Use VersionControlExt.Explorer outside Visual Studio

- by Ian

Hi All, I'm developing a TFS tool to assist the developers in our company. This said tool needs to be able to "browse" the TFS server like in the Source Control Explorer. I believe that by using VersionControlExt.Explorer.SelectedItems, a UI will pop-up that will enable the user to browse the TFS server (please correct me if I'm wrong). However, VersionControlExt is only accessible when developing inside Visual Studio (aka Plugin). Unfortunately, I am developing a Windows Application that won;t run inside VS. So the question is, Can I use VersionControlExt outside of Visual Studio? If yes, how? Here's an attempt on using the Changset Details Dialog outside of Visual Studio string path = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); Assembly vcControls = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Controls.dll"); Assembly vcClient = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Client.dll"); Type dialogChangesetDetailsType = vcControls.GetType("Microsoft.TeamFoundation.VersionControl.Controls.DialogChangesetDetails",true); Type[] ctorTypes = new Type[3] {vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.VersionControlSever"), vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.Changeset"), typeof(System.Boolean)}; ConstructorInfo ctorInfo = dialogChangesetDetailsType.GetConstructor(ctorTypes); Object[] ctorObjects = new Object[3] {VersionControlHelper.CurrentVersionControlServer, uc.ChangeSet, true}; Object oDialog = ctorInfo.Invoke(ctorObjects); dialogChangesetDetailsType.InvokeMember("ShowDialog", BindingFlags.InvokeMethod, null, oDialog, null);

Implicit and Explicit implementations for Multiple Interface inheritance

Following C#.NET demo explains you all the scenarios for implementation of Interface methods to classes. There are two ways you can implement a interface method to a class. 1. Implicit Implementation 2. Explicit Implementation. Please go though the sample. using System; namespace ImpExpTest { class Program { static void Main(string[] args) { C o3 = new C(); Console.WriteLine(o3.fu()); I1 o1 = new C(); Console.WriteLine(o1.fu()); I2 o2 = new C(); Console.WriteLine(o2.fu()); var o4 = new C(); //var is considered as C Console.WriteLine(o4.fu()); var o5 = (I1)new C(); //var is considered as I1 Console.WriteLine(o5.fu()); var o6 = (I2)new C(); //var is considered as I2 Console.WriteLine(o6.fu()); D o7 = new D(); Console.WriteLine(o7.fu()); I1 o8 = new D(); Console.WriteLine(o8.fu()); I2 o9 = new D(); Console.WriteLine(o9.fu()); } } interface I1 { string fu(); } interface I2 { string fu(); } class C : I1, I2 { #region Imicitly Defined I1 Members public string fu() { return "Hello C"; } #endregion Imicitly Defined I1 Members #region Explicitly Defined I1 Members string I1.fu() { return "Hello from I1"; } #endregion Explicitly Defined I1 Members #region Explicitly Defined I2 Members string I2.fu() { return "Hello from I2"; } #endregion Explicitly Defined I2 Members } class D : C { #region Imicitly Defined I1 Members public string fu() { return "Hello from D"; } #endregion Imicitly Defined I1 Members } }.csharpcode, .csharpcode pre{ font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/}.csharpcode pre { margin: 0em; }.csharpcode .rem { color: #008000; }.csharpcode .kwrd { color: #0000ff; }.csharpcode .str { color: #006080; }.csharpcode .op { color: #0000c0; }.csharpcode .preproc { color: #cc6633; }.csharpcode .asp { background-color: #ffff00; }.csharpcode .html { color: #800000; }.csharpcode .attr { color: #ff0000; }.csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em;}.csharpcode .lnum { color: #606060; }Output:-Hello C Hello from I1 Hello from I2 Hello C Hello from I1 Hello from I2 Hello from D Hello from I1 Hello from I2 span.fullpost {display:none;}

Accessing Bluetooth virtual COM port on Windows without manual pairing

- by oo_olo_oo

I need to connect to a Bluetooth device through virtual COM port created in Windows. It's easy when the port has been already created during manual pairing procedure. But I would like my application to relieve an user from the manual pairing of a device. I would like to present all devices in the range, allow user to chose one, and then create virtual COM port connected with the selected device. I'm not trying to avoid the pairing procedure itself, but rather I would like to invoke it by my application. I started getting familiar with Microsoft Bluetooth API. And then some doubts arose. I've been wondering what happen if some user would use different (than Microsoft's) Bluetooth stack? Is the Microsoft's API the real Bluetooth API, which have to be implemented by any other Bluetooth stack provider? Or rather each provider has its own API, and the Microsoft's is only one of many other?

How to make QCombobox painting item delegate for it's current Item? (Qt 4)

- by r4nj33t

QCombobox set Item delegate not painting for current Item.. I am trying to create a combo box showing different line types (Solid, Dotted, Dash etc). Currently i am setting item delegate for its content so as to draw/paint line type instead of displaying names. All line types are drawing currectly but as soon as i am selecting any line type from the combobox, the current index of combo box is displaying just the line name and not painting it. How can i make it paint the selected line type on the current combo box index?

Improve your Application Performance with .NET Framework 4.0

Nice Article on CodeGuru. This processors we use today are quite different from those of just a few years ago, as most processors today provide multiple cores and/or multiple threads. With multiple cores and/or threads we need to change how we tackle problems in code. Yes we can still continue to write code to perform an action in a top down fashion to complete a task. This apprach will continue to work; however, you are not taking advantage of the extra processing power available. The best way to take advantage of the extra cores prior to .NET Framework 4.0 was to create threads and/or utilize the ThreadPool. For many developers utilizing Threads or the ThreadPool can be a little daunting. The .NET 4.0 Framework drastically simplified the process of utilizing the extra processing power through the Task Parallel Library (TPL). This article talks following topics “Data Parallelism”, “Parallel LINQ (PLINQ)” and “Task Parallelism”. span.fullpost {display:none;}

Using LINQ Lambda Expressions to Design Customizable Generic Components

LINQ makes code easier to write and maintain by abstracting the data source. It provides a uniform way to handle widely diverse data structures within an application. LINQ’s Lambda syntax is clever enough to even allow you to create generic building blocks with hooks, into which you can inject arbitrary functions. Michael Sorens explains, and demonstrates with examples. span.fullpost {display:none;}

pass username and password to get-credential or run sql query without using invoke-sqlcmd in Powersh

- by Emo

I am trying to connect to a remote sql database and simply run the "select @@servername" query in Powershell. I'm trying to do this without using integrated security. I've been struggling with "get-credential" and "invoke-sqlcmd", only to find (I think), that you can't pass the password from "get-credential" to another Powershell cmdlets. Here's the code I'm using: add-pssnapin sqlserverprovidersnapin100 add-pssnapin sqlservercmdletsnapin100 load assemblies [Reflection.Assembly]::Load("Microsoft.SqlServer.Smo, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91") [Reflection.Assembly]::Load("Microsoft.SqlServer.SqlEnum, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91") [Reflection.Assembly]::Load("Microsoft.SqlServer.SmoEnum, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91") [Reflection.Assembly]::Load("Microsoft.SqlServer.ConnectionInfo, Version=9.0.242.0, Culture=neutral,PublicKeyToken=89845dcd8080cc91") connect to SQL Server $serverName = "HLSQLSRV03" $server = New-Object -typeName Microsoft.SqlServer.Management.Smo.Server -argumentList $serverName login using SQL authentication $server.ConnectionContext.LoginSecure=$false; $credential = Get-Credential $userName = $credential.UserName -replace("\","") $pass = $credential.Password $server.ConnectionContext.set_Login($userName) $server.ConnectionContext.set_SecurePassword($credential.Password) $DB = "Master" invoke-sqlcmd -query "select @@Servername" -database $DB -serverinstance $servername -username $username -password $pass If if just hardcode the password in at the end of the "invoke-sqlcmd" line, it works. Is this because you can't use "get-credential" with "invoke-sqlcmd"? If so...what are my alternatives? Thanks so much for you help Emo

Advantages of Singleton Class over Static Class?

Point 1)Singleton We can get the object of singleton and then pass to other methods.Static Class We can not pass static class to other methods as we pass objectsPoint 2) Singleton In future, it is easy to change the logic of of creating objects to some pooling mechanism. Static Class Very difficult to implement some pooling logic in case of static class. We would need to make that class as non-static and then make all the methods non-static methods, So entire your code needs to be changed.Point3:) Singleton Can Singletone class be inherited to subclass? Singleton class does not say any restriction of Inheritence. So we should be able to do this as long as subclass is also inheritence.There's nothing fundamentally wrong with subclassing a class that is intended to be a singleton. There are many reasons you might want to do it. and there are many ways to accomplish it. It depends on language you use.Static Class We can not inherit Static class to another Static class in C#. Think about it this way: you access static members via type name, like this: MyStaticType.MyStaticMember(); Were you to inherit from that class, you would have to access it via the new type name: MyNewType.MyStaticMember(); Thus, the new item bears no relationships to the original when used in code. There would be no way to take advantage of any inheritance relationship for things like polymorphism. span.fullpost {display:none;}

Error mounting CloudDrive snapshot in Azure

- by Dave

Hi, I've been running a cloud drive snapshot in dev for a while now with no probs. I'm now trying to get this working in Azure. I can't for the life of me get it to work. This is my latest error: Microsoft.WindowsAzure.Storage.CloudDriveException: Unknown Error HRESULT=D000000D ---> Microsoft.Window.CloudDrive.Interop.InteropCloudDriveException: Exception of type 'Microsoft.WindowsAzure.CloudDrive.Interop.InteropCloudDriveException' was thrown. at ThrowIfFailed(UInt32 hr) at Microsoft.WindowsAzure.CloudDrive.Interop.InteropCloudDrive.Mount(String url, SignatureCallBack sign, String mount, Int32 cacheSize, UInt32 flags) at Microsoft.WindowsAzure.StorageClient.CloudDrive.Mount(Int32 cacheSize, DriveMountOptions options) Any idea what is causing this? I'm running both the WorkerRole and Storage in Azure so it's nothing to do with the dev simulation environment disconnect. This is my code to mount the snapshot: CloudDrive.InitializeCache(localPath.TrimEnd('\\'), size); var container = _blobStorage.GetContainerReference(containerName); var blob = container.GetPageBlobReference(driveName); CloudDrive cloudDrive = _cloudStorageAccount.CreateCloudDrive(blob.Uri.AbsoluteUri); string snapshotUri; try { snapshotUri = cloudDrive.Snapshot().AbsoluteUri; Log.Info("CloudDrive Snapshot = '{0}'", snapshotUri); } catch (Exception ex) { throw new InvalidCloudDriveException(string.Format( "An exception has been thrown trying to create the CloudDrive '{0}'. This may be because it doesn't exist.", cloudDrive.Uri.AbsoluteUri), ex); } cloudDrive = _cloudStorageAccount.CreateCloudDrive(snapshotUri); Log.Info("CloudDrive created: {0}", snapshotUri, cloudDrive); string driveLetter = cloudDrive.Mount(size, DriveMountOptions.None); The .Mount() method at the end is what's now failing. Please help as this has me royally stumped! Thanks in advance. Dave

Avoid painting over nested controls

- by Cobus Kruger

I am writing a toolbar-style control and use the ThemeServices unit to paint the background required by the toolbar. Like so: ThemeServices.DrawElement(Canvas.Handle, ThemeServices.GetElementDetails(trRebarRoot), ARect); I then drop child controls onto the toolbar and voila - instant toolbar. Except that every now and again I notice that the nested (child) controls don't repaint as well. So my control paints its background and the child controls disappear until you move the mouse over them. Some of the edit controls show their client area (no border) and some of them are just gone altogether. This happens mostly when I place a window from another application over the toolbar and move it away. I keep thinking this has to be very easy to cure, that perhaps I'm somehow preventing the paint message from reaching the child controls, or missing an override but I have been unable to figure it out.

Please Cancel to stay on page or OK to continue "); if (conf) { clearDirty(); return true; } else { var e = window.event; e.cancelBubble = true; if (e.stopPropagation) e.stopPropagation(); return false; } } else return true; } document.body.onclick = setControlChange; document.body.onkeyup = setControlChange; var onBeforeUnloadFired = false; // Function to reset the above flag. function resetOnBeforeUnloadFired() { onBeforeUnloadFired = false; } function doBeforeUnload() { var hf = document.getElementById("<%=hfIsDirty.ClientID%>"); // If this function has not been run before... if (!onBeforeUnloadFired) { // Prevent this function from being run twice in succession. onBeforeUnloadFired = true; // If the form is dirty... if (hf.value == "1") { event.returnValue = "If you continue you will lose any changes that you have made to this record."; } } window.setTimeout("resetOnBeforeUnloadFired()", 1000); } if (window.body) { window.body.onbeforeunload = doBeforeUnload; } else window.onbeforeunload = doBeforeUnload; </script> Step 3: Here is how the tabcontrol should look like <asp:UpdatePanel ID="upTab" runat="server" UpdateMode="conditional"> <ContentTemplate> <ajaxtoolkit:TabContainer ID="tcBaseline" runat="server" Height="400px" OnClientActiveTabChanged="ActiveTabChanged"> <ajaxtoolkit:TabPanel ID="tpPersonalInformation" runat="server"> <HeaderTemplate> <asp:Label ID="lblPITab" runat="server" Text="<%$ Resources:Resources, Baseline_Tab_PersonalInformation %>" onclick="checkDirty();"></asp:Label> </HeaderTemplate> <ContentTemplate> <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder> </ContentTemplate> </ajaxtoolkit:TabPanel> span.fullpost {display:none;}

Improve your Application Performance with .NET Framework 4.0

Nice Article on CodeGuru. This processors we use today are quite different from those of just a few years ago, as most processors today provide multiple cores and/or multiple threads. With multiple cores and/or threads we need to change how we tackle problems in code. Yes we can still continue to write code to perform an action in a top down fashion to complete a task. This apprach will continue to work; however, you are not taking advantage of the extra processing power available. The best way to take advantage of the extra cores prior to .NET Framework 4.0 was to create threads and/or utilize the ThreadPool. For many developers utilizing Threads or the ThreadPool can be a little daunting. The .NET 4.0 Framework drastically simplified the process of utilizing the extra processing power through the Task Parallel Library (TPL). This article talks following topics “Data Parallelism”, “Parallel LINQ (PLINQ)” and “Task Parallelism”. span.fullpost {display:none;}

VS2010 Load Testing - Restricting ports

- by marks-s

HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\VisualStudio\10.0\EnterpriseTools\QualityTools\ListenPortRange\PortRangeStart HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\VisualStudio\10.0\EnterpriseTools\QualityTools\ListenPortRange\PortRangeEnd I've set these keys on the client as described but according to netstat the client is still listening on random ports. The controller is attempting to communicate on the same random ports as the client. Anyone experienced the same?
