Hello Gurus...
I want the exiting excel file to open it, format it and print it.
opening and formating part I have ( mostly) done ... but to printing giving me problems.. when the file get print, there are lots of empty pages because of the last cell.
let's say, the sheet contain only two cells that has some data. the first cell is A1 and the last cell is z130 and there are no data in the cells between first and last cells.
So when I call PrintOut method it prints all the empty pages.
I'm trying to set the print area for the excel sheet because I don't want to print empty pages. But how can i set the print area only to print that two cells???
I tried look every cells whether if it is empty or not, if empty don't do anything but if not empty, set the range and set the printarea... the following is my code..I know it is wrong but don't know how to fix it
<br />
<br />
Function SetPrintArea(sheet As Worksheet) As Worksheet<br />
Dim r As Range<br />
Set r = sheet.UsedRange<br />
<br />
Dim newRange As Range<br />
Dim i As Integer<br />
Dim j As Integer<br />
<br />
For i = 1 To r.Rows.Count<br />
For j = 1 To r.Columns.Count<br />
If Not Cells(i, j).Value = "" Then<br />
newRange = newRange(Cells(1, i), Cells(i, j))<br />
End If<br />
Next j<br />
Next i<br />
newRange.Cells.Select<br />
sheet.PageSetup.PrintArea = Selection.Address<br />
Set SetPrintArea = sheet<br />
End Function<br />
Thanks

okay, I'm gonna ask the obvious question.... why are the only two cells in the sheet with the data so frikkin' far ????. That's gotta say something bout the design!
the Range object also accepts parameters in the form of a string, like so :
"A1:C5"
The above parameter would include everything from cells A1 to cells C5
But if you wanna do composite ranges, then the following string:
"A1:C5,D12:G7"
would include everything from the first string as well as everything from cell D12 to G7 and nothing in between.
I assume you could solve your problem by constructing the composite range string before hand, then pass it into the Range object
Hope that helps

You're damn right.. why do they do so?? Can't they just insert the information into the closer cells?? I, myself, want to know why they do that.. my job is to print that excel file..minimizing the number of pages that will print as possible.
Thank you for answer SMC, So how can i get the position of the cell?
Thank you

you're looping method seem to work fine.... just don't assign the cells into the range yet. Convert into the string version first, then after evrything has finished looping, assign the string into the range

Hi,
I've created a .net Windows forms user control that is housed within IE. All the methods of the usercontrol work fine, but I can't get the events to filter through to IE.
I've read quite a bit about both the new event model in .net and how you need to explicitly create an interface in order to expose events to COM, however, after trying all sorts of examples, I just can't get it to work.
The code currently looks like (having removed the system generated code):
====================================================================
Option Explicit On
Option Strict On
Imports System
Imports System.Runtime.InteropServices
'Public Delegate Sub newCallDelegate(ByVal URN As Integer)
'Step 1: Define an event sink interface (ButtonEvents) to be
'implemented by the COM sink.
<guidattribute("a59b958d-b363-454b-88aa-be8626a131fb"), _
interfacetypeattribute(cominterfacetype.interfaceisidispatch)=""> _
Interface WebflowEvents
Event newCall(ByVal URN As Integer)
End Interface
'Step 2: Connect the event sink interface to a class
'by passing the namespace and event sink interface
'("EventSource.ButtonEvents, EventSrc").
<classinterface(classinterfacetype.none)> _
Public Class UserControl1
Inherits System.Windows.Forms.UserControl
Implements WebflowEvents
Public Event newCall(ByVal URN As Integer) Implements WebflowEvents.newCall
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MsgBox("Firing")
RaiseEvent newCall(1234)
End Sub
End Class
=================================================================================
I REALLY need to get this to work, otherwise it's back to registration of a COM wrapper.
thanks

I have a complicated question, so if i dont explain it properly, or dont supply enough information, please let me know! I have 3 datacombos - 1 for product type and 2 for price Descriptions. for each combo, i wish to populate a column in the datagrid. for the first column, products are populated based on the product type chosen and prices are populated (relating to the products) based on the price descriptions chosen. This would be fine if it was only the product type and 1 of the price combos that i was using but the fact that i am using 2 price descriptions. ( i am using the same fields for comparison purposes). is there anyway i can get around this - my SQL statement isnt working( due to the fact that teh same field is being used twice). do i need to use 2 Adodcs? is it possible to populate a column of the datagrid from a SQL statement? you will see the relationship between the tables here:
Product Type: TypeCode, TypeDescription
Product: ProductCode, ProductDescription, TypeCode
Price: PriceCode, ProductCode, Price
PriceDescription: PriceCode, PriceDesc
Any help would be greatly appreciated!

I just start to work with VB.NET and i designed a form that allows me editing customer records.
The code is as follows :
Private Sub BindingFields()
con = MyConnection.GetHandler()
Mydataset = New DataSet()
MyAdapter = New SqlClient.SqlDataAdapter("select * from client", con)
MyBuilder = New SqlClient.SqlCommandBuilder(MyAdapter)
MyAdapter.Fill(Mydataset, "client")
TextBox1.DataBindings.Add(New System.Windows.Forms.Binding("Text", Mydataset, "client.r01_codcli"))
TextBox2.DataBindings.Add(New System.Windows.Forms.Binding("Text", Mydataset, "client.r01_adrcli"))
TextBox3.DataBindings.Add(New System.Windows.Forms.Binding("Text", Mydataset, "client.r01_tel1"))
TextBox4.DataBindings.Add(New System.Windows.Forms.Binding("Text", Mydataset, "client.r01_nomcli"))
TextBox5.DataBindings.Add(New System.Windows.Forms.Binding("Text", Mydataset, "client.r01_tel2"))
TextBox6.DataBindings.Add(New System.Windows.Forms.Binding("Text", Mydataset, "client.r01_fax"))
TextBox7.DataBindings.Add(New System.Windows.Forms.Binding("Text", Mydataset, "client.r01_datcre"))
TextBox10.DataBindings.Add(New System.Windows.Forms.Binding("Text", Mydataset, "client.r01_remcli"))
CheckBox1.DataBindings.Add(New System.Windows.Forms.Binding("checked", Mydataset, "client.stop_serv"))
'da.Fill(Mydataset, "Categorie")
'ComboBox1.DataSource = Mydataset
'ComboBox1.DisplayMember = "categorie.libelle"
End Sub
and the code of the AddNew button is as follows :
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
AddRecord()
End Sub
'This routine add a blank record
Private Sub AddRecord()
Mode = "A"
Try
Me.BindingContext(Mydataset, "client").EndCurrentEdit()
Me.BindingContext(Mydataset, "client").AddNew()
TextBox1.Text = Getautocode()
TextBox4.Focus()
Catch eEndEdit As System.Exception
System.Windows.Forms.MessageBox.Show(eEndEdit.Message)
End Try
End Sub
Someone can tell me for why the fields don't become empty when i click on the addnew button .
whereas, when i disabled the line :
CheckBox1.DataBindings.Add(New System.Windows.Forms.Binding("checked", Mydataset, "client.stop_serv"))
the code works correctly.
Thank you very much.

i am trying to perform form validation on my Order Generation form. In testing for a valid quantity, i use the following if statements
ElseIf (Me.txtQuantity.Text = "") Then
MsgBox "Please enter a value for Quantity"
ElseIf Val(iQuantity) = 0 Then
MsgBox "Please enter a value for Product code"
ElseIf IsNumeric(iQuantity) = False
MsgBox "Please enter a value for Product code"
However, is doesnt seem to recognize these statements as when i dont enter a value for quantity, a message box should pop up but instead i hit a runtime error saying "type mismatch"...why is this - is there anything i can do about it? Thank you in advance!
|

I'd recommend the following:
- create a local variable based on a Trim() of the txtQuantity.Text
- check length first
- next, check for a false on IsNumeric()
- only then look for certain integer values
HTH limit further bugs
btw, which line are you getting the type mismatch from?
Cheers,
Simon

Here is a basic structure of my code:
Private Sub cmdConfirm_Click()
With Adodc3.Recordset
Do Until .EOF
.MoveFirst
Call Save(iOrderNo, strCode, strDesc, iQuantity, iFullPrice)
.MoveNext
Loop
End With
Function Save(iOrderNo As Integer, strCode As String, strDesc As String, iQuantity As Integer, iFullPrice As Integer) as boolean
.....validation statements and inserts
If Val(DataGrid2.Columns("Quantity").Value) > RS("Quantity").Value Then
Call BackOrder(strCode, strDesc, iQuantity)
End If
Save = True
Function BackOrder(strCode As String, strDesc As String, iQuantity As Integer) As Boolean
....validation and inserts
BackOrder = True
To step through the code briefly, when the command button is pressed, a save function is called (for each row in the datagrid), which performs the necessary validation and saves to the database, this also calls another function - BackOrder, which enters products in a backorder if necessary. I hope the information given is sufficient, and if not, please let me know. The problem occurs when the project is run, there must be something wrong with the loop as it runs through the first row twice, upon which a bug is thrown, without ever moving onto the next row...why is this - how can i make it run through all the rows? Thank you so much - any help would be greatly appreciated!

Loop
This code:- Moves to the first record;
- Saves the record;
- Moves to the next record;
- Goes back to the start of the loop;
- Tries to move to the first record;
- Throws an error because you have a forward-only recordset;
Change the loop to:
Do Until .Eof
' TODO: Get these values from the recordset!
Call Save(iOrderNo, strCode, strDesc, iQuantity, iFullPrice)
.MoveNext
Loop

I wrote a Multithread ARCNET-Driver in VC++. It receives Data Packets from the NullStackDriver. My VB6 Application opens an controls the Driver. So far so good.
The VC++ DLL is managed by serval Events (CreateEvent(), SetEvent(); ResetEvent(); WaitForSingleObject()...)
On receiving a Complete DataPacket i would like to send a additional Event ex. EVENT_RX to signalize my VB6 that it can read the Packet from the Queue and prozess it.
How can I make my VB6 Application to react on this EVENT_RX ?
Thanks for any Inputs!

I used to use the sourcesafe as my source control software in previose version of Visual Studio. What is used now with the .NET for source control?
If it is the Sourcesafe, what version (I found in my MSDN version 6)?
Thanks

Visual Studio.NET can use VSS also. You should use 6.0c (which is the version that came with VS.NET Enterprise) since, if I remember correctly, it had some file types changes that help it work with VS.NET. 6.0c should be in the MSDN disks...

I have a program that plays multiple WAVS at the same time. What I cant figure out how to do is adjust the volume levels and panning for each individual WAV during playback. The only info Ive found is about changing the master WAV device volume. Can someone shed some light on how I can change the volumes and pans of individual WAV files (all of which are playing through the main WAV device output)?
Thanks!

Hello, I have the following problem: A class with a property called MyCollection which is, obviously, a collection. The collection MyCollection contains items of type MyItemCollection:
MyClass
property: MyCollection as CustomCollection
CustomCollection
property: MyItemCollection as SecondCustomCollection
Now, I designed custom editors for both "SecondCustomCollection" and "CustomCollection". They both work perfectly, but... When using the collection editor for MyCollection, I click "Add Item" and a new MyCollection item is created. The next step would be to call the editor for the MyItemCollection by pressing a button. That button should programatically call the editor for the second class... This is where I got stuck... Look:
cd is the MyItemCollection:
Dim tp As Type = cd.GetType ' I get it's type
Dim ac As AttributeCollection = t.GetAttributes(tp) ' I get it's attribs
Dim ed As EditorAttribute = CType(ac(GetType(EditorAttribute)), EditorAttribute) 'I get the editor
If Not ed Is Nothing Then ' found it?
Dim te As TypeEditors.ColumnDefCollectionEditor ' this is the editor type
te = New TypeEditors.ColumnDefCollectionEditor(GetType ColumnDefinition.ColumnDefinitionCollection))
Now, the logical call to edit the value would be:
cd = te.EditValue(context, provider, cd)
to launch the editor with the current object and return the same object with the changes.
The place I got stuck is finding the context and the provider. Here is what I tried:
Dim sv As System.ComponentModel.Design.ServiceContainer = New System.ComponentModel.Design.ServiceContainer()
sv.AddService(GetType(IWindowsFormsEditorService), Me)
te.EditValue(cd.GetType, sv, cd)
But it does not work... I get an error at AddService first of all...
So, my question is how can I get the IServiceProvider and the ITypeDescriptorContext required to programatically call my custom editor?
Any help would be appreciated!
Thank you,
Best Regards,
Iulian

i have performed validation and populated a datagrid via a command button and using a "pseudo" (temporary) table called OrderDetails2. Now I wish to save the details to the proper table (ie OrderDetails), as every row in the datagrid as to be looped through to achieve this, I am using this code:
Dim iRowCount As Integer
'Dim row As Integer
iRowCount = Adodc3.Recordset.RecordCount
For DataGrid2.row = 0 To iRowCount
Call Save
Next row
the code in the save function is:
Dim iOrderNumber As Integer
iOrderNumber = RS.Columns("OrderNo")
Dim strProductCode As String
strProductCode = RS.Columns("ProductCode")
Dim strProductDesc As String
strProductDesc = RS.Columns("ProductDesc")
Dim iProductQty As Integer
iProductQty = RS.Columns("Quantity")
Dim iOrderPrice As Integer
iOrderPrice = RS.Columns("Price")
Dim nSQL As String
'inserting the order into order detail
nSQL = "Insert Into OrderDetail (OrderNo, ProductCode,ProductDesc, Quantity, Price) " & _
" Values (" & iOrderNo & ", '" & strCode & "', '" & strDesc & "', " & iQuantity & ", " & iFullPrice & ")"
Set RS = Conn.Execute(nSQL)
however, when run, a compile error is thrown "variable required - can't assign to this expression" (referring to the datagrid.row)
what can i do to fix this or is there any different way to can achieve the same functionality? Thanking you!

|

|

Set RS = Conn.Execute(nSQL)
I think the above statement is the problem ..
you execute a statement that inserts data in a table and does not return a recordset ..
try using :
Conn.Execute(nSQL)

similiar to the manner in which you can have a click/LostFocus/GotFocus etc event with textboxes, is there anyway you can have a "tab event" in a specific column of a datagrid? (ie when tabbed across, an action happens in another column)? Thanking you!
