i want to get some projects created in c# please tell me how can i take them like
school management system
hospital management system
inventory management system

Yeah, ..... right.
You want someone to completely describe how to design and build these systems .... from the ground up .... in a couple of forum posts .... ?
This is something that would take entire books to describe. If you can't start with gathering a GOOD set of requirements, you're going to fail ... miserably.

I don't think he wants an explanation, just something he can scrawl his own name on (in crayon, I suspect) and hand in as his assignment...

Yeah, I know.
Just ignoring the question will only make him repost it again and again until he either has nothing to turn in or just gives up and drops the class.

Yep! Pretty much why I'm not as involved as I used to be.
Well, that and the pile of frickin' work I've been under for the last couple of years.

Aight; first, don't repost and bump your question.
Second, this is a description (as Dave already said) of work to be done - there is no specific problem. What do you want help with? Did you look at the keydown-handlers? What code have you tried?

Just repeating the same thing without answering our questions isn't going to get you any useful answers. You STILL haven't provided enough detail to answer your question.

try key down event of your grid. and if this not working, then show your code and r&d

hi everyone I'm not in this c# language so I need to ask this from you guys.  we have this project computerized system of checking a multiple choice question exam using c# visual studio 2012.How can we compare the answer sheet with the masker key so that we can get a score? We cannot proceed to the next step because we are stuck in this step . Hope to answer from someone who is good in c#. Thank you so much

You haven't given enough information for anyone to help you.
On what technical point are you stuck?
The difficult we do right away...
...the impossible takes slightly longer.

in comparing the master key to the student's answer sheet. do you have any idea what part of image processing can we apply?
|
|
|
|
|
STILL not enough information. What format is this master sheet in and what format is the student answer sheet in? Are we talking about those little dots you fill in all over a sheet of paper or are we talking about something handwritten?
|
|
|
|
|
Im sorry for not stating clearly.
Are you familiar with the OMR sheets? Our format is similar with that but instead of bubbles its just square. And for the master key, we made gui for it and inside the gui are the 100 items with 5 choices from A-E. We can edit the master key everytime we check an exam. So the problem is we still don't know how can we compare the scanned answer sheet of the students and our master key so that we can get the correct answer.
I hope this will do.

It's going to take some image processing to "find" the possible answers on the sheet and identify which answer was selected for a question.
To this end, you'll also have to come up with some kind of way to denote which question answers appear where on the page and also which answer would be the correct one, for every question on the page. You'll have to build a map of this data.
BTW: This will be time consuming for the person using the system.
Google for "machine vision" and start reading. You're going to have to do a bunch of research on this one.

I used the following code for multi-threading, The code works fine but much slower if I add the tasks[nData].wait() command see below "*****" but if I remove the tasks[nData].wait() command then the code generates all the task but only gathers information for approximately 150 task then stops. Can anyone tell me why this is happening and what I can do to correct this problem.
Any help will be greatly appreciated.
Michael
public Boolean LoadData()
{
Boolean bComplete = false;
Int32 nTotalData = 10000;
this.tasks = new Task[nTotalData];
DateTime dtStartTime = DateTime.Now;
ProcessingBarsCS.StartTime();
var parent = Task.Factory.StartNew(() =>
{
dtStartTime = DateTime.Now;
for (Int32 nData = 0; nData < nTotalSymbols; nData++)
{
bComplete = GetData_Task(nData, dtStartTime, nTotalData);
}
});
parent.Wait();
ProcessingBarsCS.StopTime();
return bComplete;

My guess is that you had a SystemOutOfMemoryException. Try to check the Event Viewer for possible error messages that the application has thrown. Also it would be wise to set a limit for the number of tasks that will be created so as not to overload your machine.
Signature construction in progress. Sorry for the inconvenience.

Walking this code through:
- You start a new
Task; - You call
GetData_Task 10000 times in a loop; GetData_Task creates a new Task and immediately waits for it to complete;GetData_Task then waits for all 10000 tasks - most of which haven't been created yet - to complete, catching and ignoring the ArgumentException thrown when the WaitAll method encounters the first null element in the array;- The
LoadData method then waits for the parent Task to complete;
No wonder your code is slow!
This code looks like a suitable candidate for the Parallel class[^]:
public bool LoadData()
{
const int nTotalData = 10000;
DateTime dtStartTime = DateTime.Now;
ProcessingBarsCS.StartTime();
Parallel.For(0, nTotalData, nData =>
{
var dataCS = new DataCS();
var result = dataCS.Data();
ProcessingData(result);
});
SetData_ElapsedTime(dtStartTime, nTotalData);
ProcessingBarsCS.StopTime();
return true;
}

Hello,
in my program i have an exception, because i want to synchronize a local directory with a networkDirectory (write Protected).
Message:
Microsoft.Synchronization.MetadataStorage.MetadataStorageEngineException: Fehler bei einem Speichermodulvorgang. Fehlercode: 25039 (HRESULT = 0x80004005, Quellen-IID = {0C733A7A-2A1C-11CE-ADE5-00AA0044773D}, Parameter=(0, 0, 0, H:\filesync.metadata, , , )).
---> System.Runtime.InteropServices.COMException: Fehler bei einem Speichermodulvorgang. Fehlercode: 25039 (HRESULT = 0x80004005, Quellen-IID = {0C733A7A-2A1C-11CE-ADE5-00AA0044773D}, Parameter=(0, 0, 0, (sourceNetworkDirectory)\filesync.metadata, , , )).
I would like to avoid writing the 'filesync.metadata' to the sourceDirectory, or maybe change the path for writing the metaFile
Can someone help me?
Greetings

Hi,
i would like to know best way to develop an application which runs locally. Here is my requirement and how i used to do all these days
Requirement:
1. Develop a application which runs on a frequent interval(may be 1 minute once) in a windows server class os
2. Do something locally and pass the information to remote server by calling a WCF service
Below is the method i used for the above requirement.
1. Develop a windows service application using (VS 2010 ->New project->C#->Windows->Windows Service)
2. Add a Timer and specify Timer.Interval is 1 minute
3. Write a function to do something
4. Call the function in Timer_Elapsed
5. Add installer (ServiceInstaller and ServiceProcessInstallar)
6. Build the applcation
7. Install this app as windows service and start it. (Can be viewed in services.msc)
Kindly let me know is there any better way to do the above.
Thanks in advance
Regards,
Murugesan

Write a normal app, execute it every minute using the Task Schedular[^].
Having your own timer-service would be more resource-intensive, and Windows-services are harder to debug than normal windows apps.

One reason I might use a Service versus the suggested alternative in the other post (scheduler) would be if I want to insure that the task doesn't run too often or too seldom. The scheduler allows it to be changed, turned off.
However insure that a windows service correctly shuts down if the task is still running when a user attempts to shut down the service or on a reboot.
