How to get datas from an edit control (in the toolbar) by pressing return (enter) ?

CrocodileBuck

Hi there:-D, i coded a small app. with an editbox in the toolbar. When the user makes an input(some numbers) in this editbox i want to store this number in a variable after the user has pressed return (enter) for further calculations. I'm tried this now for some houres without any success ;( :confused: Idont want to post to much or to small code snippets, so i coded a very small sample program (39 kb) only a toolbar and an editbox in it and the same problem :^) ! You can download it here: http://www.filehosting.at/files/download.php?file=f767c44c627cfdb696cb0cea5e24b8be You have to copy the link in your browser :confused: Only a click on it isn't enough :confused: Pleeese help me, it's really important for me! Thousand Thanx for yor help ! ;) best regards croc

You can subclass the edit control and look for the enter key press. When the enter key is pressed you can post a message to another window to do the processing of the edit control contents. See method II here: How To Use the ENTER Key from Edit Controls in a Dialog Box[^] Also, a Google search on "enter key edit control" yields much info. Mark

Subclassing a control is the same for a window as it is for a dialog. You must have an HWND for the edit control if you put it there :) Subclassing Controls[^] If you're using MFC it's much simpler. Mark

Ok, i'put this code in the newToolBar.cpp: BOOL New_cToolBar::PreTranslateMessage(MSG* pMsg) { if (pMsg->message==WM_KEYDOWN && pMsg->wParam == VK_RETURN ) { if (pMsg->message==WM_KEYDOWN && pMsg->wParam == VK_RETURN ) { if ( ID_nEDIT ) { MessageBox( _T("Got it!") ); } } } return New_cToolBar::PreTranslateMessage( pMsg ); } but int won't work ??? best regards Croc

Hi Mr.Salsbery, >>>If you're using MFC it's much simpler.<<<<br mode="hold" /> ...but i am usin g the glory MFC *heut* i tried it for more than 4 hours and i think i couldn't findd my mistake !!! best regards hopefullx Croc

That won't work because the message goes to the edit control, not to the toolbar :) Mark

In that case... Derive a class from CEdit Create the edit control using your derived class In the derived class, add a handler for WM_CHAR In the WM_CHAR handler, look for the enter key (as shown in the first link I posted) If the enter key was pressed - do whatever you need to do For all other keys, pass the message on to the edit control (call Default();)

Perhaps you could have a look on my Code i posted !? Thx Best regards croc

Many thx Mr. Salsbery, this will work, but only in a seperate project! Now i try to put your code in my code with the edit in the toolbar ! Where and how have i to implement it ???:confused: I never did anything in the MFC that was as complicated like this ! Many Thanx Croc

You can't add another class to your project? :) How did you get the edit control on the toolbar (the code)?

??? Shur i can add classes but i'm ....:confused: ! I don't know where i have to implement your code and i don't know how to do it ! I tried it too long i think ! :( This is the declaration of the membervariable of my edit in NewToolBar.h : public: //************************************************************************************************************ CEdit m_Ctrl_EDIT; //************************************************************************************************************ In NewToolBar.cpp: BOOL NewToolBar::LoadToolBarEx(UINT id) { BOOL bReturn; bReturn = CToolBar::LoadToolBar(id); // Zugriff auf Elemente der Funktion LoadToolbar() int iPosition = CommandToIndex(ID_nEDIT); SetButtonInfo(iPosition,ID_nEDIT,TBBS_SEPARATOR,EDITLEN); CRect rect; GetItemRect(iPosition, rect); rect.bottom = 20; DWORD dwStyle = WS_CHILD|WS_VISIBLE|WS_TABSTOP|ES_AUTOHSCROLL;/*ES_NUMBER|*/ m_Ctrl_EDIT.CreateEx(WS_EX_CLIENTEDGE,_T("EDIT"),NULL, dwStyle, rect, this, ID_nEDIT); return bReturn; } i use the menber !!! i don't know how to implement code into mine, this is the prob ! Could you perhaps show it on my sample i posted, i know it's not the general way, im not to lazy, it simply won'work :( :( :( :sigh: :sigh: :sigh: :(( :(( :(( Thanx a lot Best regards Croc(master of desaster)

CEdit m_Ctrl_EDIT;

Change that line to CMyEdit m_Ctrl_EDIT; I gave you code that can be separated into a .h and a .cpp file. Do that, and add the files to your project. :) Add the following line above the NewToolBar class decalration: #include "MyEdit.h" That's it!

I could, but you wouldn't learn anything. You should (IMO) be able to easily add classes to your projects. You'll be happier in the long run I bet :) Mark

Hi Mr.Salsbery, yap i'm sure you are right, the long way is better, and i'm able to add classes to my project :sigh: I added your code bur it still won't work ! :( http://www.filehosting.at/files/download.php?file=422e731948daac3a203df0de8c83b21b Thax a lot Best regards Croc :sigh:

CrocodileBuck

Hi, i don't get an error message ! It simpy dont work ;) :^) :sigh: Best regards Croc

If you put a breakpoint in OnChar() and run it in the debugger, is it ever hit when you type in the control? If not, put a breakpoint in the CMyEdit constructor. Is that ever hit? If not then you didn't use a CMyEdit instead of a CEdit. I'd look at your code if it was in a ZIP - I have no unrar utility. Mark
