I know this, but this implementation is for windows. What I want to do is to create an implementation that works in linux too....
A generic thing, ok?

I haven't seen an open source screen capture program, that works on both platforms. XVIDCAP[^] is open source and is for Linux. Hope that helps.

You're most welcome Alex.

FYI, osalt.com[^] has a wide variety of open source programs and you can search for an open source program by providing a commercial program's name. Smile | :)

Very thanks again. In the last days, I was searching a site that seems to sourceforge and now I found.
Very helpful.

BTW, is there other sites like these

hi, i wondered how i can do this with ostringstream
i want to print time in this format: mm:ss
for minutes=5, seconds=2 it should be 05:02 for example

any ideas? thanks in advance

I think you got 1 because your code will not properly format numbers (BTW I didn't vote you).

I didn't vote you down but this doesn't answer the question. This would be equivalent to printf("%d:%d");
So there's no lenght and filling specification.

Thanks, it worked perfectly.

btw, it seems an awkward construction, with printf the formatting is more natural. guess the new c++ classes can't be better at everything...

all the lines explained by CPallini can be "inlined" into once (if i remember well)...

Yes, it can be done, including <iomanip> and slightly changing the syntax:

#include <iomainip>
//...
str.fill('0');
str << setw(2) << 2 << ":" << setw(2)  << 5 << endl;

I agree, that's why I tend to use printf family functions. On the other hand manipulator syntax is great for dealing with complex objects.

also, you (and the OP) must be aware that printf()-like functions are not thread safe, were C++ xxstream classes are.

create an Event to a TreeView

sabeeshcs19-May-08 2:41

Hello,
I have a class in MFC and I want to use this class in Windows forms. For that I create a .dll file using the MFC class and load that .dll file in to CLR project and draw that object in Windows form. But now I want to add an event to that new control. How can I do this?
eg:
I have a ctreeview in MFC and I create a .dll file using that MFC class and open a CLR project in VC++2008 and add a form to that project and load that .dll file. Then I can access that MFC class in my new Windows form ( in CLR project ). and it is working. But my current problem is that, I want to read selected node value from that tree node to my Windows forms's text entry. How can I do this? I think, for that we need to add an event ( After select ) to that control. But that control is loaded from .dll file.
How can I solve this problem?
Please help me.

Help clarify "this" pointer with dialog boxes

Kwanalouie19-May-08 1:59

Using Visual C++ 6.0 MFC in SDI application

I typically get confused with the "this" pointer. For example, I created a Dialog Box using Visual C++ 6.0 MFC. Its class has its own .cpp and .h files (Class name for this dialog box is CMyCustomDlg). In the book "Using Visual C++ 6" by Jon Bates and Tim Tompkins on page 219 they talk about Displaying a Modal Dialog Box. They say to declare a dialog class object local to the function handler, such as

CMyCustomDlg dlgMyCustom(this);
//and then display it using
int nRetCode = dlgMyCustom.DoModal();

where CMyCustomDlg is the class name given to this dialog class. I don't understand what is happening here with the "this" pointer with this type of syntax and what the (this) in parenthesis means, and I don't understand where I can use

CMyCustomDlg dlgMyCustom;
int nRetCode = dlgMyCustom.DoModal();
without putting the "this" in parenthesis in the object declaration.
Thanks ahead of time.

the this in parenthesis is the pointer of the current instance (the meaning of this) passed as a parameter to the CMyCustomDlg class constructor.
