Have you tried logging on as the same user as the service runs under and sending a fax?

Change the account the service is running under to your own. Then you should be able to see the fax in your outbox.

I have just struck the identical problem.
ConnectedSubmit works fine in a harness app, but becomes a black hole in a Windows Service.
EventLog statements sprinkled through code before the submit are visible, nothing after. No exceptions caught. Service responds to stop.
A threading issue? (My code was kicked off by a timer.) Issue with unmanaged underlying COM?
Have you a solution?

Have any of you got into this problem?
I've got a .Net 2.0 Winform app for tracking days off and resource management, I'm using Microsoft Application Blocks to connect to an Access db, providing connection string and everything works just fine! Issue is, some of my users have been required in their projects to install Teradata(v 12) which has caused that the application cannot open the Access db. I know, for the type of company and customer they have, that their machine conf is exactly the same, the pc's are configured the same with software installed from the same image, and none of the have admin rights, so I know that it's because they had Teradata installed that they are facing the problem. People that has not required yet to install it are working happily with my app.
Any insights or ideas will be very much appreciated!

Just a SWAG, but the only thing I can imagine that might be affecting this is that the Teradata package has installed a different version of the Jet engine, one that isn't compatible with your software. Can you get a copy of the Teradata stuff and install it on one of your own machines for testing?

Compare the Jet Database engine version if your Dev PC and in the PC where your app doesn't work, most probably, your Jet engine DLLs must have been overriden with different versions. Here's a link that tells your how to check the Jet DB version: http://support.microsoft.com/kb/141796[^]

Unless you code it up that way explicitly, an event hook is a strong reference, not a weak one.
As for hooking the delegate itself, yes, as long as object A has a reference to object B, it'll keep object B alive.
You can avoid this by using a WeakReference in the variable behind the DoStuff property. You'll just have to verify that the reference is still alive before attempting to call it.

The .NET garbage collector is actually quite good. It can clean up objects that are holding links to each other (keeping each other alive via A holds a reference to B and B holds a reference to A again).
When this pair gets orphaned from the memory root(s) (i.e. there is no path of references from the base-objects of the program to the A-B pair) then the garbage collector will see that this pair is cut off from the rest of the program and thus clean it up (as always, when this clean up is done is not predictable).

Technically speaking it isn't a memory leak. Worst case, posterObject wont be garbage collected until Listner is disposed. It's definiately something to consider but once the applicaion is closed, there will be no memory leak handling events in .NET.

Hi everyone,
I've got a problem when trying to include a CSS file from within a HTML file when the HTML page is loaded as a resource (see below). I'm writing the application in VB.NET, it basically loads the HTML in a web browser control fine, but if I try to include a CSS relative to the EXE or HTM file the stylesheet does not apply.
Dim objMemoryStream As System.IO.MemoryStream
objMemoryStream = New IO.MemoryStream(System.Text.Encoding.Default.GetBytes(My.Resources.wpHtmlPage))
wbApplication.DocumentStream = objMemoryStream
The only way I can get this to work at them moment is to hard code the full path to the CSS file (see below), what I'd like to be able to do is either make it relative (and work) or add the CSS as a resource but this fails to work as well.
<link href="C:/temp/styles/default.css" rel="stylesheet" type="text/css" />
Any help or/and advice on this would be much appreciated, thanks.

Hi Jonathan,
You are displaying the Html page by reading it from a resource file as against the file being rendered by a web server. There is no location from where your html can locate the css file.
One solution is to save both the html file and the css file to a temporary folder and display the html from there (I believe the WebBrowser control has a Navigate method or so).
Alternatively, you can use inline stylesheet using the <style> tag.
|

Thanks Shameel for your quick reply.
If what you're saying is correct (and it does make sense to me) and there's no other solution I think I will just have to include the CSS code within the
<style> tags.
Unfortunately, this just makes the management of the style harder as I'd have to tweak every HTML file as and when required. 
|
|
|
|
|
Or you can explore the other option I suggested, i.e., save both the html and css files in the same temporary folder and use WebBrowser.Navigate(<<html path>>).
|
|
|
|

If this is a winforms app, and you're using the web browser control, you MUST supply the fully qualified path to any style or javascript file you want to load. I do it this way:
string html = string.Format("<link rel='stylesheet' type='text/css' href=\"{0}\" />", System.IO.Path.Combine(Application.StartupPath, "myFile.css"));
If you made the css and html files embedded resources, they will be extracted when the program runs to the executable folder. This way, you can use the Application.StartupPath as the path to the files.

I'm trying to have plugin functionality in my application. So first thing came in mind was to just load the DLLs and call the common abstract class methods. After completing all that, I noticed that there could be many security issues. The next thing I used was different AppDomain. But that solve half of problem. Assume this, if a plugin wants to connect a server over internet, the firewall will show the name of my application and user may allow without knowing its the plugin who is trying to connect. After that I started using NamedPipeStream, separated them in processes, connected plugins and application through PipeStream, it does exactly what I needed but each plugins means a different process.
Even everything is working fine but its not satisfying, something still feels not so good. My question is, is that the only way ?
PS : I just want simple plugin support, not some complicated library like System.AddIn.

Simple for you may be altogether different for someone else. I googled "C# plugin framework" and got 17 million hits back, and on the first page, I found this:

I'm not sure why this was downvoted. MEF was going to be my recommendation as well.
