Hello,
I would like my MDI application to start without any doc/view window. How do I do that? I've tried to override OnCreateClient in ChildFrm but that only generates a message box that says "Failed to create empty document".
Thanks...

Change your CWinApp::InitInstance function.
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
cmdInfo.m_nShellCommand=CCommandLineInfo::FileNothing;
if (!ProcessShellCommand(cmdInfo))
return FALSE;
Insert line in bold in code before ProcessShellCommand

If you mean that you dont want
any intial window that appears
in a MFC project generated by wizard.
then add this code to your applicaton.cpp file in InitInsatance function.
CXyzApp::InitInstance()
{
// CG: The following block was added by the Splash Screen component.
\
{
....
....
.....
....
...
....
....
// create main MDI Frame window
CMainFrame* pMainFrame = new CMainFrame;
if (!pMainFrame->LoadFrame(IDR_APPMENU))
return FALSE;
//->---------------no empty document window on startup------------------------
cmdInfo.m_nShellCommand = CCommandLineInfo::FileNothing;
//->--------------------------------------------------------------------------
// Dispatch commands specified on the command line
if (!ProcessShellCommand(cmdInfo))
return FALSE;
.....
.....
....

Hello, lets take a look at the STL.
We have
<br />
std::multimap<sth*, sth*> pairs;<br />
<br />
void remove(sth* s1, sth* s2)<br />
{<br />
std::multimap<sth*, sth*>::iterator i;<br />
if ((i = std::find(pairs.lower_bound(s1), pairs.upper_bound(s1), std::make_pair(s1, s2))) != pairs.end())<br />
pairs.erase(i);<br />
}<br />
Well that doesn't work. I get MANY template compile errors (really hard to read, and rearly make any sense). I'll give you a small sample:
<br />
f:\Microsoft Visual Studio .NET 2003\Vc7\include\algorithm(31): error C2784: 'bool std::operator ==(const std::vector<_Ty,_Alloc> &,const std::vector<_Ty,_Alloc> &)' : could not deduce template argument for 'const std::vector<_Ty,_Ax> &' from 'std::allocator<_Ty>::value_type'<br />
with<br />
[<br />
_Ty=std::pair<sth *const ,sth *><br />
]<br />
<br />
f:\Microsoft Visual Studio .NET 2003\Vc7\include\algorithm(31): error C2784: 'bool std::operator ==(const std::_Tree<_Traits> &,const std::_Tree<_Traits> &)' : could not deduce template argument for 'const std::_Tree<_Traits> &' from 'std::allocator<_Ty>::value_type'<br />
with<br />
[<br />
_Ty=std::pair<sth *const ,sth *><br />
]<br />
<br />
f:\Microsoft Visual Studio .NET 2003\Vc7\include\algorithm(31): error C2784: 'bool std::operator ==(const std::list<_Ty,_Alloc> &,const std::list<_Ty,_Alloc> &)' : could not deduce template argument for 'const std::list<_Ty,_Ax> &' from 'std::allocator<_Ty>::value_type'<br />
with<br />
[<br />
_Ty=std::pair<sth *const ,sth *><br />
]<br />
I think you get the idea. All the compile errors point inside std::find() where the arrow points:
<br />
template<class _InIt,<br />
class _Ty> inline<br />
_InIt find(_InIt _First, _InIt _Last, const _Ty& _Val)<br />
{
for (; _First != _Last; ++_First)<br />
----> if (*_First == _Val)<br />
break;<br />
return (_First);<br />
}<br />
I just can't understand where the problem is. Everythink looks fine to me, but obviously it isn't.
Anyother idea how am I supposed to erase a single pair from a std::multimap()? I can only find functions that erase all <key_value, mapped_value=""> pairs for a specified key but I just need to erase one of those pairs given a specified mapped_value.
That all,
Themis
PS - std::remove() also doesn't work as it relies on std::find() (at least in VS .NET 2003 implementation)

I haven't noticed anything wrong with the code tags. Are you sure your HTML is correct?

Yes I just read my message in firefox (browser I use) and then reloaded it in IE (just because of curiosity) and saw that in IE code blocks are printed red and the rest black. However in firefox everything is printed in black until a code block begins, then everything below that point prints in red, even after the code block end. Anyway that just a note.

Hi all
I am using IImnAccountManager interface for outlook express email accounts.
This interface requires imnact.h header file I downloaded this file from link
http://ftp.teklynx.fr/online//31-%20IDEAM/PPCSDK2000/Program%20Files/INCLUDE/IMNACT.h
I am writing this code
<br />
IImnAccountManager m_pImnAccountManager;
<br />
m_pImnAccountManager = NULL;<br />
<br />
HRESULT hr = CoInitialize(0);<br />
if(FAILED(hr)) <br />
{<br />
MessageBox(_T("Error CoInitialize."));<br />
<br />
}<br />
<br />
hr = CoCreateInstance(CLSID_ImnAccountManager, <br />
NULL,<br />
CLSCTX_SERVER, <br />
IID_IImnAccountManager,<br />
(LPVOID*) &m_pImnAccountManager);<br />
<br />
if(FAILED(hr)) <br />
{<br />
MessageBox(_T("Error creating OE Accounts."));<br />
<br />
}<br />
<br />
hr = m_pImnAccountManager->Init(pAdviseMigrateServer);<br />
if(FAILED(hr)) <br />
{<br />
MessageBox(_T("Error initializing OE Accounts."));<br />
m_pImnAccountManager->Release();<br />
<br />
}<br />
<br />
m_MailList.ResetContent();<br />
<br />
<br />
return TRUE;
}<br />
<br />
when I use this code then it gives errors
/*-------------------------------------------
Linking...
OutlookAccountDlg.obj : error LNK2001: unresolved external symbol _CLSID_ImnAccountManager
OutlookAccountDlg.obj : error LNK2001: unresolved external symbol _IID_IImnAccountManager
Debug/OutlookAccount.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.
OutlookAccount.exe - 3 error(s), 0 warning(s)
/*-------------------------------------------------
Though I have included imnact.h file.
Please suggest me.
Thanks

You use the tlb or idl files to extract the objects information..
You can do this by using #import<..>

After making my Visual c++ program where I use SQl server 2000 database, How can I make a package of my .exe file and database so that I can install it in others Pcs without installing the database program used.

for primitive data type, i am able to initialize them in static scope:
class x {
public:
static int var[];
};
/* We are able to have var initialize before x object being instance. */
int x::var[] = {1, 2, 3};
However, for a stl map, how i can have elements inserted into it in static scope too?
class x {
private:
static map<int, int=""> var;
};
/* The below code will generate compile error. */
/* I wish to have elements to be inserted into map before x is instanced. How I can do so? */
map<int, int=""> x::map = {
{1, 2},
{3, 4}
};
Thanks!

where did you see you could access a private member from outside the class like that ?
second point : did you have a look at how a map was working ?
<font color=blue>class</font> x {
<font color=blue>private</font>:
<font color=blue>static</font> std::map<your_key_type, your_value_type> var;
<font color=blue>public</font>:
x();
<font color=blue>void</font> InsertInMap(your_key_type k, your_value_type v);
};
x::x() {
<font color=green>
}
<font color=blue>void</font> x::InsertInMap(your_key_type k, your_value_type v) {
x::var[k] = v;
}
<font color=blue>void main</font>(<font color=blue>void</font>) {
x myX;
x.InsertInMap(1, 2);
x.InsertInMap(3, 4);
}
next time, read the docs...

Mmmh, I think you read his post a little bit too fast 
toxcct wrote:

That's the way of initializing static member variables. This is done in the cpp file in that way:
int X::MyVar = 0;
Otherwise you will have a linkking error if you don't do it.

He was asking how to fill the static map with data the same way you initiliaze the static variable. But unfortunately, I don't know if it's possible.

hum, yes, you may be right, but his post was not that clear...

yes, that's ot possible. but i still don't understand why he want to initialize like this "before making the instance"...

That's is a matter of design. Says you have a MathTeacher class, each math teacher instance is suppose to hold a "multiplication table" member variable. since you are quite sure the "multiplication table" will be same everywhere (you always get 4 when you perform 2x2), it make sense to make the multiplication table as static const scope.
so, instead of having 10000 copies of MathTeacher objects (hence, 10000 copies of "multiplication table" since each teacher is having one copy of table). by having static scope member variable, we can have 10000 copies of teachers, share one copy of math table, which we are sure it will be always constant and never changed.
hope this help.

I agree with moonen. Everyone looks daft in a new area in experts eyes.
The solution to the problem is to init the map in a constructor:
class CMy<br />
{<br />
public:<br />
CMy();<br />
private:<br />
static std::map<int, int> mymap;<br />
static CMy *p;<br />
};<br />
<br />
CMy* CMy::p = 0;<br />
CMy::CMy()<br />
{<br />
mymap[1] = 1;<br />
}

However, that need to instance the object first before the static variable can get initialized.
I have a suggestion of doing so by using lazy initialization. not so good since it is not really insert the element in static scope. however, this at least still meet my initial need: get element inserted into stl map before the class object instance created.
class x {
public:
static const map<int, int="">& GetMap {
static const map<int, int=""> m;
if(m.size() == 0) {
// Perform element insertion here.
//
}
return m;
}
};

i guess u need a 2d array,
declare char author_name[10][30];
[10] if u want multiple names to be stored.
[30] size of the names
if u want to store a single name use char auth_name[10] or char *auth_name;
V
|
|
|
|
|
u can also use char* author_name[10].only difference is that it will have addresses of multiple names.it is better than char author_name[10][30] becuse every multiple name may not be of length of 30

hi,
u need to write like this
cin>>author_name
in previous case it is declared as a pointer and the name of the array wil give u the addres location so this will work (author_name),if you go this way it will give you char ** error
check it out and tell me out .

Hi!
Now I wanna sent 4 bytes data by calling DeviceIoControl() from my directshow application to my streaming minidriver.First,I call the CreateFile() to get a device handle,and the minidriver can receive a IRP_MJ_CREATE IRP,and the CreateFile() returns nonzero.But when the app runs to DeviceIoControl(),the minidriver does not recieve any SRB.The DeviveIoControl() returns zero,and GetlastError() returns 50,which says:"The request is not supposed."
I difined my own IOCTL command in my driver and app.
What causes the error 50 or if there is any other way to send data to steaming minidriver from directshow application?
Thanks for any help!
