Hello,
I have a CDialogBar with many run-time-generated progress bar windows on it. I would like to know when the user clicks on one of these progress bars but after trying many message map entries, I cannot seem to find the right way to funnel these messages to any function of mine.
I've tried to simply intercept the ON_WM_LBUTTONDOWN message, but it is only called if the user clicks in the dialog bar EXCEPT for in my progress bar windows.
Any ideas/help?
thanks!

Sounds like you have to handle the message within the progress bars, not in the CDialogBar.

Thanks for the reply. Can this 'clicked' message be reflected back from the CProgressBar to the CDialogBar in which it exists? I'd really love to handle it in the dialog class instead of the progress bar class.
thanks!

Should work. See TN062 in MSDN.

I need to find out how to open\write to a file and then close it. I just need to record the time at point 1 to the file and the record the second point 2 time. I have the time variable in one variable. Please and I will be very thankful for your help.

If you use MFC, you can use the CFile Class.Open,Close or Write Class Members are there. If you want a File Dialog you can use CFileDialog. Also there is the CStdioFile Class.
CStdioFile CalFile("YourFileName.dat",CFile::modeCreate | CFile::modeWrite | CFile::typeText );<br />
CalFile.WriteString(Time1.Format("%H,%M,%S"));
CalFile.WriteString("\n");
CalFile.WriteString(Time2.Format("%H,%M,%S"));<br />
CalFile.Close();

I'm new to programming.I received some code: the aim is that the commands are send with the socket-method, and then execute a console program, using the pipe-method. The code is rather long, so here is the fragment with the fault. I tried the following code : (with the aim to find the entire string that I typed in 'char kk', so I could compare it with another string like "help" or "howlong"...)
//////
{
long lEvent=WSAGETSELECTEVENT(lParam);
UINT r;
static char buf[MAXRECVBUF];
DWORD dwNumberOfBytesWrite;
SOCKET sock_tmp;
if (lEvent==FD_ACCEPT){
// "Accept" handler
SOCKADDR_IN clientAddr;
int nClientAddrLen=sizeof(clientAddr);
// Accept connection
if ((sock_tmp=accept(sock_listen,(LPSOCKADDR)&clientAddr,&nClientAddrLen))==INVALID_SOCKET){
if (WSAGetLastError()!=WSAEWOULDBLOCK) return;
}
if (NowUsing==TRUE){
closesocket(sock_tmp);
return;
}
sock=sock_tmp;
send(sock,BANNER,strlen(BANNER),0);
NowUsing=TRUE;
// Boot shell program
sa.nLength = sizeof(sa);
sa.bInheritHandle = TRUE;
sa.lpSecurityDescriptor = NULL;
CreatePipe(&hPipeOutputRead,&hPipeOutputWrite,&sa,5000);
CreatePipe(&hPipeInputRead,&hPipeInputWrite,&sa,5000);
memset((void *)&si,0,sizeof(si));
memset((void *)&pi,0,sizeof(pi));
si.cb = sizeof(si);
si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
si.wShowWindow = SW_SHOW;
si.hStdInput = hPipeInputRead;
si.hStdOutput = hPipeOutputWrite;
si.hStdError = hPipeOutputWrite;
CreateProcess (NULL,SHELL_NAME,NULL,NULL,TRUE,0,NULL,START_DIR,&si,&pi);
CloseHandle(hPipeOutputWrite);
CloseHandle(hPipeInputRead);
// Create character read&send thread
hThread_out = CreateThread(NULL,0,OutputToSocket ,NULL,0,&dwChildThreadIdOut);
return;
}else if (lEvent==FD_CLOSE){
// "Close" handler
closesocket(sock);
TerminateProcess(pi.hProcess,0);
TerminateThread(hThread_out,0);
CloseHandle(pi.hProcess);
CloseHandle(hPipeOutputRead);
CloseHandle(hPipeInputWrite);
NowUsing=FALSE;
return;
}
/////start problem-code//////
// Recv packet from client and write to SERVER.EXE
if ((r=recv(sock,(LPSTR)buf,MAXRECVBUF,0))==SOCKET_ERROR) {return;}
kk[i]=buf[0];
kk[i+1]='\0';
MessageBox(NULL,kk,"speciale functie uploaden en zo",MB_OK);
i=i+1;
WriteFile(hPipeInputWrite,&buf,r,&dwNumberOfBytesWrite,NULL);
/////end problem-code//////
}
/////
But now the messagebox always returns:
when I type the 1st character: the first character
when I type the 2nd character: the first character is now a trash character and the second is the character I typed
when I type the 3rd character: the first two character's are now trash character's and the third is the character I typed
...
What should I do so that I can find only the string I typed in "kk", without the trash??

Hi,
In my app I have to put some bitmamps in RichEditCtrls as Ole Objects. I load the bitmaps at the start of the application and I use OleCreateFromFile to create the object from the bitmap file.
The problem that I have is there are too many images (over 25) and the loading process takes about 7 seconds. If I load them in the main thread, the applications seems dead. You can't move the window, can't minimize it...
I tried to load the images in a separate thread but with the same code the OleCreateFromFile returns an error: "The system cannot find the specified file" altough if I make an fopen in the same thread I can read that file.
Do you know something about this? Am I doing something wrong?
Thanks

Does it not load, or does it load, run and close so quickly you can't see it? I've sometimes found this when there is an error in the initialisation code that causes the application to close before it does anything.
Hopes this helps,

Is there a way in MFC to control the background color of each item in a listbox. I've seen some custom controls that will do it but I would just like to use the standard listbox.

No, not without doing an ownerdraw listbox. There are examples here on CP.

Hi,
Thank you for checking out my post.
I am writing a simple CPropertySheet (with property pages of course) VC++ 6 Doc/View application, and I want to change the look of the OK or CANCEL buttons.
Trouble is that I don't seem to be able to create a control variable of either buttons. The buttons are provided by the framework I am thinking, but does anyone know how to access them?
The only interaction I have with the Cancel or OK buttons is to check the return value when dlg.DoModal() returns and that is it.
Thanks for any suggestions.
Michael

In the property sheet class, you can call GetDlgItem(IDOK) to get a CWnd* on the OK button. Change IDOK to IDCANCEL for the Cancel button.

Hi Mike,
Thank you so much for replying. I seem to recognize your name...I think you have kindly helped me in the past.
Anyway, I did try GetDlgItem(ID_OK) before I posted my question and I couldn't get it to work. It must be the way I did it. It would compile ok but crash on running when doing the check "ASSERT(::IsWindow(m_hWnd));". Here's the code I used within my CPropertySheet class's constructor :-
CMyPropertySheet::CMyPropertySheet(LPCTSTR pszCaption,
CWnd* pParentWnd, UINT iSelectPage)
:CPropertySheet(pszCaption, pParentWnd, iSelectPage)
{
//add each page to the propert sheet
this->AddPage(&this->m_prop_page1);
//get pointer to OK button so I can alter it
CButton * pbutton = (CButton *)this->GetDlgItem(IDOK);
}
Actually, as I write this I realize that maybe the propertySheet is not a window (and that includes the OK button) until I run "property_sheet_obj.DoModal()", so that might be the problem right there. Do I have to alter the OK button after the DoModal().....I will try that.
Thanks Mike and thank you all for any suggestions or confirmation.
Michael

No windows are created until after DoModal(), so it might be easiest to do the change in the first page that gets shown:
CPropertySheet* pSheet = (CPropertySheet*) GetParent();
CWnd* pOKBtn = pSheet->GetDlgItem(IDOK);
pOKBtn->SetWindowText ( _T("'Aight") );

I'm about to create a Word like replacement for my self, Word doesn't have CD-R burning features/XML format/Templates (HTML)/portiblility from comp to comp that i need so I'm going to make a replacement. Possibly if it is built right I'll sell copies. To start out how should I CFormView or CRichEdit?
Also I'm courious about how to include an Intelisense Like feature in a RichEdit/Edit box.

Nope, I've had a teacher that specifily requested Arial font, 1inch margins, specific headers etc. and my other teachers hated format. Instead of modifing the default and going against it, used XML and my CMS (ltpb.8m.com/XMLHTML[^]) and it worked well, I can take all of my work from the year on a floppy disk, including the data, templates (which preserve the formating) and programs I can use it almost anywhere. Also computers at school are a niche for macro and other viruses. Plus, I don't want to have to bother with O97/2k/2k3 incompatibilities.

I'm not sure you realize what you're proposing. Word required hundreds of developers and years to create.
If you wish to use MFC, the proper way to start is not with CFormView or CRichEdit -- but with CWnd (doing everything from scratch). I seriously doubt that Edit or RichEdit controls would be modifiable to do what you want.
A couple suggestions:
- IE provides a DHTML Editor.
- OpenOffice[^] -- has a Word clone with cross platform source.
Perhaps one or the other could be modified to do what you want.

Who ever thinks they can get a word processor is really high on something cause you would have alot of time and man power. You could just make a program like notepad but wordpad would still be hard to do. []_.(()).[]_.
