AFAIK it is the only way you can create a brush object at instantiation that can be accessible to OnPaint.

As I'm about to do in my project, I think it's better to make pens and brushes member variables -- or in my case, static variables because the same brush can be used across all instantiations -- so you don't have to constantly construct and dispose brushes in the OnPaint method.

You can, but make sure you call dispose on them at the end of the method, else it with quick swallow all your RAM.

Hi leppie,
I have a question about that that I simply can't find a simple answer to in the MSDN documentation.
If I create a pen, brush, etc., in the OnPaint event, do I need to manually displose of it before exiting the OnPaint event?
Thanks!
Marc

Preferably! The GC will dispose them eventually. Have a look in task manager to see if extra handles are continuously created.

Is there some handy package or library that someone can recommend for handling automatic or semi-automatic updates. Essentially, it would periodically check to see if there's an updated version of a package or library and then install it. Ideally it would be seamless to the user and would allow updating only the changed files and not require downloading an installer everytime.
Any suggestions? ZeroG.com has something called PowerUpdate which is similar, but I'd rather have something that is free and in my own control.
Thanks,
Arun

There is a component on GetDotNet that does just that.

I have written the user control similar to Outlook bar, written in C#. I want to browse items( Images and strings as in Outlook bar) in the same at design time and want those to persist run time. Right now I have provided collection editor class for this. Due to collection editor class I am able to add items at design time, I am able to see those items in my control which is placed on the client form, but the added items are not seen on the control when I run my application. Also "AddRange" statement for user control is not added in the "InitializeComponent" function of my client form. I have also tried a typeconverter for my user control but no effect. Please help.

Okay, before I start, this may be really simple to remedy, but I haven't spotted it yet, so here goes.
I'd like to use a control in my C# application that:
1 - looks like a normal list view control in large icon mode (so plain white, large icons with labels)
2 - Allows the user to position icons arbitrarily within the control (so no alignment, but a track kept of where each one is)
Basic idea is hopefully going to end up like moving flowchart elements in Visio, or in the old versions of Rational Rose. I'm going to eventually want to join them together with flow lines.
Now, as far as I remember, ListViews in Windows Explorer allow these abilities. I can place my folder icons all over the place sometimes, and they don't have to snap to grid or anything. Am I just missing the right settings in the control properties? I can get it to show the icons, but it won't let me drag them to a new position within the control (gives me a no-go pointer even though AllowDrop is set to true).
Any help is much appreciated.
Cheers

Ok, so I know I'm missing something very basic here but I am having a problem understanding how ConfigurationSettings work. I've looked at the various examples but still can't get it to work for me.
I have a Windows application ... application name testapp. I've created a configuration file named testapp.exe.config and copied the file into (in this case) the bin\debug directory along with the EXE file. The config file looks like the following... copied from one of the examples:
<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
<!-- The following code uses the predefined appSettings section. -->
<appSettings>
<add key="Application Name" value="test application name" />
</appSettings>
</configuration>
In my code I have the following statement.
string appName = ConfigurationSettings.AppSettings["Application Name"];
What I get is appName = null and the config file is removed form the debug\bin directory.
So, 1st, should the config file be being deleted..if so, are the actual settings stored someplace? and 2nd, what am I missing by not being able to read the value for "Application Name" give the above code and config file.
Thanks for the help

Hi,
This could help:
Add a file named "app.config" to the project and compile your solution. Visual Studio .NET will automagically search for a file with that name (app.config) inside your project and create an output file to bin/debug (in this case), then, if you need to change the contents of that config file, modify app.config and it will be reflected on the output file.
If you change the output file (when I say "output file" it means "testapp.exe.config") directly it will be overwritten by VS.NET on the next build.
Hope this helps.
(if I wasn't clear, please tell me and I will try to be  )

It should work. Works for me. Make sure the spelling is correct. The AppSettings are case sensitive.

Is it possible to have 2 different C# Class Library Projects which individually compile to their own dll and then add the 2 projects to a solution and make them both compile into 1 dll while still allowing for them to individually compile into seperate ones when accessing only the individual project?
FYI: I am using VS.NET 2002
Thanks

Yes: you create another empty project, and, when adding the files to your project, on the open file dialog, instead of clicking on the "Open" Button, click on the small down arrow on its right, select "Link file", and you're ready to go.
