Hi
I have defined client class namely Client.cs and a server class Server.cs..Both the server and client are able to communicate...
I want the Client.cs to be called and executed with a button click event...I have defined Client.cs in a separate file in the same project..I think that it is not possible to call the class Client.cs....
How should i proceed with this?Please help me with this..
Thanks for any help in advance...

You can't call a class. You can call a static method on a class, or a normal method of an instance of the class.
You probably want to new up the class and call an entry point in it.

In your form(the one that contains the button), from the button click event handler, you may create an instance of Client, but make sure the Client class has the public modifier, and also include the namespace (if its not the same):
Client client = new Client();

Hello sir/madam
can any one help how to select an image from web randomly and store in another form.
For example:
when i type red rose in textbox i get a list of red roses in the listbox. This images are been retrieved from the web. Now my problem is to select randomly 10 images and store in another listbox.

The answer to this is google. Both for the images, and how to get them.
|
|
|
|
|
You may use the Random class to get random numbers. Use these numbers as indexes for your already created list, but make sure the random indexes are lower then images count.

I'm retrieving images from web in a listbox. I have to fillter the images that is been retrieved and store in another form.
|

If not even Google itlsef managed to determine the content of an image from the internet without the description, why do you think it should easy enough for you to do?
The best is to use Google mage search with the passed phrase (in this case "red rose"), then temporarily save a number of the pictures. (I don't know how to connect to google and retrieve images programmatically).
Next you calculate the random number and pick the 10 (or whatever number) images accordingly and throw the rest away.
Finally, you use PictureBoxes to display the kept images on your form.

I have no idea, as I really don't know what you are actually trying to achieve.
What is it that you are trying to do? And I mean at a higher level because you have obviously got your self stuck thinking at too low a level.

Do you mean you added a reference to an assembly in your project and it works okay through the Visual Studio web server, but not when you upload the site to IIS?
Also, how exactly does it "not function in [the] IIS server"? Does it give an error message?

What does that mean?

Hi,
Yes it throw error."Woking access to the dll is denied",something like this.My IIS pick the publish folder.hope I am clear.

If you get the exact error message you can do a search for it. As it is, "Woking" is a place in the south east of England near London.
Anyway, it sounds like a permissions problem. You have to ensure that all the files are accessible from the user account that your web application is running as. This will often be IUSR_.... But you can check that in IIS.

Hi All,
In MS SQL 2000, How can I check any row of database has updated or not through update query. My basic problem is that, same user has logged on two different system when they login at same time. I want to restrict the second user for login with same name.
Regards
|

The better option is to maintain a user session table and put an entry in it when user loggs in.. Then while logging in you can check whether that particular user id is already made an entry in the table and restrict accordingly. Remember to delete this entry on a session end or logoff

Thanks for reply,
I have already done thats a way which you are suggested. It works perfectally in normal situation but when I login same user in two different system at same time, then the problem occurs. Both the system executes query at same time and retrives the same result from database. Thats the area where problem occurs.

You can use the database transactions properly to lock and allow only one user/transaction at a time. So the first user who get the access could login and the later will not. Since already one entry is there.

Few questions:
- Are you using a single database (all connections go to the same database)?
- is the connection alive all the time the user is logged into the system?
