CImageList and the System ImageList? 17-Jul-01 2:38 17-Jul-01 2:38  Hi all, Sorry to keep asking stupid questions, but I am very new to MFC and don't have any good reference books yet. I want to attach to the system image list in 9x / NT to display OS icons in a CListView. I've got the system imagelist handle from a call to SHGetFileInfo(...), the only way I know how, and now I want to attach it to a CImageList, but the HIMAGELIST parameter appears to be a structure of some type and I can't find any useful declarations of it in the header files. So, the question simply is; How to I attach to the system image list?? Thanks. Jonathan Thorpe. Re: CImageList and the System ImageList? Tomasz Sowinski17-Jul-01 2:42 Tomasz Sowinski 17-Jul-01 2:42  Use CImageList::Attach if you have HIMAGELIST already. Tomasz Sowinski -- http://www.shooltz.com Re: CImageList and the System ImageList? 17-Jul-01 4:44 17-Jul-01 4:44  That's the problem, SHGetFileInfo(...) doesn't return a HIMAGELIST, it returns a DWORD that is the handle of the system imagelist. The only way to make Attach(...) accept it is to cast it to HIMAGELIST, which works fine, but the imagelist contains 0 images (so I don't reckon it worked), although I now have no icons on the start menu anymore!! Anymore ideas? Is there a way to get a handle to the system imagelist via MFC that will return the necessary HIMAGELIST or a pointer to a CImageList object? Jon. Re: CImageList and the System ImageList? Tomasz Sowinski17-Jul-01 4:53 Tomasz Sowinski 17-Jul-01 4:53  Just cast the value returned by SHGetFileInfo: // C style HIMAGELIST hImgList = (HIMAGELIST)SHGetFileInfo(...); // C++ style HIMAGELIST hImgList = reinterpret_cast<HIMAGELIST>(SHGetFileInfo(...)); Tomasz Sowinski -- http://www.shooltz.com Re: CImageList and the System ImageList? Michael Dunn17-Jul-01 7:08 Michael Dunn 17-Jul-01 7:08  although I now have no icons on the start menu anymore!! That's because you didn't detach your CImageList from the image list, so the CImageList destructor destroyed the underlying image list. Or you were using a list control and it didn't have the LVS_SHAREIMAGELISTS style, so when the control was destroyed, it destroyed the image list. Oops! Bye-bye icons. You'll need to reboot to fix that. --Mike-- http://home.inreach.com/mdunn/ Sometimes, arming yourself with a big pointy stake just won't do you any good. Re: CImageList and the System ImageList?

Is MSVC++ Standard C++ ernst.maurer17-Jul-01 2:06 ernst.maurer 17-Jul-01 2:06  Hi I will want to know: is latest version of VC correspond ISO C++ Standard? Ernst Re: Is MSVC++ Standard C++ James Brown17-Jul-01 8:37 James Brown 17-Jul-01 8:37  No, VC 6.0 is not ISO compliant. Nor will the new version be when Visual Studio NET is released, although it should be alot better than the current version. Bear in mind that there aren't many ISO C++ compilers available - In fact I don't believe that there are ANY ISO C++ compilers, but I'm sure someone will correct me if I'm wrong. James Re: Is MSVC++ Standard C++ Erik Funkenbusch17-Jul-01 13:18 Erik Funkenbusch 17-Jul-01 13:18  The "latest" version of VC++ is 3 years old, and was never intended to be ISO compliant (since the standard wasn't finished when it was written). VC7 will be much closer, but will still lack a few important features like Partial Template Specialization. They claim that VC8 will have a heavy standards focus, and that it won't take 3 years for it to reach the light of day Drag Files into program #realJSOP17-Jul-01 1:58 #realJSOP 17-Jul-01 1:58  We have an app which is associated with graphic files (jpg, bmp, etc). When we drag files of these types over the app and drop them on the mainframe, the app opens an appropriate view. We also have a document template that allows us to view/edit simple ascii text files. When I drag a .TXT file over the app and drop it, it tries to open a view of the wrong type (a graphics view). I've tried handling the WM_DROPFILES message in CMainFrame, but the code is never executed. Does a file extension *HAVE TO BE* associated with the app before I can successfuylly drag a file into the app? Re: Drag Files into program Simon Capewell17-Jul-01 2:29 Simon Capewell 17-Jul-01 2:29  Make sure the window has the extended style WS_EX_ACCEPTFILES set. Alternatively you can use DragAcceptFiles. Re: Drag Files into program Tomasz Sowinski17-Jul-01 2:34 Tomasz Sowinski 17-Jul-01 2:34  Does a file extension *HAVE TO BE* associated with the app before I can successfuylly drag a file into the app? I don't think so. I've just successfully dropped .txt file into my MFC app that doesn't even have a template for such files (of course, I've got parsing error, because program doesn't read plain text). Can you post relevant parts of CYourApp::InitInstance (especially, the AddDocTemplate calls) ? Tomasz Sowinski -- http://www.shooltz.com Re: Drag Files into program #realJSOP18-Jul-01 1:27 #realJSOP 18-Jul-01 1:27  In InitInstance(), I have this: DragAcceptFiles(TRUE); EnableShellOpen(); RegisterShellFileTypes(TRUE); I added a handler for the WM_DROPFILES message, but it never gets into that message handler function. I think it might be Stingray's code that's interfering. Re: Drag Files into program Tomasz Sowinski18-Jul-01 1:48 Tomasz Sowinski 18-Jul-01 1:48  In InitInstance(), I have this: In fact, I was expecting AddDocTemplate calls Anyway, if the doc is opening but the type is wrong, put the breakpoint in CDocTemplate::MatchDocType (mfc\src\doctempl.cpp, line 186 on VC6 SP5) - this method is called by MFC when file is dropped onto mainframe. Matching is done by comparing file extensions - you'll be able to see exactly what's going on. Have no idea on Stingray's impact.

CDatabase / SQLExecute / Finding ID Jimmy Ehrnström16-Jul-01 23:15 Jimmy Ehrnström 16-Jul-01 23:15  What I am trying to do is do is to add a new entry to a database table with an SQL insert-statement, and then find the, by the DBMS, auto-assigned id for the new entry. So far I've managed to accomplish this by first using the SQLExecute command, followed by a select-statement to identify the id of the new entry. Unfortunately I've stumbled across a table containing lots of dublicates, where I've found no way to uniquely identify the new entry using a select- statement. Is there any other way than using a select-statement to find the id for my new entry? The only one I can think of is looking for the highest id in the table, and assume that this is the id I'm looking for. This, I feel, is kind of risky though, since I'm not sure about how id's are assigned in the DBMS (Microsoft SQL Server). If the DBMS decides to start reusing lower order id's my program would stop functioning correctly. Any advice would be much appreciated. Thanks, Jimmy Ehrnström Re: CDatabase / SQLExecute / Finding ID Tomasz Sowinski16-Jul-01 23:23 Tomasz Sowinski 16-Jul-01 23:23  SQLServer has system variable @@IDENTITY that returns the last-inserted identity value. Tomasz Sowinski -- http://www.shooltz.com Re: CDatabase / SQLExecute / Finding ID Jimmy Ehrnström17-Jul-01 22:23 Jimmy Ehrnström 17-Jul-01 22:23  Thanks, but I still can't get it to work. @@IDENTITY returns NULL and not an id. I've read all information about this I could find but found no explanation of what's wrong. Here's a sample of my code: pDB->ExecuteSQL(sql); CRecordset rs(pDB); if (rs.Open(CRecordset::snapshot, _T("SELECT @@IDENTITY"), CRecordset::readOnly)) { if (!rs.IsBOF()) { rs.MoveFirst(); CDBVariant dbId; rs.GetFieldValue((short)0, dbId); rs.Close(); if (databasId.m_dwType == DBVT_LONG) int entryId = databasId.m_lVal; } } Thanks, Jimmy Ehrnström java.lang.NullPointerException NormDroid16-Jul-01 22:25 NormDroid 16-Jul-01 22:25  I'm create IWebBrowser2 interface and when I Navigate2 to a particular web page I get a dialog box with "java.lang.NullPointerException..." messagebox.

I wrote a dll-based plugin for Winamp and it works fine until I close Winamp. When I do this Winamp crahes with an access violation. I have done some detailed debugging but it feels like a problem that might stem from my modest level of experience with DLLs. Any thought would be very valuable.
