ActiveX events from automation server (.EXE) ? 4-Jul-02 1:36 4-Jul-02 1:36  I'm writing a automation EXE server in VC++ 6.0 and I want to send COM/ActiveX events to the calling program... is it possible and how ? The project was created as a MFC application with Automation support and works fine as a Automation server for my client application. Now I just need to notify the client of events in my automation EXE application. Please help.... thanks Re: ActiveX events from automation server (.EXE) ?

For example if the user clicks on a menu item Spy++ loggs the following messages: WM_MENUSELECT WM_COMMAND wNotifyCode: 0 (sent from a menu) wID:7224 If I doubleclick on the WM_COMMAND log a new windows opens show the parameters (wParam and lParams) sent by WM_COMMAND. Often these values have a wParam like 00001C38. Now I want to emulate this message. I tried: SendMessage(wnd,WM_COMMAND,00001C38,0); But this doesn't compile. So how do I need to write the wParam/lParam parameter shown in Spy++ in order to use it in my own SendMessage function? thanks in advance modified 12-Sep-18 21:01pm.

I've always defaulted to using the #pragma once but have noticed that others tend not to use it and favour the #ifndef instead, why is this? Am I missing something very simple? Dylan Kenneally London, UK Re: #pragma once and #ifndef Alan Chambers4-Jul-02 1:16 Alan Chambers 4-Jul-02 1:16  Good point. The #ifndef statement is only included in VC++ for backwards compatibility on older compilers and (according to MSDN) the #if !defined statement is supposed to be used instead (though it gives no reason as to why? surely the #ifndef code would be more portable because of this?). The #pragma statments are platform independent compiler directives, but I'm not sure of the difference between that and #ifndef or #if !defined, if there is any at all. I would like to know for sure though . Alan.

You can have some operations in the latter case. For instance: // in header.h #define A #define B // in anotherheader.h // you can use #if !defined A AND !defined B #include "header.h" #else #include "secondheader.h" #endif Best regards, Alexandru Savescu Re: #pragma once and #ifndef markkuk4-Jul-02 1:21 markkuk 4-Jul-02 1:21  The #ifndef block is portable, #pragma is non-portable by definition. Re: #pragma once and #ifndef Michael Dunn4-Jul-02 7:32 Michael Dunn 4-Jul-02 7:32  The #ifndef version has a nice advantage in that you can test whether a header has been included by checking #ifdef _THISDEF_. You can't do that with the #pragma version. And, as has been mentioned, the #ifndef way works on every compiler (for those who have to worry about portability). --Mike-- Just released - RightClick-Encrypt - Adds fast & easy file encryption to Explorer My really out-of-date homepage Sonork-100.19012 Acid_Helm OnUpdate(CCmdUI* pCmdUI) isnt called John Oliver3-Jul-02 23:47 John Oliver 3-Jul-02 23:47  Hello I have two CDialog based classes, both with toolbars, using the technique used in the MSDN MFC sample dlgcbr32 which describes how to use toolbars and status bars in dialogs by overriding these particular control classes I created the first class a few years ago and it works. I cannot get the toolbar button states to update in the 2nd class which I recently created, although the class is similar to the first. I cannot get OnUpdateButtonX(CCmdUI* pCmdUI) to be called - CDlgToolBar::OnIdleUpdateCmdUI isn't being called. Can anybody tell me what methods or messages need to be present for OnIdleUpdateCmdUI to get called.

The OnKickIdle method isn't called. I'll keep trying but in case anybody has spare time here's a checklist of what's going on: -Toolbar has same resource ID as menu. The buttons have same IDs as menu items. Menu items are updated Okay but toolbar isn't -Class has CDlgTool member, which is derived from CToolbar and has OnIdleUpdateCmdUI method, which isn't called -Dlg shown non-modally m_calcDlg=new CCalcDlg(this); m_calcDlg->Setup(m_report,m_UBuckling); m_calcDlg->Create(); m_calcDlg->ShowWindow(SW_SHOWNORMAL); After this I swear I'll never write a CDialog based app. ever again! bye, John MAKEWPARAM ??? Alek3-Jul-02 23:09 Alek 3-Jul-02 23:09  I need my program to send a message which I define. as below: #define WM_MYMSG WM_USER+100; WPARAM wp; wp = MAKEWPARAM((WORD)0x200, (WORD)0x450); ::PostMessage(NULL, WM_MYMEG, wp, 0); I code a .dll to get this message and then to do something. The problem is, in the program, I get the correct wp value, but when I post the message to the .dll file, it get the wrong value. I use hook function to get this message. It get the message but the WPARAM parameter is wrong. Does anyone could give me some suggestion ? Thanks a lot.

I have read some sample codes and write a simple program. It has a dialog with a button and a groupbox. When the button is pressed, an image is drawn to the groupbox by retrieving its hDC. This works fine but I don't know how to keep the image visible after refresh. How to handle this (like AutoRedraw in VB?) in VC? As a related question, I have tried to modified the program so that the dialog is a pop up window rather than the main window. I want to display the image as soon as the dialog is visible. I have tried to put the drawing code in OnInitDialog() and DoModal(), but got no luck. I guess it is the same refresh problem as above, but I am not sure. Will this problem be solved when the above refresh problem is solved? Or I need some more special handling? Thanks in advance.
