wouldn't be a little more efficient to just send the CB_GETTEXT message, passing the LPSTR to be filled in directly, rather than creating a CString, having the framework do what I just said, and converting it to an LPSTR? Also, I think that the other message would be CB_GETTEXTLEN?
onwards and upwards...

It would be more efficient, but probably not worth the effort, here as it is to be used in a cobol DLL. Since the text is to be retrieved from a combo box, it is unlikely to be very long either, so the little execution time saved is probably not very relevant here.

While using simple MAPI in VC++ , how should I be specifying the Mail server addresses ?
|
|
|
|
|
Either by host name or IP address. If you use host name and it doesn't work, it could indicate a DNS problem.

I have script host embeded inside my MFC & ATL app.
It mostly reads/executes JScript code sending results back to MFC View to be displayed.
Program runs very fast when started from local drive, also I can place all scripts on shared netware volume and it will still take less then 1sec to display interface.
Trouble comes when executable is placed on netware volume. It takes 25sec to display first screen vs << 1sec local. After that everything runs fast again.
Profile lists
CWinThread::PumpMessage 27.9 seconds
AfxWinMain 31.8 seconds
IsLink 4.5 seconds
CMDIFrame::DefWindowProcA 3.5second
Not entirely unexpected as looks like system is waiting....
Numega TrueTime even more dramatic:
Application time: 0.29%
System Time : 99.71%
System Time: WaitForMultipleObjectsEx 99%
This function has been called by LoadRegTypeLib 90%
and GetFileAttribEx - 5%....
Those function called 100% by SetScriptState(SCRIPTSTATE_CONNECTED);
Have anybody seen such behaviour????
Any1 aware of any issues btw Netware and MFC & ATL?
P.S. I tried to SetCurrentDirectory to temp and it had no imact...
Compress executable with UPX... UPX unpacks file inside env "C:\TEMP" still darn 25seconds plus to start....
Any suggestions....
Thanks

I have a Winhelp file that calls a Microsoft DLL named HLP95EN.DLL
RR("HLP95EN.DLL","MsoCF","I=SII")
Here's what I know about this:
1. RR() is used to register a routine, which can then be used as a macro by Winhelp
2. the routine's name is "MsoCF"
3. the "I=SII" lists the routine's parameter types: LPSTR, int, int
Here's what I don't know:
1. what does this routine do?
2. in general, is there a way to get the contents of a Microsoft routine?
3. what does the "I= mean?
4. I understand that LPSTR specifies a pointer to a string, but since a Winhelp file is not a C program, I can't see how to assign a pointer to a string.
Could I send an actual string, eg: MsoCF("banana",1,2)?
I appreciate your help,
Al

I'm developping a Winamp visual plugin. I use MFC.
I have a CWinApp derived class (instance is myApp), that has for members init, config, render and quit that are mapped to exported c functions (that Winamp retrieves).
I create a dialog box, instance of a CDialog derived class. I call Create to launch it modelessly. When I close it by the x close button (IDCANCEL) it closes. I can stop the plugin. When i stop Winamp it crashes. When I call DestroyWindow from myApp it crashes.
I tried several solutions : with or without delete in PostNcDestroy, with or without delete from myApp, in a CWinThread derived class, with DestroyWindow in OnCancel or not, and other parameters. There are always problems, depending of those parameters. Most of the time Winamp crashes when the dialog is closed, sometimes some way of closing it works.
Can someone explain how to implement such a CDialog derived class, and how to use it in a modeless way (with a pointer, new, delete and functions such as CreateMyDialog, ShowMyDialog, HideMyDialog, DestroyMyDialog) ?

Hello people,
I am trying to catch the WM_COMMAND message of a certain button in an external application. Catching works fine with both WH_CALLWNDPROC and WH_CALLWNDPROCRET hooks. But after the catch I want to WM_NULL it, so the app wont actually execute the function that the button calls.
After some browsing through the MSDN, it seems like the WH_GETMESSAGE hook is the only one that can actually modify messages. However, changing my WH_CALLWNDPROC hook to a WH_GETMESSAGE hook resulted in nothing. It seems as if WM_COMMAND never gets processed by WH_GETMESSAGE.
It may be that WH_GETMESSAGE is the wrong hook to catch WM_COMMAND, but then how SHOULD I do it? WH_CALLWNDPROC can't modify the message, only inspect it...
Thanks,
- Fahr

I'm using the CHtmlEditCtrl class which encapsulates HTML editing function. I would like to be notified when the control gains the focus, so that I could enable some commands.
I've created a devired class, but my new class doesn't get the focus notification!
Here is the declaration of my class:
<br />
#pragma once<br />
#include "afxhtml.h"<br />
<br />
<br />
class CMyHtmlEditCtrl : public CHtmlEditCtrl<br />
{<br />
DECLARE_DYNCREATE(CMyHtmlEditCtrl)<br />
DECLARE_MESSAGE_MAP()<br />
public:<br />
CMyHtmlEditCtrl(void);<br />
virtual ~CMyHtmlEditCtrl(void);<br />
afx_msg void OnSetFocus(CWnd* pOldWnd);<br />
};<br />
and the implemantation file (.CPP):
<br />
#include "StdAfx.h"<br />
#include ".\myhtmleditctrl.h"<br />
<br />
IMPLEMENT_DYNCREATE(CMyHtmlEditCtrl, CHtmlEditCtrl)<br />
<br />
CMyHtmlEditCtrl::CMyHtmlEditCtrl(void)<br />
{<br />
}<br />
<br />
CMyHtmlEditCtrl::~CMyHtmlEditCtrl(void)<br />
{<br />
}<br />
BEGIN_MESSAGE_MAP(CMyHtmlEditCtrl, CHtmlEditCtrl)<br />
ON_WM_SETFOCUS()<br />
END_MESSAGE_MAP()<br />
<br />
void CMyHtmlEditCtrl::OnSetFocus(CWnd* pOldWnd)<br />
{<br />
AfxMessageBox ("Got Focus!");<br />
CHtmlEditCtrl::OnSetFocus(pOldWnd);<br />
}<br />
What is going wrong?
Thks in advance!

Have you checked with Spy++ that WM_SETFOCUS is actually being sent to the control?

The MSHTML control may be preventing it from being passed on. You could try putting a PreTranslateMessage() into your derived view and/or MainFrm.

Thks for your answer. Even in the PreTranslateMessage, I can't receive the WM_SETFOCUS message! Where is the pb?
<br />
BOOL CMyHtmlEditCtrl::PreTranslateMessage(MSG* pMsg)<br />
{<br />
if (pMsg->message==WM_SETFOCUS)<br />
AfxMessageBox ("Focus!");<br />
<br />
return CHtmlEditCtrl::PreTranslateMessage(pMsg);<br />
}
Thks in advance!

Thks for your help!
I will explore the web sites you give me.
When the control gets focus, I see that it receives the 0x0118 message, but I don't have further information about this message. I will use it instead of WM_SETFOCUS.

This appears to be undocumented so using it is not wise.

This is for an MDI program (mfc) with visual c++ 6.0
Probably a pretty easy question:
I am using CFileDialog for open/save as file operations. I want to be able to create an instance of the dialog, change the working directory in code at runtime, and then domodal() having the dialog show the directory i specified as the current directory. I'm able to get the directory names i want to use in the format CString (i.e. "c:\project\dbc") and i want to use this path/directory string to change the directory but i can't seem to figure out how to do it.

You need to set the lpstrInitialDir member of the OPENFILENAME member struct (m_ofn) in the CFileDialog class. See the doc for more info.

Thanks, that works great. I must have missed that m_ofn data item.

I am trying to get the text out of an AOL Messenger Chat session. AIM has an Internet Explorer Server, but after I get a handle for it and try to read the text, I come up with an empty string.
Here are the steps that I am doing
I get a reference to a IHTMLDocument2 interface
from that I get a pointer to IHTMLElement interface by calling the get_body function from the IHTMLDocument2 interface.
Then I call the following functions out of desperation on the IHTMLElement Inface
get_innerHTML returns blank
get_innerText return blank
get_outerText return blank
get_outerHTML returns "<BODY><XMP></XMP></BODY>"
I tried the same thing with Yahoo Messenger and it worked perfectly.
Any suggestions
Thanks

Try the GetDocumentHTML method which returns the entire HTML code.

Hi
Thanks for your help
GetWindowText() only works if the window is owned by the process calling this function. So that wont work for me but I tried sending the WM_GETTEXT message and that worked.
Thanks Again.
