 How do I know the Width & Height of physical screen in millimeters ? if I don't use DllImport("gdi32.dll") & GetDeviceCaps(hDC.ToInt32(),HORZSIZE) , because it must know hDC first!
thank you very much !

Maybe SystemInformation is what you need.

thank you !! but How do I know the window's millimeters or inches ? because I want to creat a form in any monitor device get the same size.
( like C++ GetDeviceCaps(hDC, HORZSIZE) )

I have one 'exe' and one 'dll' and I want to provide debug swtiches via config files.
Do I need two config files? (ApplicationName.exe.config and ApplicationName.dll.config) or One is enough?

You will need one for the primary driver of the process. That would be the app.exe.config
|
|
|

I already did that. And I kept the config file (applicationname.exe.config) in Debug\bin directory along with the EXE and DLL's.
< ? xml version="1.0" encoding="utf-8" ? > <br />
< configuration ><br />
< system.diagnostics ><br />
< switches ><br />
< add name="MySwitch" value="1" / ><br />
< / switches ><br />
< / system.diagnostics ><br />
< / configuration >
Ignore the spaces.
And declared the switch in both EXE and DLL's in their classes.
private static BooleanSwitch DebugSwitch = new BooleanSwitch("MySwitch", "Debug Switch for Trace and Debug.");
Eventhough I enabled the switch in the config, switch is always disabled.
Did I miss any other settings?

Two things to try. First of all in your solution, do you have the exe set as startup or DLL as startup and then asking the DLL to run the exe? If the latter then you need to switch to the former. I think.
Also what is the syntax you are using to get the value in the config file? Can you put a break point and see what is coming through? Maybe its not even picking up your config. Since you said you put the code in both the DLL and the exe, and that it is always coming disabled, it just might mean you are not picking up the value from the config file at all. Try looping through all values in the config file. If you get something then it means that the config file is being accessed, just not your switch. Try to get it to work with the exe and then move to the DLL.
OK hang on. Something very strange happened. I just upgraded to VS .Net 2003. I was looking into my sample code to see if there was anything more I had to tell you. I ran my sample and somehow my config file vanished. It was there and now its not. Go figure. Let me reset it and get back to you. Damn!!!!

Exe is startup and calls the DLL.

I think so. It's just only switch I am testing.
Do I have to keep this config file in the Build Action for the project?
I am running VS.NET 2002.

Does anyone know of a decent UML tool designed to work well with C#/.NET? I've been looking for one for a while, with no real luck.
|
|
|
|

I've been looking for a good one for some time. I found one that looks good, but it requires Windows 2000 or above and I have only Windows 98. (Sorry, I don't even remember its name.)
Right now, I use ProxyDesigner[^].
Let me know if you find a good one.

I think, that you can use Microsoft Visio. There is plug-in to Vs.Net. But you need to download Visio SP (AFAIK).

You might want to take a look at Enterprise Architect from SparxSystems.
A co-worker of mine who is a UML/design guru and now the leading C# expert that I know, swears this tool is the best he's used. We have before always used Rational Rose...he claims this does everything Rational Rose does only better and for only about $150 (instead of a few thousand like Rose).
It does reverse engineer and produce skeleton code for C# among other languages. I have been so moved by his rants over the last 6 months or so, I've actually finall purchased it myelf, just last weekend. I haven't had time to play with it myself, yet though.
There are only 10 types of people in this world....those that understand binary, and those that do not.

so what was your final opinion of Enterprise Architect?

Hey All,
The first time in my life that I have ever had the use the line control, or what vb 6 considered the line control, but it's no longer included in the .net toolbox. I know that I can easily draw a line on a form using GDI+, but Im creating a prototype form that has no real functionality, and I already get in trouble for writing to much code in my prototypes. Does anyone know where it went? lol
Thanks,
Ryan

They removed it for some reason... I just use a lable control and set the height (or width) to 1 pixel. You are screwed though if you need a diagonal line.
I know I have seen some other line controls around here... Have a look in the articles...

You can use the DrawLine() method on System.Drawing.Graphics to draw lines.

Nope, but I wrote up a quick control for you, I haven't implemented everything, however it does do the job (even works with diagonal lines ) I am writing an article on this, but here is some code that you can compile into a quick control if you would like, hope this helps:

Can someone explain to me the lifetime of a static member variable? That is, in a singleton, one has a static member variable of the single instance and a static member function which returns a reference to that instance. How is it that, 1) the static member variable is maintained, 2) the static member variable is destroyed (GC in the CLR, but what about unmanaged languages)?
|
|
|
|

You will need to count the references created to it, and if none is needed anymore, the unmanaged resources can be released. By design a static member will instantiate whenever it is first accessed and will last the lifetime of the appdomain. There is no GC on those objects AFAIK.

Hey I was wondering- why don't software developers (desktop software) not just make the desktop application communicate with a web site every now and then, sending the user's IP address and registration key? That way if someone installed a pirated copy, the company would know. I never see any companies do that. Is there like a law against that or something? (As long as it's in the license agreement of course..)
Seems to me it would work. I mean you could still crack it and take all those calls out, but the users of the cracked version would be counting on the cracker to have done a perfect job. I dont think I would trust cracked software that much!

First, seems to me there are serious privacy implications here. This would probably require that you totally open up your communications protocol to ensure to users that you are not sending private data back. Just look at how much some people freak out over cookies.
Second, you would drive IT admins nuts. Besides the added bandwidth of the communications that is required, some admins watch their traffic very carefully and want to know what each an every port and message is for. All it would take would be one admin to see that the traffic was carrying a serial number and you would be shut down quick.
Third, this method is not really well suited for any disconnected users (laptop users that work offline) so you would have to consider them.
I go by the rule that the 'harder' a products security is the 'harder' someone will be willing to work to break it. Put in just enough to keep an honest man honest and take care of the rest through support agreements.

thanks, some good points there,
I should mention that the app I'm writing is like an ide for web developers, so offline it's no good anyway.
But besides, I'm not talking about the app *requiring* a net connection to work. I'm talking about something more passive. So, when you run it, it checks to see if you're online, and if you are, it rolls some dice, and then decides to send the http get request (and doesn't even listen for response). Not only would the request be incredibly small- we're talking like the size of this sentence, its just the key I'd be sending, but it would also be infrequent. So, as for the "added bandwidth" I mean this codeproject.com page you're looking at is as big as like 400 of those little requests, which would only get sent like once a week per user. See what I mean?
The communication protocol would just be HTTP. And as for IT admins watching packets- it would just be an HTTP request, not an open port on the user's machine or something. In fact, I could even send it though an IE webbrowser control. A serial number is like A23S-SWE12-FW42, which essentially looks just like a session argument- you know like amazon.com/a/something.cgi?s=S42G2-GR445D or something.
Not that I'd be sneaky tho- it'd be right there in the user agreement.
Like I say it can be cracked, sure. But if you download some pirated software you have to count on the cracker to have done a perfect job, it's a question of you trusting the anonymous, shady cracker out there, which I don't think most people will do. I mean, I sure wouldn't.
thanks
