Are you using the old xmlreader and xmlwriter?
If not then why do you "open, read, close" then "open, write, close" ?
|
|
|
|
|
I'm using the xmlDocument Class. When i want to save with xmlDocument.save() that error happens
|
|
|

Im willing to bet that you've not disposed properly of the stream when you open the file, hence when you come to write it there is already another process holding onto it (ie, your own program from earlier on during the read op)
|
|
|
|
|
Thats not the case, because it does not happen at all if i don't open the explorer and look into that folder.
|

once you call the load() method the file should no longer be accessed...
Again I don't see why you "open, load, close" then "open, write, close"
You should be fine with it in ram after you load it. "open, load" do your other stuff "append new data, close"

I tried it. But it doesn't have an effect.
Here is my code at the moment:
XmlDocument doc = new XmlDocument();
doc.Load(FullFilePath);
.......
doc.Save(FullFilePath);

Does it error if you try to write to a different file path? (one you know you have write access to)

Hi,
if you want write or delete access (anything other than read access) to a file
that just got created (by yourself or someone else, does not matter),
chances are you will find the file is being accessed by some other process,
and your access is not granted.
Yhe other process very likely is some server code that is there to assist you
somehow. Candidates are:
- anti-virus software (Norton, McAfee, whatever)
- indexing software (Google Desktop, MS Office, whatever)
The common thing is these packages are looking all the time for new files, so
they can inspect them.
Microsoft is aware of the consequences; Windows Explorer will try rename and
delete attempts up to five times (with one second interval), and only reports
failure if the action continues to fail for that time.
The solution:
1. either use a different file name
2. or remove all background reader candidates (bad idea)
3. or implement the retry loop as Explorer has it (use a Windows.Forms.Timer
for this)

- make Visual display line numbers: Tools/Options/TextEditor/...
- show exceptions with ToString() to see all information
- before you ask a question here, search CodeProject, then Google

1. and 2. are no solutions for me.
I have to try 3. I think. I hoped i don't have to use a timer

ASP.NET is a framework. C# is a language that can be used to write ASP.NET applications. Are you asking how to communicate between the ASPX page and the code behind?
If not then you really need to explain better because I don't understand what you are asking.

the problem is this. some people must use aspx web page to chat. and some people must use a windows application like msn messenger. for exmple, i will use msn messenger to chat with you, and you must use an aspx web page to chat with me. maybe this is more clear

It can be done, and the general practice is to have a central server with 2 types of client:
web: pings for new messages (possibly using AJAX)
windows: gets messages pushed to it from server.
Start with an example of a straight windows forms chat application - there will be plenty online - and build the web client when you are more knowledgable on cthe chat software.

Can anyone help me with this error. It appears to happen when I try to create an istance of the UPnPDeviceFinderClass.
Creating an instance of the COM component with CLSID {E2085F28-FEB7-404A-B8E7-E659BDEAAA02} from the IClassFactory failed due to the following error: 80070422.
My application searches a LAN for uPnP devices, for some reason it works fine on most computers but there are a select few that I get the above error.
Freedom is the right to say that 2+2=5 if this is so everything else will follow.

...I would assume that you are using the 2.0 Framework? ...It has been suggested that that error is caused by a bug in the framework. There's a hotfix available here ...Apply it and see if your error disappears. If it does, come back and let everyone know. If it doesn't, then I'm out of ideas.
