Thanks a lot Mr.Alok... At last we solved the problem.
Followed some instructions.., Perl installation.., some ssl supported files..., Includeing into our project.., path settings... etc etc... after lots of background work.. now it is compileing and almost working..
Thanks for giveing me support Mr. Alok. Rose | [Rose]

In my application i have a window that can display different views.

I want to generate bitmaps of some graphs, i have a graph view (CView), but it is not displayed (ie is not attached to the window) at the time.

I think what i want to do is create an offline 'dummy' CView and use OnDraw with a 'memory' dc, so that i can then write it out as a bitmap.

Does anyone have an idea of how to properly create this 'dummy' view so that it would be possible to draw? The CView's base class stuff like the CWnd* handle is not set if i just use the constructor.

I would very much appreciate any guidance.

Simon.

You can hide and show a "view" with ShowWindow() but you'll need to create the window so
the HWND is valid. When the view window is hidden you can't draw on it, so is having an
offscreen view really necessary?

If you really need to do this, you'll still have to repaint the bitmap when the window is shown
so maybe just using one view window and memory bitmap(s) is a simpler solution.

I am not sure what you are doing, but it sounds like you just need to create a bitmap of the information that can be viewed latter. Create a function that you can pass the information to and in it: (1) create a memory dc, (2) create a screen compatible bitmap, (3) select the bitmap to the dc, (4) draw to the dc, (5) restore dc to original state, (6) return new bitmap to caller. Once you have the bitmap can figure out what to do with it at a latter date, including transferring ownership to some future CView window.

Hi, thanks.

Thats the sort of thing i was trying but i'd end up with loads of black lines like a barcode.

I thought it might be because the hwnd of the view hadnt been setup properly or something. My graph data is stored seperately from the view which simply manages the DC and mouse/key strokes.

(The reason im doing it this way is that one view can be made to show different graphs)

I'm trying something that vaguely resembles...

CGraphView dummyview; (derived from CView)<br />
dummyview.SetMyGraph(graph);<br />
dummyview.SetSize(rect);<br />
dummyview.WriteToBitmap("bitmap.bmp")<br />
<br />
CGraphView::WriteToBitmap(CString file)<br />
{<br />
CDC pDC;<br />
pDC.CreateCompatibleDC(CDC::FromHandle(wglGetCurrentDC()));<br />
<br />
CBitmap bitmap;<br />
bitmap.CreateCompatibleBitmap(&pDC, rect.Width());<br />
CBitmap* oldBitmap = pDC.SelectObject(&bitmap);<br />
<br />
OnDraw(&pDC);<br />
<br />
int pixels = rect.Width() * rect.Height();<br />
BYTE* bits = new BYTE[pixels*4];<br />
<br />
glReadBuffer(GL_BACK);<br />
glReadPixels(rect.left, rect.bottom,rect.Width(),rect.Height(),GL_RGBA,GL_UNSIGNED_BYTE,bits);<br />
...<br />
bitmap.SetBitmapBits(pixels*4,bits);<br />
...<br />
then write bitmap to file<br />
}

hi need a little help with rar files

15-Mar-07 5:54

It looks like a barcode probably because the default bitmap in a memory DC is monochrome and you
are creating your bitmap to be compatible with this monochrome bitmap.

Try
bitmap.CreateCompatibleBitmap(CDC::FromHandle(wglGetCurrentDC()), rect.Width(), rect.Height());

hello everyone Smile | :)

im trying to make a c++ program that rar files.
i mean i take "blabla.avi"
and it will compress it in store method to blabla.rar
and split on 15000000 byets..
now i tryed to opened few rared files with hex editor and i manged to find thats its something like
header
filename
data from orginal file, not compressed or something because its store method
then a few more bytes..
my problem is i dont understand the header...
i tryed and searched @ google but i cant understand any explantion
here is a demo of one header:
526172211A0700CF907300000D00000000000000445374208027000300000003000000024DB1ED18368A6E361430070020000000

You can find the "UnRAR source" here: http://rarlabs.com/rar_add.htm[^]

In this package, there's a file headers.hpp, which contains all the block definitions.

I think there's some real specification, too (at least there was some time ago), but I couldn't find it anymore at the first glance.

How to make Win32 application Singleton?

I have an Win32 application. I want to make this application singleton, how to do it. Please advice.
What do I need to do to Winmain() function to make the whole application Singleton. Any help greatly appreciated.

Thanks
Turbo.

Mark Salsbery14-Mar-07 6:11

14-Mar-07 6:11

By singleton do you mean only one instance runs at a time?

If so...something like this (taken from MS recommended method):

HWND hMainWnd;
if ((hMainWnd = ::FindWindow("MyMainWindowClass", 0)) != 0)
{
   // Get other instance active popup (if any)
   HWND hChildWnd = ::GetLastActivePopup(hMainWnd);
 
   // Bring other instance main window to top
   ::SetForegroundWindow(hMainWnd);
 
   // Bring other instance active popup to top also (if necessary)
   if (hChildWnd != hMainWnd)
      ::SetForegroundWindow(hChildWnd);
 
   // Exit
   return 0;
}

Is this a service application? If so then the code I posted doesn't apply. You'd need
some other form of interprocess communication to check for another instance. A named pipe is a
simple solution.

The code I posted is for a GUI app (an app with at least one window).

Yes Singleton in the sense I want only one Application exe running. I dont understand how to use the above code. My Winmain() looks like this. Can you please tell me how to use your code in this function.

<br>int APIENTRY WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
<br>{<br>DWORD dData=0;<br>g_hServiceStopEvent = CreateEvent(NULL,TRUE,FALSE,NULL);<br>g_hMainThread=CreateThread(0,0,Func_MainThread,0,0,&dData);
<br>while(TRUE)<br>{<br>MSGmsg;<pre><br><br>if(PeekMessage(&msg,NULL,0,0,PM_REMOVE))<br>{<br>//Checkforaquitmessage<br>if(msg.message==WM_QUIT)<br>break;<br>TranslateMessage(&msg);<br>DispatchMessage(&msg);<br>}

<br>else<br>{<br>WaitForSingleObject(g_hServiceStopEvent,500);<br>}

}
CloseHandle(g_hServiceStopEvent);
return 0;
}

Thank you,
Turbo.
