• Visual Studio 2008 (Pre-release) emulating a mouse in WPF

  Hi, I am trying to emulate a real mousedevice and its behaviour (left click,right click, mouse enter, mouse leave etc) by creating a custom control for it. So far I have not been able to figure out how to implement this. If any one has any experience in this please advice, how I could go about creating this or maybe an altogether different idea for achieving the same would be really appreciated. Thanks You may want to have a look at Win32 function SetWindowsHookEx. I tried it in the past and it worked quite well. - Abhijit ...Show All

• Visual Studio Team System Branching Strategy For Dynamic Environment

  I am working in a very dynamic environment where several different features and bug fixes are worked on simultaneously by many different developers. The project is a large public facing website that must have bugs resolved quickly and has constantly revolving promotions. We are having a problem deploying changes quickly when some technical features may take weeks to develop while other minor ad campaigns may take only days to develop. So I was thinking that an environment like this would benefit from each developer having a private branch. and then merging in chages to the main branch when a feature was complete. I set up a prototype of this environment and private branches seem very clunky in Team Foundation Server. I have seen many peopl ...Show All

• Software Development for Windows Vista Is there a problem with the DelayActivity with Sequential workflows?

  If I enable my DelayActivity at the bottom of a SequenceActivity inside a WhileActivity, It doesn't continue back to the top of the loop. If I disable the DelayActivity it works, but of course doesn't wait between Activities. I have a timespan set to 00:00:01... I've tried 00:00:05, and 00:01:00 i.e. SequentialWorkflow structure looks like this...

• Audio and Video Development Sliding menu animation error

  The sliding menu I did in Markup, with Peter's help, is working pretty well. It slides open on start, and closes automatically if a track is selected. However one thing I cannot fix is that after the first time you open the menu while a video is playing, it will no longer animate, it just appears. For example: 1) Start project, after 1s menu slides open. 2) Select track, menu automatically slides shut. 3) Open menu using menu button (CTRL+M) and menu slides open. 4) Select another track and menu slides shut. 5) Open menu using menu button (CTRL+M) and menu DOES NOT slide open, but rather just appears. This will happen everytime you open the menu after step #4 in this example. Any advice on how to debug <timing clock="page" ...Show All

• .NET Development Control of system clock

  Hi, Intro: I have a network sniffer connected to a UDP network. I use WinPcap with my data extraction API located on an interface PC. GUI is made in Visual Studio. I have full control of the time recorded on the sniffer (from extracting time in telegram header) but I run into the following problem: When I try to play back the UDP stream via 100MB onto a server running Win XP, the receiving application receives it's time from the system clock. I am not interested in showing the current time when the playback is not in real time. I am interested in showing the time from the extracted data. When I play back events and alarms all time stamping gets wrong since the UDP playback stream does not contain time stamp in use by my application. ...Show All

• Windows Forms Datagridview, bindingsource, thread problem

  I have a datagridview with a bindingsource as a datasource. the datasource of the bindingsource is a datatable from a dataset. When a change occurs in the datatable .. i get notify ... when i get notify i applied the changes in my cache version of the datatable where the bindingsource is pointing. i get the following exception : System.IndexOutOfRangeExceptions: Index 0 does not have a value at System.Windows.Forms.CurrencyManager.get_Item(Int32 index) at System.Windows.Forms.DataGridView.DataGridViewDataConnection.GetError(Int32 rowIndex) I think it's due to a thread problem .. since the datatable is only thread safe on read-only and not write.

• Windows Search Technologies WDS 3.0 Beta 2 Crash srchadmin.dll

  Hi! Every time I try to go into the filetypes in the Advanced option dialog WDS crashes on me. I get up a box saying "RUNDLL An exception occurred while trying to run "shell32.dll,Control_RunDLL "srchadmin.dll"". I used to have WDS 2.5 with some extra IFilters but I removed all that before I installed the beta. Thanks. Matt I think I found a possible explanation to this.

• Gadgets Missing thumbnails on gallery.live.com

  I seem to notice a lot of Gadgets on the galley.live.com page don't get their thumbnail image displayed (mine doesn't seem to show up about 80% of the time). Anyone have any insight into this issue I've noticed it ever since I uploaded my gadget (about a month ago) and it still persists today. It rarely displays the thumbnail and it seems to be sporadic as to when it will actually show up. I notice there seems to be a few others whose images do not display either. ...Show All
