Re: More CListCtrl woes Navin28-Jul-02 9:29 Navin 28-Jul-02 9:29  Hey, why don't you write your own list control and post it here? While you're at it, write a list box too, as that is pretty annoying (no clean way to change between single select and multiple select at run-time.) Even if you win the rat race, you're still a rat.

Marc Clifton28-Jul-02 8:25 Marc Clifton 28-Jul-02 8:25  So what is it with XP and Microsoft??? All my programs have this stupid white background for the text of the menu bar, while most of Microsoft's apps don't (but a few do). How do I get the background to be transparent? I'm not doing anything wierd other than dynamically creating the menu bar with CMenu. Thanks, Marc can NetRemoteTOD(..) work well in VC++ 6.0?

So I iterate through the map, starting with KeyOptMap::iterator keyIt0 = keyOptMap.begin(); If the maps value satisfies a certain criterion, I want to erase that element from the map for which I'm using for (; keyIt0 != keyOptMap.end() ; ++keyIt0) { if (nPopOffKeyFlag) keyOptMap.erase((*keyIt0).first); } Getting a crash. is it legal to erase like this? I might be erasing the very first key where the iterator started..... Any sugggestions? Thanks, ns Re: A little STL question Joaquín M López Muñoz28-Jul-02 10:03 Joaquín M López Muñoz 28-Jul-02 10:03  You're invalidating the iterator when erasing the element it points to. This can be worked around like this: for (;keyIt0 != keyOptMap.end();) { if (nPopOffKeyFlag) keyIt0=keyOptMap.erase(keyIt0); else ++keyIt0; } Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: A little STL question nss28-Jul-02 10:55 nss 28-Jul-02 10:55  Precisely what I realised when I stepped along! Thanks so much for pointing it out too. I feel pretty goofy for that slipup!!! ns 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.

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.
