Ok I have got my page to display the data I need using a store procedure etc. What I need to know is, how do I create an input text form box (IE: Enter ID here Smile | :)

with a submit button and pass that variable to the (ident = 1) below to make it (ident = textboxvariable). Any help would be appreciated thanks! =)

<%Dim ident

'select your product_id
ident = 1
Dim connection
Dim rs

'create the connection
connection = Server.CreateObject("adodb.connection")
'create the connection (here we used a DSN - use any standard connection
connection.open("Driver={SQL Server};Server=X;Database=trd;Uid=X;Pwd=X;")

'create the recordset
rs = Server.CreateObject("adodb.recordset")

'open the recordset, passing in the variable
'note that the variable product_id does not have to be name the same as in the stored procedure, it just needs to be the same data type.

rs.Open("Exec GETID " & ident, connection)

'display the recordset
Do Until rs.EOF
For Each ident In rs.Fields
Response.Write(ident.value & "<br />")
Next
Response.Write("<br />")
rs.MoveNext()
Loop
rs.close()
connection.close()%>

Objects, Databases and best practice

Hi All,

I have a business object, an "Asset", which takes it's data from a database table. Now, the "Asset" has a field called CompanyID, which is an int. This is great for the database, program and developer(me), but users might baulk at having to refer to numbers. Naturally, CompanyID is a relation to another table in the database.

So my question is: what's the best way of including a human friendly CompanyName in the Asset object? I could create a property which is filled in when the object is created from the db data, or I could have the object look up it's CompanyName whenever required or... What's the best thing to do?

Thanks,

Martin.

I'd expect the class to have a private ID and a public string for the name. Any object once read is disconnected from the database unless you re-read it, generally I think it's accepted that what you're looking at is the object at the moment you first requested it.

What I usually do is to join in the company table, so that I can fetch the company id and the company name in the query. Then I create a Company object from those, and store that object in the asset object.

To access the name of the company, I use: theAsset.Company.Name

You now have two choices lazy or earlier instantiation

Early:

public class Asset{
    private Company company = null;
}//end Asset

Have the DAL immediately load company

or lazy:

public class Asset{
    private Int32? companyID = null;
    private Company company = null;

    public Company Company{
        get{
            if(this.company == null && this.companyID != null){
                ... Get it
            }
            return this.company;
        }
    }

}

in early your DAL will just fill the company

Hi there:
As you know we can compile a C Sharp program at DOS prompt like

csc MyProgram.cs

Where MyProgram.cs is the source code file.

Now i want to perform the same compilation through another C Sharp Program. Like i made a program named ShellExecution, which tries to compile another C Sharp Source Code File called "First.cs" lying in my c directory. The program runs fine without any exceptions; it opens the dos window and runs csc, but nothing happens and seems like the file name "First.cs" is not being passed to the csc.exe as a parameter. I have used the following code for executing the compilation process:

System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = "C:\\WINDOWS\\Microsoft.NET\\Framework\\v2.0.50727\\CSC.exe";
process.StartInfo.Arguments = "C:\\First.cs";
process.StartInfo.UseShellExecute = true;
process.StartInfo.RedirectStandardOutput = false;
process.StartInfo.CreateNoWindow = false;
process.Start();
process.WaitForExit();

Please help me out!!!!

Why don't you take a look at the Microsoft.CSharp namespace? That's got some wrappers around the compiler.

As of how to accomplish this I wouldn't have a clue at the moment and I'm too lazy to google it

No, i dont have to use Microsoft.CSharp.
Its a requirement to use shell execution either through ShellExecute API or through the System.Diagnostics.Process namespace(as i have done in my code). Please anyone help me. I'm stuck.

Get Running Processes Using A Library [modified]

I was wondering if there was a way to determine application dependencies at runtime..

I have several applications sharing a managed library registered in the GAC. When I need to update that library (not changing its version info, so that I dont have to recompile the programs to use the updated library), I need a way to see what open processes are using that library so I can kill them before the update.

If anyone has any suggestions, please let me know.

Thanks is advance,
Aaron

Hello

If you already know all the applications that could possibly be using that library, you could look the up using Process.GetProcesses Method. Otherwise reboot in safe mood, then replace it.

Within your window form, or to a web browser?

If you want to open it to a web browser, you choose among Process.Start(), ShellExec(), or ShellFileOperation().

If you want to open it on your window form, add a web browser control to the form and call its Navigate().

ProcessStartInfo supports limited options on the opened window: hiden, minimized, maximized, normal. Other window styles have to go through the client program, "iexplore", for example.

Hi,

Im trying to make a program to communicate with something that is connected with the serial port.

The device i wanna connect to the serial port knows several commands.

So basically there needs to be a simple connection with the port so that i can put commands in the console and the device reply's me and sets its output on the console.

So far i got this:

static SerialPort serialPort;

public static void Main()
{
serialPort = new SerialPort("COM1", 19200, Parity.None, 8, StopBits.One);
}

I hope someone could help me a bit.

Thanks in advance!

Hello Devs,
I'm new to Compact Framework Programming. I'm porting a Chat application to Window Mobile. I noticed that whenever I create and oshow a new instance f Form, its shown as a seperate procees in Running Prgrams. 10 forms means 10 Processes in Running Programs WTF | :WTF:

.
To avoid this to happen, I thought to work with tab controls and adding a tab page to the tab control when a user initiates chat with a new person.
What I want is that I want to add and remove pages dynamically. For this when I tap and hold on the node of the tab page (equal to Right Click) a context menu should open "Close Tab" and Taping this menu item that specific Tabpage should be closed. I have tried to do it with Context Menu but It does appear when you tap and hold on the tab page, not its node Cry | :((

I have tried to be clear in telling my problem but even if you need some more clarity and info please ask me.

I really want to get a solution (Its so urgent)
I hope to get a positive response from you people.

Best Regards,
Rizwan

It depends on which event you handled. Either TabControl.MouseDown, or TabPage.MouseDown. In your case you probably consumed TabPage's not the TabControl's event.

Handle TabControl.MouseDown event and check TabControl.SelectedIndex
