I don't often use Windows 7 so I might be wrong on this, but as far as I know it comes with a built in 32 bit Windows XP virtual machine? MSVC 1.52 might work in that.

Personally I use Microsoft C 6.0 in DosBox[^] and MSVC 1.52 in a Windows 2000 guest OS with VirtualBox[^], both works.

Thanks for the reply.

Win 7/64 Pro does come with XP virtual machine but unfortunately I only have the Home edition which does not. I thought about upgrading but its too much hassle re-installing everything.

I have a copy of Microsoft C 6.0 somewhere so I think I will give that a go in DosBox.

Can you advise how I install it in DosBox please.

Thanks for the tip. Thumbs Up | :thumbsup:

Upgrading from Home 7 to Pro 7 does not require you to reinstall a thing. All it does, essentially, is replace what's in the Windows folder with the upgraded components, and leave the registry and all program files intact.

Hi Richard,

Thanks for this info. This only applies if you buy the Windows 7 Anytime Upgrade. Even though I have a copy of Windows 7 professional, it will not perform the upgrade - unless anyone knows differently.

Thanks again

Your Product key from your boxed Pro 7 will work as an Anytime Upgrade key. I did that myself on a new netbook I had purchased with Win 7 Starter.

I chose the Anytime Upgrade, and put in my boxed Win 7 product key, and everything went through.

So you're not out of luck.

Try [Microsoft QuickC 16 Bit] IDE/Compiler for the C programming language. Its main competitor was Turbo C. (Quick C vs Turbo C , get it? Cool | :cool:

), Its from the year 1990.

[This] link mentions this:

Emulation
The easiest way to get Turbo C/C++ to run is using DOSBOX which emulates the environment of an old 16bit MsDOS computer. This works very well and will allow you to run most programs (even CGA/VGA/SVGA graphics).
If you wish to run Turbo C on Linux there is DOSEMU.

Virtualization
Another option is to run the programs on a Virtual Machine. Think of this as running a virtual computer on your computer. The VM emulates a PC and you can load an OS like an old copy of windows (if you have old disks laying about) or you can use FreeDOS as an OS.

Thanks for the reply.

As I said earlier, I have used Microsoft Virtual PC and loaded Windows XP 32 bit on it but it was very slow and routinely locked up and lost connection to the host HDD, loosing the contents of any source file I had made changes to Cry | :((

Since them I have installed Oracle VM Virtual Box which seems (so far) to be a much better product.

Thanks again

SendInput()

Member 801032519-Dec-11 16:29

19-Dec-11 16:29

Hello all. I'm trying to synthesize alt + space to bring up the output window's menu using SendInput(). For some reason it works on other windows that I click on after compiling, but CMD windows just take it as a space key press. Here's what I have:

    Sleep(2500);

INPUT in1 = {INPUT_KEYBOARD};
INPUT in2 = {INPUT_KEYBOARD};
INPUT in3 = {INPUT_KEYBOARD};
INPUT in4 = {INPUT_KEYBOARD};
KEYBDINPUT k1 = {VK_MENU,0,0,0,0};
KEYBDINPUT k2 = {VK_SPACE,0,0,0,0};
KEYBDINPUT k3 = {VK_SPACE,0,KEYEVENTF_KEYUP,0,0};
KEYBDINPUT k4 = {VK_MENU,0,KEYEVENTF_KEYUP,0,0};
in1.ki = k1;
in2.ki = k2;
in3.ki = k3;
in4.ki = k4;
SendInput(1, &in1, sizeof(INPUT));
SendInput(1, &in2, sizeof(INPUT));
SendInput(1, &in3, sizeof(INPUT));
SendInput(1, &in4, sizeof(INPUT));

system("pause");

So this works in other windows and ignores the alt press in CMD windows. Snarl. The alt + space hot key works in CMD windows when I press the keys manually.

Just a guess but it could be that the key handler for those windows you want to target use GetKeyState[^] or GetAsynchKeyState[^] to check if the ALT key is down or not and SendInput does not change what these will return. I guess you could test for this by manually pressing the ALT key and sending the space with SendInput as you do.

you'll need to disable the "run time error checks" compiler option.

Either turn off 'Optimize for speed' or 'Run Time Error Checks[^]' as they are apparently not compatible.

Thanks in advance

What do you really need to do? Do you have to store the integers or their string representation?
