Re: Using CMFCStatusBar class How do you Set the Text for a Label(dynamically)

I noticed in MSDN under CMFCStatusBar that there is a SetPaneWidth() but How do you set a particular Pane's width using that command. if my pane is ID_PANE3 how would I set the width on it to fit the length of a CString? (I sure wished they would show examples of this stuff.)

Yes I see that; but If my pane is ID_PANE3 how would I get focus on it and do this CPane::AdjustSizeImmediate() . How do I set the length(not Width) to equal(in pixels) to a CString?
(An example would be great.)

What i'd try is to call that on the MFCStatusBar itself with TRUE as parameter, so something like:
my_mfc_statusbar.AdjustSizeImmediate(TRUE);

I find that using a function with various arguments uncovers a lot about its usage. Try something like:

mfcStatusBar.SetPaneWidth(ID_PANE3, 500);

It crashed because the ID_PANE3 is not supposed to be there, rather the nIndex of the Pane is supposed to be there. Works okay if set to 250 rather than 500. Thanks David.

They do, you just need to stop thinking that you will find a combined example for your specific needs.

Larry Mills Sr wrote:

That is one specific thing which is clearly depicted in the documentation for the class.

Larry Mills Sr wrote:

Finding the pixel width of string is an entirely separate subject that there are examples for. If you stop looking for combined examples and learn to break your problems down to the individual parts and solve each of them you might find you are more successful in the field of Software Development.

Also, stop using the word "command". Classes have methods, not commands. C libraries have functions, not commands. When you are using text based communications, applying the correct words is extremely helpful.

A Book shop maintains the inventory of books that are being sold at the shop. The list includes details such as author , title

, price , publisher and stock position. Whenever a customer wants a book , the sales person inputs the title and author and

the system searches the list and displays whether it is available or not. If it is not, an appropriate message is displayed. If

it is, then the system displays the book details and requests for number of copies required. If the requested copies are

available , the total cost of the requested copies is displayed ; otherwise the message " REQUIRED COPIES NOT IN

STOCK " is displayed.
Design a system using a class called books with suitable member functions and constructors. Use new

operator in constructiors to allocate memory space required.

Improve the sytem design to incorporate the following features :
a. The price of the books should be updated as and when required. Use a private member function to implement

this.

b. The stock value of each book should be automatically updated as soon as a transaction is completed.

c. The number of successful and unsuccessful transactions should be recorded for the purpose of statistical

analysis. Use static data members to keep count of transactions.

Modify the program to demonstrate the use of pointers to access the members.

Your answer does not fit the situation: the book shop hasn't opened yet, they await a good inventory control system. That is why it's urgent.

Are you looking for an urgent solution or do you need a solution
and the need is urgent?

I dug through my box of urgent solutions and sadly I don't have one
related to book inventory, sorry.
