I check the WM_KEYDOWN message in the PreTranslateMessage() handler...

WM_KEYDOWN does NOT return ASCII characters. It returns virtual-key codes for the keys which happen to be ASCII characters for some of the keys.
The TranslateMessage function looks for WM_KEYDOWN messages and if it can convert the data in that message to a character-code (ASCII codefor ASCII keyboards???) then it generates a WM_CHAR message.

I'm going to patent thought. I have yet to see any prior art.

i really need help writing this program:
In this assignment, you will creating a simple interactive guessing game, which is based on random numbers. The game is simple: two dice are rolled; you need to predict whether the sum of the next roll will be higher or lower than the previous roll. For example, you may have the first die roll a 2 and the second die roll a 3. The sum of this roll is 5. Statistically speaking, you should "predict" higher because the average roll results in 6. If the roll is higher than or equal to 5 and you predicted it to be higher, then you get to continue. If the roll is lower (or equal to) and you predicted lower, you get to continue. Basically a wrong prediction will end the game.
Background: This program could potentially play forever (though it's doubtful), so obviously you need a loop of some kind - but choose carefully.
Requirements: Basically the program should behave as closely to the example below as possible; the grade breakdown is roughly as follows:
For a 'C': Get the program to roll the dice once, ask if the next roll will be higher or lower, roll the dice again and say if it was correct or not.
For a 'B': Get the program to repeatedly do this until they guess wrong
For an 'A': Get the program to track the number of times the user guessed correctly
 can some1 plz plz help me

I'm happy to do this for you, I'll have it done in about half an hour. I'll charge $20. When you get your next assignment, you'll have no idea how to do it, because it will build on the knowledge you should have build with this program. So, my price will double. By the time you graduate, you'll know nothing, and I'll have bought a house.
OR, you could start on this project yourself, with reference to your course notes and whatever books you have. Then, if you get stuck and ask specific questions here, I'll help you gladly, for free.

Hi again. YOu emailed me as follows:
ok i have started the project on my own so after i put the basic skeleton i put (int userchoice = ??) i dont know what to put there so can you help me?
erm... I meant to do more than get the wizard to generate a skeleton. Why not post your code ? If you're yet to write any, look into cout and cin.

hi, all
the program I am working on returns a 7 digits value for cycle number, it should be 1-99, i am trying to find out where it gets this value, i set some breakpoints, it has the right value 02 at the beginning, at the end of the onPaint() function of dlgMain.cpp, it will go to next function void CMainWnd::OnOK(), the 1243994 as value show up, it looks like some sort of memory location to me, but seems like between these two function are all disassembly stuff, i couldn't really read them.....looking at call stack, still can't find it stop at which file to get this value either...
anybody has any idea? thanks for your time.

Simplest way debugging is to show messagebox containg the values at the point you think there is problem.

how can i get the md5 hash of something in mfc
|
|
|
|

google - there are plenty of MD5 examples available online.

thats what i am doing write now... but all i am finding is forums about ppl asking what php's md5() function is for...

First hit[^]
You need to think about what you type into google. I typed md5 C++ source code. md5 by itself would obviously get a lot of other hits.

Any set of C functions would integrate nicely with MFC. Here's[^] one C-implementation. All you have to do is to copy'n'paste, and you're set.
char text[] = "your text here";
md5_context ctx;
md5_starts(&ctx);
md5_update(&ctx, (unsigned char*)text, sizeof(text));
unsigned char md5hash[16];
md5_finish(&ctx, md5hash); There you go! Please note that the contents of md5hash will be in binary format. It's not a string, it's an array of exactly 16 bytes. If you need to convert it into a string, then you'll have to do something like this:
char hashtext[33];
for(int i = 0; i < 16; ++i) {
unsigned char hinibble = ((md5hash[i] & 0xF0) >> 4);
unsigned char lonibble = md5hash[i] & 0xF;
hashtext[i * 2] = hinibble >= ? (hinibble - 10) + 'A' : hinibble + '0';
hashtext[i * 2 + 1] = lonibble >= ? (lonibble - 10) + 'A' : lonibble + '0';
}
hashtext[32] = 0; hashtext will now contain the hash on a hexadecimal form.
Also note that the input can be any kind of data, it doesn't have to be text! Any byte chunk would do.

I've had an md5 implementation here on Codeproject for years and years. It works fine, although its pretty old fashioned code. There are several other MD5 examples here.
You can also use the MS Crypto API, look up the documentation for CryptCreateHash in Platform SDK.

I want to be able to show a small dialog box displaying progress while a pre-existing thread does work. I think the UI-threads are the right solution to my problem. I found this page and it looks like just what I need. I don't see how to show a dialog box in the process, only how to utilize CWinThread as a user-interface thread.
|

You can start the UI thread. Then display a modeless dialog box from within the thread, and close the modeless dialog box when you are done and about to exit the thread.
I usually have the primary UI thread create the modelss dialog box, then let a worker thread do a job and post messages to the HWND of the modeless dialog box regarding status, then when the worker thread is done, it signals the main UI thread which can remove the modeless dialog box.
You can use RegisterWindowMessage to set up custom messages to communicate from the worker thread to the mdoelss dialog and the main UI thread.

Thank you for the reply, it's very informative. I looked into a modeless dialog because I doubted I could interface with a modal dialog box. I found the function CreateIndirect(...) but I couldn't close the deal on the arguments so I abandoned it in favor of trying another route which I am not optimistic. I already have a series of handles setup to provide synchronization and I can wait for each event and adjust the dialog appropriately.
Can you give me a more detailed sequence of events, possibly with function names and such. I'm having a hard time filling out my CWinThread-derived class, I can't quite define in my mind what should be in my main controlling function and what should be in the UI thread.

I have tried Platform SDk, I download the SDK from MS-Website, and installed it. But i found the Platform SDK seem not well! My question are:
1) Some Windows DataType are not declared! for examples:
DWORD_PTR, PDWORD_PTR, ULONGLONG...
I check the SDK Document, Say these data type declared in BaseTsd.h! But
I opened headfile, I did not found these data type declare. Whats wrong?
2) After install Platform SDK, int the c:\C:\Program Files\Microsoft
Platform SDK\ folder, there are many head file'name and system files'name
are same as in the folder : C:\Program Files\Microsoft Visual Studio\VC98
So which file I will be useing in my projects? And how do I use the
different fiels?

You can configure the Visual Studio default directories to search the newer platform SDK header files and libraries. The ones shippd with Visual Studio are just 'older' versions of many of these same files.
See Tools|Options|Directories... menu item in Visual Studio 6.0 IDE to make changes. Make it search the Platform SDK folders ahead of the older ones that came with VS 6.0.
