Hi.
My application was designed for Win2000 only (I use DirectX 7). And I plan to detect attempt to run this on WinNT4 , because there is error message "The procedure entry point DirectDrawCreateEx could not be located in the dynamic link library DDRAW.dll, but this message show up before WinMain call.
Thanks for advise.

Afaik you can't run DirectX > 3 on Windows NT 4.0. ( Execute-buffers, you've got to love them...  )

I know this, but I need only valid error report, maybe like this:
"This program requiedWin98/2000 only" 
I need to detect OS version BEFORE the program say "...Entry Point for DirectDrawCreateEx was not found..."
I think that in DDRAW.dll in DllEntryPoint there is call of DirectDrawCreateEx and i have this error message before Step IN to WinMain

Oh, sorry, I see. You need to load the DLL manually, ( using LoadLibrary ), then.

As you have found, the OS loader is trying to bring in functions / dlls that aren't there.
There are two ways around this. Actually, they are effectively the same, but you do different
things.
1/ Delay load (e.g.) ddraw.dll and catch the DirectDrawCreateEx function failure with an exception
handler, or
2/ Explicitly load the function using LoadLibrary and GetProcAddress.

My problem is a simple one:
I have a dialog box. A simple one, just two lines to fill. If I press enter/return, by default dialog closes as if I have pressed ok.
I would like to capture the keyboard, and make my dialog move onto next items when enter is pressed.
I tried the following, no success:
void CEditDlg::OnKeyUp(UINT nChar, UINT nRepCnt, UINT nFlags) <br />
{<br />
AfxMessageBox("KEYUP");<br />
<br />
CDialog::OnKeyUp(nChar, nRepCnt, nFlags);<br />
}<br />
<br />
void CEditDlg::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags) <br />
{<br />
AfxMessageBox("CHAR");<br />
<br />
CDialog::OnChar(nChar, nRepCnt, nFlags);<br />
}

I forgot to check the dialog template in resource editor 
I just changed "Default button" propoerty from OK to "Insert" button.

Under Visual C++ NET the print preview in MFC can be performed only within the MDI child frame and not anymore within the main application frame as before. Does anybody know the way to get the former behavior?
Thanks!

Does any one know how we can reverse engineer MFC code in rational rose 2000? i've already gone through the help in rational rose and most of the stuff is outdated

HI,
I have to read the icons for different file types and display them .
Now if i load the common icons from a resource script it wont suffice .
as for a new/different file type it does not work . So it is obvious that
it has to be read from the registry . ( my application uses win32 api)
Any help will be appreciated.
thanks

Look up SHGetFileInfo in the Platform SDK.
As I remember, Paul diLascio (MSDN) did a series of C++Q&A articles on all this.

discovered another api .
ExractAssociatedIcon(also a shell api ) to do it .

Does anyone recognize this value? Would be very helpful right now...
I get an (rare) error condition where some buffers are filled with 0xFEEEFEEE. It could be a usual allocation problem (but the CRT Debug heap doesn't seem to use this), or from a call into a 3rd party library which in turn passes the buffer into a kernel mode driver.
TIA

The C libraries fill memory formerly occupied by an allocation with this pattern when
it is deleted.
So, you're trying to use a deleted block of memory.

hi
to draw a String with GDI+ :
graphics.DrawString(L"Hello", -1, &font, PointF(600,100), &solidBrush);
how can i change an integer to WCHAR in parameter 1.
for exmple i want to draw figures from 1 to 100.
thanx
|
|
|
|
|
char tmp[4];
for(int i = 1 ; i < 100 ; i++) {
sprintf(tmp, "%s", i);
graphics.DrawString(tmp, -1, &font, PointF(600,100), &solidBrush);
}
You can also use eg std::string and boost::lexical_cast, but this is the simplest form I guess

You obviously meant:-
sprintf(tmp, "%d", i);

Yes I did - shame on me

CString blub;
for (int i=0;i<100;i++)
{
blub.Format(L"%i",i);
graphics.DrawString(blub, -1, &font, PointF(600,100), &solidBrush);

How can i obtain the process handle of any process under execution ??? Actually, i am writing an application that can terminate any process. For this purpose i am using API TerminateProcess():
BOOL TerminateProcess(<br />
HANDLE hProcess,<br />
UINT uExitCode<br />
)
As can be seen from the syntax, the first argument is the process handle. How can i obtain this handle when i only know is the process name ???? Is there any other alternative you suggest me instead of TerminateProcess() ???

For this you need to look on the following API's
CreateToolhelp32Snapshot for a snapshot of running process on your machine and on successful exec. of this function you need to iterate the processes using Process32First followed by Process32Next.
Also look at the following API's in MSDN
GetProcessModule
OpenProcess
