It's quite possible that the working directory is different for the F5 and Ctrl-F5 run.

If you are opening any files be sure those files exst - best way is to supply a complete path name to your open routines, not just the filename.

Hope that helps.

Need guidance and proposal of design and implementation for an e-voting (electronic voting) system

Hi all!

I want to design and implement an e-voting(electronic voting) system with two computers(one as server and the other as client) under windows;
What technology or programming model do you suggest me for this purpose?
I'm not familiar with network programming models in windows and need help of experience people!
One guy have suggested me to create an ActiveX on client and communicate with server through COM, what do you think about it?

Please help me!!!
Best Regards.

Personally, I'd probably approach it by exposing a web-service[^] interface on the server that the client could use.

I wouldn't use COM because I've heard too many painful things about configuring COM to work across multiple machines. But that's just my prejudices Blush | :O

i have created a dialog and the dialog font size is different with my friend (all the setting in a property page is totally the same). Have anyone face this problem before?

CreateObject with specific constructor

Hello,

is it possible to create an object with the CRuntimeClass-pointer and call a specific constructor during the creation, similar to the function new?

Maybe I can combine the CRuntimeClass-pointer with the funktion new?

CRuntimeClass* pRTC
CObject* pOb = pRTC->CreateObject();

CObject* pTestObj = new CTesObj( 5 )

Re: CreateObject with specific constructor

If CTesObj is derived from CObject, then "CObject* pTestObj = new CTesObj( 5 )" is what you want.

Thank you for your answer, but my problem is another one:

CTestObj ist derived from CObject.
So I can create the objekt with new, like
"CObject* pTestObj = new CTestObj( 5 )"

But I will create the object with the runtimeclass-pointer (CRuntimeClass* pRTC).
This pointer knows the type of the class and I can create the object with the
CreateObject-function.
CObject* pObj = pRTC->CreateObject();

The CreateObject-function calls the standard-constructor.
Can I call another constructor during creation with runtimeclass-pointer?
The next line did not compile but maybe you can modify it:

CObject* pMyObj = new pRTC( 5 );

At the time of creation, I only know the runtimeclass-pointer and the transfer
parameter (5).

In my program the transfer parameter is a big class. So I will save time during creation.

Do you have an idea?

ANSI to UTF8 (dynamic mem alloc?)

Good morning Smile | :)

,

got a question to the following code piece which converts ansi text to UTF8.

void SynthesizerSvox::ANSI2UTF8( char* text, int size, char*& result )
{
	const int SIZE = 10240;

	if( result ) 
	{
		delete [] result;
	}
	result = new char[SIZE];
	
	WCHAR w[SIZE]={0};
	int erg=0;

	erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, SIZE / sizeof(WCHAR));	// ANSI to UNICODE
	erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, result, SIZE, 0, 0);		// UNICODE to UTF-8
}

I found the code somewhere on the net (thanks!) and it works nicely. Only I´d like to work with dynamic memory allocation (don´t like to limit it) and can´t seem to get it done. The number of bytes used per character vary in UTF8 character set.
Is there a solution to this?

Why?

Yes, but WideCharToMultiByte is able to tell you how many bytes are required (MSDN [^]):

cbMultiByte [in]

    Size, in bytes, of the buffer indicated by lpMultiByteStr. If this parameter is set to 0, the function returns the required buffer size for lpMultiByteStr and makes no use of the output parameter itself.

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

How to access a remote machine from a local machine and perform basic function like execute and close the remote machine's application.

Hi,
I am using VC++ . I want to access remote machine and then peroform functions like

1- View the applications of remote machines by clicking on the start of local machine
2- Select any application such as MS word of the remote machine by using mouse
3- Close the application by using mouse.

I guess technically I have to access the remote machine explorer.exe at my local machine.

How this stuff can be acomoplished in VC++? any idea

I would appreciate the guidance.

The free edition of RealVNC[^] is open source. I was forced to hazard a guess of what you're trying to achieve, but I also think that you've not had a chance to read the guidelines[^] in your 7+ years here?

Also, a there is a comparison of remote desktop software[^] (you may see what is open source, and what might suit your needs)

That's what I see here now, but what I received in the email notification was entirely different! You've changed it immediately after posting to appear innocent.

If you don't have the nerve to make a comment publicly, you might as well hide under that same hole where you were. You want to know what I think? I think that you are a complete idiot. You are clearly in no position to assess anybody's contributions here.

YES- We wrote these lines and then we deleted that if you have not courtesy/moral values then at least we should show and there is no need of hiding. Basically we two persons are working over this project. The other person does not bear user account with this portal and was using mine.

and once again you proved from your language that where you morally stand. I am not intrested to know what are your contributions. Only cheap like you requires praise.

You post one thing, and then edit it later to look innocent (just change it to "thanks" - wow! Roll eyes | :rolleyes:

). And I'm cheap because why? Was there anything vulgar or abusive in my reply? I insist that you read the guidelines and that makes me morally low?

You said there was no 'content' in my reply, but besides asking OP to read the guidelines, I also provided inputs that should have helped. You have no comments about that, but you insist on judging me otherwise?

Ignorance must be bliss!

In my first post, I only asked to read the guidelines! You then wanted to prove your idiocy by behaving like a criminal. As you can see, we are not hiding behind anything, are not anonymous and are here for a purpose. Unfortunately, shameful people like you refuse to follow the guidelines and keep posting elementary stuff.

You will be ignored.

ALL of these words are used by you , not by me and I have no doubt that you deserve all these titles. I used the words idiot only when you used it for me as a response and still I am excusing you. Indeed you are a totaly technology nut having no content (innerself) and you should be proud over.

See it for yourself:

2. I ask you to read the guidelines (along with an answer - links to open source implementations of the stuff you asked for).
3. You send me a stupid reply and then modify it so that it won't be visible publicly (changed it to "thanks"). You are a tosser.
4. Now, you think I cannot call you an idiot? And you are not a shameful person? Actually, YOU ARE.
5. And you think that I am ignorant.
