Visual C++ :: PrintDlg With Special Page Range
Mar 24, 2014
In my app the user can select the pages to print by typing in a start and an end page. I think this is the standard dialog.
How can I give the user the possibility to select e.g. page "1,2,6-9" like in Word?

I have a file that contain different content, some lines inside that file looks like that :
Time : xx:xx:xx
Time : xx:xx:xx
So, I want to grab lines that start with "Time : " and put them inside a list<string> for later use. I am using windows so I don't know if the newline character is '
' or '
' also I don't want my grabed line contain any special character.
I have this code, but didn't work well because some special characters remain inside the string.
Code:
string buf;
list<string> ls;
ifstream read("test.txt", ios_base::binary);
while(!read.eof())
{
getline(read,buf,'

I created a MFC dialog using CDHtmlDialog and added a HTML page with many controls and one of them is a IMAGE tag. I got a default image loaded from the hard drive displayed in the HTML page. Up to this part, everything works fine.
Now what i want to do is, dynamically change the image based on the user click on one of the HTML buttons. I don't want this image source to be hard coded in the HTML nor the image source send from the MFC app.
What i want is for the MFC app to send the image data to the HTML in some (binary) format and then the page to display the image.
The possible option i was thinking of was to read the image file which is already in my hard drive as a binary file and send the binary data across to the HTML as a memory buffer, and then use JavaScript to decrypt this binary data and display the image.
Basically what i want is for the HTML page to display a image from the memory. how to do this?

I am writing an MFC app in Visual Studio 2012 that will open a JPG file as binary and read all the contents to a CString.
I am able to read it to a std::Vector, but that doesn't work much as i need to pass all the binary content as a MFC CString to another function.
More Update:
Let me explain the problem a little more deeper.
I am trying to call a JavaScript (JS) function in a HTML page and then want to pass the binary date. The C++ function that calls the JS is given below.
bool CallJavaScript(const CString strFunc,CComVariant* pVarResult);
The 1st argument is the JS Function Name and 2nd is the one to pass the Binary Data. 1st argument works fine as i am able to call the JS fucntion called "LoadImage" without any problem. Problem is with 2nd argument that's supposed to take the Binary data of the JPG file.
If i try to pass a std::Vector or std::string then it will give me an error.
But it's happy if i pass CString. But then with CString there's a problem with NULL characters.
Actually my plan is to pass the binary of a JPG to a JS function and let it display the JPG in the HTML page.
Can i typecast a Vector or std::string to a CComVariant*?

I'm making a small MFC module that should generate a report (formatted using HTML) and then display it for a user on schedule at 8:30 AM every day. Pretty straightforward stuff.
I compose my report and then save it as a local HTML file in the CSIDL_APPDATA folder. I then use the following calls to display it using the default web browser (Internet Explorer in this case):
Code:
//Error checks are omitted for brevity
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE);
ShellExecute(NULL, NULL, strSaveFileTo, NULL, NULL, SW_SHOWNORMAL);
This module is run on schedule from the Task Scheduler. (The task is set up to run when a user is logged on, which is all the time for that PC. It is never turned off, put to sleep, etc. That computer has only one user that is never logged off either.)
This works perfectly fine when I test it by setting the task a minute or so in the future. But when the actual task is supposed to run at 8:30 AM, when the user wakes the screen all they see is a blank Internet Explorer page. (Note that if someone refreshes that page by hitting F5, only then my report is shown on the screen.)
So I started looking into it:
1) I checked that the file is properly saved (before calling ShellExecute) by reading it back and by comparing it with the original HTML markup that I saved earlier. It's all correct there.
2) I then checked the power saving options. That computer is set up to show screensaver after 5 minutes and to turn off screen after 25 minutes.
3) The web browser that causes this issue is IE version 11, with the latest updates installed. The operating system is Windows 7 Professional.
And why is IE showing a blank page only when computer is running unattended?

So there is suppose to be a constant that shows the total number of values to be shown in this range. The user enters two values, lets say userMin is -2 and userMax is 2, it's suppose to add 0.2 to -2 and so on until it reaches 2. It starts doing that up until it reaches -1.0, then it goes to -0.9, -0.7.... etc, It also goes beyond 2.
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
cout << fixed << setprecision(1);
float userMin;
float userMax;

I'm having problems with progress bar when using a big number in set range. For numbers below 50000 it works very well but for big numbers like 100.000 it doesn't work, it makes 2-3 rounds of animation
Code:
int number= 50000; // 50k works well but if i put 100k it won't work (it will animate 2-3 rounds instead of complete one)
progressbar1.SetRange(0, number);
progressbar1.SetStep(1);
for (int i = 0; i < number; ++i) {
listcontrol1.InsertItem(i, _T("whatever"));
progressbar1.StepIt();
}
What's wrong with the code ?

Using Excel Automation in Visual Studio 2010 C++, how do I define a name? As a user of Excel, you can enter a name that then can be used in formulas to refer to a range of cells. The range changes as the user inserts columns or rows. My program has worked with various versions of Excel dating back to the early 2000's.
I have a bunch of classes derived from COleDispatchDriver: CXLApplication, CXLRange, CXLWorkbook, CXLWorkbooks, and CXLWorksheet that have many functions, but I have no documentation... How to define a named range using functions of these classes (probably CXLRange)?

Write a function named generateLotteryNumbers. The function is passed an int array of size 5. The function should generate 5 different lottery numbers in the range 1 to 50 inclusive and place the numbers in the array. The declaration is as follows:
void generateLotteryNumbers (int lotteryNumbers []);
Note that no data is passed in to the function. The array is used to return the function results. Thus the parameter is an OUT parameter. Do not display the result. Return the result.
Do not seed the random number generator inside the function. If you seed the random number generator inside the function and the function is called many times in the same second, your function will return the same results each time it is called.
I know how to generate the numbers in the specified range but I do not know how to test for duplicates. Here is the code I have so far:
Code:
//This program will test the "generateLotteryNumbers" function
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
void generateLotteryNumbers (int lotteryNumbers[]);
[Code] ....
When I try to compile this, my compiler tells me that lines 41 and 46 require an array or pointer type.

I have a ULONGLONG variable uDate which express the number of dates starting from 0001-01-01, up to 9999-12-31. Now I want to convert it into a string like this
"yyyy-mm-dd"
However, the COleDateTime can only express the date from 100 to 9999, smaller than what I need. So are there any third-party classes or libraries that can express this. Or make the conversion from uDate to CString?

I want to define a range of exit codes in my application. These codes will be used as a return value of ExitInstance function. I want to know the exit codes availables (values not used for example by windows to inform about an other error). When I force to crash my application, I get some different error codes: 8148, 10176.
What is the no available range exit codes?
Is this the ranges code unavailable?

There are many libraries in C++, but how are they made?
For example: SDL, SFML, Open CV, STK
There are no special functions in C++ from which we can create such libraries, If I wanted to create a library that processes sound signals, how would I do that? How can I access the mic, speakers and process the signals.
Open CV processes videos but which functions does it use?

I have an array in a class with some numbers in a specific order. Now I want to create a set with references to that array ordered after the arrays content. I thought a solution could be something like
class Holder {
int o[10]= {1,5,7,2,3,8,4,9,6,0};
public:
set<int,my_order> m_s;
Holder() {
for(int i=0; i<10;i++) {
m_s.insert(i);

How to create the my_order.

how to rearrange lists in an special manner.
I have heard about the hashset but I do not fully understand how that thing works or if it is the best option for this issue.
Basically I have 3 lists: LIST1, LIST2 and LIST3.
LIST1 is a set of xyz points and LIST2 shows how the points are connected (clockwise, counter clockwise, coolinear).
For example the fact that in the first line of LIST2 appears 0, 1, 2,-1 means that the points in LIST1 are connected as follows:
(0 0 128.588459085565)->(25 0 134.979628462965)->(0 0 134.979628462965)
Same for line2 of LIST2: 1, 4, 2,-1
(25 0 134.979628462965)->(25 0 140.100717207301)->(0 0 134.979628462965)
etc...
The value -1 at the end of each line does not mean anything but I need to keep it.
Finally LIST3 tells me if the points are connected counterclockwise (-1), clockwise (1), or coolinear (0).
The thing is that I want to get things as follows:
If the values of list 3=1 then I need to extract all the points in the list 1 that correspond to the value 1 in order. However the values in LIST2 cannot keep being 1, 4, 2,-1 they need to be reorganised starting by zero. Expected result in LIST2= 0,3,1,-1.
We need to do this for each value in list3 (1,-1 and 0).
The idea is to get 3 groups of values:
- Group 1 including all the values that are clockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.
- Group 2 including all the values that are counterclockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.
- Group 3 including all the values that are coolinear (list3) with the points in order in list1 and showing connections starting from zero on in list2.
The idea is to be able to print 3 files in the following way:
FILE1:
Points which are clockwise in LIST 1
...
Connections of those points in LIST 2
...
FILE2:
Points which are counterclockwise in LIST 1

Code:
Exercise. 1.5 A number is special if it is divisible (no remainder) by 15. A number is big if it is greater than 999. A number is weird if it is divisible by 5 and 6 but not 18. A number is scary if it is big or weird.
Write a program to check which of the following, 450, 540, 600, and 675 are special but not scary.
