Through a .dll.

I thought that only worked with a win32 dll.
|

|

Look at Assembly.Load method.

This is my question, lets say that i have a picture, his resolution is 1600*1200,, and i want to know the RGB number of the pixel 100*100 (for example), and by the RGB number i mean the Red, Green and Blue number that are combined to make a custom color.
Note:
If it is posible, i can use other method, the important thing is that i need to be able to compare one pixel color whit other pixels colors.
This is because i am currently making a robot that is able to follow lines, for this i am currently using a PIC(Programable chip), but since this just works whit a crappy line of white tape on the floor and this robot is already using a labtop to work, it will make muck more sence to use a cam, and stop using that crappy tape, and it will make much more sence to use signboards to extend is functionality.
Any help will be very apreciated

Hi,
the Bitmap class is intended for holding images. It has a GetPixel(x,y) method that
returns the Color of a single pixel. The Color struct has properties Red, Green, Blue.

tanks works great, i have already google this but i tink i remember why i dont use it, it was because when i crate a bitmap:
Bitmap bmp = new Bitmap(@"C:\1.jpg");
the "Bitmap" was pointed like a namespace not a type, however i remenber someting similar so i put it like:
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(@"C:\1.jpg");
I have spend some time looking for the source of this, but seems to be an internal error.
tanks fot the help work great.

You're welcome.
BTW: you can omit the "System.Drawing." stuff if you put a using System.Drawing;
near the top of your source file.

How would i change the contents in a read only text box from another form button.
My parent window has a read only text box on the top, a button that opens another form asking which item *4 buttons*
I would like the information in the read only text box to be changed when the user clicks on the certain button, how would i do this?

If you are using the VB.net please make a global variable in module
and on the button click's event set the value in that global variable.
And on the other form's load event please write
textbox1.text=basic.Myvar.ToString();

Create a class library project and put your code into it.

Hi,
You may try ComponentOne's Studio Enterprise for .Net 2007. It is a complete visual development package which contains two grid controls as well (C1FlexGrid and C1TrueDBGrid). These two grid controls has rich set of properties and method to help developers in developing exclusive .Net applications.
You may download the evaluation version from http://www.componentone.com/Downloadcenter.aspx[^]
for better understand you may see the samples at http://helpcentral.componentone.com/samples.aspx[^]
If you find it suitable for you then you can get the license easily.
I hope this helps.

Hello,
thanks in advance for your attention.
I'm delving into application registration for the first time. I've figured out my approach in regards to handling registration, in no small part based on Heath Stewart's great article (http://www.codeproject.com/csharp/ComputerID.asp).
Yet I'm faced with a problem: I wish to allow the user a 90 day trial period of the application. Beyond those 90 days, only a registration option will be available. Now, I need to store a "application installation date" value somewhere locally, as I don't wish to rely on an available Internet connection. But where do I store this, so that the user cannot effortlessly simply uninstall and reinstall the application for a further 90 days trial? I reckon the registry is the place to hide this, but does anyone have a safe tip on exactly where to put it, so it won't interfere with other applications on the machine?
Like I said, thank you in advance.
Morten,
Denmark

The sad fact is, the only way you can achieve this is to be anti social. You need to hide the data so that the user can't find it.
I never use the registry, I would put a file in the system32 folder, and name it something starting with MS so it looks official, something like MSVWML.DLL. Then store your date in there, but not as plain text, you don't want anyone to be able to modify it in notepad.

That works fine. Most people fall for it.

how should I debug this error which says "Input string was not in a correct format"
Here is the code:
private void frmLogin_Load(object sender, EventArgs e)
{
this.Visible = false;
if (FWFAddin.userid == "")
{
FWFAddin.FWFAppSettings fwfreg = new FWFAddin.FWFAppSettings();
long dtNow = DateTime.Now.Ticks;
long dtThen = long.Parse(fwfreg.LoginTime()); //I get an error here
long dtFinal = dtNow - dtThen;
if (dtFinal > 36000000000)
