Dim ress As [Assembly] = [Assembly].GetExecutingAssembly
Dim strimg As Bitmap = CType(Bitmap.FromStream(ress.GetManifestResourceStream("statuses.bmp")), Bitmap)
ImageList1.Images.AddStrip(strimg)
I have added image statues.bmp to resource already, but it still error like that "Value of null is not valid stream"
So, how can i do?

You need to work out GetManifestResourceStream. It actually scopes your folder structure I believe, so if it's in a folder called Bitmaps, it's going to be Bitmaps.statuses.bmp, and perhaps even has your root namespace at it's head.

hi
i am using data grid and i want to update it when user change i but the fallowing command in button to save update but it did not work and it give error massage

<br />
the error messge (Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.)
|
|
|
|
|
Hello,
This error comes up when the Select statement does not return any Primary key column.
The SelectCommand must return at least one primary key or unique column. If none are present, an
InvalidOperation exception is generated, and the commands are not generated.
For more details on this, you may refer to the given MSDN Link:
http://msdn.microsoft.com/en-us/library/tf579hcz.aspx[^]
I hope this helps.

This doesn't seem like it should be hard but all I get is a blank form. Is there an error in my syntax? I checked, the file does exist at that location and it does contain text.
Imports System
Imports System.IO
Imports System.Text
Public Class Form3
Public Class Test
Public Shared Sub Main()
Dim path As String = "c:\temp\mytest.txt"
If File.Exists(path) = False Then
' Create a file to write to.
Dim sw As StreamWriter = File.CreateText(path)
sw.WriteLine("Hello")
sw.WriteLine("And")
sw.WriteLine("Welcome")
sw.Flush()
sw.Close()
End If
' Open the file to read from.
Dim sr As StreamReader = File.OpenText(path)
Do While sr.Peek() >= 0
Console.WriteLine(sr.ReadLine())
Loop
sr.Close()
End Sub
End Class
End Class
-Live long and prosper

Hello,
I have checked the working of the code and everything seems to be working.
I get a file created with text in it and also get the strings written in OutPut Window.
However, I am not sure what exactly you are looking for. If I am assuming correctly, are you
looking to write the text on the form or what. Can you explain the things in detail?

Allen

Add a label to your form. Then do this
label.Text = File.ReadAllText(path)

I can see nothing wrong with your code but then again I am a C# developer not a VBer (anymore). However the one thing I will point out is to dispose of your streams. In C# there's a nice using statement but in VB I presume you'll have to do something like the following:
Dim sr As StreamReader = File.OpenText(path)
Do While sr.Peek() <> -1
Console.WriteLine(sr.ReadLine())
Loop
sr.Close()
sr.Dispose()
I doubt it. If it isn't intuitive then we need to fix it. - Chris Maunder

hi
is their is away to check the first three letter from string
|
|
|
|
|
Hello,
You can use the Substring() method to implement the same.
For example:
<br />
<br />
Dim str As String = "Test String"<br />
MsgBox("First Three letters: " & str.Substring(0, 3))<br />
<br />
I hope this will help.

Load the XML into the XmlDocument class. This impliments the standard W3C DOM for accessing XML. Then you can do something like
doc.SelectNodes("/Gateway/URL")
to get a collection of the URL nodes, which you can then iterate over and examine. The language used to selecte nodes is called XPath.

Communication between multiple instances of a program with Shared members and events.
This works fine as long the instances are started by the same thread.
If I start multiple instances by clicking the exe file it doesn’t work.
What to do?

You need to create cross process communication, probably using WCF.

Thanks mr Graus,
I have to stay with .NET 2.0 and for WCF it seems that 3.0 is needed
What other options are there?

Hi all,
i want to convert RTF to PDF programmatically.
i had tried itextsharp also , but i am not able to figure out what to do
is there any one experience in this area
thanks in advance
|
|
|
|

If you're planning on writing your own component then you'd probably need to look at the RTF Specification, figure out how to read it and then map these different things onto the iTextSharp interface. It's a fairly obtuse interface I know (I've worked with it) but the biggest issue I see here is parsing the RTF.
I doubt it. If it isn't intuitive then we need to fix it. - Chris Maunder

hi,
i m assuming you are asking about datagridview. In vb.net 2005 following statement works
Dim Str As String = "YourValue"<br />
DataGridView1.Rows(DataGridView1.Rows.Count - 2).HeaderCell.Value = Str
hope this also works in vb.net 2003
