Hi,
The PropertyGrid is a complex component. If you want to use it, I recommend you to dig in the various docs, howtos, blog posts, etc. The Microsoft PropertyGrid is not very flexible but it can be powerful when you know all the internals of the ComponentModel stuff. A good starting point is the "Microsoft PropertyGrid Resource List" (see signature).
If you still can't make it work, ask some detailed questions, one per particular issue (yours is a bit vague). About your last sentence, use the DescriptionAttribute and DefaultValueAttribute. If you need them to be dynamic, you will need to publish your properties with the help of a custom type descriptor and custom property descriptors.
At last if a 3rd party component is an option for you, Smart PropertyGrid.Net is a time saver to build dynamic contents.

hi ,
can any one help me out in selection of range.
for exmaple we have two list consisting of 1 to 10 each
from first list we have selected 3 and other 7
in the second transaction we cannot have a rane say from 2 to 5.
Also when we log off the application and log in again we should see that we do not interect the selected ranges. i have sql database for storage application and developing application on c#.net.
pls help urgent

I can't follow the logic of what you want. Why can't you go from 2-5, how does that relate to 3 and 7 ?

select x = a if x falls in the range 3-7
then its illogical to have select x=b if x falls in range 2-5
coz in such case x would satisfy both the condition.

So what you really mean is that your second selection and your first can't be the same value ?
2 is not in the range 3-7

what i mean that no two selection range should intersect each other.
for eg:- range is 3-5
5-7
and not like
2-5
3-6
coz the value four falls in both the selection which is not possible

Well this is partitioning a (discrete) interval in not intersecting intervals. What is your trouble about (please detail)?

the problem statement is
i have two combo box's named max and min and a text box for entering value.
in max we have values range from 0 - 10
and similarliy we have in min.
now user has to select range from both the combo box.
like he can select min to be 4 and max to be 7 and value for this range to be some X%.
Now i have to restrcit user from selecting min to be 2 and max to be 6.
When the user closes the application and restarts it we should see that the above condition entered before logging off is validated before entering the new ranges.
i have sql database and using a application is begn developed using .NET C#

OK. that's fine.
sailesh_gupta wrote: n max we have values range from 0 - 10

That's good (possibly min should range 0-9 and max 1-10).
sailesh_gupta wrote: now user has to select range from both the combo box.
That is not clear. Do you mean:"The user has to define a range by selecting min and max values?"
sailesh_gupta wrote: Now i have to restrcit user from selecting min to be 2 and max to be 6.
Why? This point is very obscure.

Due to previous cluttered statements that is not clear.

That's an unbelieveble mistake. The reason you can't get help is all in your obscure descriptions.

yes you got it right.
also

i have to restrict the user from selecting the range between 2 to 6 because he has already selected a a range from 3 to 5.
which means
i should selectthe value of x = a if x lies between 3-5.this condition is set by user using the application.
during the next time user cannot put a condition that select x = b if x lies between 2to 6 beacuse already a condition exist.
i.e if both the constraint are there and input value is 4 what will be the value of x using the constarint.

Well, I think you need to re-design a bit your application. probably you need to let the user to define a set of classes partitioning the range.
For instance (Assuming adjacent interval classes):
Class min max assigned value
1 0 2 a
2 3 5 b
3 6 9 c
4 10 10 d
You can do that in several ways, neverthless a simple approach is the following:
the program starts with one default class
Class min max assigned value
1 0 10 a
The user may choose to split the interval by choosing the discriminator value, suppose 3, this will produce:
Class min max assigned value
1 0 3 a
2 4 10 b
and so on.
Note that user may only choose the descriminator (and class assigned value, i.e. a, b,...) properly rearranging intervals it is a program duty.
Hope that helps.

THANKS A LOT .... I GOT THE SOLUTION

OK - so how do the ranges get selected, by selecting a group from both drop downs ? I guess you can just check when the second range is selected, if it intersects. This seems trivial to me. Where is the issue ?

Hello everyone,
How to fix the compile error when interlock exchange a bool type variable?
public static void Main()
{
bool b = false;
bool a = Interlocked.Exchange(ref b, true);
return;
}
thanks in advance,
George

You're out of luck, MSDN[^] clearly says
"This method only supports reference types. There are overloads of the Exchange method for the value types Int32, Int64, IntPtr, Single, and Double, but there is no support for other value types."

Thanks Senthil,

Hey guys I'm new here! So here's my problem: I have to do a project for the university. I have to use a crawler, download some pages to my hard drive (number doesn't matter atm) and then for each page of these (for each URL to be exact) I need to populate a database with each page's URL and all the links that this page contains.
I found this crawler on the site http://www.codeproject.com/KB/IP/Crawler.aspx[^].
But since I'm a newbie I can't seem to find a way to do what I need. Do I need to html-parse each page after it is downloaded? Or can I simply tweak the crawler's code and do what I need?
Thanks in advance
George

Hi i have to develop an application which supports globalization feature. I am storing the data into a ms access database, so i want to know whether ms access do provide any features for globalization or not..

No, it's a database. You need to design tables that contain your globalised strings.

My program uses a lot of pictures (from screendumps) and I need to compress those so that my program uses less memory. Any idea how to do that in C#?

If you have an image as something other than a JPEG, load it into a Bitmap and save it as a JPEG.

Hi, i have a form which is size 500 * 300
I have groupbox, textboxes, and buttons inside that form. When the form is loading into my main mdi parent form, its size is 500*300, when i maximize the childform, my controls all are at the position top left. How do i make it center( when the window is maximize) depending on the screen size?
|
|
|
|
|
If you want to center the groupbox, not the controls in it,
personally I would recalc the Location from the groupbox on the maximize event.
The controls in the groupbox will change their location automatically.
For the other controls outside the groupbox, use a panel and calc its location as you do for the groupbox.
Hope this helps
