Two things:
1. You are REQUIRING your match to occur for the entire string since you are using '^' and '$' at the beginning and end, respectively, and
2. You may need to escape the '>' and '<' characters.
Implementing both of the above, your regex becomes...
Regex rx = new Regex(@"(\>=?|\<=?|=)\s*\d+\s*"); Let me know if this works as desired,

Hi guys,
I have a problem regarding threads in my application. I got a Form in my app which owns a class derived from WarnModule (see http://pastebin.com/m72a3f841[^]) that periodically triggers some kind of warning (i got different implementations of that). The problem is that the finalizer of the WarnModule does not get called when the application that owns the WarnModule-derived class wants to exit and the still running thread in WarnModule then blocks the application from exiting.
How can i solve this issue?
Thanks in advance,
Lucas

You will need to some how signal the thread that it is time to exit. One way to do this (logically, but I leave coding it up to you) is as follows...
1. Create a shared boolean object initialized to false called "TimeToExit"
2. Periodically check the value of TimeToExit from the running thread. If true, exit.
3. From the main thread, after setting TimeToExit to "True" and waiting for some amount
of time without the thread ending (the maximum thread response time), kill the thread :( Note that you will NOT need to make the boolean thread safe, as one thread is reading and the other is writing, and no inconsistent state can occur here. Hope this helps,

That's what i am already doing, but I dont know where to set that flag from. The ApplicationExit event does not get fired until the object has been disposed, which never happens because the Thread keeps running.

What event triggers you wanting to exit the application? Form.Closing? Somewhere in your code there will be SOME event (that I can't guess) which is triggering this desire to exit. If it is user initiated, then there must be some event like Form.KeyPress, Button.Click, Form.Closing, etc. If it is initiated by code somewhere, then just add that line to set the bool at that point. If you still cannot figure out where to put the code for this, explain what event is triggering the application exit and I can try to help some more.

I can signal the Thread to exit after Application.Run() returned, so that solves my problem.
But what I really wanted to do was to make the object clean up it's own mess (as you are supposed to do it in OOP), but I didn't succeed in that.
I tried stopping the Thread in the Finalizer and in Dispose() (i derived the class from IDisposable), neither worked.

Hi all,
I am using the Find method if the RichTextBox to search for a certain word within the control. But how can I move to the line where the text was found ??
int indexToText = richTextBox1.Find(text, RichTextBoxFinds.MatchCase);
if(indexToText >= 0)
{
}
Many Thanks

Can't you just do the following?
int indexToText = rtb.Find(text, RichTextBoxFinds.MatchCase);
if(indexToText >= 0) {
rtb.Select(indexToText, 0);
rtb.ScrollToCaret();
} Hope this helps,

Hi,
Thanks for the response, but when I try and search for the next word that matches the find it keeps repeating the same line within the RichTextBox. What am I doing wrong?
This is the code I'm trying...
if (this.activeRichEdit.Find(textBox1.Text, 0, activeRichEdit.Text.Length, options) != -1)
{
int endIndex = this.activeRichEdit.Text.Length;
int findIndex = this.activeRichEdit.Find(textBox1.Text, 0, endIndex, options);
this.activeRichEdit.SelectionColor = System.Drawing.Color.DarkRed;
activeRichEdit.Select(findIndex, 0);
activeRichEdit.ScrollToCaret();
}

int foundIdx = 0;
while ((foundIdx = rtb.Find(textBox1.Text, foundIdx, rtb.TextLength, options)) >= 0) {
rtb.Select(foundIdx, textBox1.TextLength);
rtb.SelectionColor = System.Drawing.Color.DarkRed;
foundIdx += textBox1.TextLength;
}

Hi
i think the richtextbox should do this automatically for you. if you call Find , it'll select the text that was found, and should ensure that the selection is visible.
if it does not ensure that it's visible you can do this by calling ScrollToCaret()

Hi All,
I want to make a component,circular in shape, which inherits the property of button eg change the label, resize etc,also on which I will apply Bitmap using C# for my working project.
Pls help me.
Somit

Override the OnPaint method, draw a circle using the bitmap to fill. Override the OnMouseEnter, OnMouseLeave, and OnMouseDown events to set the style you want and to refresh the button's client area.

How I can document my C# project?
What must be considered and what should be avoided?
I want to know the best approach. If some one has a sample document then please send me on sami@xpert-tech.com or samibaba.khan@gmail.com
Thank you in advance.

I like to use N-Doc for internal documentation (turns your three-backslash xml comments into html documentation). It is a free download, so just search online for it.

NDoc only really works on .NET 1 and .NET 1.1. If you're using higher versions of the framework, you should look at using Sandcastle.

How can i do this without creating new form object?? in my application i have a win.. form and

One of the better methods for doing this is to implement the Model View Controller (MVC) pattern. Have a read of this pattern and then see how it helps to solve this issue. (Alternatively, you could use an Observer pattern, but the MVC is probably going to be a bit easier for you to get your head round).

could you please tell me links where i can read about model view controls..

You could always read this[^] article from our very own Marc Clifton.

I agree with the other answer however I initially interpreted the question slightly different. (I probably read it wrong) So just to check as this is the way i initially read your query.
Were you saying:
1. you create an instance of FormB from FormA
2. FormB creates a list item that you want to add to form A.
3. However when FormB closes you no longer have a reference to formB so cannot add this item to formA's list view?
|
|
|
|
|
In the B form you need a reference to the instance of the A form. Send a reference to the A form in the constructor for the B form, and in the constructor put the reference in a variable declared in the B form.
Experience is the sum of all the mistakes you have done.

I think all these anwers depend on the actual question as Im not 100% clear on the situation. (apologies if its just me)
If formB just returns to formA eventually anyway, just expose a property on FormB to return the listViewItem like so... (+ with better naming conventions)
using (FormB b = new FormB())
{
if (b.DialogResult == DialogResult.OK)
{
AddItemToListView(b.ListViewItem);
}
}
Obviously the above assumes formB's role is to create a an object which will be displayed in formA's list view. As i said before i think the question was open to different interpretations as seen with the answers.
