Installing VS - sql develop edition
I am installing VS 2008 pro,
First I uninstalled all express editions, and also sql express.
Then installing vs 2008 pro it installed sql express again.
Then inserting cd #2, for the SQL developer edition, it wants to update sql
express, but i notice with the service pack 2 that not all options are
available for the sql instance.
Should I have re-uninstalled sql express after vs2008 installed it again and
have just 1 clean developer edition on?
I am a bit confused.
In the mean time I will uninstall all sql instances and then try to
re-install from the cd from scratch.
Seeing that I can always re-install sql express if thats the way to go about
it.
Thanks,

O.T. copying 1TB from drive to drive in XP
I ask a lot of VB questions here but this isn't related to VB. I'm not
sure where to get help with this question but perhaps someone here would
know and not mind giving me some ideas.
We've got a Linux samba server currently storing very close to a
terabyte of 70kb to 956kb files. They are stored in a directory
structure by day. For instance files from August 1st 2007 are in a
directory s:\2007\08\01.
I need to copy all these file off this system and onto a 2TB windows
drive. The Linux server needs to be left in production during this
time. I'd like this to occur as fast as possible. I've tried
everything and nothing moves anything very fast. I've tried TeraCopy,
RoboCopy, SyncToy, and each was a real disappointment. I'm currently
running 6 command windows each running XCopy on a different set of
directories. For instance one command window runs this batch file:
xcopy r:\2007\01\*.* s:\2007\01 /D /E
xcopy r:\2007\02\*.* s:\2007\02 /D /E
xcopy r:\2007\03\*.* s:\2007\03 /D /E
another picks up with months 4, 5 and 6 etc.
It's important to remember that this process could get interrupted and
it would be terrible to have to overwrite files that were already copied
in order to make sure all of them got copied so I want something that'll
copy only files that don't already exist on the target drive -- hence
the /D on the xcopy.
According to Task Manager my pc is not taxed at all. Network trafficd
is at 2.5 % MAX -- ususally less than 1%. The CPU Usage is 0 to 2%.
This machine has 2GB ram. It's on a 100mb ethernet network with limited
traffic.
Any ideas would be appreciated. Tag: change value in data grid view Tag: 407287
Changeing screen origin from top-left to bottom-left
I'm playing around with a graphics project. I have a form that contains two
toolstrips. One at the top running the width of the form from left to right
and the other on the left running the entire height from top to bottom.
I managed to draw a filled rectangle that fills the entire area between the
toolstrips, but the drawing starts at the top left hand side of the form and
disappears behind the Start bar.
What I would like to do is Draw the rectangle at the bottom left hand side
of the screen and stop to the top right. I have a reference book titled,
"Visual Basic 2005 Programmers Reference." Inside this book on page 553 there
is a subroutine called MapRectangles that maps real word coorodinates to
device coordinates. This routine also allowed you to invert the direction of
the Y-axis.
My problem is: My real-world coordinates and device coordinates have to be
plotted in the same area. Can anyone tell me how to do this?
Thanks,

Print Forms from Visual Studio 2005
Hi,
We're creating a winform application, and I'd like to print out the actual
forms from within VS2005 without having to Build and run the code. Short of
making screenshots and cropping out the actual form, is there any freeware
or built-in tool to do this task?
Thanks --

Parallel Port IO under VB.net 2008 Express and Vista
I am working with the latest (as of March 2008) version of MS VB 2008
Express and I am looking for some code examples to write to the
parallel port. Basically turning pins off and on. I see many posts on
the subject but I havent come across anything talking about it with
Vista.
Has anyone had any experience with parallel port control under Vista?
If you have and have some good code or links can you please share
them?

Unable to edit a line of code while in break mode...
I have a vb.net 2005 project and wonder what else needs to be enabled to
allow me to edit a line(s) of code while in break mode and then bne able to
carry on with execution of the application. Currently, if I attempt to
change a line of code (either the line I am currently on, or any subsequent
lines) in break mode, I get a message at the bottom that indicates it is in
read only mode and that no changes can be made.
I have ensured that the "Edit and Continue" is enabled and that the JIT
debugger (found in Tools->Options->Debugging) is also enabled.
My co-worker using the exact same version of vb.net (same service pack and
all) can do what it is I want to be able to do. We have checked settings on
both machines and can't seem to find the right one. I'm hoping it's an easy
fix! :-)

help on downloading a text file from a website into memory
I have uploaded a text file to my website and can be accessed using a
browser i.e.
http://www.mysite.com/schedule.txt
The text file is just plain text on multiple lines ie
This is a test on line 1
--------------------------------
This is a test on line 3
++++++++++++++++
Line 5
What im trying to achieve is to have a button on my vb form brings up
a msgbox which in turn displays the contexts of the text file
(including the same formatting ie with carriage returns)
I've found sample code on the web which outputs a file to a text box
which i tried to amend but i found that I lost the carriage returns
or line breaks as these were replaced with spaces.
Can any one help me to change this code or is there another way to go
about it

ASP.NET GridView Control basic question
This is probably a stupid question, but I've never used the ASP.NET GridView
control before, so I hope you'll bear with me and give me a clue.
I've got a Gridview on my webform to show the contents of a database table.
It's configured to show both "edit" "delete" and "insert" options in the
commandfield.
That's all well and fine, the edit and delete options work as they're
supposed to, but I simply don't understand the insert row functionality.
First of all: When I start out, my table is empty. That means that instead
of rows, the EmptyDataText is show, and thus no "insert" button is shown in
the grid. How do I go about inserting the first row?
Second: When my table DOES contain data, all three options are shown, but
the Insert option doesn't do anything. Are there other properties I have to
set or other considerations I have to make than just set the CommandFields
ShowInsertButton property to true?
Cheers,

Passing a simple structure from VB6 to VB.Net Options
Hi
I have created a simple COM Class in VB.Net containing a simple
structure and function:
Public Structure MyStruct
Dim Param1 As Byte
End Structure
Public Function ShowStruct(ByRef MyPassedStruct As MyStruct)
' Do nothing
End Function
In VB6, I want to call the .Net function and pass the structure.
Public Type MyStruct
Param1 As Byte
End Type
Private Sub Command1_Click()
Dim netCall as New netDll
Dim testStruct as MyStruct
testStruct.Param1 = 10
Call netCall.ShowStruct(testStruct)
End Sub
When I try and comple my VB app it gives me an error saying 'ByRef
Argument Mismatch'. What am I doing wrong?
I have managed to pass integers and strings ok, I'm just having a
problem with structures.
Thanks

keybd_event again!
Hi all, I know I didn't get much response to my last question concerning
keybd_event, but someone out there must have an idea what is going on.
I've fixed a couple of the issues I had with the code I was using
previously, running a DoEvents in my char loop helped a great deal, also
supplying the key_up after the key_down helped a lot. However, I have one
problem I can't get round, and all the articles on the web don't describe
this problem.
The following table shows the problem:
Input Data Caps Status Result
"abcdefg" Off ""
"abcdefg" On ""
"ABCDEFG" Off
"abcdefg"
"ABCDEFG" On "ABCDEFG"
It get's even stranger when I start trying to send Shift characters such as
% or *. This is a data wedge application that is taking data from a PLC,
this data could consist of any ascii characters so I can't afford to loose
any.
I have also looked into SendInput, but this doesn't appear to exists in the
Compact Framework. PostKeybdMessage is apparently another way to achieve
what I want, but I can't find a single example.
One thing that is worrying me is the portable keyboard drivers, which are
mainly written by the manufacturer of the unit, will this application work
on some units and not others?
Is there a way I can bypass the keyboard call and send data directly to the
current application/control with focus?
Any information or suggestions at this point in time would be very much
appreciated.
Cheers. Tag: change value in data grid view Tag: 407229

Advanced and basic examples on how to write a DLL
Hi,
On the net, there are no much explanatory examples that tells how to
write a DLL using VB.NET. There are a few but completely lack of
teaching ones that isn't useful for me. Also i had some books but none
of them tells how to write a DLL step by step and deeply and i'd like
to know the priciples of class libraries rather than coding in a
regular exe.
So, i'd like to know what and how i should know writing DLL's
functions, properties (what get & set do and their arguments in dll),
interfaces,
The only clue about writing a DLL i had in that thread (Thanks Tom):
http://groups.google.com/group/microsoft.public.dotnet.languages.vb/browse_thread/thread/3b2498ad9e00674a/1973fd12aad4b765?hl=en&lnk=st&q=class+library#1973fd12aad4b765
But i want to extend and figure out what principles and techniques
must be applied further, any and more code samples are greatly
appreciated.
Thanks Tag: change value in data grid view Tag: 407217

Deleting multiuple rows from a database...
I am working on a new vb.net 2005 project using SQL server 2000 as the
backend db.
I have a listview where control I want a user to be able to select either
just one or multiple rows in the listview and perform an action on them. If
the user chooses to delete these rows I wonder what the best way to handle
the deletion of multiple rows is...
Right now I have a stored procedure for deleteing jsut opne row. i.e delete
from {tablename} where field1 = Parm1". However, if the user selects say 10
rows, should I loop through the lsitview items and call this SP each time,
OR can I somehow batch them so that I can run the stored procedure just
once - which would then delete all selected rows using a clause similiar to
the following.... "delete from {tablename} where field1 in (select field1
from{tempdeleteditemstable})"
Any ideas if this is the best way to do it - or is simply looping through
the listview and calling the stored proc to do a single row delete each time
ok? They would never be deleting that many items at once - but definately
there may be times when multiple deletes will be required...
Thanks, Brad Tag: change value in data grid view Tag: 407168
LINQ with SQL Server
I just read few notes on LINQ.
I am really very impressed the way it works and do queries from SQL Server.
I want to know is the LINQ only does the SELECT statment or does it also
handles UPDATES and DELETIONS.
I am very curious about this, so please provide me some knowledge.

Reporting options question
I have an app( vb .net 2.0) that I am about to get into the reporting
portion, the app has an access 2007 db, and have logo file stored in a
directory on the computer (to save space in the database). I want to be able
to show the logos at the top of the report. Depending on the options selected
I want to be able to color code the report (text, boxes and linesâ?¦).
IT seems that I have to reports to choose from, Crystal, vb built in
reporting, last was to make my own.
I need to be able to customize the report for color code print logos on the
report.
What do you all think on the options of doing:
Crystal report â?? doesnâ??t seem like I can dynamically change a picture
objection the report and I keep running into logon error.
Vb built in report â?? it doesnâ??t seem as easy to customize an in vb6, I canâ??t
seem to write any code and use my on connection string with data sets.
Building my own report â?? I am just wandering if it is work building your own
reports, making a form to show the data, then having to print or print
preview it.
I am kind of at a decision point and wanted to see what some of you thought
or have experience with some of the options? Tag: change value in data grid view Tag: 407150
Timeouts when getting picture from network camera
I am performing the following bass tasks to get an image from a network
camera:
Dim WebRequest As WebRequest
Dim newpic As Image
Command = "http://192.168.0.200/jpg/image.jpg"
WebRequest = System.Net.WebRequest.Create(Command)
WebRequest.Timeout = 5000
Dim webresponse As System.Net.WebResponse
webresponse = WebRequest.GetResponse()
Dim respStream As System.IO.Stream = webresponse.GetResponseStream()
newpic = Image.FromStream(respStream)
My problem is that occasionally it hangs on the last line when trying to get
the actual stream. Whilst you can specify a timeout for WebRequest, there is
no timeout for WebResponse or respStream. As a result the process hangs for
5 minutes (which seems to be the default timeout) Is there any way round
this? Should I be doing this a different way?

NotifyIcon Confusion
Hello,
I am a little confused over the behavior of a form with a NotifyIcon.
The property ShowInTasbar of the form is set to false. The NotifyIcon
does have an Icon set.
When I minimize the form, the Icon appears in the system tray as
expected. But, when I click on the icon the first time, the form
restores to a small window just above the Taskbar as if it had been
minimized.
A second mouse click on the Icon restores the form in its full glory.
The code below is complete. I created this simple test application
just to test the NotifyIcon behavior.
The behavior I would like is as follows.
1. Not visible in the Taskbar
2. Minimize hides the form.
3. An attempt to Close the form without password hides the form.
4. Click on the Icon restores the Form to previous location.
Public Class formTest
Private Sub formTest_FormClosing(ByVal sender As Object, ByVal e
As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
If TextBox1.Text = "PASS" Then
e.Cancel = False
Else
e.Cancel = True
Me.WindowState = FormWindowState.Minimized
End If
End Sub
Private Sub formTest_Load(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles MyBase.Load
NotifyIconX.Text = "Just_A_Icon :" & vbCr & "Double Click to
Activate."
End Sub
Private Sub formTest_Resize(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Resize
If Me.WindowState = FormWindowState.Minimized Then
Hide()
End If
If Me.WindowState = FormWindowState.Maximized Then
Debug.Print("Showing")
Me.WindowState = FormWindowState.Normal
Show()
End If

Cannot Reference Parent variables from a MDI Child Form
Hi everyone
Some help pls.
1. MDI Parent Form
Have a variable Public TestVariable As String = "AAA"
In the Load procedure TestVariable = "BBB"
2. MDI Child Form
Do a debug.print (TestVariable) and displays "AAA"
If I hold my cursor over TestVariable in the IDE it
displays "BBB"
I do not see how I can reference the current value in TestVariable of "BBB"
in my code
The real reason for this is that I am in 1 MDI child form and I want to
determine if another MDI Child form is active
I want to get the value MDIParentForm.MdiChildren.Length so I can
manipulate the forms to determine if the form I am concerned with is not open.
When I reference MDIParentForm.MdiChildren.Length from the MDI Child in the
coder it always shows 0 (Zero)
When I hold my cursor over MDIParentForm.MdiChildren.Length in the IDE it
displays 3 which is the correct number of MDI Child forms that are open.
Totally confusing
thanks

Long latency when creating a new FileStream...
Using VS2005, VB.NET,
I have a multi-threaded application. In one of my threads I need to
read a file as a binary stream. I am able to accomplish this using the
following code:
1 Dim BinaryFile As FileStream = New FileStream(<some file name>,
FileMode.Open, FileAccess.Read, FileShare.Read)
2 Dim BinRead As BinaryReader = Nothing
3 Me.BinRead = New BinaryReader(BinaryFile)
4 Me.BinRead.BaseStream.Seek(0, SeekOrigin.Begin)
5 Me.BinBytes = Me.BinRead.ReadBytes(<number of bytes to read>)
The code above works for me save one issue: on the first execution,
line 1 takes a really long time (4-7 seconds) to execute and don't
have any idea why.
Anyone have an idea what could be causing this latency and how to
avoid it?

anyone recommend a neat way of handling this without having to write an

Background Worker Cross Thread UI problem
I am using the BackgroundWorker in VB2005.
I understand the problems of updating a form from a thread, and this can
normally be overcome by doing the updating on the ProgressChanged Event. As
I understand it, this event will operate on the thread that invoked the
original RunWorkerAsync (which may not be the UI thread).
I have a thread, which calls another thread and it is in this thread that I
need to update the form. I have read much about call backs and delegates but
this seems to refer to life before the BackGroundWorker was introduced (whch
I thought did away with all this).
What is the best way for me to update the form in the above circumstances?

Generate and send outlook appointments/meeting requests
Hi Guys,
I have a vb.net ASP.NET based application, the want the user to have an
option to send himself a reminder via the application.
All seems good butqhen the mail is received bythe outlook user, it is not in
a proper request format and the user does not have the option to "accept"
etc..
What he gets is a simple text message as below:
Start: 3/10/2008 22:58:00
End: 3/10/2008 22:58:00
Location: Phone/Email
Details:
CUSTOMER: - ()
---------------------------------------------------------------
does this work? at all?
let's see....
PHONE: MOBILE:
EMAIL:
I have all the properties for the reminder and the following code:
Public Sub SendOutlookAppointment()
Try
Dim oApp As Outlook.Application = New Outlook.Application
' Create a new AppointmentItem.
Dim oAppt As Outlook.AppointmentItem =
oApp.CreateItem(Outlook.OlItemType.olAppointmentItem)
'oAppt.Display(true) 'Modal
' Set some common properties.
oAppt.Subject = "Subject...."
oAppt.Body = "CUSTOMER: " & CurrentCust.cust_id & " - " &
CurrentCust.cust_fname & " " & CurrentCust.cust_lname & " (" &
CurrentCust.cust_company & ")"
oAppt.Location = "Phone/Email"
oAppt.Start = Convert.ToDateTime(calRemind.SelectedDate)
oAppt.End = Convert.ToDateTime(calRemind.SelectedDate)
oAppt.ReminderSet = True
oAppt.ReminderMinutesBeforeStart = 15
oAppt.BusyStatus = Outlook.OlBusyStatus.olBusy ' olBusy
oAppt.IsOnlineMeeting = False
' Display.
'oAppt.Display(true)
'get rep info
Dim rRep As Rep = RepDB.GetRep(ddlRepRemind.SelectedItem.Value)
'create the mail message
Dim mail As New Mail.MailMessage()
'set the addresses
mail.From = New Mail.MailAddress("Reminders@solarpathusa.com")
mail.To.Add(rRep.rep_email)
'MsgBox(oAppt.Subject.ToString)
'mail.Subject = oAppt.Subject.ToString
mail.Body = "Start: " & oAppt.Start & vbCrLf & _
"End: " & oAppt.End & vbCrLf & _
"Location: " & oAppt.Location & vbCrLf & _
"Details: " & vbCrLf & oAppt.Body & ControlChars.Lf &
"MSPBot Ver. " & sVer
'send the message
Dim smtp As New Mail.SmtpClient(sSMTPServer)
smtp.Credentials = New System.Net.NetworkCredential(sSMTPUser,
sSMTPPass)
smtp.Send(mail)
oAppt = Nothing
Catch ex As Exception
ErrorLogger.HandleEx(ex)
End Try
End Sub
I want to use regular sendmail to send the reminder since I may not have
outlook on the server the application is running on.
Any ideas?
Thanks! Tag: change value in data grid view Tag: 407094
Set Output window as default?
When ever I run a project the windows that open at the bottom always default
to autos and command window... I REALLY want the default to be autos and
output, is there anyway to set it like this? It use to be like that in past
versions.. but in recent versions it's defaultint to command... and it I set
it to output before i run the project it switches right back to command...
and is annoying as heck... how can I change the default window that shows?
Thanks! I have VS2008 now but this happened since VS2005... VS2003 didn't do
this for me.... Tag: change value in data grid view Tag: 407081
Post-build event
I have a solution that contains a bunch of VB.Net 2005 projects. After I build
the solution I want to run a batch file if any of the projects created new
output files. I know how to set up an individual project to execute a
post-build event if the project created new output files, but how do I do the
same thing at the solution level, taking into account whether or not *any* of
the projects created new output files?

the return of VB?
hey I just wanted to send a quick shout out-- I saw in the MSDN
magazine the other day.. that said that VB Is more popular than C#.. I
wanted to see if anyone had more information about this?
I also had to say a quick thanks to everyone; VB 2008 _ROCKS_ compared
to VB 2005.. And the VB family is again finally competitive with MS
Access in developing small quick apps. Just had to say thanks to the
whole team for helping to get this done!

where is the real VB group?
hey I went to Microsoft.Public.VB today and google says
You cannot post messages because this group is only available as an
archive.
I'd like to know where the real VB newsgroup is?
I surely don't really write VB.net for the most of the stuff i do.. I
do use Vb 2005 for some things and Vb 2008 for some things..
But I mainly write VB in Outlook, Access, Excel, Word and Visio.. I
just don't know where I can go to ask questions.
Thanks

ICollection(Of T) interface - Contains() method
Hi. I have the class below that implements the ICollection(Of Object). My
problem is that I can't seem to build an efficient Contains() method. My
Contins() method logic requires an exception in order to identify that an
item doesn't exist. Is there a better way to program this so I don't have to
catch an exception? Thanks.
Public MustInherit Class AbstractCol
Implements ICollection(Of Object)
Protected _Collection as Collection
Public Function Contains(ByVal item as Object) Boolean Implements
System.Collection.Generic.ICollection(Of Object).Contains
Try
If Not _Col.Items(item) Is Nothing Then Return True
' you would think the above Is Nothing check would prevent an
exception but it doesn't
Catch
' This happens if the item doesn't exist.
Return False
End Try
End Sub
End Class Tag: change value in data grid view Tag: 407062
Deserialize Soap Formatted object from string
I serialized an object perfectly fine to SOAP and have it stored in a
database as a string (sql server 2005 in a XML data type field) now I am
pulling that value back and want to de-serialize it using the soap
formatter's deserialize method... but it takes a stream.. .what is the best
way to take this value and deserialize it back? How do I create the stream
to deserialize it? I have it as a text string in the program right now
holding the SOAP XML. Thanks! Tag: change value in data grid view Tag: 407051
RichTextBox.RTF not updating properly? Please help!!
Hello,
I have a little form that people can fill out to generate CD labels
from an RTF template. The template basically contains variables that
are replaced by the text typed into the form.
I also have a "Preview" tab which will show a RichTextBoxcontaining
the output of the label generator (ie. the template, with the
variables replaced).
I am able to load the template into a RichTextBox without problems.
This gives me a RichTextBox containing a CD label with words like
%MIDDLE-LEFT% and the other variables.
Then I have the code below, which replaces the text with whatever is
in the user-edited textboxes (eg. txtMiddleLeft.Text):
[code]
txt_Preview.Rtf = templateRTFText // this works fine
tmpVar = Replace(templateRTFText, "%MIDDLE-LEFT%",
txtMiddleLeft.Text, , , CompareMethod.Text) // this works fine
txt_Preview.Rtf = "" // this works fine!
txt_Preview.Rtf = tmpVar // this does not work!
[/code]
This does not work. The variable tmpVar ends up with the correct,
updated data (I checked by copying it to the clipboard and pasting it
into a new RTF file- the variables were replaced). But the
RichTextBox still contains the template text. If I copy
txt_Preview.Rtf to the clipboard, it still contains the template data.
No errors are generated when I run the last line. Can someone please
help me! How should I be accomplishing this?
Note that I am not using PrintPreviewDialog because I need this to
appear inside an existing tab, and I also have not been able to get
PrintPreviewDialog to work properly (I have limited time for this
project).
Thank you. Tag: change value in data grid view Tag: 407050
