Hotkeys and threads Tanya2-Jan-01 18:45 Tanya 2-Jan-01 18:45  Hello, I am trying to incorporate the use of shortcut keys, such as F2, F3 etc into my application. I would like these shortcuts to apply to the parent window (ie, View or "main" dialog - ie "popup" style, not child) which currently has focus. I realise that to do so might require having each "Main Window" (the level at which I want to distinguish for shortcuts) in a seperate thread. I have tried using RegisterHotKey in a FormView which works OK, except even if I create a child dialog in a seperate thread, registering another hot key with the same VK_ gets ignored (when the dialog has focus) and the View hotkey processed? I would have hoped being in a seperate thread would render the hotkey "different" from the other registered in the FormView? If anyone could tell me where I am going wrong, or can provide any alternative suggestions, it would be greatly appreciated. Thanks, Tanya Low level database routines for win32 (not DB classes) 2-Jan-01 7:49 2-Jan-01 7:49  As a former (and current) UNIX programmer, I am finding myself in a state of confusion when it comes to DB programming in windows. Maybe you have to, that's why I'm asking this here. In UNIX I get the libraries I need to talk to the database and use SQL statements to do it all. I connect, query, then parse the results. I'm looking for something as simple to do under Windows. If it helps, I'm looking for something very php (www.php.net) like in syntax: connect(params), execute(sql statement), fetch_array(results), disconnect(). Most important no note that the fetch_array returns tabel data as record=fetch_array(query_result); record[field]="some val". Alternative to that is fetch_row which you can use the index (column number) of the field to get that value. Is there anything like that in Microsoft? Do I have to use classes of CDatabase and CRecordset? It looks like I have to jump through a lot of hoops to get something simple working. Secondly, what are the installation requirements for the particular methods? Must I always require Microsoft Access be installed? Under UNIX I can make such a requirement because there always is a UNIX admin handy to install it. But on a PC I cannot make that assumption. I have to assume that any inexperianced user can handle it. Which also raises the question, how do I initialize a database under windows? Could I use hard coded SQL statements? Thanks in advance AnimateWindow() does not work 2-Jan-01 7:04 2-Jan-01 7:04  I'm having a nasty time with AnimateWindow(), on Win2K SP1, using VC++ 6 and ATL/WTL. The function always fails, and GetLast Error() returns 8 (Not enough storage space to execute the command). I am handling WM_PRINT and WM_PRINTCLIENT; my breakpoints in those handlers are never hit. The dialog that I am painting is bitmap-based, but again, my paint handlers are not called, so I can't see how that would influence things. I jusy tried the same thing with a simple dialog, and no luck - I get an error code 6 (invalid handle) which is ridiculous, since th ehandle is valied (as demonstrated by a call to ShowWindow()).

HELP: Create(IDD_DIALOG,NULL) does not return 2-Jan-01 2:11 2-Jan-01 2:11  After Creating the dialog with Create(IDD_DIALOG_NAME,NULL) the function does not return (deadlock). I have created a dialog with the same resource once before and everything works fine. But the second time I try to create it the function does not come back. It is important that I create a new thread in both cases. The dialog I want to load uses an Avi.

Can I use CBT Hooks to gain control over most everything? I know about policies and they are not sufficient for what I need.

It seems a lot different from a Doc/View architecture. Can anyone give advice on how MS Money 2001's gui was designed? The only thing that looks "Visual C++ wizard" generated is the menu at the top. I have only used the Visual C++ MFC.exe wizards and modified things from there as necessary, but very limited. I figure I've got a few weeks to learn the desired gui structure before the project begins. Thanks! Scott! Still learning, but getting better! How to open and change an image in a window? 1-Jan-01 5:56 1-Jan-01 5:56  Hi Everybody: I wanted to open an image(prefferably in TIFF form, but not necessarily) in a window, and draw some lines on the image?(Using VC++ MFC Application) I 'd really appriciate any help. thank-you. Sadegh. Re: How to open and change an image in a window? Christian Graus2-Jan-01 19:55 Christian Graus 2-Jan-01 19:55  You basically want to download paintlib ( www.paintlib.de ) to read the tiff, then select the image into a DC and use MoveTo and LineTo to draw your lines.

A friend had a book once, I think titled "Advanced Multimedia Programming". I guess it has some demo apps w/source for that thing. Unfortunately I don't recall the website of the author today! But let me search in my old papers maybe I come up with something!

TIA, - Anders converting char to bstrVal 31-Dec-00 11:57 31-Dec-00 11:57  Heres a hard coded sample of assigning "Hello" to this variant bstr value. How would I assign a char* or char[] to bstr? char *cTemp="Hello"; char cTemp2[32]="Hello"; VARIANT v; v.vt = VT_BSTR; v.bstrVal = SysAllocString(OLESTR("Hello"));//work ok // how would I assign these? v.bstrVal = cTemp; v.bstrVal = cTemp2; Re: converting char to bstrVal Anders Molin31-Dec-00 12:55 Anders Molin 31-Dec-00 12:55  There might be smarter/better ways to do it, but the following code works char *t = "just testing"; CComBSTR bs; bs.Append(t); VARIANT v; v.vt = VT_BSTR; v.bstrVal = bs; - Anders Re: converting char to bstrVal Michael Dunn31-Dec-00 16:25 Michael Dunn 31-Dec-00 16:25  You don't assign a char* to a BSTR, because a BSTR is not a C string. If you want to create a BSTR from a char array, use an ANSI<->Unicode conversion function, for example T2OLE: #include <atlconv.h><br /> <br /> V.bstrVal = SysAllocString ( T2COLE(cTemp) ); --Mike-- http://home.inreach.com/mdunn/ "That probably would've sounded more commanding if I wasn't wearing my yummy sushi pajamas."   --Buffy Re: converting char to bstrVal 1-Jan-01 15:46 1-Jan-01 15:46  Thanks I found the follwoing seems to work... var.bstrVal = (_bstr_t)cTemp;
