Best regards, Eugene Pustovoyt Re: Handle the WM_NCLBUTTONDOWN 3-May-02 10:11 3-May-02 10:11  Hi, I think you're misinterpreting the WN_NCLBUTTONDOWN message. It does not detect clicks outside the client area. It detects clicks on the non-client area. For example, if you add that handler to your main window and you click on an empty space in the menubar, the event will fire. So basically, that event is useless for an edit because an edit does not have a non-client area. If you're trying to detect mouseclicks outside the edit, maybe you should just add a handler for WM_LBUTTONDOWN to the edit's parent window.

Any clue. Sanju The wizard Re: Converting GDI region to GDI++ path Paul M Watt3-May-02 5:15 Paul M Watt 3-May-02 5:15  The only thing that I know of is to decompose a region into all of the separate rectangles it contains, further decompose the rectangle into its points, and find the concave hull that the resulting polygon creates. The only problem with this is you will have to figure out another way to find the holes in the region.

Best regards, Eugene Pustovoyt Toolbar buttons in Dialog Box LittleYellowBird2-May-02 23:33 LittleYellowBird 2-May-02 23:33  I have added a toolbar to a dialog box and I wanted to 'Enable/Disable' and 'push in/pop out' the buttons to show the current status. I have achieved this in the past within the Main Frame toolbar using a user interface (UI) handler function, but although I can add this function it never seems to get called. Is this because the toolbar is attached to the dialog box, or am I doing something stupid? Any help appreciated, thanks ali p Re: Toolbar buttons in Dialog Box Shog93-May-02 5:16 Shog9 3-May-02 5:16  ali p wrote: Is this because the toolbar is attached to the dialog box Yes. OnUpdateCmdUI() will not be called for the toolbar. You can call it yourself if you really want to do it that way, or you can just use GetToolBarCtrl().EnableButton(), GetToolBarCtrl().CheckButton(), etc. -------- When will I realize that this skin I'm in Hey, it isn't mine And when will the kill be too much meat for me to hide on... -- Blind Melon, Skinned Re: Toolbar buttons in Dialog Box LittleYellowBird7-May-02 1:18 LittleYellowBird 7-May-02 1:18  Thanks, I gave this a go and got it working.

I know this is a bit of a beginner question, but I never had to do this task before and am a bit confused as the best way to do it. I have a button on a dialog, which I want to place a bitmap on (specifically, the little printer bitmap under the graphics/bitmaps directory of VC++). I can either make a CButton object, and do it this way, or use CBitmapButton. I want the button to work like a toolbar button (that is, in the way it looks, and the fact only 1 bitmap is used for all button states, not the up to 4 that CBitmapButton uses). I was going to use a CButton and place a bitmap on it, but I couldn't figure out how to get my bitmap (which is in the resource file as IDC_BMP_BITMAP) into an HBITMAP parameter, which CButton requires. I tried using CBitmap to get a HBITMAP handle back, but I couldn't quite figure out how to do this. I am sure this is a simple procedure, but it has me stumped tonight Thanks in advance for any help! Re: Button with Bitmap Image Michael P Butler2-May-02 23:18 Michael P Butler 2-May-02 23:18  Have a look at the fantastic CButtonST http://www.codeproject.com/buttonctrl/cbuttonst.asp Michael Communication is the first step towards enlightenment. Re: Button with Bitmap Image GUEJO4-Jun-02 0:47 GUEJO 4-Jun-02 0:47  I used a class very very useful : CxSkinButton If you want to have button of every shape and bitmap, try this link and I think you'll be surprised...;) http://www.codeproject.com/buttonctrl/CxSkinButton.asp Maybe you could tell me something too ?... Actually I'm trying to display more than one bmp at the same location but it doesn't work properly... I use the SetWindowPos function to place the bitmap and stretch it (or shrink it) to the correct size. It works well for the position and the size but not for the Z-Order (the first is over the second and I want the contrary). Setting the first parameter of the SetWindowPos to '&wndTop' does not change anything. If you could help me... Should computing stay as a source of benefit or become like knowledge : free and opened to every one ?...

Public key should be able to decrypt message and only private key would be able to encrypt it. I could use RSA and distribute private key, but i think that it is possible to generate public key from private key. Am i wrong? Re: I am looking for cryptografic algorythm... markkuk3-May-02 0:06 markkuk 3-May-02 0:06  In RSA, messages encrypted with private key can be decrypted with the public key, that's how RSA is used for digital signatures. Acquire a View HANDLE :: MFC valikac2-May-02 21:09 valikac 2-May-02 21:09  Hi. I often see function parameters requiring a handle to a window. I believe the handle to main fram is m_hWnd. In general, how do you get a handle to a window from main frame to any view including splitters? Thanks, Kuphryn Re: Acquire a View HANDLE :: MFC Nish Nishant2-May-02 21:19 Nish Nishant 2-May-02 21:19  kuphryn wrote: how do you get a handle to a window from main frame to any view including splitters? All CWnd objects will have an m_hWnd which is the underlying window HANDLE. But to be safe call IsWindow on this handle before trying to do stuff with it, unless you are sure it is a handle to a valid window Nish Check out last week's Code Project posting stats presentation from :- http://www.busterboy.org/codeproject/ Feel free to make your comments. Re: Acquire a View HANDLE :: MFC valikac3-May-02 3:52 valikac 3-May-02 3:52  Thanks. You wrote "call IsWindow() on this handle." How do you go about calling IsWindow on a handle?

Re: Acquire a View HANDLE :: MFC valikac3-May-02 8:59 valikac 3-May-02 8:59  Ahh. Thanks. In other words, IsWindow() *internally* check m_hWnd to see if it matches that of the current view/window. Kuphryn Re: Acquire a View HANDLE :: MFC Nish Nishant3-May-02 13:54 Nish Nishant 3-May-02 13:54  Actually what it does is to verify that the window handle we have points to a valid window. There might be a situation that a window has closed but we still have a handle to it. In such situations, we must use this function.
