Hello,

I know there is function that escapes an URL (for example transforms "bla bla" to "bla%20bla")...

What was its name?

Confused | :confused:

Dominik

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

UrlCanonicalize

Takes a URL string and converts it into canonical form.

And there was me thinking it mean promoting to sub-bishop...

Hmm, I couldn't find that function... it's in the shlwapi.lib file, but I don't have any header file that contains the function declaration...

Perhaps I need latest platform sdk...

Thanks for your reply!

Hi,

I was wondering if someone could help me disable a menu option.

Thank you for your help.

If you're using MFC, look up EnableMenuItem in the CMenu class documentation.
If you're not using MFC, just look up EnableMenuItem.

Hi Jason,

I don't have MSDN installed on this computer, I only remember off the top of my head its something like :
EnableMenuItem((i think its the menuID?), Flags);

Can you or someone shed some light to get this done with MFC?

Thank you for your help!

You can find it online at msdn.microsoft.com[^].
It is the one most valuable resource you need as a programmer. BTW - Your compiler came with a copy of MSDN.

BOOL EnableMenuItem(
HMENU hMenu, // handle to menu
UINT uIDEnableItem, // menu item to update
UINT uEnable // options
);

or

// MFC CMenu
UINT EnableMenuItem(
UINT nIDEnableItem,
UINT nEnable
);

I have only been programming for a month, so please be patient.

right now i am using the code i found on the msdn.microsoft.com site

CMenu* mmenu = GetMenu();<br />
CMenu* submenu = mmenu->GetSubMenu(0);<br />
submenu->EnableMenuItem(ID_FILE_NEW, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);

I get the error that GetMenu doesn't take 0 parameters?
Can someone tell me whats wrong. I used similar code if not the same, to get a couple other menu options checked/unchecked and it worked fine. Don't understand why it doesn't work.

Oh yeah, I have no idea why msdn is not installed on this computer? its not my own.

You are mixing CWnd::GetMenu/CWindow::GetMenu and ::GetMenu

Win API: HMENU GetMenu( HWND hWnd );

From your mainframe class try calling GetMenu()...

I am calling this from my main class...

I don't get it. I have almost the same exact code right beneath it and it works. (this is the code that checks the menu options)

Thanks for helping

One possible reason is that windows calls PreTranslateMessage() before updating the control.

multile doModal calls from one InitInstance() fails

ohadp3-Sep-03 1:35

3-Sep-03 1:35

I have a program that needs to open and close and open and close several modal dialgos one after the other.

My first modal dialog goes great, but when I call the second one's doModal, it immediately closes.

I bet this is somehow related to a WM_QUIT remaining in the message-queue or something like that, but I can't really put my finger on it.

Can someone help ?

Thanks

Some more investigation brough up this solution:

After the first (and any other doModal()), do:

while (PumpMessage()) {};
AfxGetThreadState()->m_nDisablePumpCount--;

this will eat all messages up to and including the WM_QUIT (which increases m_nDisablePumpCount), we then ammend this counter and continue. (This counter is what causes the abrupt closure of any window to attempt and open.

Is there a cleaner solution (except for overriding PumpMessage and handling things different from inside there) ?

One down side to storing data in plain ASCII is that it's readable using a simple text editor like Notepad.

Another limitation is that you're limited to the ASCII set of characters, which means if you want to store binary data, you'll need to convert it to ASCII (which causes a 2x increase in size) before storing it.

If you're looking for a general article on serializing data, you might find this set[^] of articles helpful.

Check out CStdioFile, it will do what you want.

Also you can use regular C++ iostreams (e.g., ifstream and ofstream) to be more "standard" or if you aren't using MFC. MSDN has docs for all of these.
