Making two Windows using CreateWindowsEx()
- by Jamie Keeling
Hello,
I have a windows form that has a simple menu and performs a simple operation, I want to be able to create another windows form with all the functionality of a menu bar, message pump etc.. as a separate thread so I can then share the results of the operation to the second window.
I.E.
1) Form A opens Form B opens as a separate thread
2)Form A performs operation
3)Form A passes results via memory to Form B
4)Form B display results
I'm confused as to how to go about it, the main app runs fine but i'm not sure how to add a second window if the first one already exists. I think that using CreateWindow will allow me to make another window but again i'm not sure how to access the message pump so I can respond to certain events like WM_CREATE on the second window.
I hope it makes sense.
Thanks!
Edit:
I've attempted to make a second window and although this does compile, no windows show atall on build.
//////////////////////
// WINDOWS FUNCTION //
//////////////////////
LRESULT CALLBACK WindowFunc(HWND hMainWindow, UINT message,
WPARAM wParam, LPARAM lParam)
{
//Fields
WCHAR buffer[256];
struct DiceData storage;
HWND hwnd;
// Act on current message
switch(message)
{
case WM_CREATE:
AddMenus(hMainWindow);
hwnd = CreateWindowEx(
0,
"ChildWClass",
(LPCTSTR) NULL,
WS_CHILD | WS_BORDER | WS_VISIBLE,
0,
0,
0,
0,
hMainWindow,
NULL,
NULL,
NULL);
ShowWindow(hwnd, SW_SHOW);
break;
Any suggestions as to why this happens?
