Managed C++ And C++/CLI :: How To Create EXE File To Run It On Any Window
May 11, 2014
I have created a MFC application on Visual c++ 2012. My computer work in Win 7 - 64bits. When I see many tutorial about making the executable file which is independent on .dll library (by changing Configuration Properties ->C/C++->Code Generation->Runtime Library ->Multi Threaded Deburg (MT/d)) the compiler becomes error then I can not get the result as tutorial on internet.
Is there any other way to make the .exe file for this?
I am developing an app that shows a pixelated picture in a window. I am trying to capture the image, which is composed of a number of tiles processed from a mother image, but I am having difficulty since I can't reference the image on the screen. I have placed a rectangle around the image and my understanding is that I have get the window handle for the rectangle in order to save the Image as a jpg file. In the literature there is something about a Device Context and a window handle but my compiler throws out HWND and I don't really understand the device context. I am using Windows Forms, not native code.
Right now, I have and application that opens a multi file dialog box. I want to take all of the files I highlight when the dialog box shows up and display a messsage box with the path and file names. This is what I have right now:
Currently, it only shows the first file that I choose. I want to make it so that the message box shows all of the files that I select when the open file dialog shows up.
There is function written C++, that must be compiled to DLL. This DLL is linked to some CAD (computer aded design) tool, that has special interface for it.
I want to add to this function some GUI (graphical user interface). So the creation of a window is necessary.
I've tried already with Win32, but without success.
The problem is that CreateWindow function requires application instance handle, that is provided by Windows itself when window is created in "normal conditions".
I'm trying to port a Win32 application over to Windows Forms so that I can have better graphical control over the interface. The program itself is pretty simple; in the main message loop it listens for a WM_CopyData containing a certain char array, and occasionally sends WM_CopyData itself after the user clicks a certain sequence of buttons.
I found a couple of pages discussing how to completely override the Windows Forms WndProc, but I rather like having the framework do all of the control and would prefer to only latch onto it, rather than replace it. So, what would be the best way to have a Win Forms application listen for Windows Messages continuously and execute a function upon receiving them?
If I do need to override WndProc, what is the syntax? I found the following code:
Code:
protected override void WndProc(ref Message m) { base.WndProc (ref m); if (m.Msg==0x4a) // WM_COPYDATA { // do your stuff here... } }
But when I stick that into my main.cpp file right after int main function, "protected" gets highlighted as a syntax error with the message "IntelliSense: expected a declaration".
I am working on my project of gesture recognition using c++ and open cv and i am also designing GUI simultaneously. I am using system namespace for GUI part and cv namespace for gestures.
After compiling i am getting error as Ambiguous symbol String is used.

I'm pretty much newbie in creating a successful GUI in C++. Although, i managed to create 4 buttons that should show a certain form. Lets say, Form1 is my main form, therefore - Button 1 will open Form2, and Button 2 will open Form3..... But the conditions is - If there is a form that is already open, clicking again on the Button that should open it, will Close it, but all the forms (form1,2,3,4,5) can be enabled together.
Also, a very important note is that whenever i close a form, in any way of closing it (Not the main form) It will "save" the changes i made (Such as ticking checkboxes and so..) and won't reopen it, it will just use "Visible" i guess ?
Notes :
If i use Form2 ^form2show = gcnew Form2;
and then Form2->Show();
I will be able to simply ATTACK the button and open Billions of form2 ^_^
Although, when i use Form2->ShowDialog();
It won't let me open the form3,4,5.
Which isn't so bad, but when i exit from the form2, it won't save my changes (Such as checkboxes..)
I need to create a project that create a automated backup of a file.
i will get the file from C:/Folder/file.exe and move for a other created folder, but.. in every time that user make this backup, a folder will be created with year, month and date, like: C/Folder2/2014/April/16:42/file.exe.
I'm trying to make sure my code is written in smaller modules, so my first step is to create my initialization process in and external file to load the necessary data from external sources and set up things like the content of drop down list boxes.
My first attempt failed to give me access to the combobox items add function so I moved that code back into the form1.h file:
Code: public: Form1(void) { InitializeComponent(); // //TODO: Add the constructor code here // } void AddDate(char *date, int ID) { this->comboBox1->Items->Add("line 1"); }
It compiles fine, but the call to it in my Initialize.cpp file
Code: MarketView::Form1::AddDate("abs",1); Gives error C2352: 'MarketView::Form1::AddDate' : illegal call of non-static member function
OK, so I change "void AddDate" to "static void AddDate" and now get the error that "static member functions do not have 'this' pointers" so I go back to the "MarketView::Form1::comboBox1" situation where there is no legal syntax after "Box1 to get me to Items->Add
I've been an old fashion programmer for over 47 years. It seems as is the concept of programming computers has changed from the concepts of logic to memorization of complex syntax.
There has to be a simple answer to do this other than to write thousands of lines of code in one Form1.h file. I refuse to believe that the new programming concepts will not allow you to write code in smaller more manageable modules.
What is the proper syntax for breaking up the larger file into more manageable chucks?
#include <iostream> using std::cout; using std::endl; int main(int argc, char* argv[])

The only Problem I have is that I need to know how to open a command window at the folder containing the .exe file(this program), inorder to enter the program name or arguments.
1. Load HTML File (or take stuff from string) 2. display window with content of that html
so yeah, basically something like a browser, is there some lib that will just load html and do it for me? I dont need whole browser, I just need to show really simple html pages in my app....
I am trying to open a file and print the contents of the file to the terminal window. It works when I put the file right in the directory with the Solution but not if the file is out on my desktop and I use the full path. Here is the code:
#include <iostream> #include <fstream> #include <string> using namespace std; int OpenFile(){ fstream SampleFile;
The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.
How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?
If "Y" Than Inputs Are Taken From Next Line Else Input Ends.
But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.
Code: #include <stdio.h> void writeFile(void); void readFile(void); int main(){
I am interested in creating a file of a given size and then randomly accessing the file to populate it. Is there a way to quickly create, for instance, a 4 GByte file in C++, initially populated with garbage?
How do you create a save file for a game, that is not a separate file? Specifically I am using code::blocks and sfml 2.1 to make a game and it saves to a text file at the moment. My problem is that it is very easy to modify the text file, and it is annoying to have to copy and paste several files if you want to use a copy of the game. I have a feeling that it may be to do with resource files, but I'm not exactly sure how to get these to work or whether you can modify them dynamically.
I want to create a program that would take an AVI file, alter each frame (ex: change contrast, invert colors, etc.) and dump a new AVI. I've wrote a simple program for this experiment that loads up the header information from the video and dumps it. It also dumps a list of the frame data chunks within the 'movi' chunk.
The info I've gathered from coding this:
1. The recommended buffer size for each type of stream (vids, auds, etc.) is the size of the largest frame of corresponding type, plus 1 or two extra bytes.
2. numFrames in main header is the total number of frames for all types of data (video,audio,etc.) The 'length' value within stream header of type 'vids' is the number of video frames. The sizeImage value within BITMAPINFOHEADER is 921600 (==640*480*3) and the specification states that, quoth, "This can be set to 0 for uncompressed RGB bitmaps."
3. This video uses DIVX encoding.
Now my problem is this: How do I get the data within each video frame in a simple BMP like format? Even the uncompressed frames (with chunk id 'nndb') have variable sizes...let alone the compressed ones.
Information about a software that converts AVIs to a format with fixed sized uncompressed frames. Or at least some information about the frame decompression techniques.
Here's a dump made by the program for a 9 sec, 640x480 video I recorded from Pokemon. (Without the frame dump that is, it'd have made the post too long.)
I now have a file with X, Y, Z and Intensity (0-1) of all the pixels. I want to create a .bmp file (grayscale) with this information in C++. How to do it?
