From what I know, you cannot. The compiler needs to know if the function you are calling is included in the file.
One solution to overcome the problem of including both the *.h and the *.cpp files in your project is to use an interface for your class: you just make your class inherits from a pure abstract class (a class that has no member variables and whose functions needs to be redefined in the child class). Something like:
class MyInterface<br />
{<br />
<br />
void Method1() = 0;<br />
void Method2() = 0;<br />
....<br />
}
And in a separate file, you define your class that inherits of MyInterface:
class MyClass : public MyInterface<br />
{<br />
void Method1();<br />
void Method2();<br />
}
And the functions arre defined in the cpp file of the class.
So like that you only need to provide the .h file of the interface to your program and your program will only use a pointer to the interface. But inside the dll, when you create the pointer, you create in fact the child class.
Hope this helps

There is a function that checks for white space in a string called
isspace(int nTest)
Is there a similiar type function that looks for a "\n"?
I am trying to insert a \r before every instance of \n in an std::string
|
|
|
|
|
isspace tests for spaces (' '), tabs ('\t') and new lines ('\n')...
why not using std::string::replace("\n", "\r\n") ?

That sounds like what i need. Was not aware of that.
What would the syntax look like for this?
I have
std::string Response;
//Response has large amount of text with many "\n"'s
Response.replace ("\n","\r\n"); i get an error 2661 on this line
//The above line should parse throuh and replace all occurrances of \n with \r\n right.

Hello,
I am developing an application where I need to load custom data to Analysis Server (MS-OLAP) without going through any OLE DB Provider.
I am able to load data into dimensions/cubes using Microsoft OLE DB provider for ODBC Drivers. But my requirement is loading data at runtime from a buffer. Is there any way to do this? Are there any APIs which can help me to load this data directly?
Thanks & regards,
kuldeep kumar

I am aware of the general causes for access violation.
Please suggest....at the earliest...

This type error generally come when you try to write on unintialised Pointers

Hi,
I am thinking about installing DirectX9 SDK, but I am affraid about the performance impact.
I suppose the SDK comme will some "debug feature enabled" versions of DirectX libs.
Will those libs be used by commercial applications (i.e. games) instead of the normal end user ones and will it impact speed or stability ?
I am using Visual C++ 6.0 (SP6) on XP Home SP2.
Thanks for your advices/tips,
Th.

Perhaps you may re-install single user DirectX after the SDK?

After checking, it seems that you have a choice in DirectX control panel applet to use retail or debug versions.
Be aware that there are settings for many modules (Direct Input, D3D, ...).
But... (you'll hate me  ) after setting everything to "retail" I ran DiagFX whichfire me a warning about the fact I used a lib (only one) indebug mode and that it may be slower...
My advice: Use a different computer for coding and playing
Beside your issue, it is always tempting to use beta untested features on a development computer, and most very optimised games do not like this !
Good luck,
Eric

I've got a Visual Studio C++ 6.0 project which I am now trying to get working in VC++ .NET. I've encountered a problem with some file handling code which originally used <fstream.h>, I've changed this to use <fstream> however I am now encountering compilation errors when I'm accessing the file, e.g.
fileA.seekg ( EIGHTWORDS, ios::seek_dir::cur ) ;
it complains about the ios::seek_dir::cur part. Does anyone know what the equivelent 'flag' is in .NET and also where I can get a list of all other flags (MSDN doesn't seem to be much use on this)
TIA,
Andy

what is the error message ?
did you try prefixing with std:: ?

Thanks for your reply, the exact message I get is:
"error C2510 : 'seek_dir' : left of '::' must be a class/struct/union"
I've tried putting std before it but that has no effect.
|
|
|
|
|
looking at the MSDN[^], you should use ios::cur directly...
the error message tells you that you apply the operator :: to a non object identifier (seek_dir is not a class but an enum)...

Hi All
I used Windows management Instrumentation, registry access (used RegOpenKeyEx etc.) , & few APIs to build an application.
Now problem is that when i run the program then after 5-10 minutes dialog box(of exe) disappeares automatically.
What should I do to prevent this problem.
Please reply ..
Thanks & Regards.

I've never found such an strange behavior like that. Do you have any piece of code candidate that we could take a look?

Information related to program are as as follows
1) Program is written in VC++ 6.0.
2) WMI Classes for retrieving system hardware & software Inforamation.
3) Used Registry keys for information retrieval,(here I used RegOpenKeyEx(),RegEnumVale(), RegEnumKey() etc.)
4) Used some APIs for information retrieva(like OS Version, Computer Name, Number of processors etc.)
5) All the property pages are added to sheet in OnInitDialog() function.
6) Also everything is written in OnInitDialog().
7) For every resource(S/W or H/W) a linked list is created .
8) node of Linked list is structure whose attributes are TCHAR and _bstr_t type
9)structures contains all the information retrieved by either WMI, or by Registry or by APIs.
10) Finally values are displayed on property pages through structures.
* I have checked task manager there is no instance of program after termination.
* Time span is not more than 10 mins.
*Program is even terminated when i am continually clicking on varios controls, and tabs of dialog box.
*Also program is even terminated when there are no activities being done on the PC
Please reply .
Thanks

You'll have to Debug and put several breakoints over the app to know where can it be the problem. You also can write a log file a write it in severela points of the applications where you suspect that there's the problem.
