We are in process to get rid off Roguewave library while moving from AIX to Red hat Linux.
Need to replace RWZone, RWTime stuff with standard gnu implementation on RHL.
void readpatient() {
int count = 0;
f = fopen("patient.txt","r");
while(!feof(f)) {
printf("
%d",count++);
p2=new patient();
[Code] .....
Here is what I've tried. I'm trying to read a file aND print stuff in it, but my while loop isn't ending up.. What should i do? It only prints patient name 1 time and after that it prints nothing.
removing system("pause");
results in an endless loop.
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.
Using cin.sync() works great so far, but my program still breaks if you copy something with multiple lines into the console.
string test = "";
while(true) {
cin.sync();
getline(cin, test );
cout << endl << "test: " << test << endl;
}
However, if you were to copy this:
1
2
3
and paste it into the program, the output would be1
2
3
test: 1
test: 2
And if you press enter one more time:1
2
3
test: 1
test: 2
test: 3
The 3 finally pops out.
Basically, the task is to replace tabs with spaces, ensuring that the number of spaces is appropriate to get you to the next tab stop (i.e. if you were only 4 spaces away from a tab stop, don't replace the tab with 8 spaces).i've seen have included character arrays, and many have included multiple functions. I realize the text says "these exercises suggest programs of somewhat greater complexity than the ones earlie in this chapter," but it seemed like a very straightfortward task.Have i oversimplified or something?
Code:
#include <stdio.h>
#define TAB_STOP 8
int main()
{
int c, i;
}

I am new to C, but I recently completed an exercise from a book that finds a string in another string, removes the string, and replaces it with another string.

// Replace String
#include <stdio.h>

bool replaceString (char source[], char s1[], char s2[])
}

i want to replace tabs with spaces but i didn't get it. I also tried to count all the chars that i read from a file but that does also not work.

int char_ = 0;

i`m currently racking my brains out over this issue. How do i go about the x as the first occurrence of the letter?
lets say helxo , x is the 2nd occurrence of l. I will want to change back x into l
i have replaced it with x in the earlier step with this code...
string everySecondChar(const string &s,char source,char distance)
{
string t(s);
for(std::string::size_type even =0,pos=t.find(source,0);pos!=std::string::npos;pos=t.find(source,++pos))
{
[Code]....
i would like to reverse the process now, letting x becoming l again!
Is there a way to replace 3 char's in a string. For example i have a string containing
s = "The school is called 7x8"
I want to replace the "7x8" with "LSU". But the "x" can be any letter or number.
Is there a way to do that ?
Supposed i have a word hammer.
how am i suppose to search for the 2nd occurrence of the letter and then replace it with x?
example hammer will become hamxer
I thought about using replace for it, however i`m lost on how to find 2 occurrences of the same letter in the word.

View 5 Replies View RelatedI have a datagridview (dgv) that is bound to database:
QtyOnHand QtyOnHold QtySold QtyAvailable
10 2 1 null
12 null null null
null null null null
7 5 null null
25 null 5 null
I want to iterate through the datagridview and calculate the last column with this formula:
QtyAvailable = QtyOnHand - QtyOnHold - QtySold
so the datagridview should become:
QtyOnHand QtyOnHold QtySold QtyAvailable
10 2 1 7
12 null null 12
null null null null
7 5 null 2
25 null 5 20
I use this code:
foreach (DataGridViewRow row in dgv.Rows){
if (string.IsNullOrEmpty(row.Cells["QtyOnHand"].Value.ToString())){
row.Cells["QtyAvailable"].Value =
Convert.ToInt32(row.Cells["QtyOnHand"].Value) -
Convert.ToInt32(row.Cells["QtyOnHold"].Value) -
Convert.ToInt32(row.Cells["QtySold"].Value) -
Convert.ToInt32(row.Cells["QtyAvailable"].Value);
}
}
The problem is when any of the value on the right side of the equation is null, the whole equation is invalid. I need to replace the null values by 0 on the fly so that it can be calculated. Note that I do not want to actually replace the null values in the second and third columns of the table, just replace it in the equation whenever it applies to make the calculation work.
I've been trying to calculate the Second standard deviation but the average in the second loop isn't calculating correctly which is causing the standard deviation (method 2) to not calculate correctly. I can't find anything wrong.
Code:
#include <iostream>#include <iomanip>
#include <string>
#include <fstream>
#include <cmath>
usingnamespacestd;
int main ()

I have a program that will calculate max, average, etc from a file of numbers. However, I cannot get it to calculate standard deviation.

I'm having a bit of problem. I've set the string 'Absent' to all student in a file. However, I want to replace 'Absent' with 'present' when the correct ID assigned to a student is entered. In other words, 'Absent' will only change to 'Present' for a specific person at a time. I'm not sure how to implement this
View 4 Replies View RelatedI'm learning internet sockets right now and to that end I've made a simple client/server chat program centered around select(). I've got it to where multiple messages can be sent and received on either side and the "prompt" will move down 1 line each time accordingly.
My only sticking point is when someone is in the middle of typing a message and a new message is received. The message they are currently typing is going to be deleted, so they'll have to start over again. What I want to do is grab the current contents of the stdin buffer (meaning, there's no ), save it, print the received message and move the prompt downward as usual, and then put that saved message back into the buffer, meaning not only is it back on the screen now, it's erasable too as if nothing ever happened.
I know that this will definitely be some very very non-standard C, and that's fine. To that end, I've read that curses, GNU readline, and termios are possibilities for this. I've tried those, but am having trouble making it work.
This will be a moot point when I put a GUI on it soon (probably wx, but maybe Qt) since it won't even be an issue, but I'm determined to make this work. Both systems (the "client" and the "server") are Linux, one being Ubuntu and one being Debian.
I have a text file, like that:
(A1*
*
*
*A1)
*
(AM-MNR*AM-MNR)
(V*V)
(C-A1*
*
*
*
C-A1)
Now, I would like to replace some elements, follow the rule:
-(A1* ---> B- A1
- characters "*" following is replace by I-A1
- *A1) ---> I- A1
The output like that:
B- A1
I- A1
I- A1
I- A1
*
B-AM-MNR
(V*V)
B-C-A1
I-C-A1
I-C-A1
I-C-A1
I-C-A1
How can I do now?
My text file have 220 663 lines and 858 995 characters (I used Linux commands : wc to count them. If I use array to store data, I think it's too large array. But if use fstream, I dont know to access each element in stream to compare and replace. I dont know How many labels such as: A1, C- A1, AM- MNR... which I have to replace.
I adapted the code from the following: [URL]
To replace a string in my file with another. The file contents look like the following:
abc 123 0
"abc"= The username
"123"= Their password
"0"= The amount in their bank
I want to change their bank amount.
But, it isn't working, nor is it even giving me an error code.
// When the user logs out, make changes to their bank
string strNew = std::to_string(player.bank); // String representation of the revised player bank
ifstream filein("user_accounts.txt"); // Old repository of player data
ofstream fileout("user_accounts_new"); // New repository of player data

Method which i use to Webrequest requests doing the job well but very slow i need to wait on every foreach item finish a lot of time. I run Execute method inside foreach statement unfortunately it takes a lot of time. I would like to convert it to asynchronous.
//this is in foreach statment and call for every request
public static void Execute(string xmlFileRequest, string xmlFileResult, string InventoryElement, string TimeOutFile, Server server)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(server.ServerIP);
request.Headers.Add(@"SOAP:Action");
request.ContentType = "text/xml;charset="utf-8"";
[Code] ....
Unfortunately i got error (Webrequest timed out)on that line:
using (Stream stream = request.GetRequestStream()) {
soapEnvelopeXml.Save(stream);
}
This is strange because i know for some elements i am expecting timeouts and i am getting them - but if they are then the line which is occuring should be: (this is without my tries) and that should be :
using (WebResponse response = request.GetResponse())
Then I am saving that element to
`sw.WriteLine(InventoryElement);` inside catch.
So the code is working ok in case my code before tries.
