Need help in vb

[csKanna]

I had a test recently. in that test asked me the following question:

You have a picture of each employee stored on a network drive in JPEG format, with the path stored in a text field in an Access Database. You want to display this picture on a form in your VB application. Which one of the following correctly displays the picture as described in the scenario above?

Choice 1
An image control updated through code

Choice 2
An image control box bound to the database table and field

Choice 3
A unbound OLE Object control updated through code

Choice 4
A user-defined hyperlink control linked to the table and field

Choice 5
A picture box control bound to a data control

somebody help me on this pleae

First, im surprised that with about the same amount of posts as I have, you are still getting away with posting such vague titles. Please make it more specific in the future :P

Anyways, I believe its just an image control updated through code. I mean, sure its a complicated example, but ... its still just an image box that you are changing... flame me if I'm wrong

EDIT: I see you also have user input... looks like it could be hte fifth choice then.

I couldn't agree more!


Right then, on to answering the question..

Is the picture in the database? If it is, then you could use a bound control (I would personally use code, but based on the question, it seems you aren't at this level yet). If it isn't in the database, the control cant be bound.

Will a hyperlink show the picture on your form?

Once you have answered my two questions, you are down to two possible answers, one of which you should be able to eliminate quite easily.

Hi si_the_geek,

I do not have answers to your questions, since this is the question in my exam. I do not know the answers. So, i thought i should ask some experts like you.

If anybody know the answer, please help me to learn.

[si_the_geek]

The answer to my first question is in your original post.

The answer to my second question needs an understanding of what a Hyperlink is.


Tell us which options you can eliminate, and why - if necessary, we can explain where you have gone wrong.

[csKanna]

As per the quest.the pic is saved on a network drive and not in a database. Only the path is stored there. In such a case there will be no help of a bound control. Hence I eliminate choice 1 of your ans.

Now the probability lies in next one . I think hyperlink will show the picture.

Although,I do not have any idea about Hyperlink.

If I am correct so far than I think we can move further.

Thanks

[si_the_geek]

You are right about the location of the picture - which eliminates 2 of the choices.


Time for a quick hint on the other part...

This is a hyperlink: search.

This is a picture:


Now which choices remain?

[csKanna]

Its the second choice. Am I correct?

[Pradeep1210]

No, it's the First one!

[si_the_geek]

Its the second choice. Am I correct?

If you mean the second option from post #7, then you are correct.

If you mean from the original choices (which is what I was refering to) then read your own posts again - you have already said it cant be that one.

[csKanna]

Do not confuse me again and again. I am tired. Please tell me the correct solution to my question on post #1. thanks.

[si_the_geek]

I am not trying to confuse you - I have been telling you how to work out the answer, which is an essential skill.. not just for exams/tests, but also (to a much greater level) for programming, and many other careers.

Read the first line of post #6 (yours), which eliminates a few of the choices (possible answers to the original question).

As I showed in post #7, a hyperlink is not a picture.


Which of the original choices now remain?

[csKanna]

So,

May i conclude this topic by assuming choice 4 as the answer to my question

Thanks.

[si_the_geek]

No, as a hyperlink is not a picture.

This (and the knowledge you have from above) should leave only two choices.. and of those two similar choices it should be fairly clear which one is more appropriate.
