Two things. 1) Limit your sample size. Run as little of the app under the profiler as possible or limit what the profiler is sampling, or 2) increase the RAM in the machine. My Dev box at home has 16G in it. My work laptop has 4G. Guess which one I do my profiling on... A guide to posting questions on CodeProject[^] Dave Kreskowiak

formatter.Deserialize(s) assumes that the entire object has been successfully written to the stream? For grins and giggle, try writing the entire stream to memory after 30 rows; I bet a dime to a dollar, all of your strings have not been completely written. At least that is what I would look into, don't know the answer myself as I completely avoid WCF like the plague. Need custom software developed? I do custom programming based primarily on MS tools with an emphasis on C# development and consulting. I also do Android Programming as I find it a refreshing break from the MS.

I don't have any tips or resources for you, but I had to do this same thing about a year ago. It started out as a simple app where the user would select the data tables and columns to see, then the users wanted the ability to write custom filters (custom where clauses for the select statements), and reorder the data, and group the data, and have embedded sub reports, and have static page headers and footers, etc, etc. It turned into a huge project. Good luck! Don't blame me. I voted for Chuck Norris.

Worked perfectly, thanks Mark.

LINQ will ignore nulls by default...you shouldn't have to explicitly check for it. Remove the !fm.IsfkFamilyNull() from your join and see if that works.

Your welcome I've had similar issues when not assigning a value to a NOT NULL DateTime field, and then i get some ambigious error message at ctx.SubmitChanges();... took forever to find it Glad you sorted your problem out Harvey Saayman - South Africa Junior Developer .Net, C#, SQL you.suck = (you.Passion != Programming & you.Occupation == jobTitles.Programmer) 1000100 1101111 1100101 1110011 100000 1110100 1101000 1101001 1110011 100000 1101101 1100101 1100001 1101110 100000 1101001 1101101 100000 1100001 100000 1100111 1100101 1100101 1101011 111111

Thanks Peter, That did the trick. I spaced out on that one.... Ryan

I think that OpenNetCF has a named mutex implementation that can be used across different processes, but I am not sure about it. The most common solution is to check if a Window is already present and not start a new process: [DllImport("coredll.dll", EntryPoint="FindWindow")] private static extern IntPtr FindWindow(string lpClassName,string lpWindowName); [DllImport("coredll.dll")] private static extern int SetForegroundWindow(IntPtr hWnd); [MTAThread] static void Main(string [] args) { string windowName = "MyForm"; IntPtr window = FindWindow(windowName); if (window == IntPtr.Zero) { Application.Run(new MainForm(windowName)); } else { SetForegroundWindow(window); } } This is not a bullet proof solution, but it works.

I'm confused, how does this question rate a 1.2? It is asking about training in a training forum. Is there something I'm missing?:confused: Learn to write self marginalizing code! Call 1-888-BAD-CODE ------------------ Silver member by constant and unflinching longevity.
