HRESULT SetStopNotification(HANDLE hMyEvent,
LPDIRECTSOUNDBUFFER8 lpDsbSecondary)
{
LPDIRECTSOUNDNOTIFY8 lpDsNotify;
DSBPOSITIONNOTIFY PositionNotify;
HRESULT hr;
if (SUCCEEDED(
hr = lpDsbSecondary->QueryInterface(IID_IDirectSoundNotify8,
(LPVOID*)&lpDsNotify)))
{
PositionNotify.dwOffset = DSBPN_OFFSETSTOP;
PositionNotify.hEventNotify = hMyEvent;
hr = lpDsNotify->SetNotificationPositions(1, &PositionNotify);
lpDsNotify->Release();
}
return hr;
}
Don't try it, just do it!

I just use these codes to get it, but the QueryInterface always failed. Then I try to get the interface to the CaptureBuffer, it is ok. Why these happened?

I am programming with unicode.And I don't know how to send a character with the code > 0xFF.Anyone know it.
Thank you very much...

Hi,
I don't know what do you mean with "...how to send a character..." but if what you want is assign a UNICODE character to a variable, this is how
TCHAR c = 0x0100;
Now if you are talking about UNICODE strings, use BSTR or one of the classes that encapsulate it, CComBSTR or _bstr_t.

Sorry for my ambiguous question.I want to send a message WM_CHAR with a code > 0xFF but when I use the following code :
wParam = 0x01ff
It send a character with code = 0xff.

Hi,
Could you be more specific?
If I do this
TCHAR t = 0x01FF;
SendMessage(WM_CHAR, (WPARAM)t, NULL);
when I process the message I get wParam == 0x000001FF

Silly question, but do you have _UNICODE and UNICODE defined? If you don't, TCHAR will equate to char..... and:
TCHAR t = 0x01FF;
SendMessage(WM_CHAR, (WPARAM)t, NULL);
Will truncate t to 0xFF when stored in a char varible.
Try being explicte about what character set you are sending -
wchar_t t = 0x01FF;
SendMessage(WM_CHAR, (WPARAM)t, NULL);

Hi all.
I am using a class found here http://www.codeproject.com/database/cspreadsheet.asp to create an excel spreadsheet ( i believe it uses ODBC )
It works great except I cannot, from my code, get the cells to autofit. That is, when you load up the file in Excel, a lot of the contents of the cells get cut off, because the cell is not big enough. I need to be able to tell it to autofit (automatically through code) or be able to specify the width of each column of cells. If I bring up the file in excel, and select all of the cells, then click on Column->Autofit, it makes it look right instantly ... However, I am planning on rolling out a program that generates reports and I don't want to have to tell the users that they have to do this every time they open a report.
Any help in the right direction would be appreciated!

Hi
ODBC, ADO or OLEDB will only allow you to manipulate data in and out Excel files, to go beyond that, you should use Automation, then you will be able to do, programmatically, anything you have to do.
You can take a look here to start, SAMPLE: XLCLIENT: Automation Client for Excel, also search the MSDN for more info.

Help topics are usually linked to different elements (dialogs, views) of your app. Here's what I do (which is slightly different from MS' process):
For every dialog (eg: CMyDialog), define a unique constant (eg: Help_MyDialog). Keep these constants in the file MyAppHelp.h. Include this file as a map in your HtmlHelp project. Ids in the file will map to your .chm's topic ids.
Add a "Help" button to your dialog. It's handler should execute this:
HWND hWndHelp = HtmlHelp (NULL, strHelpFile, HH_HELP_CONTEXT, Help_MyDialog); where strHelpFile is the full path to your app's .chm file.
Add a handler for the WM_HELPINFO message. This message is sent whent the user clicks the F1 key. In its handler, just call your Help button handler.

I just wonder how ::Ellipse and ::ArcTo were implemented(or CDC::Ellipse, CDC::ArcTo in MFC library), I really wish I could have a chance to see the source code of those functions, or less than that, an idea how it was possible to draw an ellipse(not a circle) on the screen, by being given a mere boundary rectangle.
I guess there got to be a lot of plane geometry involved, hell, wouldn't it be terribly time consuming to calculate coordinates of every single point on the arc?

Hi,
For most of the devices, the GDI will just delegate the drawing to the device itself because the drawing has been optimized by the manufacturer of that piece of hardware. Check the API GetDeviceCaps, it tells you if the hardware device is capable to draw the primitive, in this case, of an ellipse.

I’m trying to cal the function CreateProcessWithLogonW() who has the parameter LPCWSTR lpDomain to give the domain name. I got the current domain name in a CString variable. My problem is to convert the CString domain name to the LPCWSTR domain name to cal the function.
I have tried to use the TEXT() macro and #define UNICODE to convert the CString to an unicode string, but I cant get it to work. Is there any one that can help me with this?

Hello all
I'm new to doc/view architechture. I want to create a simple text editor which have to enable me to enter text, open files, edit,cut and copy. I'm using MFC AppWizard and accepting the defaults. It's creating a basic skeleton and when I ran it it show's up a simple editor, but when I open a file it's not showing the contents. Similarly its not allowing me to enter anything.
When creating the application if I change the base class of myview to CEditView then I'm able to do all the above operations. But I want to implement all the functionality just by deriving from CView.
Can anyone help me in this regard? Any example code or article which explains how to do will be of great help.
Thank you very much for your help.
Hari.

To create just a text editor using CView will require alot of (unnecessary) work! If that's actually all you you want to do then use CEditView (as you suggested) or CRichEditView when creating the application in the wizard. If your problem is actually that you wish to display graphics as well, then the CRichEditView will take care of that too.
Otherwise, take a look at some of the examples here on Code Project: there are many that show you how to over ride "OnPaint", which is what you're going to have to do if you wish to manually code to at least display text in a CView.
Another method (not necessarily the best: you need to be more specific as to your problem) is to write text / draw to a bit map and then simply display that in the CView. Search for "double buffering", "bitmap" or "graphics" in Code Project. "Code Guru" is another good site to try.

Hello Clevedon_Peanut
Thanks you very much for the reply. I'll try for samples in codeproject and codeguru.
Thanks
Hari.
