Hi,
I have been facing an issue while using CDOEXM.dll from my .NET Framework 2.0 code (written in C#). We are trying to create a mailbox on an Exchange Server (which is 2003). We have checked for correctness of the code in terms of NULL value etc. The code which gives the error is below:
CDOEXM.IMailboxStore mailbox;
mailbox = (IMailboxStore)User.NativeObject;
mailbox.CreateMailbox(maildb);
The error message that we get is:
Unable to cast COM object of type 'System.__ComObject' to interface type 'CDOEXM.IMailboxStore'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{25150F41-5734-11D2-A593-00C04F990D8A}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))
I would like to emphasize that the very same code has been running on .NET Framework 1.1 without any issues. I understand that there is a typecasting issue, but I am unable to understand that how to resolve this.
Any help will be much appreciated for this long drawn issue. Please let me know if you would like to get any more information from me.
Cheers,
Som

I found this sentence in this[^] article: "This cast does not succeed at run time if CDOEXM is not installed on a computer". Have you checked that?

I checked in the Global Assembly Cache, but could not find it. I am referencing that DLL as a private assembly. Is there any other way to check if it is installed on the machine?
N.B.: This code used to run when in .NET Framework 1.1 on the same machine and on the very same configuration. So it is a bit concerning as to how it used to run if the CDOEXM.dll was not installed? This makes me think if there is any known issue with .NET Framework 2.0 and CDOEXM.dll? Are you aware of any?

Since CDOEXM.dll is COM it is not a suprise that you did not find it in the GAC. I think you might try to remove the reference of your project, delete de previous interop assembly you had and, then, add the reference again. This should create a new interop assembly and maybe your problem will disappear.
The best I have found about this topic is this[^], which you will probably know. It says that CDOEXM needs MS Exchange Administrative Tools to work properly.
Maybe there is an issue with .NET framework 2.0 and CDOEXM, as you say, but I am not aware of any. Sorry I cannot give you any further information.

How to call my disk part commands from c# and redirect output to xml file.
Urgent.
|
|
|
|
|
To call Diskpart commands and redirect its output you can use the Process[^] class.
To parse the output to a XML file you have several classes at System.Xml[^] namespace.

hi everyone..
I want a tool to plot real time graph fr .net platform.The data which has to be plotted is continuously coming in some time interval.Is there any tool available?
Also Performance issue is there.Performance also matters when I am using the tool.
Thanks in adv...

Although there may be such a library I am not aware of any.
There are, however, plenty of graphing libraries out there, Microsoft even has their own[^].
It seems to me that it would not be difficult to handle the data input and pass it to any of the available controls/libraries.
If this is not useful to you you might edit your question to indicate how the data arrives since it is not currently clear if it arrives from t'internet, down a serial wire or by mail.

actually data is coming from a hardware(or say lower layer) through LAN.Hope it would be clear.

You have answered the wrong person.

I found the same idiot responded with the same answer to several of my posts today. Just a spammer... He's been assimilated, per SOP.

if you need to plot incoming data in real-time, you need to be prepared to build a solution that is multi-threaded so that you can handle the actual drawing and the processing simultaneously from the user's perspective.
As per Henry's question, this will also depend on the frequency at which the data packets arrive. Is is a millisecond window, or seconds, or minutes? This will determine the type of solution you require.

it is coming in milisecond.and also performance also matters for graph.Can Any external tool be used??

Please see the post from flflshop answering one of mine. He links to a site that he says can help you.

You can convert a byte array to a string using:
System.Text.Encoding.Unicode.GetString([byteArray]);
Note: Unicode is just one of the encodings. You can use ASCII, UTF8, etc

Actually that not his requirement.., He wants to read the information in PDF Document ...

You cannot read a PDF file in this way. A PDF file is a structured file containing objects that define pages, strings, images, fonts etc, with an index at the end of the file that allows quick random access to each object. You can get a copy of the PDF specification[^] from the Adobe web site, or use one of the free PDF libraries such as iTextSharp[^].
Just say 'NO' to evaluated arguments for diadic functions! Ash

How do you intend to define the location and content of the string you want to capture? I ask because the pdf format converted to a byte array isn't a plain text stream, it is binary data, which will make handling the data potentially problematic.
I wasn't, now I am, then I won't be anymore.

Hi,
Sorry for asking a powershell question. This should be easy for an expert.
Suppose I'm in the folder C:\Windows\System32 . I want to print out only "System32".
I have found commands that give the entire path, but I want only the last bit.
Thanks,
Mel

You have posted the same question on 4 different forums; please, don't do it!
The best when asking something is to choose the forum that better matches your subject, and post a unique question explaining as better as possible what is your problem.
Thank you!
