You should use Matrix transforms to rotate the drawing "canvas".

Deployment to Quick Launch Toolbar

I've developed an application and would like as part of the setup to place an Icon on the Desktop and the Quick Launch toolbar.

Ideally, I'd like to ask the client if they would like this to be done.

Thanks,

You just need to create a shortcut to your application's EXE in the directories designated for quick launch and desktop shortcuts

\Documents and Settings\username\Application Data\Microsoft\Internet Explorer\Quick Launch
and,
\Documents and Settings\username\Application Data\Desktop

where username is the name of the current user

Thanks alot.

I did a search for th quicklaunch folder but it I could'nt find it. You set me on the correct path.

I had the Desktop nailed and will probably use "all users".

This all being said, how do you create these two short cuts within the setup routine????

Thanks,

If you use the Windows Installer projects to deploy your application, open the file system editor view, right-click on the root folder ("File System on Target Machine") and add the "User's Desktop" (if not there already) ad "User's Application Data". To the latter folder, add sub-directories like Microsoft\Internet Explorer\Quick Launch".

Now, here's the trick. You'll need to compile the package and use something like Orca - an MSI package editor from the Windows Installer SDK - to go the Property table and create a new property called "ALLUSERS" and set the value to 2. You can't really do this in VS.NET's installer project because it frankly stinks. This is a cinche in professional packages like those from Wise Solutions[^] and Install Shield[^].

Thank you.

You know for something as common as asking a user "Do you want a shortcut on your quick launch toolbar" and/or "Do you want a shortcut placed on your desktop" and then have them check the appropriate checkboxes should not be so difficult.

Since I own the community that this applications is going to be distributed to, I don't have to ask the questions.

I've downloaded Orca and will give it a whirl.

I've googled this to death and there isn't much out there.

Thanks again.

It's not difficult if you use the right tools. VS.NET is meant to be a simple deployment solution. If one is knowledgable about Windows Installer (I've been using it since 1.0 beta days and even beta test it for Microsoft) you can use tools like Orca. There's also commercial tools out there that make these sort of things easy. VS.NET is not a viable solution for anything other than installing files and running custom actions written in .NET using the Installer class (perhaps a few other things, though not much).

I already provided links to two of the most well-known commerical tools for Windows Installer packages in this thread, sorted in order of my personal preference and cost (ISFWI is WAY too expensive and slow to support features unlike Wise).

Full Screen / Change Reso?

Actually, get rid of "Application Data" here. It's just \Documents and Settings\username\Desktop.

Hello everyone.

I'm new to C#, and not all that skilled in C++(only 1 semester). I am however decent in VB.

Anyway, I'm wondering if you could tell me how to, on startup, change the screen resolution and maximize my app fullscreen. My form is 1024x768 and I want it to fill the screen regardless of desktop reso.

This is just a simple game I am creating while learning the language a bit. This info would be greatly appreciated! Have a good day.

Set the FormBorderStyle to None, and maximize your form. When you do this, all appbars, including the taskbar, get a notification that a full-screen app wants the whole screen, so they run and hide.

Don't forget, that's

Hey, thanks for the reply.

I'm currently doing that. What I am wanting to do is actually change the resolution to 1024x768 while the game(app) is running, and then release it back to the desktop defined resolution upon exit.

This is just a simple project while i learn the language, but I would like to keep things simple in that respect and have it change to that reso when I load it. Any ideas, comments, suggestions and/or flames appreciated. Smile | :)

Thanks,
Acidon

Handling a car in a 2d game

Perfect. Thank you very much.

I did search for this type of info but never found anything. I obviously didn't use the right keywords. At any rate, I appreciate the reply. Take care,

Hey

I am trying to make a simple 2d racing game, the wiev is like GTA.

I have som problem with the car handling. I am using this math right now,

double radians;
double tan;

radians = this.Rotation * (Math.PI/180);
tan = Math.Tan(radians);

Position.X = this.CarBox.Location.X + this.Speed;
Position.Y = this.CarBox.Location.Y + (int)(this.Speed * tan);

this.CarBox.Location = Position;

The speed is between 0-20 and the rotation is 0-360 degree.

The car is now driving forward, when im turning the car rotates like it shild and it moves in other direction, but if i turn to much toward 0 degree(UP) och 180(down) then it will flip and disipare from the screan, the y value is then somthing around -32000.

I have also notis that if i drive in around 45 degreee angle it will drive a bit faster hen if i drive forward(right).

Im not that good at math so i hope somone could help me with this.

Best regards
Jimmy

lol no, what are you doing here? Math.Pi is 180 deg in radians! Smile | :)

[edit] my bad, the code was just lookign a bit confusing, why are you using degrees at all?[edit]

Thats what you get at the tan graph asimptotes. At pi intervals IIRC (i really should RC). Hence you can deduce that your angle plotting is not correct.

R_t² = R_x² + R_y² , pythagoras. And the resultant (R_t) should be a factor of your time/speed variable.

plot it on a piece of paper and it should all make sense Smile | :)

What is the best way to specify a directory in an application. The last thing I want is for the application to crash if it is not installed in the directory that is hard coded. I have certain files that I need to read from to setup my App. How can I specify something like [ProgramFilesFolder] in my app to look there for the necessary file. I know this kind of thing is possible with Windows installer projects. What about the App... especially since I'm still writing in debug mode. Once I add the installer, the files will all be moved to a different directory.

thanks in advance

Use current directory, and make sure u set your apps working folder to that Smile | :)
