If you are using an exchange-server there are a lot of tools to add disclaimers to the outgoing mail ( normaly those use a message sink to fetch messages from the internal transport and attach these) - just search google for exchange and disclaimer ( you will find even some vb-scripts to handle the task ).

In the old Datagrid (ASP.Net 1.1) days to add a data column to a datagrid using VB.Net you used something like:
Datagridname.Columns.Add(New DataColumn("Name", Gettype(String)))
Now when I try to use this same functionality to name a column that I need to add programattically to a gridview I get this error:
Value of type 'System.Data.DataColumn' cannot be converted to 'System.Web.UI.WebControls.DataControlField'
I have tried to use DataControlField("Name")as shown here: gridview.Columns.Add(New DataControlField("Carrier FEIN")) but I get an error: 'New cannot be used on a class that is declared 'MustInherit'. So I removed the New and get the message 'datacontrolfield is a type in 'WebControls' and cannot be used as an expression.
I am at a complete loss and really need some help. I am using ASP.Net 2.0 and VB.Net 2005 - Anybody have any ideas? TIA,
Coleen

It said it suppose to be a DataControlField. DataControlField is the abstract class of TemplateField, BoundField, hyperlinkfield and etc..
<br />
BoundField bf = new BoundField();<br />
bf.DataField = "DateOfBirth"; <br />
GridView1.Columns.Add (bf);<br />

Hi Friends,
I am trying to Convert DataGrid into Excel,
My Code -------------------------------
Private Sub btnExport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExport.Click
'export to excel
Response.Clear()
Response.Buffer = True
Response.ContentType = "application/octet-stream"
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls")
'Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
Me.EnableViewState = False
Dim oStringWriter As New System.IO.StringWriter
Dim oHtmlTextWriter As New System.Web.UI.HtmlTextWriter(oStringWriter)
grd1.AllowPaging = False
Me.ClearControls(grd1)
grd1.RenderControl(oHtmlTextWriter)Response.Write(oStringWriter.ToString())Response.End()
End Sub
Private Sub ClearControls(ByVal control As Control)
Dim i As Integer
For i = control.Controls.Count - 1 To 0 Step -1
ClearControls(control.Controls(i))
Next i
If Not TypeOf control Is TableCell Then
If Not (control.GetType().GetProperty("SelectedItem") Is Nothing) Then
Dim literal As New LiteralControl
control.Parent.Controls.Add(literal)
Try
literal.Text = CStr(control.GetType().GetProperty("SelectedItem").GetValue(control, Nothing))
Catch
End Try
control.Parent.Controls.Remove(control)
Else
If Not (control.GetType().GetProperty("Text") Is Nothing) Then
Dim literal As New LiteralControl
control.Parent.Controls.Add(literal)
literal.Text = CStr(control.GetType().GetProperty("Text").GetValue(control, Nothing))
control.Parent.Controls.Remove(control)
End If
End If
End If
Return
End Sub 'ClearControls
I am getting output of Excel. But not in correct format. The Excel sheet contains data of only the First page. It shows the Paging Number down after the first 10 records. And yes i have a column of data in Greek language which is not visible clearly. I am using MS Office 2007. Any help or suggestions would be highly appreciated.
Thanks
Cheers

Surely you can use VB2005 and COM to talk to Outlook 2000 ?

How are you downloading them ? Can't you just check if any thread is still running ?

hello sir.
i simply write a class which code is below
Imports system<br />
Imports System.Threading<br />
Imports System.IO<br />
<br />
Public Class DownloadClass<br />
Public DownloadFileWithSourcePath As String<br />
Public DownloadFileWithDestinationPath As String<br />
<br />
Public Event DownloadComplete()<br />
<br />
Sub StartDownload()<br />
If Not File.Exists(DownloadFileWithDestinationPath) Then<br />
Try<br />
My.Computer.Network.DownloadFile(DownloadFileWithSourcePath, DownloadFileWithDestinationPath)<br />
<br />
Catch ex As Exception<br />
<br />
End Try<br />
<br />
End If<br />
' RaiseEvent DownloadComplete()<br />
End Sub<br />
<br />
<br />
End Class
i use above code in following procedure
Protected Sub DownloadFileInfo(ByVal sourcePath As String, ByVal DestinationPath As String)<br />
If Not File.Exists(DestinationPath) Then<br />
Dim DownLoadObject As DownloadClass = New DownloadClass<br />
Dim DownloadThread As New System.Threading.Thread(AddressOf DownLoadObject.StartDownload)<br />
DownLoadObject.DownloadFileWithSourcePath = sourcePath<br />
DownLoadObject.DownloadFileWithDestinationPath = DestinationPath<br />
'DownloadThread.IsBackground = True<br />
DownloadThread.Start()<br />
<br />
'MsgBox(DownloadThread.ManagedThreadId)<br />
End If<br />
End Sub
above procedure is called multiple time during processing.
So now the base of above coding, can i get know that downloading of all thread is complete or not?
if not can you provide me some idea or code or some links which help me

i have a datatable representing items in an order as follows
Items:
itemNum
Origin
Destination
QtyOrdered
AmountPackaged
I have a datagrid that i only want to show only the items that haven't been fully packaged i.e. QtyOrdered isn't the same as AmountPackaged. So i set its datasource to the tables default view and set items.defaultview.rowfilter = "QtyOrdered <> AmountPackaged"
However this doesn't seem to do anything as when AmountPackaged matches QtyOrdered the row never gets filtered out. any idea on why my filter isn't working?

Hi all. I am trying to save an image which i am creating in code. Everytime i call the Bitmap.Save Function i get an error "A generic problem occurred in GDI+". I have googled this for the past hour and have been unsuccessful. Her is the source code you need to understand what i am doing.
Dim bmp As New Bitmap(80, 80)
Dim g As Graphics = Graphics.FromImage(bmp)
Dim LinesPen As New Pen(Color.Black, 2)
LinesPen.Alignment = Drawing2D.PenAlignment.Center
g.DrawRectangle(LinesPen, 1, 1, 78, 78)
g.DrawLine(LinesPen, 27, 1, 27, 79)
g.DrawLine(LinesPen, 53, 1, 53, 79)
g.DrawLine(LinesPen, 1, 27, 79, 27)
g.DrawLine(LinesPen, 1, 53, 79, 53)
Try
'----------------ERROR HERE------------------
bmp.Save(Me.DestinationLabel.Text, System.Drawing.Imaging.ImageFormat.Png)
'-------^^^^-----ERROR HERE-------^^^^-------
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Please help if you can or if you have also experienced this.

Hi,
Most, if not all, errors inside GDI+ are reported as "generic problem occurred in GDI+".
If the affected line is an Image.Save chances are your path is incorrect or inaccessible,
your disk is full, or your destination file exists and is locked.
if you load an image from a file, most of the time the file remains locked as long as
the Image is alive. This would prevent you from saving an image to the same path.
It applies to Image.FromFile, and probably also to PictureBox.ImageLocation
The one exception I am aware of is when you use Image.FromStream
An alternative work-around is to work with a copy of the image:
load the image with Image.FromFile,
create a new image from it with new Bitmap(Image),
dispose of the original image.
|
|
|
|
|
I am not using FromFile. The image does not exist and is not overwriting another image. It is a completely new image which i have drawn the graphics from then added graphics objects (rectangles and lines) to, i still recive the same error. I just can't save it for some reason. I have no idea why. I have tried making a second image of the same size and making it equal the first one then saving the second one and i still have problems.
|
|
|
|
|
OK, some questions then:
1. is your path correct?
2. do all the (sub)directories exist?
3. is the path refering to an existing file?
4. if so, did that file get created very recently? explain!
|
|
|
|
|
Problem Solved, there was a slight error in the way i dealt with the filename.
|
|
|
|
|
If you load the image using FromFile, the file is locked for the entire liftime of the image object. This means you cannot save it back to the original file because of the lock.
Instead, use the FromStream method to load the image. When you close your FileStream object, the lock is released, then you can save the image back to the original file.

You're obviously right, but I recently found a case where if I used a stream, and then draw the image onto a new bitmap, it was drawn at 1/4 size. I don't know why this was happening, but it was a repeatable bug across many ( users ) machines.

That's whacked. I haven't seen it happen myself, ...yet. Hmmm. Any clues on the image format that it was using? TIFF, BMP, JPEG, all of the above? Dimensions, color depth, pixel format, compression?

They were JPEGs, they were a fair size, and they were 24 bit.

hi,
I am working with tab control in a MDI form. In one of my tab page, I’ve a split container control. Now I want to load another form in the panel2 of split container. Using “mytab_enter” event, I am loading all the controls of that Form into the panel container.
Dim objFrm1 As Form2
objFrm1 = New Form2()
objFrm1.TopLevel = False
SplitContainer2.Panel2.Controls.Add(objFrm1)
objFrm1.Show()
the form is getting loaded without any controls being displayed. A blank form.
In this the fact what I observed is. If I add controls to 1st tab page all the controls will get loaded without any problem. I face this problem with subsequent tabs.
Can any body please help me out in this problem?
Thank you,
Regards, Krishnaraj

AFAIK, there is no BackgroundImage property in the MsChart control. You'd have to either use a different control that exposes this functionality, or write your won.
