Hi, for some reason i can only call ON_COMMAND in my main dialog, how can i call it in a child dialog?
Any ideas would be much apreciated!

How can you call ON_COMMAND? ON_COMMAND is not a function or method AFAIK.

Hi Mark, I call it via afx_msg void OnAddNewItem(); and ON_COMMAND(ID__ADDITEM, &CItemDlg::OnAddNewItem)
Edit:
the menu item is created via CMenu and if i move ON_COMMAND(ID__ADDITEM, &CItemDlg::OnAddNewItem) to the main dialog it works fine. But i want to know why i cant call it in the child dialog
|

You aren't calling anything. You've added a method that will get called when the
window you've added it to receives a WM_COMMAND message corresponding to a
menu item or child window with the id "ID__ADDITEM".

Ok, how do i associate the menu to the dialog? The menu opens when right mouse button is pressed and so i dont care to attatch it to the Child Dialogs system menu.

The TrackPopupMenu() API/method takes a window handle/ptr to the window
that should receive the command messages.

I will try to write question shortly 
struct CEvents
{
virtual HRESULT Method1() = 0;
virtual HRESULT Method2() = 0;
virtual HRESULT Method3() = 0;
};
class A : public CEvents
{
// Implementation of VTBL methods
virtual HRESULT Method1();
virtual HRESULT Method2();
virtual HRESULT Method3();
HRESULT Some();
B *m_B;
};
HRESULT Some()
{
m_b->Initialize( (CEvents*)this );
return S_OK;
}
class B
{
CEvents *m_evs;
HRESULT Initialize( CEvents *evs );
}
HRESULT B::Initialize( CEvents *evs )
{
///////////////////// THIS IS MY QUESTION /////////////////
// This i have trouble... access violation and ect....
// But when i use not pointer to class B as member of A ( B *m_B; )
// there is no any problems - PLEASE, TOLD ME, WHY??????????????
m_evs = evs;
return S_OK;
}

Are you initialising the m_b member in the constructor of class A?

I don't see anywhere that you actually create any objects.
You have pointers declared but they are uninitialized.

i'm looking for a c++ program that will read in an ascii file and will output a csv file, is there anyway that this can be done? can anyone help me?
|
|
|
|
|
a CSV file is an ASCII file and both files are text files.
Are you only wanting to put commas between fields ?
In general, when one wants to do something like that, one will read the file in memory, parse each line ( if that is the case ) to extract the different fields (whatever is the separator criteria) and one will print out each field separated by a comma.
Do you know how to read a text file ? and write the file ?
Do you know how to parse a line of text ?

I need to parse each line based on a criteria I'm not sure how to go about it though, here's what I know:
Head data (zip file of 9.2 mbytes) A 109-slice MRI data set of a
human head. Complete slices are stored consecutively as a 256 x
256 array. Pixels consist of 2 consecutive bytes making one binary
integer. Data taken on the Siemens Magnetom and provided courtesy of
Siemens Medical Systems, Inc., Iselin, NJ.
I need the csv file so that a program called paraview can read it, I just don't know where to start.
I would appreciate any help.

It's data for a visualization of a human head, I need to parse each line according to this:

I'm trying to write a dll for the Microsoft cmak Connection manager administration kit, which we will use for a VPN connection. It's supposed to have this signature:
HRESULT WINAPI function
[IN] HWND hWndParent
[IN] HINSTANCE hinstDll
[IN] LPCSTR pszCommandLine
[IN] DWORD dwReserved
But it still uses the DllMain of my console win32 c++ dll-file. Cmak can only run DLLs synchronously. I want it to run two .exe files after each other. I start them from the DLL. It may not go on establishing the connection until both of them has executed successsfully. It has to stop after starting each .exe. That's why it has to be a DLL. It doesn't stop otherwise. No matter what function name I use in the [Pre-Connect Actions] section of the .cms-file it uses DllMain anyway.
Do you have to export the function names for automation like an ActiveX-DLL?

Hi, I used the microsoft's example to load a simple HTML file from a stream.It works fine but when I make a second call to the following method it shows a white screen.
for example :
TestPage("a.htm") --> it works
TestPage("b.htm") --> it shows a white screen have only the code.
What's wrong here ?
void CMemHTMLView::TestPage(CString filename)<br />
{<br />
<br />
Navigate2( _T("about:blank"), NULL, NULL, NULL, NULL ); <br />
<br />
LPSTREAM pStream; <br />
HRESULT hr; <br />
HGLOBAL hSource = NULL; <br />
char * source; <br />
<br />
FILE *stream;<br />
long lFileStreamSize;<br />
<br />
<br />
<br />
<br />
<br />
if ( (stream = fopen( filename, "rb" )) == NULL )<br />
{<br />
AfxMessageBox("error");<br />
return;<br />
<br />
}<br />
<br />
fseek (stream , 0 , SEEK_END);<br />
lFileStreamSize = ftell (stream);<br />
rewind (stream);<br />
<br />
<br />
source = (char*) malloc (sizeof(char)*lFileStreamSize);<br />
<br />
fread (source,sizeof( char ) ,lFileStreamSize,stream);<br />
<br />
fclose(stream);<br />
<br />
<br />
<br />
if (hSource) <br />
{ <br />
GlobalFree(hSource); <br />
} <br />
<br />
hSource = GlobalAlloc(GMEM_MOVEABLE | GMEM_SHARE | GMEM_NODISCARD, strlen(source)+1 ); <br />
<br />
void * p=GlobalLock(hSource); <br />
<br />
memcpy((char *)p, source,lFileStreamSize ); <br />
GlobalUnlock(hSource); <br />
<br />
hr = CreateStreamOnHGlobal(hSource, TRUE, &pStream); <br />
<br />
IDispatch* pHtmlDoc = NULL; <br />
IPersistStreamInit* pPersistStreamInit = NULL; <br />
<br />
pHtmlDoc = this->GetHtmlDocument(); <br />
<br />
hr = pHtmlDoc->QueryInterface( IID_IPersistStreamInit, (void**)&pPersistStreamInit ); <br />
if ( SUCCEEDED(hr) ) <br />
{ <br />
hr = pPersistStreamInit->InitNew(); <br />
if ( SUCCEEDED(hr) ) <br />
{ <br />
hr = pPersistStreamInit->Load(pStream); <br />
} <br />
pPersistStreamInit->Release(); <br />
} <br />
Refresh(); <br />
<br />
free (source);<br />
<br />
}

Loading happens asynchronously. You need to ensure that the load has finished (the load of about:blank and the load of your stream) before triggering another load. Going from memory here... but until about:blank has finished loading, GetHtmlDocument() isn't going to succeed... so at present, your routine is relying on about:config loading fast enough to allow the rest of the code to work. Which is possible and likely (but not guaranteed). Of course, the second time around, the browser will be busy loading your custom stream (which you don't seem to be releasing anywhere... bad), so it's probably not gonna finish loading about:blank until a while after your attempt to direct it to a memory stream has finished.
Realistically, you want this to happen via callbacks. Trigger the load via about:blank, then wait for the NavigateComplete2 or DocumentComplete event, then direct the browser to your stream. And, once that load is complete, free up the memory.
---- ...the wind blows over it and it is gone, and its place remembers it no more...

Yes you have absolutely right.
I changed a little the critical part of the code with the following using the NavigateComplete2 and about:blank as you recommended.
Now its working. I dont know if its a better solution from the old one, but it works.
IDispatch * pDisp = GetHtmlDocument();<br />
if (!pDisp)<br />
return;<br />
<br />
IHTMLDocument2* pDoc;<br />
if (SUCCEEDED(pDisp->QueryInterface( IID_IHTMLDocument2, (void**)&pDoc )))<br />
{<br />
CComBSTR bstrURL;<br />
CComVariant varDummy;<br />
pDoc->open(bstrURL, varDummy, varDummy, varDummy, NULL);<br />
<br />
SAFEARRAY *pSA;<br />
SAFEARRAYBOUND saBound = {1, 0};<br />
pSA = SafeArrayCreate(VT_VARIANT, 1, &saBound);<br />
<br />
VARIANT *pVar;<br />
CComBSTR bstrHTML = source;
<br />
varDummy = bstrHTML;
<br />
SafeArrayAccessData(pSA, (void**)&pVar);
pVar[0] = varDummy;
SafeArrayUnaccessData(pSA);
<br />
pDoc->write(pSA);
pDoc->close();
<br />
SafeArrayDestroy(pSA);
pDoc->Release();
<br />
}

For some magic reason I need to have /Od /Ob1 (disable optimizations, only __inline function expansion) in my release build. Don't worry about why I need to do this, I really need to do it.
Is there a way to add some magic #if in my code that will cause a compilation error if these specific compiler options are not in place?
I need this in order to prevent some dutiful developer from changing these settings 1-2 years from now and breaking the code. Unfortunately I cannot add comments in the project settings dialog (it's not the first time I needed to do so).
Thanks in advance!
