This might be really basic question but nevertheless I need some help My problem is that I want a button to send two separate messages depending on if it is being clicked or released (Button down and button up) with the mouse pointer. I am using an Visual C++ dialoge application created using the wizard. I just can't figure out how to do it with the CButton class, or if it is even possible. Does anyone have any input on this? I would really appreciate some kick-start help here! Thanks, Larssen Re: Separate actions on Button click and button release _AnsHUMAN_ 11-Jun-06 22:15 _AnsHUMAN_ 11-Jun-06 22:15  Create a class derived from CButton say CMyButton. Now in that class override the OnLButtonDown and OnLButtonUp events. Include the file MyButton.h in the class where you are using the button. Add a variable to the button.(call it m_btn) Open the header file of the dialog and change CButton to CMyButton You are done with this You can test the code by putting message boxes in the button class you created. To test the LButtonUP functionality click anywhere in the dialog and take the mouse on the button with LButton Pressed. Release the Mouse button on the button on the dialog. Somethings seem HARD to do, until we know how to do them. _AnShUmAn_ Re: Separate actions on Button click and button release Hamid_RT11-Jun-06 22:47 Hamid_RT 11-Jun-06 22:47  See Here[^] maybe it is some helpful to you whitesky add source files to embedded VC 4.0 George_George11-Jun-06 21:36 George_George 11-Jun-06 21:36  Hello everyone, I am going to add some source files (.c, .cpp and .h) to a project in Microsoft embedded VC++ 4.0. There are a lot of source files and they are organized in their source tree file structure. I am wondering what is the most convenient way to add them all to an embedded VC++ project. Currently, I have to add them one by one (by "Add files to project" context menu of a project), which will break original source tree structure (which adds all the source files to "Source Files" folder in FileView). thanks in advance, George minimise and maximize button Manjunath S11-Jun-06 21:13 Manjunath S 11-Jun-06 21:13  Hi, I need to create a modeless dialog with minimise and maximize button in win32 application .( so what have to set in sytle attribute in the dialog template .... Manjunath S Re: minimise and maximize button Sarath C11-Jun-06 22:14 Sarath C 11-Jun-06 22:14  I think it is better to draw your own title bar using system colors to get the actualy window effect. That is the best solution for this. its not that much costly. This is your previous post regarding this right?[^] Modeless an modal dialog is not inter-realated with title bar. SaRath.

Remove the redefinition. --Mike-- Visual C++ MVP LINKS~!

Rahul Kulkarni Re: Function Call toxcct11-Jun-06 21:30 toxcct 11-Jun-06 21:30  i suppose the function definition is in .cc file, but the declaration of the function should be in a header file (.h file). then, include your header everywhere the functions declared inside are needed.

First you need to process the WM_LBUTTONDOWN notification message, sent to your butmap’s window. Within the handler, store a true value in a boolean variable, and save the position of the cursor and the scroll position (GetScrollPos). In addition, take the possession of the mouse using SetCapture function. Then, in WM_MOUSEMOVE handler, if the boolean variable is true, scroll the bitmap window according to the current cursor position and stored values. In WM_LBUTTONUP handler, set the boolean flag to false, and release the mouse possession using ::ReleaseCapture. The same actions must be done in WM_CAPTURECHANGED handler. In addition, you can handle the WM_SETCURSOR message in order to change the mouse cursor shape while the bitmap is scrolled.

Re: keyword 'static' happy_ram11-Jun-06 20:56 happy_ram 11-Jun-06 20:56  verify the question once Re: keyword 'static' Eytukan11-Jun-06 21:30 Eytukan 11-Jun-06 21:30  I could guess your question. Static and private has totally different meanings. when you declare a variable private but not static, it means that it can be used within the same class. It cannot be accessed by other members(may be another class). and more importantly, every time an Object is instantiated, a new instance of the variable is created. But when you declare a varible private and also static. It's all the same but the last point, which when new objects are created, it's not instantiated anew, rather all objects share the variable. and when you want to access it, you cannot use the . or the -> operator, you should use the :: operator with the class name preceeding it. now you get it? note, you cannot put "static" in the private,protected,public list. it can coexist with all the three <marquee scrollamount="1" scrolldelay="1" direction="up" height="10" step="1">--[V]-- [My Current Status]
