In the MSDN, it says below:
lpszIcon
Identifies an icon resource. This parameter can be either a null-terminated string or an integer resource identifier passed to the MAKEINTRESOURCE macro.
To load one of the standard system-defined icons, set the hInstance member to NULL and set lpszIcon to one of the values listed with the LoadIcon function.
This member is ignored if the dwStyle member does not specify the MB_USERICON flag.
MSGBOXPARAMS msgparam = {0};
msgparam.cbSize = sizeof(MSGBOXPARAMS);
msgparam.hwndOwner = NULL;
msgparam.lpszText = _T("text");
msgparam.lpszCaption = _T("caption");
msgparam.dwStyle = MB_USERICON | MB_OK;
msgparam.hInstance = NULL;
msgparam.lpszIcon = ::LoadIcon(NULL, IDI_WINLOGO); <font color="blue">I want to use as the MSDN says.Actually I know it will compile error.</font>
::MessageBoxIndirect(&msgparam);
<pre>

 What is the problem ? What is your question in fact ?
Di you have a compilation error ? If yes, why don't you simply put the exact error message so we can try to help you ?
|
|
|
|
|
//msgparam.lpszIcon = ::LoadIcon(NULL, IDI_WINLOGO);
msgparam.lpszIcon = MAKEINTRESOURCE(IDI_WINLOGO);
The MSDN has fooled me, or I misunderstand the MSDN words, I should just use MAKEINTRESOURCE, not using ::LoadIcon.

msgparam.lpszIcon = (LPCTSTR)::LoadIcon(NULL, IDI_WINLOGO);

set lpszIcon to one of the values listed with the LoadIcon function means:
lpszIcon can be one of these value:
IDI_APPLICATION
IDI_ASTERISK
IDI_ERROR
IDI_EXCLAMATION
IDI_HAND
IDI_INFORMATION
IDI_QUESTION
IDI_WARNING
IDI_WINLOGO
so you can use them directly.
msgparam.lpszIcon = IDI_WINLOGO;

Hello,
I made a dll that has a bunch of functions called from a console application. One of them creates a CFrameWnd window. Inside the function that creates my CFrameWnd, I can create a CToolBar object. However I now want the user of the dll (the creator of the console application) to be able to attach a customized CToolBar object to that window (instead of the default CToolBar object that I created during window creation inside the dll). So I thought I simply create the customized CToolBar object in the client application (console application) in the same way I did in the dll function. That however does not seem to work: in release mode the toolbar appears, but doesn't have any bitmap, in debug mode, I get debug assertion errors because of unexisting resource or instance handles.
Following few lines in my console application are impossible to execute without assertion errors in debug mode:
CToolBar* toolBar=new CToolBar();
toolBar->CreateEx((CFrameWnd*)dllFunctionGetFrameWnd(),TBSTYLE_FLAT,WS_CHILD|WS_VISIBLE|CBRS_SIZE_DYNAMIC|CBRS_TOP|WS_CLIPCHILDREN|WS_CLIPSIBLINGS);
toolBar->LoadToolBar(IDR_TOOLBAR1);
toolBar->SetWindowText("Toolbar");
toolBar->EnableDocking(CBRS_ALIGN_TOP);
Anyone knows a workaround? Or can anyone propose an alternative solution to my problem?

You need to look at the assertions and the code where they occur.
You should see what's going wrong.
You need to make sure you're making the right kind of DLL if
you're using MFC in a DLL. All the info you need to do this
can be found here: Kinds ofDLLs[^]

Hai all
Just i want to develop a apllication that track the amount of data transferred while I am on net, both sent and recieved. It will also keep monthly records on each time log-in basis, so that I can get my usage data.
If You have any Ideas pleas share with me
Thanks & Regards

Excel.Application COM may be solve your problem.

Try using the *.csv fileformat. (comma separated values). It is still a text file but can very easily be generated and imported into excel

My goal:
when user click on the 'close' red check button on the right top most dialog, I want to hide the main dialog of the app, show an icon in the tray(these codes work fine, not showing).
My codes are below, It exits the app anyway.
BOOL CMyVIPTestDlg::PreTranslateMessage(MSG* pMsgIn)
{
if (pMsgIn->message == WM_SYSCOMMAND)
{
if (pMsgIn->wParam == SC_CLOSE)
{
this->ShowWindow(FALSE);
return TRUE;
}
}
BOOL bRet = CDialog::PreTranslateMessage(pMsgIn);
return bRet;
}
|
|
|
|
|
If you're using MFC, why not respond to the message the MFC way?
ON_WM_SYSCOMMAND()
void CMyVIPTestDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
if (nID == SC_CLOSE)
{
ShowWindow(SW_HIDE);
return;
}
CMyDialog::OnSysCommand(nID, lParam);
}
That works fine for me - I just tested it.
It's always curious to me how often the PreTranslateMessage() method is misused.

Thanks for your reply.
Acctually, I think the PreTranslateMessage is the most misusable method.
When don't know where to handle the message, the first place to place the code is the PreTranslateMessage.

That's why it's a good idea to know how to use the documentation.
All the MFC message map macros for WM_ window messages start with
"ON_WM_". If the message map macro doesn't exist for a given message,
there's always ON_MESSAGE, which will handle any message.

Hi,
I was wondering if someone could clear this up for me.
Consider the below statement:
<br />
#define randomise(i) rand() % (i)<br />
The way I see this, both randomise and rand are functions.
But a search online made me think randomise could also be deemed a macro.
Is randomise, in computer science terms, a function or a macro (or both)?
Cheers,
|

randomize is a macro.
rand is a function in the CRT library, but in the code you've shown,
it's just a token used during expansion of the randomize macro by the
pre-processor.
The VC/VC++ docs call your randomize macro a "function-like macro".
That's my take on it

Hi Mark,
Thanks for your reply.
Looking at the definition for a function:
"In computer science, a subroutine (function, method, procedure, or subprogram) is a portion of code within a larger program, which performs a specific task and can be relatively independent of the remaining code"
Could I argue that by calling randomise() it's performing a "specific task"?
The difference between a macro and a function seems to be vague.
Thanks,

Of course you could, but you'd be wrong LOL - just kidding
The thing is, you can't "call" randomize. The compiler pre=processor replaces
occurrences of randomize(n) to the token (macro expansion), so the actual code
called at runtime is rand() % (i).
Note that more parenthesis should probably be used here...
#define randomize(i) (rand() % i)
... just in case you use it in a complex expression...

Maybe for computer science, but not for the compiler (and developer) point of view.

As far as the compiler is concerned, randomise() doesn't even exist.

Yeah I understand what you guys are saying now.
The preprocessor goes through and replaces randomise() with the defined macro before the code is compiled into a binary.

I want to write a small service program to hook the system events such as the system is being to shutdown. I want to intercept the user's select before the OS. For example, the user select to shutdown the system, then my service intercept the message first and check if the specified job has been done or not, if not, do it, otherwise left the message to the system directly. How to resolve it?
