Do you mean that you want to re-invent Word and Excel, or simply use their application interface to programatically automate their functions?
If the latter, I strongly recommend Visual Studio Tools for Office - available from MSDN. This greatly improves the 'programming experience' whilst working with Office applications.
If the former, then I'm afraid this is not the forum in which to ask that question. In fact I think you'll be wasting your time and energy since there are already viable alternatives to Microsoft Office (see OpenOffice.org[^] for an open source variant).

error msg Name 'CommandBehavior' is not declared.
objReader = MyCmd.ExecuteReader(CommandBehavior.CloseConnection)
how can i solve it..
|
|

I think it's quite obvious. You don't have an object, or other type, declared with the name CommandBehavior. Perhaps you're missing an Imports System.Data line at the top of your code?

For a start you could try looking up the error in the Visual Studio help. Saves a lot of time and energy - and doesn't clog the forum with unecessary posts.

i have a custom TTS in dll form,
if i want to implement MS SAPI interface, so my custom TTS have the same interface with MS SAPI, what should i do?
thx...

What? Are you asking how to make your custom Text-To-Speech engine expose the same interface as Microsoft's Speech Api? Are you asking how you can replace MS's TTS Engine? Or what?

Sorry before if my question is confusing...
What i want to ask if, how to make my custom TTS engine expose the same interface as MS SAPI? The problem is i have my custom TTS in dll form, so i cannot change the way it behave. What i want to do is to wrap my custom TTS in another dll maybe, so it has the same interface as MS SAPI. And i think the way to do it is to implement MS SAPI interface, but i don't know how? Is it clear enough? Thanks...

This is going to be a nightmare! You DO NOT want to replace the engine! This will create such a huge mess it's not worth it. You'd have to replace the registration of all the engine methods and properties exposed to COM with your own. This means duplicating GUID's and names, but pointing the GUID's to your COM server. Good Luck! There's hundreds(!) of them.
You'd have to implement everything exposed by the MS SAPI classes, providing the same functionality that clients using the MS library would expect.
You'd be much better off just completing your own library and not trying to "shoe horn" your implementation into MS's. Your library can run side-by-side with MS's.

Is it that hard? Can't i implement just several methods like speak, stop etc?
All i want to do is, if people want to use my TTS then they can use it the same way as they use MS SAPI, with several exception of course.

No, there is NOTHING simple about this. You would have to change the registration keys and values of the methods and properties you're replacing and point them to your engine code (hopefully written to be exposed to COM).
You're MUCH better off just finishing your implementation and seperating yours from Microsoft's entirely. This way, your library is at least supportable and has no dependancies on other peoples/company's code. MS's library can change without notice and render your library completely useless in an instant.

Hi,
I have created the folowing functin from my form to call a class in another project within the same solution.
this line (sections.GetRiskSections()) is underlined and the error is:
Error 1 Value of type 'RSCompDB.Premiums.RiskSectionsList' cannot be converted to '1-dimensional array of RSCompDB.Premiums.RiskSectionsList'.
Thanks
Public Function GetRiskSections() As RSCompDB.Premiums.RiskSectionsList()
Try
Dim sections As New RSCompDB.Premiums.clsPremiums()
''''ERROR''''''''''''
Return sections.GetRiskSections()
''''ERROR'''''''
Catch ex As Exception
Throw
End Try
End Function

It is simple! Tabcontrol has a selectedIndex change event that is where you can control the index as stated below:
Dim GetIndex as Int32 = Nothing
Dim SetIndex as Int32 = Index numger goes here
GetIndex = Tabcontrol1.SelectedIndex
or you can set it to
Tabcontrol1.SelectedIndex = SetIndex

Hi all,
There seems to be a problem with Crystal Reports that comes packaged
with VS2005. Crystal has acknowledged the problem and assigned a
tracking number to it (early '05).
The problem is this, or in my case anyway, when I use a report that
I create I can pull the report up and everything is fine when
running the app on my development machine.
But, when I give the app to another machine it displays a logon screen and it does not matter what you type in for a username or password it will not accept it.
I am sure that I have all the files that are needed to be packaged with the app otherwise the CR logon screen would not be there and it would error out or something.
Just wandering if anyone else is having this problem and what you
might have done to get around it?
Thanks in advance,
-----------------------------

HI
Is there a way to stop the Combo's SelectedIndexChange event from firing when you bind a datatable to a combobox?
This does NOT work:
Me.cboProductCode.BeginUpdate()
Me.cboProductCode.DataSource = dtBmasshm
Me.cboProductCode.DisplayMember = "WPD"
Me.cboProductCode.ValueMember = "WP"
Me.cboProductCode.EndUpdate()
Thanks
Richard

Nope. The SelectedIndex is reset every time you bind the data to the box. You can't stop it from firing.
You can, however, set a flag in your code that says that a bind is taking place. In the SelectedIndexChanged event, you check to see if that flag is set. If it is, skip the rest of your event handler and and reset that flag. The next time your event handler is called, it'll know that a bind is NOT taking place and it should proceed normally.

You can also remove the handler for the selectedindexchanged avent before you change the binding
removehandler me.cboproductcode_selectedindexchanged, addressof cboproductcode_selectedindexchanged
Me.cboProductCode.DataSource = dtBmasshm
Me.cboProductCode.DisplayMember = "WPD"
Me.cboProductCode.ValueMember = "WP"
addhandler me.cboproductcode.selectedindexchanged, addressof cboproductcode_selectedindexchanged

You can use the System.Windows.Forms.Screen, AllScreens property to get an array of monitors, each with it's own WorkingArea (hint, hint!), to set the Location and Size of each of your forms to different monitors.
This will enumerate the screens and show you their working areas:
Private Sub Form_Load(blah, blah) Handles Me.Load
For Each Scr As Screen In System.Windows.Forms.Screen.AllScreens
Debug.WriteLine(String.Format("Screen {0} has a working area of {1}", Scr.DeviceName, Scr.WorkingArea))
Next
End Sub

Thanks for the reply
Using youre code I get information about the primary screen.
Could you please help me with what I should do next to show my two webpages in different monitors.
I would like to display them fullscreen.
PS The web page in the main screen is fullscreen, but if I set the other webpage to full screen it displays over the firs webpage, how do I get it to display in the secondary monitor?

I don't have a dual screen machine to test any code on. Sorry...

No prob
Could you describe a way to solve my problem?
Hint or tips...
I am completely lost about what to do.
I can place my second webapp where I want on the secondary monitor. But not get it to go fullscreen. Beacuse it overlaps the first webpage..
Thanx
