    - Naming conventions Hello everyone, As projects get larger it becomes harder and harder to remember all of the variable names and types. I'm wondering if there is some form of naming convention out there for the C# programming language... What I'm really after are 'conventions' for variable nameing... An example is 'append List to all of your objects of type list, name all your global variables tith a '_' prepended, etc. Does such a document already exist Thanks Chris Tag: Visual C# IDE how to use code snip Visual C#

    - Converting from string to object type: difficult to explain! Hello MSDN I am having an issue with Generic functions. I am passing a generic type into a function but once I have done a few things with it I would like to type cast it to a particular type that is stored in a string. I'll show a code snippet to show the logic: Code Snippet private void task_StartTask<taskType>(string fileN) where taskType : Task { taskType task = Deserialize<taskType>(fileN); string objType = task.GetType().ToString(); /* Now we can see that objType has a string representation of task's object type. From here I would like to type cast task with it's own type so I can use methods defined specifically for that datatype like so.. */ objType.ToObject() obj = new objType.ToObject() (); // //Or using the type of the object: task.GetType() obj = (task.GetType())task; } Is this possible Many thanks!

    - structure information in WM_COPYDATA I'm trying to use WM_COPYDATA to send information from a very simple programming language to C#. I'm sending approximately 50 variables at once. What is the best way to organize these variables I've thought of two ways: -using the send function 50 times -sending 50 variables in one string and then splitting them up at delimiters. The only thing I don't like here is that the strings won't have labels. Is there any way I can structure the sending of 50 strings at once and have every string has it's own label (so that the label and not the order of the variables determines how C# catches them) Tag: Visual C# IDE how to use code snip Visual C#

    - Why I cannot see some of the methods in other classes? Hi I am a newbie in Visual Studio C# and I would like to ask you the following. I ve created two different projects the first is a Device Application and the second is a Console Application. I ve used the following code in Console Application: Code Snippet using System; using System.Collections.Generic; using System.Text; using System.Net; using System.IO; public class Test { // Specify the URL to receive the request. public static void Main(string[] args) { Uri myUri = new Uri("http://www.contoso.com"); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(myUri); // Set some reasonable limits on resources used by this request request.MaximumAutomaticRedirections = 4; request.MaximumResponseHeadersLength = 4; // Set credentials to use for this request. request.Credentials = CredentialCache.DefaultCredentials; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Console.WriteLine("Content length is {0}", response.ContentLength); Console.WriteLine("Content type is {0}", response.ContentType); // Get the stream associated with the response. Stream receiveStream = response.GetResponseStream(); // Pipes the stream to a higher level stream reader with the required encoding format. StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8); Console.WriteLine("Response stream received."); Console.WriteLine(readStream.ReadToEnd()); response.Close(); readStream.Close(); } } When I tried to do the same for the Device Application I couldn't use: request.MaximumResponseHeadersLength = 4; I got the following error: Error 1 'System.Net.HttpWebRequest' does not contain a definition for 'MaximumResponseHeadersLength' I ve checked Object Browser: System.Net.HttpWebRequest.MaximumResponseHeadersLength and the method exists. Can someone explains me what I did wrong Why I cannot use this method Thanks Tag: Visual C# IDE how to use code snip Visual C#

    - C# and VB.NET, which can be learned faster? First of all I think it is better to tell you that VB.Net & C# both uses same .net framework class library. Therefore, either C# or VB.Net does not matter very much to you. In either way you will have to use the .net framework class libraries. Now, you may ask what is the syntax of calling and using .net framework class libraries. Here, the question comes what is the syntax, VB.Net or C#. You can answer this question to yourself. Just think about your past coding experience and command over the programming languages you used in past. In my case, I started with BASIC->GW-BASIC->FOXPRO->C and VB6->C++->PHP->VB.Net and C#. I know both of them and I use both of them. If you are familier with VB or FoxPro or dBase etc. then it is better to start with VB.Net because syntax is almost same. Otherwise, I advice you to start with C#. C# is almost same as C/C++ and Java. The advantage of learning C# is not only bound within .net you can learn Java also with very little effort.

    - P/Invoke and data marshalling Oops...no it didn't. I'm having trouble getting any values out of the function. The original function doesn't return a value, rather it loaded the results into pointers that were passed as arguments. I'm not sure if the arrays that I'm passing using the [MarshalAs(...)] method you listed above are being passed purely by value or not. The code will run but I get garbage number in my "result" pointer. This is proving to be an EXTREMELY frustrating experience since all the tutorials I can find online seem to either take return values from the function itself, or do some tortured confusing process that I don't understand. I simply want to be able to pass in two int (or float) variables to the function and have them store the result. Passing them as "ref int result" doesn't seem to work. Help, anybody! This is a terrible waste of time. As always thank you. Tag: Visual C# IDE how to use code snip Visual C#

    - Unexpected % problems When I put: int p = 13; int r = (p % 10); into my code it gives me r == 3 which is what I would expect. But when I put: int p = -3; int r = (p % 10); it gives me -3!. And not 3 like I would expect and I want. I see from the MSDN examples that this is the way it should be. But why In math when you take (-3 % 10) I'm pretty sure you get 3. Just curious. And looking for a method that transforms negative values into positive. I've tried int q = [r], but that didn't work. Tag: Visual C# IDE how to use code snip Visual C#

    - keyfile instead of AssemblyKeyFile Hi I had never noticed the warning before, but looked into some of the past builds and noticed that it had always been there. After doing some research, I found out that Visual Studio 2005 now considers the use of setting the AssemblyKeyFile in the AssemblyInfo.cs file a security issue. This is due to the AssemblyKeyFile attribute being embedded within your assembly and possibly containing sensitive path information. The warning also recommended setting this information via the project settings. I use an external strong name key file for all of my assemblies. It resides outside all of my projects/solutions. When I referenced this strong name key file, VS2005 copied it into the project . This wasn't a good thing at all. http://dougrohm.com/cs/archive/2006/06/18/169.aspx and the solution http://davidkean.net/archive/2005/08/25/1162.aspx Hope this helps you out, please close the thread if it does :) Tag: Visual C# IDE how to use code snip Visual C#

    - Different between System.Type and System.RuntimeType System.Type is an abstract base class. The CLR has it's concrete implementation in the internal type System.RuntimeType. Because of this typeof(string).GetType() returns a RuntimeType but typeof(Type) returns a normal Type. Using the .Equals method does in fact an object.ReferenceEquals which returns false. To get the expecting results, you may use type.IsInstanceOfType(element). This will also return true if element is of a derived type. If you'd want to check for the exact type, the return-value of false of your method is desired result. You may also use checkType(arrayType, Type.GetType("System.RuntimeType")) to check for the RuntimeType. Tag: Visual C# IDE how to use code snip Visual C#

    - Defining Public strings Visual Web Developer I am using Visual Web Developer, it's a great product, but I'm stuck, I have done a lot of research on trying to define public strings, Examples I find are public class SData { public string sdata } This is quite logical, but the problem is using them in the code generated by Visual Web Developer using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; // I would like to define some public strings of data that // could be used thru out, but am at a lose as to where to // Place them. public partial class _Default : System.Web.UI. Page { protected void Page_Load( object sender, EventArgs e) { } protected void Button1_Click( object sender, EventArgs e) { } } Thanx for any assistance, I know it's something simple.

    - Settings File Question What I am actually doing is saving a meter address and a com port. One application is the configurator, it sets the meter address and the com port number. The second application is a calibrator tool that communicates with a motion controller through the saved com port number and communicates with HP Voltage meter through the HPIB address that was saved as well. It sounds like the xml is the way to go. Will both applications be able to read and write to the file Thanks for the info. Andy Tag: Visual C# IDE how to use code snip Visual C#

    - Object class and value data type 1) Yes, all value types implicitly inherit the class System.ValueType. a) Int32 is a ValueType b) Predefined struct is a ValueType c) User defined struct is a ValueType Your code doesn't compile because Person is a class, structs can only inherit from interfaces as they are already inheriting the special class: ValueType. So to support that C# would also have to support multiple inheritance. (Also your constructor name doesn't match the name of the struct) Tag: Visual C# IDE how to use code snip Visual C#

    - My DataSet Doesn't Work :S Hi Daniel. I think you are misunderstanding how the database explorer works. When you add a database to the database explorer, you have only added a reference to it, so that the database explorer can access that database. When you browse through the database using the database explorer, and open one of its tables, you have opened the table that is in the orginal database, if you then add data to that table, the data is added to the original database, not to your application. There are several methods of pulling that data into your application, but we will consider how it works with DataGridView (The principles remain the same across ADO.NET). When you add a DataGridView to a form, you have the opportunity to set a DataSource, you can also set this DataSource by using the .DataSource property in the property explorer. When you add your DataSource Visual Studio creates a BindingSource, a DataSet and a TableAdapter, each named with a prefix representing the name of your selected DataSource. Visual Studio also adds some code to the Load event handler of your form. The code should look a little like this : this.myTableAdapter.Fill(this.myDataSet.PubSummary); What this code does is pull the data from your database (as selected in the datasource) and fills that data into the matching Table in the DataSet, until that time the Tables in your DataSet are empty. Note that if you selected multiple tables in your .DataSource then there will be a line like the above for each Table required. One TableAdapater fills one table, so will have one for each Table, you will have one DataSet which can house any number of tables and one BindingSource which binds the DataSet to the DataGridView. If you do not have any code like : this.myTableAdapter.Fill(this.myDataSet.PubSummary); anywhere in your project (Visual Studio places it in the Load Event Handler, but you may have deleted it) then when you run your application, it never gets the data from the Database.

    - Generics - Save me from myself; Consider the following fields; The ModbusReadGroup classis part of my project, so I can change it as needed; Code Snippet ModbusReadGroup < bool > coilsReadGroup = new ModbusReadGroup < bool >(); ModbusReadGroup < bool > discreteInputsReadGroup = new ModbusReadGroup < bool >(); ModbusReadGroup < short > inputRegisterReadGroup = new ModbusReadGroup < short >(); ModbusReadGroup < short > holdingRegisterReadGroup = new ModbusReadGroup < short >(); No consider my ugly way of trying to use them; Code Snippet private void readTimer_Elapsed( object sender, System.Timers. ElapsedEventArgs e) { // Read any coils if (coilsReadGroup != null ) { bool [] _coils = new bool [coilsReadGroup.Length]; fieldTalk.readCoils(1, coilsReadGroup.StartAddress, _coils); coilsReadGroup.setValues(_coils); } // Read any discrete inputs if (discreteInputsReadGroup != null ) { bool [] _inputs = new bool [discreteInputsReadGroup.Length]; fieldTalk.readInputDiscretes(1, discreteInputsReadGroup.StartAddress, _inputs); discreteInputsReadGroup.setValues(_inputs); } // Read any input registers if (inputRegisterReadGroup != null ) { short [] _registers = new short [inputRegisterReadGroup.Length]; fieldTalk.readInputRegisters(1, inputRegisterReadGroup.StartAddress, _registers); inputRegisterReadGroup.setValues(_registers); } // Read any holding registers if (holdingRegisterReadGroup != null ) { short [] _registers = new short [holdingRegisterReadGroup.Length]; fieldTalk.readMultipleRegisters(1, holdingRegisterReadGroup.StartAddress, _registers); holdingRegisterReadGroup.setValues(_registers); } I feel like I should be able to put it all in an arraylist and do a for each, but I'm not sure what to do with the different array datatypes (short of making them objects and doing a bunch of memory sucking conversions. It seems like I should be able to define the array datatype based on the datatype used for the generic (ModbusReadGroup<>), but I'm not having luck with that. Any ideas Thanks Tag: Visual C# IDE how to use code snip Visual C#
