I understand how you wish that it would work. I want you to explain how in the world you can expect it to work that way?

I have already told you that the reader can't close the file until you tell the reader that you don't want to use it any more. If you just leave it hanging halfway through the read, it doesn't know that you have decided not to read anything more.

It's just like if you pack up your car to go to Alaska, but halfways you run into a roadblock telling you to take another route. If you just step out of the car, leave it running and go to find a bar instead, the car won't figure out that you don't want to drive any further and shut itself down. It will just keep waiting until it runs out of gas.

The same thing happens to the reader that you left hanging. It will just keep waiting until the garbage collector comes and tells it to pack up and go.

that's just silly. surely you can see the difference between a function called "File.Open" and one called "XmlReader.Create".

For my last 10+ years of C++ and C# development both a Create and Open interface will open a file. Open opens an exising file and File.Create creates a new file which is then opened.

It may be poorly documented, but it is consistent with my last 10+ years of experience with a Microsoft development framework.

Your right about the class being poorly documented. It's not a bug with the class, but with the people who wrote it.

In the XmlReader class, there is, thankfully, a property called ReadState that you can check in your code to see if the was actually opened or not. The possible values are Closed, EndOfFile, Error, Initial, and Interactive. Docs on it are here[^].

You can either use Guffa's version or just call the Dispose() method on the XmlReader in your catch block. If the file hasn't been opened, nothing will happen if you call Dispose on the reader.

Changed Close to Dispose. That's what I get for spending entire day and night writing in VBScript...

Hello all,

I'm using .NET 2005 and I have to convert a collection (CustomCollection) into a List, from Generics. I don't seem to find anything about it... Has anybody any idea if it is possible to do this conversion without copying every object from the collection to the list (only a conversion) and if it's possible... how should i do that??
Please help... Confused | :confused:

Thank you!
Roxana

Hi,

basically you will have to copy the contents. You could make this by either copying everything yourself or by using the CopyTo method of the collection to copy everything into an array and than either using the appropriate List constructor (one of them takes any IEnumerable) or using AddRange.

I get the following error when compiling some of the projects in my solution but not all.

'A strong-named assembly is required. (Exception from HRESULT: 0x80131044)'

Can someone tell me what this means and provide some suggestions on how to resolve this?

thanks,

Automatic copying of dlls

hi,
i have two different projects. One project dll is required in another project's bin. But i cannot add a reference because of cross reference. Is there any way where after i compile the solution automatically the dll from one project gets copied in another project's bin? Currently i have a batch file which does this job. Can i integrate this bat file with my .net IDE so that it executes everytime after i compile?

Its bye for now..
Signing off.

Look in the Project Properties, Compile options, Build Events. You can execute your batch file from there.

Hi
I am using static binding i.e the use of dll of MS OUTLOOK 2003 in my Windows application to extract FROM,TO,CC,BCC,MESSAGE email addresses and their names etc. and store it into an MS ACCESS database. The module is working fine in my machine and also in client machines, but some of the clients are complaining that they are getting the error at the time of running the module. They are also using MS Office Outlook 2003. They are getting the error when try to run the application.

The error is like this:

System.IO.FileNotFoundException: The specified module could not be found.

I think sometimes CLR fails to load unmanaged dll of OUTLOOK. I have tried by using most of things but till now there is no success. All the dlls are present in applications root folder.

Is there any idea?

regards

You could try using the fusion log generated by fuslogvw[^]. You can track which assembly is missing and then figure out if any of its (managed or unmanaged) dependencies are missing.

The log shows that TestApp.resources assembly is not present in the assembly probing paths. You need to make sure that assembly is present in one of the paths from which fusion is attempting to download the file.

Exclude labes from versions (VSS API)

CWIZO3-Oct-06 20:08

I'm working on a program that takes some files from one VSS database, does something with them and puts them into another VSS database.
Everything was working until I triedy my program on a VSS project that had labels defined.
My code searches for the latest version of a file. And if a file has some versions and a label which is the newest, I get the version number of that label. And I can't get a file based on the label. I need the latest version of a file even if the latest thing is a label.

I would like to know if there is a way to exclude labels from the collection that get_Versions returns or how can I find out if the current version object (inside a foreach loop) is a label.

My code looks something like that (relevant part that is):

System.Collections.IEnumerator versions = vssFile.get_Versions ( 0 ).GetEnumerator ();
versions.MoveNext ();
int latestVersion = ((IVSSVersion)versions.Current).VersionNumber;
latestVersionFile = vssFile.get_Version ( latestVersion );
string saveFileName = savePath + "\\" + latestVersionFile.Name;
latestVersionFile.Get ( ref saveFileName, 0 );

Count a process network traffic

Dose anybody know how its possible to get a traffic used by specified process pid or name ?

Dave Kreskowiak3-Oct-06 10:13

3-Oct-06 10:13

No, it's not. Those statistics don't exist anywhere, unless the application itself is keeping track of them.

You could, on the other hand, attach performance counters to the process and start monitoring them yourself, but those stat's don't exist "automatically" when you start a new process.

The docs on the PerformanceCounter[^] class.

Google for "performancecounter vb.net[^]" for a bunch of examples on how to use it.
