Hi,
I have created a dll which exports a factory function that returns an object
of the type of the dll class:
class CMyDll
{
Z();
X();
Y();
}
extern "c"
{
__declspec(dllexport) CMyDll* Factory();
}
The program that utilize the dll loads the dll calls the factory function and get the dll object. from that object i call the dll functions.
MyApp()
{
hmodule = AfxLoadLibrary(MyDll.dll);
typedef CMyDll* (*FACTORY )(void);
FACTORY pFunc;
pFunc = (FACTORY)GetProcAddress(hmodule,"Factory");
CMyDll *dllObj = pFunc();
dllObj->X();
dllObj->Y();
dllObj->Z();
}
But there is a problem , the functions are not called right, if i call
functions X,Y and Z, it calls functions Z,Y and X in a certain order which i
couldn't specify.
If someone spotted the source of the error please let me know
Thanks
Simon

what about this :
pFunc = (FACTORY)GetProcAddress(hmodule,"<code>_Factory</code>");
BTW, your code is not very secure, as you don't test hmodule before using it...

Where is the rest of the Factory() function, could be an allocation error.

Hi all, thanks for your answers.
The problem was that i declared a function in the interface as an int, but the implementing class declared the same function with an enum.
So when calling the function from the dll (which was the implementing class) the function was not found and another function was called.

I am not sure anyone here or anywhere else will help you. Can you give a good reason to want to do this? The implications of such a request is for nefarious purposes only. Unless you have a really good reason to want to do this, please post it, and then you might get help.
Somethings seem HARD to do, until we know how to do them.

Well, that has nothing to do with hiding it from the task manager. Take a look at this article[^] for instance.
Ans please, make an effort when you write because the only thing I understood from your post was that you want only one instance of your app, the rest was completely obscure to me.

IF you want tto hide your process of TaskManager or other programs my experience is no,you cant.

First, you cannot do something like that. Second, we do not support people to build applications of that kind.

Hi all,
I have this snippet:
TCHAR buff[1024] = {_T('\0')};
_tcscat(buff, _T("This is a test"));
UINT ii = 0;
ii = strlen(buff);
I get the error :
error C2664: 'strlen' : cannot convert parameter 1 from 'TCHAR [1024]' to 'const char *'
Now I am wondering why this compiles fine with the project i copied this snippet from.
If i use reinterpret cast the strlen only returns 1
Please advise
Thanks,
Jayjay

I guess in your project, UNICODE is defined and strlen() is not unicode compatible. Since your string is TCHAR array, you should use _tcslen().

In that project UNICODE might not be defined.

You have to use the unicode routine instead: _tcslen. I suggest this excelent article[^] if you want to understand things properly. It is a must read for each C++ developper.

How is it that you knew TCHAR required _T() and _tcscat(), but still tried to use strlen()?

Use the HtmlHelp function instead of ShellExecute, it takes care of that.
Really, I just checked in one of my apps that uses HtmlHelp function, and the help does in fact close when the app is terminated. I assume that you're using the code I posted?
