Folderbrowserdialog Unmasked: Everything You Wanted to Know About the Folder Browser Component From .net Framework
Original Article :http://www.ssware.com/articles/folderbrowserdialog-unmasked-everything-you-wanted-to-know-about-the-folder-browser-component-from-dotnet-framework.htm
Introduction
The FolderBrowserDialog, available as part of the .Net framework, provides a folder browser component for your C# and VB.Net applications. The UI consists of a modal dialog which contains a tree control displaying all the files and folders on the system. The user can then browse and select a folder from the tree. The full path of the selected folder is then returned.
Basic Usage
To display a folder explorer UI to the user, a FolderBrowserDialog instance is created and the ShowDialog method is called. This shows the modal dialog containing the folder browser control (tree) and an OK and Cancel button. If the user selects a folder and clicks the OK button, the ShowDialog method returns DialogResult.OK and the SelectedPath property contains the full path of the selected folder. If the user clicks the Cancel button, the ShowDialog method returns DialogResult.Cancel.
Advanced Usage
The FolderBrowserDialog has some additional features such as limiting the view of the file system that is displayed to the user, pre-selecting a folder when the dialog is first displayed and displaying a button to allow the user to create a new folder.
The RootFolder property can be set to the full path of the folder which is to be displayed as the root of the tree control of the folder browser component. For example, if this property is set to Environment.SpecialFolder.Personal, only folders from the 'My Documents' are displayed in the tree, so the user can only select 'My Documents' or its sub-folders.
Prior to displaying the folder browser control, the SelectedPath property can be set to the full path of a folder causing that folder to be pre-selected in the folder browser tree. For example, when this property is set to "c:", the node corresponding to the c: drive is pre-selected in the tree when the dialog is first displayed.
If the ShowNewFolderButton property is set to true, then, in addition to the folder browser tree control, and the OK and Cancel buttons, the folder browser dialog also displays an additional 'New Folder' button which when clicked, creates a new folder under the currently selected folder.
Limitations
While the folder browser component is a handy way to allow the users to browse and select folders, it suffers from many limitations, some of them preventing the component from being of practical use in applications.
Modal Functionality
The folder browser component of the most obvious drawback is that it is displayed in the form of a modal dialog user interface. Displayed, it will prevent the rest of the application until the user selects a folder. As long as the dialog box is displayed, there is no input (keyboard or mouse click) In addition to occur in the dialog box. The user must input may appear before the caller identification or the Cancel button.
This is a very annoying and limited FolderBrowserDialog function. Users are likely to be irritated, and tired when they interact with a modal dialog box each time they want to explore and select a folder. A non-modal user interface controls can be the application itself is a form or dialog box, which is a more user-friendly display of the same user-friendly way.
No Virtual (Non-file system) folders
The FolderBrowserDialog does not allow the user to select virtual (Non-file system) folders such as the Control Panel or My Computer. It only allows the user to select a file system path such as "c:" or "c:windows".
No Files
The component does not allow the user to select files. This is a major drawback since there are many circumstances where the user may need to select a file while still using the tree UI to browse to that file.
Limited Choice of RootFolder
The root folder of the folder browser control can be only set to one of the 'special folders' defined by Windows such as the 'My Documents' or 'My Computer'. This is a major limitation since this means you cannot set the root folder to a path such as the "d:" drive.
No Check Boxes
The folder explorer tree in the FolderBrowserDialog cannot show check boxes next to nodes. Ability to show multi-state check boxes can be a very handle feature for such a control.
No Filtering
The FolderBrowserDialog has no support for filtering. For example, it is not possible to display only network folders or only shared folders or only folders starting with the string "Documents" or files having a particular extension.
No Custom Controls
When using FolderBrowserDialog, you are only limited to the actual folder tree control manager to identify, cancel, and the New Folder button and description tags. This is a can not add custom control dialog box. This will be useful, in many cases, such as when you want to display thumbnails / preview of the selected file / folder, or any other relevant information.
No Appearance Control
The appearance of the FolderBrowserDialog and its constituent controls cannot be changed. Neither can attributes of individual folders show in the folder explorer control be changed. For example, it is not possible to change the background color of the tree control or to set the font and color of individual nodes/folders in the tree.
No Custom items
The FolderBrowserDialog cannot display external/custom items in the folder explorer tree. For example, it may be necessary to display items from an FTP location in addition to the file system items. This is not possible with the FolderBrowserDialog.
No Lockdown
The FolderBrowserDialog operations can freely Folder. The user can rename the folder, go drag
Beyond The FolderBrowserDialog : The FolderView Control
The Folder View Control brings a Windows Explorer-like folder browser component to your applications complete with AutoUpdate, dragdrop, icons, context menus, non-filesystem items, default key-handling, info tips and rename. It features powerful behavior control and customization functionality takes it miles ahead of Windows Explorer by adding features like filtering, checkboxes, custom items, more than one root node, dragdrop control and customization of default context menus, display names, icons and more tips.
The FolderView control is a UI control which can be dropped right inside your own forms and dialogs. A non-modal file & folder browsing/selection experience right inside your own dialogs and forms is something that users will appreciate and find intuitive and simple.
Additionally, FolderView overcomes all the limitations of the FolderBrowserDialog and provides far greater and advanced features and functionality than the FolderBrowserDialog. The following table is a quick comparison of the FolderView Control with the FolderBrowserDialog.

Job Interview Question: Prepare for the ONE essential!
Do not you wish you every interview question would go exactly as you predicted? You know, the interviewer asks questions exactly as you imagined?
Unfortunately, that rarely happens. You must be ready for anything. This means that you have to think about alternative strategies. And is prepared to answer questions, you can not expect.
But after all is said and done, there's only ONE essential that will finally make the difference in terms of your candidacy.It overshadows everything else that may happen in the interview.
You will move forward to the next step only if the interviewer likes you!
That's right! Ultimately, when you are interviewed, are less convincing on the interview you can do the job but to convince you the kind of person he wishes. That means you like it!
So, how do you do that?Here are some tips to keeps in mind:
1. Enter the room with a smile.Look the interviewer directly in the eye.Extend your hand for a firm handshake.
Two. Please prepare to relieve a friendly comment. What was that about. . . Weather, sports events when or where the travel office, or a BBQ last night, what you eat and your pets
3. Let the interviewer control the pace and discussion climate.
Four. Meanwhile, all the questions just do not sit passively like a bump, please answer the way you walked. Then you turn it on in the dialog. Please prepare intelligent questions.
5. Be ready to answer objections without getting defensive.Identify in advance where your weak spots are and practice a comfortable answer.
Once again, remember if you move a job or to the next step depends very much on how much the interviewer like you. Of course, your qualifications to the job are important.
But remember, you were invited to the interview because someone has checked the background and decided that it would be worthwhile to speak. So your main task is to make youreself likeable!

Accepted, will appear in an interview for a possible job, is an exciting time in every life. Having applied for and accepted is a step in the right direction, and the proof that everything that you will be able to fulfill it that employer's expectations. As we prepare for what comes next is essential, so make sure you with the knowledge of what could interview candidates questions are raised, are the way to the interview armed.
Interview includes questions of the candidates in general:
- The background on your experience
- What studies you may have completed
- Where your future interests lie
It is best to come across as natural as possible, confident but not pompous, friendly but not casual. If you are well equipped with relevant expertise in your chosen field, then you should be able to talk about your capabilities with ease. Studies don't necessarily mean the difference between getting a job or not, in fact many people land exceptional employment opportunities just by having the appropriate experience and a level head on their shoulders. However, often times, candidate interview questions presented by the interviewer will include your background studies and if these are in anyway significant to the?jobs?you are applying for, then make mention of it as it can only boost the impression you put forward.
In many cases, online recruitment companies will ask you questions such as personal interviews of candidates:
- How do you think you will add value to this company?
- How would you handle a difficult customer?
- What would you do to resolve a dispute between employees?
All of these candidate interview questions hold a lot of value in determining whether or not you will fit in with the company ethos and as a part of their team. It is pointless recruiting?a person who is completely apt in terms of experience and qualifications, but who doesn't communicate with other employees and treats customers disrespectfully. This plays an important role in companies that are highly customer centred where a friendly, outgoing nature would be an important asset for the candidate. Conversely, if the company culture as a whole is one of quite professionalism candidate interview questions such as those presented above will ascertain whether a candidate is perhaps too outgoing and sociable to add value to the company.?
The evaluation is to bring to the forefront of your positive attributes, and should not be afraid and brilliance. What is required to either, but you do not, you do not know if there is no try.

Posted in: interview questions| Tags: Interview job time step everything employer proof direction lifeGood Interview Questions to Ask at Interview
?
Most interviewees focus only on what interview questions are asked of them and what answers they should give.
Few enough attention to what questions they should ask their interviewers us!
But you must have at least one good interview question to ask. Why?
Because if you do not, your interviewer may have a negative thinking of one of the following:
They will think that you think you know everything about the job / company already, if they know that you do not (how could you if you already do the job?).
They will think you are a suitable job is not an option, because you would accept that it does not ask any serious position on the issue.
So always have at least one good interview question to ask your interviewer/s.
Here are some ideas if you’re stuck.
Questions about the Company
What can you tell me about the Company’s plans for the next 5 years?
What is the Company’s main focus this year?
What’s the best thing about working for the Company?
What does the Company pride itself on?
How would you describe the Company ethos?
Questions about the role
In addition to what we discussed, what other activities undertaken by me in this role?
What plans do you have for this role, moving forward?
How many others do the same role as this?
Has the role changed since it first began?
Questions about training
Can you tell me how I’ll be trained? Will it be on-the-job for example?
How long do you expect it to be before I’m fully competent in the role?
Who will train me? Will it be a colleague doing the job already?
Questions about progression/development
What is the progress of opportunity in order for me, if I succeed, this role?
Does the Company promote development for its staff?
Have you benefited from progression in this Company?
Questions about performance measurement
How will my performance be measured in this role?
What rewards are there for those who out-perform their peers?
How often will I be appraised?
You may have noticed that some of these good interview questions are personal questions for the interview. Do not be afraid to ask them. It shows that you see your interviewer / s as workers and very interested in the experiences and views. This creates a friendly, warm environment that can only work in your favor.
Note: Don’t ask NO questions but don’t ask TOO many questions either. Your interviewers’ time is previous so only ask those questions which will affect your decision to accept the job if it were offered to you. Stick to a maximum of 5 questions, less if time appears short.
