To me, the output looks exactly the way you described it should look..... Could you edit your post and use the < PRE> tags if you are having a spacing problem - without the < PRE>tags, youd output looks just like you describe it.

Douglas A. Wright dawrigh3@kent.edu SetLayeredWindowAttributes in an ActiveX control Daed29-Sep-03 4:44 Daed 29-Sep-03 4:44  I am creating a button control and I want to set some parts of this button to be transparent. I am using SetLayeredWindowAttributes API but it is not giving any result. It returns FALSE value and when I get the last error I got “The parameter is incorrect”. Is there something wrong in what I am doing or may be this API does not work with controls? My code is as follows: int CMyButtonCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (COleControl::OnCreate(lpCreateStruct) == -1) return -1; SetWindowLong(m_hWnd, GWL_EXSTYLE, GetWindowLong(m_hWnd, GWL_EXSTYLE) | WS_EX_LAYERED); HMODULE hUser32 = GetModuleHandle(_T("USER32.DLL")); g_pSetLayeredWindowAttributes = (lpfn)GetProcAddress(hUser32, "SetLayeredWindowAttributes"); COLORREF col = RGB(255, 0, 0); BOOL bResult = g_pSetLayeredWindowAttributes(m_hWnd, col, 150, LWA_COLORKEY); if (!bResult) { LPVOID lpMsgBuf; FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, GetLastError(), MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language (LPTSTR) &lpMsgBuf, 0, NULL); AfxMessageBox((LPCTSTR)lpMsgBuf); } } Any ideas?

And what would be even better would be to wrap them in a class and provide operator overloads so you could just treat it like a regualr integer. something like class int64 { public: unsigned long hi; unsigned long lo; //whole bunch of operator overloads }; int64 i = 23; int64 h = 2234343433234; i++; i = h + i * 23; Anyone ever done anything like this? I haven't found much yet (though I'm still looking) ¡El diablo está en mis pantalones! ¡Mire, mire! Real Mentats use only 100% pure, unfooled around with Sapho Juice(tm)! SELECT * FROM User WHERE Clue > 0 0 rows returned Re: 64 bit integers KarstenK29-Sep-03 4:26 KarstenK 29-Sep-03 4:26  I do these with things with shifting ( << or >> ) but if you do a little more, its better to make a class. It helps to eliminate bugs. Try this @ home. (B&B) Re: 64 bit integers Jim Crafton29-Sep-03 4:54 Jim Crafton 29-Sep-03 4:54  how do you do the adding with the 2 32bit vals (hi and lo) using the shift operators? (sorry if this is a stupid question I've never done this) ¡El diablo está en mis pantalones! ¡Mire, mire! Real Mentats use only 100% pure, unfooled around with Sapho Juice(tm)! SELECT * FROM User WHERE Clue > 0 0 rows returned Re: 64 bit integers Anonymous29-Sep-03 4:26 Anonymous 29-Sep-03 4:26  64-bit integers are handled by the compilor, just use INT64 instead of int if you need to access the hi and lo parts, then I suppose, you could just define a union Re: 64 bit integers Jim Crafton29-Sep-03 4:53 Jim Crafton 29-Sep-03 4:53  Let me qualify: the solution needs to work on non VC compilers and cross platform. So using an INT64 is out. Plus even if you did, I don't think it will let you write INT64 num1; INT64 num2 = 48939434434343; num1 = 23 + 34 + num2; Will it? ¡El diablo está en mis pantalones! ¡Mire, mire!

Also, try searching the Net for ULARGE_INTEGER and see how it is handled. Five birds are sitting on a fence. Three of them decide to fly off. How many are left? Re: 64 bit integers Jim Crafton29-Sep-03 5:14 Jim Crafton 29-Sep-03 5:14  http://www.codeproject.com/cpp/cint96.asp is SOOO close to what I want. But when I looked at how PJ did it, he cheated!! He used the internal MS __int64 type to help with the math routines. Unfortunately I need to make this work on multiple compilers, so I can't use this. Damn. Oh well there are still some good ideas. Thanks ¡El diablo está en mis pantalones! ¡Mire, mire! Real Mentats use only 100% pure, unfooled around with Sapho Juice(tm)! SELECT * FROM User WHERE Clue > 0 0 rows returned Re: 64 bit integers Tom Pruett29-Sep-03 5:08 Tom Pruett 29-Sep-03 5:08  I remember Jack Crenshaw published 64 bit integer math library in Embedded System Programming several years ago. I don't think it was a class, just a typedef with basic math functions written in C. Good luck. If you find anything useful let us know. Re: 64 bit integers Jim Crafton29-Sep-03 5:14 Jim Crafton 29-Sep-03 5:14  I will, whatever I figure out I intentend to write an article on. ¡El diablo está en mis pantalones! ¡Mire, mire!

URGENT IrishSonic29-Sep-03 4:11 IrishSonic 29-Sep-03 4:11  Hiya I need some code to make my subitems in list control editable. I have downloaded code samples and tryed them all, to incorporate them into my project, but with all of them, it is a nightmare to get it in to work. I have the item and subitem index numbers. Can someone plz give me some simple code to edit the chosen subitem?? Thanks, IrishSonic. Re: Editable subitem code needed!! URGENT b_girl29-Sep-03 4:26 b_girl 29-Sep-03 4:26  I haven't been able to get this to work yet, but I know it does (my code is just messed up I think)... it's pretty simple to understand it if you read through it properly. http://www.codeguru.com/listview/edit_subitems.shtml[^] good luck (if you run into the same problem as me, see my recent post, and figure out how to fix it, please let me know!!) Re: Editable subitem code needed!! URGENT IrishSonic29-Sep-03 23:26 IrishSonic 29-Sep-03 23:26  Hiya b_girl. Thanks for that. That is some of the code I can't get to work for me. Will give it another go and let you know. IrishSonic Re: Editable subitem code needed!! URGENT b_girl30-Sep-03 3:17 b_girl 30-Sep-03 3:17  Sounds good. I'm still trying to get it to work for me as well, so if I get it, I'll let you know as well. Re: Editable subitem code needed!! URGENT b_girl30-Sep-03 5:12 b_girl 30-Sep-03 5:12  I have it basically working now (finally). In my application I never wanted to give the user the ability to edit the first column, only the second column (there will only ever be 2 columns in my app). So what I did was just remove the code that determines the column number, and replace it with just setting colnum = 1 So now, a user can click anywhere in the row (I have the extended style LVS_EX_FULLROWSELECT set) and the second column will be available for in-place editing. My only problem now, is it messes up on vertical scroll. I have removed the functionality for the horizontal scroll because I don't need it. But I can't figure out how to even get that vertical scroll function to be called. I'm not able to use the WM_VSCROLL message, and I think that's what I need to do, so I'm stuck again. If you're doing something similar to me (having 2 columns and only ever needing to edit the second one) and you're still needing a bit of help let me know. Re: Editable subitem code needed!! URGENT IrishSonic2-Oct-03 22:26 IrishSonic 2-Oct-03 22:26  Hiya b_girl Couldn't at all get the sample code to work for me. Tried for at least 3 days. Anyway went searching the net again and found a different example www.codeproject.com/listctrl/editing_subitems_in_listcontrol.asp Got this to work for me last night. For my project I did have to tweak it for my needs. The code is alot simplier than the other one and it is one of those projects that compiles and works. Nothing more annoying than downloading a project and it doesn't compile. You should definitely check it out. Re: Editable subitem code needed!! URGENT b_girl3-Oct-03 3:32 b_girl 3-Oct-03 3:32  Thanks. I did get the other bit of code to work almost perfect though... I just finished looking at the code on: http://www.codeproject.com/listctrl/editing_subitems_in_listcontrol.asp[^] It doesn't seem to handle the vertical scroll, and that's all I need to do now. The code I have works perfectly, unless the vertical scroll bar in the list control is hit during editing. Adding a new resource Rome Singh29-Sep-03 3:57 Rome Singh 29-Sep-03 3:57  I'm trying to add a new resource to my application which is in VC++ 7.0 SP1. Everytime I try to Insert or Add Resource the entire IDE shutsdown. Is anyone else experiencing this problem? RS another CListCtrl question b_girl29-Sep-03 3:51 b_girl 29-Sep-03 3:51  I have a dialog box, and within that dialog box I have a CListCtrl, report view, that is set up with 2 columns. I found code online (with the help of some people on this board) at http://www.codeguru.com/listview/edit_subitems.shtml[^] to help me with doing in-place editing of the items in the second column of this list control. For some reason, I can't get it to work in my project. I have a class for my dialog box, and a separate class for the list control. This code from the above link creates a handler for the WM_LBUTTONDOWN message. When going through the class wizard, I don't have the option of using this event, I have tried creating a handler for the NM_CLICK message, but it doesn't seem to do anything either. right now, I'm handling the messages in my CListCtrl class, not my dialog box class. Can anyone tell me why I don't have the WM_LBUTTONDOWN message available, and what I can do to get around that in order to make this code work? Thanks.
