I was wondering if there is a way in VB6 to programmatically prevent a listbox from droping down?

I own a licensed copy of Visual Basic 6.0 and recently reloaded Windows XP and Visual Basic 6.0. I cannot use F1/Help - it gives message: "The MSDN collection does not exist." But Visual Basic 6.0 did not come with a MSDN CD/CDs. I had this capability before (Press F1, Help opens).
I know that MSDN is available online, but I need it on the road, local on my machine. I have searched long and hard for answers, but can't find how to re-install MSDN with my Visual Basic 6.0 package or anything online.
I'm sure I'm not the first one to have this problem. It might be useful to provide a solution on this site.
I am running Windows XP with SP2 updates. My Visual Basic 6.0 package includes one CD, plus Visual Studio 6.0 Service Pack 4 (I downloaded Service Pack 5). No MSDN CD.
When I run the setup.exe from the Visual Basic 6.0 CD, all the options I get are:
Microsoft Visual Basic 6.0
ActiveX
Data Access
Professional Features and Tools
Graphics
Tools
When I "Change Option" Microsoft Visual Basic 6.0, I get the following "sub"-options:
Microsoft Visual Basic Core Files
Package & Deployment Wizard
Wizards and Templates
WebClass Designer
Nothing about documentation. That won't happen, I suppose, unless I had a MSDN Libary CD, which the install asks for at the end of installing Visual Basic 6.0. But I know I never had a MSDN Library CD. How, then, did I have it working before? That is the current mystery.
I'll continue to be on the hunt for a solution.

"But Visual Basic 6.0 did not come with a MSDN CD/CDs" ???
Every version I have seen, Did come with the CD's
I don't know that this is of much help to you.
sorry,

You'r going to have to find that CD. The current versions of MSDN no longer integrate with Visual Studio 6, or any sub-version thereof.

Thanks, Dave and progload - I guess from two sources, I need that CD. I think I have a copy of Visual J++ from the Visual Studio 6.0 line - it's stored away in a trailer. Perhaps that box should include the MSDN CD with Visual Basic 6.0 Documentation?

MSDN isn't really published on a "per language" basis. It's, AFAIK, all of nothing.

I am trying to create an iframe server control that has a src that can be set in code behind, and also that checks to see if the client has changed the src and control will maintain the current src on postback. Here is my code:
Imports System
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.ComponentModel
Namespace IMCControl
<defaultproperty("src"), _
="" toolboxdata("<{0}:iframe="" runat="server">")> _
Public Class IMCIFrame
Inherits System.Web.UI.WebControls.WebControl
Implements INamingContainer
Implements IPostBackDataHandler
#Region " Windows Form Designer generated code "
'UserControl overrides dispose to clean up the component list.
'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer
'NOTE: The following procedure is required by the Windows Form Designer
'It can be modified using the Windows Form Designer.
'Do not modify it using the code editor.
<system.diagnostics.debuggerstepthrough()> Private Sub InitializeComponent()
components = New System.ComponentModel.Container
End Sub
#End Region
Private m_src As String = String.Empty
Public changed As EventHandler
Public Sub New()
MyBase.New(HtmlTextWriterTag.Iframe)
End Sub
<bindable(true), category("navigation"),="" defaultvalue("")=""> _
Public Property [src]() As String
Get
If Not viewstate("IFsrc") Is Nothing Then
m_src = viewstate("IFsrc")
End If
Return m_src
End Get
Set(ByVal Value As String)
viewstate("IFsrc") = Value
End Set
End Property
Protected Overrides Sub RenderContents(ByVal writer As System.Web.UI.HtmlTextWriter)
MyBase.RenderContents(writer)
End Sub
Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
If Me.src = String.Empty Then Exit Sub
MyBase.Render(writer)
End Sub
Protected Overrides Sub AddAttributesToRender(ByVal writer As System.Web.UI.HtmlTextWriter)
writer.AddAttribute(HtmlTextWriterAttribute.Src, src)
MyBase.AddAttributesToRender(writer)
End Sub
Public Overridable Sub RaisePostDataChangedEvent() Implements IPostBackDataHandler.RaisePostDataChangedEvent
OnChange(EventArgs.Empty)
End Sub
Public Overridable Function LoadPostData(ByVal postdata As String, ByVal collection As Collections.Specialized.NameValueCollection) As Boolean Implements IPostBackDataHandler.LoadPostData
Dim origval As String = src()
Dim postedval As String = collection(postdata)
If origval = String.Empty Or origval <> postedval Then
src = postedval
Return True
Else
Return False
End If
End Function
Sub OnChange(ByVal e As EventArgs)
If Not changed Is Nothing Then
changed(Me, e)
End If
End Sub
End Class
End Namespace
My problem is that the IPostBackDataHandler subs and functions don't fire. and the only src that the iframe remembers is the one initially set on code behind, and any subsequent changes to the src property made on the client (by javascript) are lost on postback. PLEASE HELP!!! Any and all comments are appreicated!

Here the code im using to print the word document but I need to know how to have it just open up for preview.
What do i need to change:
Function PrintDoc()
Dim WordObj As Object
Set WordObj = CreateObject("Word.Application")
WordObj.Documents.Open "C:\Wordtest.doc"
WordObj.PrintOut Background:=False
WordObj.Quit
Set WordObj = Nothing
End Function
Thanks For any Any Help
Nathan

WordObj.Documents.Open "C:\Wordtest.doc"
change to:
WordObj.Documents.Open "C:\Wordtest.doc",,Readonly
wordobj.printpreview will open it in print preview view (needs to be after the above line).
Also a small tip.
I know whan dealing with office automation you really need to use late binding because you can never really be sure what version of word the user will have, but it does help to use early binding when developing then change it later. With such a large object model as office has the intellisence really helps you a lot.

I tried that and all I got was a Runtime error that said PrintPreview is nat a method. Thanks for any more help. still kinda new to this whole VB thing thanks.
Nathan

|

What version of office have you got?
Try referenceing the word object library then either have a look in the object browser or use the intellisence. I am using office 2003 and it works fine.
Jonathan

Yea thats probably the problem then i Have office 2000.
Nathan

I have office 2000 at home. If nobody else has given you an answer i will try to have a look later (baby boy allowing).
|
|
|
|
|
Thank I think with your help I got closer its now WordObj.PrintPreview = 4 now if i could just get it to stay open. Thanks again.
Nathan

I know the the thing closing the word document is WordObj.Quit but if i remove this the document does not even try to open. So what do i need to change WordObj.Quit to equal. Thanks
Nathan

Make the word instance visible like this:
WordObj.visible=true

Hello i've got a problem with deleting a postion with deleting the current (or selected) member (view my member form in the project link below).
http://rapidshare.de/files/1970958/FP2_FilmStore.zip.html
I can add and view next or previous members but how do i delete the currently selected member????
Any ideas as im totally stuck and have no idea.

what are you talking about ? combobox ? listbox ? datagrid ?
does the control have an arraylist as datasource ?
ps:there is nothing comparable to what you talk about in the link you provided. is the link broken ?

For the link go to FREE at the bottom of the page, the next page (again at the bottom) you can download my uploaded app.
And the Members (control) are stored in arraylist. Although there is nothing in there to start with.
The user enters member details (and films) when the app is run.

You can use class ArrayList. It has a method RemoveAt(). Or if you prefer to stay with your current array then you can use Array.Copy to copy your array to another one then copy back. Array.Copy allows you to specify how many objects to copy, what positions to copy, etc; however, it seems like a bad solution. I prefer ArrayList but the downside of using ArrayList is that you have to cast from object to your class when you get an object from the array.

Can you give me an example of the array.copy as i'm a newbie also how would i know which one to delete??? If you can would you be able to give an example?
|
|

|

Here is the code using Array.Copy, although it's probably easier to create a loop and copy all elements in an array except the one you want to delete.
Dim str As String = "This is my original string"<br />
Dim originalArray() As String = str.Split(" ")<br />
'now to remove the fourth word: (index 3)<br />
Dim indexToRemove = 3<br />
Dim newArray(originalArray.Length - 2) As String<br />
Dim numElementsToCopyFirst = indexToRemove 'copy everything up to index right before the element to be removed<br />
Array.Copy(originalArray, 0, newArray, 0, numElementsToCopyFirst)<br />
Dim numElementsToCopySecond = originalArray.Length - indexToRemove - 1<br />
Array.Copy(originalArray, indexToRemove + 1, newArray, numElementsToCopyFirst, numElementsToCopySecond)<br />
'now replace original array<br />
ReDim originalArray(newArray.Length - 1)<br />
Array.Copy(newArray, originalArray, newArray.Length)
