  • Creating a class Hierarchy for Atoms,neutrons,protons,chemical reationc

    - by Smart Zulu
    I need help to create a program that can show the hierarchy of any Atoms and its components (neutrons,protons,electrons,and chemical reaction) Here is a code of what i have done so far,being a novice at the subject using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Atoms { public class Atoms { protected string name = "Sodium"; protected string element ="Metal"; public virtual void GetInfo() { Console.WriteLine("name: {0}",name); Console.WriteLine("element: {0}", element); } } class Proton : Atoms { public int number = 11 ; public override void GetInfo() { base.GetInfo(); Console.WriteLine("Proton number: {0}",number); } } class Electron : Atoms { public int number = 11; public override void GetInfo() { base.GetInfo(); Console.WriteLine("Electron number: {0}", number); } class Neutrons : Atoms { public int number = 12; public override void GetInfo() { base.GetInfo(); Console.WriteLine("Neutron number: {0}", number); } class TestClass { static void Main() { Proton P = new Proton(); P.GetInfo(); Neutrons N = new Neutrons(); N.GetInfo(); Electron E = new Electron(); E.GetInfo(); Console.WriteLine("click any key to exit"); Console.ReadLine(); } } } } }

    - by Chris
    Hi, I'm working on an old site that needs to be optimised, I've installed Refactor! and its coming up with lots of recommendations, including lots of instances where objects aren't disposed off. Is there a way to create a report of these recommendations or another tool that I could use? Thanks, Chris.

  • How can I add array data in winform datagridview?

    - by Phsika
    I generated Personel[] type array from Biz.Bal.GetPersonelById("1") but if I want to add winforms, I do that like below. Is there any simple method? Like GridView.dataSource=myArray? private void Form1_Load(object sender, EventArgs e) { Form_init(); Model.Personel[] list = new Model.Personel[0]; list = Biz.BAL.GetPersonelByID("1"); dataGridView1.Rows[0].Cells[0].Value = list[0].ID; dataGridView1.Rows[0].Cells[1].Value = list[0].Ad; dataGridView1.Rows[0].Cells[2].Value = list[0].SoyAd; dataGridView1.Rows[0].Cells[3].Value = list[0].Maas; dataGridView1.Rows[0].Cells[4].Value = list[0].Departman; }

  • A RenderTargetView cannot be created from a NULL Resource

    - by numerical25

  • .odx Files in BizTalk 2009 (VS2008 IDE) Fail to open. "Unspecified Error"

    - by AllenG
    Okay, I'm not sure if this is an SO question, or a ServerFault question, but I figured I'd post here first. I have a BizTalk project which works like a champ for its original design. It's been deployed and it's working fine. Today, I went in to add some new fuctionality by modifying one of my orchestrations. When I attempted to open it, I got a message which simply stated: "The operation could not be completed. Unspecified error." I've closed the IDE and re-opened; I've restarted the machine; I've even allowed Microsoft Updates to run and restart the machine. Everything else opens just fine (.xsd files, .btms, etc.) so it appears only to be the orchestrations which are failing. Has anyone ever encountered a similar issue and resolved it (short of reinstalling BizTalk/VS, or blowing the orchs away and rebuilding)? Any help would be appreciated.

  • simple blog engine for website

    - by Alexander
    I know that there's a lot of free open source blog engine out there such as BlogEngine.NET. However that's an overkill for my purpose... I so far has created my own simple one by storing posts in a .xml file and so every time the main page loads it reads from all those xml files and displays it as posts. Now my problem is when a user clicks on a post title I want it to show on a new page(.aspx), so if the title is X then I want a new page called X.aspx when the user clicks on the title on the homepage. I hope this makes sense. My question is how do I create such thing?

  • ATL OR C# for windows shell/namespace extenssion?

    - by _Avishay_
    Hi, i have a question, after allot of hours in googling and reading articles, i understood that namespace extenssion in windows is quite tricky (In C++ at least), now i've also seen its possible to do so in C# , but microsft does'nt officaly confirms using .net for namespace extensions... though i have seen very nice commercial Namespace Extenssion framework , but none is free.... so to my question :) , i want to develop my own Namespace Extenssion ,i have C++/C# knwoledge and basic COM/ATL , but if it can be done i prefer c#, so does c# inteop can fully do the work without too many tricks ? or one shall go diving in the ATL to create the neccessary COM objects... and another question , can i program to Windows O/S with C# anything that can be done in C++/ATL/MFC ? thanks!

  • HTTP Error 403.1 - Permissions are fixed, what else is wrong?

    - by baron
    I have developed a HTTP Handler Web Service, and have had it successfully deployed, through testing on other environments i've ran into another problem. This is the error message I receive: You have attempted to execute a CGI, ISAPI, or other executable program from a directory that does not allow programs to be executed. HTTP Error 403.1 - Forbidden: Execute access is denied. Internet Information Services (IIS) So it is obvious what needs to be fixed, so: 1) Start Internet Information Services (IIS) Manager. 2) Right-click the Web site that contains the SharePoint Web site that you created, and then click Properties. 3) Click the Home Directory tab. 4) Under Application settings, click either Scripts only in the Execute permissions list or Scripts and Executables in the Execute permissions list (as appropriate to your situation). Click OK. 5) Quit IIS Manager. But I'm still getting the same error. So what else could be wrong?

  • razor intellisense not working on VS2010 for microsoft.web.helpers

    - by pomarc
    I have VS2010 Premium,.NET4.0, MVC3 Tools Update. I've nugetted microsoft-web-helpers successfully. I cannot get @razor intellisense to recognize the microsoft.web.helpers classes. They do work correctely at runtime, i.e. @Twitter.profile shows a profile, but at design time the statent is seen as an error and no members are shown after "." I've tried to add <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> to the <assemblies> element in web.config, but it didn't help. Any idea? thanks.

  • web.config transforms not being applied on either publish or build installation package

    - by BenA
    Today I started playing with the web.config transforms in VS 2010. To begin with, I attempted the same hello world example that features in a lot of the blog posts on this topic - updating a connection string. I created the minimal example shown below (and similar to the one found in this blog). The problem is that whenever I do a right-click - "Publish", or a right-click - "Build Deployment Package" on the .csproj file, I'm not getting the correct output. Rather than a transformed web.config, I'm getting no web.config, and instead the two transform files are included. What am I doing wrong? Any help gratefully received! Web.config: <?xml version="1.0"?> <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <connectionStrings> <add name="ConnectionString" connectionString="server=(local); initial catalog=myDB; user=xxxx;password=xxxx" providerName="System.Data.SqlClient"/> </connectionStrings> </configuration> Web.debug.config: <?xml version="1.0"?> <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <connectionStrings> <add name="ConnectionString" connectionString="server=DebugServer; initial catalog=myDB; user=xxxx;password=xxxx" providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/> </connectionStrings> </configuration> Web.release.config: <?xml version="1.0"?> <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <connectionStrings> <add name="ConnectionString" connectionString="server=ReleaseServer; initial catalog=myDB; user=xxxx;password=xxxx" providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/> </connectionStrings> </configuration>

  • Changing styling of DataGridViewComboBoxCell from DropDownList to DropDown?

    - by John at CashCommons
    (This question is narrower in scope than this question I asked earlier.) Say I have a DataGridViewComboBoxColumn, and want to switch the style of the ComboBox control between DropDownList and DropDown (mainly for the text field editing capability). I'd like to do this on a row-by-row basis (at the DataGridViewComboBoxCell level). How would I do that programatically? Or maybe a different way of asking: How do I access the ComboBox control given an object of type DataGridViewComboBoxCell? (I'm in VB 2005.) Thanks as always.

  • Log4cxx sample program and steps to compile

    - by Jake
    Hi guys Hoping someone can help out.. I've been scouring the net for a simple how-to to get a good log4cxx program working, with steps on setting up the libraries, dependants, directives, library paths etc etc.. as of yet i've found a lot of valuable but disjointed information.. trying to pull it all together has been a bit of a nightmare, so i'm reaching out and wondering if any kind soul knows of, or could put together a simple how-to, to get a standard win32 console app running with either static or dynamically linked release mode log4cxx.. I have win32 binary releases of the libraries, and thanks to a very cool dude from "Must a blog have a name" I have a win32 project which can build log4cxx.. i just cant bloody use it :) It would be really helpful to me, and probably to others, to be able to refer to something like this and not 20 different pages, with different lists of libraries needed to download and install.. :) Here's hoping Thanks guys J

  • How to share WinForms and code between 2 projects

    - by Richard Bysouth
    Hi I have a working Windows Forms app (split into an EXE and a few DLLs). Now I've been asked to look at creating another app (MyAppLite) that has only a very small subset of the functionality. Think of it as similar to MS Word Viewer vs. MS Word. Everything that I need to build MyAppLite is contained in the main solution - essentially I need to use a couple of the WinForms and whatever bits in the DLLs they call into. What would be the best way to do this? I was thinking of creating another Project in my solution for MyAppLite, then adding the necessary source files as links (using Add Existing Item Add As Link in Solution Explorer). I definitely wouldn't want to maintain 2 copies of the source code. FYI it's a .NET 2.0 VB app, using VS2008. thanks Richard

  • MS Access 2003 - Save button enabling on form open on different tabs

    - by Justin
    I have a tab control on a form, and a couple different tabs have save buttons on them. Once the user saves data (via SQL statements in VBA), I set the .enabled = false so that they cannot use this button again until moving to a brand new record (which is a button click on the overall form). so when my form open i was going to reference a sub that enabled all these save buttons because the open event would mean new record. though i get an error that says it either does not exist, or is closed. any ideas? thanks EDIT: Sub Example() error handling Dim db as dao.database dim rs as dao.recordset dim sql as string SQL = "INSERT INTO tblMain (Name, Address, CITY) VALUES (" if not isnull (me.name) then sql = sql & """" & me.name & """," else sql = sql & " NULL," end if if not insull(me.adress) then sql = sql & " """ & me.address & """," else sql = sql & " NULL," end if if not isnull(me.city) then sql = sql & " """ & me.city & """," else sql = sql & " NULL," end if 'debug.print(sql) set db = currentdb db.execute (sql) MsgBox "Changes were successfully saved" me.MyTabCtl.Pages.Item("SecondPage").setfocus me.cmdSaveInfo.enabled = false and then on then the cmdSave needs to get re enabled on a new record (which by the way, this form is unbound), so it all happens when the form is re-opened. I tried this: Sub Form_Open() me.cmdSaveInfo.enabled = true End Sub and this is where I get the error stated above. So this is also not the tab that has focus when the form opens. Is that why I get this error? I cannot enable or disable a control when the tab is not showing?

  • changing ASP.NET tag formatting

    - by Steven
    When I drag a Label control to my document, I get the following code : <asp:Label ID="Label1" runat="server" text="Label"></asp:Label> I prefer my code to look like the following instead : <asp:Label ID="Label1" runat="server" Text="Label" /> How can I get .NET to do this by default? I looked in Tools - Options - Text Editor, where you'd expect to find it, but I couldn't find anything relevant there.

  • VS2008 - Find and Replace - Searches too many files.

    - by Pam Bullock
    I've used VS2008 a lot and have never had this problem. However, I started a new job and am using a new machine. Ever since I've gotten here the VS Find feature has been acting funny. I first noticed it when I did a replace all for "All Open Files". The project wouldn't build because the values had actually been replaced in other files within the solution that were not open and didn't even open after I pressed replace all. I have found that I can never use replace all on this machine because I never know what it is going to do. Even if I just do a find on "Current Document", once it's done with the document and I should get that message that says "No more matches found" it actually OPENS another random file from my solution where there is a match and keeps on going. It seems to never make any difference what "Look in" option I've chosen. My coworker has an install off the same disk and claims to not be experiencing this. We're in the middle of a stressful, huge project with a close deadline so I know my boss won't let me do a reinstall. Has anyone else ever had this happen? Anyone know a fix?? Thanks, Pam

  • Problem running ASP.NET MVC 2 website on IIS7

    - by Charlie
    I'm trying to deploy my ASP.NET MVC 2 website from VS2010 beta 2 to IIS7. The publish works fine but none of the routes work, so when I go to the URL http://localhost/myapp/Home/Index I get the error: HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I'm deploying to a virtual directory which is using an app pool configured for the .NET 4 framework with managed pipeline mode set to integrated. Also, if I go Basic Settings-Test Connection, both tests pass. From what I understand, it should just work? I don't have any problems deploying Nerd Dinner from VS2008, that works fine.
