Hi,
am using a dll in my web project ("Owc11.dll")
Before upgrading our production server (32 bit) it was working fine. So, recently
our production server has been upgraded to 64 bit. So, while running the
application one error throwing like this:
"retrieving the COM class factory for component with CLSID {0002E55D-0000-0000-C000-000000000046} failed due to the following error: 80040154"
Anybody could you please help me asap.
These much ways i have tried,
1. dll registered in GAC also available in regedit.
2. Enabled 32 bit appln (WOW64) on 64 bit application pool by using .net command prompt. But i have 64 applns in the server. So left this method. (IIS won't support 32/64 bit applns at the same time).
3. Created Wrapper DLL and used by pre-binding method (act like interface b/w 32 bit DLL and 64 bit appln)
4. Handlers also used.
thanks in advance .
Thanks & Regards,

This normally means that it can't find the COM class factory. In other words, it can't find the appropriate DLLs. Open up regedit, and have a look for that CLSID in HKCR\CLSID.

Hi,
checked on CLSID in HKCR\CLSID.
DLL is available there.
So, what should i do ?
Thanks & Regards,

I assume a typo there in that surely you have upgraded to 64bit as having a 16 bit server still running is quite impressive, more than 17 years by my reckoning, that being when Windows NT 3.1 brought 32-bit into the world.
Two problems spring to mind, the first is that you will have a 32-bit interop assembly, not a 64-bit one. This is fine in a GUI based solution as you can compile for 32-bit and run in 32-bit mode, however on a server it is a little more tricky. You would have to pre-compile your web app for 32-bit, and even then you may have problems. When installing office it auto-detects your operating system and installs 64 or 32-bit as appropriate so even if you persuade your web app to run in 32-bit the underlying com object will be 64-bit. Microsoft have not released a 64-bit interop assembly package for office.
Final problem is that office automation will not work running under a service such as IIS on a 64-bit server, and that usage is not supported by Microsoft. Part of the issue is the manner in which 64-bit servers initialise the office process. They fire it up in the Administrator profile rather than the profile you are running under meaning that you will not be able to access any documents you try to open.
Not so much help, as bad news I'm afraid. We are facing the same issue, but thankfully are just starting to develop our app and so have no code to scrap.

i jst downloaded report viewer for visual studio and installed it but couldnt find it where it is?
|
|
|
|
|
In my installation of VS 2008 it shows up in the Toolbox under the "Reporting" heading as a control called "MicrosoftReportViewer".
If it's not appearing, you will need to manually add it to your Visual Studio toolbox. Right click somewhere in the toolbox and choose the "Select Items" option from the Contextual menu. When the "Choose Toolbox Items" dialog box opens, switch to the ".NET Framework Components" tab and find and select the "ReportViewer" option. Click OK and this component should now be available in your toolbox.
Hope that helps.

I want to invoke a stored procedure from a formula in my crystal report. And I want to pass a field of a table in the report as a parameter to it . So the return value of the stored procedure should be dispayed per a record.
In formula editor I don't know the syntax for doing that.Conceptually I want something like this:
exec sp_Test {MyTable.FieldName}
Is anyone know how the syntax is ?
I really need this thanks in advance.

I'm Using the following code to get the Que and wait times for a place I work for. If i open the address in a normal window im asked for my user name and pw. then i can see .xml file. But when i used the code below i get the error that follows it. I know it needs to some how have the credentials. This tool also has multiple web browsers logged into the same main site. and if i use any links within those browsers i don't even have to use my user name pw. Is there a way to just use the credentials automatically from say webbrowser1 and use them on this to make it authorize? If not can someone show me how to add the credentials so it will not 401 error. I wrote the app to be used by multiple people so the credentials are not always the same but always be what ever they used on webbroser1. I know my code reads the XML right because i saved it to my computer to use for testing. But ill be damned i if i can find the code I need to add in credentials. If someone could show me how to add them for this. im sure i probably figure out how to grab them from another window to be used here. Again im a total newbie on vb. I picked it because back in the day C64 I wrote basic lol. and realized it was something I could for simple things wrap my head around.
Dim que As XmlTextReader
que = New XmlTextReader("http://tracker.telenetwork.com/callmonitor/assist.xml")
'Used next line to test with Copied version from server to make sure xml reader worked.
'que = New XmlTextReader("c:\\xml\assist.xml")
que.Read()
que.Read()
Dim result = que.GetAttribute("queue")
MsgBox(result)
result = que.GetAttribute("maxwait")
MsgBox(result)
The remote server returned an error: (401) Unauthorized.
System.Net.WebException was unhandled
Message="The remote server returned an error: (401) Unauthorized."

What authentication method or methods is the
http://tracker.telenetwork.com server expecting
you to use?
You could maybe provide authentication credentials
something like this (C#, sorry  )...
WebClient webClient = new WebClient();
webClient.Credentials = CredentialCache.DefaultCredentials;
XmlTextReader que = new XmlTextReader(webClient.OpenRead(new Uri("http://tracker.telenetwork.com/callmonitor/assist.xml", UriKind.Absolute)));

I am very new in multithreading. I tried to read some topics but confused with different synchronization techniques used in .net multithreading like Mutex class, semaphore, critical section, event, wait handle and monitor.
Can any body guide me or can we do online conference or is there any in-depth video tutorial in multithreading ?

This will help Multithreading in .NET[^]
I will also add that WinForm / WPF, they are both thread unsafe and work on the UI thread (the one started in Program.Main() with a Run() method which act as a Window message pump).
To send message on the UI thread both (WinForm) Control and (WPF) DispatcherObject have a method called BeginInvoke().
A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station....

This is the formula on excel cell: =TestFunction(C2,F2)
Shows everything fine.
Can anyone please help me.

Ok, I have never understood this. Its an interface and therefore has no code in it...only 'stubs'. So when you implement it, it generates the Dispose method...and the Dispose method has code in it...how does this work? Id like to have my interface do something like this.
for example, create a class and implement IDisposable, press enter and it will generate the following VARIABLES and code blocks, not just empty subs.
Private disposedValue As Boolean = False ' To detect redundant calls
' IDisposable
Protected Overridable Sub Dispose(ByVal disposing As Boolean)
If Not Me.disposedValue Then
If disposing Then
' TODO: free other state (managed objects).
End If
' TODO: free your own state (unmanaged objects).
' TODO: set large fields to null.
End If
Me.disposedValue = True
End Sub
#Region " IDisposable Support "
' This code added by Visual Basic to correctly implement the disposable pattern.
Public Sub Dispose() Implements IDisposable.Dispose
' Do not change this code. Put cleanup code in Dispose(ByVal disposing As Boolean) above.
Dispose(True)
GC.SuppressFinalize(Me)
End Sub
#End Region

It's simple. The interface says that the object can be disposed before all references to it dies. The interface only says that.
But, the common all-purposes implementation (the Dispose pattern) says that:
Dispose() methods calls a virtual method Dispose that receives a boolean (true) and then calls GC.SuppressFinalize(this) and the destructor calls Dispose(false).
So, if you want your code to have somme implementation, you will at least need to implement a class (say MyDisposable) that implements IDisposable (so the using keyword can work with it) and implements Dispose to call:
Dispose(true);
GC.SupressFinalize(this);
And then, you make only the Dispose(disposing) virtual.
You can even make your "only call once" approach inside the non-virtual Dispose().

I dont know if I'm misunderstanding, or if maybe i posted my qustion wrong...basicly im trying to figure out something like this (VB)
public interface ISomeInterface
sub DoSomeStuff()
end interface
now when a sub class implements this i want DoSomeStuff() to have code already in it
public class MyDoSomeStuffClass
implements ISomeInterface
private mCanDoStuff as boolean = true ***i want this to be generated***
public sub DoSomeStuff() Implements ISomeInterface.DoSomeStuff
***Start Generated***
if mCanDoStuff Then
msgbox("WoOT")
End If
***end generated***
end sub
end class

I would ask on the Visual Studio board[^]...
There's probably an easy way to make a macro or something
that does this....I have no experience with that.

It's impossible.
Interfaces only says: The method exist.
You can, of course, do:
IMyInterface
(with some methods)
BaseClassThatImplementsIMyInterface
A class with virtual methods that implements the interface and, so, can create the basic functionality.
You can also create a helper class.
For example:
IMyInterface -> MyMethod
If your class comes from some other base class, it can implement IMyInterface and, in MyMethod, call
MyInterfaceBasicImplementation.MyMethod()
And, finally, you can create extension methods using interfaces.
So, for example:
IDictionary has the TryGetValue method.
I implemented a method called GetValueOrDefault as an extension method. It is NOT virtual, but as the TryGetValue is, it is enough for me.

It's not impossible, IDisposable does it. There is a way to do it, im just trying to figure out what that way is.

I think it is implemented using the CodeDOM. Visual Studio will be calling a custom code generator for inserting that snippet of code. Can't find it though. Found the stuff for generating the default constuctor code, typed datasets, and all sorts by using reflector, but not Dispose. Must be hidden away in the bowels of the framework.
A good article on using the CodeDOM can be found here[^]

Hey,
I'm creating a .Net download library. Part of the reason I'm doing this is to learn more about mulithreading. I've run into some things now that I'm not really able to solve, and can't find answers to, since it's pretty specific. I think my problems could be resolved after 15 to 30 mins of help by someone experienced with the involved aspects. If anyone feels like helping me out, please contact me.
