    using structs

    I defined structs some structs and I get errors that on the left of '->' must be a class/struct/union. I don't know what is the problem because there is a struct on the left side of '->'. Here is my code.

    I get errors where I used the info variable.
    struct POINTAPI{long X;	long Y;}
    struct TXTFONT{short Height; short IndentX; short IndentY; short Left; short Top; short Width;}
    struct HDCINFO{long HDC; long Height; long Width;}
    struct OUTINFO{TXTFONT Font;  HDCINFO HDC; POINTAPI Point; long StrLen;short ScrollX;}
    [DllImport("gdi32.dll", EntryPoint="TextOutA")]
    static extern int32 TextOut (long hdc, long x, long y, char * lpString, long nCount);
    void _stdcall PrintText(char *pText, OUTINFO *info);
    BOOL APIENTRY DllMain( HANDLE hModule, 
                           DWORD  ul_reason_for_call, 
                           LPVOID lpReserved
        return TRUE;
    void _stdcall PrintText(char *pText, OUTINFO *info){
    	long NextStart, I;
    	bool MoveIt;
    		if(*pText==(char)10 || *pText == (char)13){info->Point.Y = info->Point.Y + info->Font.Height;
    			info->Point.X = info->Font.IndentX - (info->ScrollX * info->Font.Width);
    			if(info->Point.Y > (info->HDC.HDC-1)){break;}
    			if(info->Point.X > info->Font.IndentX){
    				if(info->Point.X > (info->HDC.Width-1)){
    					for( ;I < info->StrLen;I++){ if(*pText == (char)10){break}pText=pText+1;}
    			info->Point.X = info->Point.X + info->Font.Width;
    			pText=pText +1;
    Any one know what is wrong?

    Thanx in advance!

    struct POINTAPI{long X;	long Y;}
    Don't you need a ; after the closing brace as well?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
