Simplest way will be to programmatically populate the username and password boxes then click the login button.

What do you mean?
If I browse to the application my computer AD-account is automaticly used. No login page is used.
Starting browser like "run-as" doesn't help. (that works if win.auth. is used in IIS).
What credidentials is forms auth using? Doesn't seem to be browsers cred.

After carefull reading and understanding this link "http://www.codeproject.com/Articles/42258/Particle-swarm-optimization-for-function-optimizat".
I was trying to use the code , but because i am using Visual Studio 2012 and the code is from 2009 maybe the errors that i found were because of the evolution of the C# languange.
Can someone with C# experience help me update the code for the new Version ?

Sample 1:
foreach(int i in integerList)
{
try
{
// Do something which might throw exception
}
catch(InvalidOperationException)
{
continue;
}
}
Sample 2:
foreach(int i in integerList)
{
try
{
// Do something which might throw exception
}
catch(InvalidOperationException)
{
// Left blank
}
}
Question: In sample 1 we have "continue;" in catch block and in Sample 2 we have NOT written anything. Are they doing the same thing? If yes, which one is better practice?

They are both various shades of bad practice. You're just catching ANY exception here, without actually bothering to do anything about it. In both cases, the behaviour is the same - the loop keeps on iterating, but the reality is that you have just consumed something that has gone wrong. That is bad practice, so I would urge you to do neither case. Exceptions are thrown for a reason. Only catch them if you intend to do something with them, such as logging or you have logic in there to mitigate the effect, e.g. you might have some retry functionality that you need to use. Ignoring exceptions is the wrong thing to do.

Thanks for your reply.
I am catching InvalidOperationException instead of general exception (will update the question). However, we have plans to get logging in catch block instead of continue or blank.
The only reason I wanted to ask this, because I wanted to know if writing continue is bad instead of leaving it blank.
--> Our aim was to not do anything for the iteration where an exception is thrown.

Leaving it blank is bad: it "swallows" the exception, so that nobody ever knows it has happened. So the underlying problem never gets fixed until it has reached massive proportions.
If you are going to add logging later, then re-throw the exception (so you know it occurred in development) and add a TODO to the code to remind you to fix it:
catch(InvalidOperationException ex)
{
throw;
}Adding the TODO means it comes up in the Visual Studio Task List[^] automatically.

Small addition: If you catch Exceptions to log them or to do anything else that doesn't include mitigating the error, re-throw the exeption at the end of the catch-Block, either with "throw;" to re-throw the exact same Exception or by throwing a custom Exception and providing the original Exception as an InnerException to the constructor. See here: Anti-Patterns and the Solutions[^] especially the part "Error Hiding Anti-Pattern".

I would think hard before even trying to put a try ... catch block "inside" a foreach loop.
Exception handling can be expensive. If you were looping "thousands" of times, that would potentially mean "thousands" of exceptions.
An exception "inside" a loop, generally doesn't happen just once because the data / processing requirements are usually similar.
(IMO) One generally wraps a loop "inside" a try ... catch block; not the other way around; in which case, to "continue or not" is a non-issue. Repeated exceptions in a loop are a symptom of bigger problems that should be solved; not just "handled".
Exceptions are for "exceptions"; not general error handling.

In catch, continue will automatically work so no need to add the keyword there.
hi

But it is still a very bad (stupid) thing to do.
|
|
|
|
|
If one does not include the "continue" then execution will continue after the catch-block, not at the start of the loop.

Apart from what ever has been answered it is a good practice to catch the general exception also. In both the catch blocks you have to do 2 things log an exception as well as Display the exception to the user.
But my suggestion is if you can avoid exceptions that would be even better so have proper checks where ever required like null check etc etc.

Don't post the same question in two places - all you will do is duplicate work and annoy people. Pick either the C# forum or the Q&A and stick with it.

What have you done so far? What have you used to render the PDF to an image? Where, exactly, are you stuck?
It's important to remember that we can't see your code so we don't know what you've done or where you are having problems.

hi all,
i saw in this link:
https://msdn.microsoft.com/en-us/library/system.windows.forms.splitcontainer.orientation(v=vs.110).aspx
how to vertical container
my question is: how i do when i click iin button opened duplicate form but vertical???
thanks for all the helpers
|
|
|
|

Your question is not clear.
Creating a new Form is one task.
Creating a new Form and inserting a SplitContainer Control in it with 'Vertical orientation is another task.
Duplicating a Form ... creating a new version of a design-time specified Form ... is another possible Task.
Please describe exactly what you want to achieve.

i have a mdi form name "Main".
the mdi form include 1 form with container horenzial name "Sub"
i want to do a button on the Main form that open the "Sub" form as a new winform (not in mdi) and the container be a vertical
sorry on my bad English.
thank you
|

First, I'd define a public Property on your 'sub Form that allowed me to set and get the SplitContainer's 'Orientation property:
public Orientation CurrentSplitterOrientation
{
set { splitContainer1.Orientation = value; }
get { return splitContainer1.Orientation; }
}I'd use a public Property because I'd assume that I would want access the current value of 'Orientation, as well as set it.
In the Main MDI Form, you can "release" the MdiChildForm by setting its 'MdiParent property to 'null:
private SubForm1 subForm1 = new SubForm1();
private void Form1_Load(object sender, EventArgs e)
{
subForm1.MdiParent = this;
subForm1.Show();
}
private void button1_Click_1(object sender, EventArgs e)
{
subForm1.MdiParent = null;
subForm1.CurrentSplitterOrientation = Orientation.Vertical;
}I'd like to suggest you consider the following:
1. MDI architecture is now really out-dated, and if you have the choice, I suggest you don't use it.
2. Putting any Control on the MDI Parent Form itself, except maybe a ToolStripMenu, is generally a bad idea.
3. Changing a Form's status from being an 'MdiChildForm to being "just another" Form on the Desktop is ... well ... unusual. This may be confusing to your end-users. You might consider, instead of an MDI Parent to Child relationship, using the 'Owner property of the secondary Form ... set it to the Main Form, instead. A Form which has an 'Owner is guaranteed to remain in front of its'Owner Form.
