No, I can't. There simplly isn't enough space in a forum post to cover everything WCF does and how to do it.

WCF doesn't encompass just one method of communicating. It's a suite of classes that encapsulates many methods of communication.

how to build the dynamic webreference via NANT build script

mukkil12-Aug-10 7:20

Dear all,

I have inherited a web app project that makes use of a number of WCF Web Services hosted on a remote server. We have two environments that I need to deploy this project to, with different URLs for the different remote servers.

i.e. In the Staging environment, I need to point the services at xx.xx.xx.101
In the Live environment, I need to point them at xx.xx.xx.102, or whatever.

Currently, we've got all of the URLs stored in keys in the web.config file, so that we can change them dynamically... Unfortunately this isn't working!

If I change the URL in the web.config to something other than what the project was compiled with, I get an error when calling the web service:
Server did not recognize the value of HTTP Header SOAPAction: xx.xx.xx.101\ServiceName\MethodName.

During the .NET conversion process from 1.1 to 3.5, there is a Auto Generated web reference source file (Reference.cs under web reference) that contained the logic to get the correct Production URL for configuration file (web.config).

The problem is this logic seem to be replaced with a manual hard code referencing test webservice URL. Regarding how this happened still seems to be a puzzle which is hard to find as this file was supposed to be auto-generated and no manual edits should have taken place. This was not encountered in TEST environment as the unit test scenarios covered Common test accts.

It's driving me mad! I've written a pre-build NAnt script to go through and replace all instances of the URL found anywhere in the project directory, and even that isn't making any difference.

There must be something else being pulled down from the service when I click the "update reference", but I'm new to working with web services, and so I'm not sure what.

Does anyone have any ideas? Is there a way to do this programatically?

How to force printer "Microsoft XPS Document Writer" to print in a file without inquiry for the user of a filename

Windows XP SP3; .NET Framework 3.5 SP1; Microsoft Office 2007; C #.

At attempt to print a file through printer "Microsoft XPS Document Writer" to the user the dialog box "Save the file as" in which it should enter a XPS-file name is output. What it is necessary to make, that the printer printed at once in any file without inquiry for the user of a filename?

For example, for the printer "Microsoft Office Document Image Writer" after record in a register key "HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\ MODI\MDI writer" in parametre "OpenInMODI" values "0", the printer starts to print in a file "Note.tif" without inquiry of a filename for the user. It can be possible to make something similar and for printer "Microsoft XPS Document Writer"?

The mechanism of the XPS-press includes 2 components: the XPS-printer and XPS-port (and is named XPSPort - can look in properties of the printer) - last does exactly one thing, writes turned out XPS-document in a file (and from the XPS-printer goes already valuably serialised XPS). The important consequence From here turns out: if to route output to standard port of type FILE, or even to make local port it is possible to write files at the desire.
There is a problem of a pop-up window. Unfortunately, the unique way without development which has been found is to create on the basis of the standard driver the type of the printer, having taken the standard interface unit, the standard driver...
In the attached file there are necessary files for printer installation. After printer installation it is necessary in properties of the printer to set output in local file port, preliminary having created it.
Everything after that it is possible to print through the new printer in the set file without inquiry of a filename.

Install DDK (WDK) and modify the sample printer port driver. Inside it you can control the output filename.

- Create e.g. a DialogBox.
- Open the DialogBox on clicking the Button.
- Let the user put in data on the DialogBox.
- Validate the data.
- Add/Insert this data in the GridView.
- Update/Sort the GridView.

Hi,

I want to write a small application that receive video stream and can isolate the video frame.
Is there some .net component that can help me to do it ( something like MediaElement ) ?

Thanks

FileWatcher class and WMI

NetQuestions9-Aug-10 20:08

I was reading about

1. WMI and WMI providers
2. Filewatcher class in DotNet

I have a question.

I I should be able to a DotNet application that uses filewatcher class to track changes
to a file name (rename).

I would like to to have my tracking application running all the time.

I want my tracking application to make use of WMI concept to generate a 'peep ... peep'
sound when a file is renamed.

Is this feasible.

That I need WMI is a guess.

Or is it that to do this I do not have to use filewatcher at all and I just need the WMI?

You need to handle the Renaming event of the FileSystemWatcher and use SoundPlayer class in it to play the sound.

Hi danish,

about using SoundPlayer class in it to play the sound

So there is no WMI here?

No you do not need to use WMI. There are already pre defined set of classes that can do the work.

P/Invoke "why" question

Gordon Kushner9-Aug-10 8:07

Gordon Kushner

9-Aug-10 8:07

Here is one for you Win32 experts. When I as a Framework developer need to use a Win API function, I can declare the function with parameters I need rather than with strict type checking.

For example, check out the underlined code in SendMessage()

<br />
[DllImport("user32.dll", CharSet = CharSet.Auto)]<br />
public static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);<br />

<br />
[DllImport("user32.dll", CharSet = CharSet.Auto)]<br />
public static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, StringBuilder lParam);<br />

StringBuilder? Hello? What perplexes me is that the API is expecting a pointer but we pass in a .NET StringBuilder.

Please explain to a semi-newbie what dark magic allows this to happen.

Thank you.

Gordon

That one is pretty simple, at least on the surface: all the compiler does is check consistency between your calling code and the prototype(s) you provide (both in C# or VB.NET), as if the native method were a managed one (but with the implementation lacking).

The compiler never looks at the DLL file at all, it does not even have to be present while building. At run-time what gets passed is not type-checked at all, so whether it is an array pointer, a StringBuilder reference, or an IntPtr, as long as it points to the actual data, it could work.

FYI: there may be some data conversion going on behind the scene, e.g. when the data passed is a string and the native method uses ANSI (8-bit!), the "Marshaling" will convert to/from Unicode (16-bit) for you automaticaally (using a temporary buffer, so also faking the pointer value!).

Luc's given you a brilliant answer!

In my experience, anything that takes the same memory footprint can be used. This makes int/uint (4 bytes), or even long/Size (8 bytes) interchangable.

In the case of pointers, any reference type (or value type if used with ref [or out depending on the situation]) will work as it's the pointer to the object that's passed not the value pointed to.

Whether the value stored at the address can be understood on the native side or managed side once returned is another matter of course!

The .NET P/Invoke marshaller has special knowledge about some types.
For example when passing a String, it passes the pointer to the string data, not the pointer to the managed string object.
When passing a StringBuilder, the .NET marshaller passes a pointer to the StringBuilder's internal buffer.

Another useful idiom is the SafeHandle: you can create your own SafeHandle-derived class and directly use that in P/Invoke signatures. The .NET marshaller will pass the underlying handle (IntPtr) instead. This is extremely useful because it avoids a number of problems: for example the finalizer could run when there are no active references to your object, but the underlying handle is still being used in a P/Invoke call. Using a SafeHandle directly in the P/Invoke signature makes the GC aware that the handle is used during the lifetime of the P/Invoke call, and it'll avoid finalizing the object until the call is complete.

This is the voodoo that had me baffled the most. To the .NET developer, the StringBuilder is a sophisticated managed class, but somehow the API is able to treat is like a char* (I think).
