Re: a non understandable debug error! Gérald Mercet5-Mar-02 4:04 Gérald Mercet 5-Mar-02 4:04  i've just read your post and i think that it's exactly the problem, because, when i arrive to pTabBinPort[0], i decrement again k so that it will be equal to -1. So, i will test it to see if it works; thanks a lot another debug error! Gérald Mercet5-Mar-02 4:52 Gérald Mercet 5-Mar-02 4:52  in fact in my code i change 2 things: for(i=1;i<=pow(2,m_dlgAsset)-1;i++) { k=m_dlgAsset-1; while(*(pTabBinPort+k)==1) { *(pTabBinPort+k)=0; Table.ConvertBinToNum(k,pTabBinPort,pTabNumPort); if(k!=0) k--; } *(pTabBinPort+k)=1; Table.ConvertBinToNum(k,pTabBinPort,pTabNumPort); *(pTabVar+i)=Table.CalcVar(pTabNumPort,m_dlgAsset); } you could see in the for statement that i going from 1 to pow(2,m_dlgAsset)-1 now and i've put a test in the while loop just for the case of k=0, so that we couldn't be in the situation of k=-1. But now i have another problem, when i test my application with m_dlgSector=30 and m_dlgAsset=15, at the end of the function i have another message error which says: Unhandled exception in CalcRiskport.exe (MFC42.DLL):0xC0000005:Access Violation. It's happened at this line: strValue.Format("%.5f",m_dlgValue); You could see the whole code in the precedent post. Re: a non understandable debug error! Nish Nishant4-Mar-02 23:08 Nish Nishant 4-Mar-02 23:08  You are not changing pTabBinPort anywhere are you? If you want to do some pointer arithmetic do it on a tmp pointer variable. Or it could be that you are overflowing the allocated memory Nish It's seven o'clock On the dot I'm in my drop top Cruisin' the streets - Oh yeah I got a real pretty, pretty little thing that's waiting for me Clear BREAK queu signal on serial port dejan.n4-Mar-02 22:57 dejan.n 4-Mar-02 22:57  I have a problem when I start to monitor the serial port for a BREAK signal. It seems that a situation occur when there are BREAK signals on "the queue". That is that if I trigger a BREAK signal just before I monitor the UART port this BREAK signal can triggers the program when I start to monitor the UART. There must be a way to clear the BREAK signal queue before I start to monitor the UART... How do I do that?? There is somethin called PURGE UART but this seem only to clear the TX and RX line, not the BREAK signal line. Please help!!

Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? Re: Clear BREAK queu signal on serial port dejan.n5-Mar-02 2:47 dejan.n 5-Mar-02 2:47  ehhh sorry about that. Do I feel lucky...well should I!? I hope so, cause I would be very VERY grateful if you let me know the answer to my problem. Help with document pointer Richard Everingham4-Mar-02 22:56 Richard Everingham 4-Mar-02 22:56  I am developing an MDI app. In this app I have two documents and one view for each document. Doc1 is persistant so there is only one instance of it period and that gets opened on startup by default. Doc2's view needs to be able to access a variable in Doc1. I can get a pointer to Doc1 in Doc2's view like so: Doc2view.h public: CDoc2* GetDocument(); CDoc1* GetDBDocument(); .... #ifndef _DEBUG inline CDoc2* CDoc2view::GetDocument() { return (CDoc2*)m_pDocument; } #endif #ifndef _DEBUG inline CDoc1* CDoc2view::GetDBDocument() { return (CDoc1*)m_pDocument; } #endif Now in Doc2's view I can access the pointer to Doc1 of cource like: CString Value; CDoc1* pDoc = GetDBDocument(); Value = pDoc->StoredValue; The problem is that does not point to the current instance of Doc1 for some reason. When I try and access the variable in Doc1 it returns nothing. In the above example Value would return nada. Please help I am a little new to MDI programming so this is confusing me. Thx, Richard Re: Help with document pointer Joaquín M López Muñoz4-Mar-02 23:02 Joaquín M López Muñoz 4-Mar-02 23:02  inline CDoc1* CDoc2view::GetDBDocument() { return (CDoc1*)m_pDocument; } Maybe I haven't understood your question, but this makes little sense. What type is m_pDocument? If it's not a CDoc1 *, forcing the cast will not covnert it into a CDoc1 *. Seems like you're treating m_pDocument either as a CDoc1 * or a CDoc2 *, depending on the situation. Could you clarify this? Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Help with document pointer Richard Everingham4-Mar-02 23:12 Richard Everingham 4-Mar-02 23:12  Sorry if the above is cofusing I will try and clarify: What I did basicly was just copy the GetDocument function for Doc2view and modify the names in hopes it would get me the pointer for Doc1 in the same way it gets it's own document pointer. Maby it would be better to ask this: How do I get a pointer to a document? In my app there are two documents with each one having it's own view. I just need to be able to access a variable in the first document from the second documents view. Thx, Richard Re: Help with document pointer Joaquín M López Muñoz4-Mar-02 23:30 Joaquín M López Muñoz 4-Mar-02 23:30  OK. Check Michael Moser's Managing MDI childs with MFC - how to trick the Document View model. I think you can adapt the function GetAllDocuments given there to suit your needs.

Thx, Richard advanced formatting static/listctrl columns peterchen4-Mar-02 22:14 peterchen 4-Mar-02 22:14  Hi! I'm looking for a static-like control supporting some advanced formatting (like superscript, subscript, and some special chars like sqrt, square, to-the-power-of 2, ttpo n , greek letters, etc.) Should work with ATL if possible, and I'd like to avoid using bitmaps and hosting IE for several reasons, and I can't use unicode in all cases. Any ideas? Any controls you know? Same would be cool for report view list ctrl columns - but I guess I'm already stretching the topic... Thanks Peter Re: advanced formatting static/listctrl columns Joaquín M López Muñoz4-Mar-02 22:22 Joaquín M López Muñoz 4-Mar-02 22:22  Aren't the formatting capabilities of CRichEditCtrl enough for your needs? By selectively changing the font you can have the greek and math symbols. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: advanced formatting static/listctrl columns peterchen4-Mar-02 23:37 peterchen 4-Mar-02 23:37  Yep, RE ctrl would do it; however there's still the make it non-selectable, default cursor etc, no scroll bars etc. But I'll give it a try. (And it doesn't help with listr ctrl columns - I hoped to rip off the code for some custom drawing...) Re: advanced formatting static/listctrl columns Andy Latham8-Jan-03 23:57 Andy Latham 8-Jan-03 23:57  Hi, Did you ever find a control that did this, i need a similar thing and would like to avoid writing it myself.

Neha4-Mar-02 20:47 Neha 4-Mar-02 20:47  Hi, Does anyone knows to calculate the file size with the parameters width ,height & resolution for a .jpg,.tif,.psd,.pcx file formats? Thanks Neha Re: File size calculation .. Joaquín M López Muñoz4-Mar-02 21:54 Joaquín M López Muñoz 4-Mar-02 21:54  Hi Neha. All of the formats you list have some compression feature, which means it is in general impossible to know how much a file will occupy without actually creating it. Also, some of the formats include some sort of "quality" parameter that controls the tradeoff between visual similarity to the original and file size. In view of this, the best you can have is an estimation of how much the file size will be. This is a hard problem and I don't think any conclusive answer exists for the formats you're interested in. If you're only concern is preallocating some memory so that the compression algorithms will not run out of space, you can assume in general sizecompressed <= sizeoriginal + Ksafeguard. Values of Ksafeguard as small as 10 KB are usually enough. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
