Thanks for your awnser Resizing image right bottom? Dominik Reichl21-Jul-03 7:26 Dominik Reichl 21-Jul-03 7:26  Hello, I have a dialog-based application which supports resizing of its windows. The resizing works very well, it's just a visual thing I am looking for: the resizing "image" on the right bottom. For example open Internet Explorer and have a look bottom right. There are diagonal 3D lines, overlapping the status bar, which show that the dialog is resizable. Do you know how to show these diagonal 3D lines? Thanks -Dominik _outp(0x64, 0xAD); and __asm mov al, 0xAD __asm out 0x64, al do the same... but what do they do?? Re: Resizing image right bottom? J. Dunlap21-Jul-03 8:17 J. Dunlap 21-Jul-03 8:17  In your WM_PAINT handler, do this: DrawFrameControl(hdc,rect,DFC_SCROLL,DFCS_SCROLLSIZEGRIP); rect should be the rectangle where you want the frame control to be, and hdc should be the HDC of your window.

Dominik Reichl21-Jul-03 9:28 Dominik Reichl 21-Jul-03 9:28  The frame control is drawn now (the background isn't erased correctly, so if you have a source snippet send it to me, I am not that GUI expert ), but the background of the frame control is always the standard gray. The problem is now that my application uses a custom background color... I tried to change the background color for the frame control using dc.SetBkColor and/or dc.SetBkMode(TRANSPARENT), but nothing worked, the gray background is drawn independently of what I set as DC background... How can I make the frame control background drawn as the same as my main dialog background color?

Problem handling WM_NCPAINT using XP visual style khb21-Jul-03 7:12 khb 21-Jul-03 7:12  Hi! I wrote an application where I draw an additional button to the caption of a dialog. This works perfectly for all versions of windows, even for XP when the "classic style" is used. But, if I select an XP theme, I run into a problem: When I handle the WM_NCPAINT message, the caption of the dialog (and also the frame) is not drawn using the corresponding visual style, it is drawn in "classic style"! This looks really ugly. My SDK is up to date. I tried it with and without a manifest file, it makes no difference. I develop the code under win2k, using vc6. Maybe this is the problem: does anybody know, if this works correctly with vc7? If anybody has an idea how to solve this problem, please help. I've been trying it for two weeks now any I'm out of ideas... Thanks in advance, Marcus. Re: Problem handling WM_NCPAINT using XP visual style Michael Dunn21-Jul-03 14:06 Michael Dunn 21-Jul-03 14:06  AFAICT this is By Design(tm). Since themes change the look of the non-client area, when an app handles WM_NCPAINT (also to change the look of the non-client area), XP turns off the theme so the app's own painting takes precedence. Look at RealPlayer 8 for another example. --Mike-- "Big handwavy generalizations made from a position of deep ignorance is one of the biggest wastes of time on the net today. -- Joel Spolsky Ericahist | Homepage | RightClick-Encrypt | 1ClickPicGrabber Re: Problem handling WM_NCPAINT using XP visual style khb21-Jul-03 20:33 khb 21-Jul-03 20:33  Thank you for the answer, Mike. Is it possible, to draw the nonclient area by hand using the correct theme? I know that I can use GetSystemMetrics() to get all dimensions I need. I also know that I can load the theme elements from the uxtheme.dll. But, I'm not sure how to apply them to the window. Do you know how to do that? Any code fragments, links to descriptions or articles would help, too. Thanks again, Marcus. Multiple modal dialog boxes Deepak Samuel21-Jul-03 7:11 Deepak Samuel 21-Jul-03 7:11  Hi, I need to create about three to four modal dialog boxes such that when a button is pressed in the first one it leads to the next and again when a button is pressed in this it leads to the next one and so on..I am a novice in this field and I need some help in this. I tried this: void CNewoneDlg::OnOK() { CDialog aboutDlg(IDD_DIALOG1); INT_PTR pRet=-1; aboutDlg.DoModal(); //CDialog::OnOK(); (I tried taking this off...but didnt work either) } This works..it leads to the next dialog box on pressing ok.. but.. void CDialog1Dlg::OnOK() { CDialog aboutDlg(IDD_DIALOG2); INT_PTR pRet=-1; aboutDlg.DoModal(); //CDialog::OnOK(); } This doesnt lead to the next dialog box on pressing ok..I am confused, since I have used the method in the earlier function..when that can work, why cant (isnt) this? I desperately need a help..

Jens Doose21-Jul-03 22:25 Jens Doose 21-Jul-03 22:25  Well, there are no casting routines. But you can use these conversion methods of CString: CString to BSTR: AllocSysString BSTR to CString : SetSysString Or you use the _bstr_t class declared in <comdef.h>, which is very comfortable. Jens std::sort() passes invalid parameter to sorting callback function s_k21-Jul-03 7:02 s_k 21-Jul-03 7:02  Hi, I use vector of pointers to my class to store data. I insert them using push_back(). Here is my function for inserting data into vector: [code] UINT CVirtualLWItemManager::insertItem(LS_item* pNewItem) { // check if current capacity is enough if (m_vecItems.size() > m_vecItems.capacity()) { AfxMessageBox("m_vecItems.size() > m_vecItems.capacity()"); return 0; } if (m_vecItems.size() == m_vecItems.capacity()) { // enlarge array m_vecItems.reserve(m_vecItems.capacity() + 128); // try again return insertItem(pNewItem); } m_vecItems.push_back(pNewItem); return 1; } [/code] Here is my function that launches std::sort(): [code] void CVirtualLWItemManager::sortItems(INT (*sort_cb)(LS_item*, LS_item*)) { std::sort(m_vecItems.begin(), m_vecItems.end(), sort_cb); } [/code] And here is my static sorting callback function: [code] INT CMyFileView::sortCallback(LS_item* pDataFirst, LS_item* pDataSecond) { ITEM_DESC* param1 = NULL; ITEM_DESC* param2 = NULL; param1 = (ITEM_DESC*) pDataFirst->lParam; param2 = (ITEM_DESC*) pDataSecond->lParam; INT iSortColumn = 0; if (getDoc()->iViewToSort == 1) iSortColumn = getDoc()->SortingColumnLeft; else iSortColumn = getDoc()->SortingColumnRight; // Nejdrive (..), pak adresar, dale soubor if (param1->folder > param2->folder) return -1; else if (param1->folder < param2->folder) return 1; // Trizeni podle zvoleneho sloupce switch (iSortColumn) { // ASCENDING case 0: // Podle nazvu souboru a adresaru return param1->name.CompareNoCase((LPCTSTR) param2->name); case 1: // Podle velikosti if(param1->size < param2->size) return -1; if(param1->size > param2->size) return 1; break; case 2: // Podle data if (param1->date < param2->date) return -1; if (param1->date > param2->date) return 1; break; // DESCENDING case 3: // Podle nazvu souboru a adresaru return (param1->name.CompareNoCase((LPCTSTR) param2->name)) * -1; case 4: // Podle velikosti if (param1->size < param2->size) return 1; if (param1->size > param2->size) return -1; break; case 5: // Podle data if (param1->date < param2->date) return 1; if (param1->date > param2->date) return -1; break; } return 0; } [/code] The problem is, sometimes pDataSecond parameter passed to this function has invalid parameter, eg. 0xfdfdfdfd. How is it possible? Objects that are inserted to the vector are created on the heap. Thank you a lot for any suggestion. Re: std::sort() passes invalid parameter to sorting callback function Joaquín M López Muñoz21-Jul-03 7:18 Joaquín M López Muñoz 21-Jul-03 7:18  At first sight, there're two problems with your code. The first one is not critical, but anyway: The comparison if (m_vecItems.size() > m_vecItems.capacity()) is always false, so there's no point in checking it. By definition, the size of a vector canot be larger than its capacity. As for if (m_vecItems.size() == m_vecItems.capacity()) it is not really necessary (vectors grow as necessary automatically), but it can improve performance, so no problem about it. The real problem (I guess) is that sort expects a comparison predicate that has less-than semantics, i.e. it expects it to return true is the first argument if less than the second, and false otherwise. Your sortCallback has (<0,0,>0) semantics: change it to what I've indicated and things will probably start to work OK. Good luck. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: std::sort() passes invalid parameter to sorting callback function s_k22-Jul-03 2:30 s_k 22-Jul-03 2:30  It works! I just changed return value of the sorting callback from INT to bool, and replaced 1, -1, 0 with true and false and it's ok now. Thank you Joaquín, you helped me very much! Detect USB Port Version? nng3821-Jul-03 5:57 nng38 21-Jul-03 5:57  How to detect that your PC system has USB version 1.1 or 2.0 using Visual C++? Thank you very much Re: Detect USB Port Version? John M. Drescher21-Jul-03 6:14 John M. Drescher 21-Jul-03 6:14  Did you know that the standards committee wants to allow makers of USB 1.1 products to rename their product to be USB 2.0 without adding support for the faster speeds? I am not sure how this will affect your results but I wanted to inform you of this. I'll try to find the links.. Here is part of the article on the register (www.register.com): The trade group responsible for marketing the USB peripheral interface has the older given 1.1 specification a speed-boost -simply by changing its name. Of course 1.1, superseded by the much speedier 2.0 specification, hasn't really got any faster. But the USB Implementors Forum (USB-IF) has decided that vendors can describe USB 1.1 ports as USB 2.0 ports. Now they can describe the old specification as "Full Speed" and the newer, 2.0 specification as "High Speed." The Bangkok Post notes that this puts vendors in breach of EU trades description legislations. Whoops. USB 2.0 was never intended to be branded with a version number. Instead, the USB-IF dubbed it 'Hi-speed USB'. USB 1.1 was to be known as plain old 'USB'. Manufacturers have nevertheless insisted on sticking with the version numbers, which is what seems to have cause all the trouble. Apparently consumers were shunning older models. "I now understand the new full-speed and high-speed naming, but what is going to happen when USB 3.0 is released? Is it going to be 'Really High Speed'?," asks an editorial in GeekNews It's not the first bit of semantic ethnic cleansing we've seen this year. A handful of vendors have hijacked the 4G bandwagon, hoping that this will put them in the driving seat when the real 4G specification is passed.
