Windows Service and Process Class [modified] - C# Discussion Boards

I got anxious and continued to do research while I waited for an answer. The only one I kept seeing over and over was VisualSVN, so I setup the server, installed the client, and it made me download TortoiseSVN. I don't need the 3rd one.

I have been playing around with it using my desktop, and laptop, and so far, I am loving it.

I'm using this and it works very well. Looks & feels like VSS 6.
It's free for single user.

Everything makes sense in someone's mind

Why do you have to use LINQ ?

hi,

There is a LINQ forum

only two letters away from being an asset

Hello everybody,
I have a problem to which I haven't been able to find an answer through Google. I am making a windows service that reads image files in an input folder and then profiles the document in a document management system. The program can't manipulate images itself so it's OCR and Barcode reading, and image splitting, converting and combining functions are performed in separate applications using the System.Diagnostics.Process class.

The problem I am running into is that when I call my TiffSplitter app I get a System.OutOfMemoryException when I the image is first loaded into the program. In initial testing I found that I could set the "Allow service to interact with desktop" property of the service and it would run on my development PC but this quick fix didn't solve the problem on a client site.

I know that setting that property isn't a proper solution either so I'm open to ideas as to how to properly fix this. The reason this program is a service is so that it will auto start on system startup and doesn't require a windows user to log on to windows to start working. Is there any way of increasing the amount of memory that a process can use? Or is there some other solution that I'm missing?

Here some info about The PC's and the Program:
Development PC-
OS: WIN XP with SP2
Pentium 4 2.80GHz
2GB Ram

Client Server-
OS: WIN Server 2003
Runs on a virtual machine

TiffSplitter app-
vb6 app
Uses Imaging Pro to split and OCR Tiffs
Program loads fine but errors out on the image loading functions

Service app-
C# 2.0 app
Uses following code [Paraphrased] to open TiffSpliter:

using (Process p = new Process())
{
    p.StartInfo.CreateNoWindow = true;
    p.StartInfo.UseShellExecute = false;
    p.StartInfo.Arguments = [args];
    p.StartInfo.FileName = [exe];
    p.Start();					
    p.WaitForExit();
    p.Close();
}

Hi,

When we loop through some thing with out an End, we usually get this error.

So please check all your methods, or just create a log files for each method,

and identify is there any loop goes on.

Because your tiny program will have the sufficient memory untill some thing goes wrong.

(i have not given the solution, just its my observation on your post)

Thank you for your reply.
There is no infinite loop as your proposing. I know this because the exact same code will run on in a console app on the desktop with the same input. Also the line of code that throws the error is not in a loop.

If you're processing TIFF files, make sure your VB6 app isn't trying to display the image. GDI and GDI+ do not support JPEG compressed TIFF images, so this could be the cause of your problem. I'm not familiar with the library you're using so I cannot comment on the reliability of it.
