You say that like it's one simple method for every virus.

Sorry, it's not. Each virus has it's own cleaning method. This is because each virus either moves legitimate data/code to a known place (different for every virus), and if known can be put back, or just destroys the original data/code entirely, making cleaning impossible without restoring the file from a backup copy.

There is no "simple" method to catch packets. What you want to do is not an easy operation because it's tightly tied into the lower-level hardware of the NIC.

Hi,

We had developed our project into C#.net 2005,Now client is having project which is in Vb 6.0 and that project is using one another .exe file but that is lincesed but now he wants that to use our project's(C#.net).exe into vb 6.0.

my question is that if we replaced that .exe file ,is client need .net framework on his pc?becoz our .exe file is of C#.net.

2nd question.
Now suppose if we don't want to installed .net framework on client pc in that case can we change our .dll file (convert our project into .dll(class library)) and after using COM interoptiblity on that dll and then make the .exe file and replace with vb 6.0?

so can anybody tell me what is better & easy way to solve this?
can anybody tell me that what is min. requirement in client pc to use .net exe?

thanks.

Yes. Any piece of software developed in C# to run on a Windows platform requires the .NET Framework to be installed.

Web Service shared class definition

Hello,
I have two webservices that send/receive the same UserInfo class. How do I tell consumers that the UserInfo class is the same in both web services.

In other words:
[WebService(Namespace="thesamenamespace")]
public class web1 : System.Web.Services.WebService {
...
[WebMethod(Description="Update a user.")]
public void UpdateUser(UserInfo user) { }
}
[WebService(Namespace="thesamenamespace")]
public class web2 : System.Web.Services.WebService {
...
[WebMethod(Description="Get user.")]
public UserInfo GetUser() { return new UserInfo(); }
}

When consumed in the client (via visual studio add web reference to build proxies), UserInfo is treated as two different class definitions. How can I "share" the definition.

Thanks in advance, Jeff

hi Chilberto,
What you have to do is make a DLL project that defines the UserInfo class and add reference to both webServicies, that will solve the problem.
Hope that helps.

See if the manufacturer of the device has an SDK (Software development kit) for it. Without an SDK or reference for the device drivers for the device, you're out of luck. There is no such thing as "just accessing USB." Every device is different and requires its own driver. USB is NOT a generic access method for devices attached to it. It's an expansion bus, just like PCI, and just like PCI, each device must have it's own driver in order to communicate with it.

well i have the option to purchase RS232 interface rather than USB, would this be better for me ?
or is it much the same if i have SDK for USB ?

if i can get the driver, is it then a matter of listening to a certain port ?
or is it more low level requiring hardware instructions ?
or is it driver dependant?

sorry alot of question

kind regards

Your still going to need to have the docs on the device so you know what commands the device accepts, how to format them, how to parse any data that comes back, ...

If you don't have the driver, the device won't work!

g00fyman wrote:

It's very hardware dependant. No matter what, you'll need some kind of documentation describing the command interface of the device. Without it, it'll be like your speaking Chinese in Oklahoma, if you even get to Oklahoma.

C# Sql INSERT statment

I am trying to insert data into a Access db. I am able to connect to the db fine. I get an error in the catch telling me I have a problem with my sql statment.

This is my sql statment. (I have checked the spelling of all variables and field, table names etc...)

All information is comming from textboxes

--except newNum -- uses a method to find the next avalible number

(worked like this on a different db)

string sqlString = "INSERT INTO Cafe (CustomerNumber, FirstName, LastName, Address, City, Province, PostalCode, PhoneNumber, UserName, Password, TimePurchased ) VALUES ("
+ newNum.ToString()
+ ",'" + FirstNameTxt.Text
+ "','" + LastNameTxt.Text
+ "','" + AddressTxt.Text
+ "','" + CityTxt.Text
+ "','" + ProvinceTxt.Text
+ "','" + PostalCodeTxt.Text.ToUpper()
+ "','" + PhoneNumTxt.Text
+ "','" + UserNameTxt.Text
+ "','" + PasswordTxt.Text
+ "'," + TimePurchaseTxt.Text.ToString()
+ ")";

the Access db is called Assignment3

the table is called Cafe

CustomerNumber (autoNumber) PK
FirstName (Text)
LastName (Text)
Address (Text)
City (Text)
Province (Text)
PostalCode (Text)
PhoneNumber (Number)
UserName (Text)
Password (Text)
TimePurchased (Number)

I am new to sql and would really like some help

Thanks

Remove the autonumber, and it would be better controlled by Access itself instead of your function.

Include the error message in the email. Also, provide the value of sqlString at runtime which would be easy for us to look into.

The autonumber is controled by Access. each feild does have a value when I debug.

You cannot insert into an AutoNumber column. Either make the column a regular number column, or do not include the column in the INSERT statement (allowing the database to assign it the next available number).

Also, your code is extremely susceptable to a SQL Injection Attack. You should read SQL Injection Attackes and Tips on How To Prevent Them[^]

I still have a problem....this is what I did to remove the CustomerNum

string sqlString = "INSERT INTO Cafe ( FirstName, LastName, Address, City, Province, PostalCode, PhoneNumber, UserName, Password, TimePurchased ) VALUES ("
+ FirstNameTxt.Text
+ ",'" + LastNameTxt.Text
+ "','" + AddressTxt.Text
+ "','" + CityTxt.Text

+ "','" + PostalCodeTxt.Text.ToUpper()
+ "','" + PhoneNumTxt.Text
+ "','" + UserNameTxt.Text
+ "','" + PasswordTxt.Text
+ "'," + TimePurchaseTxt.Text
+ ")";

Error -- Syntax error in INSERT INTO statment

Thanks for your help!!
