Yes. Use GetDateFormat() and GetTimeFormat().

CAxDialogImpl::DoModal creating modeless dialog box

If you want both the date and time in the same control, you'll need to use a format string rather than one of the preset formats. See here.

Hi All,

I have designed (through project resources) and displayed a dialog box in c++ by inheriting my own class from CAxDialogImpl class and using mydlgobj.DoModal() method.

I have used this in my own created plugin for windows mail/outlook express. (dialog pops up, when menu item is clicked).

BUT problem is that DoModal is displaying a modeless dialog box not the modal one...

If I use the same procedure in my plugin for outlook, then the dialog box is modal, (as it should be).

Kindly tell me what should I do to show it as a modal dialog box in my windows mail/outlook express plugin?

Thanks!

Global Hooks and IISReset

Hello All,

I’m having problem with intercepting all calls to restart Microsoft Internet Information Services(IIS) 6.0.

I’m trying to write a Hook that will intercept all request to iisreset – i.e. if you execute iisreset.exe, I want my code in(C/C++) to suppress the restarting/stopping of IIS, do some processing work for me first and then allow iis to be restarted/stopped.

So, far my approach has been to write a system wide global HOOK dll and attached it to the inetinfo.exe process. On testing of the hook, it works for notepad.exe but does not work for inetinfo.exe. I’m using the SetWindowsHookEx function with the WH_GETMESSAGE parameter – as my understanding is that WH_GETMESSAGE should work for non-gui process as well.

My questions to you all are:

1. Is it even feasible to do what I want to do – that is to intercept all calls to iisreset?

2. If yes to the first question, then is hooking the right choice?

3. Does hooking work for Non-GUI process – as inetinfo.exe and iisreset.exe are non-gui and may not have a window procedure?

Thanks for all the help,

Jr.

Thanks for quick reply,

I have seen that function. It runs fine but i am not able to see any change to the text of the menu item.

Is there any rule to use this function, If so then please let me know.

Let me know if you have any other solution.

Thanks and Regards,

Sorry but i am not able to use it with System Tray popup menu.

Actually i have used this library to create a System Tray pop up menu.

So, Do you have any idea on this?

I am not familiar with that library. Anyway if you have the menu handle, then you can surely update it.

But I could find a BOOL SetMenuText(UINT uiCmd, LPCTSTR szText); in the documentation... Did you try that?

You can add a UI handler for the menu item

ON_UPDATE_COMMAND_UI

and do something like

void CYourClass::OnUpdateYourMenuItem(CCmdUI* pCmdUI)
{
  pCmdUI->SetText("New Menu Text");
}

Wanted to say, thanks for posting this. I had been scratching my head trying to figure out how to do this and was making it a far more difficult chore than it needed to be. This was the answer, so simple that I hadn't even considered it. worked perfectly by the way.

void function

hi to all,
need to pass a string to a void function that does not have a parameter, looks like that:

int CMyString::GetLength (void)const
{

}

in the main function, the code is follow

CMyString string1;
string1 = "Hello world!";
int nLen = string1.GetLength();// should give nLen = 11.

The class CMyString should work like the class String in this case.
Do not k now how to implement the function GetLength().
Any help will be appriciated. Thanks.

you don't know how to create a method in your own class ?

the class CMyString should hold a member variable that holds the buffer of some sort of the string.

just create a method that just do a strlen (if the buffer is a char* ) on the member variable.

something like :
class CMyString
{
//... some other stuff
char* m_internalBuffer;

int GetLength(){ return strlen(m_internalBuffer);};
}

You should (like CString, for instance does):

define a CMyString constructor accepting a const char * as argument.
overload the CMyString assignment operator (=) to accept a const char * as argument.
both of the above methods should initialize CMyString internal data member (a character buffer, for instance).
define a GetLenght method returning the strlen of the internal character buffer.

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hello,

I want to use a C++ function in order to check if a filename exists. I have already tried to use _access as well as _stat, but these functions also return true if the filename given is a fooldername instead. So how can I distinguish if it's a really a file or only a folder?
