• Architecture Planning transactions with N-tier, distributed transactions, multiple databases

  Hi Forum I would like to know if there are some best practices for planning/documenting transactions in order to avoid deadlocks. We unfortunately have the bad habit of going into production before discovering deadlocks. The problem is that we have an N-tier architecture where developers can choose to start transactions that spans not just multiple tables but also multiple databases. So it is distributed transactions. It gets quite complex when many people implement transactions, not necessarily calling the resources in the same order. What should I as an architect do - Should I put together a document and have the developers document all transactions, including isolation level and in what order they are calling resour ...Show All

• Windows Forms Multiple radio buttons

  Can anyone help me please First of all I'm using MS VC++ 2005 Express Edition. I have multiple radio buttons in a form - in three group boxes. I have them in three group boxes as there are three choices to be made by the user on the form. The idea is that the user selects one of the choices from groupbox a, one from groupbox b and a final choice from groupbox c. Depending on the combination of the three choices different outcomes occur. Each radioButton event is handled by code in the form of: private : System::Void radioButton17_CheckedChanged(System::Object^ sender, System::EventArgs^ e) {n Variable_a = 20000; } However once a user makes a choice in the option A box all other radioButton presses are ignored ( ...Show All

• Visual Studio 2008 (Pre-release) Design Surface in CIDER

  I was willing to know what makes up the Design Surface in Cider Is it a class derived from Canvas class or Panel class or something else Also, since there is no Winforms DesignSurface equivalent here, is there a way to customize the CIDER Design Surface in the current CTP's Thanks. Nir. In our first release the design surface itself is not customizable or seperately hostable (in the way the Windows Forms design surface is). This is a long term goal but for our first release we felt that this was not as important as having the "end user" features such as snap lines in the designer or as important as being able to write design time for controls. You will be able to write design time for control ...Show All

• .NET Development Reflection - Load the dll in its domain instead of caller's domain

  Hi, I've been using reflection for quite a while but this time I need to load the dll in its own domain instead of the caller domain. So far I have not been successful. I was wondering if there's a workaround to make this happen or perhaps I should use some other techniques! Any ideas Thanks For remoting across app domains to work the object you are calling must inherit from MarshalByRefObject or be serializable. AppDomain appDomain = AppDomain.CreateDomain("DemoDomain"); DemoLib.Demo demoObj = (DemoLib.Demo)appDomain.CreateInstanceAndUnwrap("DemoLib", "DemoLib.Demo"); demoObj.DoWork(); AppDomain.Unload(AppDomain); or AppDomain appD ...Show All

• Windows Forms FlowLayoutPanel FlowDirection not working when adding controls at runtime

  I have a FlowLayout panel to which I am adding a label and linkview controls at runtime. The panel's FlowDirection property is set to TopDown. However, when I call Controls.Add on the panel at runtime, the controls are still added left to right. Why does this happen If I drag controls onto the panel at design-time, they are added top to bottom as required, it's only when adding at runtime that this happens.

• Windows Forms Sorting a treeview

  I have extended the TreeNode class to make my own class that has an extra property called 'order'. When my TreeView is initially populated new nodes are assigned a value in their order field. I've also defined my own IComparer class (TreeNodeSorter) that sorts the node based on this order property. When the Tree is populated or a new node is added at a later point then it is inserted in the right place according to the sort. However, I also want to be able to change the 'order' field of an existing node and for it to be then put in the right place. I originally tried this by updating the order field and then calling treeView1.Sort() but it didn't work. Can anyone tell me how I'd go about doing this please Thanks in advance, Tom ...Show All

• Visual Studio 'Unable to find the report in the manifest resources' - Build Action is missing??!

  Hello, I have just upgraded my VS2003 project to VS2005. Had a million things to fix, but I'm finally down to the last few. The biggest remaining problem is my Crystal Reports don't work. The error message is below... On googling it the answer seems to be I have to include the *.rpt's as an embedded resource. However, and this is the really odd bit, the properties that should show up in VS2005 to allow me to do that are simply missing! No matter how I fool around with it, there is no Build Action property when I select a file in the Solution Explorer. I notice that if I create a Windows application in VS, the Build Action property (and 3 others in the Advanced category) are available. Just not when I'm working with web projects. ...Show All
