At the top of the source file, where you want to use cout:
#include <iostream.h>
Regards, mYkel

|
|
need to put #include "stdio.h" at head
|
|
|
|
|
Which does nothing for cout. stdio.h is for printf and related functions.

#include <iostream>
using std::cout; <font color=green> Another poster suggested <iostream.h>, but that's obsolete, non-portable, and incompatible with the standard. Don't use it for new code.

I need to make some utility wich would be able to get basic information
about quick time (.mov) and real video movie files,
like length of movie in seconds, and whether it also contains audio track.
Does anybody know about some free lightwight library for this ?
Or some documents how to do this ?
Thanks

Actually, I think it's the linker.

Hi there,
I'm experiencing problems disabling/graying menu items in the default menu added to an MFC application.
The following code to to check an item works but when I try to disable/gray a menu item (also shown below) the item is still enabled and not grayed (it doesn't change state):
<br />
CMenu *pMenu = GetMenu();<br />
pMenu->GetSubMenu(0)->CheckMenuItem(ID_FILE_NEW, MF_CHECKED);<br />
<br />
pMenu->GetSubMenu(0)->EnableMenuItem(ID_FILE_NEW, MF_GRAYED);
EnableMenuItem() returns 0 which, according to MSDN, means the previous state was MF_ENABLED.
Do any of you guys have an idea what might be causing this problem?
Thanks in advance!

Your code is working correctly, but the state of the menu item is being changed back to enabled by how MFC works. When a menu is about to be displayed, MFC will fire of a ON_UPDATE_COMMAND_UI handler for every item in the menu. If you handle this and disable the specific menu item in that handler, it will work OK. If you do not handle it, MFC will enable the menu item by default if a ON_COMMAND handler exists in the call tree for that item (i.e app/mainframe, doc or view).
So, you really need to enable/gray the item in the ON_UPDATE_COMMAND_UI handler for that specific menu item

Thanks for your reply. It makes sense 
Anyways, I saw the MSDN reference for the "CCmdUI* pCmdUI" parameter of the ON_UPDATE_COMMAND_UI handler function which looks like this:
<br />
void CFileDoc::OnUpdateFileSave(CCmdUI* pCmdUI) <br />
{<br />
pCmdUI->Enable(m_fModified);<br />
}<br />
In that code it looks like you need to keep track of whether to enable or disable the button.
Is that really so? I mean, would I really have to create new variables for each element I would like to be able to enable/disable later on to hold the current state?

hy, im wondering, what in your opinion is best. or what are the differences?
i tryed to do something with the microsoft installer (the one from the studio.net) but it doesent work really. i cant configure launch conditions (i tryed 2hours..) and i cant run any c++ code or a .exe file BEFORE i run the setup. ist this possible at all with installer?
with installshield this is no problem!

The deployment project type in Visual Studio .NET is a pretty simple wrapper around the core Windows Installer technology. If you don't need anything complicated, it's great.
Otherwise, look at some other tool that wraps Windows Installer, such as a newer version of InstallShield or Wise for Windows Installer[^]. It's the same install engine, in the end, but these tools give you far more power than the VS.NET deployment project does. This power is at the expense of simplicity.

Hi all..
How do i insert a slider control in the mainframe of an mfc application.
Bye
|
|
|
|

Put something like:
m_wndSlider.Create(TBS_HORZ | WS_VISIBLE, CRect(5, 100, 500, 150), this, 1234); in the OnCreate() method, where m_wndSlider is a CSliderCtrl object.

thank you,

SetSysColors() is the easiest way (but it will change the colors of all the dialogs on your system).
Otherwise, override CDialog::OnPaint() to paint the dialog background, and handle WM_CTLCOLOR for all the child controls.

You'll need to override the OnCtlColor() virtual function of the dialog class and handle the returned brush color.
You can then change the background color of the dialog, edit controls, static text, except the Button controls.
Search for Q117778 on the MSDN website for further examples.
