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~!

Simple is that i want to call a function which is in source file "call_Main.cc" not in class. from the clicked event of a button. 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] Re: keyword 'static' namaskaaram11-Jun-06 22:33 namaskaaram 11-Jun-06 22:33  I think i havent asked the question clearly what i actually ment to ask is : if a member is declared private then it implies, it cannot be accessed by any objects directly. But in the case of static member varaibles, they can be accessed by using 'class name' followed by '::' operator. So wouldnt a private menber varaible declared static loose its significance as private if it can be accessed by by the :: operator???? Re: keyword 'static' Eytukan11-Jun-06 22:38 Eytukan 11-Jun-06 22:38  If it is private , it means it. No matter it is static or not. You cannot access even with a :: operator. <marquee scrollamount="1" scrolldelay="1" direction="up" height="10" step="1">--[V]-- [My Current Status] Re: keyword 'static' namaskaaram11-Jun-06 22:51 namaskaaram 11-Jun-06 22:51  thank u!
