Im feeling generous today. I created a function for you.

DWORD GetPEMachineType(LPTSTR sz)
{
	HANDLE hFile = CreateFile(sz,GENERIC_WRITE | GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);
	if(NULL != hFile)
	{
		LARGE_INTEGER bigInt;
		BOOL diditWork = GetFileSizeEx(hFile, &bigInt);
		HANDLE hFileMap = CreateFileMapping(hFile,NULL,PAGE_READWRITE,bigInt.HighPart,bigInt.LowPart + 0x2000 ,_T("someGUID"));
		if(NULL != hFileMap)
		{
			LPVOID hMap = MapViewOfFile(hFileMap,FILE_MAP_READ,0,0,0);
			if(NULL != hMap)
			{
				HMODULE hModule = (HMODULE)hMap;
				IMAGE_DOS_HEADER * pDosHeader = (IMAGE_DOS_HEADER *)hModule;
				IMAGE_FILE_HEADER * pFileHeader = (IMAGE_FILE_HEADER *)(((LPBYTE)hModule) + pDosHeader->e_lfanew + sizeof(IMAGE_NT_SIGNATURE));
				return pFileHeader->Machine;
			}
		}
	}
}

Checking for user key press while looping

Californian213-Mar-08 7:23

13-Mar-08 7:23

I'm using a "for" loop which repeats many times and has the potential to be time consuming. I want to be able to break out of the loop when the user hits some key to cancel the operation. The only way I have found to do this is to call GetAsyncKeyState from within the loop, and break out of the loop when it indicates a key has been pressed since the last check was made.

Is this a good way to do this check, or is there some other, better way?

Thanks in advance.

Smile | :)

A better way is to give a cancel button, and pump the messages manually within the loop. Smile | :)

Recommendations for language and IDE

I'm going to start getting back "into" some coding again after a hiatus (actually it's a fairly long one, though I did briefly do some stuff for work here). I've always used Visual Studio 6 and C++/MFC. I have a new vista laptop and even after the patches, found that my shiny new VS 2005 that work bought for me doesn't always work properly when writing simple dialog apps with controls. On the whole, that's the kind of thing I would like to do a lot of, though I will try out "proper" MDI applications at some point.

My point is this - I see a lot written now about .NET and C#, am I better off looking at that and learning those from scratch, or should I just refresh and improve my knowledge with C++/MFC in particular. These won't likely be "hardcore" industrial apps, but I would like to write things that are a bit more robust at some point.

I think at work they might well get an old VS installed at some point, maybe even v6, but at home, it seems a shame that I'm a bit suspicious of VS2005 which is newer of course.

Basically, any advice would be welcome, this isn't spam or trying to get controversy or arguments, nor do I really need any cryptic replies like "use what you feel most comfortable with". I'm at a point where I really can think about where to invest a bit of time and self learning and start playing around. If someone can tell me about other IDE's or perhaps quell my fears about VS2005 in Vista (I even read that you need Vista Business - not sure which I have, but I don't have the most expensive version, nor the cheapest) then perhaps I'm Ok just carrying on with simple dialog apps in MFC for now, but am I missing the boat here, is C# and .NET taking over?

Unfortunately, all you're going to get are opinions.

Research the options and decide what's best for you!

I personally would not use VC6 anymore if you have VS 2005.
With VS 2005 and beyond you'll have many more options in one package,
include improved MFC, improved C++ compiler, C++/CLI, C#, ...

But that's just my opinion. Smile | :)

and thanks for yours. I'm sure I did install some kind of 'patch' for Vista but remember that it didn't seem to fix all my issues relating to adding control variables to controls and things like that. I've seen there is a 430 MB VS 2005 SP1 Team Update(what????) and a Vista SP1 Update at 29MB, not sure if they are both part of the same process, I'll see if I can find what it was I installed when i first got the laptop, probably summertime 2007.

cheers!

Oops I forgot about you mentioning VS2005 not working well on Vista... Smile | :)

It should work fine, so something (obviously) is wrong...

I would recommend installing the VS2005 SP1 for sure. Yes, it is huge - pretty much replaces most of VS haha.

Also, if running your apps from the VS debugger, try running VS as an administrator
if not doing so already (this is no longer required in VS 2008).
