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.

my system32 is full of that crap. How did you get access to my machine?

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)
|
|
|
|
|
Insert the following before the parse attempt.
string testString = fwfreg.LoginTime().ToString();
Then set a breakpoint.
You can also use TryParse, which catches the exception internally for you and returns true or false.

"This time yesterday, I still had 24 hours to meet the deadline I've just missed today."

What does fwfreg.LonginTime() return? What does the string look like there?

Hi,
I'd like to develop a simple Windows application in which I have a rich text box (on which I have a tight control) and a version management system handling the files I'm editing, so that I dont modify my original text file, and I can come back to a previous version.
Like I want to integrate the check in and check out in the editor, but I want to give the editor some features I dont find in standard editors (for my private needs).
Is C# the wrong language for this? Like I've invested a lot of time learning it,
it would libraries to handle this would be written in C++ but
I'd rather avoid the complexities of C++.

Hi,
I did my own IDE in C#. It includes a full featured text editor, which is not based on
a RichTextBox, instead I use my own data structures and paint everything to a Panel myself.
This allows me to implement all the things I want without being hindered by the peculiarities (shortcomings?) of an RTB. An RTB is not very good at handling large files for one. And
I have seen many posts struggling with syntax coloring; I do mine inside the Paint handler,
just coloring the part that is visible. This works just fine, supporting a whole set of
languages.
I did not interface to a version management system yet, but that can't be very difficult.
Conclusion: I did all this once in Java, later on a repeated and extended it in C#.
These are the only languages I would want to do it in right now!

Yes, I agree about the weakness of the RTB.
Actually I saw a built-in editor control that was very nice in TKInter that comes with Python, because it has marks and tags, which I think I need.
A mark represents a floating position somewhere in the contents of a text widget. A tag is like, well, a pair of marks under the one name, which defines a range of characters and those characters can be given a font, a color and other nice properties.
Now if I could get that in C# I'd be happy. Maybe I should build my application
in Python...
