What you're doing will work for a menu attached to a dialog in a dialog based app. However, if you're using MFC's doc/view framework (SDI/MDI), you need to put the enable/disable logic in the command's UpdateUI handler.
This may be the case, but what if you need the change the menus from a different location other than in the UpdateUI handler? do you basically have to create a boolean to keep track of the state and then check it in the UpdateUI? Is this the only way?
Thanks!

Another method would be to handle the WM_INITMENUPOPUP message and enable/disable the items in that handler.

Yes, that follows the standard MVC model and would be the preferred way imho.

Hi
I am unable to open HELP from my visual studio environment. As soon as I click on any of the menuitems (contents, index etc) under HELP, the cpu shoots to 100% and it just sits like that.. I have also noticed that its allocating more and more memory, but the help window does not open at all.
MSDN was properly installed and it was working just fine before. I don't recall to have changed any of my settings.
I have already tried uninstalling/re-installing MSDN couple of times but no luck.
Any clues. Thanks

Hi,
I'm trying to find a way for an out-of-process COM server (built w/o MFC support) to control the client application's cursor (shape).
Up to this point, I've tried several different variations of LoadCursor/SetCursor; e.g.:
HCURSOR NewCursor = LoadCursor(0, IDC_WAIT);
HCURSOR OldCursor = SetCursor(NewCursor);
I've also tried to retrieve a handle to the client's window and modify the app window class' properties (for the cursor) ; e.g.:
HCURSOR NewCursor = LoadCursor(0, IDC_WAIT);
HWND hwnd = GetActiveWindow(); // returned a NULL value
DWORD OldCursor = SetClassLong(hwnd, GCL_HCURSOR, (LONG)NewCursor);
In all cases, the application builds but does not modify the cursor. I think the primary problem I'm dealing w/ here is the fact that the COM server is out-of-process.
Any suggestions?
Thanks,
Steve

Hello,
I have a strange problem with binding using the macro BEGIN_ADO_BINDING(CCustomRS).
Here is my code:
#define INITGUID
#import "C:\Program Files\Common Files\System\ADO\msado15.dll" rename_namespace("ADOCG") rename ("EOF", "EndOfFile")
using namespace ADOCG;
#include "icrsint.h"
class CSeachCustRS : public CADORecordBinding
{
BEGIN_ADO_BINDING(CSearchCustRS)
ADO_FIXED_LENGTH_ENTRY(1, adInteger, m_lCustomerID, lCustomerIDS, FALSE)
ADO_VARIABLE_LENGTH_ENTRY2(2, adVarChar, m_szCompName, sizeof(m_szCompName), lCompNameS, TRUE)
..
..
END_ADO_BINDING()
public:
LONG m_lCustomerID;
ULONG lCustomerIDS;
CHAR m_szCompName[101];
ULONG lCompNameS;
..
..
};
I am getting these errors:
syntax: missing ';' before identifier 'ADORowClass'
CSearchCustRS::ADORowClass: missing storage-class or type specifiers.
The error line is the BEGIN_ADO_BINDING(CSearchCustRS).
I have used this method successfully before, but now it will not compile...
If anybody has any experience in this area suggestions would be appriciated!
Thanks

Look at the bright side! At least it only took you 2.5 hours to figure it out.

Hello,
I want to put a string in a XML document, but
sometimes the string can have character(s) that
are not compliant with XML, for example
put this string "<test>" doen't work because it's a
tag for XML.
What is the best way to convert a string into an XML
compliant format ?
A VC ++ function ?
A MSXML function ?
Thanks for your answers !!!

if you're using CStrings, you can just use the Replace member function

If you use msxml, this will be automatically handled when you write the xml file somewhere (stream, memory, disk). (" are replaced with ", < are replaced with <, and & replaced with & ). 
How low can you go ?

Hi all,
I have several *.mak files that I have modified to fix various issues in my builds. I need to be able to import these makefile back into the projects from which they came from. I cannot find a way to do this. Is this possible? Or do I have to physically add in the changes to the project file piece by piece? I thought there would be a quick and dirty way to import the makefile back in Visual Studio. Any help is GREATLY appreciated.
Thanks!

Consider a vector of string objects.

. MFC MDI project. I have a splashscreen class which instantiates an object in the initInstance in the app class. When this function goes out of scope, the splash screen is supposed to vanish since it was a local object. Does so fine on Win2K. On win98 however, it stays there even after the UI has come up! How dO I get rid of it? Any ideas why this is happening?
Appreciate your help,

Can't you just put a close member into your splash class, and call it manually, rather than just closing in the splash's destructor and hoping the object gets deleted? (Less neat, I know, but at least that way you know exactly what's going to happen)

Okay. This might sound dumb. I didnt write the class.It has two things in it: create and onPaint, plus the constructor and destructor. What would I put in my Close() function? I dont think we can call the destructor right? Again, sorry if its an obvious question.....
Appreciate your help,

Ahh, so I guess you've currently got something like
MyClass::MyFunction()
{
CSplashScreen Splash;
..do your startup processing here..
}
The Splash object should automatically get deleted at the end of the function, when it goes out of scope, but for some reason it isn't.
Instead, try changing it to:
MyClass::MyFunction()
{
CSplashScreen* pSplash;
pSplash = new CSplashScreen;
..do your startup processing here..
delete pSplash;
}
(I.e. you now have full control over the creation and destruction of the splash screen object, which should force it to close when you want it to)

Most excellent! I truly thank you for the idea - I was getting bogged d own in what to write in a Close() function. I have to remember this idea for future use too....the power of new and delete

I havent yet ever called a C dll from within my MFC program. What is the procedure for this? Where can I find this information? The C dll might be MFC too, or maybe just plain C++.
