Actually, you don't even need to parse a command line to start your app in a minimized state. just don't hard-code the Form.WindowState property and in the shortcut properties for your application, set the Run: setting to Minimized. You can also set this in the shortcut properties for an installer such as Windows Installer.

Anyone know of any components for writing CD's or DVD's in C# ? I presume there's no API's to do it in the language itself... I've found the MSDN one that does them in XP, but I want to be able to create video CD's, which this will not do.

Thanks - got that, but it doesn't do what I want. I edited my post to clarify, so I guess you didn't see it, but I added that what I want is to burn VCD's or movie DVD's.

I'd love to know exactly how DVD authoring works, but I don't think a lot of it is public information. I'd love to make a cheesy utility (cheesy in that it's not WYSIWYG GUI etc.) that took an XML file and created a proper DVD image.
If you find some good specs on DVD's let me know.
A decent place to start looking at all this stuff is doom 9.
I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf.

Christian,
Your post got me searching after work. I've wanted some good DVD authoring libraries for a while, and like I said in my other post, I'd love to be able to make something that simply used XML as input and created a DVD. It turns out, someone else is many steps ahead of me.
I found a pretty cool project on SourceForge. Take a look at this project. They've basically created a console application (Win32/*nix) that takes an XML file as input and generates a DVD. It relies on other console apps (it's very *nixy like that), but it appears to actually get the job done.
It's not exactly a library, but the source code is available and the application in general seems very ripe for automating.
I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf.

The VCD format allows one to place data on a disc without CRC checking thus u can fit a full 800mb on an 80min cd (like an audio cd). I have tried to make VCD's in the past, but with no luck though.

Seen on my Campus BBS: Linux is free...coz no-one wants to pay for it.

So in other words, just duplicating the file format of VCDs and burning them won't work ? Damn.
I've made heaps of VCD's that worked fine, just not programatically.

 Looking for some help on how to print a custome page size. What I have is a third party pdf creator which is set up as a print driver in which you select it just like a printer and then send it a print doc(document.print()).
The problem is that when you select the paper size it does not retain the selection and always goes back to the default size. From what I have read this is a know bug in .net and the only fix in win32 api's. I am not familiar with how to do win32 api call in .net and am looking for any help I might be able to get. Fairly new at this stuff so any code would help.

Hi. I'm a relative newbie with C#...I have some custom controls that are snarfed code from a co-worker (the only other C# code in our workplace).
I have created a windows control library project, added the code to it, and compiled it to the dll. Now I have gone to the custom controls and added them to the pane by selecting the dll file. But when I try to drag the control on to the form it gives me an error:
An exception occured while trying to create an instance of CTSSExp.Controls.ExplorerControl. The exception was "null" is not a valid value for 'control.'".
CTSSExp.Controls is the namespace the control is in and ExplorerControl is the name of the control.
Any suggestions?
Thanks.

yeah - try to avoid cut and paste coding, it leads to errors. Also, avoid the form designer, that's not programming, and the designer really screws with your aspx HTML, sometimes making it invalid and often making it unreadable.
You should put the custom control into a project and use it from that project in order to eliminate any errors, then try putting it into a dll. That way, you are establishing that it works one step at a time.

You are right about cut/paste coding...but in many work environments, its common practice.
However, I did put it in a sperate project (control library template) which compiles (no errors) to a dll.
I then add it to the form designer (add/remove and select the dll file), but when I try to get it after that (it shows up in custom controls tab on the toolbar) and drag it into the form I get that error I mentioned.
I'm sure its something simple...I'm just new to controls and still do not have a "lot" of experience with Visual Studio.Net and the .Net way of doing things.

In workplaces populated by idiots. Seriously, if you know it's bad practice, why do it ? Are you GUARENTEED to work in that place forever ? It's just self preservation to learn to do things the best way you can. If your workplace has components it wants reuses, they should be packaged in a dll to start with, and that project should be the only place the controls are modified, via source control.

So there are no compile time errors. I got that before. What does that have to do with run time ?
KingTermite wrote:

Like I said, don't. The form designer is the tool of idiots. Create a form, play with the designer, then go back to your HTML and see how much it has been screwed with.

Sure - that's why I suggested a couple of steps whereby you can elimanate some factors, and some bad practices, and figure out what the problem is.

No need to be so one-sided....we are not a workplace run by idiots...in fact we are at SEI level 5. Cut/Paste IS a level of reuse. It's called salvaged reuse. We do package "planned" reuse into a dll or other such libary, but my long term intentions are to modify and likely extend this control once I've got it working in the first place.
Now....what HTML are you talking about? I would skip the form designer if I knew how. I need to know how to put the control in if I'm going to do that. I was trying it from the form designer because I thought that was the proper method.
Thanks for trying to help...any more detailed info would be appreciated.

I never use the form designer either. I click on the tab at the bottom that says "HTML" and go from there. It does save a lot of headaches in the long run.

Any aspx page is has a .aspx file and a .cs file. The cs file is your code behind, the aspx file is your page, containing all your HTML, including the asp: tags that denote controls. When you're in the form designer, at the bottom of the page is a 'html' tab, if you click on it, you can hand edit the files. This is definately the way to go, and you should set up your preferences to always go here instead of the designer, for the reasons I mentioned.
And if it were me, I'd create a new control in a project, then copy and paste the html and C# code into it, then change the namespace of the class to match the project, and try to use the control in a page. Unless it's a server control, that's just a cs file, but I'd do the same with that. Not least is the fact that you could then set break points and step through the constructors, etc. to figure out what is going wrong.

I'll look into what you guys are talking about. Right now I don't see it...I don't see an HTML tab and there are not aspx file (there are some resx files though...maybe that's it?).
Anyway...I think I figured out my problem. There are two controls that I ported (with the exception of using the form designer, I did it exactly as you described for me to do it, Christian). The control that I kept trying (thinking they were all basic controls) was actually a control that contained another control or two within it...since there was nothing there, it was throwing the null exception.
I tried the other control (name didn't sound right to me for what I wanted), but actually turned out to be the control I wanted and was a basic control thus yielded no errors.

Glad it worked out, I've worked out something too. I'm in the C# forum, not the ASP.NET forum. You therefore are probably working on a GUI app and you have no aspx files, no HTML. Sorry, my bad.
Just out of curiosity, is this app for internal use only ? If not, why are you using C#, does your target audience all have the .NET runtime, or will you only distribute on CD, or do you consider the business lost to people unwilling to download the runtime to be negligible ?

Yes, its a C# app....I guess that is why no aspx files.

This will be an internally used app, so distributing the .Net runtime will not be an issue in this case. If the computers don't already have it, the runtime will be included with the install eventually.
Our company does primarily embedded software and test software for host computers to test that embedded software. So we don't have mass produced PC software....so that's never been an issue for us. We sell the entire test sets, computer and all....so if we develop something in .Net, then the software, framework and all will already be on the computer when it is sold to the customer as a "test set".
This allows us to develop, as long as customer has not dictated something special, in whatever environment/language we want (although 90% is currently in C/C++ right now). We have just a few groups that are trying to get a little more cutting edge and trying to bring some new technologies into the arena.

How can i use the ping utility in my program.
I need to ping a particular IP address and display the result.
|
|
|
|
|
There's two options:
1. Run the ping program by launching it. There's LOTS of examples out there on how to launch a console program and redirect its stdout and stderr back to you.
2. Figure out the ping protocol and write some socket code to do it yourself.
I'm guessing #2 wouldn't be that hard to do, but I've never looked at ping myself.

Written a GDI package; But now need to:
1.Develop Code which allows shape objects to be dragged (moved) and resized by implementing grab handles. Write a key handler such as when the delete key is pushed the shape dissapears.
Difficult as my shapes arnt saved in array!
2.Add advanced features such as current co-ordinate position of the mouse.
I think this would involve mouse_move and some text boxes
If you can help, i'll send you a zip of my project.

In order to do this, each shape will have to be an object so that you can individually manage it. In your MouseDown event, determine if a shape exists under the mouse and begin tracking that shape (perhaps a private field that represents the currently dragging shape). In the handler for MouseMove determine if the mouse is down and if an object is being dragged. If so, shift the coordinates of the object be dragged and call Refresh to invalidate your form and repaint those regions (it would actually be better to invalidate the region previously occupied to the whole form doesn't have to repaint). In your MouseUp handler set he new position of the shape and clear the field that tracks the currently dragging shape.
Miles Roberts wrote:

Actually, this is pretty easy. The MouseEventHandler passed to you in the handler for the MouseMove event contains the X and Y coordinates of the mouse in the coordinate space of the control that raised the event (such as a Form or Panel onto which you're painting your custom shapes). Just use those and display them in a StatusBar or something:
private void myForm_MouseMove(object sender, MouseEventArgs e)
{
this.statusBar.Text = string.Format("X={0}, Y={1}", e.X, e.Y);
}
