Ok, for some reason.... this just aint working!
I am trying to get integer values from a file, but they arnt working for some reason.

Here is where I get the data:

iResolutionX = INT(dbReadString(1));
iResolutionY = INT(dbReadString(1));
iColorBits = INT(dbReadString(1));

Here is where I try to use it:

dbSetDisplayMode(iResolutionX,iResolutionY,iColorBits);

For some reason, the display mode doesnt change.

Your trying to read a string into a integer variable - no wonder it wont change.

dbReadString returns a char * so you are creating an int, and assigning it the address of the pointer (not the address of the data the pointer is pointing to), some string functions in C++ return an int which holds the address of the first char in a string! you can use atoi( char* ) to cast a string into an int, or dbVal( char* ) either will work.

dbVal doesnt work, but atoi does

It says dbVal is an undeclared identifier.

Thanks =)

can you not just use:

sscanf( szMyFile, "%d,%d,%d", &nWidth, &nHeight, &nBits );

Where szMyFile contains a string as "800,600,32"

Quote: "
dbSetImageColorkey

This command will set the general colorkey for all images. A colorkey allows you to specify a particular RGB colour that will be treated as transparent by the image when used. Transparent pixels of an image are not drawn. You must use this command before loading or grabbing an image in order that a suitable alpha map be generated from the transparent pixels of the desired image to be calculated. The alpha map is then used to decide which pixels are drawn and which pixels are never rendered.

Syntax
void dbSetImageColorKey ( int iRed, int iGreen, int iBlue )
"


Yeah the dbVal command is missing from the DarkSDKText.h header file, but it is in the library file so the header just needs modifying.
