I am developing a mediaplayer by customising Windows Mediaplayer Control. The mediaplayer should have the ability to detect whether there is already an audio playback running on the Windows 98/2000. If there is one running, the mediaplayer should stop it and start to run its own.
I know there is a property in Mediaplayer control which is called AudioStream, the value of which has been set to -1 be default. But I don't know how to make use of it.
Any help are greatly appreciated.

Hi
I'm creating new menu and toolbar in AutoExec sub, and removing it in AutoExit. When AutoExit executes I can see that menu and toolbar dissapear, but when I delete .dot from autostart directory and launch Word they are back. But when I manually execute AutoExit then menu and toolbar dissapear forever (strange, isn't it). Here are my subs:
Sub AutoExec()
Dim PKICommandBar As CommandBar
Dim PKIMenu As CommandBarPopup
Dim ETSIMenu As CommandBarPopup
Dim lTest As Long
'menu
Set PKIMenu = Application.CommandBars("Menu Bar").FindControl _
(Type:=msoControlPopup, Tag:=sMenuName)
On Error Resume Next
lTest = PKIMenu.Height
If (lTest = 0) Then Set PKIMenu = Application.CommandBars("Menu Bar"). _
Controls.Add(Type:=msoControlPopup)
PKIMenu.Caption = sMenuName
PKIMenu.Tag = sMenuName
On Error Resume Next
PKIMenu.Controls(sETSIMenuName).Delete
Set ETSIMenu = PKIMenu.Controls.Add(Type:=msoControlPopup)
ETSIMenu.Caption = sETSIMenuName
With ETSIMenu.Controls.Add(msoControlButton)
.OnAction = "SignDocument"
.Caption = "Podpisz dokument"
End With
With ETSIMenu.Controls.Add(msoControlButton)
.OnAction = "Settings"
.Caption = "Ustawienia"
End With
'toolbar
On Error Resume Next
Application.CommandBars(sETSIMenuName).Delete
lTest = 0
Set PKICommandBar = Application.CommandBars.Add
PKICommandBar.Name = sETSIMenuName
With PKICommandBar.Controls.Add(msoControlButton)
.Style = msoButtonIconAndCaption
.FaceId = 22
.TooltipText = "Podpisz dokument"
.OnAction = "SignDocument"
End With
With PKICommandBar.Controls.Add(msoControlButton)
.Style = msoButtonIconAndCaption
.FaceId = 22
.TooltipText = "Ustawienia"
.OnAction = "Settings"
End With
PKICommandBar.Position = msoBarTop
PKICommandBar.Visible = True
End Sub
Sub AutoExit()
On Error Resume Next
Application.CommandBars(sETSIMenuName).Delete
On Error Resume Next
Application.CommandBars("Menu Bar").Controls(sMenuName).Delete
MsgBox ("exit")'that's why I can see that menu and toolbar dissapear when I close Word
End Sub
Thanks for any help

Hi
I've created a toolbar in Office 97, but I don't know how to change the icon (I don't want to use standard icons). I would like to put icon data inside .dot file (is it possible?)
Thanks for any help

Hi All,
I have an application where I want a WinForm to be transferred/reproduced in another machine and get the feedback from the person in the other machine.
This is useful for implementing approval for overrides from an approver.
Would highly appreciarte for useful clues/sample codes.

As far as I know there was none that was able to do what the VS IDE could do (forms building).
I heard of folks running editors like CodeWrite and stuff to alloww them to edit and build code, but nothing that did the GUI stuff.

ok, I'm just starting to learn how to pass more complicated things from my C++ objects to vb (which I'm just starting to learn).
Currently I can't seem to figure out how to get my safearray out of the variant passed through my callback interface. This safearray needs to be passed back through a callback interface ACROSS process boundaries (no passing by ref allowed).
_____________________________________
the C++ side of this is as follows
SAFEARRAY *saHashCodes;
saHashCodes = SafeArrayCreateVector( VT_I4, 0, nNumHashCodes );
for ( U32 index = 0; index
|
|
|
|
|
You should also specify the VT_I4
var.vt = VT_ARRAY | VT_I4;
In ServerLink_ReturnPrivateHashList function you can have your array in "saHashArray" parameter. It will be the array of Long (not Integer!) values. You can obtain any value from him
Dim i As Long<br />
i = saHashArray(0)<br />
' or i = saHashArray(x), where x = 0,...,nNumHashCodes-1<br />
' or i = saHashArray(x), where x = LBound(saHashArray),...,UBound(saHashArray)
Or you can obtain whole array, but it's the same in it's usage
Dim arr() As Long<br />
arr = saHashArray

excellent, it worked like a champ! 3 books, 2 newsgroups and about 4 irc channels later your the first person that could answer that. I really appreciate the help!

Hi
I have some procedure:
Sub SomeSub(ByRef somearray() As Double)
'some code, it doesn't matter
End Sub
I'm trying to call it in this way:
Dim somearray(10) As Double
SomeSub (somearray)
And I get such error message(it's my translation from polish, so it might be different on your computers):
Compilation error:
Argument of type Array must be passed by reference (ByRef)
I don't know what is wrong.
I almost forgot to add, all the code is runned as a macro in Word97
Greetings

Try adding the word Call in front of your routine call, this should do the trick, it works on my computer.
Private Sub Form_Load()
Dim MyArray(10) As Double
<code>Call</code> Some(MyArray)
End Sub
Sub Some(ByRef SomeArray() As Double)
MsgBox "Hello"
End Sub

Great thanks. It works, somehow, VB is very strange.

This small example will help to understand the role of "()" around the argument
Sub Func(ByRef i As Long)<br />
i = 12<br />
End Sub<br />
<br />
Private Sub Form_Load()<br />
Dim j As Long<br />
j = 33<br />
Call Func(j) ' ByRef<br />
Debug.Print "j="; j ' the output will be: j= 12<br />
<br />
j = 33<br />
Call Func((j)) ' ByVal<br />
Debug.Print "j="; j ' the output will be: j= 33<br />
<br />
j = 33<br />
Func (j) ' ByVal. Note that there is the <font color=blue>space</font> between function name and argument<br />
Debug.Print "j="; j ' the output will be: j= 33<br />
Unload Me<br />
End Sub
With best wishes,
Vita

Does anyone have any experience in using Leadtools twain for .Net? I'm struggling through their examples trying to figure out how to use the SetCapabilities option. The example that Leadtools provides is extremely confusing.

Anyone have any recommendations on some good VB.Net books? I'm an old school, top-down programmer trying to get into the swing of this object oriented stuff and would appreciate some recommendations on good step by step instructional materials. Thanks.

For the amount of learning curve required for VB.NET why not try C#, its a more of a purist language and fits nicely into the .NET side of things, also once C# is mastered you can all most program C/C++.
BTW: what's your language background?
Normski. - the next bit of code is self modifying ... jmp 0xCODE

My background is mostly with Visual Basic (up to version 6). I would prefer to stick with VB as it would be less of a learning curve for me, but I intend to learn C# in the future as I also have a bit of C, C++ background. The project that I will be working on needs to be written in VB.Net (as mandated by those who are funding the project)

Yes, I think regardless of whether you choose C# for development VBers should learn it at least to the extent of being able to read it. The reason is that some parts of the documentation and some utilities use C# only. And this also applies to some examples. With .NET, C# examples are now (in most cases) open to VB and it would be a pity not to take advantage of this merely because you can't read C#.
The same applies to a lesser extent to C#ers. They should be able to read VB.

Superficially, this seems true. You will be able to understand the basic syntactical elements. But C++ is way more complicated than C# and in fact you would still have a lot to learn to write C++ according to best practices.
I'm actually originally a C++ developer. But after spending lots of time with C# and then going back to C++ it looks awful by comparison.

I don't actually own it yet. But I've heard good things about "Programming Microsoft Visual Basic .NET" by Francesco Balena. Also I own his "Programming Microsoft Visual Basic 6.0" and it is very good.
Good luck.

As you said you are a programmer with VB 6 experience, I will strongly recommend Moving to VB.NET - Strategies, Concepts and Code by Dan Appleman and published by Apress (ISBN: 1893115976). Dan Appleman is a great writer, and he designed this book to help VB6 programmers move to VB.NET. I read it when I first started learning VB.NET and it really helped me get started.

You *MUST* pick up Programming Visual Basic .NET by Francesco Balena. Not only is it a comprehensive reference, but you can learn from it too.
I guarantee that you will keep this book around you for your entire VB.NET lifetime.
Don't listen to people who say you should learn C# - after you've gotten the hang of VB.NET you'll easily move back and forth between the two languages. I admit I like C# better since it is terse, but VB.NET is a great launching point if you are already a VB developer.

What, precisely, is the difference between the two? Both are meant to call the parent classes implementation of a member from a derived class, no?
*->>Always working on my game, teach me

You can use the MyBase keyword to call methods in a base class when overriding methods in a derived class.
The MyClass keyword allows you to call an Overridable method implemented in your class and make sure that implementation of the method in this class is called rather than an overridden method in a derived class.
Hmm...
