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?

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.

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  -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 />
{<br />
TRACE(_T("Note_EditChange()\n"));<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]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

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

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.

I checked out the page you mentioned and wrote to the contact e-mail address there. Was told the information on the page is very old and hasn't been kept up-to-date.
Anyone have any other ideas?
Thanks.

Hello,
how can I determine if the current build is a Unicode build? Is there any flag defined that tells me that?
For example I have this function:
{
unsigned long uStringLength = string.GetLength();
LPTSTR lp = string.GetBuffer(uStringLength);
DoBinaryWork(lp, uStringLength);
string.ReleaseBuffer();
}But if building a Unicode build this code will not work because Unicode takes 16 bits per character, therefor only the half of the string is passed to the DoBinaryWork function.
How can I check if building Unicode? I assume there is a flag that can be checked with #ifdef, but what is it?

the UNICODE macro is defined if UNICODE is enabled. Alternatively you could overload DoBinaryWork to take a wstring (basic_string<wchar_t>) or a string (basic_string<char>) which may be possible

I'm a little confused by this.
CString::GetLength() returns the length in characters - so it still returns the correct string length, and if the DoBinaryWork() function takes a LPTSTR, then it also should work correctly.
This code should work unchanged under both ANSI and UNICODE builds.

CString::GetLength() returns the length of the string in characters (as you said), but I need it as bytes. A CString character can be 8 or 16 bits long, therefor number of bytes != number of characters.
The DoBinaryWork function takes an unsigned char * as parameter. I forgot to place a cast to the unsigned char * in the code example, sorry.
Any idea how to check for Unicode?
