If the problem is that you get some error-messages about missing modules, you just need to locate the .dll:s missing and copy them to the new computer (like you do with the VB runtime).

Use the depends app, that application will say you the depends of your application, the dll that you need. You need to take care because some dll are in the operating system, and other can be in a old version....

Use the heap instead of the stack. Did you have a fonction using a array define on the stack like:

void myfunction(tatata)
{
DWORD data[1024]; // 1024*4 bytes allocated on the stack
DWORD *pdata = new DWORD[1024]; // 1024*4 bytes allocated on the heap

....
}

Does that help?

Use the debugger.

Run your program inside the debugger and before it gets to the stack overflow, open the Debug/Exceptions box and look for the "Stack Overflow" exception. Click on the "Stop always" radio button and then OK. Continue running. When the stack overflow occurs, the program will stop at the point where it's happening. That should give you a clue as to why it's happening and you can then fix it.

Good luck,

Urgent! Problem with MSWord component!

I use MSWord component in my project. I create a new MSWord document with name such as "d:\temp\mydoc1.doc" from template (example mytempate.dot). This template contain a macro to insert a text into document.

It runs OK even there are some MSWord applications (instances) currently open unless "mydoc1.doc"

Please see these codes:

int ret = NO_ERR;
CString strMacroName;
CStringList argList;

strMacroName = _T("LC_WriteText");
argList.AddHead("This is a text");

ret = CallMacro(strMacroName,&argList);

........

int CExportMSWord::CallMacro(CString& strMacroName, CStringList* pArgList)
{
int bRetVal = NO_ERR;
HRESULT hr = S_OK;
ASSERT(m_pWrdDoc != NULL && m_pWrdDoc->m_lpDispatch != NULL);

OLECHAR FAR* strMacro = strMacroName.AllocSysString();
DISPID dispid;

// Error occurs here
hr = m_pWrdDoc->m_lpDispatch->GetIDsOfNames(IID_NULL, &strMacro, 1, LOCALE_SYSTEM_DEFAULT, &dispid);
SysFreeString(strMacro);
if (FAILED(hr))
bRetVal = UNABLE_CALL_MACRO;

//Some codes....

}

Now I create a new document (mydoc2.doc) from template.dot. Initialize MSWord OK! Create new document OK.

When there is a document which was created from mytemplate.dot (mydoc1.doc) currently open, after executing CallMacro, hr = DISP_E_UNKNOWNNAME!

But if I close "mydoc1.doc", execute again, CallMacro runs OK (hr = S_OK).

Could you tell me what problem and how to fix it??

Thanks in advance
Tuy Le

Hi,

I'm running on a project, which reuse MS Office component, too
In fact, I still don't understand your problem, but I let you know some issues I have faced Smile | :)

1. The Worf instance you automated will be the same with another instance user run after your application started up, and supprise, it will be visible on screen !!!
2. In fact, Office applications is buggy when you manipulate them via automation, one of the most nasty bug I've faced is it conflict with NAV 2k

MFC DLL : linking error with message map

10-Dec-01 19:40

Hello,

I have a problem with DLL that I can't solve. I'm working on a quite important projects, with a lot of interfaces sharing several controls.
I want to make a DLL, Project_IHM.dll, containing common parts of the interface with a CGeneric_Dlg class, inherited from CDialog_Dlg in it.
This class is exported trhough the AFX_EXT_CLASS macro.
Then, in another DLL, I create classes inheriting from CGeneric_Dlg. Everything works perfectly, except the message map. If I use
BEGIN_MESSAGE_MAP(CMyDialog_Dlg, CGeneric_Dlg),
I got the following error
unresolved external symbol "protected: static struct AFX_MSGMAP const CGeoConcept_Dlg::messageMap" (?messageMap@CGeoConcept_Dlg@@1UAFX_MSGMAP@@B)
The only way I have found is to use
BEGIN_MESSAGE_MAP(CMyDialog_Dlg, CDialog_Dlg),
and add in the message map all the message that currently exists in CGeneric_Dlg.
It works, but it is not very nice.

How can I properly export the message map of my DLL?

If I understand your problem correct you have one MFC extension dll from which you export CGeneric_Dlg, and another MFC extension dll where you uose CGeneric_Dlg, right? If so, this will give you problems with AFX_EXT_CLASS. It will be evaluated to __declspec(dllexport) in both dlls, also the one where you want to import CGeneric_Dlg.

The standard solution is to use your own macro, like EXPORT_CGENERIC_DLG. Define it this way:

#if defined _COMPILING_PROJECT_IHM_DLL
#define EXPORT_CGENERIC_DLG __declspec(dllexport)
#else
#define EXPORT_CGENERIC_DLG __declspec(dllimport)
#endif

class EXPORT_CGENERIC_DLG CGeneric_Dlg : public CDialog_Dlg
{
// bla bla bla
}

Put _COMPILING_PROJECT_IMH_DLL as a defined symbol in the project settings of your Project_IMH.dll project, and *dont* put it in the dll that uses CGeneric_Dlg and you should be safe home!

Cheers
Steen.

I want to develop a client-server application. In my opinion this application would consist of WinNT service and GUI client program. Please help in which way I should manage and control WinNT service program from my GUI client program and visa versa. I need not in detail explanation but show me where I can start from?

I see

But I didn't find any answer to my question there. I need not WinNT with GUI interface, in contrary I need TWO processes. First one is a WinNT service and second one is a GUI program to manage first. Also this interacting should be double sided in order to service was be able to notify GUI program about its state. Sorry if I can mistake but I've really find not answer in topic being advised. Sorry again if I am silly Smile | :)

At such case give me exact link please.

Hello Morozov

Well I havent had to write such an application so far. In fact I have never ever written an NT service. Frown | :-(

But I might have to, soon.

I'd suggest this, perhaps it's a silly suggestion.

Have an admin port. Say you keep port 20000 open and the GUI client can connect to this port and send commands to the server [runnin as an NT service]. An advantage would be, now your service can be remotely controlled.

You can require authentication for connecting to this port thus making it kinda secure

If you make your service a COM server (which the ATL Wizard can generate), you can then get your client program to interact with the service via COM. I have used this method when both the client and server apps reside on the same machine.

Passing by reference means that any changes to the variable in the function effect the variable that was passed into the function, just like a pointer. Unlike a pointer, a reference is a value, not a memory address.

Ooops - I just saw where the reference is. Yes, because this variable remains in scope, it means that the variable you get back IS the variable in the array, not just the value of that variable.

Michael Dunn10-Dec-01 16:41

The difference is that the first version has a non-const this pointer, so the returned value is a reference to an array value. That means you can change the contents of the Matrix, such as:

void f ( Matrix& m )
{
  m(2,5) = 3.14;  // calls double& Matrix::operator()
}

But in the second, this is const, thus the return value cannot reference the object. So this code is illegal:

void g ( const Matrix& m )
{
  m(4,1) = 42;  // calls double Matrix::operator() const
                     // error, can't assign to a plain double
}

How can I make address of a member-function (__cdecl *)???

10-Dec-01 9:39

One function accepts an address of another as a parameter, I want to use a member-function of a class as the parameter, but I have this error: cannot convert parameter 1 from 'void (void)' to 'int (__cdecl *)(void)'

There's an example (MVSC++6) (Compilation gives the error)

typedef void(*fntFunc)();

class CMy
{
public:
CMy(){};
~CMy(){};
void Func();
};

void CMy::Func(){}

void CallIt(fntFunc fn)
{
fn();
}

int main(int argc, char* argv[])
{
CMy my;
CallIt(my.Func);
}
