Change font of CFileDialog ? dlhson15-Jul-02 7:15 dlhson 15-Jul-02 7:15  1. How can I change font of a CFileDialog in MFC application and OPENFILENAME in Win32 Application ? Hung Son A Vietnamese student i-g.hypermart.net dlhson2001@yahoo.com Socket problem ? dlhson15-Jul-02 7:13 dlhson 15-Jul-02 7:13  In MSDN, I found a samples: ChatSvr and Chatter. That is a network application using CSocket. But I don't know how to use CSocket in multithread. In ChatSvr, I want to throw each client connecting to server to a particular thread. It means server will manage each client ( and his socket) in 1 thread. How can I do that ? I imagine the code for solving this problem may be like this: void CServerDoc::ProcessPendingAccept() { CClientSocket* pSocket = new CClientSocket(this); if (m_pSocket->Accept(*pSocket)) { pSocket->Init(); m_connectionList.AddTail(pSocket); //Add this line: m_threadList.Add(....); //or AfxBeginThread(....); } else delete pSocket; } Hung Son A Vietnamese student i-g.hypermart.net dlhson2001@yahoo.com Region into a polygon? phruby15-Jul-02 7:13 phruby 15-Jul-02 7:13  I've created two regions with the CRgn class and the function CreatePolygonRgn. I then use the CombineRgn function to take the intesection of the two regions created with CreatePolygonRgn. I now need to turn the resulting region into a polygon. I've been trying to use the GetRegionData function to return the points that make up the region. But I'm not having a success. The function keeps returning NULL for the RGNDATA pointer. Here is what I did: RGNDATA* pRgnData; x=aRgn.GetRegionData(NULL,1); y=aRgn.GetRegionData(pRgnData,x); pRgnData is still NULL. What am I doing wrong? Re: Region into a polygon? Scott H. Settlemier15-Jul-02 10:06 Scott H. Settlemier 15-Jul-02 10:06  YOU've got to allocate the buffer into which OS will put the region data. If you pass it your null pointer, it will tell you how space you should allocate for the buffer. The example above is passing an undefined pointer. e.g. DWORD x=aRgn.GetRegionData(NULL,1); RGNDATA* pRgnData=(RGNDATA*)malloc(x); DWORD y=aRgn.GetRegionData(pRgnData,x); Re: Region into a polygon? phruby15-Jul-02 10:21 phruby 15-Jul-02 10:21  Thanks Scott. I'll try that. Paul Print something graphical on a printer Qadddd15-Jul-02 7:05 Qadddd 15-Jul-02 7:05  Hello, As I still have problem to print my MSChart ActiveX, I should have several work around: 1) Use the MsChart.EditCopy to copy my graph in the clipboard in a metafile format and print it from clipboard 2) capture the part of the dialog screen containing my graph and print it But the question remains the same : how do I print a graphical object ( or a metafile or directly a MSChart) ? And with solution 2), how do I capture this part of my screen, under which form and how do I print it ? Thanks in advance for your help DD Re: Print something graphical on a printer Mike Nordell15-Jul-02 20:11 Mike Nordell 15-Jul-02 20:11  Qadddd wrote: But the question remains the same : how do I print a graphical object ( or a metafile or directly a MSChart) ? A graphical object can be selected into a DC. Just blit it to the printer DC. A metafile can be played back to a DC using PlayEnhMetaFile. Re: Print something graphical on a printer Qadddd15-Jul-02 21:15 Qadddd 15-Jul-02 21:15  hello, to be clear in my mind, do you have any code example that perform this kind of operation. I have to say that I am not a specialist in VC++ and that playing with printers (apart some easy prints in text mode) is quite new for me. I looked on the web and found no example for metafile play on a printer DC, they are all destinated to a rect, so a screen so it seems that I can't use this solution. No solution for the screen capture in a rect object that could be printed ? Thanks in advance DD Re: Print something graphical on a printer Mike Nordell16-Jul-02 8:02 Mike Nordell 16-Jul-02 8:02  Qadddd wrote: I have to say that I am not a specialist in VC++ You don't have to be.

I am not a specialist from the web neither, i use google and then jump in the thousands links or post some question on forums after having searched for a solution in already existing posts. What's the right phrase to print in vc++ an chart produced by an activeX Mschart?

It is simple, when I want to find something in MSDN, I never find it. Print for example, there is no simple doc explaining the right way to do it with a good significative example (at least when you search with their "search for"). another thing, I am coding in vc++, I don't give a damn about article talking of VB or other . Try to find out how to print chart produced by using a MsChart activeX, the only info I found is for VB. Try to search in the newsgroup, this question appear several times for at least 2 years, but there is no answer neither from students nor from microsoft ... Frankly, I don't understand why there is no "Print" method as there is an "EditCopy" method ... or at least the explanation to do it. DD how to convert int to CString?? EBerlin15-Jul-02 7:06 EBerlin 15-Jul-02 7:06  the only command I know if is itoa and that requires a second or third convesion before I end up with a MFC useable CString. I read a post saying something about using the Format command but I have been unable to get it to work. Can anyone help? Thanks Eric Re: how to convert int to CString?? Chris Losinger15-Jul-02 7:07 Chris Losinger 15-Jul-02 7:07  CString str; int i = 100; str.Format("%d", i); that's it. it's just like printf/sprintf. -c To explain Donald Knuth's relevance to computing is like explaining Paul's relevance to the Catholic Church.

NOT ReplaceSel or SetWindowText... Only Add in the end of the current text... Thanks world !!! Hello World!!! from Raphaël Re: Add text in CEdit Roman Fadeyev15-Jul-02 7:00 Roman Fadeyev 15-Jul-02 7:00  As stupidly it sounds, but Read old text, add your String to it, and write String back. For example CString s; MyEdit.GetWindowText(s); s+='abcd'; MyEdit.SetWindowText(s); It is a unique way. If you want to save caret position, do it manually. The better way is to write own heritable controls as CEditEx, CListBoxEx, and to place all needed routines like that into them. You will make it once and will be happy many years. Re: Add text in CEdit Raphael Kindt15-Jul-02 8:10 Raphael Kindt 15-Jul-02 8:10  I think that's a good idea... CEditEx... Yes... I'll do that... But I'll use (Nevertheless) this method: MyEdit.SetSel(-2, -1); MyEdit.Replace(MyText); Thank you very much Hello World!!! from Raphaël MDI Child Windows sbelow15-Jul-02 6:13 sbelow 15-Jul-02 6:13  Please Help, very little experience with MDI apps!! I'm looking for information regarding opening, closing, initializing data, etc.. in an MDI application. I want to be able to open a child window and initialize the fields with data from other apps. I can currently open the MDI application and initialize it with the information in shared memory, but I would like to be able to keep the MDI app open and just open different child frames with the data that I send over from other apps. The opening my already defined view part is throwing me. I found and example on creating a new view but nothing on an already defined view. Again I am new at MDI apps and looking for good information on dealing with the different child frames. Thanks in advance for any help that you can provide. Steve how do l plot graphs in MFC citress15-Jul-02 5:37 citress 15-Jul-02 5:37  Hi, l am writing a GUI using MFC, and l need to include some graphical features in it. Does anyone know how to plot graphs using MFC? All l need is something that plots points from a table of data, not from a function. It also doesn't need to be interactive -- basically l need just the most simple kind. Any suggestions will be appreciated. Thanks!! Re: how do l plot graphs in MFC Raphael Kindt15-Jul-02 8:41 Raphael Kindt 15-Jul-02 8:41  Type in search: "PGL" It's wonderfull P.G.L. = Plot Graphic Library Or go there : Plot Graphic Library (it's the same result) Hello World!!! from Raphaël Registry backup/restore esapp42015-Jul-02 5:12 esapp420 15-Jul-02 5:12  I would like to write a routine to copy registry entries into an INI file then back into the registry, but the only functions I can find in CWinApp are WriteProfile and GetProfile. Does anybody know if there is anything built-in for this task or if it must be done manually?? Any suggestions are appriciated. Thanks! Is it football season yet... GO GATORS!!! Re: Registry backup/restore Roman Fadeyev15-Jul-02 5:49 Roman Fadeyev 15-Jul-02 5:49  unfortunately, there is no any appropriate functions in MFC for your task. Moreover, MFC does not include any routines for INI-support (as far as i know). You must do it manually, by WinAPI functions. See in MSDN: RegOpenKey[Ex], RegCloseKey and so on for Registry operation AND GetProfileInt, GetProfileSection, GetProfileString etc. for INI-operations Re: Registry backup/restore esapp42015-Jul-02 5:55 esapp420 15-Jul-02 5:55  I was afraid of that. Oh well, doesnt seem all that difficult to do manually so thats what ill do! Thanks. Re: Registry backup/restore Roman Fadeyev15-Jul-02 6:05 Roman Fadeyev 15-Jul-02 6:05  There is an another way to solve your problem. You may use regedit with command-line params for saving and loading your data from reg-file. Like that regedit /e My.reg HKEY_CURRENT_USER\Software\My Data //From registry to file regedit -s My.reg //From file to registry You can use WINAPI - CreateProcess function to make this job silent
