My point exactly.
I'd also refer to Edison and his 10000 ways that don't work.

I created a C# Windows Service to clean up files on some equipment PCs. Along with the service I created a configuration Windows App. that allows me to install, start, stop, uninstall the service and create an configuration XML file to change folder locations and such.
Purpose:
The service uses an OnTimer event to periodically check a folder for files. It then creates a backup copy on a network drive and deletes the local file.
Problem:
The following code does not work in the service but will work if performed from a button in the configuration app. The AddToFile function is working in the service as it just writes the string to a text file.
The Service is configured to log on as a local system.
Question: Why does this not work from within the service?
//Code Section
AddToFile(DateTime.Now.ToShortDateString() + " " + DateTime.Now.ToLongTimeString() + " Copying Reports to Network");
foreach (string sfi in Directory.GetFiles(SC.LocalReportFolder))
{
FileInfo fi = new FileInfo(sfi);
FileInfo fn;
if (SC.CU.AppendMachineName) //Configuration file variable
{
//Adds the machine name to the report
string nwname = fi.Name.Replace(fi.Extension, "_" + SC.MachineName + ".txt");
fn = fi.CopyTo(SC.CU.NetworkReportFolder + "\\" + nwname, true);
}
else
{
fn = fi.CopyTo(SC.CU.NetworkReportFolder + "\\" + SC.MachineName + "\\" + fi.Name, true);
}
fn.Refresh();
//If the copy was successful then delete the local file.
if ((fn.Exists)&&(SC.CU.DeleteLocalReport))
{
fi.Delete();
}
}
//End of Code

Hi,
my first hint would be that the local system account doesn't have the appropriate rights to access the network folder.

After some further searching I found that a service cannot use an existing mapped drive. It must create the map itself to work. This also has problems as a service may start prior log on an thus the network is not available.
Looks like I may have to use my Windows App in the startup folder with a timer or filewatcher event.

Or periodically check for the existance of the drive.
P.S. I don't use mapped drives. (They're so '80s!)

If you're going to access a file system on another computer, your service has to be installed with a user account that exists on the remote system. The default user for a service is "Local System" or something like that. So, you need to have (or create a new) user account with appropriate permissions on the remote system, and then install your service with those account credentials on your local box.
Put a try/catch block around your System.IO calls, and you'll see exactly why they're failing.

I'm writing a soap client that interacts with a web service. I let Visual Studio create the proxy classes from the WSDL file.
During the first soap request, the proxy class's InvokeAsync methods takes about 20-30 to return. I doesn't matter which
soap request I make, the delay is always there the first time. All subsequent soap request return immediately from InvokeAsync.
I subclassed SoapExtension, and set a breakpoint in ProcessMessage. The delay occurs after BeforeSerialize and before AfterSerialize.
Any idea of what is going on, or how to further debug this? Thanks.

don't know. the delay, as far as i can tell, seems to be during the serialization process, and before the request get sent. i dump the request and response xml to a file, and they're less than a second apart.

What is your question? Do you want someone to tell you how to build the entire system? That's not going to happen. The purpose of this forum is to provide solutions to specific programming questions, not to do someone's work for them. I suggest you purchase a beginner's ASP.NET book and work your way through it.

Thats a great idea. You're a funny guy Paul.
However, I am not looking for someone to build the whole system... I'm looking for some advice re: good articles to reference etc and starting points...

Not really. All I did was to point out that your question was of too general a nature to be answered in this forum.
Read the forum rules, paying specific attention to no.2.
I suggest you post again if you have more specific questions relating to the implementation of your project.

I need to be able to parse the following line, I am not even sure regualar expression are
the best option.
LIC#:ABC123 YRMD:03 MAKE:CHEV BTM :CP VIN :1G1JC12F137230800
into
LIC#:ABC123
YRMD:03
MAKE:CHEV
BTM :CP
VIN :1F1JD12F137230735
And then capture the data after the semicolon.
All can be variable length and there isn't a delimiter
Unfortunately, you also can't depend on the tags having no spaces with the colons (i.e. VIN :, vs YRMD:.
I have been trying to use Grouping to parse this.
I am newish to regular expression and thought maybe I should use them to solve this problem.
Are regular expression even a good fit for this problem?
Any suggestions appreciated.

You don't parse with regular expressions.
Try something like this:
private string SplitValue(string str, char delim)
{
string[] parts = str.Split(delim);
return parts[1];
}
private bool Test7()
{
bool result = false;
string original = "LIC#:ABC123 YRMD:03 MAKE:CHEV BTM :CP VIN :1G1JC12F137230800";
string[] parts = original.Split(' ');
if (parts.Length != 7)
{
return result;
}
string license = SplitValue(parts[0], ':');
string yrmd = SplitValue(parts[1], ':');
string make = SplitValue(parts[2], ':'); ;
string btm = parts[4].Replace(":", "");
string vin = parts[6].Replace(":", "");
return true;
}
The code above is based on the string you provided. Since there appear to be spaces in places where there really should be none, you can't really get away with a single split command, so you have to improvise. Yeah, I could have used substring instead of writing another function to split the first three parts, but what the hell, I had time...

Thanks, I would taken a much more difficult approach.
That is embarrassingly simple.

Perhaps you could replace " :" with ":" to fix that and make processing easier.
After that, if values don't contain SPACEs then you can split on SPACE and then on colon as mentioned.
Certainly a Regular Expression could be used if the data is regular enough, but why not perform both tasks at once?

Yes, I had just tried that myself.
That one was looking me right in the face.
