Add Message Handlers for EN_HSCROLL and EN_VSCROLL messages and display MessageBox there.
Now, I hope you know how to add message handlers. If you dont, u can find it in any basic level MFC Book.

Use CButton if you are using MFC
use HBUTTON hBut=(HBUTTON)CreateWindow("BUTTON"......); in WIN32apis

Try rebuilding the project. Or just ignore it and run program further by pressing F5.

Dear friends,
I am declaring a template class in header file and defining its methods in cpp file. As such i am getting an error of "unresolved external symbols" whenever i create object of this class.
Instead, if i define the methods in *.h file and remove cpp file, the errors are removed and program runs fine. Can anyone tell me whats the problem:
////////////////////////////////////////////////////////////////////////////
// File MyTemplate.h
template <class T> class TMyTemplate
{
public :
TMyTemplate();
~TMyTemplate();
};
template <class T>
TMyTemplate<T>::TMyTemplate()
{
}
template <class T>
TExpandableBuffer<T>::~TExpandableBuffer()
{
}
/////////////////////////////////////////////////////////////////
i.e i declared and defined functions in header file and this works fine for me. But if i remove the methods definition from header to cpp file the compiler starts giving me error of "Unresolved External Symbols" whenever i create object of class like:
TMyTemplate<char> myTemplate;

To Call Exe File in VC ++ you have to use the Buildin Function
"Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long"
Hwnd as user Handle
lpOperation as operation i.e. "open","print"
lpFile as path of exe file

you can use ShellExecute to call any exe from ur application
|
|
|
|
|
theer are numerous apis for achieving that like
<ul>
<li>ShellExecute/ShellExecuteEx
<li>WinExec
<li>CreateProcess
</ul>
|
|
|
|
|
HANDLE hProcess = NULL;
SHELLEXECUTEINFO shellInfo;
::ZeroMemory(&shellInfo, sizeof(shellInfo));
shellInfo.cbSize = sizeof(shellInfo);
shellInfo.fMask = SEE_MASK_FLAG_NO_UI | SEE_MASK_NOCLOSEPROCESS;
shellInfo.lpFile = your app file;
shellInfo.lpParameters = NULL;
if(::ShellExecuteEx(&shellInfo))
{ /* success */
hProcess = shellInfo.hProcess;
if(hProcess != NULL){
::WaitForSingleObject(hProcess, INFINITE);
::CloseHandle(hProcess);
}
}

My class uses mathematic operation (time critical) and i want the window with progress bar appear, but i couldn't create a dynamic window, i tried this:
CWnd * pWnd = new CWnd;
pWnd->Create("asdf","asdf");
pWnd->ShowWindow(SW_SHOW);
But it doesn't work.
And another question = how to create a dialog window dynamically without using the resources?
|
|
|
|
|
is there a particular reason why you don't want to use the resources ? I would make your life simpler ...
BTW, you can't create a dialog by just using CWnd.
you need to create a DLGTEMPLATE and call InitModalIndirect ...

like this:
::ShowWindow(::CreateWindow("Button","Button1",WS_CHILD|WS_VISIBLE,10,10,100,50,m_hWnd,NULL,AfxGetApp()->m_hInstance,NULL),SW_NORMAL);

I'm writing a (COM-based) toolbar for IE. At some point I found "new" returned NULL whenever the data size became larger than 300K.
Then I tried ::HeapCreate to create a heap of initial size 1M, but when I used ::HeapAlloc to allocate a chunk of 500K, it said "not enough quota". (It works when the size is 300K, though)
Then I used IMalloc::Alloc to allocate memory, and allocating 1M memory succeeded.
I'm totally puzzled why new and HeapCreate failed and IMalloc would succeeded. Is there some kind of limit on the memory size of a DLL(as my toolbar is compiled into a DLL which is loaded by IE)?
Anybody has any idea?
Thanks a lot.
