You might consider calling
InitialUpdateFrame(pFrame, pDocument, bMakeVisible);
which will actually refresh the view and update the title.
Hope it works.

Hi 
In my dialog I have two Date/Time-Picker-controls...one to select a date and another to select a time. I also have two variables, named
CDateTimeCtrl m_ctlTime;
CDateTimeCtrl m_ctlDate;
What's the easiest way to read their values (date and time) into one single CTime variable?
thanks in advance

Use the overloaded construter
CTime( int nYear, int nMonth, int nDay, int nHour, int nMin, int nSec, int nDST = -1 );
|
|
|
|
|
Try this...
SYSTEMTIME st;
m_ctlDate.GetTime(&st);
m_ctlTime.GetTime(&st);
CTime time = st;

Using this approach the second call to 'GetTime' refill the time value
effectively erasing the previous value obtained from m_ctlDate.

Sorry - previous message contains invalid answer. This should work OK:
SYSTEMTIME stDate, stTime;
m_ctlDate.GetTime(&stDate);
m_ctlTime.GetTime(&stTime);
stDate.wHour = stTime.wHour;
stDate.wMinute = stTime.wMinute;
stDate.wSecond = stTime.wSecond;
CTime time = stDate;

Thanks guys!
What about using Prem's approach?
Instead of CDateTimeCtrl I made the varables CTime with names m_timeTime and m_timeDate
Thus I used this code:
UpdateData();
CTime Time(m_timeDate.GetYear(), m_timeDate.GetMonth(), m_timeDate.GetDay(), m_timeTime.GetHour(), m_timeTime.GetMinute(), m_timeTime.GetSecond());
Seems to be quite easy as well

For large no. of clients connect to server during the load test,getting the connection refused error,even if at server side the backlog in listen() method of the socket is put to maximum SOMAXCONN and creating the user thread for each user after accept.
How to solve this prob.

How many do you want it to keep in a backlog? Using SOMAXCONN justs tells the service provider to pick a reasonable value. This value could differ between service providers.
So basically, you can't flood your server with connection questions and expect them all to be placed on the backlog. That would actually be a bad design since you could in theory DOS the server by exhausting its memory with a huge backlog of connection requests.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

You gain nothing by calling listen each time after accepting. The standard sequence is: listen once and then loop around accept.
Is you're having connections refused, try to speed up your accept-associated code. Your maximum rate of clients served per second is 1/t, where t is the time it takes to your app to accept a client. No backlog will improve that appart from providing some resiliance against temporary rushes. In Winsock 1.1 the maximum backlog is 5 (admittedly a little low), if you're using Winsock 2 you can set a more comfortable backlog size (though the value of SOMAXCONN for Winsock 2 is an overkill (0x7FFFFFFF), and you're better off setting something smaller than that.)

How I can copy system registry files in win 2k? (winnt\system32\config\*.*) IMHO... it's posible only under DOS... What is your opinion? Sanks...

I was wondering how to create an SDI app thats view is one of a Shockwave Flash movie viewer. For example the flash viewer/projector app. I know that you can include it as an ActiveX control in a dialog but how would it work for a doc/view app.
Any examples/tutorials would be greatly appreciated.
.NET or not .NET? MFC is the question......

You could use a CHtmlView and make it load the .swf file

Does anyone know if there is a way to return the files from the functions FindFirstFile and FindNextFile sorted by name !?

AFAIK, it's not possible. You'll have to sort yourself - just store the names in std::vector and call std::sort.

Hi !
I have a SDI application which has the view derived from CFormView (the resource for this view is IDD_CONTAINER).
I have to create some DLLs which will be loaded dynamically at runtime by the SDI application (at some stage only a DLL is loaded).
These DLLs will use the CFormView's resource (IDD_CONTAINER), the view window is actually a container window for those DLLs.
The DLLs are MFC Extension DLL (using shared MFC DLL).
Could anyone explain me how to do that (eventually some examples)?
Many thanks,
Vasile

With extension DLLs you should have no problems with resources - .exe and all extensions will have their resources chained; all MFC functions dealing with resources will search through all MFC-based modules.
To get access to resource #defines, include resource.h from .exe project in .dll projects.

?? You mean that there will be no .exe?

The .exe will be that container application...but when the app has to load a new dll, it will unload first any other dll loaded before.
Thanks

I have done something very similiar recently...
I've used a CTabView in my executable that shows dialogs loaded from extension DLL's.
I pass a controlling class to the DLL, and the dll calls a function to add a tab.
control->AddTab(myDlg->GetSafeHWND()).. the only thing that caused me some headache was the AFX_MANAGE_STATE(AfxGetStaticModuleState()); I had to insert in the correct places...

Hi
I'm going round in circles and could do with some help. I have an application that draws a whole lot of information to a window via a subclass of CView. Now I need to save a copy of what is in the window in a particular format. I thought if I created a new view using a memory device context I could get the system to draw itself to this new view and then pull the required data out of memory but I can't seem to find a way to set up a memory device context with the format that I want (16bit gray scale would be ideal - i'll settle for 8bit if I have to).
CreateDC wants me to specify a lot of stuff about drivers .
CreateCompatibleDC gives me something according to the current system device, but trying to select a bitmap of a particular format into this fails because the two are not compatible. CreateCompatibleBitmap seems to give me a monochrome bitmap.
I'm sure it is very easily done but my brain has gone fuzzy.

CreateDIBSection accepts BITMAPINFO on input, this allows you to specify the color depth.

Seems a good idea. Now I have the following..
---------------------------------------------------------------------------
CDC dcMem;
dcMem.CreateCompatibleDC(NULL); // Needed otherwise handle is uninitialised
// Set up all the BITMAPINFO data
char pDIBHdr[sizeof(BITMAPINFOHEADER) + 256*sizeof(RGBQUAD)];
BITMAPINFOHEADER *pBitmapInfoHdr;
RGBQUAD *pRGB;
pBitmapInfoHdr = (BITMAPINFOHEADER *)pDIBHdr;
// Setup the header information for the device independent bitmap which
// is going to be used
pBitmapInfoHdr->biSize = sizeof(BITMAPINFOHEADER);
pBitmapInfoHdr->biWidth = 256;
pBitmapInfoHdr->biHeight = 256;
pBitmapInfoHdr->biPlanes = 1;
pBitmapInfoHdr->biBitCount = 8;
pBitmapInfoHdr->biCompression = 0;
pBitmapInfoHdr->biSizeImage = 0;
pBitmapInfoHdr->biClrUsed = 0;
pRGB = (RGBQUAD *)(pDIBHdr + pBitmapInfoHdr->biSize);
for(int ii=0;ii<256;ii++){
pRGB[ii].rgbRed = ii;
pRGB[ii].rgbGreen = ii;
pRGB[ii].rgbBlue = ii;
}
void* pTmpMem;
CreateDIBSection(dcMem.m_hDC,(BITMAPINFO *)pDIBHdr,DIB_RGB_COLORS,&pTmpMem,NULL,0);
dcMem.Rectangle(CRect(0,0,100,100));
pData = (short *)pTmpMem;
// Now use pData to access the actual data out of the bitmap
--------------------------------------------------------------
The output I now get doesn't reflect the Rectangle draw that I performed.
Should it ? Although I have created this DIB is it selected into the DC as the memory surface onto which the draw functions will be occurring. If not how does one achieve that, so that the draw functions accessed via the DC will write into this DIB.
Thanks
Andrew

You've forget to select your DIBSection into dcMem. The first paremeter you're passing to CreateDIBSection is used only to initialize DC palette when you pass DIB_PAL_COLORS as 3rd param.

Hi All !
I have read that the C# threading classes in .NET causes an
exception to be thrown in a thread if that thread is being ended
by another thread.
Any idea's on how to implement this with VC 6.0 ? This could provide an
excellent alternative to polling for stop flags.
Kind regards,
Alwin
