I am trying to automatically extract all time stamps in a pdf file. These are typically in a line like:
when="2010-07-30T15:20:30+04:00"
For this I was thinking of using CStdioFile and the ReadString function. Somehow this doesn't work. My example code is below. Is this because pdf is not a true text file, because strings read can be longer than some max,...? Any quick way of reading the file and extracting the desired text between the brackets?
Code:
CStdioFile InputFile;
if (InputFile.Open(FileName,CFile::modeRead)) {
does a pointer keep track of time stamps when it is created? i am trying to use it to create a table that can store the access count and the temporal locality at the same time.
so i have a loop that will run x number of times and each time it will produce a prize which is a certain sum of money. I need to a way to sum all the money earned. I am thinking there should be a way to extract the prize one for each time the loop runs but i am not sure how to do that.
I got as far as getting a web page into an IHTMLDocument2 but I don't know what to do from there, all the examples I found are C# or .NET or something else I don't understand.
Any simple example in C++ of getting all the links from an IHTMLDocument2 ?
I was able to do this:
Code: IHTMLElementCollection* collection; hResult=document->get_links(&collection); long nLinks; collection->get_length(&nLinks); // returns correct number collection->Release();
How do I loop through the collection and extract the actual links ? Also, if they come out as BSTR do I simple treat them as WCHAR* ? If I can do that I can figure out the rest myself.
I am writing a program to play rock paper scissors, and I am trying to get a vector to store the result of a given round of play, and output it as a declaration as to who won. I can't figure out how to store the values in the vector properly, and how to use the vector as an argument to output the result of play.
I need using CSemaphore class in MFC C++ application. I have an edit1 box with multil ine and each line has a string. I'm trying to loop through edit1 box and for each string to start a thread that is using the string for specific function. I'm trying to limit the run of only one thread at the same time with semaphores but all treads start at the same time.
So when i click button1 i loop through edit1 box and start threads:
Code: void CMFCApplication1Dlg::onButton1Click() { int i, nLineCount = edit1.GetLineCount(); CString strText, strLine, mesaj; for (i = 0; i < nLineCount; i++) {
[Code] ....
While looping through edit1 box multi line and starting the threads:
Code: UINT CMFCApplication1Dlg::StartThread(LPVOID param) { WaitForSingleObject(semafor, INFINITE); // wait for semafor to signal THREADSTRUCT* ts = (THREADSTRUCT*)param; // here i'm doing some operations with the string from edit1 box ReleaseSemaphore(semafor, 1, NULL); //release the semaphore for next thread to begin }
Instead of running only one thread at a time all threads start. What am i doing wrong ?
We have an assignment to produce code to gather a string of input from the user in which they are entering a date. We then have to extract parts of that string to make substrings, and display different formats for the date(I will add my code in here so you can see what I have done). It took me a long while plucking away at this to understand this part. You will see that at the end of my code I have opened a file months.txt. We were provided with a file which states months corresponding to dates. I.e. 01January 02February 03March 04April, and so on until December. Exactly how I have typed it is how it is in the file.
I understand how to open and extract what is in the file as a string. I have extracted this as a string called myMonth (as you can see in the code as well) NOW,
I am supposed to have the program search for the month in the file, matching that to the month the user has input earlier, and then use the number infront of that month. I understand the basics of using find(), and making substrings. But how on earth do you get the computer to correlate what the user has input for a month, to finding that in the file, and then using the correct number.
Here is the code I have done so far:
#include <iostream> #include <fstream> #include <string> using namespace std; int main() { string myDate; // Date input from user; string myMonth; // Input from months.txt
I have been given a task to debug a C++ project. I have not written a single line of code in this project!!
This project executes for about 5 minutes without problem. Then it ends with an exception "Unhandled exception at (some .dll name) in EITos.exe: 0xC0000005: Access violation reading location "
Now every time I execute the program. The error is from a different dll. Sometimes it is a dll created by other programmers, sometimes it is related to QT. So I don't think this is a code problem. Is there any project setting that would affect this?
This program is suppose to store input from a user (example 14 15 27) and output it three times. Once to confirm the input using the get function to recall the data, once to look like military time (14:15:27), and once to look like slandered time (2:15:27 p.m.).
The program runs, but this is what I'm getting:
I'm thinking its because I'm using the same integers to store two sets of data. I tried to create different integers for every set of data it didn't seem to fix the problem. The fact that the program is running makes trying to figure out where the problem quite confusing to say the least.
Code: #include <iostream> using namespace std; class time { private: int hr, min, sec;
I want to extract polynomial coefficient out of a string recieved by input, for example if i enter 4x^3+2x^4+3 , the resulting out put be : 2 , 4 , 0 , 0 , 3
Create a simple data file like the example shown below containing the 4 dates below plus 10 or more additional dates. The file should include 1 date per line and each date should have the form MonthNumber-DayOfTheMonth-Last2DigitsOfTheYear with no extra spaces. All dates should be in this century. No error checking for invalid dates is necessary.
My Output displays like
February -19,1991
How do I get my program to ignore the dash between the dates?
#include <fstream> #include <iostream> #include <string> #include <cmath> using namespace std; int main(){ const int M = 13;
Im working on my project for college and i want to know how to add sth similar to a chronometer for user to see how much time have passed while entering some characters using cin.getline function.
Any application or open source software (vc++ or vb.net or c#.net) that can display a high resolution map and i can input real time latitude and longitude of points through an external file and those points can be displayed on map in real time..... I am all new to this plotting on map stuff....
I was assigned a project to implement a real time graph to an application which continuously outputs data numerically through the GUI. The application that was created to do this is written in C.
I have to turn those numerical numbers into a graphical display that is periodically updated to appear as real time.
My adviser suggested using NTgraph [URL] ...... I had no clue how to implement this to my code and was finally able to understand that the .OCX needs to be registered as a COM and then imported to the application using visual studios. However, I get an error when I try importing it since it is in C (Visual Studios 8) and not an MFC application.
So my question is if it would be possible to implement the ActiveX control to my application even though it is not an MFC application and how to go about it.
So this may be against the rules, not sure, grey area probably? However I just bought the PC game Oil Rush, and was having a look at how the assets are packed. As with most games the textures, scripts, sounds and audio are all free to access.
However the game data such as maps, models and other, are packed into UNG files, i.e a custom encrypted file format, which probably is also compressed. So I googled for an unpacker/extracter and found one which also comes with the C source. You can download here. [URL] ....
So I am trying to figure out how these authors work out this file format, from the source we have,
If I have a number 117, represented in binary as : 01110101 and I wanted to grab the top nibble. What would be the decimal value I would be extracting?
Would it be 0111 or 0101 decimal values 112 or 5 or is my understanding completely wrong?
Processing time for the above code takes 9500 to 9900 microseconds (Used QueryPerformanceCounter).
Code: TempArr[0] = ((BYTE*) pvData) [0];
This code takes 1100 to 1200 microseconds. My doubt is, The processing time of PVOID data into byte array conversion takes time like above? Or any other easy way(PVOID data into byte array conversion) to reduce the processing time?
