I'm somewhat embarrassed to ask this, but as I said I've not done this before. I goofed this up somehow and ended up with a hex file instead of my bitmap.

On the control's properties there is a Type combo (set it to Bitmap) and an Image combo (set it to the resource ID of the bitmap to show). You can also set the bitmap at runtime with the STM_SETIMAGE message.

If the bitmap doesn't use the 16 standard colors, I'd recommend CWndImage[^] (if you use MFC)
deals with pixel-vs-dialog units size and palette issues.

Thanks to all replies. I must have just been over tired last night. Didn't have any problems with it today and I appreciate the help.

Are there any other good C++ forums that you know about. I mean the Forums like Sun has for java. This one is good but still there may be others........

I think that programmers heaven is decent (at times) so you might want to check that out.. has seperate forums for C/C++ w/ and w/o MFC.

Programmer's heaven is ok but i could have been better. I was using the Java Forum hosted by Sun http://forum.java.sun.com/, it's real great

www.codeguru.com is another good one. It has java forum maybe you are interested.

hi, i've written a simple application that display a sequence of bitmap in the VIEw of a MFC/SDI application.
There're four components to the implementation:
(1) timer itselg
(2) View_Class::OnTimer(..)
{
Invalidate(); //Trigger View_Class::OnDraw()
(3) View_Class::OnDraw(..) is responsible for rendering the bitmaps to screen.
(4) Document class - handles all bitmap loading
(4a) Constructor:
STEP 1: Pre-load a few frames
STEP 2: launch a thread - LoadFrames( ) - that load the rest of the bitmap sequence.
hThread = CreateThread( NULL, 10000000, (LPTHREAD_START_ROUTINE) LoadFrames, this, 0, &nThreadID);
As you can see, I did allocated 10MB worth of memory here!
STEP 3: set timer
(4b) LoadFrames( ) //This method loads a bunch of frames to document class
{
//ERROR!!
hBitmap = (HBITMAP) ::LoadImage(AfxGetInstanceHandle(), sPath, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE );
if( hBitmap != NULL)
{
pDoc->GetBitmapSeq(i).Attach(hBitmap);
}
else
{
//Out of memory?!?! NOTE: dwError==8 implies "ERROR_NOT_ENOUGH_MEMORY"
//System monitor shows that the thread never had more than 2.5MB!??! How can it run out of memory??
DWORD dwError = GetLastError();
}
}
Thanks

Three problems that I can see:- A thread that uses MFC must be created by
AfxBeginThread(). - The stack size parameter has no effect in this situation, as you're not creating bitmaps on the stack.
- The
HINSTANCE param to LoadImage() must be NULL when using LR_LOADFROMFILE
Good luck

thankyou... i tried using CAnimateCtrl but doesnt seems like it helps..
MCI control is a lot better, especially with memory requirement. But seems like it's a little jerky. QuickTime is the best thus far - which makes me wonder why we need avi in the first place.

Hi, I launched a thread that's responsible for loading a sequence of bitmap into memory, so, I need a lot of memory for this thread. Here's the code fragment:
unsigned long nThreadID;
HANDLE hThread;
hThread = CreateThread( NULL, 5000000, (LPTHREAD_START_ROUTINE) LoadFrames, this, 0, &nThreadID);
So, as you see, I've allocated 5MB of memory to this thread. However, I keep getting memory allocation error from my thread function:
long WINAPI LoadFrames(LPARAM lparam)
{ //*
...
...
hBitmap = (HBITMAP) ::LoadImage(AfxGetInstanceHandle(), sPath, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE );
if( hBitmap != NULL)
{
pDoc->GetBitmapSeq(i).Attach(hBitmap);
}
else
{
//Out of memory!! dwError==8 implies "ERROR_NOT_ENOUGH_MEMORY"!!?! I really dont understand, I was monitoring the system monitor and the thread has less than 3MB allocated to it.
DWORD dwError = GetLastError();
... more exception handling code...
}
return 1;
} //*
Thanks!

You are allocating a 5M Stack for the worker thread. Is that what you really want? Where does LoadImage() get its memory from. I doubt that its the stack.

Thanks for the feedback first of all. LoadImage return a BITMAP hBitmap which is stored in a variable (of type BITMAP of course) in the "thread function". The images sequence is stored in a CBitmap array in the document class, which is separate from the thread... so, all I need is just enuf memory for ONE bitmap (700kB), and yes 10MB is an overkill, but I really dont understand why LoadImage results in memory error:
long WINAPI LoadFrames(LPARAM lparam)
{ //*
CString sPath;
HBITMAP hBitmap = NULL;
CAutoPlayMFCDoc * pDoc = NULL;
pDoc = (CAutoPlayMFCDoc*) lparam;
//Load the rest of the frames!
for(int i=NUM_PRELOAD; i<num_bitmap; i++)
="" {="" **
="" spath="pDoc-">GetPath();
if( sPath.GetLength() > 0 )
{ //***
hBitmap = (HBITMAP) ::LoadImage(AfxGetInstanceHandle(), sPath, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE );
if( hBitmap != NULL)
{
pDoc->GetBitmapSeq(i).Attach(hBitmap);
}
else
{
//That's the problem: dwError==8 implies "ERROR_NOT_ENOUGH_MEMORY"
DWORD dwError = GetLastError();
pDoc->SetLoadState(1);
i = i -1; //reload the frame
break;
}
//Increment m_nTargetDocFrame:
pDoc->SetTargetDocFrame(i);
} //***
} //**
return 1;
} //*

The "dwError==8 implies "ERROR_NOT_ENOUGH_MEMORY"" may be a red herring. If you move this code into the main app thread does it work?

Yes, after I adjust the number of frames to be preloaded in the document class' constructor, i got the same error (from LoadImage() in document class constructor)...
How can I adjust the memory for the mainthread? or the application thread?

I don't think it is a memory problem. Maybe there is a problem with the bitmap you are loading. Why don't you try some others, including some smaller ones.

what do u mean problem with bitmaps? anyway, your suggestion "try smaller bitmap" is probably pointing to the right direction, it seems that the application consistently returns error (dwError = 8) around the time when it finishes loading the 32nd frame.
But u're right, it's got nothing to do with memory allocated to the thread.

Hello -
I'm building a product that requires an html wysiwyg editor - I upgraded to Visual C++ .NET (7) to get MFC 7 - with the CHtmlEditView / CHtmlEditDoc classes, only to find that there is no IDM_TABLE command.
I also tried inserting using IHTMLDocument2:
BSTR str = SysAllocString(L"<table width=\"100%\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\" bordercolor=\"#CCCCCC\" bgcolor=\"#E6E6E6\"><tr><td width=\"11%\"> </td></tr></table>");<br />
<br />
IHTMLDocument2 *pDoc;<br />
long col=0;<br />
IDispatch * pDocDisp = NULL; <br />
<br />
pDocDisp = GetHtmlDocument();<br />
HRESULT h = pDocDisp->QueryInterface( IID_IHTMLDocument2, (void**)&pDoc );<br />
if( h == S_OK )<br />
{<br />
IMarkupServices *pMS = NULL;<br />
IMarkupPointer *pMkStart = NULL;<br />
IMarkupPointer *pMkFinish = NULL;<br />
<br />
<br />
CComPtr<IHTMLElement> pElement; <br />
HRESULT hr = pDoc->createElement(L"TABLE", &pElement);<br />
pElement->put_outerHTML(str);<br />
<br />
pDoc->QueryInterface(IID_IMarkupServices, (LPVOID *) &pMS);<br />
pMS->InsertElement(pElement, pMkStart, pMkFinish);
and also tried IHTMLTable / QueryInterface. None worked.
If anyone has a solution to my problem I'd be greateful.
Thanks.

IHTMLElement has a function called InsertAdjacentHTML.
BTW: I would recommend you to use smart pointers which make life a lot easier, and they also help avoiding memory leaks.
Just us it as follows:
IDispatchPtr pDisp = ...
IHTMLDocument2Ptr pDoc(pDisp);
IHTMLElementCollectionPtr pCollection;
pDoc->get_all(&pCollection);
IHTMLElementCollection pAllTables(pCollection->tags(CComVariant("table")));
...
|
|
|
|
|
As someone said, insertAdjacentHTML is a fine stuff :
CComQIPtr<IHTMLDocument2> pHtmlDoc( GetHtmlDocument() );
CComBSTR bstrWhere = "BeforeEnd";
CComBSTR bstrText = ...;
CComPtr<IHTMLElement> pBody;
pHtmlDoc->get_body( &pBody );
pBody->insertAdjacentHTML( (BSTR)bstrWhere, (BSTR)bstrText);
How low can you go ?

Thanks for the responses. One question - is insertAdjacentHTML feasible for drag drop operation, i.e.,
a la IDM_TEXTBOX message - simply drops edit box on
CHtmlEditView.
What I'd ultimately want to do is to be able to insert
a table based on parameters entered in dialog, then
drop table onto CHtmlEditView. Similar to the DHTMLedit component using IDM_TRIED_INSERTTABLE.
Thanks a bunch for responding so quickly.
