Hi,
Do you know any open source PDF libraries.
how to write in pdf using vb.net
|
|
|
|
|
the first link I provided is an open source way to create pdf's
for editing an existing one I havn't found any so far. I'v been looking for quite a while now since I could use it aswell but so far all the coude I'v found use the adobe library's and to be able to use them you need the full version
If I find a way I'll let you know but I'm afraid that for the moment I have to assume that it is not possible to do it without bying the full version of adobe (at least not legally possible)

Hi All,
I have one cheque printing module in my vb.net application. In that i am saving the x,y positions of different labels and setting label positions while previewing. Then I am printing the form as such. Since there is no form.print in vb.net, i am using the following code:
Private Print_Image As Image
'This is used to take the picture
Declare Auto Function BitBlt Lib "GDI32.DLL" ( _
ByVal hdcDest As IntPtr, _
ByVal nXDest As Integer, _
ByVal nYDest As Integer, _
ByVal nWidth As Integer, _
ByVal nHeight As Integer, _
ByVal hdcSrc As IntPtr, _
ByVal nXSrc As Integer, _
ByVal nYSrc As Integer, _
ByVal dwRop As Int32) As Boolean
Private Sub mnuPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuPrint.Click
'We make the form look pretty before its picture
Application.DoEvents()
Me.Refresh()
Application.DoEvents()
'Get a Graphics Object from the form
Dim FormG As Graphics = Me.CreateGraphics
FormG.SmoothingMode = Drawing2D.SmoothingMode.AntiAlias
'Create a bitmap from that graphics
Dim i As New Bitmap(Me.Width - 6, Me.Height, FormG)
'Create a Graphics object in memory from that bitmap
Dim memG As Graphics = Graphics.FromImage(i)
'get the IntPtr's of the graphics
Dim HDC1 As IntPtr = FormG.GetHdc
Dim HDC2 As IntPtr = memG.GetHdc
'get the picture
BitBlt(HDC2, 0, 0, Me.ClientRectangle.Width, Me.ClientRectangle.Height, HDC1, 0, 0, 13369376)
''Clone the bitmap so we can dispose this one
Me.Print_Image = i.Clone()
'Clean Up
FormG.ReleaseHdc(HDC1)
memG.ReleaseHdc(HDC2)
FormG.Dispose()
memG.Dispose()
i.Dispose()
'Show the PrintDialog
PrintDialog1 = New PrintDialog
PrintDialog1.Document = PrintDocument1
Dim r As DialogResult = PrintDialog1.ShowDialog
If r = DialogResult.OK Then
'Print the document
PrintDocument1.Print()
End If
End Sub
Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
e.Graphics.DrawImage(Me.Print_Image, 0, 0)
End Sub
All these are working fine.But now the problem is, all writings in the cheque are scattered and there is no clarity & smoothness. Anybody have any ideas to increase the clarity & smoothness? Or Is there any other ways to achive this?
Regards,
Hareesh

Hi,
One possible way is to simply loop through the rows of your dataset and add the values from the column you need:
<br />
Dim rw as DataRow<br />
Dim Total as Decimal<br />
'First "save" any changes the user made before this bit of code is triggered<br />
Dataset.AcceptChanges()<br />
'Then loop through all rows in the dataset<br />
For Each rw In Dataset.tables("sourcetable").Rows<br />
'best to add some validation here:<br />
If IsError(Decimal.Parse(rw.Item("price"))) Then<br />
'someone wrote his name in the price field instead of a decimal<br />
'kick his ass<br />
Else<br />
'increase the value of variable Total<br />
Total += rw.Item("price")<br />
End If<br />
Next<br />
'and then for example:<br />
TxtTotal.Text = Total.ToString<br />
Hope this helps you,
Johan
My advice is free, and you may get what you paid for.

the following link will convert c# to vb.net (I use it alot and it works fine(somethimes some adjustments are needed dough)):
http://www.developerfusion.co.uk/utilities/convertcsharptovb.aspx[^]
for you'r code this is the output:
Public Class EmployeeCollection<br />
Inherits System.Collections.CollectionBase<br />
Public Default Property Item(ByVal index As Integer) As Employee<br />
Get<br />
Return DirectCast(List(index), Employee)<br />
End Get<br />
Set<br />
List(index) = value<br />
End Set<br />
End Property<br />
End Class
-- modified at 7:26 Tuesday 17th July, 2007
just noticed the code above will not compile
this will and I think it will work too (hope so  )
Inherits System.Collections.CollectionBase<br />
<br />
Public Property employee(ByVal index As Integer)<br />
Get<br />
Return MyBase.List(index)<br />
End Get<br />
Set(ByVal value)<br />
MyBase.List(index) = value<br />
End Set<br />
End Property

Too much broken English. Rather I would say

Is what you are after a way of setting / getting the clipbard data in your code? If so then
clipboard.SetText("myString")
to add the selected text to the clipboard. Reading is a little more complicated since you might have something which is not text in the clipboard so you can...
Dim clipboardData as iDataObject = Clipboard.GetDataObject
if clipBoardData.GetDataPresent(DataFormats.Text) Then
Return clipBoardData.GetData(DataFormats.Text)
else
'The clipboard contains something other than text
end if

If you're using a rich text box you might also want to check if the data isn't an image since a rich text box accepts images too (altough at the moment I can't seem to get the images to display but it did it in an other program so it is possible and he'll always paste them (no errors))
however if you allow images formatting your text becomes a lot more difficult (you have to check if the selected text doesn't contain an image otherwise you'll get an error (image can't be bold or something else))

Hi
I have 1000 rows are there in our database,it takes long time for bind data to treelistview using datareader.
can u give me any solution plz
Regrds,
Ravi

Does the user really need all 1000 of those nodes? The ONLY solution you have to to not populate the tree with something the user isn't going to need.

I'm going to use my psychic powser and guess your using Sql Server 2005 Express? You might want to be a bit more detailed if you expect decent help :P
If you do have Sql Server 2005 Express then read this:
http://www.datamasker.com/SSE2005_NetworkCfg.htm[^]
If your not then be more detailed. Tell us what version of Sql Server, give us the exact error message and any error codes.

By "they" I presume you mean your employer. As for what format, many companies will have a set of templates for such things. Follow the format of the template.
