Hello. I'm making a small game with MFC and I need to animate a bitmap to move around the screen and bounce off the edges. I'm using BitBlt(), and my only problem is that the image leaves a trail of itself behind it when it moves, and it's irritating because I've tried everything I can think of to fix it. Any help would be greatly appreciated. Thanks.
Brendan

Use dubbel buffer, Memory DC
CClientDC dc(this);//Get a valid DC
CDC memDC // for dubbel buffer
memDC.CreateCompatibleDC(&dc); creates a valid CDC in memory
memDC.SelectObject(&m_bmp); //adress to a CBitmap Object;
//this bitmap will be your Dubbel Buffer
BITMAP bm; // Bitmap STRUCT
m_bmp.GetBitmap(&bm); // Get info of the Bitmap width height
//now the trick
//Blit your Bitmap in to the memmory;
memDC.BitBlt(0,0,bm.bmWidth,bm.bmHeight,&YourBitmapDC,0,0,SRCCOPY);
//Then show the result in the Window DC
dc.BitBlt(0,0,bm.bmWidth,bm.bmHeight,&memDC,0,0,SRCCOPY);
//this is not so fast take a look att the Dib classes on CP
//OR some DirectDraw surface class

I still find that people esp. long time VC6 users are confused with the VS.NET IDE. Should we have an article on it as to where to find what, how to do something in VS.NET ...

how to do xxx in VS.NET
Sorry but so far I have found no way of producing pron using VS.NET. I loved that feature in VS6, wish they would bring it back...
Sorry could not resist.
Actually that is a good idea (the article, not the xxx.) Definitley an article that will need colaboration though, not something one (wo)man alone can do.

Would anyone be interested in a series of articles covering the development of a website, from start to finish?
It would include:
- Requirements gathering
- Analysis & Design
- Graphic Design
- Project Planning
- Front End & Back End development
- Testing & Stabilisation
- Launch
If yes, then are there any other sections in the life cycle of a web project you want covered?
It will be using the following tools and technologies:
- Microsoft Word and Visio
- ASP.NET
- XHTML & CSS
- XML & XSL
- JavaScript
- tSQL
and the site would involve:
- Content management
- Forums & Community
- Forms development
- Email services
- Repurposing content for different devices (e.g. to PDAs)
It is a pretty mammoth task and something I have been wanting to do for awhile. So before I dive in I wanted to see if anyone is actually interested here on CP, or whether I should just be writing it for myself and co-workers.
Also at what level do you want it pitched? Beginner, intermediate or advanced? And if anyone is interested in helping out with certain sections, just email me.
thanks

Guess it's a very good idea.
The level should be - i think - intermediate, and it could establish strong accents on:
- Requirements gathering
- Analysis & Design
- Project Planning
Wish you good luck!

Yes please.
I'd pretty much consider myself a beginner when it comes to web-site building but can bullshit my way through HTML based conversations.

Somewhere beyond the html stuff...
"CodeProject-like site-HOWTO-with-file-browsing-forums-and-so-on" would be nice though

I'd be interested in seeing it done. I've done a few small sites; but nothing beyond master/detail type stuff.

On MSDN, look up "Reference Architecture for Commerce".
They have a series of "Articles" (really a book) on designing, testing etc a web site.

Yeah thanks. I have been through that awhile back. Problem is they are very much not up to date on things like CSS and XHTML (which I do want to cover as it is impotant.)
Also they can be a tad impractical at times and focus solely, obviously, on MS tech such as Commerce Server (which not everyone can get their paws on.)
But it is a good base to work from indeed

Sounds great Paul! It wasn't clear to me though whether you're creating a new community site, or developing articles for posting here, or somewhere...

I have to a web search for a program for a school web search project that matches the question below.Can anybody give me a program or tell me where I can get one that matches this question in C not C++ please.
If so e-mail is speedster264@hotmail.com.
Many thanks.
Here Is question.
A small shopkeeper uses a simple computer system to keep an up to date inventory of all products stocked. Every week the shopkeeper updates the stock file with a series of stock amendments, stored on another file. The format of both TEXT FILES is shown below, with each record stored in ascending order of product code, and each field being separated by a comma. Both files tenninate with a special "sentinel" product code of 9999.
Stock File.
Product Code 4 digits
Quantity 4 digits (in the range 1000 to 9999)
Buying Price 4 digits
Sale Price 4 digits
Stock Amendments File.
Product Code 4 digits
Amendment Type 1 character 'I' for an issue from stock.
'R' for a receipt into stock.
'B' for an amendment to the buying price.
'S' for an amendment to the sale price.
'D' for a deletion of the stock item.
Value 4 digits
NOTE
The data item "Value" will be zero in the case of a stock item deletion.
Find a program that will update the existing stock file, creating a new stock file, in the
same order as the original. It is possible that a stock item will have one, more than one,
or no transactions during a week. After the update of a master record, any stock item
that is outside the given range should also have the record written to a "query file".
You can assume that there are no transactions in the stock amendments file that do not
have matching product codes in the stock file.

do you think we're here to do your homework ?

Not asking for you to do it ,,,just need a program that answers it or as close to answer as possible.

If you replace "Find a program" with "Write a program", it looks awfully like a Programming 101 homework question.

how can i use the windows installer SDK?, i would like an article about it, i have read some on msdn but i cant understand it well.
|
|

Hmm, well it will be nice. But if you want a small hint, use Installer "msi"s like a usual databases. You can run SQL statements against them, and the structure is just tables which holds all information. You can even create your installer manually, without using tools like InstallShield, although they are making life easy
