As Sandeep correctly mentioned, you're looking for the wrong directory.
You need to wrap "Drive" in a call to Server.MapPath() as well when calling System.IO.Directory.Exists(), otherwise you're actually searching for a Direcory named "Drive" instead of the mapped one.

Hi,
I am a writing a program in which a user can open a file in some application by creating a new instance of that application. But what I want to do is see if that application is already open (the user opened it not through my program, but by double clicking the application icon) in which case use the already open application to display the file instead of creating a new instance.
How can I do it.
Thanks

One way to do this
if ( System.Diagnostics.Process.GetProcessesByName("processname").Length == 0 )
MessageBox.Show("Process not running");
else
MessageBox.Show("Process is running");

Mr. Sandeep,
I guess you got the question wrong. Once I find that a application is already open, Is there a way that i can open a file in that, instead of creating a new instance of the application and then opening a file.
Thanks

There is, and a simple search for single instance application[^] would return several results, including Single Instance Application in VB.NET[^], which should be easy enough to translate (it's mostly calls to the BCL).
You can also communicate with the first instance through .NET Remoting - the preferred method - or native RPC, named pipes, DDE, or many other ways (but those are all native, which requires extra code in order to call necessary APIs).

Have you tried using acimp utility in the frameworks BIN folder on the activeX component, it should produce .net assemblies for you to use with your app.
|
|
|
|
|
There's samples on this website. I'm pretty sure. Do a search.

If you've dragged the control from your toolbox (after customizing and adding it to your toolbox) to the form, or if you've used aximp.exe (not acimp.exe like the other poster said), then you reference both the AxInterop.*.dll and Interop.*.dll (or whatever you called them if you used aximp.exe and specified the /out switch). These are the ActiveX control (derived from System.Windows.Forms.AxHost) and the RCW (Runtime Callable Wrapper, a wrapper around the COM server generated from the typelib) respectively.
After you've done that, read the documentation for the ActiveX control on Macromedia's web site (or just take a stab and guess). The classes, interfaces, enumerations, methods, properties, etc. are all the same as they would be from a COM client like Visual Basic or some scripting language, because the RCW is marshaling calls to the COM (automation) objects themselves that scripting clients use.
There have also been articles on this site written about similar topics (perhaps even embeddeding the Flash player). I suggest using the search bar underneath the CodeProject logo at the top of the page to search for existing articles.

Get IsoBuster: www.isobuster.com[^] (go to site and click on download on left.) The free (non-Pro) version does everything I've needed.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

I need your help on following code segment.
DataSet ds=new DataSet();
da.Fill (ds, "Price");
DataTable newdt=new DataTable();
for (int i= 0; i<=ds.Tables["Price"].Rows.Count-1; i++)
newdt.Columns.Add(i.ToString());
for (int i=0; i<=ds.Tables["Price"].Columns.Count-1; i++)
for (int y = 0; y<=ds.Tables["Price"].Rows.Count-1; y++)
dr[i]=ds.Tables["Price"].Rows[y].ItemArray[i].ToString();
newdt.Rows.Add(dr[i]);
What I am trying to accomplish is to loop through one data set and do a flip-flop of data on the fly, ie. rows on the first dataset table become columns of the finished one's. Then bind the result to UI control.
The data in the table looks like this:
DisctType/QtyBreak/UnitPrice
A........./0 to 100/$10.00
A........./101 to 300/$9.00
B........./5000 & up/$2.25
The UI has to make data look as follow:
DisctType/A........./A.........../B
QtyBreak/0 to 100/101 to 300/5000 & up
UnitPrice/$10.00../$9.00....../$2.25
I think I am down to last two lines but just could not pull it off.

I created a windows service in c# and then installed it using both the InstallUtil and Setup project options in VS.NET but the service is NOT available from the Services Management Console.
I even went ahead and created a bare-bones windows service, installers included, compiled it and installed it but it is a NO SHOW as well.
I am in the administrators group of the machine I am using to develop.
Does anybody has an idea what else do I have to do to get to the Services Console?

What Installer classes are you using, specifically? You must use both ServiceInstaller and ServiceProcessInstaller, and both instances must be added to your Installer derivative's Installers collection property. Additionally, your Installer derivative must be attributed with the RunInstallerAttribute.
When running InstallUtil.exe, display verbose output with the /v command-line switch and make sure your type (your Installer derivative class) is found.
If you right-click in the Windows Service designer, you can click "Add Installer" or something like that. Examine the code there to make sure you're coding your installer correctly.

All that is in place.
The /v option doesn't give me any hint of error anywhere, everything is found, compiled and committed.
By the way this is a Windows 2000 (v5.) machine.

You might consider posting your Installer derivative source. There's most likely something wrong with the source code.

InstallUtil does complain about missing public installers but this is automatically generated code!
InstallUtil log file
"No public installers with the RunInstallerAttribute.Yes attribute could be found in the c:\...\visual studio projects\windowsservice1 \bin\debug\windowsservice1.exe assembly.
Remove InstallState file because there are no installers."
But...
The code generated by C# automatically puts [RunInstaller(true)] not [RunInstallerAttribute], is this a bug? I am using .Net 2003.
This is the code generated by C#
[RunInstaller(true)]
public class ProjectInstaller : System.Configuration.Install.Installer
{
public System.ServiceProcess.ServiceProcessInstaller serviceProcessInstaller1;
public System.ServiceProcess.ServiceInstaller serviceInstaller1;
private System.ComponentModel.Container components = null;
public ProjectInstaller()
{
// This call is required by the Designer.
InitializeComponent();
}
...
private InitializeComponent()
{
// serviceProcessInstaller1
//
this.serviceProcessInstaller1.Account =
System.ServiceProcess.ServiceAccount.LocalSystem;
this.serviceProcessInstaller1.Password = null;
this.serviceProcessInstaller1.Username = null;
//
// serviceInstaller1
//
this.serviceInstaller1.DisplayName = "A Windows Service";
this.serviceInstaller1.ServiceName = "Service1";
//
// ProjectInstaller
//
this.Installers.AddRange(new System.Configuration.Install.Installer[]
{ this.serviceProcessInstaller1, this.serviceInstaller1
}
);

In C#, "Attribute" is not required for classes that end in "Attribute" and that derive form Attribute. This is documented.
I do see a problem even with the auto-generated code - namely the properties that you filled-in, or rather didn't fill in. If you read the documentation for the ServiceInstaller.ServiceName property, it is crucial that your ServiceBase.ServiceName (ServiceBase is what you extended, of course) and your ServiceInstaller.ServiceName match exactly. I'm hoping you didn't call your Windows Server "Service1" (the name that you pass to net start or net stop). You need to disambiguate and give it something meaningful (like w3svc for the HTTP service in Windows NT, or iisadmin for the IIS Administration Service).
