May be this is not the right forum to ask as this question relates to Borland C++ v 3.1. I could not find that topic in this. Suggest me the right forum. I am not able to debug my borland C++ project. When i press F8 it says 'no debug info at program start.Run Anyway' I checked the compiler options. Debug info is enabled. Is there anything i am missing?
Thanks for your help

Did you set debug options for it?
|
|
|
|
|
yes..I enabled degug option in the compiler settings. But still is of no use

I'm building a filtergraph and I'm sort of new at this. I want to build a filter graph that takes input from a Windows Media Player to capture the audio, whether I'm playing music or a video. I read about a filter with the class id of CLSID_WMPCD and I tried to access it from Direct Show on my PC, but wasn't able to. I Googled it and it wasn't anywhere to be found. Does anyone know anything about it, and is there possibly a CLSID_WMPDVD?
Thanks for any help anyone can provide.

The class is used for recording informations which may be massive.In the initialization:
<code><pre>m_qwFileSize = 0x4000000;
m_qwFileOffset = 0;
m_T = 600 * m_siInfo.dwAllocationGranularity;
m_hMappingFile = ::CreateFileMapping(m_hFile,NULL,PAGE_READWRITE,0,m_qwFileSize + sizeof(TCHAR),NULL);
m_lpStartLoc = ::MapViewOfFil(m_hMappingFile,FILE_MAP_ALL_ACCESS,static_cast<dword>(m_qwFileOffset >> 32),static_cast<dword>(m_qwFileOffset & 0xFFFFFFFF),m_dwBytesInBlock);</dword></dword></pre></code>
When the view's size is larger than 60%,I re-mapping the file:
<pre><code>if (m_qwFileOffset >= m_T){
m_T = m_qwFileOffset + 600 * m_siInfo.dwAllocationGranularity;
::UnmapViewOfFile(m_lpStartLoc);
__int64 qwOldFileOffset = m_qwFileOffset;
RndToSysAllocGranularity(m_qwFileOffset);
__int64 qwOffVar = qwOldFileOffset - m_qwFileOffset;
m_lpStartLoc = ::MapViewOfFile
(m_hMappingFile,FILE_MAP_ALL_ACCESS,static_cast<dword>(m_qwFileOffset >>
32),static_cast<dword>(m_qwFileOffset & 0xFFFFFFFF),m_dwBytesInBlock);
PBYTE pByte = reinterpret_cast<pbyte>(m_lpStartLoc);
pByte += qwOffVar;
m_lpStartLoc = pByte;}</pbyte></dword></dword></code></pre>
in the RndToSysAllocGranularity(), I allocate the File offset:
<code><pre__int64 dwremains="dwValue" %="" m_siinfo.dwallocationgranularity;<br="" mode="hold" /> if (dwRemains){
__int64 dwDevided = dwValue / m_siInfo.dwAllocationGranularity;
dwValue = (dwDevided + 1) * m_siInfo.dwAllocationGranularity;}</code>
When it works, I get the errors and its error code is 0x5,it means access denied.Why?
Later buggers harm more.

We have a native Visual C++/MFC app, and have a dialog which contains a web browser control.
The web browser control is a CWnd-derived class which uses InvokeHelper to communicate with the browser control. We call Navigate2() to send it to a URL and display the HTML in a child window within our dialog. This works great.
The question is how do we go about handling HTML events in the containing C++ dialog? For example, suppose we have a button in the displayed HTML which has an onclick event handler. We'd like the user to be able to click on the button in the HTML and have the containing MFC dialog get the event.
How do we communicate events out to the containing dialog?
The specifics of the control we're using are below. This is whats in the registry under the CLSID referenced in the wrapper class.

So you did not use the CDHtmlDialog MFC class[^]? Why not?

I'm adding this to an existing dialog. I don't want the entire dialog to be HTML. I want to have regular controls on the dialog and then have one area of the dialog display HTML content.

I have several vecors, loaded with data. I need to insert this data into a presentable display in a large RichEdit Editbox.
Since the data will vary in how many records will be displayed, I need a portion fixed to display the top portion of the "Form" and then just add the data afterward.
I'm afraid I'm at a loss as to how to begin. Could anyone supply some code as to how to load from file a "Form"(letter actually) and then be able to insert data after that "Form is displayed; thenn I would save the entire document to file.

Why don't you use a ListView instead?

The data is alin a ListView. But I need to present a "Document" (I'm NOT using MFC's Document interface)for viewing and printout.

I would start by looking at EM_STREAMIN. In the callback function, extract the data from your vectors.

Since I know next to nothing about EM_STREAMIN I have to ask? How do you use it in MFC. Somewhere I saw an example uing SendMessage which require a HWND as the first item in the SendMessage(HWND,...,....,);. How do you use SendMessage in MFC, in a dialog's Editbox?

Since you are using MFC, just call the CRichEditCtrl::StreamIn() method.
