From MSDN:
double modf(
double x,
double *intptr
);
Splits a floating-point value into fractional and integer parts.
This function returns the signed fractional portion of x. There is no error return.
x : Floating-point value.
intptr : Pointer to stored integer portion.
The modf function breaks down the floating-point value x into fractional and integer parts, each of which has the same sign as x. The signed fractional portion of x is returned. The integer portion is stored as a floating-point value at intptr.

Hi
I am trying to develop a new CButton sub-class that has the following behaviour:
- when the user clicks and holds the button, and event is fired
- when the user releases the button, another, different event fires.
In other words, I want to know when they press (and hold) the button and I want to know when they release the button.
With CButton, I only get 1 event: a WM_COMMAND when the button is released.
Any help would be appreciated. Thanks.
Tim

The latter is an API, while the former is a class that encapsulates this API.

Hello All,
I have been working on a DLL (Regular DLL with MFC statically linked) that contains a CDialog that I would like to run as modeless. In order to reset the CWinApp's ref to the Dialog to NULL when the Dialog closes, I am trying to store a pointer to the CWinApp so that I can m_pApp->setMyDlgNull(). It seems as if this should work, but whenever I try to add the pointer into my CDialog class, the compiler acts like it does not know what my CDLLApp is. I am not sure what is going on as I have #included my CWinApp's header and I can get the popup with my setMyDlgNull() function when using CDLLApp:: (does not happen when i do not #include).
I am sure that I have made the most idiotic mistake so go easy on me

Can anyone tell me if MSDN .NET 2003 is available for download? I remember a 4 Gbyte DVD version was available a few months back, but I was hoping that I could get something that I can put on normal CDs because I do not have a DVD in my computer. I ran a few searches online but I cannot find anything. I am just wondering if it is available at all?

Thank you for the ingenious idea. Have you applied for the Nobel Prize recently in the area of critical thinking? If you haven’t please don’t let you ingenuity go to such a waste.

He's right. It's only available for download to MSDN subscribers...

Thank you very much Ryan. That's an answer that I understand.
About the anonymous reply: He didn't really answer my question. I didn't ask for the nearest store. I asked whether I could download it. I already have it on a DVD and I can get the CDs for $3 here at the place where I work but it would take them several days to deliver the CDs to me. I need it today but it is clear that that's not going to happen .
Once again thank you.

Agreed, but (no offence intended) you could possibly have phrased your answer a little more politely

sorry about the formatting - i don't know how to make a table.
take these numbers...
Cost; Age; Cost * Age
x; 6;
8,025; 20; 160,500
346,950; 47; 16,306,650
279,252; 58; 16,196,616
387,640; 69.2; 26,824,688
84,500; 80; 6,760,000
Totals
1,106,367; 59.9; 66,248,454
the task is to find x which brings the total Age (59.9) down to 40. now, the total cost number (1,106,367) can not change. meaning, x must be subtracted out starting from the bottom. so, if x is 80,000, 84,500 is reduced to 4,500 and Cost * Age becomes 360,000. the idea is bring total Cost * Age down to 44,254,680 (1,106,467 * 40).
i just can not for the life of me figure out how to calculate x. can anyone help?
thanks.

How is the age total 59.9 when you have 6 + 20 + 27 + 58 + ...
How can you choose x to be anything but 0 if you want to total cost to remain the same?
I don't think your problem is well defined.

godzooky, the problem is a bit complicated. It is one of those problems that are studied in game theory and linear programming. I tried to solve it but my current mathematical skills leave much to be desired for. I have a minor in it but I can barely remember to solve a second degree equation and let alone a system of equations with a lot of restrictions. By increasing and decreasing the costs you decrease and increase the rate of the function Cost*Age. You have to find a point in where the rate you increase X and the rate where you decrease the other costs have to satisfy the condition that SUM OF ALL (Cost*Age) ~ 44,000,000.
Let me give you something to start with and you might try to get a feasible solution from there. Lets call Cost Ci where i = 0 to 5 and where Ci = x, C2 = 8,025 and so on. Ai is the Age and Ci*Ai = Cost*Age.
The initial equation is:
C0*A0 + C1*A1 + …+C5*A5 = 66,248,454. C0 is X and it’s initially 0 so this becomes:
A0 + C1*A1 + …+C5*A5 = 66,248,454
Ai doesn’t change, only Ci does and lets call Di the amount that we will increment and decrement Ci.
(C0+D1+D2+..D5)*A0 + (C1-D1)*A1+…+(C5-D5)*A5= 44,254,680.
Don’t forget that since C0 = X which is 0 initially then D1+D2+…+D5 becomes your answer. Now you have to write some code which will assign values to Di until the equation is satisfied. At first I would recommend that you decrease those costs where the age is the highest because there the rate of the increase is higher and then slowly proceed with the other costs where the age is lower.
Sorry, but this is the only help that I can provide at the moment.

Friends,
I want to programatically launch MS-Word document say like c:\\MyFolder\\MyFile.doc. I am trying CreateProcess() but it is not working for me. I think i am doing something wrong while giving first and second parameters of this function. On client machine the word document can be present at any location of the drive and MS Word can be installed in any location.
Plese tell me how to launch MS Word document when we know its fully qualified name. I dont want to use Automation

I use this:
{
SHELLEXECUTEINFO ShExecInfo;
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = NULL;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = 0;
ShExecInfo.lpFile = DocName;
ShExecInfo.lpParameters = NULL;
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_MAXIMIZE;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
}
Just put your document's name in DocName and the system will find the program that handles the document. I have used it with a .rtf document and it loads MSWord on systems that have MSWord or it loads WordPad on the systems that don't have MSWord.

Hi All,
Is there way in which i could monitor the controls in Webpage(IE) using hooks in VC++. (say, the userid or password edit box in yahoo)
I have tried invain to get any handle to these 'inner' windows inside the internet explorer.
awaiting your suggestion/hints.
regards
Ramesh

The controls that appear in a webpage aren't anything like the standard controls you see elsewhere in Windows. IE has its own APIs for accessing them.

No need to use Hook, When MS Provide you direct access to IE using BHO, here is link for that!
