Not a coding question but on bordeline, I’ll admit.
When I am using simple one row / two columns splitter window should I refer to left / right pane or view?
Same goes for tab view (or actually control) – is it a tab or view or page?
Similar dilemma for a tree view.
I guess what I am asking is – how to name my class so it is descriptive
CCamera or CCameraView or CCameraTab if it is a AVI frame in “splitter tab” ?
Thanks for reading.

I would go with a and b.

When using a splitter window (or a Frame) I always put Views in each pane, so I would give them names such as IndexView, DetailView etc.
With Tab pages I would use Tab or Form as the suffix etc.
The main thing to consider is whether it makes sense to you and, more importantly, whether it would it make sense to someone else who had to maintain your code.

Hi to All,
I am a beginer in MFC.
I have added a new dialog box (property sheet_Medium) in my dialog based application. Now, i want to put a data-grid on the new dialog. Please tell me where do I write the code(to create the datagrid) for the same?.. I cannot see a OnInit method too. I want to show the grid when the dialog appears
Thanks in advance
-----------------------------
I am a beginner

You should do it in the OnInitDialog function of the dialog.
If you don't see the function, you must add it yourself.
OnInitDialog is a virtual function defined in the CDialog class.
You can override it in your derived class.

Is this the name of your dialog class, or is the class derived from CPropertySheet?

my question is
How can i concate two bitmap to produce third combine bitmap ?
here is my code:
CImage __Imageone;<br />
__Imageone.Load (L"D:\\2009\\testConsult.tif");<br />
<br />
int nWidthone = __Imageone.GetWidth();<br />
int nHeightone = __Imageone.GetHeight();<br />
<br />
COLORREF __colorefone;<br />
<br />
for (int i = 0 ; i < nWidthone ; i++)<br />
for (int j = 0; j < nHeightone ; j++)<br />
__colorefone = __Imageone.GetPixel (i,j);<br />
<br />
<br />
CImage __Imagetwo;<br />
__Imagetwo.Load(L"D:\\2009\\Header.TIF"); <br />
int nWidthtwo = __Imagetwo.GetWidth();<br />
int nHeighttwo = __Imagetwo.GetHeight();<br />
COLORREF __colortwo;<br />
for (int x = 0 ; x < nWidthtwo ; x++)<br />
for (int y = 0 ; y < nHeighttwo ; y++)<br />
__colortwo = __Imagetwo.GetPixel(x,y);<br />
<br />
how to combine these two into one ??
Thanks !!!!

For example:
CImage img[3];
img[0].Load(_T("D:\\2009\\testConsult.tif"));
img[1].Load(_T("D:\\2009\\Header.tif"));
int h, w , bpp;
HDC hdc;
w = img[0].GetWidth() + img[1].GetWidth();
h = img[0].GetHeight();
if (h < img[1].GetHeight()) h = img[1].GetHeight();
bpp = img[0].GetBPP();
if ( bpp < img[1].GetBPP()) bpp = img[1].GetBPP();
img[2].Create(w,h,bpp);
hdc = img[2].GetDC();
img[0].BitBlt(hdc, 0, 0);
img[1].BitBlt(hdc, img[0].GetWidth(), 0);
img[2].ReleaseDC();
img[2].Save(_T("img3.tif"));

Is 'void' a data-type?
If yes then why sizeof(void) shows compiler error?
|
|
|
|
|
void stands for 'no-type-because-there-is no-value' (for instance as function argument or return value) or 'any-type' in expression like
void * p;
Since p can point, for instance, to char as well to double it make no sense an expression like sizeof(*p).

void, in effect, == undefined, so (as it's not defined) cannot have a size.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p
|
|

|
|
Yes, according to the C99 standard: "The void type comprises an empty set of values; it is an incomplete type that cannot be
completed."
Applying sizeof to an incomplete type is an error.

With FindWindow and FindChildWindows API functions, I got the handle of SysListView32 control of mmsys.cpl panel. When I was trying to search the text of each entries on the ListCtrl, it always crashed.
My code snippet is as the below.
void CMainDlg::OnBnClickedGetDolby()
{
KillRunningApplet(_T("Sound"));
if(!LaunchCplApplet(_T("mmsys.cpl"), 0, 0)) {
OutputDebugString(_T("LaunchCplApplet fails. \n"));
return;
}
CWnd* pWnd = NULL;
int i = 0;
while(!pWnd) {
pWnd = FindWindow(NULL, _T("Sound"));
if(pWnd) {
OutputDebugString(_T("Found Sound window. \n"));
break;
}
Sleep(10);
i++;
if(i > 1000) {
OutputDebugString(_T("Sound window is not found. \n"));
return;
}
}
m_hListView = NULL;
for(i = 0; i < 2; i++) {
EnumChildWindows(pWnd->m_hWnd, DoSomethingHelper, (LPARAM)this);
if(m_hListView) {
OutputDebugString(_T("Got SysListView32"));
break;
}
else {
OutputDebugString(_T("SysListView32 is not found."));
if(i == 1) {
return;
}
}
}
CListView* pView = (CListView*)FromHandle(m_hListView);
CListCtrl& Ctrl = pView->GetListCtrl();
LVFINDINFO info = {0};
int iIndex = 0;
info.flags = LVFI_PARTIAL | LVFI_STRING;
info.psz = _T("Speaker\0");
if((iIndex = Ctrl.FindItem(&info)) != -1) {
OutputDebugString(_T("Speaker-like entry is found."));
}
}
BOOL CALLBACK DoSomethingHelper(HWND hwnd, LPARAM lParam)
{
TCHAR sClassName[MAX_PATH] = {0};
GetClassName(hwnd, sClassName, MAX_PATH);
if(wcscmp(sClassName, _T("SysListView32")) == 0) {
CMainDlg* pMain = (CMainDlg*)lParam;
pMain->m_hListView = hwnd;
}
OutputDebugString(sClassName);
return TRUE;
}

Which applicaion crashes? the applet or your application?
|
|
|
|
|
A dialog box popped up saying "Windows Shell Common DLL has stopped working". When I clicked [Close program] of that popup, the applet was gone but my application still was alive.
I traced into the source of MFC. The problem is the m_hWnd of that CListCtrl.
_AFXCMN_INLINE int CListCtrl::FindItem(LVFINDINFO* pFindInfo, int nStart) const
{ ASSERT(::IsWindow(m_hWnd)); return (int) ::SendMessage(m_hWnd, LVM_FINDITEM, nStart, (LPARAM)pFindInfo); }

hmm..
This is because you are passing a string pointer to another process. And when the other process try to access that pointer, exception occurs. You have to allocate the memoy in the target process( VirtualAllocEx() ), copy the string to that process' memory( WriteProcessMemory()). Then set that pointer in the LVM_FINDITEM structure and call FindItem().
|

I did this as the below, but pBuffer is bad_ptr and WriteProcessMemory returns fail.
LVFINDINFO info = {0};
int iIndex = 0;
TCHAR sTxt[MAX_PATH] = {0};
SIZE_T nByte = 0;
wcscpy(sTxt, _T("Speaker"));
info.flags = LVFI_PARTIAL | LVFI_STRING;
TCHAR* pBuffer = (TCHAR*)::VirtualAllocEx(m_hCplProcess, NULL, MAX_PATH, MEM_RESERVE, PAGE_READWRITE);
if(!WriteProcessMemory(m_hCplProcess, pBuffer, sTxt, MAX_PATH, &nByte)) {
return;
}
info.psz = pBuffer;
if((iIndex = Ctrl.FindItem(&info)) != -1) {
OutputDebugString(_T("Speaker-like entry is found."));
}
VirtualFreeEx(m_hCplProcess, pBuffer, MAX_PATH, MEM_RELEASE);

You have to pass flAllocationType as MEM_COMMIT|MEM_RESERVE

I did, too. And it crashed as well ... 
TCHAR* pBuffer = NULL;
pBuffer = (TCHAR*)::VirtualAllocEx(m_hCplProcess, NULL, MAX_PATH, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
if(!pBuffer) {
return;
}
I also tried to VirtualAllocEx a LVFINDINFO object to replace the local one. It crashed too but at different line. Not at FindItem call but at the line
LVFINDINFO* pInfo = NULL;
pInfo->flags = LVFI_PARTIAL | LVFI_STRING;

hmm..I missed that one...
here is the correct step..
1 . VirtualAlloc string in the remote process
2. write the string to that memory.
3. create local object of LVFINDINFO.
4. Set the flags and psz as the memory of the remote process
5. Allocate another memory in the remote process, who's size = sizeof( LVFINDINFO).
6. copy the content of the local LVFINDINFO structure to the remote memory using writeprocessmemory
7. Pass the pointer of the remote LVFINDINFO to the finditem() function

Thank you very much. It does not crash now.

I'm using VC++2005. Make a project SDI which derived from CListView. Say it is CMyListView, then add OnMouseMove, OnLbuttondown, OnLbuttonup process to CMyListView.
void CMyListView::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
if(nFlags & MK_LBUTTON)
{
AfxMessageBox(_T("enter"));
}
CListView::OnMouseMove(nFlags, point);
}
void CMyListView::OnLButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
SetCapture();
CListView::OnLButtonDown(nFlags, point);
}
void CMyListView::OnLButtonUp(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
ReleaseCapture();
CListView::OnLButtonUp(nFlags, point);
}
Then compile the project, drag and push mouse button in the view. No message box will pop up. But if it is a common CView, the message box will pop up. What's going on?
