Registry Theory Question soup19-Jun-02 12:30 soup 19-Jun-02 12:30  Hi, I have recently been working on my first big C++ application, and it has quite a lot of persistent Registry entries. Anyway, when I want to know an app setting, I am doing AfxGetApp()->GetProfileXXX... to get the setting. My question is this: is it slower to keep calling that function or to hive off the settings and keep updating that hive if the settings are changed? Example #1: A loop 10,000 times with a Registry call each loop is probably slower than reading the value out and then looping 10,000 times. Example #2: An event fires (such as WM_CHAR) that reads a setting and uses it once before the end of the handler. Is this slower than having the external hive? Input, ideas and peep's programming practices in this field greatly appreciated. Thanks in advance, Si Re: Registry Theory Question Nish Nishant19-Jun-02 13:01 Nish Nishant 19-Jun-02 13:01  I recommend that you read the config settings at program startup and store them somewhere instead of re-querying the registry every time you need a value.

I was just wondering whether AfxGetApp() within MFC did some smart cacheing of values. I would have thought not, but here's hoping. Re: Registry Theory Question Michael Dunn19-Jun-02 19:09 Michael Dunn 19-Jun-02 19:09  It's not AfxGetApp() that's slow (trace into it and see), but doing thousands of registry calls is. The registry is a database, and access won't be lightning-quick. As Nish said, read your config into variables at startup, then save it on exit. --Mike-- Just released - RightClick-Encrypt - Adds fast & easy file encryption to Explorer My really out-of-date homepage Sonork-100.19012 Acid_Helm Multiply Copies of same image 19-Jun-02 12:23 19-Jun-02 12:23  Is it possible to copy a parent image and have its children appear in different locations to the parent? I'm trying to create a side on scrolling shoot-em up and I want to be able to fire five (5) bullets at one time but I don't want to have to write the code 5 times... GetBulletStartPoint[1]; SetBulletVisible[1]; If(Bullet = OffScreen) AllowNewBullet[1]; etc etc... Hope this makes sense I can compile what I'e made so far and post on my site if that will help... Re: Multiply Copies of same image Christian Graus19-Jun-02 14:00 Christian Graus 19-Jun-02 14:00  No - you will need to draw them all yourself, you can't make a single image redraw itself automagically. You should be writing it five times though, you should use an array ( maybe as a list ) of Bullet objects and a loop. Christian I am completely intolerant of stupidity. Stupidity is, of course, anything that doesn't conform to my way of thinking. - Jamie Hale - 29/05/2002 Half the reason people switch away from VB is to find out what actually goes on.. and then like me they find out that they weren't quite as good as they thought - they've been nannied. - Alex, 13 June 2002 Tooltips + Codepage / Owner-drawn Oz Ben Eliezer19-Jun-02 12:09 Oz Ben Eliezer 19-Jun-02 12:09  Hey all. I want to be able to display tooltips text in a different codepage from the system's current default codepage (in a non-Unicode OS, such as Windows 98, Windows ME, etc.) Any ideas? Thanks! Outlook Event Sinks 19-Jun-02 11:18 19-Jun-02 11:18  Hey, Im having some trouble with capturing some events in Outlook. I was wondering if anyone had, or could give me an example of how to overide an event such as the "open" event. Right now I have this... I derive my class from IDispSimpleEventImpl... class ATL_NO_VTABLE CDaFun : public IDispEventSimpleImpl<1,CDaFun,&__uuidof(Outlook::ItemEvents)> typedef IDispEventSimpleImpl<1, CDaFun, &__uuidof(Outlook::ItemEvents)> ItmEvents; Then setup a callback... void __stdcall OnOpenItem(IDispatch* Ctrl, VARIANT_BOOL * CancelDefault); and then the sinkmap... SINK_ENTRY_EX(1,__uuidof(Outlook::ItemEvents),0xf003,OnOpenItem) Now Advising im not sure about. Try to get a pointer to the interface i need. Im not sure if Inspectors is right... CComQIPtr <outlook::_application> spApp(Application); CComQIPtr <outlook::_inspectors> spInsp; spInsp = spApp->Inspectors; ItmEvents::DispEventAdvise((IDispatch*)spInsp,&__uuido(Outlook::ItemEvents)); The advise fails, so im not how to set that up right. Please help THanks TENK run a process as a different user Jason Henderson19-Jun-02 11:16 Jason Henderson 19-Jun-02 11:16  I have an ISAPI extension that runs another app when it is finished. This other app needs to have write access to a directory. How can I run this process as another user? I have tried CreateProcessWithLogonW but got a link error. I assumed it was because I was not building in unicode. Unfortunately, I don't have a unicode build configuration so forget that. Is there a way to tell IIS to run a dll as a certain user? Jason Henderson quasi-homepage articles "Like it or not, I'm right!" Re: run a process as a different user Navin19-Jun-02 11:48 Navin 19-Jun-02 11:48  There is the CreateProcessAsUser() API. I haven't used it a lot though - you need to get a security token for the user and pass it in. Although I might soon try to do just this - have an EXE or a DLL that launches another EXE as a different user. I suppose if you could get that to work directly, you could always have IIS launch a DLL which launches an EXE to run as a different user. As for launching a DLL as another user - is that possible? Since a DLL will technically run in the memory space of the executable that calls it, so they are essentially one program - but I'm somewhat ignorant in this regard. Even if you win the rat race, you're still a rat. Re: run a process as a different user Jason Henderson20-Jun-02 3:36 Jason Henderson 20-Jun-02 3:36  You have to call LogonUser before calling CreateProcAsUser. Not sure I want it to load the profile etc. Thanks for the reply. Jason Henderson quasi-homepage articles "Like it or not, I'm right!"

RuiSantiago19-Jun-02 9:13 RuiSantiago 19-Jun-02 9:13  Hello! I'm trying, by code, to insert the '\n' or 0x0D or chr(13) into a EditBox to format the data comingo from a Database. Anyone have a clue on how to do this? Thank you for your time! Re: Character insertion into a Editbox! 19-Jun-02 9:20 19-Jun-02 9:20  Try \n\r that should do it! Papa Murex Co. Re: Character insertion into a Editbox! Chris Losinger19-Jun-02 9:21 Chris Losinger 19-Jun-02 9:21  there are a few ways. the easiest is to add the "\r\n" to the data then do a SetWindowText to add all the data at once. (you need the '\r', or the edit box will draw a little square for the '\n'). CString inData; inData = from database inData+="\r\n"; myEdit.SetWindowText(inData); -c Cheap oil. It's worth it! Image Processing - just like mom used to make. Re: Character insertion into a Editbox! 19-Jun-02 9:22 19-Jun-02 9:22  sData = ... sData += "\n"; m_cEdit.SetWindowText(sData); Re: Character insertion into a Editbox!

Closing window from the far 19-Jun-02 9:12 19-Jun-02 9:12  Hi, I have window A (which might be a dialog or a SDI) and window B which is a dialog. Window A creates window B modally. I wanna have a button on window B which closes both window B and window A regardless of whether it is dialog or SDI but I dunno how. Thanks for your help. R. Re: Closing window from the far 19-Jun-02 9:25 19-Jun-02 9:25  U can do it several ways, but guess the simplest object oriented way would be to pass a pointer of the dialog A to the dialog B, and all the button would have to do is to call: OnOK(); m_pointerToDialogA->OnOK(); Papa Murex Co. 10x Papa 19-Jun-02 9:29 19-Jun-02 9:29  see above
