Hi,

How to make command UI fuctions like;
pCmdUI->SetText,
pCmdUI->Enable,
pCmdUI->SetCheck to work when we have a menu in dialog?

Currently it works for menus in SDI/MDI's but not in dialogs Confused | :confused:

Thanks Jose.

I also found a easy way to do this something as below,

// Get the popup menu which contains the "Lock" menu item.
CMenu* mmenu = GetMenu();
CMenu* submenu = mmenu->GetSubMenu(2);
submenu->CheckMenuItem(ID_LOCK, (m_bLock)?MF_CHECKED : MF_UNCHECKED | MF_BYCOMMAND);

Poke tongue | ;-P

Well, that's a different approach. It means that whenever (and wherever) you change m_bLock, you have to get to the menu item and change it.

The other approach goes the other way, whenever the menu needs to be shown (and only then), you get the chance to alter its state (enable, check, text, etc.). Besides, it's a general mechanism you can use for any menu item.

But I agree that, if that's the only menu item you need to change and if m_bLock is only changed in a single place, your method is simpler Smile | :)

Use ShellExecuteEx to find out the handle to the process and then use GetProcessId to find out the corresponding process id.

Don't try it, just do it! Wink | ;-)

Hi,

I am using ADSI api and want to extract Net BIOS name from DNS using C++.
I got following sample from MSDN. But this sample is not compiling. I got following compilation error:
error C2065: 'IADsNameTranslate' : undeclared identifier

I have Included "activeds.h" and "Iads.h" in the header files but still I am not able to get the desired result.

If someone has worked on it then please sent me the working code.

#include "activeds.h"
#include "Iads.h"

int wmain( int argc, wchar_t *argv[] )
{
IADsNameTranslate *pNto;
HRESULT hr;
hr = CoCreateInstance(CLSID_NameTranslate,
NULL,
CLSCTX_INPROC_SERVER,
IID_IADsNameTranslate,
(void**)&pNto);
if(FAILED(hr)) { exit 1;}

hr = pNto->InitEx(ADS_NAME_INITTYPE_SERVER,
CComBSTR("aDsServer"),
CComBSTR("aUser"),
CComBSTR("userDomain"),
CComBSTR("passwd"));
if (FAILED(hr)) { exit 1;}

hr =pNto->Set(ADS_NAME_TYPE_1779,
CComBSTR("cn=jeffsmith,cn=users,dc=Fabrikam,dc=com"));
if(FAILED(hr)) {exit 1;}

BSTR bstr;
hr = pNto->Get(ADS_NAME_TYPE_NT4, &bstr);
printf("Translation: %S\n", bstr);

SysFreeString(bstr);
pNto->Release();
}

Which compiler are you using ?
You might find that is isn't valid for Visual C++ 6.0, just for the .NET versions.

Take more time debuging your program and arrange everything so u can read it better and understand it.

Anyway enjoy here is ur new code and it is working.

#include <iostream.h>
#include <string.h>
#include <assert.h>

class weather

void setall(int,int,int,int,int,char*);
int get_day();
int get_month();
int get_year();
int get_temp(int);
int get_humid();
void print();
void get_condition();
};

weather::weather(int x,int y,int z,int t,int h,char *k)

}

weather::~weather()

MFC splitter window view linkage

Mister Transistor14-Jul-05 0:22

14-Jul-05 0:22

Hi,
I'm building an MFC app (not everyone has moved to .NET yet, in fact I have decided to skip .NET and wait for the next framework, due any time now)that has a splitter window with two main panes, left and right. In each pane I have a tab control. The left tab control has a tree control in each tab. The right tab control will have different controls in each tab, depending upon the selection in the left tab control's selected tree and item.

That's all fairly specific, but my question is quite general. What is the best way to cause events in one pane of a splitter (in the case selecting a treeitem) to make things happen in another pane. In a more simple example, how would events in the left view cause changes to the right view?

I ask this because normally views do not know about each other, only about their parent frame. What's the most elegant way to link the views? (NB, I'm not asking what are the tree notification events, I know those).

I ask this because normally views do not know about each other, only about their parent frame. What's the most elegant way to link the views? (NB, I'm not asking what are the tree notification events, I know those).

Both views are linked to the same CDocument, right? I'd follow the same approach as for document data changes in general.

I'd add the following to the document:

1. some member to represent the shared state (i.e.: 'selected item')
2. a member function to get the shared state
3. a member function to alter the shared state
4. an enum with identifiers to be used in UpdateAllViews notifications, including an identifier for "shared state changed".

Then, the view that changes the selected item simply calls the method in 3, which is implemented as follows:

////////////////////////////////////////
// in your document header file:

class YourDocument : public CDocument
{
   // normal stuff
   [...]

public:
   enum UpdateHints {ANY_CHANGE, SELECTED_ITEM_CHANGED, ...};
   void YourDocument::ChangeSelectedItem(ItemIdentifier item, CView* pRequestingView = NULL);
};

////////////////////////////////////////
// in your document implementafion file:

void YourDocument::ChangeSelectedItem(ItemIdentifier item, CView* pRequestingView /*= NULL*/)
{
   m_itSelected = item;
   UpdateAllViews(pRequestingView, SELECTED_ITEM_CHANGED, NULL);
}

The OnUpdate implementation for the right view can do something like:

void RightView::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint)
{
   switch (lHint)
   {
      default:
         Invalidate();
         break;
 
      case YourDocument::SELECTED_ITEM_CHANGED:
         OnSelectedItemChanged();
         break;
 
      // Other hints
      [...]
   }
}

void RightView::OnSelectedItemChanged()
{
   // Get selected item from document
   [...]
 
   // Update controls in view
   [...]
}

Hope that helps,

Bitmap Resource Loading

13-Jul-05 22:46

Hi there ! I want to load a bitmap from inside my application in order to display it on a dialog box !
In "resource.h" file i wrote:
"#define IDB_BITMAP_SPLASH 500"
In "resource.rc" file i wrote:
"IDB_BITMAP_SPLASH BITMAP "SPLASH.BMP", where SPLASH.BMP is the name of my bitmap file.
In "main.cpp" file i wrote:
"HBITMAP hBitmap=(HBITMAP)LoadBitmap(hInst,MAKEINTRESOURCE(IDB_BITMAP_SPLASH));", where "hInst" is my application's instance handle.
The problem is that this function is returning NULL. I've also tried with "LoadImage()" and "LoadResource()" functions. None of them work ! I've tried instead of MAKEINTRESOURCE to simply write "Splash.bmp" as if i were loading it directly from the file. Does not work !
Can anyone help me Confused | :confused:

? I'm using Windows 2000 SP4 and i'm not writing this in MFC, but in simple Win32API.
ThankYou Smile | :)
