I am a beginner using Visual C++ and MFC. I have made a dialog-based application and want the program to quit when i click on a quit button. How do I write a quit function?
Thanks

if you look at the generated code from appwizard you will see that the DoModal() function returns to the app with either an IDOK or an IDCANCEL value and then exits ... just let one of your buttons exit the modal dialog code with a return value (anything you want really) and it will close the dialog app
elsewise you could post a WM_CLOSE message
mostly watching the human race is like watching dogs watch tv ... they see the pictures move but the meaning escapes them

You can also call OnOK or OnCancel. The difference is in the value returned from your dialogs DoModal call. You might even try EndModalLoop if you want to get fancy, but that would be unusual.

How I can add my text to the title text on the Main Frame ?
For example:
- My application name is "My_Program"
- I have project in this application - "Project_1" //like vc project
- I want than would be next: "My_program - Project_1"
- A project associate with some date (Not only with document) i.e. even all doc/view is closed
the project may be open. (Until a command -"close project").
thx.

To set your window's text, use.... SetWindowText("blah blah"); Do this in your CMainFrame, when-ever you want it to change, to whatever you like.

One can also use the OnShowWindow function to track with, each doc comes in and out of view. Then you can use the SetWindowText to change from xxx - Project 1 to xxx - Project n...

Hi,
I want to launch Direct Cable connection programmatically. Is there any API available for that? Can I use RAS API? RAS does not enumerate Serial Ports. Any help will be highly appreciated.
Thanks in advance.

CPaintDC dc(this);
HBITMAP hbitmap =
::LoadBitmap(::AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDB_TEST));
HDC hMemDC = ::CreateCompatibleDC(NULL);
SelectObject(hMemDC,hbitmap);
::StretchBlt(dc.m_hDC, 33, 22, 10, 3, hMemDC, 0, 0, 6, 6,SRCCOPY);
::DeleteDC(hMemDC);
::DeleteObject(hbitmap);
This paints a bitmap image on the dialog, but what about icons??? Can i change this code
so it paints a icon instead of a bitmap??? if so how??
Thank you..

If you look in your OnPaint for any dialog based app you may have written, you'll find this:
// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
So it would appear you can draw an icon into a DC and then stretch it into another, if you so desire.

Dear all,
I'm a junior developer writing mixed C/C++ based applications in Windows (using the VC++ command line tools, but not the DevStudio GUI). One of the question that I have the most trouble understanding is how does the build process really works. What is a precompiled header file? What's the difference between an .obj, a .dll, and a .lib file? How is an export table defined? How do a link all the .lib and .dll file together to make an executable? In many occasions it takes much more time finding out how to build and link properly than the actual coding part. I'm sure there are a lot more questions of this kind that are alluding junior developers everyday, since no good books are available and websites on the Internet (like CodeProject) rarely mentions anything on this subject. The MSDN website has a big chunk of reference manuals online about Compiling and Linking, but it offers almost little help for beginners who tries to learn this subject. Can anyone point me to some useful printed or Internet resources available? I'm hoping that someone in the CodeProject community can write an article on this subject too Thanks.

For a bit of a learning experience, try using the DevStudio GUI for a project and have a peek into the .DSP file (most of the commands for compile/link are there) or alternatively have the GUI export a makefile for you and inspect that one instead. It won't answer all your questions, but it should answer some of them.

I have developed a keyboard for the screen, but I need to send the keystrokes
to the application like MS Word. Right now the keyboard is in a floating window
capturing the mouse input but I want to send keystrokes to the other application,
ie. have another application capture the keystrokes even though it does not have
focus.
Is there a way of having the keyboard on top, getting mouse events but not taking
focus?
How do I send keyboard events to another application/window?
Please email me...dostie@nettaxi.com
THANKS!

Hi All,
I have to implement an SNMP extention Agent in W2000. It is based on a DLL which will be loaded by SNMP Agent. This DLL must communicate with a 16 bit APP to update the MIB handled by the DLL. I used :
- SendMessage() to communicate from the DLL to the 16 bit App.
- Generic thunk to invoke the DLL from the 16 bit App.
My problem is :
When I start the service SNMP in dos command by "snmp.exe" all is all right. But if I start the service by "net start snmp" the two process (DLL and 16 bit app) don't communicate. (FindWindow() to use with SendMessage() return WND=NULL and Generic thunk (CallProc32W()) crashs the 16 bit App and even Visual 1.52)
To make the Generic Thunk and FindWindow() work, it seems that the service must be attached to a window 
Someone with an idea ? 
Thanks for yor HELP

Yes, I don't think you'll be able to use FindWindow - the windows reside on two different 'desktops' for want of a better model.
One idea for communicating with services is for both the DLL and the .exe to use a socket to communicate - probably a simple UDP setup is all you need. Use the loopback (localhost 127.0.0.1) for the address for the sendto, and pick a couple of unused ports to bind to.
A nice touch would be using async sockets, so your app and DLL aren't polling.

Hi All,
Been stuck with this problem for quite sometime now, tried some other discussion group - no help, hope someone here can help me....
I would like to launch a CMiniFrameWnd/CDocument/CView derived objects from a Dialog based program (Doc/View was not selected during AppWizard).This window is a floating window above MyDialog and contains all the built-in Doc/View architecture when launched. This is what I have done up to now:-
BOOL CTestApp::InitInstance()
{
Other stuffs.....
CSingleDoctemplate* pDocTemplate;
pDocTemplate=new CSingleDocTemplate(
IDR_MINIFRAME, // I also have a problem understanding the string
// resource needed for this value here, no menu,
// no icon
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMyMiniFrame),
RUNTIME_CLASS(CMyView));
AddDocTemplate(pDocTemplate);
CMyDlg dlg;
int nResponse=dlg.DoModal();
etc etc
}
void CMyDlg::OnButton1()
{
// Here is where I would like to launch my floating Doc/View Frame
// I have no idea how to do it......
}
Thanks For any help

given that a dialog will by default be modal it will have the focus of your app until it closes ... to launch another dialog would be trivial ... launching a non-modal window would be like launching a modeless dialog as far as i can tell ... you would have to post a message to the modeless window if the modal dialog closed
also if you didn't include doc/view support during appwizard phase a lot of support code will not be included so as far as i can see you'll be doing a lot of work to get it done ... can you not structure your app differently to make life easier?

Installation of my machine:
-Visual C++ 6.0 enterprise edition
-Service Pack 4
-Processor Pack from Microsoft (ISSE, SSE2 support)
(-Windows 98 SE
-MSDN library
-Visual Source Safe 6.0)
Every time is start debugging on my machine with VC++6.0 debugger, I get an completely empty call stack window.
This happens always, and independantly of the project I want to debug. I have uninstalled/reinstalled VC++6.0 already,
but without success. Does anyone have a good tip for me?
|
|
|
|
|
I'll take Processor Pack for 200.
Seems to me it installs some updated DLLs - if these don't come with the same sym tables or pdbs as the regular VC stuff, that might kill the call trace.
Not sure, but have you tried uninstalling/reinstalling VC without the PP?
|
|
|
|
|
Yes, I already have tried uninstallig and reinstalling everything. I also have tired debug mode and the call stack
without the service packs and the PP - with no success.
Anyway I don't think that the PP is the problem: I have another machine configured the same, and on this everything runs well:
VC++ 6.0, Service Pack 4, PP, call stack works properly in debug mode...
I use the first machine to edit and compile the code (Win98 SE) and the second machine (Win 2000 professional) via remote debugging over LAN (TCP/IP)
tu run and test the code. But this should'nt be the reason for my problems, cause I have had this call stack problems already before using this remote
debugging combination.
