Object Group Selection Stew28-Jul-02 6:04 Stew 28-Jul-02 6:04  I'm implementing a group object selection tool much like the Power Point and Word's drawing tools where you can draw a box around items you want to select and it will select them all. Anyway, I'm using the DrawDragRect function and when I draw a selection box that I drag towards the bottom right of the screen from my starting point, it works fine. When I drag towards the top left of the screen from my start point though, the inside of the rectangle is drawn in a grey kind of shadowy color. I want it to be transparent like when drawing from top-left to bottom-right. Anybody have any experience with this? sample code needed - CRichEdit nss28-Jul-02 5:06 nss 28-Jul-02 5:06  help! I have been trying to populate a cRIchEdit control with a smal paragraph in vain for the last two days. I used an article from CP. http://www.codeproject.com/richedit/richeg.asp but have had no luck! Any input would be greatly appreciated> I've already wasted a day and a half on this....and am no nearer to seeing my editbox being filled.... thanks, ns Re: sample code needed - CRichEdit Ravi Bhavnani28-Jul-02 6:18 Ravi Bhavnani 28-Jul-02 6:18  Would a simple static text control work for you? That's the easiest way to just display a bunch of text. You can select the "Sunken" look if you want the text to appear as if it's in an edit control. And you can just use "\n" to delimit paragraphs. If you want the user to be able to channge the text, you'd of course need to use an edit control. A straight CEdit should do the job. It seems you're having problems - post the offending code snippet (not an entire method, please) and we'll see what's wrong with it. Remember to surround your code with <pre> and </pre>. /ravi Let's put "civil" back into "civilization" http://www.ravib.com ravib@ravib.com Re: sample code needed - CRichEdit nss28-Jul-02 7:36 nss 28-Jul-02 7:36  DArn! The label idea wont work. Too bad. The code I used for the richedit doesnt crash but doesnt populate the box and I dont know why. Its got callbacks and stuff. I'll post it if you'd like to take a look at it. Re: sample code needed - CRichEdit Ravi Bhavnani28-Jul-02 8:07 Ravi Bhavnani 28-Jul-02 8:07  A static text control works fine for me.

Re: Help with device context please => Jay Beckert28-Jul-02 4:33 Jay Beckert 28-Jul-02 4:33  I don't think there is an actually a way to do that. Once your app is drawn to the screen your app will be in that DC. Other than what Lauren suggested is what I would of done but I don't know exactly what you want. If you find a way I like to know how you did it.

"Human imagination has been sculpted by the universe within which it was born" Hmmmm... comctl32.dll crashes Rakushkin27-Jul-02 22:22 Rakushkin 27-Jul-02 22:22  Hi All ! One problem pursues me for a few years already: all my Win32 apps, written in VC++ (5.0-6.0), crash on the second run under debugger. Toolbar code in comctl32.dll causes access violation. In more details: 1)The crap arises only when the app is run 2 times successively from the VC++ IDE. When running my app standalone, all's ok. 2)The program crashes when a mouse is moved over the toolbar. WM_MOUSEMOVE is finally dispatched to DefWindowProc() in comctl32.dll, and there fails. The mouse coordinates seem to be correct. 3)If toolbar is hidden, it's allright. 4)This bug seems to be not accidental concatenation of circumstances: this happened on different Windows versions, under both VC5 and VC6, after many reinstallations of the VC++ and OS etc, and, finally, with all my Win32 GUI apps - independently of tyhe architecture of the app, and of the way I use tollbars (containing ReBar, different styles, etc.) 5) The bug arises and disappears from time to time, during the course of program development. It seems that it depends somehow on the size of the .exe or something like that. Anyone ever faced this problem ? Any help or hint would be appreciated ! Thanks in advance ! Re: comctl32.dll crashes Anonymous28-Jul-02 5:48 Anonymous 28-Jul-02 5:48  Solution is not into diferent systems or VC++. Try to find bug into your project. I had never this or similar problem and it is imposible to tell you something else. A stupid Win32 UI question - mouse tracking Anonymous27-Jul-02 21:44 Anonymous 27-Jul-02 21:44  I'm trying to create a dialog window, that becomes opaque when a mouse hovers over it and when the mouse leaves the window, it should become transparent again. My problem here is that when a mouse is over a control in the dialog window, it doesn't work the way I want - the dialog does not recognize that the mouse is hovering over it. What should I do? And my second question is: Do you have any how to do the same UI as in Real Player One. I mean: when a mouse is moved over the display window three zoom buttons appear. I actually would like to do it a little bit more different: when I move the mouse over the upper-left corner of the client area of a window the buttons should appear. I'm doing Win32 programming in my spare time for a few months now and I'm nothing but a beginner yet. Sorry if my questions are too stupid. Regards, Z. Re: A stupid Win32 UI question - mouse tracking l a u r e n28-Jul-02 0:31 l a u r e n 28-Jul-02 0:31  check out the SetCapture() and ReleaseCapture() stuff the second point i would solve by putting a static control on the dialog box and make it invisible but use it to capture the mouse and do your button / control thing there "... and so i said to him ... if it don't dance (or code) and you can't eat it either f**k it or throw it away" sonork: 100.18128   8028finder.com Re: A stupid Win32 UI question - mouse tracking Jay Beckert28-Jul-02 4:08 Jay Beckert 28-Jul-02 4:08  Anonymous wrote: I'm trying to create a dialog window, that becomes opaque when a mouse hovers over it and when the mouse leaves the window, it should become transparent again.

You should check for the mouse hover in the controls also. Derive a class fromm your controls and override the mouse events you need to. Anonymous wrote: I actually would like to do it a little bit more different: when I move the mouse over the upper-left corner of the client area of a window the buttons should appear. Define a rectangle with in your view in the upper-left corner of the client area and use that rectangle to test if the mouse is over it and act accordingly. Off the top of my head I can't remember the mouse event, on mouse move? Use the point you get to see if that point is in your rectangle and if so, draw your controls.

Specifing color would also be nice Thanks, ~ Selevercin If you have a problem with my spelling, just remember that's not my fault.
