Problem with SetupProject

19-May-09 4:57

Hi,

this is a snippet I once used, it shows "User" or "User, Administrator" IIRC:

List<string> roles=new List<string>();
try {
    //  on LP9300 this code produces an exception "Unable to get role for this RID"
    Thread.GetDomain().SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
    WindowsPrincipal wp=new WindowsPrincipal(WindowsIdentity.GetCurrent());
    foreach(object roleName in Enum.GetValues(typeof(WindowsBuiltInRole)))
        if (wp.IsInRole((WindowsBuiltInRole)roleName)) roles.Add(roleName.ToString());
} catch (Exception exc) {
    log(exc);
}
log("Windows role = "+string.Join(", ", roles.ToArray()));

Hi,

I've added a setup project to my solution and added the project output from a windows App. The install worked fine.

I then changed 2 settings in my config file from User settings to Application settings. Rebuilt the projects and tried to re-install. The config file did not get updated in the installed version. I'm using vs2008.

I even tried removing the setup project and creating a new one. But, the old config was still installed! How is the Setup Project still referencing the old config file? I click on the project output in the setup project and select "Outputs". This gives me the directory to the config file. I've checked this and it does point to the correct version of the config file. So I'm confused as to why the config file isn't changing.

Any ideas?

Thanks.

Sorry for replying to my own post.

I've tried this again in anther solution. Just added a Win App and a setup project to the solution. I added some Application settings to the app.config file and installed. Then Changed the Application settings to User Settings and re-installed. The config did change on the second install so now I am really confused.

The only thing that I can see that I am doing differently in my main solution is Changing the Assembly Version number. Would this affect the Config File not being correctly installed when using the Setup Project?

Hi,

I know I'm not getting much input on this but I've just deleted the Setup project and added again but with a different Project name and this worked. This has got me over the problem short term but I'm worried what will happen when I need to upgrade my project.

Last attempt but has anyone got any ideas? I've tried changing the version number of the setup project and setting "RemovePreviousVersion" to true but everything I tried just didn't work.

Static class info across multiple application instances?

If I change a static class variable in one application instance and I have multiple instantiated applications using the same dll will I be able to see that specific modification from one of my other applications? I'm thinking yes but I'd like to know for a fact. Any words of wisdom?

Thanx

No. Instance data as well as static data only exists inside a single process. In order to share data amongst applications, you must take special steps and use one of many available mechanisms, e.g. memory-mapped files.

Can you maybe elaborate on these mechanisms?

Re: Static class info across multiple application instances?

There are lots of mechanisms; whatever your need may be, a few of them will fit well.
Search for "interprocess communication", and read the documentation, there is plenty of it.

This isn't fully correct...
there is a method.. not for the feint of heart..

you can go into the .prj (or.sln) file and make a manual reference to the
location of the dll that you compile from the static class
(for each project that you want to reference that particular dll)

I've never done it (needed to do it) myself but I've heard about it...

come to think of it you can basically do this by add>existing project> your_dll.sln

then whenever you modify your_dll.sln it will be compiled into your other programs..

did I ramble.. sorry.

you can add the same code to several processes, that does not magically make them share some data; unless the code you are sharing is taking care of interprocess communication, but then you don't need a DLL for that.

Remoting the static instance is an option. Remoting offers out of the box support for singletons.

Without more information as to what your code is doing to make it draw black, I really can't say...

ok well here is the code.

Office 2007 Button[^]
i was trying to combine the two and it works half :}

and this is the code i have.

hmm its a bit to long to post here... but here is the draw

internal void onDrawControl(Graphics e)
{
recBounds = this.ClientRectangle;

this.Width, this.Height / 2);

for (int i = 0; i <= 40; i++)

e.FillRectangle(myLinearGradientBrush, 1, this.Height / 2,
this.Width - 2, this.Height / 2 - 1);//down

I just tested it using the original code and just replace the method onDrawControl with yours, it works also fine...

Event Handlers

I have created my own class names Box.cs. Now I want to borrow the mouse Event which I see in most controls found in .Net and apply it also to my box so that If I click my box an event is triggered

OriginalGriff19-May-09 0:56

OriginalGriff

19-May-09 0:56

Which mouse event do you want to handle? There are loads: Mouse Down, Mouse up, Mouse move, ...
Is your class visible (ie derived from a form, or other control? If not, then it doesn't get mouse events!

More details, please!

just the Mouse Click event... Note that my Box.cs is a class that never inherited any object.

OriginalGriff19-May-09 2:00

OriginalGriff

19-May-09 2:00

A simple class:

class Box
   {
   ...
   }

is not visible on screen. If it isn't visible, you can't click the mouse on it. Your class should inherit from a form, or control (panel, button, textbox, label) that can be visible. You can then add events to it.

Just creating a class is not enough!
