I guess you are telling me to plain use a FileSystemWatcher, because using it together with a service is something just not feasible when any file on the computer may be open.
Will this work? Always used FileSystemWatcher for being aware about changes in a file or folder since it starts working, I didn't know it could give information of the current status of a file. Anyway, wouldn't this need a lot of resources for just trying to open a file?
Well, I'll give it a look when I return at home.

When you open the filestream, request non shared access, it will fail then, and not later.
|
|
|
|

Well, that's what I'm already doing.
I'd like to know if there is some function (I don't care if it isn't a managed one) that directly tells if a file is locked by another application, that way I wouldn't need to use nested try...catch blocks.

Why do you need that? Just refactor the file opening process to a method and handle this specific scenario.

Do you do anything with unmanaged components in your code ?

yes i haved used ocx,dll and activeX controls in my application.
Any good practice in Assembly.cs file also??

One of those is what's crashing, so you need to look at your code that calls these.

are you using any 3rd party SDK's or .Net wrappers?

If your application is crashing and you want to solve the problem no matter what, I would suggest you throw messageboxes all over the beginning of your code. When a messagebox does not show when it is suppose to then that is where the problem is occuring. I am almost positive that most programmers would consider this a messy solution and would only use it as a last resort, it should be able to assist you.

I think you can use BringToFront() or SendToBack() for this.

sweet, worked perfectly... didn't know those methods existed...

Hi !
I'm trying to open internet explorer and show a web page on it .
I also want to post some data to the web page.
My problem is that I don't want to reopen a new web browser for the same URL. I want to reuse the same web browser and post some data to that url again.
I tried to use SHDocVw.InternetExplorer and SHDocVw.ShellWindows.
This is what i can do so far.
SHDocVw.InternetExplorer ie = new SHDocVw.InternetExplorer();
ie.Visible = false;
ie.Navigate2(ref vUrl, ref vFlags, ref vTargetFrame, ref vPost, ref vHeaders);
Is there anybody can help me ?
Thanks
|
|

|

Create this one times
SHDocVw.InternetExplorer ie = new SHDocVw.InternetExplorer();
ie.Visible = false;
use this many times
ie.Navigate2(ref vUrl, ref vFlags, ref vTargetFrame, ref vPost, ref vHeaders);
i hope this will help

Hi dhaim!
Thanks for your reply.
Maybe I'm not clear in explaning the problem.
I have a C# Console Application (this console application will launch internet explorer) that will be called by Access VBA.
So, it's not possible for the Access VBA to maintain the reference to the console application.
I need a way to read the current launch internet explorer and check the url and reposting certain data again to the web.
Could anybody help me to solve this problem ?
Thanks

try
{
smtpClient.Send(mailMessage);
}
catch (Exception ex)
{
eventLogImport.WriteEntry("SMTP Email error: could not send email.", EventLogEntryType.Warning);
}
Hi,
The above code still throws an unhandled SMTPException when smtpClient.Send is called.
SMTPException is derived from System.Exception so should it not be caught?
Thanks
|
|
|
|

Hmmm... if the smtpClient uses another thread, this won't be caught, you need to actually set a handler for exceptions from another thread.

Interesting.
This is occuring in an event handler, however i thought the method which triggers the event should be on the same thread. I'll look into it as there is some SQL data access going on which may make and asynchronous call.
Thanks!

Interestingly enough, I see that the first thing this does is start off a new thread. As Christian said, this could well be the issue. Try using Application.ThreadException to catch the exception.
