You may use CDC::GetTextExtent(text) which gives you the size of the text in pixels if drawn with the currently CDC-selected font.

Yes, but I'm searching a general method to calculate the size of a font given a CRect and a text. There should be a relation between the size of the CRect in pixels and a given text to display in it (provided taht you have selected previously a font name)
Thanks

I'm not sure of that, because the font name is not enough. When a CFont object is constructed, the system tries to match the criteria you asked with the available fonts, and if it doesn't match, the system with get the closest font, which may be different from what you asked.
Another point is that DC characteristics need to be part of the calculations, 'cause font use logical units when you need pixel and this conversion is relative to the DC characteristics.
Anyway, if you can get this formula, I would be happy if you could share it, TIA

That ability may be exposed somewhere but I've not seen it.
I've resorted to constructing the desired font at various
point sizes and doing a binary search. It works ok since
I only need do this at the creation of the window wherein used.

how to i communicate between dialogs in a tab-control ?
my task is to notify another dialog to change its content
and notify the tabcontrol to show this other dialog and
hide the current.
i use the "CTabCtrlSSL - An easy to use, flexible extended tab control
By Derek Lakin"
has anybody an idea ?

I havn't looked at the example, but a guess would be to have each of the dialogs in your tab control to inherit from a base class one which provides a virtual function DoUpdate() or some such. This gets overriden in each of the actual dialog class's. Now to update the dialog in a different tab, you get your parent (the tab control) to give you a pointer to the required one, using this base class pointer. You then call DoUpdate on it.
To switch tot he other dialog, you should just call SetCurSel() or the equivalent on the tab control.

"WindowBlinds" does not use ModifyMenu or SetMenuItemInfo
and Menu is not with MF_OWERDRAW style.
How can it draw PopupMenu?
|
|
|
|
|
At a guess, they are ovvering the WM_DRAWITEM and WM_MEASUREITEM messages in the window that hosts the menu. THey do the drawing themselves there. The item does not have to be owner draw for this to work, I think.

Hi All,
There is a application which writes data into 3 databases
based on some conditions.
Database X,Y and Z.
X is registered in ODBC, I am not able to understand how application is writing into Y/Z
Can anyone explain me how to register Y/Z into ODBC

2) Write a C++ program which reads the names and ages of 10 people, and store these data in structures that are elements of an array. Print the average age of these people. Also, print a table of 10 lines, with on each line the given data of a person, along with the (positive or negative) deviation of his or her age from the average age. store only the first 30 characters (followed by the null character) of names that are longer than 30 characters. Be sure to incorporate into your program the use of classes, private data, public function process data, constructors and destructors where appropriate.
Notes: must use object oriented
Notes: have choice * ask how many people would you like to enter data for.
Thanks, Alisha

Hi Alisha. Welcome to CP. This is a community of developers who love to help each other. Sadly, it appears we cannot help you. I could write this inside of 15 minutes, but if I did, how would it help you ? Your teachers assume they have given you enough information to do this problem, and certainly enough exists on the web and in books as well. In fact, I can think of a number of CP articles which between them would tell you all you need to know. If I did this problem, then you would have no idea how to do your next assignment, which would build on the skills you were supposed to build in writing this one. At what point do you propose to learn for yourself ?
Both myself and the rest of this online community will fall over themselves to offer advice if in trying to write this assignment you get stuck somewhere, but no-one is going to do your homework for you. One day, you may live to thank us. The alternative is that you'll be cleaning the swimming pool of someone who did their own homework.

That is one of the most comprehensive and gentle responses I have ever seen on this site to a "please do my homework for me" question. Thank you for setting a high standard for the rest of us to follow. I intend to emulate, to the best of my ability, the model behavior you have established, and I encourage the rest of our members to take notes, and refer to them often.

*blush* Thanks for noticing. I am working very hard to put down my sarcastic side and to make sure that the way I talk to new members in particular is reflective of what a great place this is. I've talked a lot about the danger we have of becoming insular, and I'm trying to act in accordance with what I have said. It's worried me a lot lately that particularly newbies posting questions in the lounge seem to get tarred, feathered and run out of town. And of course homework questions are our second pet hate. But who hasn't posted something inappropriate somewhere as a newbie ? I'd rather get the chance to help this person and see them become a CPian than to feel smug that I showed them who is boss.

While you're in such a good mood, you should gently help out "jirigala" (user #98406) who posted the same question in all these articles

You're doing a great job of it, and (I hope) setting a good example for the rest of us.

That's a great danger to a site that is growing at the pace CP is experiencing, and a pitfall that we need to avoid. Those of us who have been around since the beginning are bound to feel threatened by the changes, but we need to grow with them, not oppose them. It's not the same elite club it used to be, and we need to adapt accordingly.
Christian Graus wrote:

We all have, I think. My one and only article, so far, was posted only out of a feeling of obligation to contribute something to the site that has given me so much. It's relatively worthless, but it solved a problem my employer needed solved, and it was all I had on tap to offer at the time. I hope that someone else has found it useful, but I strongly doubt it. If my submittal had been met with ridicule and abuse, however, I would have never visited again. We need to keep that in mind when we find a newbie in our midst - we don't want to run off any gems in the rough, and the trend lately has been rather hostile.

Yeah, I know the feeling... It's fun, but transitory. Better, much I think, to suffer in silence a few youthful indiscretions, than to lose a potentially valuable member of our community.
Thanks, again, for setting a standard I'd like to emulate...

Maybe Chris should add an option under each thread near [Reply], like [Homework], which would automatically reply an answer like the one Christian wrote.

1) A gas station has two pumps. Cars arrive at an average rate of 24 per hour. The service time for each car is either 3,4,5,6, or 7 minutes each with probability 1/5. Simulate the operation of the gas tation for 8 hours using a one minute time interval. Assume that a car arriving when both pumps are occupied drives on. Determine and print out the fraction of customers lost, in addition to the number of customers served and the total number of arrivals during the 8 hour period.

Looks like a pretty simple problem - where are you stuck ?

1. assume the student doesn't do the homework.
2. predict the grade on the final.

This is a forum for ppl wanting solutions for Visual C++. Not to answer something that looks like as if it was copied straight from an assignment sheet.
If it was an assignment or test.. shame on you.
