Re: SelectedPath() not working in FolderBrowserDialog Robert Rohde12-Jun-05 4:19 Robert Rohde 12-Jun-05 4:19  I think the FolderBrowserDialog class has a bug with paths with more than 256 chars.

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.

What you want to do is not an easy operation because it's tightly tied into the lower-level hardware of the NIC.

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.

Michael CP Blog [^] Development Blog [^] Web Service shared class definition chilberto9-Jun-05 0:53 chilberto 9-Jun-05 0:53  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 Re: Web Service shared class definition NassosReyzidis14-Jun-05 1:27 NassosReyzidis 14-Jun-05 1:27  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. GanDad accessing HID + c# g00fyman8-Jun-05 23:54 g00fyman 8-Jun-05 23:54  hello to everyone, i need some idea of how to access a USB HID magnetic card reader in C#. i have googled quickly and search these articles but have not found anything revealing. does anyone know if any quick tutorials to acheive this ? kind regards, g00fy Re: accessing HID + c# Dave Kreskowiak9-Jun-05 6:45 Dave Kreskowiak 9-Jun-05 6:45  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.

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, ... g00fyman wrote: if i can get the driver, is it then a matter of listening to a certain port ? If you don't have the driver, the device won't work! g00fyman wrote: is it more low level requiring hardware instructions ? or is it driver dependant? 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.

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 Re: C# Sql INSERT statment codeprojectin8-Jun-05 23:47 codeprojectin 8-Jun-05 23:47  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. Re: C# Sql INSERT statment Rinventive9-Jun-05 0:25 Rinventive 9-Jun-05 0:25  The autonumber is controled by Access. each feild does have a value when I debug. Re: C# Sql INSERT statment Colin Angus Mackay8-Jun-05 23:56 Colin Angus Mackay 8-Jun-05 23:56  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.

Re: C# Sql INSERT statment Carsten Zeumer9-Jun-05 0:54 Carsten Zeumer 9-Jun-05 0:54  what does the sqlString look like if you dump it to the console? Since you do not quote you parameters it is possible that they contain quotes or commas... /cadi 24 hours is not enough Re: C# Sql INSERT statment Rinventive9-Jun-05 0:57 Rinventive 9-Jun-05 0:57  I'm not sure what you mean "dump it to the console" and none of the text input has anything other then letters and numbers. I'm new to this...Thanks
