define window size

brunopescarolli (11)
Hello! I program in C + + ah few months and develop application in console mode and which function in the code would set the size of the application window?

researched some on the internet and tested them, but does not work
which one is correct?

Use Dev C + + compiler 4.9.9.2

Non of the standard libraries support the following:

- Audio
- Video
- Graphics
- Artificial Intelligence
- User Interface Elements

In order for you to do what you're asking, you'd have to pull in your OS's API and call the appropriate functions. Of course, since you've been programming for a couple of months, it's likely that the OS's API will confuse you. It's best to stick with the default size, rather than dive into a unknown territory head first.

...is not a compiler. Dev-C++ uses an old version of MinGW's compiler suite. It's best to update you IDE to Code::Blocks, or Visual C++ Express (the free version).

#include <windows.h>
//função em C++ de configurar tamanho da janela personalizada ".h"

//configWindown.h

void configtela()//função q configura o tamanho da tela e do buffer
{
COORD outbuff;
outbuff.X = 50; // tem que ser 1 maior que o tamanho X
outbuff.Y = 70; // tem que ser 1 maior que o tamanho Y
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleScreenBufferSize(hConsole, outbuff);
Sleep(130);
SMALL_RECT windowSize = {0, 0, 900, 70}; 
SetConsoleWindowInfo(hConsole, TRUE, &windowSize);
}


I tried but does not work, actually do not know how he uses it
I put the file name of "configWindow.h" and then I include in the project thus: #include "configWindow.h"

I did something wrong?, I use Windows Xp

Which means you don't understand what you're reading. Just how much of C++ do you know?

Did "configWindow.h" come with the project?

I am beginner guy ok?

"configWindow.h" I that I created! which has the code I posted above after initially includes the project in order to adjust the window size

Here is a small program I had written, which has a larger console window. I added in a fo loop to shrink it before the program ends. By studying this, you should be able to use the concept in your program as well. Good luck..

@brunopescarolli:

(I know you're a beginner, so just read the bottom paragraph here if all of this goes totally over your head)

The window size can never be larger than the console screen buffer size or the max window size.

In your function, you're most likely trying to set the window size beyond both the screen buffer size and the max window size. (window length of 900 character cells?!)
That's why it's failing.

If you're not familiar with messing with this stuff, don't bother trying to set the window size...
...you won't need to in a majority of cases, anyways.
