How to view (use) XIFF files? 2-Feb-01 6:39 2-Feb-01 6:39  Hi: I want to know is there any way to view (load into the program if possible) if not just is there any viewer for this type of files, so that I can call that application in my program in away or another. I'd appriciate any help. thank-you variable template parameter 2-Feb-01 2:59 2-Feb-01 2:59  Hello does anybody know if it is possible to use a vaiable datatyp in a template header. for instance template <class vartyp=""> ... the reason is that i would like to get the name of my varTyp from an external file. or does anybody has another solution? greetings WinLogon notification? Mathias Tunared2-Feb-01 1:54 Mathias Tunared 2-Feb-01 1:54  Hello! We have a service running under Win2k, and the problem is that we doesn’t know when a user has logged on and the Taskbar on the desktop is created. We need this information to create our System Tray afterwards, so that it will surely appear on the Taskbar. We have tried to solve this problem by implementing a Notification Packet DLL, which Winlogon.exe loads automatically and calls a registered logon function that was implemented in the DLL. This function will then inform MTS that a user has logged on. There is however, an uncertain span between the time when Winlogon calls this function, and when the taskbar is created on the desktop. We would like to ask which message or notification our service should subscribe, which will be sent to the service only after the taskbar is created? Thanks in advance!

Regardz Colin Davies How do they do anti-alias ??? Danoo1-Feb-01 20:21 Danoo 1-Feb-01 20:21  Hi I'm wondering since quite some time how do do a really good and fast anti-alias for a very common CView. When I look at Macromedia Flash or Freehand, it looks amazing but how do they do that? Anybody has some code snippets or such? Daniel Re: How do they do anti-alias ??? Chris Losinger2-Feb-01 4:23 Chris Losinger 2-Feb-01 4:23  anti-aliasing is simple in theory: your drawing algorithm tells you to draw a white (RGB(255,255,255)) pixel at (5.2, 10.4). but because you can't draw pixel at fractional locations, you have to distribute the "white" to the pixels closest to the ideal location. here's an easy way to do this: 1. pick the four pixels closest to your ideal pixel. if (5.2, 10.4) is your target, choose : (5, 10), (6, 10), (5, 11) , (6, 11) 2. for each of those, find the distance to the ideal pixel (use the simple 2D distance formula d^2 = deltaX^2 + deltaY^2. for the first pixel, the distance is sqrt(0.2^2 + 0.4^2). 3. based on the distance, blend a percentage of the "white" with the color of the current pixel. 4. repeat for every pixel you need to draw. yes, this will be incredibly slow if you do this with GetPixel and SetPixel. -c ATL Com progamming - needed help !!! 1-Feb-01 18:52 1-Feb-01 18:52  Hi I'm new to ATL Com programming. Recently I found a source code which I need to use, but on compilation there was error C2872: 'ATL' : ambiguous symbol. In the source it refer to the line :- if (ATL::InlineIsEqualGUID(*arr[i], riid)) Could anyone advise me what really is the problem? Thank for your time!!! Cheefarr Debugging VB COM Components from a C++ Client Chris Paulse1-Feb-01 16:49 Chris Paulse 1-Feb-01 16:49  I have a "hello world" situation with a VB COM DLL and an MFC client. When I switch the VB COM DLL to debug with "wait for component to be created", QI of LPUNKOWN for the default interface returns 0x80004002 (No such interface supported). If I don't run the COM dll in the debugger, everything is fine. If I use a compiled VB .exe as the client, VB component debugging is supported. I was told that this is a security related issue, so I went into dcomcnfg and added myself and the interactive user to "Access Permissions" and "Launch Permission" under the Default Security tab. No luck. Here is the relavent code in the client (hopefully I don't have to start learning about CoInitializeSecurity or get saddled with debugging VB in the VC++ IDE ) CoInitialize(0); IUnknown* lpUnk; // this succeeds each time, and hits on Class_Initialize in the debugger HRESULT hr = CoCreateInstance(__uuidof(WhyDebug::TheObject), NULL, CLSCTX_ALL, IID_IUnknown, (LPVOID *)&lpUnk); // this fails when the VB component is in "wait for component to be created" state // and succeeds with the VB debugger switched off. WhyDebug::_TheObject* pTheObject; hr = lpUnk->QueryInterface( __uuidof(WhyDebug::_TheObject), (void**)&pTheObject); Re: Debugging VB COM Components from a C++ Client Chris Paulse2-Feb-01 15:32 Chris Paulse 2-Feb-01 15:32  The problem here was I wasn't setting Project Compatibility to Binary. Hence, each time I ran the VB component, a new UUID was being generated for each interface. Duh! The old mouse recorder 1-Feb-01 12:53 1-Feb-01 12:53  Help.... How do you force mouse click messages in W95. MouseEventEx only works under NT is there another way ? I am creating a small very customized version of a the old W3.1 mouse recorder and this is the point at which I get stuck... Thanks in advance Re: The old mouse recorder Michael Dunn1-Feb-01 13:14 Michael Dunn 1-Feb-01 13:14  The mouse_event() function does what you want. --Mike-- http://home.inreach.com/mdunn/ Time is an illusion; lunchtime doubly so. Re: The old mouse recorder 1-Feb-01 14:07 1-Feb-01 14:07  Thanks.. Actually I did look in the help at mouse_event and saw "Windows NT" only then read no further - it refered to MouseEventEx only... Just goes to show you - read everything carefully... CRichEditCtrl and rotation AlexMarbus1-Feb-01 12:31 AlexMarbus 1-Feb-01 12:31  Hi, I'm currently writing an application: the user creates a (one or more) layout, and he/she can place one or more 'text-objects' on this layout. These text-objects are (at this moment) CRichEditCtrl's. I derived my own class from CRichEditCtrl, in which I do some neat stuff (like transparency etc). So far so good. A (very) nice feature to have in this application would be the ability to rotate these textobjects. Which means, in fact, I have to rotate the CRichEditCtrl itself, since CRichEditCtrl doesn't work with CFont/HFONT (Otherwise, I probably could do something with escapement). Does anyone knows a way to do this? There are probably some library's that'll do it for me, but I want to stick with CRichEditCtrl. (Unless you know a _very_ good library that does all other cool stuff like word-wrapping as well). Thanks for reading, I hope you can help me! -- Alex Marbus The following code looses memory.

MDI application kk91-Feb-01 9:18 kk9 1-Feb-01 9:18  Hi My application is a MDI application with multiple form views. I recently have this problem. When I click on Window/New Window menu, it pops up message such as "command failed". Does anyone know why? Thanks Sandra Building DLL's with mutual dependencies 1-Feb-01 7:57 1-Feb-01 7:57  We have a large project with DLL's that have mutual dependencies. (DLL#1 calls functions in DLL#2, while DLL#2 call functions in DLL#1). When we attempt to build the project we get errors because the each DLL requires the other DLL's lib file before it can link. The MS suggested workaround for this is to run the LIB utility on each project to generate lib files and then link everything together at the end. Unfortunately, VC++ does not appear to support this and to make it work we had to generate and modify make files. This is very error prone and we would prefer to do it some other way. Has anyone run into this problem before? Do you have a better solution? Thanks, Al (acarnali@speedline.com) MDI application kk91-Feb-01 6:35 kk9 1-Feb-01 6:35  Hi My application is a MDI application with multiple form views. I recently have this problem.

I'm intermediate programmer in Visual C++ and I've never write a VXD or SYS driver. Is there other way how to do it? function call within timer-callback .::RockNix::.1-Feb-01 1:08 .::RockNix::. 1-Feb-01 1:08  The MS docu says that no system-function should be called from within a multimedia-timer callback. I have the following command in my callback [...] system.pBitmap->Redraw_Map(); [...] pBitmap is a pointer to my own bitmap class and from within Redraw_Map() I have to call BitBlt(). Is this also a system-function call ??? And what is different by using PostMessage() and call my member-function from the event-handler ??? My code works fine ... what can happen after a system-function call from a callback ? Hope somebody makes this a little clearer to me Greatings Mario/// -------------------- www.klangwerker.de rocknix@lycos.de --------------------
