Unless you can find an ADO.Net driver for SolidServer, you're stuck with ODBC. I did a quick search for it and didn't find anything. Mind you, I've never worked with SolidServer.
Depending on your application, you might just want to fire off a background thread to process the database update so the user doesn't sit and wait (the assumption being that it's a UI app update).

hello,
I'm dying here, trying to implement an ITemplate class. What I'm after is to dynamically build a listview itemtemplate with a number of labels. Has anyone managed to do this?
Best,

Hi,
I am having one content page, Menu on Masterpage and details on content page. Menu strings will be taken from database. Now what happens whenever I click any menu, automatically my master page get loaded and the menu string also taken from database. I don't want it to be taken up always from database, I need some way to preserve it in master page itself.
Any Luck.
Be simple and Be sample.

You should look into caching the data from the database. Take a look a the caching page directive. If you're referring to the page refresh, you could look into ajax to avoid unnecessary page refreshing.

Hi, I need to use a PropertyGrid to display various properties and allow the user to change the values.
The first problem is that I've never worked with a PropertyGrid before and after searching for tutorials and experimenting on my own, I still have no clue.
Almost all tutorials I found were about modified versions of the PropertyGrid that require you to already know how to use the standard version, which obviously doesn't help me.
The second problem is that at runtime I don't know anything about the attibutes.
I neither know the name, the type, the category, the description nor the value.
Is there a way to dynamically add a collection of properties to a PropertyGrid and have it determine the necessary attributes (such as category and name) at runtime?
Thanks in advance.

Megidolaon,
Just assign:
propertyGrid1.SelectedObject = theClassYouWantToView

It's not that simple.
I have a class called Task which has List of TaskParameter objects.
Each TaskParameter object has the properties "Name", "Type" and "Value".
"Name" should be displayed as the name of a property in the grid, "Type" I want to use to validate the user input and "Value" is the value of Parameter.
The amount of Parameters, their names, types, values, categories and description must be dynamiccally assignable because they change from Task to Task and the Tasks (the Tasks are also subject to change at runtime so I can't just create a different class for each Task).
Is there a way to create a class that allows me to dynamically assign names, types, values, categories and description (readonly and browsable are secondary, it's assumed all properties that are in the TaskParameter collection are browsable and assignable by the user) for a property at runtime and also displays a whole collection of them at once?
So far the only noteworthy results I had when using only a single TaskParameter object and when I used an array created from the TaskParameter List of the Task class, it only displays the "Name", "Type" and "Value" properties but without any descriptions, defaults or anything else.

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)?
BTW are you voting down Christian?

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.
sailesh_gupta wrote: 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.
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."

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
