• smithsf22 Image not shown in Treeview Control Node

  Hi, I have a windows application developed in C#.NET , Framework 2.0, and it's output type is Windows Application .

• Hamed JI Adding Components to Windows Forms

  anyone have any links on how i would add a component control to my windows form I created a component and now i want it to be inside my panel on my windows form but I cant find much info on the net to help me out though.... to add a control, you need to add it to the control container. Example if I create a control at runtime and want it on the form, I add it to the Controls collection: this.Controls.Add( myControl ); then I need to set the location of where I want to show that control on the form using the control's location property. So in your panel, try this: this.thePanel.Controls.Add( myControl ); does this work to make it "show up" - you need to set the location property to give it the pl ...Show All

  I need to programatically find the particular port that is associated with my device (which is connected though a USB adapter).

• SonicWave consuming .net 2.0 dll from .net 1.1 using VS2003

  Is it possible to consume .net 2.0 dll from .net 1.1 using VS2003 .net 2.0 dll might or might not be using 2.0 specific features, please let me know if its possible in either case. Thanks, Hello. Unfortunately you cannot reference a .net 2.0 assembly from your 1.1 application. The essense of the problem is that you can't run two versions of the framework in the same process. I would recommend upgrading the 1.1 application to 2.0. Another suggestion is covered here which involves reflection but is in my opinion much more of a headache than just updating the 1.1 project to 2.0. if the dlls are compiled in native C++ compiler using VS2005, even then they cant be referenced in apps built in ...Show All
