Windown service not starting
hi all,
i have written a small service.now when i install the service, the service gets installed what i feel but is not able to start. using an installer i am installing the service application in windows vista.
it gives out an error during installation, when the service is getting started.
it throws an error as follows:
Create process failed: error code 14001. the application has failed to start because the application configuration is incorrect. reinstalling the application may fix the problem.
i tried reinstalling, however the same problem persists...
i am pasting the code below,, for initial main, service installation and service start functions..please can i get some help on fixing the error....

all the variables used have been declared and there are no compilation error...
using visual studio 2008 for service application development for windows vista...
Thankuou...
Re: Windown service not starting
First of all debugging the services is really hard work.
Second: use code outlining it will be much more readable for us mortals.
Third: Install on Vista Visual Studio 2008 redistributable, to get the appropriate dll-s
Forth: don't use MessageBox or any GUI unless "Allow service to interact with desktop" is checked.
And last if you want to make your life easier with the services check this service template:

Re: Windown service not starting
Making your post readable using these and removing all those empty lines helps ALOT.
Re: Windown service not starting
Is your goal to learn how to hand write a service or is the goal to get the service code running quickly so you can get on to coding the rest of the functionality?
If the latter, then I suggest you start creating the service by using the ATL Service template. Using the ATL service template, you can get a service created, and registered in about 5 minutes.
