I have to write a dialog-based program (using MFC) which saves the position of the dialog to Window registry when user log off Window.
I've tried to save dialog's position in DestroyWindow() function but it doesn't work.
Could u tell me a way to solve this problem?
Thank in advance.

Does anyone know of any DVD/CD burning libraries that are opensource or shareware? I know of a few which cost a bit and I may eventually break down and buy them... but I'd prefer to ease the learning curve by starting with something cheap that I can play around with.

Thanks!

Why don't you try nero API, it is free. But you and those who will use your program would need a nero installed.

I have a CRichEditCtrl object that contains multiple lines of data. Each line is from 1100 to 2030 characters long. For some reason the rich text control is word wrapping the line at character 1025. Can anyone suggest a way to avoid word wrapping? I do not want any wrapping at all.
Thanks in advance for your help.

You might check this link out:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/vcrefcricheditctrlsetwordwrapmode.asp
I've not used this control, but you could potentially override the default wordwrap handler via the EM_SETWORDBREAKPROC message. I don't know if this would work, but perhaps by taking over the wordwrap responsibilities you could effectively disable it.
You might check here, too: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/richedit/richeditcontrols/richeditcontrolreference/richeditmessages/em_setwordbreakprocex.asp

best of luck.

Have you enabled run-time type info (/GR compiler option)? Have you #include typeinfo.h?

Hi All,
I want to do Intelligent bitmap depth conversion.
Convert XXX to XXX (without color lose):
24 bits --> 16 bits (If few color used that can fit in 16 bits)
24 bits --> 8 bits (If few color used that can fit in 8 bits)
24 bits --> 4 bits (If few color used that can fit in 4 bits)
24 bits --> 1 bits (If few color used that can fit in 1 bit)
Do u know, How I can find this bitmap has exact color(with no color lose) to fit in lower depth?
For example : If I have a 24bits baitmap, but that is using only two colors. These two colors can be shown by 4 bits bitmap without any lose of color, then I should use 4 bits bitmap WHY 24 bits.
Thanks

There are a few articles on working with bitmaps at CP. I do not remember if CxImage supports bitmap color depth conversion, but it supports multiple image formats. The CDibData class does support such conversion, but I never did get around to updating it (a bug-dealing with compression).
The only reason for converting your two color bitmap, from a 24-bit format, is to reduce the storage requirements. Think about that; a 24-bit image stores each pixel value in 3-bytes, a 4-bit image stores two pixels values per byte. A 4-bit bitmap image does require that a palette be provide, but that palette will, in this case, have only two entries.

Every thing is relative...

16-bit colour simply allocates fewer bits per colour than 24-bit. A common 16-bit format which is easy to describe uses 5 pixels each for Red, Green, Blue, with one unused, i.e. it is 15-bit. True 16-bit allocates 6 bits for green, I think.
To check whether an image is entirely suitable for 15-bit, you could use brute-force, and step through every pixel, checking that the 3 least-significant bits for each colour are all zero. Theoretically, you loose information if you discard non-zero bits.
Alternatively, you could just force 24-bit images to 16-bit, but this can give visible changes in the image.
To convert to 8-bit per pixel or lower, I don't think there is an easy way.
I would allocate a 256-member array for 24-bit colour values, then step through the pixels, one by one. For each pixel, check if the value is in the array. If the colour value is in the array, go on to the next pixel. If it is not, add its colour value to the array. If the pixel's colour value is not in the array, but the array already has 256 colour values, then sorry - your image can not be converted to an 8-bit image without loss of quality!
((I seem to remember something about 16 "system reserved" colours in an 8-bit image, so you may only be able to use 240 colours.))

for 24 to 16 no idea come to mind...
For 24 to 8 bit.. ya..you are right I have to iterate and find out about color usage, that's already going in my mind,
For 256 colors we can make 216 colors by combinations of(0,51,102,153,204,
255)and other 40 colors I have not found yet..how to find these..
But I don't think, it's a good idea. I m working in this direction..but mind is still trying to avoide this method.

Hello all,
I have a CDialog derived class that is set as Child, no border, no title bar, no menu. I am using this dialog as a child in another dialog. BUT, I would like to use this child dialog as a MODAL dialog. If I use this code :
{
CDlgEcu locDlgEcu;
if( locDlgEcu.DoModal() == IDOK ){
// ADD DATA TO LIST
}
}
then I can see only some controls from this dialog and dont see dialog backgroud, title bar, border ...
if I try to use ModifyStyle so this function set some of flags but not all that I need ....
this code dont work:
ModifyStyle( (~0x00), WS_POPUP|WS_VISIBLE|WS_CLIPSIBLINGS|WS_CAPTION|(WS_SYSMENU|WS_THICKFRAME)
);
ModifyStyleEx( (~0x00), WS_EX_CONTROLPARENT|WS_EX_WINDOWEDGE);
Does anybody have ANY advice, please?
thnx.

I would like to capture the text or the HTML code from a page displayed in Internet Explorer.
I try to achieve this by enumerating all windows that match "Internet Explorer_Server" class using EnumWindows() and EnumChildWindows()to get the handle to the window and IHTMLElement to get the HTML code. But this doesn't work with a page that uses frames. It only reads the text from one frame.
Does anyone have an ideea of how I can achieve this?
<br />
if (strTemp==string("Internet Explorer_Server"))<br />
{<br />
CoInitialize(NULL);<br />
HINSTANCE hInst = ::LoadLibrary( _T("OLEACC.DLL") );<br />
string strTemp;<br />
CComPtr<IHTMLDocument2> spDoc; <br />
LRESULT lRes;<br />
<br />
strTemp="";<br />
UINT nMsg = ::RegisterWindowMessage( _T("WM_HTML_GETOBJECT") );<br />
::SendMessageTimeout( hwnd, nMsg, 0L, 0L, SMTO_ABORTIFHUNG, 1000, (DWORD*)&lRes );<br />
<br />
LPFNOBJECTFROMLRESULT pfObjectFromLresult = (LPFNOBJECTFROMLRESULT)::GetProcAddress( hInst, _T("ObjectFromLresult") );<br />
if ( pfObjectFromLresult != NULL )<br />
{<br />
HRESULT hr;<br />
hr = (*pfObjectFromLresult)( lRes, IID_IHTMLDocument2, 0, (void**)&spDoc );<br />
if ( SUCCEEDED(hr) )<br />
{<br />
CComPtr<IHTMLElement> pHTMLElement; <br />
hr=spDoc->get_body(&pHTMLElement);<br />
BSTR bstrText;<br />
pHTMLElement->get_innerHTML(&bstrText);<br />
strTemp=(char *)_bstr_t(bstrText);<br />
<br />
MessageBox(hwnd, strTemp.c_str(), "text", 0);<br />
<br />
}<br />
}<br />
::FreeLibrary( hInst );<br />
}<br />
<br />
This is how I get the text when I have the handle to the "Internet Explorer_Server" window.

Read the IHTMLDocument2::frames property to get a list of all frames under the top-level HTML document. You'll have to recurse through that collection since frames can have sub-frames.
For each frame object, QI it for IHTMLWindow2 and then read the document property. You can then use your existing code to read the contents of that document.

Here is a vc 6.0 project, in which there is a link fatal error that cannot open file "..\bin\release\xxx.lib".
I set all the tabs in project->setting and open all files in notebook to find this string.
However, after doing these, the error appears after rebuild all.
Why?
Thanks!

It could be the order that the files are built. When you do a rebuild all the first thing that happens is that all the files are deleted, then they are rebuilt. If your main app (the one that needs xxx.lib) is built before xxx.lib it will not be able to find xxx.lib. Make your app dependant on xxx.lib so that xxx.lib gets built first. Use Project->Dependancies for this.

Hi,
I am having some problems with a project of mine (inherited actually). It was probably converted from the older VS.Net to VS.Net2003. I am having those corrupted metafile database link error. I was told that I should start from a clean VS.Net2003 project and import the old files back. The problem is that the files for Windows Forms look different in the solution explorer than before. In the old project, I can see the form icon next to the header file and a resource file show as a child under it. Now these related Windows Forms files seem to be unrelated in the Solution Explorer and I can no longer double-click on the header file to start the form designer. What is the correct way to rebuild a project from the source files? The only way that I can think of is to create a Windows Form application and then add the new forms that has the same names as the old ones. After that, I will simply overwritten the new files with the old ones. I figure that this must be a dumb way of doing it. Can you give me some idea how to do this in a smart and faster way?
Thanks very much.
Dennis

Hello everyone! 
OK, I'm just trying to open a file with CreateFile() and ReadFile(), but ReadFile() only reads until line 65 of my file, and that line ends with some weird characters... This happened to me in C#, where I used the StreamReader.Flush() method, but how do I do it in C++? FlushFileBuffers() doesn't work... Thanks!

How big is the file (byte count)? How many bytes did you read? Could you show us some actual code?

ReadFile() has no concept of a line. What exactly are you trying to do?
