You need to execute your sort routine in its own thread.
Have a look in the MSDN documentation about the thread class - there's examples there

Just review ur application architecture, it's possible u were using unecessary arrays to process something that might be in otherway could be handled by the fewer one.

Hi
I have made my DataGrid move to the next cell on TAB and Enter (the code
below) and it works fine, but when standing in the first cell on the new row (last row)
and pressing TAB or Enter the cursor moves to the second cell on the
PREVIOUS row and not the new row. Why? And if I MOUSE_CLICK in the first
cell on the new row, I can press TAB and it works fine. Is there a way I can
make pressing the TAB to the new row work like Mouse_Clicking the new row??
Protected Overrides Function ProcessCmdKey(ByRef msg As
System.Windows.Forms.Message, ByVal Keys As System.Windows.Forms.Keys) As
Boolean
If (msg.WParam.ToInt32() = CType(Keys.KeyCode.Enter, Integer)) Then
Keys.Send("{Tab}")
Return True
End If
Return MyBase.ProcessCmdKey(msg, Keys)
End Function
Please HELP!!!

Hi
I am devoloping an windows application. In the main window user can see different images. When the user clicks on the "send Mail" button the active image needs to send as email to the user. But it is not send straight away, the image is attached to the email and it should be shown in the default email client waiting for user to enter the email id. I had implemented it with MSMAPI but we need this in dotnetway. (64bit because MSMAPI is 32 bit.) I tried using the following
Dim emailMessage As New System.Text.StringBuilder
emailMessage.Append("mailto:kalyan.v@yahoo.com")
emailMessage.Append("&subject=this is test subject")
emailMessage.Append("&body=this is test body")
emailMessage.Append("&Attach=c:\\a.txt")
Dim myProcess As New Process
myProcess.StartInfo.FileName = emailMessage.ToString()
myProcess.StartInfo.UseShellExecute = True
myProcess.StartInfo.RedirectStandardOutput = False
myProcess.Start()
myProcess.Dispose()
but i was not able to attach the image to this email message. but i can see the outlook client with body and subject.
Please help me out in this issue as soon as possible

Hi All,
I am using access database and vb 6.0 in my application.
I want to store image/excel file for this purpose i decide to use OLE object datatype of access.But could not get sample code for my purpose.
If anyone know any link please pass to me.
Thanks,
Nagraj

It's been a long time since i stop using my vb6.
Now i'm using vb2005.
You can store many kind of file into your OLE object field.
THe concept is:
First, you need to read all bytes of your file and put it into an array of bytes.
Last, then you can store this array into your OLE Object. Simple isn't it?
In VB2005 you can do this with a line of code:
--------------------------------------------------------------
Imports System
Import System.IO
Class Streamer
'It will return array of bytes.
Public Function GetByteArrayFromFile(ByVal FileName As String) As Byte()
Return File.ReadAllBytes(FileName)
End Function
'It will make the file form array of bytes.
Public Sub MakeFileFormByteArray(ByVal FileName As String, ByVal ByteStream As Byte())
File.WriteAllBytes(FileName, ByteStream)
End Sub
End Class
--------------------------------
You need to make the routine to retrieve and store the data by your own.
I believe you can do that.
If anyone can convert it to vb6? Plz Helo him
Thanks before

I can display my barcode in my crystal report successfully when i run at crystal report v by using code 128 font.
Unfurtunately, when i want to hook my crystal report in VB.NET form with CRViewer30.CRViewer. The barcode became a string of characters...
Isn't i need to define the code 128 font in my VB.NET form even the barcode can display properly in my crystal report..
Any idea about it?

I see no sign of that. where have you looked ? Did you try google ? Did you search this site ? There are plenty of other barcode articles here, although that was the first one I saw in VB, plenty are in C#.

Try Fontware. I have used them in the past for barcode solutions, including EAN128.

Hi,
I have to write a program that uses a webcam to capture an image of a barcode, then translate it to numbers then search these numbers in a database and update the time that the barcode is imaged.
I'm not a profesional programmer, I think of some ways, but I think all of them lacks something, my biggest problem is I can't find a way to capture & import the image from webcam to my program, can anyone please help me with a code or someway that I can do this task, & I think I saw a barcode translation code somewhere, can anyone please help me with it, tell me if there is any SDKs or codes that do this thing.
I'm totally out of ideas, so if someone can be so kind & give me any ideas I would be very thankful, I use VB.net for writing my code.
Thanks.

Only in the VB.NET forum....
There is an article on reading barcodes on CP, I thought, in C#. You can use DirectShow to get the video from the webcam, there are CP articles on this, also. Either way, I would not have thought a web cam was the ideal device for reading barcodes. Tell your boss to buy a barcode scanner, they deliver the barcode as a number to your code, and they don't cost that much.

That this is the forum to find questions that start with 'I'm not a programmer, but I need to *insert difficult task here*'. People seem to think that if they download VB Express, they can write anything, as if by magic.

Hi there,
I have a bit of a stupid question but I just dont know how to solve it, so here goes:
I am currently busy with an application that uses tree view to traverse between screens, and at the moment I have a form for each screen.
Only the panel part of the screen changes when the user navigates so I want to change my solution to refresh the panel with the appropriate one when the user navigates.
How would I go about doing this?
Thanks,
Igor.
