I'm tyring to create a memblock in my DLL. When I do so, the pointer to the g_pGlob->g_Memblocks is empty which means the DBP program has not compiled in the memblock dll and has no instance to it?

If I add:

Make memblock 1,1

to my DBP code, then it works as the pointer is there so I can use it in my DLL. What am I missing?

Nothing.

You need to make sure that the required DLLs are included in the compile process by DBPro by using a command from the DLL.

Ok. I have a command in my DLL called DBPMakeMemBlock(). When I call it, it crashes because g_pGlob->g_Memblocks is 0x00000000.

So is this what you mean by calling a command from the DLL? It is what is causing the crash.

Hm...perhaps he means like what sparky's collision dll and stuff like that does,include a memblock command in your dbp code. Just something simple like if memblock exist(1) then a# = 1. I'm not sure if thats what he means,but it may be.

all ben needs is his band,his guitar,and his computer

Yes.

It's the compiler that decides which DLLs are included with your EXE, so including a memblock command within your DBPro code will include the memblock DLL. You don't even have to run the command to do this:

AH. Ok thats what I was doing. But it seems that other instances are there without having to use them so I thought maybe it was a problem elsewhere.

I was hoping for a way around it so that if someone else uses my DLL, they may never figure out why it crashes.

I guess I'll have to just do a check if the memblock instance is NULL then pop up a message.
