• Windows Forms Custom Control With SelectedValue Property - How to determine correct "default" data type to return?

  I have a custom control that has a SelectedValue property.  It is basically a ComboBox control, if that helps.  Anyway, I have a business object that I'm binding to this control.  In some cases, the business object property that I'm binding to the control is a System.GUID, in other cases, it is a System.Int32 or System.String.  My delimea is that if the custom control's internal _selectedValue member is Nothing, because the user never selected a value or the selection was cleared, I want to return a valid data type to my custom business object. So if I'm binding to a property on my business object that is a System.GUID an ...Show All

• Windows Forms Forms-only components

  Hello everyone, I was wondering if it is possible to do the following and it is, how to do it. I have a component but that particular component should be added only to a form. People should not be able to add it to an user control. I am afraid that I do not know of any automatic method however if were to create an EventHandler for the ParentChanged event of it you could do something like this: void MyComponent_ParentChanged( object sender, EventArgs e) { if ( this .Parent is UserControl ) { this .Parent.Controls.Remove( this ); MessageB ...Show All

• Visual C# C++/Win32 for the C# Programmer

  Hello, My name is Vincent and I did not know what a semaphore was (until recently). Recently I've noticed (and it's been pointed out to me) that my lack of C++ and the resulting lack of intimate knowledge of Win32 is not helping me as I continue to dive deeper into C# (and as the language matures).  Generics for instance have their roots in C++.  Concurrent programming in .Net is all about the OS.  I know and have studied the CLR abstraction of threading concepts (books, papers, code samples, etc) and have experience writing concurrent code but still I feel a little in the dark not knowing C++ and the intricacies of the OS. ...Show All

• Visual C++ CDialog::DoModal asserting in CWnd::DestroyWindow

  To Brian and Martin, who were involved in helping me out with this , please don't shout at me... This thread does follow on from that post - and I'm now investigating refactoring a static library which contains a few MFC classes into a shared DLL - using __declspec(dllexport) to export functions and classes that will be needed across all facets of the solution that need the shared functionality. I've looked all over the place for an answer to this question - and found loads of other people using MFC 6, 7 and 8 with similar problems. I'm not going to be naive enough to suggest that MFC has a bug - I'm well prepared for this being a s ...Show All

• SQL Server File Connector w/ Execute Package Task Expression Bug?

  Hi. We are trying to 'drive' the list of package to be executed by placing the package file names in an external datasource (a flat file). The idea being that the end user can modify the file to switch on / off the packages to execute or modify the order they are executed without having to use the Visual Studio IDE. We've gone about this by the following: 1)   Read the external datasource into a recordset using a dataflow task. 2)   Used a foreach loop to iterate the recordset, saving the value in a package scope variable so we can use it later on. 3)   Within the loop there is a Execute Package Task which ha ...Show All
