Executing an exe file from a Windows Service

27-May-07 4:54

You must have AxWMPLib in your reference of your C#-project.

Then you have to add the Mediaplayer as a control to your form.
For instance, name the control to "WMP".

After that you can do.

WMP.URL = "the musicfile full path";
string cName = WMP.currentMedia.name;

I triedto execute a notepad application in windows services using
1. System.Diagnostics.Process.start("notepad.exe")

2. System.Diagnostics.Process process1 =new System.Diagnostics.Process();
process1.StartInfo = new ProcessStartInfo("NOTEPAD.EXE");
process1.Start();

and by giving full path also i.e "c:\windows\notepad.exe"

But the application is not started and it is not showing error also.
Could you please give a suggestion.

Please it is very urgent.
And I want to know how to get the acknowledgment from the process that i has been executed successfully.

I have a question. Why would you want to do this? The purpose of a windows service is that it is running as a set user that you define in the login tab. This allows the windows service to run all the time not just when someone is logged into the computer. Ok that being said.

I would guess that you are running your windows service with a login that doesn't have rights to open notepad, or that the window service perhaps is not running. The way you are going about trying to open note pad should work fine. Perhaps you should check the event log to see if any errors are getting logged. You could also do some event logging in your windows service. You also might want to put a try catch around the call to your process to open notepad, you might be getting an exception.

Hope that helps.

By chance I've come across this problem some time ago, too.
I wanted to create a service that's listening for PowerEvent and SessionChange events (suspend/resume windows) and executes applications in a given directory (similar to Autostart, but being executed even when the computer is restarted from suspend mode.

Unfortunately, I couldn't get it to work, no matter what I tried.
I could get the service to start the applications, but the application windows didn't show. Neither UseShellExecute=true nor UseShellExecute=false made any difference.
I couldn't find out why and the project was forgotten after a while...

So if anyone can help I'd be interested as well.

Regards,
mav

This is what M. J. Jaya Chitra found:

Thanks for your reply.
I am having sufficient privileges.
Now I got the answer, I have checked the option 'interact with desktop' in the 'Log on' tab in the service properties window.

But this leads to another question, this is done manually is there any provision to change this property while designing the service itself

weird problem with ComboBox - DataSource contains data, but the Items collection stays empty

I don't know any way of doing it, but that doesn't mean it can't be done. If you search through the ProcessInstaller you may find a property that would install the service as checked.

I created a custom control which simply is a data-bound ComboBox. It has a custom property that causes an ArrayList of KeyValuePair elements to be passed to the DataSource property. It also sets the DisplayMember and ValueMember properties.

What's weird, is the fact that my control sometimes works fine and sometimes it doesn't. I have no idea why, but when I put on Form1 everything is fine, while on Form2 the Items collection stays empty, although the DataSource property contains data and it is exactly the same data (pulled from the database in the same way) that I use in case of Form1.

I tried to use a DataTable instead of an ArrayList, but it changed nothing.

Does anybody have any suggestions?

I found a solution.

It seems that the problem was caused by the fact that in one the windows (Form2) I was trying to access the Items collection in the window's constructor. Even though I put my code after the InitializeComponent method, the combo box must've been still not fully initialized. I moved the code to Form.Load event and everything works fine.

C# Control for volume

Hi
Does anyone have a tip about a nice C#-control for volumesettings ?

The common trackbar will do, but i need one where i can set Backcolor to Transparent, and the standard trackbar does not accept that.

Any tips ?

With Kind Regards

Either you search for custom control or you write your own Smile | :)

Could you create a user control that inherits the trackbar and use SetStyle to allow a transparent backdrop?

Ok , that could be an idea.

I do not know how to use the SetStyle, but i will check that out.

Thanks.

SetStyles(System.Windows.Forms.ControlStyles cs, boolean b)

To try to have a transparent backcolor, you would use setstyle in the initialization of the control.

SetStyle(ControlStyles.SupportsTransparentBackColor,true);

Their are also a few other painting routine properties that you can set to true, the properties assist in reducing flickering from custom paint routines.

Ok..now i have tried , but....

As i can see....i can set my usercontrol to transparancy but i am not allowed to set the Trackbar-control backcolor to Color.Transparent anyway.

Are you using .NET 1.1 or .NET 2.0?

How put the PNG-Pictrue into the pictureBox?

28-May-07 9:50

I using NET 2.o and VS2005.

Maybe it's lack of competence from my side, but i cannot figure out how to set the background to transparent of the Trackbar.

The only way i see is to redraw my own style trackbar.
