The list view will be controlled by a date or calendar control. Haven’t decided whether to use a stored procedure. Since I use a select statement with a case argument. Still not getting the look I want.
It would be similar to a cross tab table used in ms access.

Hey Ole123
Well I will leave the front end to you, but if you choose to go with a stored proc then here is the basic layout including getting the headers...
CREATE PROCEDURE MP_CB_Get_CallBacks
AS
-- V1.0.0 : Super Winsock : 4 March 2002
-- Returns the Column names and width for the grid.
-- It also returns the data.
SET NOCOUNT ON
--Returns the Column names and it's width.
-- 1st is the column name & 2nd is the column width and so on.
SELECT
'Id',
0,
'Student_Name',
0,
'Teacher_Name',
2000,
'Subject',
1500,
'Time',
1500,
'Date',
1500
SELECT
[Id],
Student_Name,
Teacher_Name,
Subject,
Time,
Date
FROM
?Table
SET NOCOUNT OFF
GO
/* Hope this helps?
|
|
|
|
|
I forgot to add that the student data is a seperate table as well as the teacher's data. So I have a Student and Teacher table. I don't think I could use a stored procedure.
|
|
|
|
|
Well thats no problem?? Just use a JOIN statement to join the teacher and Student tables... This can be done in a sproc.
If you really get stuck, just post the Student and Teacher Tables structures and what you want to get out of them in your record set, and I will gladly help you write the sproc.

Still a little stuck so i still need help. I posted a sample tables in the post and what the display should look like...
Thanks for all your help. I have been kicking my self for about two weeks trying to get the display i want with no success.
MSSql does not use the Transform sytnax so i'm not able to create the crosstab look and feel for my listview form in vb.net.
Thanks again for all your help

Hey Ole
Well your post of the tables is somewhat confusing

1.Are your headers always going to be the same? If so then you can just hard code them.
2. Just tell me what the headers are and from there I can get the info from the tables.
3. In a listbox you have to use COURIER NEW as your font, else the spacing is never going to be right.
4. You have to pre-determine your column lengths before you populate the listbox. IE: If you have a column named First_Name, thats 10 characters, and the name is Ole. You will have to add 7 spaces after the name to make the next column's data in line with its header.
Probably a bit confusing the way I explained but just tell me the column headers and I will write the sproc. Thats the easy part.
You will have to do the front end.

The columnheader will always change. So it's more of a dynamic columnheader. Depending on the Day of the week. There could be 5 or 3 or 10 teacher who have classes to teacher at different time of the day.
The Teacher's name will be the columnheader
Basically i'm trying to build a cross-tab query
Teaher's names across the top
The time is in the left column down
and student name
Teacher_Name Teacher_Name Teacher_Name Teacher_Name
Time Student_Name Student_Name Student_Name Student_Name
C1 and R2 = Student_Name C2 and R2 = Student_Name
C1 and R3 = Student_Name C1 and R3 = Student_Name and so on
The only way i can build a cross-tab query is in crystal report.

My main form has a toolbar, menu, docking windows on the left, top, right and bottom - i now want to change the toolbar and menu for a third party control - how do I get the new toolbar and menu onto my form (I cant change the docking on the docked windows as they have to be docked even at design time)

i want to be able to update info in a datagrid and then save it to my database, any ideas?
|
|
|
|

Lots of them. But your going to have to get alot more specific about what your want to do and how you want to do it...

i made a basic program that adds info to an acess database and displays it in a datagrid, i want to edit the info though the grid and update the database....
|
|
|
|

you can find very usefull documentation at Visual Studion.NET help.
concisely you must use and Update column at the DataGrid and use the Update method of the DataSet you used to create the DataGrid to update the data to Access database.
if you won't find any example at vs.net help i can send you a small sample code about updating database with dataset

I would like to know if there is any tool available for Visual Basic 6.0 which can reproduce MATLAB's 3D surface plotting, like the fill3 MATLAB function?

Is it possible to set a form's location and size before displaying it? I have a couple of resizable forms in my current project. I'd like to have the app remember the size and location of the forms when the user last closed them.
|
|
|
|
|
I'll leave the part about saving and retrieving the values up to you since there are so many methods of saving these values somewhere...
You can set the Size, Location and StartPosition properties of the form before you call the form's Show or ShowDialog method:
Dim newForm As New Form2
newForm.Size = New Size(100, 200)
newForm.StartPosition = FormStartPosition.Manual
newForm.Location = New Point(50, 50)
newForm.Show()

|
|
|
|
Perfect. And by inserting the middle three lines into the Load event, and changing 'newForm' to 'Me', I've managed to change the main form as well. Don't worry about the saving - I've got that bit sorted out.
Thanks for your help.

Hi..I want to configure the data adapter to select all columns from a aspecific table in my database then fill the dataset with this data and do some functions on the data and then i want to display the results in a datagrid how can i do this and can i find any VB.NET code example to do it ?
Thanks
|
|
|
|
|
If you create the dataset using the Fill command of dataAdapter - for example
dtAdapt.Fill(myDataset,"TableName")
then you write:
myDataGrid.DataSource = myDataSet.Tables("TableName")

Thanks for your reply but I don't want to display all the data from the dataset I want to do some functions on some columns from the dataset and then display the results in the datagrid any idea ?
|
|
|
|
|
maybe you can create a DataTable in your DataSet containing the results
Dim workTable as DataTable = New DataTable("Results")
you fill the DataTable "Results" with the results of your functions maybe with a Do While Loop or a For Next loop from the original table and then you add the DataTable in the DataSet
myDataSet.Tables.Add("Results")
Finally you can bind your DataSet with the DataTable results
wrkGrid.DataSource = myDataSet.Tables("Results")

Hi everyone!
(sorry for posting twice, but I posted in the wrong "area"(NET Framework) earlier)
New member and also new to VB.NET I'm planning to learn it, in order to creat nice user interfaces to databases.
The problem:
I have som code for moving nodes between treviews, and everything work fine as long as there already is one node in the destination treeview (we're talking drag and drop here).
However, I want to be able to check if there is NO destination-node, and in those cases run alternativ code.
I can only make it happen if I use OnErrorResumeNext statement in the sub, but I understand that is not a good way to handle exceptions like this.
Public Sub TreeView_DragDrop(ByVal sender As Object, _<br />
ByVal e As DragEventArgs) _<br />
Handles TreeView2.DragDrop, TreeView1.DragDrop, TreeView3.DragDrop<br />
<br />
Dim NewNode As TreeNode<br />
If e.Data.GetDataPresent("System.Windows.Forms.TreeNode", False) Then<br />
Dim pt As Point<br />
Dim DestinationNode As TreeNode<br />
<br />
<br />
pt = CType(sender, TreeView).PointToClient(New Point(e.X, e.Y))<br />
DestinationNode = CType(sender, TreeView).GetNodeAt(pt)<br />
<br />
<br />
NewNode = CType(e.Data.GetData("System.Windows.Forms.TreeNode"), TreeNode)<br />
<br />
On Error Resume Next 'don't want to use it here<br />
If Len(DestinationNode.Text) < 1 Then 'error occur<br />
'If Err.Number <> 0 Then MsgBox(Err.Description)<br />
CType(sender, TreeView).Nodes.Add(NewNode.Clone)<br />
Else<br />
DestinationNode.Nodes.Add(NewNode.Clone)<br />
DestinationNode.Expand()<br />
End If<br />
'Remove original node<br />
NewNode.Remove()<br />
End If<br />
End Sub<br />
Thing is, if I don't drop the data on an existing node, "DestinationNode" has no value, but even if I try to check for Null-values an error occur, and the code stop running.
I want to be able to check for a valid value within DestinationNode, and make descision based on that, without causing an error. (IF there is no DestinationNode, THEN...)
How do a do this WITHOUT using On Error Resume Next?

Look into Try/Catch blocks...
Try
[Some code that might fail goes here]
Catch [Grab exception type here]
[Code to handle exception goes here]
Catch [Grab a different exception type here]
[Code to handle a different exception goes here]
Finally
[Code that always runs no matter what happens goes here]
End Try

You could also just check if DestinationNode is Nothing:
pt = CType(sender, TreeView).PointToClient(New Point(e.X, e.Y))
DestinationNode = CType(sender, TreeView).GetNodeAt(pt)
If DestinationNode Is Nothing Then

The "IS NOTHING" worked great!
...and I learnd something about Null and Nothing!
Thanks Again!
