The DaysInMonth is a static method, so you use the class name to call it, not a variable instance:
DateTime.DaysInMonth(DaySel.Year, DaySel.Month)
I don't know the exact reason why you can call static methods using a variable instance in VB, but it's not very logical.
Despite everything, the person most likely to be fooling you next is yourself.

I have been using C# for 6 odd years, and never needed to even find out what that is used for. I suspect something to do with COM. Well, COM is dead!

For starters, have a look at the documentation how to Show a window (or control) Control.Show Method [^]. There's a simple example in doc.

UCOMIStream is needed when communicating with COM objects, if you need the communication in streams between managed code and COM-object you'll neeed the interface regardless of the language, but you would be better off not using COM objects unless it's a requirement.
The need to optimize rises from a bad design.

You d´ont want to do that. 
1) use mdi child/parent forms or
2) use usercontrol as pages, for that you will have to use delegates.
About second question i d´ont know nothing about that.

Not a technical question, rather a fairly nebulous question about a UI design.
In summary, I have an application that may or may not perform a task every minute. I need to create a visual representation of when this task will be performed over a day/week. Something like a time line where a user can view a single day/week that displays when the task will execute.
As an example, the task is configured to execute at 12,34,45,50,56 past the hour in the hours 1,4,8,15,18,20,21,22
The problem is that there are 2440 minutes in a day, so creating a visual UI is somewhat complicated. Unless of course the user has a 500 inch wide screen monitor 
Just incase anybody has heard of it, I am trying to create this for Crontab jobs.

Why don't you 'steal' MS Outlook's calendar view... I think it's a neat way to present events over time.

I don't know. There have been days when I've felt like there's an extra 1000 minutes in there.

Vogon Guard Well, the hours are good.
Ford They'd have to be.
Vogon guard But now you mention it, I suppose most of the actual minutes are pretty lousy.

There are several third party calendar controls available (free and licensed). I would pick up a nice looking and use that.
Some of those have even Gantt-like view just in case that you want to visualize the length and other information for the tasks some point in future.
I wouldn't believe that it has any effect on visualization if the task scheduling system is crontab. Only when getting the data into the calendar (or similar), you must implement your own 'parser' for crontab syntax (how to separate minutes, hours, days, what * means etc).

Hii
Can anyone tell me what's the exact difference between validating and validated events. What I know is validated occurs after successful execution of validating. But what's the need of 2 events I cant understand. plz help
if possible give code for illustration
thanx
|
|
|
|
|
One is an event you hook into when your object is validating, and the other is the event you hook into when your object has finished validation. You hook into the validating event if you want to perform some work when the validation is started off.

hello everyone..
please help me about this.
I have an application that requires cv loader... For example, I have a resume (in any format, txt or doc file), then when I upload it using c# or in any language and i need to get the name, address and contact number of the person that will be saved in an oracle database...
Is there someone who can give me some hint in creating this functionality
thanks in advance.

There's no foolproof way to accomplish this, but I'd suggest that you take a look at using IFilter. There are a couple of decent articles here on CP that will help.

i'll try it.

Please don't cross post. If your question isn't language specific, you should not post it in the language specific forums.

I have four select statement in 1 stored procedure, I will use it for 4 different dropdownlist.
SqlDataAdapter sqlda = new SqlDataAdapter("populatelist_sp", osql);
sqlda.Fill(DS);
<code>Cache.Add("listTables", DS, null, DateTime.Now.AddMinutes(60), TimeSpan.Zero, System.Web.Caching.CacheItemPriority.Normal, null);</code>
DropDownList1.DataSource = DS;
DropDownList1.DataBind();
The PROBLEM: When I used the cache object to populate another dropdownlist it gives me error "Object reference" meaning the value in the cache object is NULL. Out of 10 run I encounter 8 times.
if (DropDownList2.Items.Count == 0)
{
DataSet localDS = new DataSet();
localDS = (DataSet)Cache["listTables"];
DataView dv = new DataView(localDS.Tables[1]); --- Failed on this part
DropDownList2.DataSource = dv;
DropDownList2.DataBind();
}
Is there any settings that I need to do to retain the value inside the cache object?
GAIN: Instead of 4 roundtrip to the database in getting the value of the dropdownlist I only used 1 connection and the rest is Caching dependent.

You have not checked if the cache is still valid.

Are you sure the dataset have at least 2 tables, on every call?

Definitely yes, before assigning it to cache the Dataset (DS) has four tables, after assigning to cache object I can still see the 4 tables. But only after pressing the 2nd dropdownlist with postback where data should come from cache object instead of database the value of cache is null.

That is quite interesting. You not running out of memory for caching perhaps?

Nop. I just change the CACHE to ViewState Object and it work.
Though I believe Viewstate is not the solution since I have 10 dropdownlist in every page. Viewstate will make my page heavy becuase of the encrypted data.
I tried to search the Net and I can't find any solution to this problem
