I am guessing from your message that you just do not know where to start. I recommend you type 'serial port' in the Search box above and you will get plenty of articles to get you going.
Good Luck

hi all
iam working on WMI . iam trying to write an application for Event notification.
Iam usimg Win32_Process class, and ExecNotificationQuery for WQl query.
Iam trying to display a message when a new process is created.
my WQL query is
hres = pSvc->ExecNotificationQuery(
bstr_t("WQL"),
bstr_t("SELECT * FROM __InstanceCreationEvent WITHIN 5 WHERE TargetInstance ISA 'Win32_Process' And (TargetInstance.Name = 'notepad.exe' OR TargetInstance.Name = 'calc.exe' ) "),
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator);
if iam not wrong ,After executing this query TargetInstance will be Instance of WIn32_process class.
and now iam trying extract data usoing this statement
hr = pclsObj->Get(L("TargetInstance.Name"), 0, &vtProp, 0, 0);
but iam not able to get value of Name property of Win32_Process class into vtProp where vtProp is of type VARIANT.
IWbemClassObject->Get( LPCWSTR wszName,LONG lFlags, VARIANT* pVal,CIMTYPE* pvtType, LONG* plFlavor) is used to retrieves Specified property value.
but here iam using it for getting value fron an istance i.e TargetInstance.Name. Is it the correct way to do if not please help me in extracting value of Name Property.
Please help me in solving this .
Thanks in advance

How can I determine that the given name is a file or folder?
An option might be to use "fopen". looking at the returned values i can determine that its a file or folder,
But i do not want to use this technique because the file might be in use of an other process; which may cause shairing or other comlex problems.
Any programatic way to safely access the information in directory, because all file folders have entry there?
Thanks in advance ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

GetFileAttributes(...), GetFileAttributesEx(...) and SHGetFileInfo(...) will help you out here.

A whole-sales company requires a program that will help to print cheque like the one below:
Write a C++ program to perform the following:
- Input fields: NAME, IC NUMBER, AMOUNT

amount amount in words
-----------------------------------------
40.00 Forty only
123.00 One Hundred and Twenty Three only
2323.00 Two Thousands Three Hundred and Twenty Three only

Ok, but what error?
It happens during compile or when the program is running?
If it is a runtime error you can mark the program flow with markers like:
cout<<descriptionstring;
to know="" the="" value="" of="" some="" variables="" and="" where="" are="" you="" at="" before="" error.
or,="" better,="" use="" break-points="" on="" your="" c++="" editor="" if="" it="" has="" they.

Hi!
I had download the source code of mass storage device driver for windows98 from Microsoft websit.And builded it with 98ddk on windows98 system,and then
installed it on win98 system. It can work correctly all the time.
If I suddenly remove the device from pc when copying file from pc to device or from device to pc on win98 system,the blue screen occur,and i have to restart my system.
But if do the same on win2000 or winxp there is no blue screen.
Now i wanna modify the driver source code to avoid the blue screen when suddently remove the device while it is exchanging data with pc on win98 system.
My question is:
1,If my hope has the possibility to come true?
2,If has,then which part of source code of this drive should i have to modify,and what couses the blue screen?
I know that in the source code it just abort all the pipes when device remove sudently but nothing else.
Thanks!

Hi,
Is there any upgradation tool for migrating VC++ 6.0 code to VC++ 2005 code. This project in VC++ 6.0 has ATL and COM components.
Are there complete tutorial for this upgradation.
Is there any tool that upgrades atleast partially?
Any help in this regard is appreciated.
