or...
Refactor your code so that the unused parameter is not passed to function in first place

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.

#include "ODBCVER.H"
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 uninstalled the vc6.0 completely and Installed the vc7.0;
Now I could not run my project. I am getting error as could not open the file "ODBCVER.H".
Please help me.
Nice talking to you.

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.

Hi Mike,
Many thanks for giving the reply. Thanks for your suggestion. Now in my project I simply ignored this include statement. Now my project is working as usual. 
Nice talking to you.

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

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!  ); 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 !

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

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;
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);
}
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.

doesn't work....
any other suggestion? anyone else?
thanks

I'm not sure if this is what the problem is as everything else looks ok, according at MSDN if your using using the si.wShowWindow property you need to set si.dwFlags to STARTF_USESHOWWINDOW else it'll just ignore it.
Out of interest have you tried changing it to launch Word or something to check the code is working ok?

also tried it (the STARTF_USESHOWWINDOW ) and still not working...
I tried creating process of notepad.exe and it works 100%!!!
i think the problem is the environment while i create ACDSEE 6 process...because it works fine with ACDSEE 3....not sure why though....
any thought?
thanks again

Two potential reasons:
1) the lpCommandLine parameter of CreateProcessW() is the white-space delimited list of arguments passed as argv to the new process. If ACDSee expects to find the path to its own executable in argv[0] the above would fail, as your path contains whitespaces. Basically the result of the above would be: argv[0]="C:\Program", argv[1]="Files\ACD", argv[2]="Systems\ACDSee\6.0}ACDSee6.exe"
You should quote the string, e.g. pass it as:
L"\"C:\\Program Files\\ACD Systems\\ACDSee\\6.0\\ACDSee6.exe\""
2) The UNICODE-Version of CreateProcess() may fail on NT/2k/XP if the parameter passed as lpCommandLine points to a constant string. This is explicitly mentioned in MSDN. Note that the type is LPWSTR, not LPCWSTR. Maybe you should copy your string to a modifiable buffer and pass this buffer to CreateProcessW():
I usually pass NULL for the lpApplication parameter and only use lpCommandLine. Of course, you have to make sure that a path containing white-spaces is quoted in this case (as described above). ShellExecute() is intended to be more "user friendly", that is it applies some heuristics to resolve pathes containing white spaces and does other "magic stuff".
Hope that helps

Thanks for all the replies!
i've managed...the problem was that when creating acdsee6 process, you need to set up the acdsee environment (because it loads some dll that are located else where) so you can get the environment out of the registry and then use the 'SetEnvironmentVariable' method
this works 100%....
to discover that, i needed to hook the ShellExecute method, and learned that it calls CreateProcess behind the scenes, with the necessary paramters that one of them was the environment looking at the memroy of that variable, i've seen the acdsee directory reference (the one that the dll reside)...
so mission completed
thanks again

The only examples I have found are for VS C++ 6.0; e.g. Circle, Button, CIRC1/2/3 etc.
Are they any articles/tutorials for VS .Net as the Wizards hav gone on .Net

Is it possible to use the DeviceIoControl() function to send commands directly to the driver for a COM port?
I am developing a time sensitive serial port application where I periodically need to change the parity of my serial data. Calls to Get_Comm_State() & Set_Comm_State() to update the parity are taking too long. I observed (using a serial port monitor) that these get and set methods do alot of unnessecary things like seting the baud rate etc.
It would be nice if I could use the DeviceIoControl function along with the IOCTL_SERIAL_SET_LINE_CONTROL command (or similar) to quickly change the parity from within my application. Am I living in a fantasy world or is this a possibility?
Many thanks
