I don't know how it is linked to Word but try the following:

Troubleshooting "RPC Server is Unavailable" in Windows

RESOLUTION
To resolve this issue, follow these steps: 1. Click Start, click Run, type the following line in the Open box, and then click OK:
net start rpcss
Test to see if this resolves the issue. If the issue still occurs, continue to the next step.
2. Click Start, point to Programs, point to Accessories,and then click Command Prompt.
3. At the command prompt, type ping servername, where servername is the server, NetBIOS, DNS, or GUID name that you want to test for connectivity.

If there is a connection issue with one of these computers, contact your network administrator to resolve the issue. If the issue still occurs, continue to the next step.
4. Use the Netdiag tool that is included in the Microsoft Windows Support Tools (included on the Windows CD-ROMs) to determine if the domain controller is working correctly. You can perform a network trace using the MSRPC, DNS, NBT, LDAP, or TCP protocols.

If there is an issue with the domain controller, contact your network administrator to resolve the issue. If the issue still occurs, continue to the next step.
5. Use the Netdom tool that is included in the Windows Support Tools to verify network trust relationships and reset or establish a connection to a server.

This is probably caused because your code didn't shutdown and free up the Word object when you closed your application the first time.

Thank you Deepak

I tried the hotfix provided by microsoft but it didn't fixed the problem. but finally i found the solution which is

object = nothing does not release the com resources properly so instead of using this way i used

Marshal.ReleaseCOMObject(object) (.net version 1.1)
Marshal.FinalReleaseComObject(oApp) (.net Version 2.0)

a very helpful article is available at following link

I am using Crystal Reports in my application I made using Visual Studio.NET.
I installed my application on the client machine, with all the DLLs
required(added the merge modules), the engine and the rest. When I start my
application and, from it, try to open up a report I get an exception "Query
engine error: C:\WINDOWS\Temp\temp_*******.rpt" with some wierd numbers
instead of *******. Can anyone tell me what the problem is here and how to
solve it. I am running the application on Windows 98.

Hello All,
Well i am working with collections in the project.
I have set the datasource property of the datagrid to a collection (I am not using dataset just the collection).
I am unable to format the datagrid using the tablestyles.
Would anyone please help me in formating the datagrid (using tablestyles) when the datasource property is set to a collection.

Thanks in advance,

P.S - I am unable to set the mappingname property in the tablestyle to collection.
if you send a mail at gokhale.i1@gmail.com in response to this query it would be better...

If I remember correctly, you can't. TableStyles only work with DataSet and DataTable objects, not user collections. The MappingName property must match up with the TableName property of a DataSet or DataTable object, which your collection will not have.

FRACTAL FORMULA HELP REQUESTED

FRACTAL FORMULA HELP REQUESTED

Hey folks!

I am hoping to experiment with some simple fractal formulas in VB. I have some running ok, but some
I seem to be having trouble with. I am using VB 4.0, and am hoping someone out there in cybertopia
might be able to share insights or code snippets? I don't need anything fancy like complex graphic
rendering of the fractals, although if you are excited about this stuff and feel ambitious I'm happy to
check out any graphic stuff you might want to share.

Simply, all I'm looking for is simple number in and number out routines, i.e. you stick a number(s)
into the formula, set the iteration ceiling and then watch what ever numbers get pumped out, thats it really.

So we might have say two text boxes for inputs,

textbox1 = any number value, i.e. 129
textbox2 = any number value, i.e. 234

Then we feed those values into the fractals formula loop and for every interation the newly generated
values get dumped to some other textbox.

=================

Barry Martin - Hopalong

This one is probably one of the most interesting ones, it seems Barry Martin released a really old dos version called hopalong
and there are various exe takes on this floating about, but most of them don't work anymore because they are so old.

I had trouble with this one because I don't really understand the "sign" function, and the VB 4 sign function doesn't seem
to work in a way thats compatible with the formula, but then I'm just as likely ignorant of how to properly apply it.

2 plots resemble organic structures like cells

xnew=y-sqrt (abs(b*x-c))sign(x)
ynew = a-x

different values for constants a,b,c give different patterns and periodicities
========

For the Lorentz function, I'd like to get a really simple rudimentary one working, but I'm also curious about what would happen
if we had two parallel Lorentz functions working together, one accepting outputs from the other and then feeding back into the first one,
i.e.

Lorentz function (1) outputs cycle iteration values to Lorentz (2)

And then Lorentz(2) inputs to Lorent(1) and so on.....

By the way, does anyone know if a single Lorentz function can operate on more than the default # of inputs

Lorentz Function

xnew = x+d*a*(y-x)
ynew = y+d*(x*(c-2)-y)
znew = z+d*(x*y-b*z)

where a,b,c,d are contants, i.e. values of 10,8/3,28,0.003
========

I tried coding this one also, but instead of getting a rich set of chaotic values all I got were two values
that repeated exactly the same over and over again????

Mandlebrot

z ; iterate via ; z^2 + c

==========

For this one I tried implementing this but for some reason, when I coded this to VB, it only generated
the same values over and over again.... no chaotically generated values......
(folds and remaps oval onto itself
)

xnew = y + 1 - 1.4 * x^2

ynew = 0.3 * x

Step One: Upgrade your version of Visual Basic. Visual Basic 2005 Express edition is free and accessible, vb 4 is seriously outdated, insufficient and unsupported for anything. VB.net 2005 is much more effective for any application, it is now much more than a glue and paddlepop sticks microsoft response to a more "understandable" interface and has become nearly, if not as, powerful as C.

http://msdn2.microsoft.com/en-us/express/aa718406.aspx

Step Two: Try the maths forum, right here on Code Project.
Any thing mathematical, those guys can help. Oh and try to make your question abit more concise.

Yeah, it's called a "menu item". You open your text file, then create items in your File menu from that. There is nothing to do with a "mouseover" event. What's the problem??

when the mouse hovers on the recent files menuitem, as you know you get a submenu with the list of recent files. how do i get the list to read into the recent files submenu from the text file.

sorry to be a pain in the rump.

Dave Kreskowiak5-Sep-07 8:36

Create a menu item under your File menu with a name of, say, RecentFilesMenu and some appropriate Text.

Here's an example of adding submenu items to a menu:

RecentFilesMenu.DropDownItems.Clear()

For x As Integer = 1 to 5
    Dim filename As String = String.Format("Filename{0}.txt", x)
    Dim newItem As New ToolStripMenuItem(String.Format("&{0} {1}", x, filename), Nothing, AddressOf RecentFile_Click)
    newItem.Tag = filename
    RecentFilesMenu.DropDownItems.Add(newItem)
Next

You'll, of course, need a method to handle the clicking of those menu items, so....

Private Sub RecentFile_Click(ByVal sender As Object, ByVal e As System.EventArgs)
    If TypeOf sender Is ToolStripMenuItem Then
        Dim menuItem As ToolStripMenuItem = DirectCast(sender, ToolStripMenuItem)
        Dim filename As String = DirectCast(menuItem.Tag, String)
        ' Call your Load Document code here...
    End If
End Sub
