    - accessing web references in .dll from windows applications...when running in Visual Studio .Net Hi, We have an windows application that includes some .dll files. These .dll files have dynamic web references included in them. When I run the application from it's install folder, the web references work okay fine (they are read from the "application.exe.config" file. But when running the application from within Visual Studio .Net, we have to change the value of the web reference with the project in order for it to work (ie. it does not read the app.config or web.config files, uses the value in the web reference). I have used the same "application.exe.config" file in the bin directory of the project, does not seem to read from it. I have changed all the app.config and web.config files in the project directories....still no good. Only seems to use the properties value in the web reference in each project (which are the source for the .dll files). While it is fine that it works at run time, not working running via Visual Studio requires that we change the web refences in the projects if we want to change the values...rather than just changing a config file value. Any help would be appreciated. Tag: Visual C# General Threading question. Is this possible? Visual C#

    - Windows client tutorial (start to finish) I'm looking for a book or a web-totorial describing the development of a databasedriven windows application from start to end. It should describe in a step by step way how a windows client application is created. It doesn't need to be a huge, super complex application, just enought to cover frequent situations. I would like to use it in order to better understand how I should devide a 'standard application' into modules and layers. Most books talking about the subject gets pretty abstract, so I'm looking for a working example using good patterns and practises. I have just started looking at the 'Starter kits' from Microsoft, but I'm not sure yet if it is exactly what I'm looking for... Does anyone have any good suggestions here regards Andreas Tag: Visual C# General Threading question. Is this possible? Visual C#

    - Deriving from a hierarchy of abstract classes Hi there, I'm designing a system in which I have an abstract class that hosts properties that point to instances of abstract classes as well, so I have a hierarchy of abstract classes. Let's say I have a base class Vehicle , with a property named Properties of the abstract type VehicleProperties . Now, I have a Car class that derives from Vehicle . I derive CarProperties from VehicleProperties ... Ok, fine, but now when I program against the deriven Car class, I would like to see Car.Properties as CarProperties , not as VehicleProperties . Of course I can do that by hiding: public new VehicleProperties Properties{ get { return (VehicleProperties)this._properties; } } But is this the preferred way Anyone Marc Tag: Visual C# General Threading question.

    - C# User Input I have been into C++ for a few months and got up to learning functions, pointers, references, and a little OOP. I wanted to experiment with C#, for many personal reasons. It seems to attract me more.. With C++ all you have to do is.. cout << "Enter a num"; cin >> num; Now, in C# I don't know how to get a user input for a number.The Console.ReadLine() only does strings I believe. And I remember using something else..but when I entered '4' it output '52', input '5' i get '53'. Thats probably the ASCII codes How can I just get it to output the number An example of a "guess my number" program would be much appreciated Marky03 Tag: Visual C# General Threading question.

    - Simple binding to Datarow - values don't update??? Hi, I have a loop that is populating label controls from a Datatable. If I simple bind the datarow to the labels' Text property, when I update the Datatable I expected the changes to be reflected in the label. This is true if I bind the the table directly. // this shows the correct values but they don't update when I update the data in the table ... templabel.DataBindings.Add("Text", dt.Rows[i ] , "state"); ... // when I bind directly to the table, updating the table does reflect the changes. But this option is no good as all my label controls have the same values. ... templabel.DataBindings.Add("Text", dt , "state"); ... What I'm trying to achieve, is when I update the data in the table the changes are reflected automatically in the bound controls. Tag: Visual C# General Threading question. Is this possible?

    - Settings File Question You will need to create xml configuration file in order to have one common setting file. But i think that this can be avoided as a need if you change your application's design. What i mean by that is that if you need some common thing, then that could be placed in separate library that will be used by both applications. Again you will have xml configuration file. I will describe it in a scenario. Imagine you have data access layer which needs connection settings. If you place this data layer that needs that connection properties in applications, which both use same connection, than solution is to move all source for data layer in separate assembly and both applications will use same assembly for accessing database, using same connection properties. And it's common way of storring assembly configurable variables in xml config file. Tag: Visual C# General Threading question. Is this possible? Visual C#

    - Destroying objects You don't have any control over when your C# destructor (finalizer) is called anyhow, so it's usefulness is almost nil. Also, the book you read should have said to implement IDisposable, create a Dispose method to get rid of your unmanaged resources. E.g.: private bool _disposed = false; public Dispose() { Dispose(true); GC.SuppresFinalize(this); } protected virtual void Dispose(bool disposing) { if (_disposed) return; if (disposing) // Do clean-up _disposed = true; } You don't really need a finalizer. Additionally, if the clean-up stuff makes calling other methods invalid, use the _disposed member variable to determine if the object has disposed and throw ObjectDisposedException if so. C# destructors (finalizers) are difficult to write because any reference you have may be invalid in the finalizer since the calls to finalizers is not guaranteed to be in any kind of order. Best to just avoid it and implement the dispose pattern. Tag: Visual C# General Threading question. Is this possible? Visual C#

    - Identifying public methods and user defined methods with in a class file HI, I am in the process of developing a generic tool (Code Checker) in .net framework 2.0. The application will check the input file whether it has followed the mentioned coding standard (Method name, variable names should be wither in camel casing or pascal casing) guidelines. Can any one explain me how to get or identify user defined method names from a file given as input. Short description The application will get a file (vb or cs) as input and will look for the coding standard which should be checked (available in the config file). The application should read the file and identify the public methods with events, user defined methods, variables and constants. The application will parse the text file and give a detailed report to the end user showing the lines which have voilated the coding standard rules (comapring the method names using string comaprison with case sensitive option) Also can any one give me some inputs on how to develop this solution. If this tool is developed then it will save enormous time to the developers on checking the coding standards before submitting their code to the clients or for auditing Tag: Visual C# General Threading question.

    - Class injection / Renaming a class / adding Property ?? Hi Sunstar, Though it is not possible to inject a class as you desire because the TextBox class is a compiled class and cannot be modified. If your intension is to write some functions which are available in each of the classes that inherit from the TextBoxBase class then you may want to have a look at the extension methods in C# 3.0. Extension methods lets you add functionality to a type that you cannot modify or may not want to modify.

I am working with some 3rd party software and it has limitations, so let me know if this this possible in C#

forgive me as i am new to DLLs, etc. and might use the wrong terminology or have the wrong concepts in my mind.

I need to have a DLL called "parent" start a thread or even an executable called "child".

the problem is that the when the DLL function terminates, i dont know how I will have a handle to the child application.

i need to issue commands to this child program.

im thinking the child could be a daemon type program and i would communicate to it via sending messages through a port.

id rather now...but i am new to the .NET world and cannot think of any other way. is there a way to get the PID and somehow talk to it that way

Thanks

Re: Visual C# General Threading question. Is this possible?

Ðãv? S. Â???????

Create a method in the parent module that returns the handle. The method would be called from a child module to receive the handle.

If you are looking for two separate processes, you can also start a process and use IPC channel (available with remoting and also WCF) to communicate. Let me know if you need more infor on this.

Re: Visual C# General Threading question. Is this possible?

clam61

nice! IPC channel seems like the way to go...ill try it out and let me know if you have any problems. thanks!
