Hi Stancrm,
Thanks for the link. I should have mentioned in my original post that I already had Word-Wrap set to false and Multiline set to true, I completely forgot to mention it. As for my insult, I'm sorry I lashed out at you like I did, it wasn't very nice. I'm sorry.

You didn't search too hard then - its on MSDN: http://msdn.microsoft.com/en-us/library/system.windows.forms.textbox.scrollbars.aspx[^]
It says that Horizontal scroll bars are only avaiable when Wordwrap is set to false. So, either you have wordwrap on, or you have multiline off - in which case there is no space for a scroll bar so you don't get one either.

I have multiline set to true and wordwrap set to false. The horizontal scrollbar has always worked. But for some reason it doesn't work anymore. It never shows up.

I just tried it (VS 2008 SP1) and I got it/them. As long as you also allowed space for the scroll bar.

In my application I have a MainMenu docked to the top, a ToolStrip docked beneith the MainMenu, a StatusStrip docked to the bottom and a TextBox control docked to fill the remaining part of the Form (in the middle). So maybe it's not working simply because there is a StatusStrip directly under it. Hmm... But then again, it has worked in the past. Which is why I'm confused.
I tried the code found in the pages I visited from the links above (replies) but even though the code is different, I have the same problem.
Thanks for your help, I appreciate it.

Hi All,
I am developing one IE add on which detects HTML document events like click, change etc.
Now, I want to add the functionality like capturing menu bar clicks, toolbar clicks or address bar click.
I am searching in MSHTML & SHDOCVW dll, but not got anything relevant to this.
If anyone has the idea, how can I achieve this, please let me know.
Thanks In Advance

I have a situation like follows :
void EventHandler(Function arguments)
{
//Set of global variables takes in values from the Function arguments
Example :
Sum = Function Argument1;
Value = Function Argument2;
//Makes a call to Function (say, 'FunctionProcess') with the respective values.
Example :
FunctionProcess(Sum,Value);
}
My query is that what happens if I receive an event and am in the middle of processing the so called "FunctionProcess" and i receive another event. The new event has different values of 'Sum' and 'Value'. What would be the result? Would it crash the normal functioning of the program?

That can't happen in a 'normal' situation as each method call including your event handler is sychronous (blocking).
If there is any threading going on, that can happen however, and you would need to lock the values.

Adding to Dave's reply, a lot of handlers execute on the main thread (aka GUI thread). Obviously that thread can only do one thing at a time, so it deals with the messages from its input queue one by one. That is why changing a Label.Text and performing a lengthy operation in one handler only shows the changed text after the operation has finished.
However there is a whole bunch of asynchronous handlers (mostly "input handlers" such as for networking, SerialPort, etc) that run on different threads, normally ThreadPool threads. I did a little experiment[^] on the subject. One of the conclusions is methods called from such handlers could be running concurrently, depending on the source of the event. Say two serial ports calling the same method. So if you are not sure, do at least one of the following:
- check the documentation (it often isn't very specific on this issue);
- perform a little experiment (as I did);
- when still in doubt, or to make sure, provide a synchronization mechanism (maybe use a lock); be careful though since that may cause new issues.

my problem is that I don't know how to merge images from different pictureboxes and make them as one image..
can you give me some pointers or codes on how to do this? I'm still a newbie on programming so i really need help.. and i need to finish my software in less than 1 month.. thanks in advance..

Hi,
If i have this class for example :
<br />
public Class A<br />
{<br />
public void Func1()<br />
{<br />
....<br />
}<br />
<br />
virtual public void Func2()<br />
{<br />
....<br />
}<br />
}<br />
<br />
Public Class B :A<br />
{<br />
<br />
override public void Func2()<br />
{<br />
...<br />
}<br />
<br />
}<br />
I don't want to override Func1 but i allso don't want it to be exposed to the user.
What is the best way to do so?
|
|
|
|
|
use "protected" instead of "public"
|
|
|
|
|
But if i will use "protected" i will not be able to access func1 in an instance of class A, Just in Class B!
|
|
|
|
|
From your question : "I don't want to override Func1 but i also don't want it to be exposed to the user."
That means -> Func1 must be
protected (Func1 visible to child classes)
or
private (Func1 is not visible)
From your 2. question : "But if i will use "protected" i will not be able to access func1 in an instance of class A, Just in Class B!"
That means -> Func1 must be public.
So, you can choose between them..
I think, you have a design problem.

What you want isn't possible with standard inheritance as far as I can work out if I'm understanding you correctly.
If you want a common function between two classes, but with their own implementation, and an additional function in one (or more) of them, I would use an interface.
public interface IInterface
{
void Func2();
}
public class A : IInterface
{
public void Func2()
{
}
}
public class B : IInterface
{
public void Func2()
{
}
}

I think he wants class B to make its inherited Func1 non-accessable.
|
|
|

The best I can come up with is the code below. So long as the classes are in a seperate assembly to the code accessing them, then it will work, although it only hides it from intellisense and creates a compile error if there is an attempt to use the method. If they are in the same assembly as the accessing code then the method will be visible, though unuseable.
I'm not keen on it as it's not very OOP - if B derives from A then it should have everything that A has, but MS do it all the time, so who am I to question this method?
public class A
{
public void Func1()
{
}
public virtual void Func2()
{
}
}
public class B : A
{
[EditorBrowsable(EditorBrowsableState.Never),
Obsolete("This method is not useable in this class", true)]
public new void Func1()
{
throw new InvalidOperationException("This method is not useable in this class");
}
public override void Func2()
{
}
}

You want to override the method and make it non-public? That's not allowed. You could mark it Obsolete or have it throw an Exception.
P.S. Most likely you want class B to wrap class A, not derive from it. And maybe use an interface.
