1. Look at the System.Data namespace for connecting to your DB and running SQL against it
2. I doubt you can do it, you need a button that says 'print view' which renders what you want to print in a new window.
3. The web is full of info on how to create a login page using the built in features of ASP.NET.

You need to look up references before asking, because otherwise you'll never learn how to work stuff out for yourself.
If you have a TextBox, called tb, then tb.Text = "This is the Text" will assign a value to a TextBox.

Thanx Chris for your valuable sugesstion of how to assign value to textbox but the question here was to get only one record from a list of records in database. ne ways i solved the problem. i think you are right that everyone should learn on their own.
Thanks and Regards

Hi Manik. I didn't mean that you shouldn't ask for help, just try to solve the problem yourself first. And perhaps explain it better, I read your second to last response as meaning you didn't know how to set a string to a textbox, and because that's such a basic question, I answered it AND said that for questions like that, you really shouldn't need help.
But, by all means, ask for help when you're stuck, that's what this forum is for.

Hi, i am a beginner in Software programming.
Q1) Can anyone tell me how to design a TCP/IP networking which the Server only listen to a specific CLient...
Let say.
Both Client and Server are using Port 8080.
A client been fixed with an IP ("192.168.0.2").
The Server will only wait(listen) to the CLient with IP("192.168.0.2")only.
My design is as following, but always give error "SocketException", Can anyone help me to correct it.
Dim connection As Socket
Dim socketStream As NetworkStream
Dim writer As BinaryWriter
Dim listener As TcpListener
Dim ipAddress As IPAddress = Dns.Resolve("192.168.0.2").AddressList(0)
' wait for request, then establish connection
Try
listener = New TcpListener(ipAddress, 8080)
listener.Start()
' accept an incoming connection
connection = listener.AcceptSocket()
' create NetworkStream object associated with socket
socketStream = New NetworkStream(connection)
' create objects for reading
writer = New BinaryWriter(socketStream)
' inform client that connection was successfull
writer.Write("SERVER>>> Connection successful")
Catch abc As SocketException
txtDisplay.Text = abc.ToString()
End Try
Q2) How can i display the CLient's IP address in Server side if sucessfully connected. Pls provide example code...
Thanks a million. Cheers.

Ok, I know what you are thinking.  Why was this posted on the VB.Net forum? Well, let me explain.
I Have a DHTML text editor that I currently import Microsoft Word documents into via IE. The only problem is only text comes across currently. I came across info on MSDN that said images can be saved out of Word 2003 as bmp files. So far I can open the document, get a handle on each image, and copy them to the clipboard, but for some odd reason, probably my fault  , I can't seem to save them to the hard drive.
I've included the code below, perhaps you can assist, especially if you know MS VB.NET and VBScript better than I, which wouldn't be difficult to do.  Basically I get the image copied to the clipboard fine but then I don't seem to be saving anything out. Nothing fails, it just doesn't save. Any help would be greatly appreciated.
Sub ImportWordDoc()
On Error Resume Next
Set wApp = CreateObject("Word.Application")
wApp.Activate
wApp.WindowState=0
call wApp.Resize(400, 400)
Set wDoc = wApp.Documents.Open(document.all.FileToOpen.value)
wApp.Visible = true
For index = 1 To wDoc.InlineShapes.Count
inlineShape = ""
Set inlineShape = wApp.ActiveDocument.InlineShapes(index)
inlineShape.Select()
wApp.Selection.CopyAsPicture()
data = ""
Set data = Clipboard.GetDataObject()
If data.GetDataPresent( GetType( System.Drawing.Bitmap )) Then
bmp = ""
bmp = CType(data.GetData(GetType(System.Drawing.Image)), Bitmap)
bmp.Save( "C:\mybitmap" + cstr(index) + ".bmp" )
End If
Next
Call wDoc.Close(True)
call wApp.Quit(True)
End Sub

I have made an Excel Addin that creates four buttons and links them to my forms to retrieve data. I used a Shared Addin project so that I would get a .msi file generated for me when I built the solution. All is well until I attempt to remove the addin. The msi file as put an entry into the Add/Remove Programs list so I simply went there and clicked remove. I went back to Excel and the buttons were still there. I have restarted the machine and the buttons continue to exist and connect to the forms that should have also gone away.
Any suggestions on how to get rid of it?
As a side point that may be of some concequence, when I reinstalled the program I ended up with 6 buttons coming up. All of these buttons link to the appropriate form. I believe this problem is related to the following code from my connect.vb file.
This only creates one button:
MyCJ = oStandardBar.Controls.Item("CJ")
If MyCJ Is Nothing Then
MyCJ = oStandardBar.Controls.Add(1)
With MyCJ
.Caption = "CJ"
.Style = MsoButtonStyle.msoButtonCaption
.Tag = "CJ"
.OnAction = "!<SEOEXCELADDIN.Connect>"
.Visible = True
End With
End If
This buttons gets duplicated:
MyTD = oStandardBar.Controls.Item("TD")
If MyTD Is Nothing Then
MyTD = oStandardBar.Controls.Add(1)
With MyTD
.Caption = "TopDrivers"
.Style = MsoButtonStyle.msoButtonCaption
.Tag = "TD"
.OnAction = "!<SEOEXCELADDIN.Connect>"
.Visible = True
End With
End If

hey,
Here is a wierd problem I've been breaking my head over for the last couple of days........ I am writing a program in VC which reads information off a window written in VB using the windows handles which I obtain programatically (and which can be viewed by Spy++). The object that I want to read stuff from contains 4 other objects
1. A drop down
2. Label (which I want to read)
3. A Tree
4. Some gif
Through Spy++ when I view this object within the VB application it shows it as "ThunderRT6UserControlDC" ( which is a VB thing ). However I cannot view 1 and 2 through Spy ++ while I can view 3 and 4....now I know that 1 and 2 are a part of the "ThunderRT6UserControlDC" cause I can hide the parent and all 1,2,3 and 4 disappear. If I can get the handle to 2 I can read in the text
Someone PLZZZZZZZZZZZZZZ help me with this its killing me.
To show it disgramatically -->
"ThunderRT6UserControlDC"
------------------------------
+ 2 +
+ 1 4 +
+ 3 +
+ +
------------------------------

sorry that diagram got screwed up the '+' forms the right side of the form user control

Hello All,
Can someone point me to a way to have either
A. A multiselect combobox for a property or
B. A collection that shows the items already filled in when elipses is clicked
I know that if I define a custom property as a collection it will show in the property browser as as Item... and when I click the elipses it will pop me into the window to Add/Delete items. What I need is a way to already have the items be displayed when the window opens up and to allow the user to Select/Deselect only items already present.
Ideally, I would like to do the old move from the list on the left to the selected list on the right. Alternatively, a multiselect combobox would also work.
I have used TypeConverters a little bit and have created a combobox which allows the user to select one item out of the combobox but I have never attempted what I am referring to above.
Thanks in advance to any ideas, suggestions, links or working code !
Have a great day!

Has anyone heard of a solution being too large to compile and run the application from the VS Development Environment. Like trying to debug an app.
Thanks

Friends;
I need your advise to decide if I should use VB6 or VB.NET in my next project that will deliver to customers. To me the hasle of asking customers to install .NET machine is too much, one of the problem is it will require 1G for .NET framwork.
Another thing is I heard alot about .NET but I don't see may real application using it so I don't know what is the catch. I am the type of programmer like to get the job fast to meet time to market and not "do what Bill tell you.."
I need your advise,
Thanks

Where on earth did you see that???? The redistributable for the Framework requires 150MB of hard disk space and a recommended minimum of 96MB of RAM.
The SDK version requires about 880MB of hard disk space and 128MB of RAM.
In my opinion, drop VB6. Development using the .NET Framework is MUCH easier. Lots of the functionality you'll need is included in the Base Class Library of the Framework, where-as in VB6, you have to write a bunch of it yourself.
Microsoft is also dropping support for VB6 soon.
The choice is up to you...

I agree with Dave. The redistributable file for .NET is only about 23M in size.
As for real world applications that use .NET, there is Vault[^] from SourceGear that was written entirely in .NET. I have worked on projects at Kodak and Xerox that use .NET and will be sold soon. And at Xerox it was .NET 2.0 that we used. I am also starting to use it for my own development and software that I sell. There are also alot of component development houses that create .NET version of their COM components. So there is alot of use in companies today, but you might not be seeing it.

I agree to above 2 comments.
Learning .Net also won't be much difficult, as you are already into VB6. Rather its having more on OO concepts, which will make ur work more easy. Maintenance, deployment etc also becomes easy to implement.
Once you start working on .Net you will feel like migrating ur existing vb6 app to .net.
Go ahead chap, find a good book on .Net and other resources start on with it.

In VB.Net, is there a simple way of adding another line onto an array. If not what is the best way?
|
|
|
|
|
If adding another lines means adding another index to the array, then you can use a simple Redim Preserve ArrayName(NumberofIndexes). If your array had one element then NumberOfIndexes should equal 2. Don't know if this helps you much
|
|
|
|
|
ReDim Preserve for arrays, but you might want to look at ArrayList or StringCollection (or many other .NET collections).
The collections offer good performance when adding new items (better than ReDim Preserve), but have other aspects that may reduce performance, so try ArrayList, and if your items are always strings, try StringCollection.
Also, if you have to do lookups by key on the list then Hashtable is great.
