• Windows Forms COMBOBOX VS DATAGRIDVIEW - resizing and positioning!

  Hi! I have both combo boxes and datagridview on the same form. Combos are not inside the datagrid. They are outside On the top of datagrid aligned in a horizontal line. Each combo is aligned with its own column from datagridview. But... When I resize (to the right) let's say column 3 the combo which is positioned with column 4 doesn't move right as it should. I found out how to resize a single combo if a single column resizes, ...Show All

• Visual Studio 2008 (Pre-release) Missing ORM Features

  Hi, Been playing with the preview and saw in the doco that mapping inheritence is not supported. This is fundamental to an ORM. Without it polymorphic queries are not possible. Not only this, but all ORMs I've worked with (Persistence, TopLink, Versant, Hibernate, NHibernate)  support the standard 3 ways of mapping inheritence to a relational model. This is equally important because alot of legacy schemas out there use a combination of the ...Show All

• Visual Basic How to keep a control Loaded

  I have a TabControl and it has three tabs. When I click between these tabs all the controls in the clicked tab are reloaded. This makes the program seem like it lags. I have seen other program that contain more tabs and even more controls but the tab transition is flawless. I think it's kind of ridiculous that some of my controls even reload at all; like my labels. None of the properties for my labels ever change so they don't need to be loaded ...Show All

• Visual Studio Team System "AvoidNamespacesWithFewTypes" in Code Analysis

  The help on this topics indicates that the casue for this warning is: "A namespace other than the global namespace contains fewer than five types." I get such a warning in a namespace that has 11 types defined in it (10 classes and one interface).

• Visual C++ Software controlling mouse in WinXP

  Hi, I've been trying to write a program in VC++ .NET which controls mouse movement in WinXP. Sadly I'm a little lost as to how I should achieve this. All I want to be able to do is to set the position of the mouse cursor to an arbitrary place on the screen. I was hoping there was a straight forward system call I could use to fake a mouse interrupt, but I haven't had much luck finding that. Does anyone know how this is done, or if the approach is ...Show All

• Software Development for Windows Vista Workflow compiler error: "Attribute 'Class' not found on the root activity."

  I have a console app that programmatically builds a workflow. It creates a sequential workflow object, adds activities (implemented in a separate DLL) to it, serializes the generated workflow definition to a XOML file,  compiles the XOML definition to an assembly (DLL), and executes the workflow (we are building a prototype here, so at this point everything is done within one program). It seems to work, but there is one ...Show All
