Hi,
I'm working with a C++ project and have created a new .h file that contains typedef of new types. How do I use the new types in another class?
#ifndef COMMONSETTINGS_H_
#define COMMONSETTINGS_H_
typedef enum
{
XX = 0,
YY,
ZZ
} ProductType;
#endif /* COMMONSETTINGS_H_ */
And the class that uses the type ProductType
class TestClass
{
public:
TestClass();
virtual ~TestClass();
private:
ProductType product;
};
How do I do to use ProductTyp in TestClass? Now I get compile erro since TestClass can not find ProductType.
What is the best way to solve this? I want to declare new types in a file and use the types in several other classes.

Stupid question, but did you #include the header file in your compilation unit?

Enumerations did not need the typedef keyword. Use
enum ProductType
{
XX,
YY,
ZZ
};
You should also think about moving your common settings into those classes they are belonging to (e.g. the class that acts according to the ProductType enumeration). This is better C++ style and makes your code modules better portable to other projects.
To use such class specific enumerations from other classes, prefix them with the class name (e.g. MyClass::ProductType).

I use this solution, then it's working.

please include that headerfile..

I already include that header file

I read the UAC article on CodeProject. So I want to see what others are using to elevate when using CreateProcess on Windows Vista, maybe Windows 7, when I get to testing on it.
I'm using CreateProcess to run PkgMgr.exe, but it wants elevated privileges 740.
Plus I want to spawn 2 threads, one to run the progress bar, and one to run the CreateProcess.
Tried _beginThread, but I was only able to get 1 working at a time.

There shouldn't be any thread creating issues related to UAC... I use them all over the place, haven't had an issue, after all, they're all part of the same process... CreateProcess() I imagine does require the elevated privileges since you're spawning another process other than what the user selected to run.
|
|
|
|
|
I didn't think of it that way.
Perhaps I should get their credentials in a dialog box, and run CreateProcessWLogon.
ShellExecuteEx works, it's checks for permission, and goes, but is hard to track when it's done.
|
|
|
|
|
You could do it whatever way works best for you AND your user... for example, if you expect your average user to not have admin privileges on his machine, then you should probably avoid adding any code that's going to require admin level privileges (unless you absolutely have to).
|
|
|
|
|
I'm going to leave the code the way it is for now.
I ran CreateProcess first, and checked for an error, then used ShellExecute if error 740 comes up. I'll conduct more testing on Windows 7 and Server 2008 to see how it works out.
|

|
|
|
Good luck 
|
|
|
|

Didn't work out.
Any system changes requires a UAC elevation, so I went ahead and made a dialog box asking for credentials that I can pass to CreateProcess with Login. So I will play nice with UAC and adhere to the purpose of it. I just hope I get it right this time.
Now I can use the luck.

UAC is a pain in the butt... but ultimately, it's Windows trying to recreate the same, more secure, method of operations that's been used in a lot of Linux distros for a while now. Should mean security in the long run... headaches in the short term.

Hi All,
I want convert BIG integer value to string
for that i used
_strtoi64
that convert values still 9,223,372,036,854,775,807
but for big value greated than "9,223,372,036,854,775,807" it gives wrong value

You cannot convert values greater than the maximum allowed for a 64 bit integer.

You already got answers to your same question in the Quick Answers question at [^]

Either the title or your explanation is wrong. I guess you need to convert a string representing a very big number to, well, a big integer variable.
As Jochen pointed out, we already answered your question at QA.
However, if you really don't want to use a big integer library then may you roll you own version of, say, strtoi128, i.e. a function converting the given string into the 128 bit binary representation of the number (you may mimic the method used at school to perform division).

Thank you.
However, I realize it would be a bit difficult for a newbie.

Definitely... but it is worth noting that they can do it themselves if need be.

 Dear Friends
I am building an application as dll. Its building with 'no common language runtime support'. But if I build with 'common language runtime support (clr)' then its giving errors. Can u tell me whats going wrong.
Here are the errors 2 linking errors
[code]
Linking...

How did you create the project? I understand that you have created a native dll and enabling the clr option for the build and that is why the linker error. BTW why do you want to build the with clr enabled?
You talk about Being HUMAN. I have it in my name
