To change the color of a button, I believe you need to override the OnCtlColor() method of the dialog class.

hello everyone..
this is my first post in this forum and actually it's a question about DLL's:
I made a *.cpp file with the following
#include <afx.h><br />
#include <Mmsystem.h><br />
<br />
LPCSTR _stdcall OpenSound (LPCSTR lpfile){<br />
CString str = lpfile;<br />
MCIERROR dwRet;<br />
<br />
str = "open \"" + str + "\" alias jack";<br />
<br />
dwRet = mciSendString(str,NULL,0,NULL);<br />
if (dwRet)<br />
MessageBox(NULL,"Fail to open","Hello!",0);<br />
else<br />
if (mciSendString("close all",NULL,0,NULL))<br />
MessageBox(NULL,"Fail to close","Hello!",0);<br />
<br />
<br />
return lpfile;<br />
}
and ofcourse I made a *.def file for it..
the problem is that the final DLL is TOO big ((80.0 kb in Release and 1.23 mb in Debug))
I made a dll in vb which contains a lot of functions and the size of it was about 60.0 kb..
so is there a way to minimize the DLL made by c++..

80kb doesn't sound too large to me.
What version of CString are you using?
Is it the MFC or ATL version? Are you statically linking or dynaminc link ATL/MFC
What kind of compiler optimisation settings are you using?

I'm using the MFC and I don't know how to know if it's statically or dynamically!!
also I don't know about the optimisation thing..
actually I'm a very newb to these stuff..

This is a very common misconception among new Windows programmers. I suggest you read these three articles:

Via: SIP/2.0/UDP 10.20.30.40:5060;branch=z9hG4bKDB2DC20E6BEB4E0FB3C0F299D0F3114D

My code is as follows
May be i have mistake in it.
str gives nothing;
void CCloseDlg::OnDropFiles(HDROP hDropInfo)
{
AfxMessageBox ("Darg n drop");
LPTSTR str;
UINT n;
DragQueryFile( hDropInfo, 0xffffffff , str, n);
AfxMessageBox(str);
CDialog::OnDropFiles(hDropInfo);
}
plz make correction... i want to get whole path and file name
thanx
Regards.

You have to allocate the buffer for the return value, and also use a correct file index:
TCHAR str[MAX_PATH];
UINT n = MAX_PATH;
UINT nFileCount = DragQueryFile( hDropInfo, 0xffffffff , str, n);
for (int fileIndex = 0; fileIndex < nFileCount; ++fileIndex)
{
DragQueryFile( hDropInfo, fileIndex , str, n);
AfxMessageBox(str);
}
|
|
|
|
|
Indeed you have errors
MSDN:
lpszFile
Address of a buffer to receive the file name of a dropped file when the function returns. This file name is a null-terminated string. If this parameter is NULL, DragQueryFile returns the required size, in characters, of the buffer.
You dont have a buffer, u just have an address
Anyway check this class[^]

I need to group variables into different segments.
At runtime I have to get the absolute start-adresses and sizes of the sections (in dll and/or exe).
I know using dumbbin.exe (and the map-file) will give me some information.
keywords: data_seg, bss_seg, dumbbin

Dear Programmers,
I am working on an MFC/Dialog based project. I defined a function pointer in a class's header file as a static like below;
...
typedef BOOL (WINAPI *blTagHCWDOGEnable)(DWORD IN_dwSecTime);
static blTagHCWDOGEnable blHCWDOGEnable;
...
Then I initialised this function pointer from a dll with ordinary function (LoadLibrary(...) , GetProcAddress(...))
Everything is working OK in this class. I am able to use this function but when I try to use this function from another class I am encountering errors. As if something modifying content of function pointer and it is equaling to NULL.
What may cause this?
Thanks and best regards

The static keyword. Each file that uses your header file will get its own copy of the variable, so if you set it from one file, other files won't see the change.
Change static to extern and define the variable in one of the .cpp files without the extern keyword. That should help it to work.

I have not applied yet but I am sure it will work.
Thanks for your clear explanation.

or you can use
typedef VOID (CALLBACK* PROCEDURE)(VOID);//or any parameter
PROCEDURE procedure;
dllhinst=LoadLibrary("x");
if (dllhinst!=NULL)
{
procedure=(PROCEDURE)GetProcAddress(dllhinst, "Function");
}
I can assure this will work very well

Hi, I am in the early stages of generating an app that runs from the system tray icon (never used this before). However, I am getting a compile error on the message map entry for WM_TRAY_MESSAGE (which is #defined earlier as WM_USER+1) :-
IMPLEMENT_DYNCREATE(CReminderView, CView)
BEGIN_MESSAGE_MAP(CReminderView, CView)
//{{AFX_MSG_MAP(CReminderView)
ON_MESSAGE(WM_TRAY_MESSAGE ,OnTrayNotify)
//}}AFX_MSG_MAP
// Standard printing commands
ON_COMMAND(ID_FILE_PRINT_DIRECT, CView::OnFilePrint)
ON_COMMAND(ID_FILE_PRINT_PREVIEW, CView::OnFilePrintPreview)
END_MESSAGE_MAP()
The mapped function (in this class) is:-
afx_msg void CReminderView::OnTrayNotify(WPARAM wParam, LPARAM lParam)
{
....
}
The error I get is :-
error C2642: cast to pointer to member must be from related pointer to member
I don't understand the relevence of this error to the statement ON_MESSAGE(WM_TRAY_MESSAGE ,OnTrayNotify)
as the first parameter is a constant and the second is to a pointer to function contained
within this class. Where is the cast ?
Can someone get me back on the "straight and narrow" please ? (knowing me, it's probably something REALLY simple, but I can't see it !)

The problem is that messages handled with ON_MESSAGE() (including OnTrayNotify()) must return an LRESULT, not void. The cast is inside the ON_MESSAGE() macro. Look in the source for the macro to see how it works.

Hello,
I need to design a dialogue that its shape is changed with the user interface. It is very similar to a tabbed dialogue box but the active propertysheet would be selected by the selection on a tree control. I remember from old times that VB has a container control that I can put several control on it and then when I set the visibility of the container to true, all of my control on that specific container become visible and vice versa. Is there any way that I can do this in VC6? I tried to do this by using CPropertySheet without any success. Any help of code sample appreciated.
Best regards
Dialogue container
