Hi people,
I have a user control that draws a Bezier (drawing occurs in OnPaint and OnPaintBackground). This control is used in a windows form. Is there a way to get the graphics of that control to be able to save it in a file?
thanks,
Talal

hi again,
well I managed to send back the Bitmap to the main form, but I had to recreate it in the returning function. I was wondering if there is a way to get back what I had already drawn in the control.
thanks,
Talal

hi there
i'm trying to extract certain information from an HTML source, i've used the : WebClient from the .NET library to Screen Scrspe the web page the second part is to use RegEx to EXTRACT usefull information to me from the HTML source available and because i'm not very familiar with regular expressions i need help to do this for example:
I NEED TO EXTRACT THISand then to place whatever is extracted within XML tag (i.e. converting)
thanks and regards

<td class="subhead" colspan="2">(?<content>.*?)</td>
where group "content" will contain text "I NEED TO EXTRACT THIS"
or more generaly,
<td(.*?)>(?<content>.*?)</td>
RETester[^] is nice place for testing... Check out Reg Ex Lib, too.
best regards,

Hi for all
I have nine buttons in my form and I would like how I can include a button's reference in an arraylist. I'll modify the text's value of a some button by this reference. How can I do this?
Thans for all
Alex

Does simply adding the Button object not work? Something like
<br />
class MainForm<br />
{<br />
private Button b1 = new Button("B1");<br />
private Button b2 = new Button("B2");<br />
<br />
ArrayList a = new ArrayList();<br />
<br />
<br />
public void AddToList()<br />
{<br />
a.Add(b1);<br />
a.add(b2);<br />
}<br />
<br />
private void ModifyText()<br />
{<br />
foreach(Button b in a)<br />
{<br />
b.Text = "Long live Senthil";<br />
}<br />
}<br />
}<br />
Regards

hi
i want to know what is the Diffrence between the DATASET and the DATAREADER
and when you use each of them
thankx
|
|
|

datareader is a connected resultset, while the dataset is disconnected.
Have a look on MSDN for more detailed info though.
Cheers,
Simon

Uhhh.... YOU have to write the code, we're not doing it for you. You solve your own problems, we just help.

Hello,
I'm absolutely new to programming, so please don't be too hard on me...
I'm trying to make a simple form application to hide or show hidden files. When I try to run the application I get a "System.NullReferenceException: Object reference not set to an instance of an object."
I found many topics related to this problem, but I still cannot figure it out.
Here's the code:
partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void HideFiles()
{
RegistryKey MyKey = Registry.CurrentUser;
MyKey = MyKey.OpenSubKey(".Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced", true);
MyKey.SetValue("Hidden",2);
MyKey.Close();
}
private void ShowFiles()
{
RegistryKey MyKey;
MyKey = Registry.CurrentUser;
MyKey = MyKey.OpenSubKey(".Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced", true);
MyKey.SetValue("Hidden",1);
MyKey.Close();
}
private void ShowButton_Click(object sender, EventArgs e)
{
ShowFiles();
}
private void HideButton_Click(object sender, EventArgs e)
{
HideFiles();
}
}

NullReferenceException is a very basic exception you get when you declare an object reference but do not assign a value to it (or, in your case, have a method returning null and assigning this null to your reference) and then try to access the non-existing object.
Just debug the code then you'll see where the exception occurrs.
I assume the subkey you're trying to open doesn't exist (it should start with "Software", not ".Software").

Thank you, thank you!!!
The 'dot' did it! Pfff, if I knew that it was that simple...
I presume that once you get a little more experienced, you don't make any more mistakes like that. (I hope...)
Thanks again...

Though I am not much more experienced than you ,I may say, once you started to face with errors , you learn how to deal with them , esp. using debugger (watch is a great tool btw..), understand and comment on errors, than find the appropriate solution..

I am writing an application that allows user login by windows authentication (includes domain and username).
For example:
Username: MYDOMAIN\MyUser
Domain:MYDOMAIN
If this username is valid, application will check for user's role, if user's role is BUILTIN\Users then this user can do their works.

It's nice that you are writing an application, but what's your question?
