  hi! I want to show a folder content in a ListView. And I want to show near each file an icon associated with its type. is there a way to do this You'll know it's a folder. So just add your own image to the ImageList. yes, it is it. thank you. but how can I get an icon for a folder Icon.ExtractAssociatedIcon() can do this. Check this thread for code.

• programmer01 Controls move differently when scroll bars appear

  I have some controls I am creating at runtime within a panel....when i click my buttons the controls is created in this format equally spaced between them control1 control2 control3 when the scroll bars become visible and I scroll down the the most recent control that was created.....and try to create another one....the controls is spaced waaaaaaayyy further than its set to do.........

• mhawb removing ApplicationExit event handlers

  In the help : Application.ApplicationExit Event Because this is a static event, you must detach any event handlers attached to this event in the ApplicationExit event handler itself. If you do not detach these handlers, they will remain attached to the event and continue to consume memory. so i have Application.ApplicationExit += new EventHandler( Application_ApplicationExit ); and in Application_ApplicationExit Application.ApplicationExit -= Application_ApplicationExit ; is that right I'm using it to release some unmannaged resources. And I was wondering about -= because i don't have the variable so using -= new EventHandler(Application_ApplicationExit") is kind of weird. And in the doc it is ...Show All

• vaioks Best Component for the job?

  Hi, I'm not sure if the header is the right one, so if it's confusing, I'm sorry. I come from Sun's Java world and don't know my way around the GUI programming in C# yet. When I want to display a tabular data structure in Java, I use the JTable object, which is suitable for any type of tabular data, and can be provided with a 2 dimensional array of objects that can be placed in the table using the toString() method, regardless of the data source that is used for that table. I'm trying to do something similar in c#, and I'm having trouble working with the DataGridView, which is simple only if you connect it to a datasource. I have a TCP server program written in c# that needs to display data about connected clients. I need to ...Show All

• lnkaye Settings.Default.Save( ) won't save!!!

  Hey guys, I'm using the built in Application Settings datastore in VS 2005. I am running into two problems though. The first one is that it does not save when I call Settings.Default.Save( ). I have tried putting in this on the form close event and even tried it on a button click all to no avail.. Any ideas Problem #2: For some reason by default the property it creates is readonly ! I have to actually go into the studio generated code and add a set method in the property. Thanks guys for any help, Chris Hello! I did as you suggested and it still won't save. Does it have to be in a FormClosing( ) event or can it be called on a button click (which is what I am doing). Thanks, Chris Here's my code: pub ...Show All
