So is it a service then? If it's not any of those four, what type of Windows program are you trying to create?

well, thank you for interesting ,
any way if you have see the link ,and downloaded the source code , you may have better vision because i started programming in c++ from no more than one years ,and this is the first time that i want to do something like that,most of my program were no more than one or two C++ files and a header, this my programming background ,so i don't know how to explain more than that..
i really need help and advice to explain more..

Start by creating an empty Windows program (whether you opt for console or Win32 is up to you), then add to it those files you downloaded.

Hi every one, I'm not sure where should I ask my question,
I want a link or eBook which explain clips programming but with an expert system example step by step. not form the beginning. I have search the net but I couldn't find what I'm looking for.
I would be so thanks full if some one could help.

What is "clips programming"?
Use the best guess
|
|
|
|

I'm so sorry. what I mean is programming in Clips (C Language Integrated Production System) which is a Tools for expert system.

Thx,but I'm looking for sth which explain it by a simple expert system step by step.

Hi all,
I am capturing desktop by using BitBlt.
Without CAPTUREBLT, I can capture desktop without capturing layered windows in Windows XP.
In Windows Vista or Windows 7, there is a problem with this, but when I stop the Desktop Windows Manager service, this can be solved.
But in Windows 8, I cannot stop this service, so I must find another solution to capture the desktop screen without layered windows.
Can anybody give me an idea?
Thank you very much.

Hello,
We are running a boost unit test using command line (cmd). The command is:
C:\> /c "D:\MyExecutable.exe" --run_test=testcase1,testcase2,testcase3, --report_format=xml --report_level=detailed --log_format=xml --log_level=all >test_log.xml 2>test_report.xml
The output format is in XML.
I would like to have the call stack for the failed test cases. Is it possible to write the call stack trace in test_report.xml or test_log.xml ?
Is there any macro or Boost API can help me achieve this?

Hello,
I have observed that in native unit test framework(c++), there is an option to group test cases using attributes which are reflected as traits in the Test Explorer window in MS VS2012.
Following is a an example of the same:
BEGIN_TEST_METHOD_ATTRIBUTE(TestMethod3)
TEST_OWNER(L"SuperMan")
TEST_PRIORITY(2)
TEST_METHOD_ATTRIBUTE(L"Category",L"Slow")
END_TEST_METHOD_ATTRIBUTE()
TEST_METHOD(TestMethod3)
{
Assert::AreEqual(2,6);
}
How can this be achieved via Boost Unit Test Library? Are there macros to achieve the same?

I have a problem regarding file streams in Qt.
Basically, I read a file using this code:
int LoadSettings(){
QFile* settingsFile = new QFile(storageFileLocation);
if(!settingsFile->open(QIODevice::ReadOnly | QIODevice::Text)){
return SettingsStorage::ErrorReadingFile;
}
QTextStream settingsFileStream(settingsFile);
while(!settingsFileStream.atEnd()){
QString fileLine;
fileLine = settingsFileStream.readLine();
QStringList splittedSettings = fileLine.split(SETTING_NAME_VALUE_SEPARATOR);
int addingStatus = AddSettingIfNotExist(splittedSettings[SETTINGSARRAY_SETTINGNAMEPOS], splittedSettings[SETTINGSARRAY_SETTINGVALUEPOS]);
}
delete(settingsFile);
return SettingsStorage::Ok;
}
AFAIK I have to delete dynamically allocated memory myself. I dynamically allocate the QFile* "settingsFile" and want to delete it as soon as I do not need it anymore. So why do I get a memory access violation message?
I also know that Qt automatically disposes all allocated objects as soon as they derive from the QObject base class, but I want to write to the file later, therefore I have to clean up the allocated memory by myself.
Any help is greatly appreciated.

Are you sure that the problem is settingsFile? If QObjects really dispose themselves, maybe they assume to be allocated on the heap and give a problem than being allocated on the stack. Have you tried commtenting parts of the code out, especially the loop and the QTextStream?

Yes. And every other dynamically allocated object. I can allocate memory for an object, but not delete it.

Commented out the delete-part and everything was fine. Except that there was a memory leakage.

Why you are using "delete(settingsFile);" instead of "delete settingsFile;". What does it mean?
I think you should also close settings file before deleting it.
And if the settingsfile->open() fails you will get another memmory leaks, because you are leaving function without deleting settingsfile.

The same this as sizeof(var) and return(result). Parenthesis are optional.

Certainly looks like the entire code block is suspect to me.
You have something that looks like a file, which is scoped by new/delete. Then that gets used by something else, that looks like a file reader, and the scope of that is the method. Thus it continues to have a reference to the 'file' until the method exits even though you have already deleted it. Either both should be on the heap or neither should be.
And the first has a close method. Which, hopefully the dtor takes care of by certainly I never assume that.
You make a memory allocation and then do an error check and exit - without cleaning up.

I need to store a structure in a database..but the structure contains another structure..can anybody help me plz
|
|
|
|
|
Are you trying to store all this data in one database field or store its contents in separate fields? Please provide more details.
Use the best guess
|
|
|
|

Given that you have two structures, you need something like a foreign key to resolve them when loading them from database.
Given there is structure #1:
struct numberOne{
int childStructId,
int someValue
};
and struct #2:
struct numberTwo{
int id, int anotherValue
};
You need now a database which has two tables, one to store struct #1 and another one for struct #2:
The table for struct #1 has two fields, for the childStructId and onther one for someValue.
The table for struct #2 has also two fields, one for its unique Id and another one for anotherValue.
Afterwards you can load struct #1 from database, and according to the childStructId you can load struct #2 from the database.
I was just guessing what you want, please come back to me if you have further questions.

You can find an intro of how to connect to a SQLite database at the SQLite website[^].
The people of the Database forum[^] will help you to find out which tables you will need to create a reliable database.

You may create two tables where one contains a reference (foreign key) to the other:
TABLE example2
INT id unique ID, usually auto increment
INT value
TABLE example
INT id
VARCHAR name
INT id2 foreign key to access table example2
