• mobigital Autoplay - Multiple Event Prompts

  We are implementing autoplay for a non-volume device according to MSDN article "Autoplay in Windows XP: Automatically Detect and React to New Devices on a System". We are on XP SP2. In short, the problem is this: When we plug our device into the USB port there are two event prompt windows. One of the event prompt windows is what we expect - it displays things as we have them set up. But there is another event icon in the notification area of the taskbar - when we click on it an empty event prompt window appears. Has anyone experienced this problem Why is that second event prompt happening We have tried many things. We tried specifying a different handler (VideoCameraDeviceHandler). We tried responding to an event from a ...Show All

• Mike Batton another date related problem

  I wrote a program that asks for a year and a day number between 1 and 366. It returns the date for that year and day number in the format:  "Weekday, nnth Month year" where Weekday is the name of the weekday nnth is the day of the date (with the appropriate suffix: st, nd, rd, or th) Month is the name of the month and year is the year. I wrote this program incorporating the System namespace and using the Console functions. I used the DateTime object to get the current date and set variables for the current year, current dayOfYear and current dayOfWeek. The program is working correctly. I also wrote code using the std namespace. To get the date I used ctime. The following is the code I used: time_t mytime; s ...Show All

• crp2k4 Listen - WinSock

  Hi! I am just trying out few options with Sockets... I was reading the MSDN for the listen function and found the following lines.... If there are no available socket descriptors, listen attempts to continue to function. If descriptors become available, a later call to listen or accept will refill the queue to the current or most recent backlog, if possible, and resume listening for incoming connections. If listen is called on an already listening socket, it will return success without changing the backlog. Setting the backlog to 0 in a subsequent call to listen on a listening socket is not considered a proper reset, especially if there are connections on the socket. Can anyone elaborate on the same lines Does it implie ...Show All

• m14cus 64b development: Huge problem with VS2005 on a 32b OS

  Hi, I've just discovered this weird bug in VS2005: when compiling and linking my application with the x64 platform target on a computer running Windows 2000, the executable can't be run on a Win64 computer. I've spent a lot of time trying to solve this pronlem, and I found the following: - by using Depends, I found that it's the "exported symbols" table that's invalid in these files, - it seems to be related to the Embed manifest option, because disabling it will generate valid executables and dlls, - the problem doesn't happen if I link the file on a Win 64 computer. So it seems that the Embedding process is not correctly done for 64 bit executables on 32 bit computers. By searching for this problem on the internet, I found that - some us ...Show All

• Chris.Stewart Creating a text box in a dialog and processing it using the message loop

  How do make a text box in a dialog I need it so that i can set a text box to a string, and as the user edits the numbers of this box, any other numbers of the same type become that value, e.g. 12234356 If i change either 2 to a Q then it would instantly become: 1QQ34356 How do i initially make a text box in a dialog And how am i going to pass a text changed message to the message loop within a dialog After this i can simply compare it to the original string and change the other values, that bit isn't too hard.

• KrazyMGA how to solve LNK2001 and LNK1120 problem

LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main Debug/try1.exe : fatal error LNK1120: 1 unresolved externals Error executing link.exe. Well, you need a main function because this what the system will call when your program is executed. You need to add this function and then call the code you already wrote from this function. Are you making a console-, or windowed / background application If this is a console app, you will need the "int main", as previously mentioned. If you've already got a WinMai ...Show All

• Alek Davis CTabCtrl drawing problem with XP Style

  VC++ 2005 MFC. I'm using a CTabCtrl. The control works just fine if I do not include a manifest for XP Style. If I include a manifest for XP Style, the CTabCtrl stops drawing on most of it's client area. By stop drawing on most of the client area, I mean it draws about 4 pixels from the top and left correctly and everything else is not drawn. The controls on top of the CTabCtrl are drawn properly, it's the background and bottom/right borders that do not draw. By not drawing I mean it just keeps whatever was on the screen there before. If I drag a window across it, I see the remanents of the dragged window. It's like the CTabCtrl just decided to clip out everthing below & right of (4,4) of it's client area.

• ronks How to deploy MFCMIFC80.DLL?

  Hello VC++ Forum, I've added a CWinFormView to my MFC MDI project to show a .NET 2.0 control. Really really nice and working fine :) Now I wanted to test my stuff also on another machine and copied my DLLs and EXE there. That machine got .NET 2.0 and MFC 8.0 components installed. Well, when I want to open my View now, I get a message "MFCMIFC80.DLL version 1.0.0.0" missing. After that message, the program gets teared down and I must use the taskmanager to shut down its process. I tried to copy that DLL to the machine, but that doesn't help. I tried to install it to gac, but that won't work. Now I'm curious what I've got to do. I asked our deployment guy, and he said the MFC runtime stuff is installed on that machine. He doesn't h ...Show All
