If( false == true ) ... C++ enter in the code

Hi all,

I'M using VS.net 2003.

I'm following my code and at some point I found that the test I'M doing seems to not work at all...

Code:

---

        if ( false == true )
        {
                m_Type = GL_RGB;
                m_NbComp = 3;
        }

---

It's going in the m_Type = GL_RGB, and so on...

It's an importer from 3dsmax, one model was working good, I made some changes and it stop working, because of the lines over...

On the other model, it was the new that was crashing. Both are crashing around almost the same code, maybe the error is linked.

Here's the code before my function :

Code:

---


//In the main
        char* ImportFileName = "gob.amd";
        printf("%s\n",ImportFileName);

        if( data.m_Modele.Creer(ImportFileName) )

.
.
.

// In the m_Modele.Creer Function
                        if (Withalpha)
                        {
                                monomat->m_Tex = new Texture(TextureName,TexAlphaName,false,true);
                        }
                        else
                        {
                                monomat->m_Tex = new Texture(TextureName,true);
                        }

//
Texture::Texture(const char * File, Boolean GenID)
: m_Type(0), m_NbComp(0), m_Height(0), m_Width(0), m_ID(-1), m_Texels(NULL)
{
        Creer(File,GenID);
}

//Now the place that it is crashing
void Texture::Creer(const char * File, Boolean GenID)
{
        if (m_Type)
                Detruire();

        BMP_24bits BMP;
        bool loadOk = LoadBMP(BMP,File);

        loadOk = false;

        if ( loadOk ) // false == true is entering here
        {
                m_Type = GL_RGB;
                m_NbComp = 3;
.
.
.
}

//This function return false because file dosen't exist.
Boolean LoadBMP(BMP_24bits & BMP, const char * BMPFileName)
{
        FILE                        *fichier;
        unsigned char        Header[0x36];
        unsigned int        DataPos,DataSize;
        int                                Components;
        long                        NbPixels;
        int                                rest,i,offset;
        unsigned int        linesize;
       
//Read file and header
        fichier = fopen(BMPFileName,"rb");if (!fichier) return false;
 .
 .
 .
}

I don't know what to search in the MSDN, this bug is too weird!

By the way, I've rebuild all my code just to be sure that it wasn't a bad compilation problem.

Thanx for the help!

Use the debugger to check the value of loadOk. Make sure it is set to false when you think it is and watch it as you step through to see if some other code modifies it accidentally.

Also note that LoadBMP returns a Boolean (whatever that is), but loadOk is a bool that gets its value. Perhaps a Boolean and a bool are not compatible.

I'Ve found my error, damn stupid ... I change the code in my lib, but I didn't recompile the lib so I used the old version...

... Thanx daved for the help

Sorry, I am asking it for myself.

Code:

---

if ( false == true )
        {
                ...
                }

---

What does it mean? It will never enter the block.

[EDITED]

It should never enter the block. The expression false == true is false because false does not equal true.

Sorry I knew I just typed wrongly

I don't think the OP was using that code exactly. I think he or she expected the variable to be false and was confused by the code inside the block was being executed.

Ok I didn't explain well why it was entering the block.

I have a library (.lib) and I made a change in a .cpp of this library in the program that I show the code. The thing that is happening during debugguing time is that the compiler just show that it is on line 382 and after on line 384, no matter if the .cpp has been changed, it's reading the library code, BUT show the .cpp code!!

So before recompiling my library ode, I had no if( false == true ) so the compiler just read the instructions that were there before!! This is why it was executing the code inside my false condition.
