C Sharp :: Displaying Text File Block By Block In C#
Dec 21, 2012I have a text file that is divided into blocks:
#1
1:animal
2:food
3:moves
4:oxygen
#2
1:eats:2
2:breaths:2
3:can:1
4:is a:1
#3
1:1:2
1:3:3
1:2:4
And the following program that displays block by block:
StreamReader streamReader = new StreamReader("G:LAB123LABWORK2.txt");
int block = 0;
while (!streamReader.EndOfStream) {
string line = streamReader.ReadLine().Trim();
if (line.CompareTo("") == 0)
[Code] .....
My problem is am supposed to add a verification code so that if i put a string e.g 1:?:? it returns the block where the string is found and gives of all possible answers.
Attached Files : LABWORK2.txt (240 Bytes)

C Sharp :: SQL Server Connection String To Connect Through Domain Name (internet)
Sep 20, 2012I have tried to connect my sql server 2005 using a domain name. i have bought a domain name and a dns client. this is my connection string
{ SqlConnection sqlconn =
new SqlConnection("user id=user1;" + "password=pass2;"
+ "server=www.mysite.infoServerInstance;"
+ "trusted_Connection=false;" + "network
library=DBMSSOCN;" + "Integrated security=false;"
+ "initial catalog=Mydatabase;" +"connection timeout=5
;"); }
I have added sql browser & sql server in fire wall, and also enabled tcp port 1433 and udp port 1434. the above connection string works perfect when i run it in the server machine, but whenIi try to run it on other machines I am getting an error that server is not available or cannot find the specified server.. I desperately need to access my database through an url. ie., through internet..
Visual C++ :: Internet Explorer Displays Blank Page When Opening Local File While Screen Is Off?
Apr 28, 2015I'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?
C++ :: Access Private Data Of Base Class Without Access Modifier
Sep 9, 2013if we don't provide the acces modifiers for base class and we need to manipulate the private data of base class in derived class. Is there anyway to acces the private data members? Here's a coding example
class A {
private :
int a;
};
class B : public class A {
public :
void displayA() { cout<<a<<endl; }
};
how i can acces the a of base class A in derived class B without acces modifiers.

C :: Clrscr Function In Code Block
May 1, 2014I start working on CodeBlocks and stuck in a situation. The situation is that I want to clear my output screen every time the main function calls some other functions. To do that I use clrscr() function but its not working. After spending some times on web, I found that its a non-standard function so this extension is not used by the new compiler's. Another thing I find to use < cstdlib > library. But unfortunately it do works only for C. It works for C++.

Dec 7, 2011I have a program that I can only run one instance of. When I try to start it a second time, it doesn't do anything. I would like to create a script that loads the program in a way that I can run multiple instances. Since I assume the program checks the process tree on startup to see if an other instance is already running, I figure disabling access to the process tree could do the trick.

C++ :: Implementing Signature Block Class

C++ :: Control Execution Of Code Block By Entry
Apr 25, 2013I have a program including several code blocks in the following simplified structure:
int main() {
// block A
if(a > 0) {
}
// block B
if(a > 1) {
} }
Block A and B should be executed separately, according to entry from keyboard. For example, if entry "1", block A will be executed and block B will be ignored; if entry "2" the inverse will happen.
I can control the execution of these two blocks through macro but the code will be separated during compilation. But is there a way to control them without using macro?
C++ :: How To Skip A Block Of Commands When User Interrupts
Nov 3, 2014I am working on a program that does something like this,
Void main() {
cout<<"H";timedelay(1);
cout<<"E";timedelay(1);
cout<<"L";timedelay(1);
cout<<"L";timedelay(1);
cout<<"O";timedelay(1); //timedelay(int a) is a function which gives a delay of 'a' seconds.
{
....
}
}
This code is just for fancy and I would like to squish in some statements which would give the user an option to skip it (by entering any keyboard key),and resume with the rest of the program.
C/C++ :: Boost Dynamic Bitset Block Size
Mar 12, 2012I am designing an application in which I need to deal with many different variables in which different sequences of bits are stored. I have very strict memory requirements so I decided to use the boost::dynamic_bitset data type which works very well in my scenario as I need to dynamically allocate/deallocate/resize the variables.
The only problem is that I am not able to change the size of the blocks in which the dynamic_bitsets are stored.
I mean, even if I specify the blocks should be "unsigned char", I always obtain 32 bytes allocation by sizeof function, even if the variable is empty.

C++ :: Point / Line And Block - How To Design Data Structure
Mar 27, 2014Suppose, I have point_c, line_c and block_c three classes:
class point_c {
public:
double x, y;
};
class line_c {
public:
vector<point_c> Pt;
[Code] ....
As you can see, lines are composed of many points, and blocks are composed of lines and points. And I defined some member functions, so that I can add points or lines as required by line and block.
But, here comes the problem, if I use line.insertPoints(), or block.insertPoints(), the points will be stored in line or block. That is not what I want.
I want have a single place to store all points, a single place to store all lines, and a single place to store all blocks.
Then I guess I need some global variables
vector<point_c> Pt;
vector<line_c> Ln;
vector<block_c> Bk;
And I should change the classes into:
class point_c {
public:
double x, y;
};
class line_c {
public:
vector<size_t> PtIndex;
[Code] .....
in this way, the member functions will create the real entities into the global vector and set an index pointing to that entity. But this approach just make me feel it is not OOP anymore. when people using these classes, they got be careful about the global variables.
