'initializing' : cannot convert from 'void *' to 'int *'

Hello, I can someone tell me why I get this error? I tried to run a source code for the WINAPI for a program tutoriol, the one I posted in another post. it gives me the error in the title. What could it be? "cannot convert from void * to INT*"?

The source code for the tutoriol works when I downloaded it. so I don't know why it does that.

Can you post the source code that is causing errors?

If you are using a c++ compiler that error usually means you have to typecast the return value of a function that is returning void*. But can't be certain because we can't see your code and I'm not going to hunt all over this board to try and find the code you previously posted.

Code:

---

case IDC_REMOVE:
                                {
                                        // When the user clicks the Remove button, we first get the number
                                        // of selected items

                                        HWND hList = GetDlgItem(hwnd, IDC_LIST);
                                        int count = SendMessage(hList, LB_GETSELCOUNT, 0, 0);
                                        if(count != LB_ERR)
                                        {
                                                if(count != 0)
                                                {
                                                        // And then allocate room to store the list of selected items.

                                                        int i;
                                                        int *buf = GlobalAlloc(GPTR, sizeof(int) * count);
                                                        SendMessage(hList, LB_GETSELITEMS, (WPARAM)count, (LPARAM)buf);
                                                       
                                                        // Now we loop through the list and remove each item that was
                                                        // selected. 

                                                        // WARNING!!! 
                                                        // We loop backwards, because if we removed items
                                                        // from top to bottom, it would change the indexes of the other
                                                        // items!!!

                                                        for(i = count - 1; i >= 0; i--)
                                                        {
                                                                SendMessage(hList, LB_DELETESTRING, (WPARAM)buf[i], 0);
                                                        }

                                                        GlobalFree(buf);
                                                }
                                                else
                                                {
                                                        MessageBox(hwnd, "No items selected.", "Warning", MB_OK);
                                                }
                                        }
                                        else
                                        {
                                                MessageBox(hwnd, "Error counting items :(", "Warning", MB_OK);
                                        }
                                }

I hope it's not too confusing as I don't really know how to post the coder and in what way you want it. Thanks for ur help

Code:

---

int *buf = GlobalAlloc(GPTR, sizeof(int) * count);

---

That is valid in C but not C++. In C++, you would need to cast the GlobalAlloc return as an int* like:

Code:

---

int *buf = (int*) GlobalAlloc(GPTR, sizeof(int) * count);

---

However if no C++ dependent things reside in the code, I would simply make it a C project.

thanks, it worked. Now i have another problem:

Code:

---


        case WM_CREATE:
                {
                        HFONT hfDefault;
                        HWND hEdit;

                        hEdit = CreateWindowEx(WS_EX_CLIENTEDGE, "EDIT", "",
                                WS_CHILD | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL | ES_MULTILINE | ES_AUTOVSCROLL | ES_AUTOHSCROLL,
                                0, 0, 100, 100, hwnd, (HMENU)IDC_MAIN_EDIT, GetModuleHandle(NULL), NULL);
                        if(hEdit == NULL)
                                MessageBox(hwnd, "Could not create edit box.", "Error", MB_OK | MB_ICONERROR);

                        hfDefault = GetStockObject(DEFAULT_GUI_FONT);
                        SendMessage(hEdit, WM_SETFONT, (WPARAM)hfDefault, MAKELPARAM(FALSE, 0));
                }
                break;

'=' : cannot convert from 'void *' to 'struct HFONT__ *'
Conversion from 'void*' to pointer to non-'void' requires an explicit cast

That's from another tutoriol, would i do something diffrent? or the same thing?

Hmmmmm, the controls program compiled fine but wont open for some reason. This is strange. No idea why it wont open
