The installation does it automatically 
Seriously, make sure VS.NET is closed while you install the SDK, and you will have DX options in your new project options. If 9.0 supports managed code, the install does not without a command line switch when you run it - I think it's -manageddx, but that's from very vague memory.

I looking through the projects options but im not seeing it, can you tell me the exact location of the DX project template?
|
|
|
|
|
I don't seem to have it installed anymore. Did you take my advice, uninstall, close the IDE and reinstall ?

As a new Visual C++ programmer, I keep seeing examples of WriteLine with an 'S' preceding a literal string. What's that for?
|
|
|
|
|
There are many ways for a string to be represented in memory, I've only seen L next to a string to make it wide, but S would have to do something similar.
It's kind of hard to google for S

Read the numbers in, and then write them out to a new file as numbers. I'm not sure how to do that using CFile, but with an IOStream you could just pass them in.
CFile is really crap BTW, you should look into iostreams as a far better alternative.

I wrote a console application in Windows XP Visual C++ 6.0 and sent it to someone running Windows 2000 but it wouldn't run. An error box poped up saying The dynamix link library MFC4rD.DLL could not be found in ...
Is this a known problem? Is there any hope for me?

You sent the person a debug build (which requires MFC42D.dll). Rebuild the application in release mode and ship that version (which will require MFC42.dll, which in all likelihood already exists on their system).

An an aside to Ravi's recommendation, if you switch the project to use MFC in a static library, you won't need to ship any MFC DLLs at all.

Thank you both for your help.

Hi there,
I need to delete the Options menu during run-time. Currently it deletes it when the application first starts up. Then as I open up other CMultiDocTemplate windows, it reappears. These are the two functions I have in the CMainFrame class. I called the OnChangeFileMenu() function within the application class in InitInstance(). I thought that would do the trick but somehow it reappears as I open up other modal windows.
void CMainFrame::OnChangeFileMenu()
{
CWnd* pMain = AfxGetMainWnd();
// Get the menu from the application window.
CMenu* mmenu = pMain->GetMenu();
int pos = FindMenuItem(mmenu, "&Options");
if (pos > -1)
mmenu->RemoveMenu(pos, MF_BYPOSITION);
pMain->DrawMenuBar();
}
int CMainFrame::FindMenuItem(CMenu *menu, LPCTSTR menustr)
{
ASSERT(menu);
ASSERT(::IsMenu(menu->GetSafeHmenu()));
int count = menu->GetMenuItemCount();
for (int i = 0; i < count; i++)
{
CString str;
if (menu->GetMenuString(i, str, MF_BYPOSITION) &&
(strcmp(str, menustr) == 0))
return i;
}
return -1;
}
Besides inserting the below code in InitInstance, I also included it in the document view class's OnInitialUpdate:
// Get MDI Frame window
CMainFrame* pMainFrame = (CMainFrame*)AfxGetMainWnd();
#ifdef MODE_1
pMainFrame->OnChangeFileMenu();
#endif
That did the trick for only one document view class but not others. It does not detect the presence of the menu when it's called yet it reappears afterwards. How can I remove it completely without having to insert the above code in numerous places. It should have taken care of it in InitInstance(). Thanks.

I had a similar issue, but I took care of it by only having one menu. When no document is loaded,
a lot of the menu items are gray... But my application only deals with one type of document, so
that solution may not be suitable for you.
Iain.

I was trying to avoid having to create a second menu with the item removed but in the end I chose that route. So in InitInstance, one of the menus will appear according to my criteria. Thanks for responding though.

I am trying to hook to a process.
i use "CreateProcess" method to create process as WinWord.exe, MSPaint.exe
etc....
then i use a hooking (using SetWindowsHookEx method) with the call
WH_CBT and in the proc i try to catch HCBT_CREATEWND and see if it is the main window.....
this all means that i need to hook the creation of the process i have just created and retrieve a handle HWND to its main window
it works ok with MSPaint but for word and excel and power point for example, it don't work at all....it seems that the hook occurs right after the main window was already created that is why the message WM_CREATE never cought....
can any1 help?
am i doing it wrong? is there a better way?
10x in advanced

Im using MFC to make dailog based program.
I have one button that will change my start button text to "TEST" after click.
my program crash after I clicked on the button
here is the code for the button.
void CStart_Button_ChangerDlg::OnText()
{
HWND starthandle;
CWnd StartButton;
CWnd* Window = CWnd::FindWindow("Shell_TrayWnd","");
starthandle = FindWindowEx(NULL,NULL,"Button","");
StartButton.m_hWnd=starthandle;
StartButton.SetWindowText("TEST");
StartButton.SendMessage(WM_SETTEXT,0,0);
//SendMessage (StartButton, WM_SETTEXT, 0);

See here on how to do this.
Mouse_103 wrote:

StartButton.SetWindowText("TEST");
Should be:
starthandle = FindWindowEx(Window->GetSafeHwnd(),NULL,"Button",NULL);
::SetWindowText(starthandle, "TEST"); However, this will not work as intended as the Start button's text is not drawn in the normal fashion.

The compiler is telling you exactly what the problem is. You are trying to use CWnd::SetWindowText() which does not take 2 parameters.
