go to the resource editor, then check the SDI frame properties and search the caption...

you could also do it at run time with a little SetWindowText() on you main frame...

Right you are! And here I was thinking I'd have to override one of the CDocTemplate methods... I guess I over-thunk this one... lol...

Thanks!

Isn´t it just AfxGetMainWnd()->SetWindowText("MyApp")? Didn´t try, but it´s a suggestion...

Most folks use:

BOOL CMainFrame::PreCreateWindow( CREATESTRUCT &cs )
{
    cs.style &= ~FWS_ADDTOTITLE;
    return CFrameWnd::PreCreateWindow(cs);
}

Help to remove a level 4 warning

I'm at a loss for how to correct for a level 4 warning.

header file
void some_func(some_type *ptr, int flag);

source file
void some_func(some_type *ptr, int flag)
{
...
...
}

and when I compile, I get

warning C4100: 'flag' : unreferenced formal parameter

and yes 'flag' is an unreferenced parameter, so I make the following change

source file
void some_func(some_type *ptr, int /* flag */ )
{
...
...
}

and when I compile, I get

error C2055: expected formal parameter list, not a type list

I'm not sure how I have to change the source file, such that I don't get either the warning or the error. Thanks.

You could always do:

void some_func(some_type *ptr, int flag)
{
......

UNREFERENCED_PARAMETER(flag);
}

#pragma warning( push )
#pragma warning(disable:4100)
void some_func(some_type *ptr, int /* flag */ ){......}
#pragma warning(pop)

or...

Refactor your code so that the unused parameter is not passed to function in first place Wink | ;)

Assumption: 'ptr' or even (the real name for) 'some_type' is declared in a header file (from you or from Windows) and confuses the compiler.

what is alternation for "ODBCVER.H"of vc6.0 in vc7.0?
can any one please let me know this?
Previously I was using vc6.0;

Now I could not run my project. I am getting error as could not open the file "ODBCVER.H".

I think this file was included in VC6 by accident. It appears to contain data used when building the ODBC library (version information to be included in the file version resource data); I can't imagine what you're using this file for but it should not be necessary.

Better hook winsockX.dll to see actual command coming and going !

#define scope rules

Hi. I'm reading through some *very* old 'C' code that was created during the C89 standards - pre-1999. Basically, I've inherited some code from company A to support at company B.

Anyway, in one procedure I've located a #define that the original programmer quoted as it being local to the procedure.

Now, correct me if I'm wrong (of course you will! Laugh | :laugh:

); but, arn't #define's that are created anywhere in the code visible to the remaining portions of the project? That is, all remaining code, across files, that has yet to be compiled (from when the #define is declared) will contain the #define'd parameter until it is undefined?

Was there ever a difference in this behaviour between C89 and C99 conventions?

Thanks!

Carl

wow, i don't know at all about the old standard, but i never heard of a #define with a local scope...

[edit]
ok, misunderstood. yeah, the module end is limiting the scope of the preprocessor directives, but never a function body !

nope.

The preprocessor doesn't know about the scope rules of C. Preprocessor directives like #define take effect as soon as they are seen and remain in effect until the end of the file that contains them; the program's block structure is irrelevant.

I am writing a program for a Scoreboard that contains a SplitterWnd, the upper Window (ScoreboardWnd) displays the whole screen with (Period Time, Scores, .. etc). The lower window contains all the Input’s and Buttons to administrate the Scoreboard.

I now want to display only the ScoreboardWnd on another VGA screen (Full mode).
I have looked at the CMonitor class and tested it properly.

On a Laptop with a 2nd VGA out I connected a 2nd TFT screen to see how the program works.

Now a few questions: How can I display out from a SplitterWnd a window on the 2nd screen?
On the laptop the whole program should be displayed.
The program is made with VC 7.xx!

It would be great if you have a sample for such a case I described above. Great work by the way!

Thanks in advance
Best regards

Karl

CreateProcess doesn't work while ShellExecute Does!!!!

Hi all,

I want to run ACDSee from create process
this is the code i use:

STARTUPINFOW si;
PROCESS_INFORMATION pi;
ZeroMemory(&pi,sizeof(PROCESS_INFORMATION));
ZeroMemory(&si,sizeof(STARTUPINFO));
si.cb = sizeof(STARTUPINFOW);
si.wShowWindow = 1; // show
if(!CreateProcessW(L"C:\\Program Files\\ACD Systems\\ACDSee\\6.0\\ACDSee6.exe", 
		   L"C:\\Program Files\\ACD Systems\\ACDSee\\6.0\\ACDSee6.exe",
		   NULL,
		   NULL, 
		   FALSE, 
		   0,
		   NULL,
		   NULL,
		   &si,
		   &pi))
{
	ASSERT(FALSE);// failure
}

// success

ok , the above code seems ok, but the problem is i pass the create process sucessfully, and i can't see any ACDSEE window open (nor i can't see the process in the task manager)....

if i use this substitue code:

ShellExecuteW(NULL,
	  L"open",
	  L"C:\\Program Files\\ACD Systems\\ACDSee\\6.0\\ACDSee6.exe",
	  NULL,
	  NULL,
	  SW_SHOWNORMAL);

it is working ok and ACDSEE is opened.

i can't use ShellExecute because i need some process information which PROCESS_INFORMATION structure holds....

can any1 help?

thanks in advanced

Not sure if this will work but the second argument of CreateProcess is the commandline parameters that will be sent to the program. So, replace it by NULL and try again.
