i have seen a lot of programs that have images inside their exe, dont use external ones. I tried to add image in my codeblocks project, but trying to use it failed. It seems that to use a resource i have to add some kind of header file, but how to do this???
View 2 RepliesI have 10 or so .sql scripts (the number is likely to rise) which are required to be kept with a C# application.
For the most part the embedded resources seem to work fine , however I require a way in which to guarantee the ordering in which the files are run.
What I do currently:
Retrieve the details of the embedded resources using : Assembly.GetManifestResourceNames()
(and a bit of linq to filter based upon my requirements) which I pass to a list, I then later on use the list to grab the physical resource when its needed.
The files are named such as:
1_ScriptDescription.sql
2_ScriptDescription.sql
3_ScriptDescription.sql
10_ScriptDescription.sql <--- Here's my problem! This will come after 1_ScriptDescription.sql
Ideally I need a way in which to order the list or some kind of ordering when I pull from
Assembly.GetManifestResourceNames()
But I'm not really sure of a practical way to do this, I did consider manipulating the string .....
What i'm trying to do is compile a text file to an executable, but the problem is that I want to be able to edit the resource file while in runtime, for example write something on a textbox, hit compile and get the executable file edited by the texbox.
Here's my codedom:
public static bool Compile(string sourcefile, string exefile) {
CSharpCodeProvider ccp = new CSharpCodeProvider();
CompilerParameters cp = new CompilerParameters();
cp.ReferencedAssemblies.Add("System.dll");
[Code] ....
Is there anyway I could do that?
Any utility that would allow me to display the resources in a DLL? i.e. if the DLL contains icons / bitmaps etc I'd be able to view them. I've a feeling that such a tool exists but I can't remember what it's called.
View 1 Replies View RelatedI want to write a template that combines two type of resources:
class someClasses {
typedef someType ElementType;
} template<class T1,class T2>
class combo {

And I want to specify my T1 and T2 has the same ElementType, how can I write my combo class to partial specialize the general case so the ElementType check is at compile time?
I wrote this program to create a list of medical resources and their attributes, a task I have been performing repeatedly lately. I'm still fairly new to C++, so I thought to create a structure "Resource", and then an array of those structures "city[300]". My problem is that the input doesn't seem to be happening: the program runs, but when it prints to screen/writes to the file at the end, all the shows is:
Resource Type:
Name:
Address:
Phone:
Website:
for every resource that was input. All the fields are blank.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
struct Resource {
string typeID;
string name;

I have started to move over to using Unicode, wide character null-terminated strings in my Windows programmes. Accordingly I set the Use Unicode Character Set Visual C++ compiler option. It is my understanding that once you do that the many macros which determine whether you transparently call ...A() or ...W() API functions automatically shift over to calling the wide character variants. As this is a compiler directive, all the choices are made and hardcoded in to the resultant executable at compile/link-time BEFORE it is ever run. Therefore using for example the macro OpenFileName() in the source code instead of specifically calling OpenFileNameW() has no impact on run-time performance.
The next logical step, instead of explicitly using wchar_t is to declare null-terminated string character arrays as TCHAR*. Then, so long as I also employ the tcn... variants of CRT string functions and call TEXT() or _T() macros to create string literals the preprocessor will chose, again transparently whether to create an executable using standard multibyte or unicode wide characters - and their associated functions - all determined by the Use Unicode Character Set switch. That way I can cover both eventualities with the same source code.
So, with all that - I THINK!!! - properly under by belt, I am fairly sure that using TCHAR and its friends will not effect run-time performance at all. However, in his otherwise excellent article the author makes it sound as if using Unicode EXPLICITLY through wchar_t, ...W() API functions and tcn... CRT calls is faster than the TCHAR alternative.
At the end of the day my question is - have I got the right end of the stick; TCHAR makes no difference to executable performance?
I'm trying to step through the machine instructions of a c program. This program needs to be run with a -t flag.
This is what I tried
gdbtui
file prog
layout asm
start
stepi
When I try 'file prog -t' it doesn't work.
I use g++ compiler and need some tips on how to get started with making a c++ GUI. The project I have will need a gui that will allow the user to conveniently invoke executable (the command-line args they take are long and inconvenient to enter manually) and basically print their output streams into a control (e.g. read only textbox). There will be a few graphics involved too (the input for those graphics will be from a file), so I'll need a library that will allow drawLine methods (nothing too fancy, I don't need a gaming library).
Making a GUI in c++. In Java the ability to make a GUI is a part of the native library, so the c++ way seems foreign to me.
I would like to programmatically monitor a directory for new files, and if the file happens to be an executable, I want to prevent it from running. Something like a AV program.
However, I don't know where to start. Simple is best.
I am just wondering if it is possible to send a project to someone via email - In a simple way, almost like you would install software from the internet, maybe a setup file, or something. The compiler I use "Dev C++" creates a .cpp file and an executable. Unfortunately, I cannot send that .exe file. How would you recommend sharing a program?
View 5 Replies View RelatedI have the following code
#include "../header/FileIO.hpp"
#include <fstream>
#include <stdexcept>
#include <iostream>
std::string FileIO::ReadTXT(std::string filePath){
std::ifstream input(filePath.c_str());
[Code] ....
When I run it in Eclipse, it does not open an SDL window, and simply says <Terminated> Test.exe [C/C++ Application]. I can build the project successfully, but it simply won't run. There are no errors displayed.
HOWEVER, if I replace the above code with the code below, it runs fine, and creates an SDL window.
#include "../header/FileIO.hpp"
#include <fstream>
#include <stdexcept>
#include <iostream>
std::string FileIO::ReadTXT(std::string filePath) {
std::string output;
return output;
}
To make things weirder, if I run it in debug mode, even with the first piece of code, it will run and open an SDL window.
On an unrelated note, what does " Can't find a source file at "e:pgiawsrcpkgmingwrt-4.0.3-1-mingw32-srcld/../mingwrt-4.0.3-1-mingw32-src/src/libcrt/crt/main.c"

I develop a software using QT 5 open source IDE. Now my question is two-fold:
1. How can I create the final executable file that I can upload for my users? I understand that runtime DLLs shall be required and I have tried Enigma Virtual Box software for bundling runtime files. It does create the file that I can execute from any folder in my PC. However, surprisingly when I transfer that "boxed" file to another PC, it does not run. Both the PCs have Windows 7 installed on them.
2. Secondly, I see possible future issues with Antivirus Softwares. Apparently when I try to run the boxed exe file, it gets rejected by the Antivirus Software on my PC. Is there a way in which I can get my exe file verified/checked/registered by the Antivirus Softwares so that my users don't face any problems in executing the program.
I cannot afford the QT commercial licence, but I am prepared to buy any economical "setup file generating" software (if it exists).
I'm writing a program that needs to parse executable files. I've got an "executable" base-class, and currently an "elf" class which inherits from it for parsing ELF files, and I will add more parsers (COM, MZ, PE, a.out, MACH-O, whatever) later on.
I want the program to automatically detect which kind of executable it's loading at runtime. It should be easy because every executable format I'm aware of/plan to support starts with a magic number. But because I can't have the parsers not check the file type (what if I re-use the code?), and I don't want to check each file twice (not just for performance, but also because only the ELF parser should know that ELF files start with "x7fELF", etc.) so I've come up with a pretty lazy solution: just try to parse the file with each known parser and have them throw an exception ("exe_type_error") if they can't parse it. If that exception gets thrown, try the next parser; if not, stop.
The remaining problem is how, at runtime, my program will know what parsers are available. I don't want to hard-code it in the main function; instead, I'd like the parsers to "register" themselves as available. That way, if I decide to go down the route of adding new parsers via dynamic linking, I will only have to add an API for dynamic libraries to register their parser, without recompiling any of the main program's code. I also want to do the same thing for another key part of the program (it's a static executable optimizer; it will run a series of "tests" (e.g. "is xor eax, eax faster than mov eax, 0 on this machine?") and optimizations ("if yes, change all mov eax, 0 to xor eax, eax") and I want to load those at runtime too).
I am writing a program which compresses files into .zip files.
Here's my problem: Whenever I want to compress an executable file, my readFile function does not read the entire file. When I extract the .exe I get a very tiny and incomplete file.
Here's the function I use to read files:
std::string miniz_wrapper::readFile(FILE* f, int MAX_FILEBUFFER)
//MAX_FILEBUFFER has a default value of 65536 {
char* tmp;
std::string tmp_s;
int count = 0;
[Code] .....
Prior to reading, every file is opened using fopen with the mode "rb".
I am looking at reducing the size of a compiled executable for easier distribution.
What factors affect the size of an output executable?
Would literally having defined and implemented less functions, would make the exec. smaller? Meaning that instead of have a DLL ( yes im on windows ), I would download the source code of a library and comment out the functions ( and code ) that I am not using -- Would this process decrease the size of my exec.?
Im writing a scientific software where I like to sent a 2D array (5x4) over a named pipe from a server to a client. When im sending a static array (i.e., double res[5][4];), all goes fine and it works perfect, but when I allocate a dynamic array, it provides some nonsense numbers at the client side. I feel it might be caused because I point to a memory that cannot be shared through a pipe. Am I right and how can I pass the dynamic allocated array itself over the pipe.
//Server program
// Create a pipe to send/receive data
HANDLE pipe = CreateNamedPipe(
"\.pipemy_pipe", // name of the pipe
PIPE_ACCESS_DUPLEX, // 2-way pipe -- send and read
PIPE_TYPE_BYTE, // send data as a byte stream
1, // only allow 1 instance of this pipe
0, // no outbound buffer
[Code] .....
So I wrote a program to turn a binary file's data into an unsigned character array for inclusion in an executable. It works just super.
I'm wondering how I can write a program that will perform this operation on every file in a directory and all it's sub-directories so that I can I can include everything I need all at ounce.
