Re: EN_CHANGE? Rassman19-Nov-01 5:05 Rassman 19-Nov-01 5:05  OnChange for the control allows you to check per key. It means though that you have to grab the text of the box, check it, then indicate the error to the user. For a box that with a maximum of two characters its fast enough, though it can be equally argued that for a box with two characters checking OnExit or when the return key is pressed is just the same. If your text could be long the OnChange check may be most desirable since the user may need to know before going too far ahead. In this case the first possible method is wastefull, that is, collecting all text and checking it all every time H He Hel Hell Hello Hello W etc For a 256 character line, there is a lot of waste. So, it is better to remember where you have already checked and where the cursor currently is. If you look at CEdit you will find possitional data available to you which you can use for this within the ::OnChange() We do it for the joy of seeing the users struggle.

Question about ComboBox Ernest Laurentin16-Nov-01 5:15 Ernest Laurentin 16-Nov-01 5:15  I just heard there's a limitation under Windows 98 about the number of ComboBox that an application can create. I can't believe it! Did anyone of you heard about this. I searched the MS Knowledge Base but I didn't find anything yet. -- God bless the World Re: Question about ComboBox Joaquín M López Muñoz16-Nov-01 7:29 Joaquín M López Muñoz 16-Nov-01 7:29  I don't know of any special limitation about comboxes, but it is a well known fact that Win9x systems can only hold 16,364 windows at a time (this includes not only top-level but child windows as well), which is admittedly a little low. On NT/2000/XP the only limit is system memory, as far as I know. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Question about ComboBox Mike Nordell18-Nov-01 12:28 Mike Nordell 18-Nov-01 12:28  As any listbox it can only hold 32K entries (actually, I believe it's 32767). Try searching MSDN for Virtual Listbox. IIRC Paul wrote a Virtual List Control for Win3.x (or was it Win9x?) "a few years" ago. automate excel Gérald Mercet16-Nov-01 4:25 Gérald Mercet 16-Nov-01 4:25  is anybody could explai me how i could create an automation which could simply open a specific workbook, a specific worksheet, update the data(using shift+F9) and close it. I would like to create this automation so that i could have a button in my dlg box app, when pushed it will update the data i need for my calculations??? thanks in advance gerald Re: automate excel Carlos Antollini16-Nov-01 4:57 Carlos Antollini 16-Nov-01 4:57  Look in the MSDN Article ID Q192348 You can find it all that you need, the explanetion is for Excel 97 but it can help you with other versions..

Derek Price16-Nov-01 4:02 Derek Price 16-Nov-01 4:02  Hello, When an application states it requires 32MB of memory to run, how did the developer determine this? Is there a clear cut way or are they just guessing? Any ideas? Thanks! Derek Re: Determine Memory Requirements? Daniel Turini16-Nov-01 5:07 Daniel Turini 16-Nov-01 5:07  I just guess. The total memory ammount depends on what other software you are running. There are articles on MSDN that will tell you how to do this, but, in a real world, just try your software on different configurations and recommend to your users what they feel comfortable. Furor fit laesa saepius patientia a question about check box Gérald Mercet16-Nov-01 2:02 Gérald Mercet 16-Nov-01 2:02  I have a dlg application in which i would like to put 2 check box. For each check box there is a boolean variable, i would like to use those variables so that my app could call the right function when one of this check box is flagged. But, when i try to compile my code i have this kind of warning message: warning c4800:"int":forcing value to bool "true" or "false"(performance warning) So, i don't know if it's really a big pb. Perhaps i should use another type of button as a radio button, i don't know! Thanks in advance for your help. gerald Re: a question about check box markkuk16-Nov-01 2:26 markkuk 16-Nov-01 2:26  You can safely ignore this warning, or you can get rid of it by changing the type of variables from bool to int. Re: a question about check box Daniel Turini16-Nov-01 2:27 Daniel Turini 16-Nov-01 2:27  Please, post a code excerpt that raises the warning. Probably, you're doing something like this: int b; b = true; and you should be doing this: bool b; b = true; Tip: press now the reset button to test your memory. Re: a question about check box Gérald Mercet16-Nov-01 2:48 Gérald Mercet 16-Nov-01 2:48  first i post the function which use it: double EuropeanSwaption::CallOrPutEuropeanSwaption(COleDateTime StartDate,COleDateTime SwaptionEndDate,COleDateTime SwapEndDate,double Strike,int BaseAnnuelle,double Nominal,int Periodicity,_variant_t RateTable,_variant_t VolatilitySurface,bool CheckPayeuse,bool CheckReceveuse) { double Price; if(CheckPayeuse==TRUE && CheckReceveuse==FALSE) Price=CallEuropeanSwaption( StartDate, SwaptionEndDate,SwapEndDate,Strike,BaseAnnuelle,Nominal,Periodicity,RateTable,VolatilitySurface); if(CheckPayeuse==FALSE && CheckReceveuse==TRUE) Price=PutEuropeanSwaption( StartDate, SwaptionEndDate,SwapEndDate,Strike,BaseAnnuelle,Nominal,Periodicity,RateTable,VolatilitySurface); if(CheckPayeuse==TRUE && CheckReceveuse==TRUE||CheckPayeuse==FALSE && CheckReceveuse==FALSE) AfxMessageBox("Il faudrait peut être faire un choix!!"); return Price; } this first function is used in the calculation part. Now i could show a sample coming from the the dlg code, i just post the line which call the function described above: m_dlgPrice=eur.CallOrPutEuropeanSwaption(m_dlgStartDate,m_dlgSwaptionEndDate,m_dlgSwapEndDate,m_dlgStrike,m_dlgModeDate,m_dlgNominal,Periodicity,"TauxZCEURO","SurfaceVolatilite",m_dlgPayeuse,m_dlgReceveuse); where eur is an EuropeanSwaption object, and m_dlgPayeuse, m_dlgReceveuse are the 2 variables linked to the 2 check box put in the dlgbox. Re: a question about check box Daniel Turini16-Nov-01 4:38 Daniel Turini 16-Nov-01 4:38  This is a common error: TRUE and FALSE are for type BOOL true and false are for type bool Try making them consistent and the warning will go away.

Getting IP from a broadband router #realJSOP16-Nov-01 0:53 #realJSOP 16-Nov-01 0:53  My ISP (roadrunner) uses DHCP to assign IPs to its customers. My cable modem is connected to a router which is in turn connected to a hub with several machines connected to it. When I log ontot the router, it can provide me with the IP address assigned by the ISP. Does anyone know of a way to retrieve this IP address WITHOUT using the web browser? It's a Linksys BFRS-4 router by the way. Thanks in advance.

If so, set the gateway on your machine to the router IP. And, make sure that your router, and your cable modem are on different subnets, so that the DHCP in the router can assign your PC's IP at boot time. *Maybe Frank Re: Getting IP from a broadband router #realJSOP16-Nov-01 4:37 #realJSOP 16-Nov-01 4:37  I think you mis-understood my question. Here's the setup ISP --> (mystery IP) router (192.168.1.1) --> my LAN I want to programatically find out what the "mystery IP" (assigned by my ISP) is from *MY* side of the router (a computer on my LAN).

I think that tracert shows your side IP address if you use this from your comp. On the other hand, if we use this from ISP side, we get the different IP address to the same machine. However, the true router has the two NIC cards like the incoming packet side and the outgoing packet side? So, your LinkSys router may work just like Swith? If your LinkSys includs the agent of SNMP, you can get IP address from Agent. Have a nice day! -Masaaki Onishi- Re: Getting IP from a broadband router Anders Molin16-Nov-01 9:05 Anders Molin 16-Nov-01 9:05  You are talking about the IP of the external interface on your router, right? AFAIK you are running Linux, which actually might solve your problem At a work I had a couple of years ago we found out a funny thing, you can use two different protocols to traceroute. ICMP and UDP, one of the protocols shows the internal IP, the other shows the external IP of routers. I can't remember which one shows what. Linux uses UDP, as default, for traceroutes, and Windows uses ICMP, but on Linux you can vrite traceroute -i and it uses ICMP. Try with both ICMP and UDP and check if your router shows different IP's... - Anders Money talks, but all mine ever says is "Goodbye!"
