what DefWindowProc does to WM_PAINT message? - C / C++ / MFC Discussion Boards

For my job I have designed a particular scripting language, that's ok, and it works fine.
But now I want to make a program to help write these scripts, so I thought in a SDI application with a RichEditView, and I want to add some intellisense features, like any program enviroment you can find these days, so my question is simple.
Could you someone point me, maybe, an article or something like that that talk about this kind of feature?.
I don't know if I have explained well, I would like my program be able to show ie a list with the script keywords while someone is writing. How could I do that?.

Thank you.

Demian.

what DefWindowProc does to WM_PAINT message?

Hi all:

Yesterday I asked about dialog UI paint problem in which when the dialog overlapped with another window the dialog's UI got different kinds of trailing white strips. Today the problem solved accidentally in which DefWindowProc didn't get called once I finishing paint the dialog customarily, the modification was just a simple substitution from "break" to "return 1". For a hindsight, I know the rough idea behind this, I should have handled the painting by myself solely instead of let system handle it again, but I don't know what DefWindowProc done when I've painted the dialog made the dialog graffitified.

Newbie: how to make PrintPreview the initial view

Hi all, I'm learning how to print in MFC and I know MFC will generate a 'printpreview' view for you once you've got all the printing settings right. I'm trying to find out how to make this 'PrintPreview' the initial view of an application so that when you enter the program with some initial parameters you get a 'PrintPreview' window directly before any operations. Has anyone got any ideas on this? Thanks in advance.

Go to Resource view. Right Click, Add Resource, Then Add Menu.
Customize the menu and call it whereever you want to use.
Programming in Dll is almost same as that of other application.

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.

How to add soap header information in a proxy class

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.
