Have you called GetLastError() when EndPage() returns a negative value? The code returned by GetLastError() will probably give you a clue as to what is going on.
You may be right

Hi,
My CListCtrl has 2 columns of data, but I don't want to show the column headers, just the data.
Is this possible?
TIA
Tony

If it is not conditionally visible, you can set a empty string for that column, though simple but fits your requirement.

Problem solved,
I should play about with the Dialog Editor more and see the option to show header control..........

Can you share the information?
|
|
|
|
|
Sure,
In the VS Resource Editor, one of the properties of the CListCtrl that you can set is "No Column Header".
I set this TRUE and my column header disappeared, as required.

I may be wrong, but there is probably an API call to do this as well. You likely need to use GetWindowLong() to obtain the style settings, then remove the bit that sets "No Column Header" and findally call SetWindowLong() with the new style settings.

You're attempting to use the framework in a way for which it wasn't intended. While you may in the end get the results you're looking for, in all likelihood you won't; you will probably keep running into issues where the framework is doing something that's incompatible with your scheme. The reason is simple - like I said, you're trying to use the framework in a way for which it wasn't intended.
Typically, when you run into a situation like this, your code will get uglier and uglier as you try to force the framework to your purpose. The ugly code is trying to tell you something - you need to rethink your approach to the problem. Why on earth do you want child windows all over the place but no mainframe? (Don't answer - I'm really not interested in debating the wisdom of your scheme.)
The bottom line is this. If you're going to use MFC, you're going to be a lot better off if you go with the flow and stop trying to force the framework to do something it wasn't designed for. You would be better off finding a framework that supports the architecture you're trying to implement.

In VC2010, there's a c++ app wizard that lets you create multiple top level windows - maybe that's what you want?

ps, In VC6, I know of no whay to do what you're asking, especially if you want to show and then hide the CMainFrame.

Hi I just came across a function like
void (int a, int b,...)
{
//code
}
I assumed it as variable argument..But am I correct? If yes, how does it work exactly?...

What about documentation [^], [^]?

Your assumption is correct; see here[^] for documentation on how to implement this feature.

Hi to All,
I want to create a sine-wave like the one in (Windows Task Manager->performance Bar)..which should be moving depending upon some input.....
Please give me some hints
-----------------------------

|
|

|

Could you be a bit more explicit ? What do you mean exactly by creating a sine wave ?
Do you want to display some signal on the screen ? Are you looking for a kind of chart control ? If yes, take a look at my sig.

|
|
|
Thanks for the reply
I know my questions is not specific.
I am just doing this to just to learn.I am a VC++ learner. when i was looking at the windows task manager performance tab, it strike my head to create something like that, ...since then i am breaking my head....I guess you can assume just drawing a signal....

If you want to learn how to do something like that, the easiest way is to look at the code of another example[^]

thanks
I will go through that and if u dont mind, i will get back to you for further doubts..

What exactly do you mean by "call php script"? As far as i know, java-script and vb-script are usually client-side scripts while PHP is server-side. Do you mean you have the php script on a web server and you want to execute it and get the result thorough http (to which i might have an answer) or you want to execute a php script "within" your own application, something like including a php interpreter inside your executable or such (to which i don't have any answer to)?

yes i am actually looking for the second logic of yours.

Hmm, you got me there sadly, look around the Zend[^] site, maybe they have something you can use...

Sorry if this is kind-of long... the first few lines basically contain the question, the rest clarify what I really need. Feel free to read as much as you have time for.
Does anybody know a good tutorial on programming applications with multiple entry points in C++?
I am designing an application in MSVC 2008 Express that will interface with an AS/400 system and process scripts to either feed data, extract data by reading the screen, or do custom tasks. I was planning that it could be a stand-alone program where the user loads a script and it runs, or it could be a liason between Excel and the AS/400 via COM. I was also thinking that double-clicking a file (say, on the desktop or in Windows Explorer) could add the file to the process queue, and that if the program is open I could also add a file to the queue by putting the file into a particular directory. (I think I have that part covered by the filesystemwatcher class.)
So, my questions are thus:
1. How can I design a program where if the user clicks on the icon while the program is already running, the spawned copy will recognize that the program is already running and transfer control to a particular routine in the original instance? I know it can be done because there are programs that do it. What I am asking is, in effect, how do I make it so that if the user double-clicks on an icon while the program is running, instead of opening a new instance it simply brings the user to the instance already running? (And still checks the parameters being passed in, so like if I drag a file into the icon it will be recognized?)
2. If I program a COM library of functions for Visual Basic for Applications to use to control basic tasks in the program remotely, such as querying which file is being processed or changing the priority of a particular task to be run, how do I work it so that if the program isn't running yet and Visual Basic encounters a COM command, it doesn't crash? I was thinking of making a "check if the program is open" command... which I suppose would need the program to be invoked, but only the COM portion, and return a status of if the program is running or not, then close. (Or would I want it like a TSR that would keep running in the background to handle other such events?) How would I do that?
I can see that in any case there will have to be some sort of central holding place in memory to show if the program is open or not... but if I used the registry then if the program doesn't properly shut down it will still show as being open, even after shutting down the computer and rebooting. And there would probably also have to be somewhere a pointer or handle of some sort to the original thread.
Any ideas?
Thanks.

let me try and give an answer to (1). I beleive you need to look for (and there are plenty around) a SingleInstance Class to add to your application. When the app initialises it creates an instance of the Single Instance Class, which creates a system wide Mutex. If you attempt to start a second copy of the program, it runs through the same code, but the Mutex already exists - so it fires a 'bring to foreground' event.
There are some good single-instance classes around, I'll try and find the one I use and post back.
Does that sound like it answers (partially perhaps) your 1st question ?
update - this is once such case CSingleInstance - Single Instance Apps[^] Im not sure if its the one I use - I also use minimise to tray, and when the user attempts to start another copy it reactivates it from the tray ..

Ans 1:
Check the article Limiting an application to a single Instance - the MFC way[^]
Ans 2:
There are some other ways to notify other application that your application is running, like creating a name Mutex. Also you can find out whether your process is running or not by enumerating process, or trying to find your window using the "FindWindow" function. How ever I think Mutex is the easiest way.
