Re: Hmm... I got another question Tomasz Sowinski14-Mar-02 9:49 Tomasz Sowinski 14-Mar-02 9:49  WM_NCCALCSIZE ? Tomasz Sowinski -- http://www.shooltz.com I tried that but... generic_user_id14-Mar-02 9:48 generic_user_id 14-Mar-02 9:48  "The WM_NCCALCSIZE message is sent when the size and position of a window's client area must be calculated. By processing this message, an application can control the content of the window's client area when the size or position of the window changes." - MSDN I know it must be possible, as the size of the Title Bar changes when the dialog is a 'Tool window' Can somebody please help me out? Some source code would be greatly appreciated. Re: I tried that but... Tomasz Sowinski14-Mar-02 9:58 Tomasz Sowinski 14-Mar-02 9:58  So what's the problem? Capture the message and return the client area small or big enough for given titlebar size. Tomasz Sowinski -- http://www.shooltz.com Re: I tried that but...

So my actual question is: Is there a way to hilight a row on a listcontrol without having focus? Re: clistctrl question Tomasz Sowinski14-Mar-02 3:15 Tomasz Sowinski 14-Mar-02 3:15  listCtrl.SetItemState(index, LVIS_SELECTED, LVIS_SELECTED); Tomasz Sowinski -- http://www.shooltz.com Re: clistctrl question jafrazee14-Mar-02 3:23 jafrazee 14-Mar-02 3:23  i have tried that but the row is only hilighted with the control has focus. as soon as focus is lost the hilight also goes away. would be greatful for anyother suggestions. thank you. Re: clistctrl question Tomasz Sowinski14-Mar-02 3:26 Tomasz Sowinski 14-Mar-02 3:26  Do you have 'Show selection always' option set in the dialog editor? If you're creating list control dynamically, use LVS_SHOWSELALWAYS style. Tomasz Sowinski -- http://www.shooltz.com Re: clistctrl question jafrazee14-Mar-02 3:30 jafrazee 14-Mar-02 3:30  that is exactly the problem. thank you very much. Drag and Drop Text sanskypotov14-Mar-02 2:50 sanskypotov 14-Mar-02 2:50  Hi , I am trying to create an editor similar to MS VisualStudio's Resource Editor for Dialog. In this I need to create a Label, which would contain Text and be dragged around and also be resized. Can some one tell me how it can be done. Thanks, Sansky Re: Drag and Drop Text Dave Glick14-Mar-02 8:31 Dave Glick 14-Mar-02 8:31  Howdy, I think you would need to override several mouse functions in your Label class to do the following: OnLButtonDown: Track when the user clicks and if they have the left button down so that you can know what to do when they move the mouse OnLButtonUp: Again, use this to remember the mouse button state OnMouseMove: Inside here test to find out if the mouse button is down and if so, use MoveWindow to move your window to the same coordinates as the mouse is moving to I think that should do it, but this is just a guess. Hope it gives you a good direction to start looking... Dave Re: Drag and Drop Text sanskypotov14-Mar-02 19:51 sanskypotov 14-Mar-02 19:51  Hi, Thanks, What I need is, how do I create, display ,move and resize Label Also I might need to display the Label in the CView, as I am not sure if I could drag and resize objects in CDialog. Any suggestions Regards, Sansky Internet Explorer "Save as" macro 14-Mar-02 2:11 14-Mar-02 2:11  Is there a way to use something like the Internet Explorer "Save as" method in my own programs? I want to save a webpage including the images... Is there a method / macro to use or do i have to do it all manually ( extracting the tags etc..)? Thanks for your help... Load a driver Don Miguel14-Mar-02 2:08 Don Miguel 14-Mar-02 2:08  Hello, My application need during execution to dinamically load a driver (.sys). How can I do this programatically? Also, how can I use Visual C++ to compile a driver? I search in MSDN and fount at visual c++ linker options "Use the /DRIVER linker option to build a Windows NT kernel mode driver. ". But how should I use this? I can't figure myself. Thanks Re: Load a driver Tomasz Sowinski14-Mar-02 2:16 Tomasz Sowinski 14-Mar-02 2:16  Don Miguel wrote: Also, how can I use Visual C++ to compile a driver? You'll need a DDK. DDK is the acronym for Driver Development Kit. http://www.microsoft.com/ddk/ has the details. AFAIR, DDK for Win2000 is even available as a free download. Tomasz Sowinski -- http://www.shooltz.com Re: Load a driver Tim Deveaux14-Mar-02 4:24 Tim Deveaux 14-Mar-02 4:24  You can set up a driver project in VC, though its a good idea to look at what build.exe does first. For the linker, the /subsystem:NATIVE,400 /driver settings will be needed. Compiler switches will vary based on language (c or c++). The NTDDK libs (int64.lib ntoskrnl.lib hal.lib) want _stdcall calling convention. On NT, you can dynamically load a driver using the service control manager, calling CreateService with SERVICE_KERNEL_DRIVER as the service type, then StartService. This doesn't work on Win9x though - not sure if its possible without user interaction (can u say PnP?). Re: Load a driver Don Miguel14-Mar-02 6:03 Don Miguel 14-Mar-02 6:03  Hello Tim, Thanks a lot for the tips with linker. Those are exactly what I need. Best regards, Miguel Re: Load a driver Lim Bio Liong14-Mar-02 4:31 Lim Bio Liong 14-Mar-02 4:31  Hello Don, To dynamically load a device driver in your (win32 USER-MODE) application, you would use the CreateFile() API. For example : hDriver = CreateFile ( "\\\\.\\Omron", GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, 0, // Default security OPEN_EXISTING, FILE_FLAG_OVERLAPPED, // Perform asynchronous I/O 0 ); Notice that the format of the first parameter. A device driver is named using the convention "\\.\<Device name>". You can get the list of names of devices when you look up the Control Panel's Services applet. After a successful call to the CreateFile() API, you will be returned a handle to the device driver (hDriver as in the above example). You communicate with the device driver via the DeviceIoControl() API. For example : bReturnCode = DeviceIoControl ( hDriver, IOCTL_OMRON_WRITE, &lWriteCode, sizeof(lWriteCode), &byReturnByte, sizeof(byReturnByte), &dwBytesReturned, &ov ); The second parameter specifies the control code for the operation that the device is supposed to perform. The technical manual (or SDK) for your device should supply your with these information. The other parameters are for transferring data to and from the device driver. Look up the API documentation for details. As for compiling a device driver, the traditional way is to install DDK as mentioned by Thomas in his mail. Hope the above helps, Don. Best Regards, Bio. Re: Load a driver Don Miguel14-Mar-02 6:15 Don Miguel 14-Mar-02 6:15  Hello Bio, Thanks a lot for your help, you bring many light in my project. Thanks also for pointing to me difference between USER-MODE and KERNEL-MODE, I was on a wrong way in my judgement about my task.

There are a bunch of those here on CodeProject. Take a look at this link: Visual C++ Macro's and Add-Ins and on that page there are a bunch. For instance, here's the URL for one of them: Auto-Incrementing Build Numbers in Visual C++. Hope that helps!

RichardWdy14-Mar-02 1:19 RichardWdy 14-Mar-02 1:19  I have a program derived form CMemDC. It can work perfectly in Win98, but it doesn't work in win2k. What's the problem and how to solve it? class CMemDC : public CDC { private: CBitmap m_bitmap; CBitmap* m_oldBitmap; CDC* m_pDC; CRect m_rect; public: CMemoryDC(CDC* pDC, CRect rcClip) : CDC(), m_oldBitmap(NULL), m_pDC(pDC) { CreateCompatibleDC(pDC); pDC->GetClipBox(&m_rect); IntersectRect(m_rect, rcClip, m_rect); m_bitmap.CreateCompatibleBitmap(pDC, m_rect.Width(), m_rect.Height()); m_oldBitmap = SelectObject(&m_bitmap); SetWindowOrg(m_rect.left, m_rect.top); } ~CMemoryDC() { m_pDC->BitBlt(m_rect.left, m_rect.top, m_rect.Width(), m_rect.Height(), this, m_rect.left, m_rect.top, SRCCOPY); SelectObject(m_oldBitmap); } CMemoryDC* operator->() { return this; } operator CMemoryDC*() { return this; } }; Usage: { CWnd * pWnd = GetDlgItem (IDC_MY_PANEL); CDC * pDC = pWnd->GetDC(); CMemDC MemDC(pDC, m_rcDest); MemDC.FillSolidRect(&m_rcDest, RGB(255, 255, 255)); MemDC.DrawText("Display here", rectDest, DT_SINGLELINE|DT_NOCLIP|DT_CENTER|DT_VCENTER); ...... pWnd->ReleaseDC(pDC); } Windows2000 SP2, VC++ 6.0 SP5 Re: Memory DC Win2k can't work! Tomasz Sowinski14-Mar-02 1:32 Tomasz Sowinski 14-Mar-02 1:32  This has nothing to do with your problem, but why are you implementing operator-> and operator CMemoryDC* ?
