is there any sample that i can refer to in learning or as an example?
any suggestion?
can u pls explain in brief what this directX can do? as i know this is for gaming purpose. but i dun know how true it was.

Why My Programm is getting out when i try to place Rich Edit2.0 on my Dialog Panel??? Just when i get Rich Edit 2.0 out of my Dialog panel my programm works properly.

You need to call
AfxInitRichEdit();
I usually add it into the InitInstance function.

Can I control the Volume and Microphone of a USB Device from my application? Presently using MIXERCONTROL I am able to control both Volume and Microphone of the system from an application.
Is it possible to use this MIXERCONTROL it self or any other method?

Is there a simple way to hide the mouse on entering a window and show it on exiting it. I'm assuming there is a windows message that i need to handle, but I'm not sure which one.
[edit]ShowCursor does some of what I want, but I want the cursor to show in the menu-bar so I can click the minimize/maximize button[/edit]

You probably call ShowCursor in the main frame. Try to call it in the child window (or, generally, in the window, which occupy the client area of main window)

CFile::GetLength() and CFile::Seek() return a UINT in VC6 and a ULONGLONG in VC7. Is there a predefined macro that can be used to declare a variable in my source that will differentiate between the two. Right now I am using the following macro, but my code would be more portable if I used a predefined one.
#if _MFC_VER < 0x0700
# define SIZE_TYPE UINT
#else
# define SIZE_TYPE ULONGLONG
#endif

You could also just use ULONGLONG everywhere. Assigning UINT to ULONGLONG is fine by the language rules, because it's a widening conversion.

Im trying to run in debug mode an app that was converted by VS 2003
but in debug mode not compile, it say this error:
APP fatal error LNK1181: cannot open input file 'shlwapi.h' 
i add the include path where this file exist, but i get the same error
In release build works fine.

When the compiler starts acting "strange" it sometimes helps to exit VStudio and delete the *.ncb file in the same directory as the project. This file is some type of cache of information and it can get "stranged".

hi
i am having a problem with an infinite loop
can someone check out the code and tell me
what is wrong with it...
[code]
int main()
{
int numberOfResponses; //number of responses for candidates
int accumulator = 0; //adds up total number of votes
do
{
char* stateName = new char[30]; //char pointer array for stateName
char* dateOfPrimary = new char [30]; //char pointer array for date of primary
cin.getline(stateName,30) ;
cin.getline(dateOfPrimary,30);
cin >> numberOfCandidates;
primaries NewPrimary(stateName,dateOfPrimary);
cout << NewPrimary <<endl;
delete="" []="" statename;=""
delete="" dateofprimary;=""
for="" (int="" i="0;" <="numberOfCandidates;" i++)=""
{=""
char="" nameandspent[50];="" char="" array="" for="" name="" and="" money="" spent=""
cin.getline(nameandspent,50);=""
if="" (i="" !="0)"
candidates="" newcandidate(nameandspent);=""
cout="" <<="" newcandidate="" endl;=""
}=""
results="" newresults;=""
int="" votes;=""
cin="">> votes;
accumulator = accumulator + votes;
NewResults.voteArray[i-1] = votes;
}
NewResults.totalNumberOfVotes = accumulator;
NewResults.percentage();
cout << NewResults << endl;
cin >> numberOfResponses;
for (int i = 0; i <= numberOfResponses; i++)
{
int c, i, v;
cin >> c;
cin >> i;
cin >> v;
election MyElection(c,i,v);
}
char blank[5];
cin.getline(blank,5);
cin.getline(blank,5);
}while(!cin.eof());
return 0;
}
[end code]

Which version of VC++ are you using. I'm assuming VC6.
After a quick glance, I think your problem is
for (int i = 0; i <= numberOfResponses; i++) <br />
{ <br />
int c, i, v; <br />
cin >> c; <br />
cin >> i; <br />
cin >> v; <br />
election MyElection(c,i,v); <br />
}
You are redeclaring the variable i and then setting it to a different value. I think this may be throwing off your loop.
VS.NET wouldn't let the code compile, but VS6 would.

When you use iostream and some read function fails, a failbit is set to the input stream. Any subsequent readings will simply return without doing something. Hence you will never pass the eof of the input stream.
Because you declare a cycle iterator inside the cycle (as Michael P. Butler wrote), this cycle probably doesn't repeat numberOfResponses-times. And the subsequent read operations probably read different types, that they expect, so the read operation fail.
The solution is:
* check whether cin.fail()
* if yes, restore the failbit by cin.clear()

Can u make a graphic interface which interacts with some buttons ? .. for eksample if u have a dialog with some balls and a button, and when u press the button the balls start moving .. what should i look for? .. i tryed working with SDL but that dosent work for MFC or does it?
|
|

The interaction of a GUI, in it's simplest form, is implemented by a series of WM_PAINT calls.
You can, for example, create two integer variables xPos and yPos that determine the position of a ball when it is drawn on-screen. Then, a click of a button sends these balls into a continous WM_PAINT loop, and during each iteration of the loop, the positional variables are altered, thus causing the ball to "move".
This approach, however, will result in your application looking pretty much frozen, as it will stop answering to other messages during the animation loop. I suggest you dwelve into concepts like Direct3D and OpenGL if you want to draw fast graphics without obscuring the messaging queue.
Unfortunately I cannot provide you with a code example..

I'm not sure about SDL, but if you need a lot of control you can use DirectX. If all you need to do is use buttons and GUI components try RHW vertices and textured quads. It's a fair amount of work, but worth it once you've got it going. Some of the game programming sites www.gamedev.com and www.flipcode.com are good resources.

i wrote a program that monitors the printer. and save how many pages were printed.
but i have a problem. Word XP has a bug, when i print a multiple copies (more than one), by using GetJob function, i don't get the number of copies. the dmCopies value in DEVMODE struct, is 1.
i can't sell my program when this bug not solved!  ...
i thought about somehow to read the spooler file, but this is not generic...
somehow, Word XP sends the right number of copies to the printer, because the printer is printing the right number of copies.
but this info is not changed by Word XP in DEVMODE.
do you have any idea how to solve this?
please...
this is very important to me...
thank you very much.
|
|

|

Just a thought, but is Word maybe doing collation itself, by sending pages multiple times (instead of relying on the printer to collate)? Try printing with and without collation enabled in Word, and see if that has any effect...
---
the work, which will become a new genre unto itself, will be called...

my program use the FindNextPrinterNotification (i don't remember it exactly) to know when the user send something to the printer.
after that i'm waiting until it stop spooling and i pause the job and then i use GetJob() to get the information about this job.
there is the problem.
i don't get the correct number of copies if the program is Word XP. with all the other it's just fine.
i tried to change some of the Word XP options but nothing...
i think it's because Word XP don't use the generic Print Dialog like all other windows programs does.
if you have any idea...
i'm totally desperate.
please...
please...
thanks,

using Visual C++ 6.0 with MFC
I am using a RichEdit control as a simple editor.
I am not using word wrap so the lines extend beyond the width of the control.
Problem:
I often find that if I replace highlighted text or even just add text to an existing line the new text is not displayed. It appears to not repaint correctly. I need to insert a space at the beginning of the line, or otherwise make it move to get it to display the change.
Also often the scroll bars do not display even though the text is wider than the control. When the redisplay is corrected the scroll bars are also displayed.
Is there a simple solution to this?

Hi all,
I am building an application which has a log-in dialog. I need the menu and toolbar selections to be diabled in the beginning and i need them to be active only when a valid user logs in.
Can you please help me in achieving this?
