Hi,
I am trying to create an vb app using winforms. I want to always have updated information in the app. So if there are more then one user, and one of users is adding a company, I want the other user to see the company as well after it has been added. Or when one user changes the status of a company I want this update to be send to the other users, if looking at the same data as well.
One of the obvious solutions would be to have a timer restrieving the data from the SQL db every couply of seconds, but I guess that will kill a network and there must be more elegant solution, pushing changed data forward. However all the docs I have read until now only talk about a single user and he or she pushing a button to update.
Can anybody give me some hints on where to go and some articles to read?
Thanks in advance

Depending on how much data is changed and how much data you have total you could do one of the following:
1. Give each table with data an extra column LastChange of type DateTime. If the column is indexed your clients can regulary ask for newly changed items.
2. Instead of marking ich item just make one field LastChange. Your clients poll this one and (if something changed) get all data.
3. Make some sort of server where your clients must log in. Let the server handle all data access to the db. This way the server gets to know all changes and can send any info he wants to all connected clients. Furthermore the clients wouldnt need to know the data layer - it would all be handled by your server.

I am making an FTP Class I've been able to login,get filelist,enter into passive mode. but when I try to download any file as small as 1 Byte it stops responding I'm issuing ("RETR " & Filename) command to FTP Server. If there is any problem correct me.
Do While True
m_bytBuffer.Clear(m_bytBuffer, 0, m_bytBuffer.Length)
m_intByte = m_objClientSocket.Receive(m_bytBuffer, m_bytBuffer.Length, 0)
m_strMes += ASCII.GetString(m_bytBuffer, 0, m_intByte)
If (m_intByte < m_bytBuffer.Length) Then
Exit Do
End If

Hi,
vb 6.0
I have a control with several events, and a container form listening for such events. the control also has some methods which are called by the container form to update a listview.
Everything was working fine until I decided to compile the project. when compiling the project I get the message: procedure not found -- even though intelisense allows me to select the procedure and I provide the correct number of arguments (4 args).
Does anybody have any experience with this type of behaviour, I'm in the process of creating the release version for testing and can't seem to go past the compile process.
Thanks....

Hi folks,
Solved my problem, I'm so deep in the forest that I can not see clearly...
anywho....
I had changed the function signature but did not bother to recompile the control project. Since the control project is in the same workspace as the form project calling it, I was making the wrong assumption that everything was getting compiled but the control project was not getting compiled therefore the diffrerence in method signatures....
duhhhhh.....

Hi,
I am trying to convert the code in this document: http://www.codeproject.com/cs/miscctrl/custommenu.asp[^] into VB.net instead of C#. I have got most of it done but I am missing the final step, or at least I hope it is the final step. In the article all the menuitems have the following two events added:
this.menuItem3.DrawItem += new System.Windows.Forms.DrawItemEventHandler(this.OnDrawItemSec);
this.menuItem3.MeasureItem += new System.Windows.Forms.MeasureItemEventHandler(this.OnMeasureItemSec);
When I look at the source article used for this article, the author writes about going to the eventtab on each menuitem. I am guessing this is typically C# as I cannot find it in VB.net. So can anyone please tell me how to do this?
Thanks

Your are looking for the AddHandler statement:

For your example:

AddHandler Me.menuItem3.DrawItem, AddressOf Me.OnDrawItemSec<br />

Could someone please help me on how to disable database login in crystal report 9.0?
Here's how I did:

then I wrote this code to call customer.rpt to make the report:
-------------------------------------------------------------------------
Private Sub CustomersPrintForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim CRYRpt As New Customers
Dim rst As MICControlLibrary.RecordSet = MICControlLibrary.DBContacts.DBSelectPrint(_contact_id)

Looking for some help please...
I can draw a 'Grid' on a form through OnPaint using Drawline methods -
I need to associate data from an array to this grid I draw and label. (I have no issues with working with arrays, not the question)
example: the grid I draw is a 10 x 10 labeled on the x/y axis appropriately 1 - 10. My data comming in is points associated with my grid (3,5) (2,7) etc.
So I would like to plot this.
However, the location on the FORM for where I have my grid set up as (1,1) for example, is actually (25, 75) (lets say) and these values will change as I resize the form -- But I still need to have my array data plotted on the (1,1) location I created in my grid.
Hehe..make sense what I am confused about?
How do I get my array data plotted & associated to the grid I create and not the underlying coordinates used by the Form itself that the grid is created on?
Appreciate any feedback.
I am including the code I have so far - it works nice as a basic grid creater I guess.
To change the dimensions, you change the "Space" variable.
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
'This is the declare of the graphics object
Dim g As Graphics = e.Graphics
'Size Variables
Dim gWidth As Integer = Me.ClientSize.Width
Dim gHeight As Integer = Me.ClientSize.Height
'Grid Spacing
'Will use a unit of 10 for the # plots to be used, defines grid spaceing
' will change to variable setting
Dim Space As Integer = 10 'this would be variable - # of plots defining size of graph
Dim xSpace As Integer = (gHeight - 10) / Space '-10 to allow 5 on top and bottom extra space
Dim ySpace As Integer = (gWidth - 10) / Space
'ADD LABELS
' will be written in with each line made
' x and y axis
Dim Label As String
Dim myFont As New Font("Tahoma", 10)
'Declare the Pen
Dim pPen As Pen = New Pen(Color.Maroon, 1)
'DRAW THE X HORIZONTAL LINES for grid
'Draw first line - bottom
'Draw a line x1, x2, y1, y2
g.DrawLine(pPen, 1, gHeight - 5, gWidth - 5, gHeight - 5)
'LABEL
Label = 1
g.DrawString(Label, myFont, Brushes.Blue, 1, (gHeight - 15))
'set up loop to draw remaining lines
Dim counter As Integer 'counter for loop
counter = Space - 1 '1st line has already been drawn
Dim n As Integer ' holder/count for loop
Dim x1Space As Integer = xSpace
For n = 1 To counter
'set up x1,x2,y1,y2 for next line to be drawn
g.DrawLine(pPen, 1, (gHeight - 5) - x1Space, gWidth - 5, (gHeight - 5) - x1Space)
'Label
Label = System.Convert.ToString(n + 1)
g.DrawString(Label, myFont, Brushes.Blue, 1, (gHeight - 15) - x1Space)
x1Space = x1Space + xSpace 'adds next space value to move line up
Next
'DRAW THE Y VERTICLE LINES for grid
'draw 1st line starting left -> right
'draw a line x1,x2,y1,y2
g.DrawLine(pPen, 5, 5, 5, (gHeight - 5))
Dim y1Space As Integer = ySpace 'need to use the ySpace now for spacing vertically
counter = Space - 1
For n = 1 To counter
g.DrawLine(pPen, (5 + y1Space), 5, (5 + y1Space), (gHeight - 5))
'Label
Label = System.Convert.ToString(n + 1)
g.DrawString(Label, myFont, Brushes.Blue, (5 + y1Space), (gHeight - 15))
y1Space = y1Space + ySpace
Next
End Sub
Protected Overrides Sub OnResize(ByVal e As System.EventArgs)
Me.Invalidate()
End Sub
End Class
SO its possible I am even approaching the whole problem incorrectly with what I have done above. The thought was to create the grid and then plot on it.. eventually the "Space" variable will be determined by first looking though the array for the min max values and constructing the grid and graph from there..
But first I need to figure out how to plot the !@%$#@! thing...
Thanks to all who took the time to read this.

I have the above code which sucessfully place data extracted from a Coma delimited text file in Column 1-8 of a ListView which have 12 ColumnHeader.
Problem:
How can i specify the column of the data to be display in?
E.g. Puting myObjectsFromFile.getObject(i + 1).Second in the 12th column instead of the 2nd, the myObjectsFromFile.getObject(i + 1).Third in the 9th column instead of 3rd .etc
Note: Juz a sample break down of what i need to do as my actuall requirement is slightly mroe complex

Is there any build-in function of Visual Basic .NET that lets me extract the dates from a GregorianCalender based on a given weeknumber of a given year?
For instance, extracting what dates belong to week 19(as an example) of a given year?

I'm using vb.net and I have 1 form with a webbrowser control on it, and one button on the form.
I have an html page I'm calling which has 2 radio buttons on it and a textbox.
I can fill in the textbox by going...
AxWebBrowser1.Document.Forms(0)("username").Value = "myusername"
My problem is, I'd like to select a radio button depending on its value...
How could I do that? I'd like to be able to select a radio button based on its value if at all possible....
I found a page on HTML Document Object Modeling here...http://www.w3schools.com/htmldom/dom_obj_radio.asp but cant quite get it figured out. 
Thanks for any help!

Heres My current code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
Dim Choice As String<br />

AxWebBrowser1.Document.forms(0).radiobutton.value(1) = checked<br />
ElseIf Choice = 2 Then<br />
AxWebBrowser1.Document.forms(0).radiobutton.value(2) = checked<br />
End If<br />
End Sub-------------------------------------------------------------
Here's the body of the page I'm using
<body> <br />

I am writing a routine which will display part of a jpeg image (say 3500x2000 pixels) in a PictureBox (size 1000x700 pixels) and then allow the user to scroll around the image by using the mouse (image scrolls whenever the right mouse button is pressed and the mouse is moved).
I am using Graphics.DrawImage to redraw the scrolled image.
gphpicbox.DrawImage(picturebox1.Image, New Rectangle(0,0, _
picturebox1.Width, _
picturebox1.Height), _
New Rectangle(intrelmoveX, intRelMoveY, _
picturebox1.Width, _
picturebox1.Height), graphicsunit.Pixel)
My problem is it is just so slow and not at all smooth.
Is there anything I can do to improve performance?
Thanks
NagaJim

From where does the gphpicbox object come from?
If you draw the image yourself I wouldn't use the picture box control (it is only useful when you let it paint the image itsself). Make your own Control (derive from control or userControl) and override the OnPaint method. Here you can do your drawings (the Graphics object can be retrieved from the eventargs). While the mouse is moving just set the appropriate properties and call YourControl.Invalidate(). That should do it.

Hello
I suspect that this is a simple error on my part but this example may help others starting out with ADO.NET.
I'm working on a very basic Database Application. I've included the full project as an attachment in this post.
Its a very basic Form that is the front end for a database containing contact information.
The form has many fields but I've only implemented the first 4 for simplicity.
The form has 4 buttons
1-Find = user enters record ID to bring up the contact information for that record (SQL Select used)
2-New = user can create a new record (SQL Insert used)
3-Save = user saves current record (updated or new- SQL Update or insert used)
4-Delete = Record deleted
I have used an access DB for simplicity but will need to use MySql or MS SQL for end project. Amen.mdb is included with project.
Parts That Work
1-Find Works OK
2-New Works OK until Save
Parts that Don't work
3 - Save - Insert only inserts the first 2 fields in the database! ie name & contact, phone & mobile don't get inserted! -
I don't understand this as the code seems OK
Update doesn't work at all - it causes an unhandled exception in the cmdUpdate part of my code.
The project was written in VS.NET 2003
Any Help greatly appreciated
