I am opening an image on a picturebox using:
pictureBox1.Image = new Bitmap(openFileDialog1.FileName);
then i am drawing some lines and curves on the picturebox using the event:
private void pictureBox1_Paint(object sender, PaintEventArgs e)
such that the painted lines and curves are drawn over the image opened on the picturebox. Now, I want to save the image containing the original image and the lines or curves drawn on the picturebox as one image. Please tell how do i do that........
Thank You

Well, the first problem you have is that you're not drawing the lines on the image. You're drawing on the surface of the picturebox control. So, everything you see appears as though you're drawing on the image when you're not.
You have to draw the lines on the bitmap you created, then you can save the changes back to the original files.
Speaking of that, you have a second problem. When you created a Bitmap object using the overload that you did, the file gets locked for the life of that Bitmap object. This means you can't save any changes back to the original file.
To get around this, you have to create a FileStream object, opening that image file, then create the Bitmap from that Stream, then closing the file. This will prevent the file from being locked so you can save the changes back to it.

Create a composite control where there is a button (or have a hotkey like a function button) to launch the common dialog control or ColorDialog - that handles opening the dialog.
Trap for when the ok button specifically is pressed and then update the backcolor on your control with the color selected by the user.

<br />
<br />

<br />
Dim rk As RegistryKey = Registry.My.Computer.Registry.LocalMachine<br />

<br />
rk.OpenSubKey(reg_key_a, True).SetAccessControl(rs)<br />
<br />
End Sub<br />

Is your app running under an administrator account?

Unless the account that's running your code is in the Administrators group, this won't work. Users don't have write permissions to anything under HKEY_LOCAL_MACHINE.

I am working on an SDK. The SDK supports plug-ins. The issue I am running into is when I test a new build of the SDK, none of the Plug-ins will load. The reason they will not load is that they were developed with v2.1.5689.0 of the SDK. Since I do nightly builds of the SDK, it is now v2.1.5690.0 and the plug-in will not bind to it. I understand that they might not work if there were some interface change or such, but there typically is not. Is there a setting I can use in the plug-in project to cause it to bind to the major and minor number only in the version (OK, maybe the path as well, but definitely not the build).
Tanks for your support

On a WinForm I'm working on I want to draw attention to two particular controls.
One is a TextBox and I can set the BackColor property.
The other is a DateTimePicker, and...
"
Setting the BackColor has no effect on the appearance of the DateTimePicker. To set the background color for the drop-down calendar of the DateTimePicker, see the CalendarMonthBackground property.
"
I don't want to set the background color for the drop-down calendar, in fact I'm setting ShowUpDown to true so the drop-down calendar won't be available anyway.
This particular application is just a test bed for a class I'm debugging, so it isn't worth deriving a custom DateTimePicker or using a third-party control. That's why this is a rant. However, if anyone has a simple solution I'd like to hear it in case this comes up again in the future... as it likely will.

Why not put the DateTime picker in a Panel that's slightly larger and set the color of the panel? That would give you a bit of a border and you could even 'flash' it if you wanted to.

Yeah, I might do that, thanks.

Hi,
I'm looking for an ECMAScript-327 (ie ECMAScript Compact Profile) interpreter for the .Net Compact Framework, to run on a WinCE platform. Do you have any idea where I could find this ? I saw (but didn't further investigate) ecmascript-net[^] - do you think this may be useful for me? Any other trick I may try ?
Thanks
Sebastien

Well from what it says on the page "EcmaScript.NET is an open-source implementation of EcmaScript based on Rhino (JavaScript for Java) written entirely in C#." it sounds like it's exactly what you want.
Only you know your requirements though, so you should download it and give it a try.
Come up with a list of what you absolutely must have it do, and then test everything on your list.

Today I tried to remove all memory leaks from my application.
I used the tool .net memory profiler.
Some of my objects that use a datagridview are not collected by the garbage collection.
I searched google and there are a lot of hits with that problem,
not all for datagridview but this one seems to be the same problem:
f.e. :
http://www.scitech.se/blog/index.php/2007/10/05/memory-leak-in-toolstriptextboxcontrol/[^]
There's a static event "UserPreferenceChangedEventHandler" which is not unregistered in the right way.(it's the same event with my objects)
The article describes a workaround which uses reflection to unregister manually from the events.
I did a much easier workaround:
Just called dispose on the eventslist of the datagridview if my objects are deleted.
f.e.
mObject.dataGridView1.Events.Dispose()
This seems to work well!?
The objects are collected by the garbage collection after I do so!
Do you think this is ok?
Or do you have another solution for that problem!
I found nothing on msdn.
Thanks for any help!

Hi Guys,
I'm looking for a way to store resources in a secure centralized file. The idea is to imitate how Zip files work in windows where you can get a path like:
C:\Temp\MyTemp.zip\MyWebpage.html
I can't map a path directly into a zip, but this is what I'd like to achieve.
Does anyone have any ideas how to achieve this result?
Regards
Tris
