Store your error messages in a database, and read them from there. I wouldn't recommend using resource files for this because it would mean that you have to do a different deploy between the environments.

Hi,
I am working on a project which involves controling the mediaelement to play videos from the server side. So far, I have no idea at all. I will be grateful if someone can give me a hint. I use visual studio C# as the development tool.

You need to look into streaming the video. As you haven't said what your client actually is, I can't be any more specific than that - but you now know that one of the keywords to search for in Google is "streaming".

Thanks so much. I really appreciate you answer.I have learnt something. As I am a newcomer to programming, I think I didn't make my question clear. Actually, I want to make two applications. The first one act as a server which can send a command via the Internet to the second one to request it to play a video. The second application is nothing more than a video player with embeded video files. My question is how do I write a programme which can send a command to the other application to request it to play a video.

If I were you, I'd look into using Windows Communication Foundation (WCF). This technology is designed to let you write code that can communicate using different transports (HTTP, TCP, etc), with the same code.

hi guys. i'm really need this .
i have a datagridview with 5 columns . i just attached my datagridview to my table in my access database what i want to do is to convert the first column from string to int , bcz it's saving as string in database and not as int .
the problem is when i hit the column header to sort the data grid viye by the first column is sorting like this .
11
1
2
55
6
7
8
but i want to sort it like this 1-2-6-7-8-11-55
.i think it bcz of the string format of the column do you know any way to convert the column . i think it should be fix if i convert the column from string to int or maybe it'll solve in other way .

I think (its been a while since I did winforms) you should probably change the underlying data collection. possibly do the conversion way back in the SQL query (assumption).

im sorry , but dont you mean to changing the value type of the column in access database or do sth else ?
|

|

Could you please not use text speak in questions? It makes it very hard for those of us who don't use it to translate it into English.
What he's talking about is transforming the type in your query - not in the database, but why would you want to store an integer value in a string anyway? Is there a reason you are doing this?
|
|
|
|
|
You have a couple of choices, convert the data type in your select query or add another column either in your query or the data table resulting from the query and populate the new column with the integer value.
And as POH said don't use text speak when you are using a computer!

Can we have a parametrised constructor in a static class?
|
|
|
|
|
Basically no. Static classes cannot have public constructors (any access modifier i.e public or private, in fact), and static constructors cannot have parameters.
Hope this helps

No. How would you call it? Static constructors are called by the framework at a time which your code can't know*, and without any parameters. In fact the same construct in Java makes this clearer by just being
static {
}
... so it doesn't look like a callable method (which it isn't).
(*: It's called the first time the class is fully loaded, which I think happens when a method/field/property is called. However, you still don't know when that is because some other code might use the same class.)
If you want to preload state then you can have a parameter-accepting normal static method which you call in the Main procedure or via a static constructor elsewhere. (Obviously, you could call it from anywhere, but you want to call it before you are going to use the class at all, and Main is about the only place you can guarantee that.)

|
|
No. Is that a homework question or is there a problem you're trying to solve? If the latter, what are you trying to solve?

We can have a constrictor in a static class (thought not a parameterized one).
Read more about this here[^].

Does that narrow the scope of variables?

No. Think about it. You need to have the static initialized when an instance of a class is created.

What error are you getting ?

Null Reference Exception?
When you select a different value in a ComboBox, the previous element gets de-selected, causing a SelectedIndexChanged event. Now, nothing is selected, the SelectedIndex is -1. Next, the element you selected gets selected, causing the next SelectedIndexChanged event. And now it is really selected, and you can use it.

Thank you very much  ...

Is this a custom built? I do not want to use custom built. I did one myself using Active directory directory service reference and the company do not want it.
Thank you,
Sai
