Can you suggest how I could proceed?
At present there is a directory and it contains pdf and txt files. Every day some person opens this directory and prints and deletes these files.
Is there an API or some generic method to move the contents this directory to an outqueue that would print. I know how to read through the directory (CFileFinder) but how do I go about submitting these files to a writer?
thanks

The easiest way would be to use ShellExecute(..., "print", ...).

How can we ensure that menu and button accelerators (&<letter>) are displayed when the dialog or application are created? Our application only shows the underlined characters after the ALT key is pressed. On the menu, the underlined characters go away, but on the dialog they stay. We'd like the underlines to always show up.
This seems to be an application-wide setting. For example, notepad and internet explorer 6 don't show the underlined characters until the ALT key is pressed. Mozilla and Outlook do. I know that this is a display setting in XP/2000, but there has to be some work-around since all the office programs have persistent underlines for the hotkeys.
Thank you,

You are right that it is a display setting ( SystemParametersInfo (SPI_GETKEYBOARDCUES, 0, &bSet, 0)).
But my copy of IE6 hides the _ until the Alt key is pressed too.
My guess is that Mozilla et al draw their own buttons and (naughtily) ignore the users preferences.
I know Office apps reimplement loads of controls each time a new version is released. Then the rest
of us who want to look "modern" play catch up!
You could also do owner draw windows, but that sounds like a lot of hard work!
Surely this is a choice your user makes, not you. If they want to the _s that much, show them how
to toggle the preference. If not, let them not see the _s, as that is how they want it!

The problem is that hiding the hotkeys is the default behavior in Windows 2000/XP (so the users don't "want it", they just don't know any better). We also have hundreds of clients who are relatively computer illiterate, and think they can't use the keyboard to access all buttons (which they can).
Since hotkeys are always visible in Office, Outlook, Mozilla, and many other applications under XP/2000, it is difficult to believe that Microsoft and others are spending the time to create new controls or owner drawn windows just to enable hotkeys to be visible ... seems more likely that there is an application setting somewhere.
Thoughts?

Microsoft seem to have a team that redesign the UI in order to keep us all on our toes playing catchup. They are always changing the GUI style.
I guess Mozilla uses open source cross platform libraries and therefore does not look for the particular windows settings.

Actually, it's all too plausible. Just look at the new menu styles, the flat look brought in by
Encarta, etc. The underlining bit is probably incidental.
There is nothing to stop your application calling SystemParameterInfo (SPI_SETKEYBOARDCUES, ...).
But this could be in your options page, with a note above it warning that it has an effect on all programs.
Or, when the program is first run, or at installation, detect the setting and ask if the user wants
to change it. And so on.
My company supplies PC with my software preinstalled. So it is the reason that PC exists. So I don't
have to be a good software citizen. But it would annoy me as an end user if software I installed
unilaterally overrode my settings. Prompting me that changing them may improve my experience is a
valid compromise...

This is a user-configured thing (i.e., what would the user think if an application came along and overruled their UI settings).
You've probably already found this, but right-click the desktop and select Properties. Click the Effects tab. Un/check the "Hide keyboard navigation indicators until I use the Alt key" checkbox.

Hi guys!
I'm looking for a quicktime expert (or C++) who tell me how I can get the header of a Quicktime movie File. I know that The movie header is inside a QTAtom named MovieDirectory but I don't know how access to that atom starting from the movie File.
I'm using the QT6SDK. There is a GetMoviePropertyAtom function but I didn't understand what this function really do.
Thanks a lot for your help (if you can....).

hi gang!
am wondering if win32 memory mapping using "CreateFileMapping" ,"MapViewOfFile" ,"OpenFileMapping" ...
is thread safe or not ?
i mapped a queue in the file mapping section and i must know if this section is syncronized by default or i've to sync it manually .
please give me u'r clues .
many thanks in advance !

Short answer is no.
Its not any more thread safe than un-file-mapped memory. The only real difference is that
your changes are occasionally flushed to a file, and that it can be reflected in memory
in another process.
On another note, if you are using the mapped memory between processes, then any variables
in it that are pointers are unlikely to be valid in the other process. So a queue may
be dangerous, depending on how you've implemented it.
You can get around the synchronisation problems by using named synch objects in both processes.

Dear Friends,
Sometime my application gives an error and an abnormal error dialog box gets created and immediately after that my application closes. Also some time my application hungs-up.
I am not able to find out the actual error because usually it never happens but sometime it happens and that is why it is not easy to track errors.
1. Thus please tell me how to create a log file to track of each operation.
2. Also I would like to track few errors like access violation, abnormal error window generation.
As I am also unable to get the exact error so I cannot give any more idea abt errors so it may help if I can create a log file or can track few errors as specified.
Thus please help me to find out the solution.
Also please write to me whether I can make my program to generate a particular error to check whether my preventive measures are working properly.
I am new to VC++ and at present I am unable to find any solution of it. Although I find a function say GetLastError(), but how to use it, to a particular error, I am not getting........I think WM_ENABLE message may also help me in case of hung-up but how to add this message to class wizard?
Thus please help me to find the solution...
Thanking You in advance.

Hi guys,
I ve got a question, a stupid question maybe...
I m making a DLL, with oviously heaps of functions in it. I would like to have a static variable (something that could be modified my some functions). I was wondering if there is nothing dodgy in creating a static variable in a DLL. Since, I dunno how and when exactly the DLL is loaded and unloaded. Is it reloaded each time a function gets called? It s a bit fuzzy to me.
Maybe there is nothing special in this but I just wanted to be sure..
Thank u 4 ur help...

There are ways a DLL can be loaded.
1/ Implicitly. This is the usual way. It happens if you link to the DLL when you are creating
your EXE. When the DLL is loaded, the DllMain function is called, and static variables in
that module (DLL) are initialed. This happens once for each process. See DllMain for
more detail.
2/ Explicitly. This happens at runtime, by the SDK function LoadLibrary.
There are articles on codeproject about DLLs for beginners. I would recommend looking there.

Hi,
Does anyone know what the most efficient method is for copying a large list or vector of data (about 25000 elements)?
cheers,
|
|
|
|
|
I guess that depends on what you mean by copying. If you're talking about duplicating the elements in other list/vector of the same type, then for lists I don't think you can do better than:
std::list<int> l1;
...
std::list<int> l2;
l2=l1; As for vectors, you can be a little smarter:
std::vector<int> v1;
...
std::vector<int> v2;
v2.reserve(v1.size());
v2=v1; Hope this helps.

cheers Joaquín for replying. Just so I've understood correctly all I need to do is
list1 = list2
and then list1 will have copies of all of the elements in list2 and then any changes I do in either list will not be reflected in the other list? If so this is a lot easier than the method I implemented!!! (I went through the list in a while loop and then copied each element, not very efficient)
thanks,
Andy

I don't want to dissapoint you, but basically the internals of list1 = list2 do the same kind of loop that you were using, so don't expect any performance improvement

It works fine when I compile under VC 6.0 but when I convert the project to a VC .NET "solution", the following line will return a NULL pointer:
Code:
CWnd* pWnd = GetParent()->GetDlgItem(edt1);
Any helps? Thanks.

Break the question into steps.
Does GetParent () actually return the window
you are expecting?
Is edt1 still valid? Did you assign a number to
it that no longer matches the ID of the control you are
trying to access?
Is that control actually being created? You can check this
using spy++ etc to see if it (a) exists, and (b) has the
right ID.
Etc.

Hi All,
I am new in vc++.
I would like to send data from one dialog box to one property page.
My question is:-
A property sheet contains two-page (Cpage1 and Cpage 2).
Page1 contains one command button(btnClick) and one text box(nText1).When I press btnClcik , it calls a dialog box(Cdlg) and dialog box contains one text box(nText2) and on Command Button(btnOK).
NOW, I would like to enter integer type value in the text box(ntext2) and then press the btnOK of dialog box.
Then entered value should be shown in the textbox(nText1) of Page1(Cpage).
How to do this.
Regards
Rajesh,

The Cdlg class should have an int member variable. After the call to DoModal(), simply access this member variable. Something like:
class Cdlg : public CDialog
{
public:
int var;
};
page1:onbtnclick()
{
Cdlg dlg;
dlg.DoModal();
int var = dlg.var;
}
