First off I have found that designing with a 17" monitor to help this, however you may wish to set your resolution to 1024 x 768 which I believe is considered standard resolution. You can also resize your controls when the user maximizes their screen to keep everything standard. Most standard controls also implement the dock property which will essentially bind the control onto your form so that when the form is re-sized they stay the same distance apart from each other.

Help! Need advice on best .NET resources!

Greetings all!

I am new to programming .NET and, to be perfectly honest, I'm not really an experienced programmer. I'm an engineer that is going to have to be doing some development. So, I'm looking for the best resources available for learning/developing in .NET. Where do you go for on-line information, add-ons... those things that make development time easier? I've been hearing about "communities". Do you really use those and are they valuable, or do you spend more time in discussion forums like this? What are the best forums?

Any information would be valuable. I appreciate your time!

Jerry

is the whole delegate BeginInvoke/EndInvoke the best way to do asyncronous events? I'm not familiar with them.

I noticed that in the Windows Forms editor, if yuou insert a textbox, but dont set the multiline property to true, then you cannot increase the height of the control, i just wondered how this is done. Smile | :)

I need to make my control such that it does not loose focus when the user clicks the tab button, how would i go about doing this. I have tried capturing it in the OnKey.. event, but the control still looses focus.

I don;t think that this is something that could be done at the control level. Using tab to move from control to control is IMHO more of a form level process. I would hate to think that a control would be allowed to grab focus and not let it go like that.

If you want to achive it at the form level just set the tabstop property of all the other controls to false and focus will have no where to go.

If you are trying to do this in a custom control you are writing then I don't think that you can.

it must be possible, im sure the TextBox/RichTextBox classes that come with the frameowkr can do it.

Did you try KeyDown instead of KeyPress? Are you canceling the event in your handler with SystemEventArgs.Cancel?

It depends if they are child forms or owned forms (the latter are not confined to being inside the owner form).

I don't know if ther is an OwnedForms collection, is there?

The KeyPressed Event should do this, regarding other question about caps lock, i had a quick look and couldnt find anything.

im working with the control class btw.

but i am using the OnKeyDown/Up to capture the events, i just wondered if i had to make a mtheod myself to work out if it is a letter, or if the framework already provided that ability.
