In Windows, GDI+ can draw on a surface (window, bitmap etc). But a window cannot redraw itself (to draw another blinking state) after some time without using timer!
You can also create a c# control that will redraw itself with timer. It won't do any mess in your app, and will work great! That depends on what kind of blibking element do you need.

One not so obvious thought would be if a animated GIF and Picturebox control would work for your situation. It is not direct GDI+ but does allow for animation (blinking if desired).

We can see the items like data connections and servers in server explorer.Is
is possible to add our own items in Server explorer.So that we can launch
any exe or some action by clicking on that item.

I want to make a software that will be enable to run a script to generate action.
I will make a sort of dialog designer and I want the user to be able to add action on control but using a script That i'll make.
How can I do this ?
Source and explanation will be welcome
Thanks

You can use VSA. There is an article about it somewhere on CP.

yeah But VSA is not only for .NET languages ?
ME I want to make my own script language using C# but the user can Add a function call AddFile(param1,param2) and then me I have already declare the function in C# to make action for AddFile
Anyway I will try to read more about VSA.
Thanks a lot

Hi,
does anybody knows how to use list controls in virtual mode with C#? 
In unmanaged C++ this is done by setting the LVS_OWNERDATA style and
handling the according notifications.
Thanks in advance

Hi!
I think you can put your worker Thread function in a seperate class. Then you can initialize your class any way you like (with your "parameters") and set the ThreadStart delegate of your thread to the appropriate method in your class.

hello everyone,
i'm not sure if this is the right area but here goes. i've been tasked to create a web-site in c# that does several data related things, but the most important section is this part they call "the data import tool" ( yeah real catchy.. ) any whoo.. the idea behind this piece is the user would be able to create datasources that are basically just like ODBC DSN's, in that you select a type and depending on the type you fill out some info (i.e. ip address, login name, database name). this connection will allow the main site to take a search term and query across these different datasources. my question is, is this even possible? then if it is can it be done with c#. i've posted a quick sketch of what they are looking for at this address : http://www27.brinkster.com/jtucker/data.htm
any ideas, or help would be great.. thanks,

hi,
i'm writing a dll and there's a huge but constant data structure that is used from time to time inside the library.
when i put it into an ordinary class, this data-structure (it's a tree) has to be rebuilt everytime an object of the class is constructed.
there's no main-function or app-object to keep the tree reference throughout the use of the dll. reference lost, garbage-collector feeded 
what's the most effective way to solve this?
:wq

Hi
Have tried putting it in a different class and exposed it a static member?
You dont so whether u make changes to it, or it just serves as a "lookup table"...
Maybe it helps

yes it is kind of a lookup-table (a lookup-tree if you like)
but when i have that thing a static member of a class, it still has to be created once. when should i do that? in the constructor? but then the procedure takes place each time an object of this class is created via new. or do you think an additional static bool set to true after the first creation may help?
lets say
Class A { <br />
static Tree lookupTree; <br />
static bool created=false; <br />
A()<br />
{<br />
if (!created) <br />
{<br />
ExpensiveTreeCreationFunction();<br />
created = true;<br />
}<br />
}<br />
...<br />
}
and then i can use
<br />
A control = new A();<br />
A.foo();
as often as i like without ExpensiveTreeCreationFunction(); called each time? 
:wq

yes ! almost, but it would be better to check when calling foo() instead of a static constructor (some things never makes sense  ) or just add a static method to create it...there are many choices Do whats best for you.

checking in foo() is ok. i just tried and it seems to work.
to get things clear: when a class consists of a static member, this member is stored somewhere else than the objects of that class (which are destroyed by the GC when references go to zero) and are freed/destroyed when? at the end of the program-run? i just want to understand that...
:wq

The best solution to this is to use a static member and static constructor. Create some class which has the static member of the type you are referring to. Then put hte build datastructure code in the static COnstructor. This way the table will only be built ont time and you odn't have to worry about when to build it. The static constructor will be called before anything in the class is accessed.

Hi all
Im painting alot of lines to a part of the screen at a very fast rate (100fps). Now I note in taskmanager that the PF (pagefault?) delta goes up to 10000 - 15000 when these drawing operations take place. Is this normal and what i also find is huge memory usage (normal 20mb ranging to 120mb). Is this just the GC taking its time to "kick" in?
Thanx in advance

hmm. i have a program which runs all day long and does some minor painting/threading/network-things every 5 minutes. i had very neat effects with it running in the background (top was a complete reboot of my win2k-machine) - from weird/interchanged icons over wrong repainting to ... well this reboot once.
i don't trust gdi+
(yes i released every resource)

OK problem solved , a Bitmap object was created every frame, i decided get graphics object from handle instead of getting it from a bitmap. Damn that doesnt work either, different problem.
OK, then I created Bitmap at constructor. Helps with memory issue, but still seeing about 5000 - 10000 PF (page file, not fault  ) delta. Is this at all bad in anyway?
Maybe its time to look at DirectDraw...

Hi!
Do you call Dispose() on the graphic objects when you don't need them anymore (end of function or end of loop)?? Because the garbage collector doesn't handle unmanaged resources (like GDI or file handles) and therefore only collects your classes (and with them the unmanaged resources) during idle time.
Cheers
