Dear all, i am designing a testing tool, which will test the teststeps that is being implemented as functions in a dll.
User has options to pause/resume/abort the test execution. for pause i know i have to stop the execution after executing current teststep(function). i don't know how to implement abort functionality. if we kill the thread that is handling the execution then the state would be unstable.(coz it might read/write to some files). Is there any way to abort the test execution without having instability?
If you come across these kinda of situations plz share ur thoughts
Thanks

I can give you some thoughts based on my experience. A thread can be terminated in three ways:
1) The thread functio returns. (Recommended)
2) The thread kills itself. (Avoid)
3) Somebody else kills this thread. (Avoid)
You should always design your thread functions so that they returns when you want the thread to terminate. This way, you can clean up things, e.g., closing read/write files. In practice, use some thread synchronization objects, such as event, mutex or semaphore. When the calling thread wants your testing thread to terminate/abort, send a signal through one of these sychronization objects. This design is pretty mature and should resolve your stability issue.
Hope this answers your questions.
- It's easier to make than to correct a mistake.

Hello,
How do I specify what DialogResult value my dialog box is supposed to return to the caller? This assumes the caller called ShowDialog() to show my dialog box.
Thank you
|
|
|
|
|
what about:
this.DialogResult = DialogResult.Cancel ?
hard, hey?! 
|
|
|
|
|
Thanks, Mr. Lloyd! It's hard when you don't know it!
|
|
|
|
|
Glad you thank me! That's good behavior!
Certainly the experience help and being a beginner is always difficult.
That makes me think to an additional advice:
Download the documentation!
Then ... mhh ...
Open the index tab, in the "Look for:" text box type: "DialogResult"
You will see!
The documentation is a great source of knowledge!
Ans so is http://www.google.com/[^]

Hi
This is my first experiment with c#. I am making an application that must have two threads. One should handle the main dialog and it's message loop. I am starting the other thread in main method and this thread creates another independent dialog(which is an animated tasbar notification). But I should also be able to handle events(button clicks for example) in this second dialog. But my second thread is taking control immediately after showing the dialog and I cannot find a way to transfer control to the message loop of the second dialog. The following code snippet makes clear of what I am talking of.
<br />
public static void NotificationThreadProc()<br />
{<br />
Console.WriteLine("Inside notification thread");<br />
Notification n = new Notification();<br />
n.showNotification("Hello");<br />
<br />
Thread.Sleep(2000);<br />
n.hideNotification();<br />
n.Close();<br />
return;<br />
}<br />
NotificationThreadProc is the procedure name I passed as a parameter to ThreadStart(). Notification is my second dialog. Show notification simply runs a for loop resulting in animating the dialog to look like a taskbar notification. I need a button inside this notification and I need an event handler to be invoked when I press this button. But since the thread that created this control is busy sleeping. How can I make this Notification thread listen to events from inside the Notification dialog? Please help..Any small clue is highly appreciated.
Thanks in Advance,
venkat.

Hi
Im a beginner and need some help
How do i write to a text file that already has data in it. I basically want to insert the values i put in my textboxes as a new record in my txtfile. It must not create a new file or delete the existing records.
Also, i know i should put all the textbox values into an array, but how do i write this array seperated by commas to my txtfile?
ie. textfile looks like this:
John,15,motorbike,20,12
Luke,12,car,24,11
Please could someone help me out

Use the System.IO.File.AppendText method to open the file for appending.
You can use the string.Join method to join the values in an array into a single string.

Hello,

Threre are two ways.
1. you could pass the mainform reference to secondary form in the secorndaryform's contructor and use reference to change backcolor property.
mainFrm.BackColor=value;
or
2. Create an event in the secondary form which the mainform should register. when ever you want to change mainform backcolor just trigger the event from secondary form. The mainform's event handler should do this.BackColor=value;
Hope this helps.
Thanks and Regards,
Srini

Can you please tell me how can I 'pass the mainform reference to secondary form in the secorndaryform's contructor'?
I mean what's the exact code I should to the secondary form contructor?
Thank you very much.
|
|
|
|
|
public class SecondaryForm <br />
{<br />
public MainForm mainFrmObj=null; <br />
public void SecondaryForm(MainForm mainFrm)
{<br />
mainFrmObj=mainFrm;<br />
mainFrm.BackColor=colorvalue;<br />
<br />
}

does the object locked get unlocked? Is there some "guidance" on that in MSDN or somewhere?

I'm almost certain this is true, which is why using lock() is preferred over manually locking an object (and unlocking it in a finally clause).

What is the format of the data you are trying to parse?
---
b { font-weight: normal; }
|
|
|
|
|
Hi,
The format is yyyyMMdd
|
|
|
|
|
Are you sure that it's the parsing part of the code that is not working?
The expression in the Select call doen't really look like it should work. The value you are comparing the date field with is either a string or a date, but there are no apostrophes or # characters around the value.
---
b { font-weight: normal; }
|
|
|
|
|
Exaclty the way that you have done it. I tested it and it works perfectly.
Read my previus post again.

hello everybody in this forum.
first of all , i would like to thank every programmer that helped me in the last few problems i faced , Really i respect all of you in this great website for programmer to programmer experience sharing.
i face one problem in connection . every body knows that i can't connect to a user connected through DSL or broadband connection users cause their Private network is mapped by a NAT Router that Connects them to the outside world. That is fine
but i would like to connect to any user on the world wide web for these reasons i successfully programmed the following
-------------------
1)i succeeded to add my application to Windows Firewall programmatically to the exception list.
2)i added my application port that the messenger will listen on and receieve incoming packets from the outside world in SERVICES programmatically .
Services options are found in your current connection Settings under
Go to your control panel - > Network connections - >current connection -- > properties ->advanced -> Settings -> Advanced Tab -> Select your current connection -> and press settings - >this is where i added my application successfully once it runs programmatically through Hnetcfg.dll in system32 but the problem still exists
The problem is that my friends on DSL or broadband connection that have my application running , i can't connect to them directly even when i had their router ip address and my application also had successfully added itself in the above settings.
----------------------------------------------
I read in MSDN that there is NAT TRaversal . and they expose alot of interfaces like INATupnp , IStaticPortMappings and others interfaces which are existed in hnetcfg.dll but when i add that file to my application i don't find those interfaces.
Note:
------
i was on winxp sp1 and then installed winxp sp2 and also i didn't find those interfaces .
So any one can help me to make the router for Lan Users know how to deliver packets to their specified computers in Lan from the outside world ?
Please i want to reduce the traffic and bandwidth from the server itself by direct connection.
Human knowledge belongs to the world.
