Does anyone know what the command line argument to launch a screensaver's options/configuration dialog is on Windows XP Pro?
From most of the example source code I can find on the web, it would seem to be '/c' but that does not seem to work for the screensaver I have written. I've tested my code and if '/c' is the first argument then the options dialog is launched but Windows XP does not seem to be supplying the '/c' argument when I right click on my .scr file and select the 'Configure' option from the menu.
After sticking an throw Exception call right at the start of my screensaver's main function, then running the 'Configure' option from the right click menu for the .scr file, then attaching my debugger to the screensaver when it throws the exception, it would appear NO arguments are being passed to the screensaver (args.length=0). I take
it this means that windows must try and launch the configuration dialog some other way? If so does anyone know what the other way is?
I'm the screensaver is written in C# and I am running Visual Studio .Net 2003 and Windows XP Pro. Does anyone know of any windows settings that could maybe be causing this?
Cheers,

After more web searching, I'm starting to suspect it might be a local windows setting causing the problem. I've also tried running the screensavers supplied with Windows XP (in ..\windows\system32\) with the /c command line option, this does open their configuration dialogs.
So I'm wondering what my app is missing to not pick up the option, although most of the C# demo screensavers I've tried still seem to get it wrong too...

I mean I have a class in C++ in a DLL with exported functions and of course constructor and destructor.
Can I link to this class from C# somehow? I just found a way to link global C functions.
What about C++ classes and methods?

Yes, search codeproject, msdn, or google for P/Invoke, aka platform invocation services. It allows managed code to call into unmanaged exported functions. While this was created primarily for calling into the Win32 API, it can be used on any C/C++ dll. Also have a look at P/Invoke.net.
Any remotely useful information on my blog will be removed immediately. There are 10 kinds of people in the world. Those who have heard of the ubiquitous, overused, worn-out-like-an-old-shoe binary "joke" and those who haven't.

Yeah. I found that before. But my question is how to call exported classes? Of methods of classes - not just global exported C/C++ functions.

Hi gurus,
I have two questions for you guys,
I would like to know how I can convert the contents of a string to a byte[] array?
Also, what is the equivalent of the >>> java operator in C#?
Thanks 
Best regards.

I'm writting some remote admin software in C#, I would like to be able to implement a remote desktop, much like what MS does with the windows terminal services, however, i'm too poor to pay for this, and hence want to write my own. Unfortunately, I'm not too sure where to start.
I'm intend implementing the solution on Win2k/WinXp. I have VNC connections to the destination networks, however, an HTTP connection solution would be optimally desired.
I currently can see one option available to me and it's not the optimum way. To use a screen grabbing process and download compressed images and mouse coords of the remote machines desktop to the server software, while coordinating keyboard/mouse input between the server & client software.
Using this method, a screen grab of 256 colours, 1024x768 resolution, zip compressed, the file size of the image is about 40-90 KB. With the bandwidth available to me, which is about a 500 Kb/s (62 KB/s) cable connection, the results are going to be slow frame rate of about 1-2 frame/s, which is not really acceptable.
If anyone can give me any pointers to source code or methods to implement a better way, it would be most helpful.

Take a look at the RealVNC protocol specification, that should give you some ideas.

The Load event of a Form lets you write code before/after the form is loaded (don't know for sure). The doc says "Occurs before a form is displayed for the first time.".
Question: Is there a way to do something after a form is displayed for the first time?
I want to do some lengthy processing and it would be cool to have the form visible before displaying a wait-window or a wait cursor. I already tried to handle the WM_SHOWWINDOW message, but unsuccessfully.
Maybe I could post myself a message with PostMessage (if it is available)?

Thanks for your feedback! Unfortunately it has the same effect es handling the Load event in my current scenario. (I.e. the result that the dialog is not shown before finishing my lengthy processing).
I'll keep searching...

Use activate and set a variable to true. It:
.... ACTIVATE ....
if (!_tastDone) { DoSomething(); _taskDone = true; }

How about having a timer on your form that fires a fraction of a second after the form is opened?

I am trying to automate MSExcel and have so far been unsuccessfull converting text to columns. Does anyone have an example using the excel texttocolumns method?
Thanks

One of the best pieces of advice... use the macro recorder !  Open the editor and its crystal clear how you can work with the object model to do C# code!

This is how I have gotten through most if the issues I have encountered, but I have been unable to convert the VBS to C# when it comes to converting text to columns
Thanks

I'm interfacing with the iTunes SDK and need to grab the "artwork". Writing these files to disk is quite easy as the SDK provides a method SaveArtworkToFile(string path) to write the file out to disk. I currently then turn around and read the image back in for use.
I'd really like to get around having to write out the file. Is there some way to "trick" the SDK into thinking it's writing the file to disk but instead write it to some kind of memory stream? Keep it mind that this is the only call made available to get the artwork and that it only accepts the path for writing out the file.
That's why I called it a "virtual file".

Then it that case, no there isn't. If there is no function to return a pointer to the image, you're pretty much limited to writing it to a temp file and reloading it in a more accessible form.

Yeah, I really guess I knew that. I was just hoping there was some arcane use of MemoryStream or some other mechanism that could give me what I need. That would be pretty cool if you could do that... somehow make that function think it's writing to disk when it's actually writing to memory.
