I'm working on an events page that presents a list of events and when an event is selected the details of the event are presented on another page. The event details page is querying the details of the event from an SQL DB field. I'm writing the details with response.write and since its all wrote with html tags its presents properly. The issue I am having is when I throw a function into the field text string and attempt to write it, I just get the string.
SQL DB field contains something like the below
<h1>Event Name</h1><p>Details</p><% PRESENTMEMBERS(); %>
Is it possible to execute <% PRESENTMEMBERS(); %> via response.write or some other method?

I have setup a DataSet with DataTables in a separate project in which I inialize and load it separately.
public class DataSetA
{
public Trial trial;
public DataSetA()
{
this.trial = new Trial();
}
}
Then when I wish to access the data in another class I use the following I get the following error message "Object reference not set to an instance of an object."
public static class Test
{
public static DataSetA dsA;
static void GetData()
{
Int32 nData = Trial[nRow].nData()
}
}
Can I do the above or do I need to load the DataSet through the constructor as follows.
public class Test
{
public DataSetA dsA;
public Test(DataSetA dsA)
{
dsA = new DataSetA()
}
void GetData()
{
Int32 nData = Trial[nRow].nData()
}
}
If it is a static class I can not do the above.
If alternative methods when do I use the necessary methods.

I appreciate any help you can give me.
Thanks in advance,
Michael

Hello Everyone,
How to generate 2 digit numbers randomly in every 20 minutes and save that numbers into database in every interval also.....
How to achieve this? Can anyone give me a solution soon.
Thanks

we don't provide "solutions", what we do is answer specific questions.
So what is your problem? what have you done? where are you stuck?

Hi
I have asked some idea to achieve this...
Actually I have to show 2 digit numbers at every 20 minutes in front end and save the numbers into database also. Eg: Show 6 different numbers at 10:00AM and save it, nest show another 6 different numbers at 10:20Am and save it, next......to till 8:00PM.
Thanks

and I don't see the problem here, it takes a timer, a random number generator, and some elementary database operations. What have you tried so far?

What they are trying to find out is what you have achieved so far. You have simply restated your requirements in a different format without showing what you have achieved so far - without this vital piece of information, it's difficult to assist you with the code because we could end up offering you advice that conflicts with whatever code you have in place right now.
More importantly, Code Project is not a place to come to have your code written for you; if you have some code and don't know or how why it's not working, or you have a query around an algorithm that you mostly have working, that's when the forums really come into their own. If you have shown no indication of the code in the first place, you'll end up getting short shrift I'm afraid.

How to convert variable name to string?
class SomeClass
{
public int SomeVariable;
};
string className = typeof(SomeClass).Name;

If you are using .NET 3 or above, you can use an expression tree to accomplish this. Here's an example of retrieving the field -
private static FieldInfo GetFieldInfo<T>(Expression<Func<T>> field)
{
FieldInfo fi = (field.Body as MemberExpression).Member as FieldInfo;
if (fi == null)
throw new ArgumentException("The field parameter should point to a valid field");
return fi;
}

That little snippet deserves T&T status.

Can't be done in general as:
- Values don't have names;
- Most objects don't have names (major exception is WinForm Controls, they have a Name property which is heavily used by Visual Designer);
- Variables have a name, obviously, inside the source file; the information is not preserved when compilation finishes. That is why Reflector uses mock names for everything that is a local variable.
Hoowever data members such as your SomeVariable do have meta-data inside the class, so you can use reflection to enumerate them, or obtain the value of a variable whose name you know at run-time.

is just silly.
Less typing is required to do string className = "SomeVariable";
I suggest you describe the real problem you are trying to solve, not a detail along the wrong path you seem to have chosen; and/or read up on reflection.

It is in the question, given class variable as input convert it to string:
string name = FieldToString(SomeClass.SomeVariable);

Use reflection. I.e. PropertyInfo.Name for the variable names.

Hi
In my application I allow for users to upload documents to a server via a web service. I recently created a progress form to show the progress of the documents being uploaded by incrementing a progressbar and updating some labels. However, the progress bar increments are equal to the size of the current document, so it updates in blocks. Is there any way to get the current byte or kilobyte being uploaded and increment the progress bar with that to create a better looking progress bar that continuously updates?
|

if you upload by sending chunks of data, then yes you could use the exact number of bytes transferred so far.
OTOH if your upload is a single action with no progress reporting, then you don't really know; you could still use a timer to have the progress bar advance corresponding to the amount of bytes in that upload, based on an assumed upload rate, which you could derive from the uploads done before, so only the first upload would have a jerky progress, and even that could be remedied by starting with either a historic upload rate, or a reasonable first estimate.
So it all depends on how you upload things. Since you asked, I expect you'd be in the latter category.
