Interview Questions.

Q1. How Do I Pin All The Files Within A Project?

You can do this using the command-line pin parameter and the wildcard person for the report name.

For example: SS PIN $/MyProject/*.* -VLver1

Q2. How Do I Find All Changes Between Two Dates?

Here's the way to get a list of everything that has modified given that a specific date and time from the command line. In the command "a" or "p", refers to a.M. Or p.M. Respectively. And the ~ is used to signify you need the history between the dates and times precise. Note that the later date and time ought to be precise first. -R makes it recursive. SS HISTORY $/mybranch -R -VD3/03/ninety five;three:00p~3/03/ninety five;nine:00a

Q3. Does Vss Ole Automation Support Label Comments?

VSS 6.0 absolutely supports label remarks. Label comments, however, aren't available in VSS five.Zero.

Q4. Where Can I Find The Ssscc Api?

Microsoft discourages using the SSSCC API. Instead they advocate you use the OLE Automation interface. 

However, in case you nevertheless desire to use the API you can request the MSSCCI spec by way of writing to msscci@microsoft.Com. They will send you the NDA you need to sign to get the spec, and then ship you the spec.

Q5. Is It Possible To Trap File Deletions And Rollbacks Using An Add-in/vss Ole Automation?

These activities are not supported as of this posting with the aid of Rich Knox of Microsoft: Trapping Rollbacks/Deletions.

Q6. How Do I Remove A Label?

This one is not intuitive. From inside VSS Explorer, select the task, show records, check Labels Only, locate the label of interest, click on Details, pick out the label text and delete it. Click Close, if you want to ask in case you are positive you need to change the label. Click Yes and you are executed.

Q7. How Do I Select A Database From The Command Line?

You can set the SSDIR environment variable to point to the region of the database's SRCSAFE.INI file. • Chuck Kollars discusses the tradeoffs of a unmarried vs multiple databases at his website.

Q8. Does Vss Ole Automation Support Administrative Functions?

VSS 6.Zero supports a few administrative functions.

Q9. How Does Cvs Work?

CVS saves its model-control statistics in RCS documents saved in a listing hierarchy, known as the Repository, which is separate from the user's operating directory.Files inside the Repository are saved in a format dictated by using the RCS instructions CVS makes use of to do plenty of its real work. RCS files are standard byte-stream documents with an inner format described by way of keywords saved within the files themselves.To start paintings, you execute a "checkout" command, handing it a module call or listing course (relative to the $CVSROOT variable)you need to paintings on. CVS copies the brand new revision of each report inside the precise module or directory out of the Repository and into a directory tree created for your modern directory.

You may additionally specify a particular branch to work on with the aid of symbolic call in case you do not want to work on the default (principal or trunk) branch.You may also then regulate files inside the new listing tree, construct them into output files and take a look at the effects.When you need to make your changes to be had to other builders, you "dedicate" them lower back into the Repository.Other developers can check out the equal documents at the identical time.To merge the committed paintings of others into your operating documents you use the "update" command. When your merged documents construct and check correctly, you may commit the merged end result. This technique is called "reproduction-alter-merge", which does not require locks on the source files.At any time, usually at some milestone, you may "tag" the devoted documents, producing a symbolic call that can be surpassed to a future "checkout" command. A unique form of "tag" produces a branch in improvement, as usually occurs at "release" time. When you no longer plan to alter or consult with your nearby reproduction of the documents, they can be eliminated.

Q10. How Do I Apply A Label To An Older Version Of A File?

You ought to first pin the file on the older version (Show History, select the model of hobby and click on “Pin”.) Then follow the label to the discern project. The label can be applied to the “tip” revision of the unpinned documents, however to the older version of pinned documents. Then Unpin the document. The label ‘sticks' even after the pin is eliminated.

Q11. How Does Cvs Differ From Sccs?

SCCS is much towards RCS than to CVS, so some of the previous access applies.

Q12. How Do I Retrieve The Comment From A Specific Version Of A File?

This requires that you iterate through each model of the record looking for the label you need. Once the perfect model of the record is diagnosed you can retrieve the remark for that version. Below is some sample VB code demonstrating this: For Each ob VSS Version In ob VSS  Object.Versions If objVSSVersion.Action = "Beta 1" Then MsgBox(objVSSVersion.LabelComment) End If Next

Q13. What Is A Branch?

In widespread, a branch is any mechanism that allows one or extra builders to alter a record with out affecting every body other than the ones running on the equal branch.

There are four types of "branch" CVS can control:

@The Vendor Branch. A single dealer department is supported. The "import" command takes a sequence of releases from a supply code seller (known as a "dealer" despite the fact that no money is involved), placing them on a special "Vendor" branch. The Vendor department is taken into consideration part of the "Main line" of improvement, though it need to be merged into domestically modified files on the RCS Main branch earlier than the "import" is whole. See Section 3H ("import").

@Your Working directory. A checked-out operating directory, may be handled like a non-public branch. No one but you may contact your files. You have complete manage over when you consist of paintings committed through others. However, you cannot commit or tag intermediate versions of your paintings.

@A Development department. A organization of builders can proportion adjustments many of the group, with out affecting the Main line of improvement, by means of growing a branch. Only the ones who've checked-out the department see the modifications dedicated to that department. This sort of department is commonly temporary, collapsing (i.E. Merge and forget about) into the Main line whilst the venture requiring the department is finished. You also can create a private department of this type, permitting an individual to commit (and tag) intermediate revisions with out changing the Main line. It should be controlled exactly like a Development Branch -- collapsed into the Main line (or its discern branch, if that isn't the Main Branch) and forgotten when the work is executed.

@A Release branch. At launch time, a branch have to be created marking what changed into launched. Later, small modifications (now and again referred to as "patches") can be made to the release with out such as everything else at the Main line of development. You keep away from forcing the customer to simply accept new, in all likelihood untested, features introduced since the release. This is likewise the way to correct insects discovered all through trying out in an surroundings in which other builders have continued to decide to the Main line while you are checking out and packaging the discharge. Although the internal format of this form of branch (department tag and RCS branches) is the same as in a development department, its motive and the way it's far controlled are special. The important difference is that a Release branch is generally Permanent. Once you let a release out the door to customers, or to the next stage of something system you're the use of, you must preserve forever the branch marking that release.

Since the branch is everlasting, you can not comprise the branch fixes into the Main line with the aid of "collapsing" (merging and forgetting) the discharge branch. For big changes to many documents on the discharge branch, you'll should carry out a department merge the usage of "replace -j -j ". (See 4C.7) The maximum common way to merge small modifications returned into Main line development is to make the change in both locations concurrently. This is faster than seeking to carry out a selective merge.

Q14. What Is Cvs For? What Does It Do For Me?

CVS is used to keep music of collections of files in a shared directory called "The Repository". Each collection of documents can be given a "module" call, that is used to "checkout" that series. After checkout, documents may be modified (the usage of your favourite editor), "dedicated" returned into the Repository and as compared towards earlier revisions. Collections of documents can be "tagged" with a symbolic name for later retrieval. You can upload new files, remove documents you not need, ask for statistics about units of documents in three exclusive methods, produce patch "diffs" from a base revision and merge the dedicated adjustments of other builders into your operating documents.

Q15. How Does Cvs Differ From Rcs?

CVS uses RCS to do a lot of its work and without a doubt all the paintings of changing the underlying RCS files inside the Repository. RCS incorporates a hard and fast of programs designed to keep track of adjustments to man or woman documents. Of direction, it also permits you to consult more than one files at the command line, but they're dealt with with the aid of iterating over person files. There is no pretense of coordinated interaction amongst businesses of files. CVS's principal motive is to offer a hard and fast of grouping functions that will let you treat a collection of RCS files as a single item. Of course, CVS also has to do quite a few iteration, however it tries its nice to cover that it is doing so. In addition, CVS has some certainly group-orientated aspects, including the modules report and the CVS administrative documents that consult with a whole listing or module. One institution thing that may be a piece puzzling is that a CVS department is not the same as an RCS branch. To aid a CVS department, CVS uses "tags" (what RCS calls "symbols") and a few neighborhood country, similarly to RCS branches. Other capabilities supplied by means of CVS that are not supported without delay through RCS are @Automatic willpower of the kingdom of a document, (e.G. Modified, up to date with the Repository, already tagged with the identical string, etc.) which enables in proscribing the quantity of displayed textual content you need to struggle through to figure out what changed and what to do next. @A replica-regulate-merge scheme that avoids locking the documents and permits simultaneous development on a single file. @Serialization of commits. CVS requires you to merge all adjustments devoted (thru "update") since you looked at your operating replica of the report. Although it is nonetheless possible to devote a report packed with vintage facts, it's far much less in all likelihood than while the use of raw RCS.

Q16. Define Dom?

DOM is a platform impartial, World Wide Web Consortium (W3C) preferred shape of illustration of established files as an item-orientated model. It is an software programming interface so that it will get admission to HTML and XML files.

Q17. Where The Document Object Model (dom) Is Used?

Document Object Model (DOM) is used to query, traverse and manipulate files like XML or HTML files. DOM is quality desirable in which the report have to be accessed again and again or out of sequence order. DOM lets in getting access to the contents of a web web page. It additionally permits coping with events that lets in shooting and responding to person's movements. There are one-of-a-kind degrees of DOM requirements depending on the compatibility of the browsers.

Q18. List The Features Of Dom?

DOM is Document Object Model. It is used to study records from a XML report. It is more usually used in programs wherein statistics in the file desires to be repeated accessed. DOM supports navigation in any route. XML DOM is normally used for XML documents. The DOM defines the items and residences of all record elements, and the strategies (interface) to get entry to them.

Q19. Define Xmlhttprequest Object?

The XMLHttpRequest item is used to connect to the server through http. Scripts use it to accomplish that programmatically.

The EventTarget interface needs to be applied if an object implements the XMLHttpRequest interface. Also, an XMLHttpRequest() constructor wishes to be furnished through objects that enforce the Window interface.

Q20. What Does Cvs Stand For? Can You Describe It In One Sentence?

"CVS" is an acronym for the "Concurrent Versions System". CVS is a "Source Control" or "Revision Control" device designed to maintain song of supply modifications made by means of agencies of builders operating on the identical files, permitting them to live in sync with each different as every man or woman chooses.

Q21. Explain The Difference Between Dom And Sax?

SAX parser works incrementally and generates activities which are surpassed to the software. DOM parser reads the entire XML report and returns a DOM tree representation of xml report

In DOM the xml document is arranged as a tree and back and forth search is possible In SAX traversing in any route isn't always possible as Top to backside method is used.

SAX is essentially an API for analyzing XML, and now not writing it. DOM allows you to study and write.

Q22. Define Html Dom?

The HTML DOM API specializes and adds the capability to relate to HTML files and elements. It addresses the troubles of backwards compatibility with the Level 0 of DOM and provides mechanisms for not unusual and frequent operations on HTML files.

Q23. How Do I Get With Respect To A Label?

Need to use the '-v' transfer with an 'L' after it to suggest a label (-R is for recursive): SS GET $undertaking -VLmy  label -R
