I don't know how to put this really, but I finished a program in Qt, and i want to know how to make a .exe file for it, so i dont have to open Qt and build the program every time i use it.
I have a batch of .pdf files (~1000) with names 001.pdf 002.pdf ...etc. Still pretty new to C, but would it be possible to write a program that would open a PDF, prompt a new name from user, and when entered, close the .pdf and open the next one in the list?
I am creating a console based application which needs to be dual tasking, which prompts me to share a single console for the GUI console based and inputs from the user.
I want to know if there is a mechanism through I can open more than one command prompt so that I would use efficiently both of them.
Furthermore, I would need also to know how to control on which to print and on which not to be printed.
Is there such a thing?
I am using Visual Studio 2012 Ultimate on a Windows 8.1 Professional PC.
I am fairly new to programming and I am writing a small POS system which in the background creates a receipt. I guess the relevant code would be this:
#include <stdio.h> int main() { FILE *receipt; receipt = fopen("receipt.txt", "w"); fprintf(receipt, "Coffee Bar
[Code] ....
Of course the last bit wont be running for you, since the variables are missing. My question now is, that I like to open this file in a text editor. The file should be opened with a command withing the code. Is that possible at all? As you might can tell the receipt should pop up after the program ran and the user should be able to print it afterwards.
I've almost finished a Terminal/Command Prompt Program that can do most of the things a Microsoft or Linux Terminal can do - but I have a problem. I've got it to open programs fine, and I can also open their browser to the download page if they don't have it, but I need my program to know if there isn't the software so a bit like command prompt where it says 'The system cannot find the file test.txt.' and then it'll take them to the website if they like.
My program closes after the out even though i've used cin.get():
I want the program to stay open at least until you press enter, even after the whole output.
Code: #include <iostream>#include <string> int main() { std::cout << "Please enter your name"; std::string name; std::cin>> name; // build the message that we intend to write
I'm using Visual Studio Express 2013 to create a Windows program that will upgrade my micro-controller firmware. I have a .exe program to upgrade it. What I normally do is I drag and drop a .txt file on the .exe program and it will be done. I want to write a program that will do the exact same thing. Where when I click on a button, it will run the .exe program with the .txt file.
What I got so far is just run the .exe program when i press the button. I do not know how to write a code to let the .exe start with the .txt file. Here's what I got so far.
Process.Start(@"C:UsersJayDocumentsVisual Studio 2013ProjectsWindowsFormsApplication1BSL_FilesBSL ScripterBSL_Scripter.exe");
That line only manage to open up my .exe file. How do I make it run with the .txt at this location?
Is there any way to read RAM memory directly. For say i want to access memory location 0x0100 to 0x120. How to do that. how to declare the variable, is it unsigned int. what is the type of read values it hex or ascii. how t cast it.
I'm successfully publishing an app to my website by publishing locally and then uploading the files but one of the options offered is to publish straight to the web site but I can't find anywhere to enter a user name and password for my web site. I could also do it with ftp but since the option is offered to publish directly to the web site I'd like to try that method. I'm using the Click Once method.
I wish to convert a character directly to a string for a top-secret project I'm working on. It needs to be portable across various machines with different sized Indians.
Code:
#include <stdio.h> int main(void) { const int i = 0x0041; const char *str_p = (char *) &i; }
[code]....
I want this to output an 'A', but I'm not sure this code will work on my friend's mom's S/360.
I've got two classes, which are both derived from the same two base classes. Here's a representation of the actual code:
Code: #include <vector> class BaseClassA { }; class BaseClassB { }; class TestClassX : public BaseClassA, public BaseClassB
[code].....
Basically, I'd like to know if it is possible to cast directly from a BaseClassA pointer to a BaseClassB pointer, without casting to the child class first.
I'm learning OpenGL using the C API and some of the functions' argument types have proven a bit challenging to me.
One example is the function Code: glShaderSource(GLuint shader, GLsizei count, GLchar const** string, GLint const* length); It resides in foo() which receives a vector "data" from elsewhere Code: void foo(std::vector<std::pair<GLenum, GLchar const*>> const& data); To pass the pair's second element to glShaderSource's third argument, I do the following:
1. Can I initialize a char const** via initialization list, the way I do a char const*?
Code:
// this works std::vector<std::pair<GLenum, GLchar const*>> const shader_sources = { {GL_VERTEX_SHADER, "sourcecode"}, {GL_FRAGMENT_SHADER, "sourcecode"} }; // but is this possible?
I have a C program. Within it, I would like to embed either a file or a pre-assigned variable. I would prefer a method that is platform independent.
I am using the data type "RSA" from <openssl/rsa.h>. I have a key file in PEM format, but I would like to embed an RSA object in the program instead. I tried creating a char array and then casting the pointer, but that caused some sort of illegal casting issue. I tried using memcpy but I haven't been able to get it working that way. What is the best way of going about this? Is it possible to read a file directly from a memory buffer?
Is it possible to create a dynamic char array on the fly directly from stdin? I do not want to create a fixed length array before hand and then copy contents of it into a malloc created array.
Code: //[1] char line[MAX1]; gets(line);
[Code]....
I could do either [1](buffer overflow problem) or [2] and then goto [3]. But both will have a problem if the input is more than the size MAX1(use defined).
Is it possible to do something of the effect of readLine() method of BufferedReader class in Java or the Console.readLine in .NET? Is it possible to peek into stdin and see the size of the input and then creat an array of the same exact size?
Exporting the data from the sql database to excel directly.this code is not working and i am not getting file in particular location. My connection string is :
Data Source=aswin-pcsqlexpress;Initial Catalog=pro;Integrated Security=True
using Excel=Microsoft.Office.Interop.Excel; using System.Runtime.InteropServices; namespace WindowsFormsApplication5 { public partial class Form1 : Form { SqlConnection con = new SqlConnection(ConfigurationSettings.AppSettings["SqlCon"].ToString());
Below code produces run-time segmentation fault (core dumped) when execution reached line 53: delete [] array
Code 1:
#include <cstdlib> #include <iostream> using namespace std; #define QUANTITY 5 class Parent { protected: int ID;
[Code] ....
Output of code 1:
Constructor of A: Instance created with ID=1804289383 Constructor of A: Instance created with ID=846930886 Constructor of A: Instance created with ID=1681692777 Constructor of A: Instance created with ID=1714636915 Constructor of A: Instance created with ID=1957747793 A::showID() -- ID is 1804289383 A::showID() -- ID is 846930886 A::showID() -- ID is 1681692777 A::showID() -- ID is 1714636915 A::showID() -- ID is 1957747793 Try to delete [] array.. Segmentation fault (core dumped)
Question: Why does segmentation fault happen in code 1 above?
Now i want to be able to change some settings at runtime using a normal Winforms App. Is there a good and easy way to change the user.config of a different application directly? I tried with ConfigurationManager but that does not seem to work.
I am trying to query dates between two textbox values converted to datetime in C#. The dates are returning in the correct datetime and no conversion problem exists there.
However when I run the below LINQ to SQL query in C# it returns no enumerable results. But if I take the below code:
DbCommand dc = dbHistoryContext.GetCommand(qryRes); Console.WriteLine(dc.CommandText);
and get the results as a string of text and cut and paste that into the SQL Server Management studio and execute it - then it works. What do I need to do to search between two dates so that it properly works. The field is of format Date in SQL Server if that matters and the fields being used to pass the information to it are DateTime. The compiler doesn't show any errors but it just doesn't return results.
var qryRes = (from res in dbHistoryContext.tblR where res.updateddate >= dtDateFrom.Date && res.updateddate <= dtDateTo.Date select res);
I have a strange problem in using C code. I want to move focus from one item to another in a keypress event (like keydown)in loop. But it move directly to the last item
Details: In the code segment, I am generating keypress event explicitly from code and want to move focus for number of items inside loop. Loop is working properly, but output is also generated after completion of loop and focus is directly coming on last item in list not showing intermediate movements. Voice output using espeak is generated correctly in each iteration.
Tryouts: I have tried to call a dilog box which take yes/no event by Btn press,that works fine. That means event generation in code is giving problem, it needs h/w intervention for keypress (As I understood)..
