttons.On clicking the first three buttons, open the window with Show() event. and the fourth button open the screen with ShowDialog().Now, One by one I am clicking the button , so finally i have now four windows of this application.(Three with Show() and one with ShowDialog())Right?
Now I am minimizing all the windows with the help of Window + D Button.After this, If I use the keyboard(Alt+ Tab) keys. This is opening the showDialog window on top because , Show dialog's TopMost = True.Now I come back to my problem. That's why I cannot use the show/Showdialog overloaded menthod to pass the Me/form-id .Again, I use the keyboard(Alt+ Tab) keys, to minimized all windows. In the taskbar and Startmenu properties ,I have selected the Group Similar Taskbar buttons.This resulted in the heap of my application windows, one on the other.Now i click on one of my application window , and If I click the window other then the Show Dialog opened Window, this is not bringing the show dialog window to topMost.
Note:- There is no parent child window requirement. That's why I can't use the Show/Show Dialog overloaded method to pass the Me/Form-id
Syntax error: Missing operand after 'top' operator.on line below dg.DataSource = dsResult.Tables("aTable").Select("RowID in (select top (100) [RowID] from aTable)")
Does anyone other way to do this.
BTW the rowID is just a unique id.

View 4 RepliesI have very strange problem, here it is: I have a quite large MS Access Database (2003) containing exactly 68020 records (rows). The problem is, when i read the entire database directly toa data representation control like DataGridView or Listbox,only 66710 records are returned. The weird thing is: If i load the entire database to a in-memory datatable object, rows.count gives "correct" amount of records as expected, that is 68020What is the reason of that? Why DataGridView or other controls cannot have records more than 66710 items? Is there an internal limitation? (That's dread if there is).
View 3 RepliesI have written a code which adds some information to a database. No problem with that since the records get inside the database. My problem is that the record I added always shows up on my Search. I tried changing the variables so that none will have the same names between the two forms but it still shows.Example:
1. I added a record of a book which has an id of 1, name of Cisco, and total of 50. I added it thru the debug function.
2. I added a record of a book which has an id of 2, name of Link, and total of 30. This time, I added it directly on the database file itself.
2. I created a search button which will show records depending on the input of the user.If I type "1" for the ID, the first record will appear on the datagrid. If I type "2" for the ID, both records will appear. If I type "3" which I doesn't have any record with, the FIRST record will still appear. To summarize it, the record that I added through the program itself will always show up on the query results, no matter what I type into.

I'm fine with both C# and VB.NET..I have two tables. Authors and Books. It's a one to many relationship, Authors to Books. I'm writing a query to show how many books that each author has.[code]But in the Authors table, there are some authors without any books yet. For example, there two authors, Author D and Author E that have no books yet. I want to write query that includes all authors and number of ther books, even though they don't have any book yet, no record in the Books table yet.

I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"
