Complex rotation always has wrong answer. It looks bug is the visual Studio 8.0. Here is the code. - C# Discussion Boards

Hi
I'm using CodeDom and I want it to generate code such as the following:

if (var is MyClass)
{            
    //Do stuff
}

The code I am currently using to perform the generation is

CodeConditionStatement ifStatement = new CodeConditionStatement();
ifStatement.Condition = new CodeBinaryOperatorExpression(lhs,
                CodeBinaryOperatorType.IdentityEquality, rhs);

this code will generate the below statement

if (var == MyClass)
{            
    //Do stuff
}

All that needs to change is the ==, which needs to change to 'is'. Is this possible to do in CodeDom?

Also note that 'var' can also be a child class of MyClass (which is why I did not use var.GetType() == typeof(MyClass))

thanks

danielk_,

Dunno, why don't you type it and see what happens? Would be a lot quicker than waiting for an answer...

Regards,
Gareth.

AFAIK it's impossible to generate 'is' using CodeDom. You can try to use typeof(MyClass).IsInstanceOfType(var).

looks good. IsInstanceOfType should do the job
thanks

hi is that anyWay to save html pages to database fully (with all images,styles,...) and retrieve & display it when we request it ?
thanks

Sure. You need to be able to store a zip or an arbitrary number of files, as you will have no idea how many images there will be.

no i don't make zip file, i want to search in it via FTS (full text search) or use Regular Expression in html text.

Press x-axis it (rotates around x-axis looks OK) // Button
Press y-axis it (rotates around y-axis looks OK) // button
Press z-axis it (rotates around z-axis looks OK) // Button
Press x-axis it (rotates around x-axis looks Bad) it is rotating on z-axis, Now you cannot predict how this is going to rotate it.
I checked the angles and I was unable to setValue in any sense. Please look the code.

When you rotate an object, all the axis move. So, when you rotate around the X again, the X is not where it was.

Dear Christian Graus:
Forgive me my ignorance; I am rotating only one axis Not all (As I see it) . I think change is very small in code. Is this possible for you to guide me how to fix this problem? I would like to rotate only on desire axis about 90 degree from previous location. You help will be very much appreciated. It is blocking issue for me.

how to make a Bitmap object to copy from g?

There are many articles on doing screenshots, but I thought controls had a general method you could call that draws them onto a graphics object you provide.

hello
i want to get forms list in the solution of another solution.
i found that maybe i can do it by Reflection namespace but i dont know how!
plz help me.
thanks.

Yes, if you can do it at all, it will be via reflection. But, I doubt you can iterate over the classes of another running process ( is that what you're saying ). Can you even be sure it's a .NET project ?

hello. i have 2 .net project. i want to access form's name of first poroject in second project . i want to definite authentication and authorize of users to that forms.

if you have beter idea, plz help me.

laleh.rajabi,

All you need to do is add a reference to the dll in your project. Right click on References -> Add Reference-> your dll

Regards,
Gareth.

Solution or assemblies?

If what you mean is assemblies(dlls & exe), you can get the list of classes via reflection, then look at the base class name for forms. If the form's base class is an inherited form, look for the inherited form class name.

By world time i mean a time of a server or anything, NOT THE COMPUTER'S TIME, it could be the Greenwich time or anything but i want it to be the same in any computer i log in.
thanks.

There are webservices around that do this. You're going to end up with the time on SOME computer, somewhere. But, one would assume it was going to be correct.

Hi Guy

.NET offer this features for us.

You can directlly Universal time man

DateTime d=DateTime.Now.ToUniversalTime();

more see here

How does that help ? He wants to sychronise time between PCs, DateTime.Now is not going to do that, no matter what time zone he converts it to.

Mr Christian Graus

OK Cool

don't worry, yahoo offer a url for time sync.

we can get time in long , after we want to add that with our datetime object.

thanks for ur help.
