toolBar-> function --> create my own message send to all dialog boxes ? BrutalDeath021-Feb-04 1:24 BrutalDeath0 21-Feb-04 1:24  Hi, the problem is : I click on a ToolBar button, it sends the ON_COMMAND message --> I treate it in MainFrm.cpp , then, I want to send a "personal message" to all my dialog boxes to adapt their fields. (The MainFrame know nothing about the dialog boxes) so, how can I create my own messages and how can my dialog boxes intercept it ? Have you got an idea ?

BrutalDeath024-Feb-04 0:40 BrutalDeath0 24-Feb-04 0:40  thanks but, I surely not explain well, so : I have an MFC App, with : - a CMyToolBar derived from CToolBar which contain a Button (PastDate) - the View contain a Property Sheet with 3 Property Pages (CHoraire,...) which contains 3 Grids (CGridCtrl from C. Maunder) - the ON_COMMAND of the PastDate button is done in CMainFrame. What I want is : when I click on the PastDate button , it has to change the data shown in the grids. But how ??? I tried the ::PostMessage(HWND_BROADCAST, MY_MESSAGE,...) but I have a link Error. Thanks a loooooooooooooooot BrutalDeath0 Re: toolBar-> function --> create my own message send to all dialog boxes ? Prakash Nadar24-Feb-04 5:06 Prakash Nadar 24-Feb-04 5:06  Since you have handled the message from the toolbar in the main frame, try using SendMessageToDescendants to send it to all the descedants. Or get the handle of the view and send the message to it. Still Alive!!! Thank you God. Do I have to open Add variable wizard at each variable adding in VS2003 ? Gem21-Feb-04 1:04 Gem 21-Feb-04 1:04  In VS 2003, As far as understood I have to open add variable wizard for each new member variable adding and press finish button to add the varible. In VS6 I can add variables without calling wizard at each member variable adding. Is this also possible in VS2003 ? Netmeeting API Shah Shehpori20-Feb-04 23:21 Shah Shehpori 20-Feb-04 23:21  Friends, I am developing front end application using Netmeeting API in the back. I don't want to let user know that i am using netmeeting. But i am unable to get rid of small dialog box that appears while i ask API to dial a number. The dialog box shows the IP address or number i am dialing to. It gives clue that i am using NetMeeting. Can anyone tell me how to get rid of this dialog. Thanks. memcpy hourglass shinay20-Feb-04 23:02 shinay 20-Feb-04 23:02  Is there any way not to show the busy mouse pointer when memcpy is called? I am calling this function in the loop. Seemingly every time i call this function mouse pointer becomes busy and go back to original status. it is kinda bothering that is what my customer said! Is there any way to avoid this? I am using Vs6 on Windows2000 Thanks in advance Shin Re: memcpy hourglass Balkrishna Talele20-Feb-04 23:25 Balkrishna Talele 20-Feb-04 23:25  This is good joke!!! well what you do is before you spend HUGE time in MEMCPY , use API SetCursor(IDI_YOUR_CURSOR) or use thread so that it wont get jammed in your function..I havent seen your code, so this might be the solution regards Balkrishna talele Re: memcpy hourglass Tim Smith21-Feb-04 5:58 Tim Smith 21-Feb-04 5:58  Um, memcpy doesn't show the busy mouse pointer. It is a simple routine that just moves bytes. There is another problem with your application. Tim Smith I'm going to patent thought. I have yet to see any prior art.

Sundaram.R Focus problem Wizard_0120-Feb-04 21:08 Wizard_01 20-Feb-04 21:08  Hi, I work on my control. I have to use WinAPI (not MFC). I have problem that the control doesnt recieve focus input when I click on it. I checked with Spy++ and I saw that focus recieved the parent dialog and the mouse input my control. Do you know why the control doesnt recieve focus ??? Wizard_01 Re: Focus problem Balkrishna Talele20-Feb-04 22:31 Balkrishna Talele 20-Feb-04 22:31  HEllo, Step 1) BEGIN_MESSAGE_MAP(CMYCLASS) MESSAGE_HANDLER(OnFocus,WM_SETFOCUS) . . END_MESSAGE_MAP LRESULT OnFocus(int idCtrl, LPNMHDR pnmh, BOOL& bHandled); or Step *) Just use SetFocus() or If you are not getting mosuse events and other focus, then you will have to use message map of NCHITTEST BEGIN_MESSAGE_MAP(CMYCLASS) MESSAGE_HANDLER(OnNChitTest,WM_NCHITTEST) . . END_MESSAGE_MAP LRESULT OnNChitTest(int idCtrl, LPNMHDR pnmh, BOOL& bHandled); LRESULT CMYCLASS::OnNChitTest(int idCtrl, LPNMHDR pnmh, BOOL& bHandled { return HTCLIENT; } thats all, if you didnt solve the problem, send you code to me, I shall try to solve it, cheers Balkrishna Talele Re: Focus problem Wizard_0120-Feb-04 22:49 Wizard_01 20-Feb-04 22:49  Oh I must use only WinAPI(not MFC). Why WindowProc doesnt revieve WM_SETFOCUS(and key input) when I click in client area and revieve only mouse input ?? Wizard_01 Re: Focus problem Balkrishna Talele20-Feb-04 22:53 Balkrishna Talele 20-Feb-04 22:53  See if you are Creating some static stuff or Something on Parebt window in SDK or ATL, WinProc will give you only parent focus and mouse event, so you need to explicitly tell him that i want child foucus, so you have to add NCHITTEST which is indeed not MFC stuff.... regards Balkrishna Talele "Ask until you dont get satisfaction!!!" Re: Focus problem Wizard_0120-Feb-04 23:13 Wizard_01 20-Feb-04 23:13  ok, control return HTCLIENT, but it still doesnt work :/ Wizard_01 Re: Focus problem Balkrishna Talele20-Feb-04 23:21 Balkrishna Talele 20-Feb-04 23:21  Hello, Simple and best, if your project is hobby project and not important for your company, just zip the code and send it to me....I shall try to find it out!!! with the proper commented question WHAT n WHERE regards Balkrishna Talele Re: Focus problem Wizard_0120-Feb-04 23:57 Wizard_01 20-Feb-04 23:57  I thing that is not good idea It is in pascal. Do not ask why I use that when I have powerful and wonderful language as is C++ . But my teacher on high school dont think so! ((( Wizard_01 Re: Focus problem Chris Richardson21-Feb-04 13:13 Chris Richardson 21-Feb-04 13:13  In your WindowProc for your control, handle the WM_LBUTTONDOWN (and/or WM_RBUTTONDOWN) message. Inside that message handler, call SetFocus, passing in the HWND of your control. There may be another way, but I'm not sure of it. Chris Richardson Problem using Crystal Report 6 DjChris1420-Feb-04 19:24 DjChris14 20-Feb-04 19:24  im having problem in crystal report 6 (using DB2 database). the database was created by our DBA which makes him the owner of the database and tables as well (sample table: DBA.owners_name). i was given an account, PROG_I which gives me minimal authorization to the database (i have to run "set schema DBA" in VC to access/operation with the database). when im trying to print a report file in Crystal report, a message pop-up saying "PROG_I.owners_name" is undefined reference. does anyone give me an approach or technique?... thanks Re: Problem using Crystal Report 6 Steve S22-Feb-04 22:32 Steve S 22-Feb-04 22:32  Sounds like you will need to edit the report changing the PROG_I.column references to DBA.column references. As far as I know, there isn't a simple way to do this, although in CR7 and later I know you can modify these things at runtime from automation code. Be much cleaner to edit the reports though. Steve S Class Design Question Nick Parker20-Feb-04 16:33 Nick Parker 20-Feb-04 16:33  I am currently working on wrapping a third-party control into a MFC-based .dll. I have gotten used to properties in C# and was wondering if there were any design or implementation issues related to the use of the following within my class to mimic properties in C++. private int m_Count; int getCount() { return m_Count; } void setCount(int i) { m_Count = i; } __declspec( property( get=getCount, put=setCount ) ) int Count; - Nick Parker   My Blog Re: Class Design Question Michael Dunn20-Feb-04 17:04 Michael Dunn 20-Feb-04 17:04  I've only used __declspec(property) once (for a parser), but it worked like a charm for me. --Mike-- Personal stuff:: Ericahist | Homepage Shareware stuff:: 1ClickPicGrabber | RightClick-Encrypt CP stuff:: CP SearchBar v2.0.2 | C++ Forum FAQ #include "witty-quote.h" Re: Class Design Question Prakash Nadar20-Feb-04 17:13 Prakash Nadar 20-Feb-04 17:13  Cool, Something new i learned today "When death smiles at you, only thing you can do is smile back at it" - Russel Crowe (Gladiator) Regex Parser monrobot1320-Feb-04 14:33 monrobot13 20-Feb-04 14:33  Hi All, I'm looking for a regular expression parser that is fairly easy to use/implement in an MFC program.
