conversion and porting bouli18-Dec-04 7:41 bouli 18-Dec-04 7:41  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. There is no spoon.

Alex Korchemniy Remote Desktop Craigjw18-Dec-04 4:37 Craigjw 18-Dec-04 4:37  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.

Uwe Keim18-Dec-04 3:48 Uwe Keim 18-Dec-04 3:48  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)? -- Affordable Windows-based CMS: www.zeta-producer.com Re: WinForms: Doing something AFTER a Form is displayed for the first time? leppie18-Dec-04 5:41 leppie 18-Dec-04 5:41  This what i normally do: protected override void OnLoad(EventArgs e) { base.OnLoad(e); // do stuff now, or just fire of stuff to ThreadPool } top secret Download xacc-ide 0.0.3 now!

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).

Matt Philmon17-Dec-04 12:10 Matt Philmon 17-Dec-04 12:10  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.

Matt Philmon17-Dec-04 16:15 Matt Philmon 17-Dec-04 16:15  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. Re: Not sure what to call it... virtual file possible?

You could use a memory-mapped file (read the MapViewOfFile API call documentation for this). But it is really overkill. Yes, even I am blogging now!

Alex Korchemniy Exceptions in windows forms problem Member 9617-Dec-04 8:24 Member 96 17-Dec-04 8:24  I am seeing an unusual problem, I have a main windows form that opens a form using showdialog. If there is an exception in that "subform" during a debug run the IDE shows it as being in the main form and if I break it breaks at the ShowDialog in the main form and not at the actual code that caused the exception in the sub form. I don't see this in any other projects, any ideas? Could it be a project setting somewhere gone awry or...?
