HI,

Please clarify my doubt.

How many maximum Documents and View will be available in SDI ?

How many maximum Documents and View will be available in MDI ?

Thanks,
Krishna

The number of documents and views are limited only by memory.
The documents and its views in an MFC application are stored internally in linked lists.

So you shouldn't worry about this.
If you have reached the limit and are unable to add more, there is something seriously wrong with the program and needs a re-design.

That's true for MDI but for an SDI, you only have one document.

Thanks Cédric,

1.In SDI only one Document will be there or one Document at a time we can load ?

2.How many views in SDI is one View or Many ?

Thanks,
Rayalu

1. I don't get your question. In a SDI application, you can only have one document loaded at a time in memory. Of course, you can load another document but then the old document is replaced by the new one. You always work with only one document. Does that answer your question ?

2. As many as you like (and what the memory allows).

Unless you want to do some real fancy footwork you can only have one document in an SDI application. This is due to the limitation of only having one frame window per instance of the application with MFC out of the box. There are ways you could get 'round this but they're probably not worth doing. With MDI apps you can have as many frame windows as you want so as many documents as you can fit in memory.

You can have as many views per document as you want with the limitations of what can fit on your screen.

Cheers,

Ash

SDI is short for Single Document Interface, MDI for Multiple Document Interface. So that's that. As for views, you can have as many as you like as long as they fit into memory. You can even have more than can be shown at a time on screen if you'd like, since you can dynamically change what views you want to be visible.

I have it down to one error I can not fix

here it is

Error	1	error C2660: 'CBaseEntity::isFaceing' : function does not take 1 arguments	C:\Users\Josh\Desktop\pXi_r1430\src\CZoneHandler.cpp	356	1	PXI<br />

Here is the code in question

if(mob->hasBehaviour(AGGRO_SIGHT) && mob->isFaceing(schar->loc.p)) { // and in view and not usign invis<br />
            if((CUtil::distance(schar->loc.p, mob->loc.p) <= 15 )) {<br />
                mob->aggroChar(schar);<br />

Here is the function ( I think tis what it is called )

bool CBaseEntity::isFaceing(struct position p, int coneAngle) {<br />
	<br />
	//Entity's true heading<br />
	unsigned char truerot = (unsigned char)this->getRot();<br />
<br />
	//Desired heading.  Although it is extremely rare to have identical x or z coordinates, this should avoid division by 0.<br />
	if((p.x - this->loc.p.x) == 0) { <br />
		p.x += 0.001f;<br />
	}<br />
<br />
	if((p.z - this->loc.p.z) == 0) { <br />
		p.z += 0.001f;<br />
	}<br />
<br />
	float angle = atan2((p.z - this->loc.p.z),(p.x - this->loc.p.x)); //Arctangent of the slope of the line between entity and target.<br />
	unsigned char rot = (unsigned char) ((2 * 3.14159265358979f - angle) * 256 / (2 * 3.14159265358979f)); //Adjust from radians to SE's 256 degree system.<br />
	<br />
	unsigned char diff = (unsigned char) (abs(truerot - rot)); //The absolute value of the deviation from desired heading.<br />
	<br />
	if(diff <= coneAngle || diff >= (256 - coneAngle)) { //Allowed deviation.  The second case is if the target is due east (compare 254 to 2 for example).<br />
		return true; //Within acceptable range.<br />
	}<br />
<br />
	return false; //Not within acceptable range.<br />
<br />
}<br />

Any help here is greatly appreciated

It seem to me the compiler is telling you exactly what's going wrong.
The function CBaseEntity::isFaceing is defined as follows:

bool CBaseEntity::isFaceing(struct position p, int coneAngle)

I have underlined it's two parameters.

You're calling it like this:

mob->isFaceing(schar->loc.p)

Here your only using one parameter.

So I modified and added twoparameters and now I am getting

Error	1	error C2036: 'regions *const ' : unknown size	C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\vector	879	1	PXI<br />

Here is the code in question

	//Try to use status effects on the entity<br />
		for(unsigned int i = 0; i  <this->statusEffectContainer->m_statusEffectList.size(); i++) {<br />
			CStatusEffect * tmpEffect = this->statusEffectContainer->m_statusEffectList.at(i);<br />
			if(tmpEffect != NULL) {<br />
				//Check tick time<br />
				int tmpTick = tmpEffect->getTickTime();<br />
				if(tmpTick != 0) {<br />
					if((time(NULL)%tmpTick == 0) && tmpEffect->m_lastTick != time(NULL)) {<br />
						//Now execute tic effects<br />
						CLuaManager::OnEffectTick(this,tmpEffect);<br />
						tmpEffect->m_lastTick = (unsigned int)time(NULL);<br />
<br />
					}<br />
				}

Here is the recomendation for what I am supposed to do acording to msvs

If the definition of regions included? Also, surround code with <pre> tags so we can read it.
