No, you cannot use the class wizard here. You have to code it yourself.

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

You're referencing a method called Quicksort(std::string,int) that is defined in one of your headers but isn't actually implemented in one of your .cpp files.

today I'm in clinical raven-dead, but I'd check the fact, that:
compiler expects:
Quicksort(std::string,int)

you defines template
T Quicksort(T a[], int n)

couldn't be the array the problem?
What it generates is
std::string Quicksort(std::string a[], int n)

which doesn't actually match the required fn I guess.

XP Manifest

Do I need to have Visual Studio .NET in order to use XP Manifests, or Visual Studio 6.0 is enough?
MSDN explains how to use a manifest and tried it with VS 6.0 but it doesn't work. I still get the old theme.

Manifests are not dependent on the compiler version. Download WTL 7 from MS and check out its AppWizard, which can make projects with manifests.

Thank you very much. Downloading that now.

I created a new project (thru WTL AppWizard) with a manifest, compiled it (no changes made to it), and still I don't have an XP style. Am I missing something?

Using Multiple Tables in an Access Database

Anonymous8-Jun-03 5:03

I'm writing a small app in visual c++ 6 using MFC. The app uses an Access database to store user info and such.

In the program users can enter a bunch of data into a listbox. The problem is I don't know how much is going to be entered so I can't just create n fields in the database to hold the info.

I tired making a separate table for the ListBox entires and linking the two but searching the tables gets all messed up in my program now. I can't even use the GetTableName() function to find out what table I'm currently is.

Ideas?

What are you trying to do? How could you possible build a database where you don't know how many fields you would have? Are you building a "database maker"?

Would there be any milage in using direct CREATE TABLE SQL, formed dynamically at runtime, prefixing each new table with a unique ID?

I have seen a book once where they would teach your DirectX programming, and even though I don't know how use DirectX, I think that's what you need to use.

It appears that you're basically looking to have a set of different pre-rendered animations with connecting frames (or one giant looping animation) and you just want to vary the speed based on the BPM of music being played by other applications.

There are a number of different subprojects involved in this:

Displaying the animation -- This is probably the simplest part. You can either use DirectDraw (the DirectDraw interface is part of the DirectX 7 interfaces, available for C, C++, VB, and C# in the DirectX 9 SDK), GDI, SDL, Direct3D, or OpenGL. GDI or SDL are probably the easiest way to go here (imho).
Monitoring music being played -- Maybe try checking out the IDirectSoundCapture8 interface to get started.
Analyzing the BPM of the music -- Here you'll need to analyze the waveform and derive a beat. I haven't done signal analysis at all, so maybe somebody else can shed some enlightenment.

Clipboard problem with CRichEdit

Hi!

I want to retain only *one* text-format in a CRichEdit derived class of mine. Now if the user paste text into my edit this plan goes not so well.

Then I try something like this:

<br />
BOOL CCalEdit::PreTranslateMessage(MSG *pMSG)<br />
{<br />
 BOOL bResult = CRichEditCtrl::PreTranslateMessage(pMSG);<br />
 if(pMSG)<br />
 {<br />
  if((pMSG->message & WM_COPY) == 1 && IsKeyPressed(VK_CONTROL)):-O<br />
  {<br />
   if(::OpenClipboard(NULL))<br />
   {<br />
    HANDLE hCB = ::GetClipboardData(CF_TEXT);<br />
    if(hCB)<br />
    {<br />
     LPVOID pCB_Void = (LPVOID)hCB;<br />
     LPSTR pCB_String = (LPSTR)pCB_Void;<br />
     CString cstrCB(pCB_String);<br />
     if(!cstrCB.IsEmpty())<br />
     {<br />
       HideSelection(TRUE, FALSE);<br />
       SetSel(0, -1);<br />
       CString cstrThis(GetSelText());<br />
       ReplaceSel(cstrThis);<br />
       HideSelection(FALSE, FALSE);<br />
     }<br />
    }<br />
    ::CloseClipboard();<br />
   }<br />
  }<br />
 }<br />
 return bResult;<br />
}<br />

Seems like I got several problems.

a. My Blush | :O

-if(...) is not a 100% secure way to determine if a paste op. is in progress - ??? How do I do that?
b. Second - how do I apply my format to the text on the clipboard?

I've have a SetDefaultCharFormat() in my class that I call when I create the edit and it's the job it does that I want to apply also on the text on the clipboars *before* it is pasted in.

I appreciate any idéa.

Ps. There seems to be a LOT of WM_PASTE going ind - after some testing I ended up with: (pMSG->message & WM_COPY) == 1 - don't say it's perfect yet.

A simpler solution would be to handle the EN_UPDATE notification message, and set all the text in the control to the format that you want. You could try to make it more sophisticated by only changing the text that is new, but since the operations are fairly infrequent (in computer time...), I wouldn't worry.

FYI, EN_UPDATE notification messages are sent after the text changes, but BEFORE the display is updated - a perfect time for changing formatting.

Hope this helps

Thanx' sharing the ideas!

And actually it helped this time. What I did was that I made the CHARFORMAT-change to the full selection in response to *not* an UPDATE event but a CHANGE ev. As it turned out an update-ev. came over and over again if I did the work on EN_UPDATE - ON_CHANGE was less sensitive. So this is how the final solution looks:

<br />
const void CCalFrameWnd::CCalendar::Note_EditChange()<br />
// Called from parent to signal that user are editing a note.<br />
{<br />
	TRACE(_T("Note_EditChange()\n"));<br />
	// Ensure usage of one charformat only.<br />
	long lChar_Start = 0, <br />
		 lChar_End = 0;<br />
	CHARFORMAT cf_def;<br />
	cf_def.cbSize = sizeof(CHARFORMAT);<br />
	m_pEdit_Note->GetDefaultCharFormat(cf_def);<br />
	m_pEdit_Note->GetSel(lChar_Start, lChar_End);<br />
	m_pEdit_Note->HideSelection(TRUE, FALSE);<br />
	m_pEdit_Note->SetSel(0, -1);<br />
	m_pEdit_Note->SetSelectionCharFormat(cf_def);<br />
	m_pEdit_Note->SetSel(lChar_End, lChar_End);<br />
	m_pEdit_Note->HideSelection(FALSE, FALSE);<br />
}<br />

So I just force the def-CHARFORMAT on to the entire selection having always set the def-format first. Also I remember to be able to restore to the orig. caret pos.

It works! Rose | [Rose]

Blush | :O

Oops. I forgot to mention that by setting the text formatting, you cause another EN_UPDATE message to be sent, which becomes an endless recursion. You would need to set a static/class-member variable inside the handler and check it when the handler is entered to see if you're already processing the message, and return immediately if you are.

Glad to be of help Smile | :)

C++ GUI library question

I need a cross-platform C++ GUI library for a new project I'm working on. Am not particularly thrilled with the current cross-platform library options I've run across. Would like to find a GUI library that works similar to and as easily as a browser, where you can input text and various controls to display on the screen using a hypertext language like HTML or embed instructions for screen layout in the code. Are there any cross-platform C++ GUI library projects in the works that sound similar to this and/or might need another developer
to help out? Are there any new cross-platform C++ GUI projects starting up that might need developers? It would be nice to get involved with a group to work on this rather than my trying to code a new GUI library all by myself. Suggestions appreciated.

Thanks.

Anyone have any other ideas?
