When you click on any Window you will get a notification from the system which includes the location of the mouse when it was clicked. See here[^] for details of each specific message.

You mean you want to get the Image Height and Width. What Co-ordinate you are talking about?
|
|
|
|

yes, i'm talking about the pixel coordinates (i.e pixel height and width).
|

The bitmap file usually have a BITMAP header, color palette and actual pixel information (Bits referring the color palette or raw bits if color palette not used). The bitmap header will have the height and width of the image.
Quote:
typedef struct tagBITMAPINFO {
BITMAPINFOHEADER bmiHeader;
RGBQUAD bmiColors[1];
} BITMAPINFO;
Taken the above one from msdn. The Quote: BITMAPINFOHEADER
structure has the information you need.

I am not sure this is possible, but I would like to create a basic dialog that serves as a template for other dialog boxes. Ideally Ill make the first base dialog with the size and properties I want.
At this point I know I could then go into the resource editor and add a copy of it and work on the copies. However, I would like to have the ability to then go back and make a change to the template and have the other dialog boxes take on the changes from the template dialog. This add copy method will not do that.
|

|
|
My gut reaction with MFC, which is all I know for UI dev, is no. The dialog script file is just plain crude and doesnt have inheritance built in.
|
|

What would you like on your template? ...really will depend on that... but yes, you should be able to do that, only not through the resource editor, you'll have to do it all through code pretty much.
|
|
|
|
|
I figured as much. I was just hoping there was some mechanism I did not know about. I am not sure what all I want, other than for all the dialogs to have the same size and base styles. It may change which will be a PITA if I have to redo a bunch of dialogs because someone decides they want them just a little wider or some new logo graphic of a different size.

If you're good with MFC or the WinAPI, should be easy to do if the constant is the size and logos. That's easy to accomplish, except when you want to use your template, anything that goes on it will have to be defined programatically rather than though the editor. That will probably only be hard the first time. The somewhat annoying issue with that is the variable text sizes on Win Vista/7 can make drawing things a pain because you have to size anything containing text according to the text size.

i have done that, however i store my template in XML files and load them on runtime. Little difficult and also no UI is available for same, so you have depends on your Gut feeling and principle of coordinate geometry!

I have always wanted to design a software with a great and exotic user interface which includes non-standard and uncommon UI components such as tabs, bars, button and so on. Now, I as eager to find a professional toolkit or suite which helps me to quickly design and use marvelous and inventive user interface in another project like VC++ or Qt.
Does anybody know a product like that?
The examples for the software interfaces I really like are Kaspersky Pure 2012, Folder Lock or even Babylon. All these have a different and pretty UI which is not easy to creat when using tools such as Visual Studio or Eclipse.

You can create anything you like in these development environments; the difficult bit is writing the code.

Remember that C++ (and any other object oriented language) gives you the ability to subclass, so if there's a UI toolkit that gives you something similar to what you want/need, you can always subclass the components to get a personalized or polished look and feel. For example, in MFC, there are a variety of buttons and toolbars already available, but I've derived my own classes from some of these if I didn't like my options already there. It may be a bit difficult the first time you do it, but it's actually relatively simple after that.

Don't. All those "fancy" UI are really hard to use for normal users.
Anyway, all those UI are based on CWnd and are all user drawn and handled.
Good luck.

Rule one. Dont make your UI garish. People dont like it.
Rule two. Make it works like everyone else's. That way its predictable, people like that.
And as for a tool, I always liked MFC and its dialogue wizards.
