Hi,
Any of you know the property in wich the user can select the printer to print the report.
thanks
|
|
|
|
|
most likely what you're looking for is the printoptions property of the reportdocument object. there's also the standard printoptions class under crystaldecisions.crystalreports.engine namespace, but the reportdocuments printoptions property is set to read only in the reportdocuments implementation. so all you have to do is set the printername property.
Dim rd As New CrystalDecisions.CrystalReports.Engine.ReportDocument
rd.Load("myDocumentTemplate")
rd.PrintOptions.PrinterName = "myPrinter" hope this helps.

Hi all,
How can i convert an object wich contains a date value into a string value.
Thanks,
|
|
|
|
|
by an object which contains a date value do you mean an actual date object or an object which has a property "X" which is a date?
regardless, just use the .ToString method that's implemented on any object. if the object itself is a date then use myDate.Tostring(). for an object which has a date property, just use myObject.DateProperty.ToString().
there are also a few overloads of the ToString method which will acccept formatting options which will help you format the resulting string value in a more useful way. you can find those here.

Hi,
I am aware that DDE is not supported in VB.NET, but I wanted to try to get it working anyway. It seems to me that the easiest way to get it working would be to create an instance of a VB6 Textbox within a .NET application. The problem I ran into is that the compiler tells me that the constructor for the VB6 textbox is private, and can not be used.
If I try to take out the "New" statement, I get a Null reference exception.
I am adding a reference to Microsoft Windows Common Controls to get access to the MSForms Namespace.
Thanks.

The easiest way is to create a VB6 DLL or a VB6 UserControl that encapsulates everything that you need to do. Then declare public methods as needed to run the process from your NET application. Import the DLL or OCX into NET and you can essentially run your VB6 code as unmanaged code from within a NET project.

Thanks.
I was in the process of trying to basically do that, but was hitting a couple of snags (a little out of practice on writing OCX). At least I know it can be done.

I am trying to recognize text from a recorded wav file.
I use MS Speech SDK 5.1 and VB.Net.
Here's my project . It compiles OK but i get nothing as a recognized text.PLEASE HELP!
I have an initialise function ,an openstream function to open the file i want and the other important function is the RecoContext_Recognition which is called when a recognition event is created.
What am i doing wrong?!?!?
Imports SpeechLib

Hi.
I am coding a progam where I want the Context menu to CLOSE if it is already open and you press right mouse button again.
This is something that seems VERY hard to acomplish.
The code below manages to do it 2 times, but when you right click with an open context menu the 3 time, then you get a context menu even tough I do NOT want it:
Private Sub ListView1_GetMenu(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseUp
ListView1.ContextMenu = Nothing
If contextIsActive = True Then SendKeys.Send("{ESC}")
' Checking the Mouse right Button
If e.Button = MouseButtons.Right Then
Try
currentItem = sender.GetItemAt(e.X, e.Y)
If Not currentItem Is Nothing And contextIsActive = False And ListView1.ContextMenu Is Nothing Then
Me.ContextMenu1.MenuItems.Add(Me.MenuItem1)
ListView1.ContextMenu = Me.ContextMenu1
ListView1.ContextMenu.Show(sender, New Point(e.X, e.Y))
contextIsActive = True
ElseIf contextIsActive = False And ListView1.ContextMenu Is Nothing Then
MenuItem1.Text = ""
Me.ContextMenu1.MenuItems.Remove(Me.MenuItem1)
ListView1.ContextMenu = Me.ContextMenu1
ListView1.ContextMenu.Show(sender, New Point(e.X, e.Y))
contextIsActive = True
Else
SendKeys.Send("{ESC}")
Me.ContextMenu1.MenuItems.Remove(Me.MenuItem1)
Me.ContextMenu1.MenuItems.Remove(Me.MenuItem2)
ListView1.ContextMenu = Nothing
contextIsActive = False
End If
Catch
Me.ListView1_GetMenu(sender, e)
End Try
End If
End Sub
Private Sub contextMenu1_Popup(ByVal sender As Object, ByVal e As System.EventArgs) Handles ContextMenu1.Popup
If contextIsActive = False And ListView1.ContextMenu Is Nothing Then SendKeys.Send("{ESC}")
End Sub
As you can see from the code here I have LOTS of different ways for the damn context menu to close. None of which seems to work.  I really REALLY need to get this to work. It HAS to work. 
PLEASE help!

Hello Anders
I was wondering if you ever got an answer to your above question. I am having the same problem. If so could you post your resolution.
Thanks

Hi everybody. I got a simple question about loading a DLL in a VB 6 (or .NET) Application. This doesn't seem to work right. I am trying to find some way of loading a DLL without specifying the full path and without the DLL being located in the \Windows folder. For example when you have the DLL in the same folder with the Application. I tried only specifying the DLL like:
Public Declare Function SomeFunction "Somedll.dll" () as Long.
This doesn't work. Probably it looks for it in the Windows folder. As I read in the MSDN documentation it should look for it first in the Application folder, but this doesn't happen as it seems.... To complicate thing worst, I can't specify the path for the Application right there because I get a compilation error:
Public Declare Function SomeFunction App.Path & "\Somedll.dll" () as Long. '-----> This doesn't work.
I saw this in a book:
Public Declare Function SomeFunction ".\SomeFolder\Somedll.dll" () as Long.
So I tried:
Public Declare Function SomeFunction ".\Somedll.dll" () as Long.
This ain't workin' either. Anybody got a clue? : )
Thanks! : )

You'll never get it to work this way because it's a compile-time only declaration. It can't be modified at run-time.
I wish I could tell you more but I just got called out of the office... Sorry!

Hi Dave : ). There's no rush for me right now.... I was just wondering if I could link directly to a DLL in my Application's folder, rather than storing it in the Windows folder. It seems that I will be forced to save it in the Windows folder... but even so, how can I know where will the future users of my Application have their Windows folder? I mean, there's no guarantee that VB will find the DLL if I put it there right??
Anyway... what do you think about this piece of code? I found it in a book about Hooks and Subclassing in Visual Basic...
Public Declare Function SomeFunction ".\SomeFolder\Somedll.dll" () as Long.
What does that path mean? That the "somedll.dll" file is located in the SomeFolder subfolder of Windows or of the Application?
Thank you.

Hello everybody. I'm trying to make the contents of a textbox, if they don't fit in a page to wrap and use the line underneath etc etc.
So far i can clip the string in the given rectangle i have indicate with the setclip command. Other than that i can't make it work. Here is a part of the code:
'Create string to draw.
Dim drawString As String = txtComment.Text
Dim drawString1 As String = imageToLoad
Dim drawFont As New Font("Arial", 0.4, FontStyle.Regular, GraphicsUnit.Millimeter)
Dim drawFont1 As New Font("Arial", 0.6, FontStyle.Regular, GraphicsUnit.Millimeter)
Dim drawBrush As New SolidBrush(Color.Black)
' print filename
Dim drawPoint As New PointF(0.0F, -27.0F)
'print comments
Dim drawPoint1 As New PointF(0.0F, 90.0F)
If chkComment.Checked = True Then
e.Graphics.SetClip(New Rectangle(0, 0, 100, 100))
e.Graphics.DrawString(drawString, drawFont1, drawBrush, drawPoint1)
End If
e.Graphics.DrawString(drawString1, drawFont, drawBrush, drawPoint)
' There are no more pages.
e.HasMorePages = False
The textbox in question is the txtComment.Text. Any help please?
Thank you
Still trying to find the way

If you use the DrawString variant that takes a Rectangle, it will wrap the string for you.

Thank you Christian. I used
Dim LayoutRen As RectangleF = New RectangleF(0, 90, 100, 300)
e.Graphics.DrawString(drawString, drawFont1, drawBrush, LayoutRen)
and it work like a charm. Thank again!

Is there a easy way of saving the state of the TreeView. When you add or delete a node in the TreeView, It collapses the nodes which I don't want.

Hi all,
I've a select request, with the resulset i create a dbf file, but i've a problem with the datetime data, because i need to specify the date format i nedd (dmy) in the insert request. I can't use at the begining of the program the instruction "set date to dmy", becase the class that i use to execute q query, doesn't support the instruction. So, any of you know how to specify the date format??
Thanks

I'm binding the data to datagrid in vb.net, and the first column is the entity_id, I don't want it to show in the datagrid, but I need to pass the entity_id to another window when the current row is selected. The entity_id is showing in my first column in my datagrid, how can I get the entity_id without showing the entity_id?
Thanks!

Hi,
create a tablestyle for your datagrid and set it's mappingname appropriately. then create a columnstyle for each field you want to display in the datagrid.
on the backend you can still access everything that you have in the datagrid, but only show what makes sense to the end user.

thanks, Jim..
Actually, I tried to use this code
DS.Tables(0).Columns("entity_id").ColumnMapping = MappingType.Hidden
but the problem is when I click the row and need to pass the entity_id column value to other form. then it gave me error "Specified argument was out of the range of valid values. Parameter name: columnIndex."
this is my function to get the value from the datagrid.
Public Function GetSelectedRows(ByVal dg As DataGrid) As System.Collections.ArrayList
Dim al As New ArrayList
Dim cm As CurrencyManager = Me.BindingContext(dg.DataSource, dg.DataMember)
Dim dv As DataView = CType(cm.List, DataView)
Dim idCol As Integer
idCol = 5
Dim i As Integer
For i = 0 To dv.Count - 1
If dg.IsSelected(i) Then
al.Add(dg.Item(i, idCol))
End If
Next
Return al
End Function
and the idCol = 5 is the column of entity_id.
Do you have any idea for this?
Thanks!
Lisa

no problem lisa,
is there a particular reason why you're trying to return an arraylist? why not just return the dataview with the selected rows?
if i had to guewss, i would say that the exception is being thrown when you're trying to add to the arraylist. most likely because your datagrid doesn't have a column at index 5.

I fixed the problem, I set the column width to 0 in dataGridTextBoxColumn..
