That's only one of the config files. It's like a blueprint holding the values you enter in Visual Studio at coding time.
What your application saves at runtime is stored in a user-dependent copy of that file somewhere in the region of "Documents and Settings/$YourUserName$/Application Data/$Company$/$ApplicationNameWithSomeAlphaNumericFuzz$/$ProductVersion$/user.config"
The exact location may depend on your OS version.

I found this but nothing inside.
"C:\Documents and Settings\Administrator\Application Data\Microsoft Corporation\Microsoft (R) Visual Studio (R) 2010\1.0.30319.1"
There are no strange company name in Application Data.
Btw thank you for answering.
Edit :
I found it here[^]
It's just like what you answered, I missed Local Settings before Application Data.
Thank you very much.

I have the following Setup:
1) The WPF Thread itself (the MainWindow), which stores the Controls to Display my Content, and the Thread Safe Properties with the content to display.
2) The Update Thread (System.Threading.Thread, not BackgreoundWorker). This Thread updates the Properties of the WPF Thread.
3) The Draw Thread (System.Threading.Thread, not BackgreoundWorker), which actually manipulates the Controls of the WPF Thread (Adding Canvas, Removing Canvas, Setting Text, ...)
My Main problem is the thing, that the WPF Thread is storing the Thread Safe Properties. My Update Routine and Draw Routine are both called very very often (1000 Times a secound).
And thats exactly the problem. The WPF Thread is totally blocked due to the many Get, Set Operations of the other both Threads.
So my first Question is, does someone has an Idea where to store these Properties so the main WPF Thread isn't blocked?
My Secound Problem is the following:
The Update and Draw Thread are both working with the Dispatcher of the WPF thread. If they execute 1000 Times a secound the Dispatcher just runs out of mem (because of too many actions in queue). Is there a way to measure how many actions are in queue and to know if to store another or not. And Secound is there a way to say "Now execute the queue".
I know i can get the state of each dispatcher Object i add. But i don't want to wait till each action is e executed. I want to add as much as possible, so the Update and Draw Thread can run as fast as possible.
My Third side Question is, is my Concept to use WPF for this stupid, or not well planned? Shouldn't i use WPF for this, is there another way to achive my Goal?
My Goal explained:
via Update i have to draw content, very often to be exact, without getting the Part to display the content laggie aka responsive UI.
Please help me with any suggestions or sth else.
As a side Idea i have thought of taking the Thread safe properties into a third thread aka DataThread to store and change, but how can u store Properties into a thread? what is a good way to achive this?
thx in advance
sincerly Synergi
EDIT
Here is an example of one of my Thread Safe Properties. Maybe im loosing much time here. May there is a better Solution for this.
private Nullable<Point> Offset
{
get
{
Nullable<Point> returnValue = null;
object lockObject = objectPool.Aquire();
lockObject = this.offset;
bool locked = false;
bool aquired = false;
System.Threading.Monitor.TryEnter(lockObject, ref locked);
try
{
if (locked)
{
returnValue = this.offset;
aquired = true;
}
}
finally
{
if (locked && aquired)
{
System.Threading.Monitor.Exit(lockObject);
}
}
objectPool.Release(lockObject);
return returnValue;
}
set
{
object lockObject = objectPool.Aquire();
lockObject = this.offset;
bool locked = false;
bool aquired = false;
System.Threading.Monitor.TryEnter(lockObject, ref locked);
try
{
if (locked)
{
if (value.HasValue)
{
this.offset = value.Value;
aquired = true;
}
}
}
finally
{
if (locked && aquired)
{
System.Threading.Monitor.Exit(lockObject);
}
}
objectPool.Release(lockObject);
}
}

I SERIOUSY DOUBT you're getting 1,000 frames per second nor even have the hardware that can do it. There's just no point to it because the human eye just can't see that. Knock that back to AT MOST 60 frames a second and you might improve your situation dramatically.
|
|
|
|

I miss discribed my situation. I dont have over 1000 Frames, my update & Draw Thread are called more then 1000 Times. But that doesn't mean it is really the Render Thread of DirectX.
So now with ur conclusion of slowing it down to 60 fps the gui is now responsive again. Easy Solution.
Side way i still ask if someone knows a way to store properties out of the WPF Thread?

Hi Folks,
I have a question about the best way to design / redesign my software. I have a program that uses a web services to perform certain tasks. Each task is a different set of request / response classes on the server end and a general function call from the Main Hook. EG.
RequestObject req = new RequestObject("SomeVal");
ResponseObject rsp = new ResponseObject();
rsp = WebServiceHook.Method1(RequestObject);
Each Method takes a different request object and returns a different type of response object.
As it stands i have a class for each of these methods, Each class has a public method Process() that does the interaction. I am trying to determine the best way to group all this code together using OO techniques without sacrificing functionality. I would like just one ProcessMethod in one class that will handle the interaction with the webservice for all the different web methods. So i would only call one ProcessMethod passing a switch of sorts that would define the relevant types and uniques strings that method requires. Some Sample code below:
[ComVisible(false)]
private static InfoRequest infoReq = null;
[ComVisible(false)]
private static InfoResponse infoRsp = null;
public static bool Process(INTERFACEREQUEST COMReq, out INTERFACERESPONSE COMRsp)
{
bool blnReturnVal = false;
CInfoRsp InfoRsp = new CInfoRsp();
CInfoReq InfoReq = (CInfoReq)COMReq;
Globals.dtStart = DateTime.Now;
Globals.Log(Logger.LogLevel.Minimum, Logger.LogType.APIMethodEntryPoint, "SOME TEXT HERE", "AND HERE", InfoReq.SalePointID);
try
{
Globals.TheService.Url = Settings.URL;
infoReq = new InfoRequest();
infoRsp = new InfoResponse();
SetRequest(InfoReq);
CallWEBServiceMethod();
SetCOMResponseValues(InfoRsp);
COMRsp = InfoRsp;
blnReturnVal = AssignCOMResponse(InfoRsp);
}
catch (Exception ee)
{
COMRsp = new CInfoRsp(ee);
blnReturnVal = false;
Globals.Log(Logger.LogLevel.All, Logger.LogType.APIMethodException, ee.ToString() + " " + ee.InnerException);
}
finally
{
InfoRsp = null;
InfoReq = null;
infoReq = null;
infoRsp = null;
GC.Collect();
}
}
Is what i am trying to achieve possible or am i trying to over engineer this solution. It currently works i just find every time i have to add a new web method call i clone one of the existing classes and change the types in the processMethod and anywhere else that's needed. This is quite tedious and prone to bugs.
Thanks In Advance

Yes.
You'd want an (abstract) base-class that defines the Process method;
public abstract bool Process(BaseProcessArgs args)
{The factory would return a class that derives from this abstract base-class, with each class having it's own implementation for the Process method. The app would only have to call the method, without knowing specific details on the class.
Varying the parameters can be done in a similar way; EventArgs is a nice example on how to vary parameters, and still have some control. Imagine a base-class for the arguments, called "BaseProcessArgs"; if you'd need to pass a string and an int, your "Args" class would look like below;
class TestArgs: BaseProcessArgs
{
public string TestString { get; set; }
public int TestInt { get; set; }
}Alternatively, if only types will change, you might want to consider a generic class.

Folks,
Question about my design so far, I am wondering if i am going about this the right way?
I have a COM Library created in C#, with COMVisible set to true. This library talks to a 3rd party WebService calling various methods depending on the task at hand. For each Request / Response class exposed by the 3rd party DLL I have a Request / Response Pair (Class and Interface) to Marshal variables specifically for a VC6 application.
Mainly using:
MarshalAs(UnmanagedType.LPStr)]
So with that in my i have added a C# project to the solution to test this code, see test method below:
static void Main(string[] args)
{
ICOMReq iReq = new CCOMReq();
ICOMRsp iRsp = new CCOMRsp();
Link l = new Link();
iReq.Date_Time = DateTime.UtcNow;
iReq.Var2 = "1023758145865";
l.DoMethod1(iReq, out iRsp);
}
The link class looks like so at the moment be but will have all the methods created once the design is correct:
public class Link
{
public bool DoMethod1(ICOMReq _COMReq, out ICOMRsp COMRsp)
{
Method1 WebServiceMethod = new Method1(new Method1Request(), new Method1Response(), (CCOMReq)_COMReq, new CCOMRsp());
WebServiceMethod.Process();
COMRsp = null;
return true;
}
}
Each DoMethod(N) that will be in the link class will look the same performing its task with identical code to the other DoMethods. The key differences between the methods is the Param Types Passed in and the Method1 (Method1Request/Method1Response) type will vary depending on the webmethod to be called.
Class Method1 (There will be one of these for every method I need to implement on the WebService) looks like so:
public class Method1 : WebServiceInterfaceBridge<Method1Request, Method1Response, ICOMReq, ICOMRsp>
{
public Method1(Method1Request WEB_Req, Method1Response WEB_Rsp, CCOMReq COM_Req, ICOMRsp COM_Rsp)
: base(WEB_Req, WEB_Rsp, CBE_Req, CBE_Rsp)
{
WEB_Req.SOME_DATE_TIME = COM_Req.Date_Time;
}
public new void Process()
{
base.Process();
}
public override void LOG()
{
Console.WriteLine(this.WebMethod_Request.MEMBER_VAR_HERE);
}
}
The class (WebServiceInterfaceBridge) that all Method(N) classes will inherit from is shown below:
public abstract class WebServiceInterfaceBridge <T,U,V,W> : WebServiceInterface
where T : class
where U : class
where V : class
where W : class
{
protected T WebMethod_Request;
protected U WebMethod_Response;
protected V COM_Request;
protected W COM_Response;
public WebServiceInterfaceBridge(T tPHSReq, U uPHSRsp, V vCBEReq, W wCBERsp)
{
WebMethod_Request = tPHSReq;
WebMethod_Response = uPHSRsp;
COM_Request = vCBEReq;
COM_Response = wCBERsp;
}
public abstract void LOG();
public void CallWebServiceMethod()
{
WebMethod_Response = CallWebMethod<T, U>(WebMethod_Request);
}
public void Process()
{
LOG();
CallWebServiceMethod();
}
}
And finally here is the class that actually calls the Web service that the WebServiceBridge Class inherits from:
public class WebServiceInterface
{
private ServiceClient WEBSVC = new ServiceClient();
public U CallWebMethod<T, U>(T tRequest)
where T:class
where U:class
{
if (tRequest.GetType() == typeof(Method2Request))
{
Method2Request Req = (Method2Request)(object)tRequest;
Method2Response Rsp = WEBSVC.Method2(Req);
return (U)(object)Rsp;
}
else if (tRequest.GetType() == typeof(Method1Request))
{
Method1Request Req = (Method1Request)(object)tRequest;
Method1Response Rsp = WEBSVC.Method1(Req);
return (U)(object)Rsp;
}
else
{
throw new NullReferenceException();
}
}
}
I have left out my internal classes for marshaling the Req/Rsp's, they are just classes with Member Vars and Get/Set's.
So basically before i carry on with my design I am wondering from an OO point of view if I am approaching this task in the right way or if what I am doing is overkill and could be greatly simplified?
TIA

Hi All,
I have used this sample as reference How to use a web cam in C# with .NET Framework 4.0 and Microsoft Expression Encoder 4[^]
and managed to modify the files to stream to my IIS . I have no issue streaming towards my own IP address . However , problem arises when i try to stream it to another IP address . It disconnected after few minutes of streaming but strangely at times it works fine(Not most of the time) . Asked at Microsoft Expression Encoder Forum and no one dares to answer me . I hope here are brave programmers here which can help me solve this particular issue . Do request me if you need to take a look at my codes .
Thanks ,
Daniel

What does this have to do with C#?? A dropped connection doesn't have anything to do with your code. Once the connection starts it's up to Encoder and the client to keep it going. Your code has nothing to do with it.

Is there a shorthand for updating an object? Something like an initializer?
var item = new FooViewModel { id = "test", name = "test" };
Something like that but instead:
Record myRecord = Context.RecordRepository.GetById(1234);
myRecord {
id = 123,
name = "blah"
}
Cheers, --EA

The best you can do is try and using LINQ to fetch and update records in the same line.
However, what you are tyring to do is not directly possible.

In VB.net its called "WITH"
C# dont have this trick... But, you can use this:
public static void With<T>(this T _object, Action<T> _action)
{
_action(_object);
}
Usage:
LongInstanceOfPersonVariableName.With(x => {
x.AgeIntVar = 21;
x.NameStrVar = "John";
x.NameStrVar += " Smith";
});
from http://stackoverflow.com/a/5964848[^]
I dont think its the best solution... But... It may work.

I have C# MDI Form EXE as a framework. In which I have to deployed my VB 6 OCX, and also calls another VB 6 OCX from displayed OCX events.
Is this possbile? where I have to make changes C# or VB 6.0?
Does anyone has made similar kind of project before?
Any link?
Thanks in Advance

It's just a COM component. You just add a reference to it and use it like any other class.
|
|
|
|
|
Thanks Dave,
fisrt COM component loaded fine in C#.net exe framework. My problem is to load another COM component into same C#.net exe framework, and this second COM component will be called from first COM component.
Hope you understand my problem.
Any idea?
|
|
|
|
|
Exactly the same as before. You add a reference to it.
You're problem is that your COM componets should not be calling into each other. That would be a hard-code tie where you couldn't use one component without the other. That's just a bad design.

I need to use a generic collection of keyvalue pair. I need thr folloeing:
1) should be generic because my values are a customized class
2) iterating should keep the order in which I added Items
3) I should be able to find the index of the element
4) I need access via Key
A dictionary is ok for 1,2,4 but not for 3
SortedList and SortedDictionary are ok for 1, 3, 4 but not for 2.
If I create a
List<keyvaluepair> it is ok for 1,2,3 but not for 4 ( I mean not directly)
SortedList<string, double> d = new SortedList<string, double>();
d.Add("z", 1);
d.Add("a", 2);
d.Add("c", 3);
d.Add("b", 4);
foreach (KeyValuePair<string,double> k in d)
{
Console.WriteLine(k.Key + " " + k.Value);
}
KeyValuePair<string, double> i_item = d.ElementAt(2);
Any suggestion?
Thanks for your time
