How to add soap header information in a proxy class

6-Jun-07 1:23

Can you please mention in detail, which type of dll you are creating and what will be your client application.
Dll created using MFC is not very much flexible.

In you client application, add this string (#include "yourATLDLL.rc") in View->Resource Includes->Compile-time directives edit box.

Next, in Project Settings->Resources tab, under "Additional resource include directories:" edit box, add (..\foldername) where your "ATLDLL.rc" file is located.

Hope this helps.

Hi,

I have generated a webservice proxy code in c++ using SPROXY.exe tool.
Using this proxy code I call to webservice methods (written in Java). I can call the methods now but I am not able to send the authentication (username/pwd) information and hence the web service responds with error stating “Failed Authentication”.

How can I modify my proxy code so that I can send the authentication information in the SOAP header?

Do you want to prevent the user from entering characters as well?

If so, you can use the EM_SETREADONLY message.

Hi,
I guess the class wizard donot seem helpful for you.

Do it manually,

use ON_COMMAND macro in your message map of mainframe window class

 BEGIN_MESSAGE_MAP(CYourMainFrame, CFrameWnd)
	ON_WM_CREATE()
         .
         .
         .
	ON_COMMAND(ID_YOUR_MENU_ITEM, &CYourMainFrame::OnYourMenuItemHandler)
         .
         .
         .
END_MESSAGE_MAP()

And Declare and implement your handler
afx_msg void CYourMainFrame::OnYourMenuItemHandler();

Best Regards
Raj

Conventionally, Only Leaf node of menu handles the event.
It is not a good practice to add event handler for those menu which has child node.
That's why wizards don't support it.

CString Limitation

It seems that CString doesn't work beyond 30,000 characters of length. Can anyone please tell me is there any way to edit strings of larger length so flexibly like CString does.

Actually the following code snippet:

CString sTest="";
for (int i=0; i<50000; i++)
{
  sTest+="*";
}
int iLen = sTest.GetLength();

works fine on my system.

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

At those sort of links I'd be tempted to say just use several CStrings Big Grin | :-D

Seriously though CString is going to be horribly inefficient with this amount of data as it's constantly reallocating and moving stuff around. You're either writing some serious text processing here in which case I would do my own text buffer with the required functionality or you're in need of breaking up that CString. Have a look at CStringArray if MFC is your thing.
If things get difficult when they shouldn't be then often you just need to do more of the easy stuff. It's one of the reasons I love programming. Laugh | :laugh:

Nothing is exactly what it seems but everything with seems can be unpicked.

Thanks to both.

The problem was not with CString, it was something else. Well, thanks a lot.

CString has no such limitation.

Re: Huge increase in memory usage with Debug binary

Hi All,

I added virtual copy constructor for quite a few classes. I see a drastic difference in memory usage before and after the change, that too only with debug binary. When I ran release binary the memory usage is almost the same.

Here below are the memory statistics

Before Change
-------------
Peak Mem Usage & VM Size for Debug binary is: 15 MB & 10.5 MB
Peak Mem Usage & VM Size for Release binary is: 11.5 MB & 8 MB

After Change
-------------
Peak Mem Usage & VM Size for Debug binary is: 29 MB & 26 MB
Peak Mem Usage & VM Size for Release binary is: 12 MB & 8.5 MB

Is it the case virtual copy constructor makes debug binary use more space?

Thanks and Regards,
Nani

You mean in what way I added virtual copy constructor?

Here below is the code:

CValueObjectBase* CashflowVO::clone() const
{
return new CashflowVO(*this);
}

Here CValueObjectBase is base class and clone method is pure virtual method. The clone method of derived class copies the object and return base class pointer.

Hope I have provided the right information.

I thought constructors couldn't be virtual, since they require complete information to create the object.

You are correct, hence my question to him as to how he managed to pull this off.

Actually, this is a method which does the job of constructor.

Here below is the code snippet:

class CashflowVO derived from CValueObjectBase
>>>>>>>>>>>>>>>>>>>>
CValueObjectBase* CashflowVO::clone() const
{
return new CashflowVO(*this);
}
>>>>>>>>>>>>>>>>>>>>

Clone methos is pure virtual method in CValueObjectBase. The below code calls the respective clone method of derived object. Here pValueObjectBaseOrg can be any of the derived class, but respective object is getting copied and pointer is returned to pValueObjectBase.

>>>>>>>>>>>>>>>>>>>>
CValueObjectBase * m_pValueObjectBase = m_pValueObjectBaseOrg->clone();
>>>>>>>>>>>>>>>>>>>>

Hope I make sense here.

Besides the question that needs an answer (what the heck is a virtual copy constructor???)
the memory usage increase was hardly "drastic". Is there a reason you're worried about how
much memory (even if you could get an accurate measurement of it) your app is using in a
debug configuration?
