SendMessage EM_STREAMIN

This is my code..

Code:

---

SendMessage(hEditMain, EM_STREAMIN, SF_TEXT, EditStream);

---

The error...

Code:

---

error C2664: 'SendMessageA' : cannot convert parameter 4 from 'struct _editstream' to 'long'
        No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

---

EditStream is a structure. I putting (long) next to it and it wont work. Any ideas?

Try declaring the EditStream structure as long

But then it wont be an editstream structure.

Try passing a pointer using &EditStream (you'll need a cast).

I tired &EditStream, didnt work. Whats a cast?

Code:

---

long location;
char *ptr;
char val = 5;

ptr = &val; // Fine
location = (long)ptr; // Needs the cast to change indirection level

---

Oh ok, i know what those are. Ive tried every combination i could think of of those.

Does it fail to compile, or fail to work properly?

You need to convert it to LPARAM. Try this:

Code:

---

SendMessage(hEditMain, EM_STREAMIN, SF_TEXT, (LPARAM) &EditStream);

---

Parksie, it fails to compile.

Megatron, i get this error

Code:

---

error C2440: 'type cast' : cannot convert from 'struct _editstream' to 'long'
        No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

Edit:
Megatron, i forgot to add the '&', and it works now. Thanks.
