Christian Graus15-Dec-02 23:03 Christian Graus 15-Dec-02 23:03  I'm sorry, but I think you probably need to go back to C++ without MFC, or Windows of any kind, if you do not understand this. That is a friendly suggestion, not an insult. To put text into the edit area of a combobox, you call it's SetWindowText method. That is an MFC method, and it requires that you've created a variable of type CComboBox in your modeless dialog box. The rest of the function is basic C++, I showed the declaration ( the bit in the .h file ) to show it needs to not be private ( that is not actually true, but it's the simplest way ), and the definition, where all we do is take the string and shove it into the combo box. You then call that method on the combo box in the method the class wizard defines for you for when you push button 2.

Does anyone have a simple example at their fingertips? Thanks in advance. Happy programming!! Re: Enumeration of Com Ports Olli15-Dec-02 21:02 Olli 15-Dec-02 21:02  Hi Wolfram, there are a couple of hints in the Windows DDK documentation.. Try to search MSDN for 'Serenum', maybe this could help you. Another aproach is try to open all known ports, in most cases it's enough to do this with at least 9 ports (COM1- COM9). If open returns OK, you can use this port, if not, it's already in use or not there... That's the way I do it in my apps... Greetings! Olli! Olli Make it idiot proof and someone will make a better idiot...... Re: Enumeration of Com Ports Wolfram Steinke15-Dec-02 21:34 Wolfram Steinke 15-Dec-02 21:34  The COM1-COM9 is what we did and thought is was a big enough choice to connect a single device up, but we had a bug report that COM10 was missing. Hence I thought if I enumerate what is actually installed there should be no further debate. Happy programming!!

Well I have it now Happy programming!! what does this menu command error warning message mean? trustno115-Dec-02 15:39 trustno1 15-Dec-02 15:39  hi everybody, i made a couple customized commands on my menu. i bind all the event handlers to the commands and they work correctly.. when i was running/testing my program, i check out the debug/output windows and i noticed i keep on getting error warning messages on the commands that i defined.. can someone please tell me what does this message mean? altho it doesn't affect the functionality of the program, i want to know what does it mean exactly.. thx in advance.. the error message: Warning: no message line prompt for ID 0x0098. Re: what does this menu command error warning message mean? Michael Dunn15-Dec-02 16:06 Michael Dunn 15-Dec-02 16:06  When your main frame has a status bar, MFC shows flyby help in the status bar for the selected menu item. The debug msg is saying that you don't have a flyby help string for the menu item with ID 0x98. You can set a help string by double-clicking the menu item in the menu editor, then filling in the "Prompt" field in the property sheet. --Mike-- If it doesn't move and it should: WD-40. If it moves and it shouldn't: duct tape. 1ClickPicGrabber - Grab & organize pictures from your favorite web pages, with 1 click!

Mr.Freeze15-Dec-02 14:45 Mr.Freeze 15-Dec-02 14:45  Hi, I have an application with many tab controls (and in many of them I have other sub-tab controls) and I feel that it is heavy/troublesome to create new tabs or to maintain the existing ones. Is there a way where I could just edit new tab controls visualy without having to create a new dialog for its content everytime? I imaging being able to add a tab control to my dialog. Then I would simply specify the labels for my different sheets and by clicking a specific label, its content would be displayed and editable. Now I always have to create a new dialog for every tiny sheet, then programatically set up everything and see the result only when running the application. Thanks for your help interesting problem Sunnygirl15-Dec-02 14:04 Sunnygirl 15-Dec-02 14:04  hello @all, i have a dialogbased program. there a two buttons (eg. button1 and button2). if i press button1 first i get a new dialog (ID_DIALOG_COMBO) with a combobox (m_ctrlComboBox). if i press the button2 a CString (CString mystring) should be enterd into the combobox from the ID_DIALOG_COMBO. how can i do this???? thank you very much this is only an example, to explain the real background would be take to much time sunny Re: interesting problem Colin Urquhart15-Dec-02 14:48 Colin Urquhart 15-Dec-02 14:48  Looks like you need a modeless dialog.

Make a function to refresh your combo and call it through any initialized pointers. Maybe use a CPtrArray. 'sqrt' : undeclared identifier rbc15-Dec-02 13:03 rbc 15-Dec-02 13:03  Why is that Visual C++'s GUI knows about sqrt yet the compiler doesn't? As I edit my source I typed in sqrt and as I start to type in the paramters the GUI presents me with 3 different prototypes of sqrt ... I think cool Visual C++ knows about sqrt ... so I typed sqrt( myDouble ); as per the GUI. Yet I get a compiler error?
