• Visual C# USB Communication

  Is there a way to control Voltage output of a USB Port. I'm trying to connect a custom made circuit through USB and send power on request to it. (Connecting a USB device automatically yield power to it or do you have to open the port first ) So I am to understand the Voltage out cannot be cut using software I was looking at creating a switch from a transistor which will trigger the circuit to receive Supply (12+V) power from the outlet when the USB provides 0.7V or more power to the transistor) - Needed to control the switch via software somehow but if it's not possible I might have to use a Serial or LPT Port instead :( Thank you for the replies. ...Show All

• Visual Basic Why does my app try to connect to the internet?

  This was really strange. After finishing my application (first one in vb.net) I ran it and for some strange reason it tried to open a port (1147) and according to my firewall it was listening not sending. I found this very strange because my application doesn't contain any code what so ever that would be able connect to the internet. I even tried a simpler application with just a form and a button and that one also tried to open up a port. When i blocked the program from trying to listen, it crashed giving me this error report.

• Smart Device Development Programmatically change wallpaper on a Windows Mobile 5.0 Device

  Hi everyone, I am trying to write an app to programmatically change the wallpaper on a Mobile 5.0 smartphone. I have looked at the Compact Framework and cannot find a way to do it. I have also looked at CoreDLL.dll and could not find anything. I am doing development with VS.net 2005 and .net Compact Framework. I know we can use SystemParametersInfo from User32.dll for a windows PC but can't find anything for a mobile device. Any help will be appreciated. Thanks. This forum is intended to deal with issues directly related to the .NET Compact Framework. It appears that this question can better be answered by someone on one of the newsgroups for Windows Mobile or Windows ...Show All

• Visual Studio Team System Determine if there is a label already applied to the latest version

  Is there an easy way to determine if there is already a label applied to the latest version Can you explain how this info would help you To me, it's not really meaningful to ask if there's a label applied to "the latest version" because labels don't represent points in time. Let's say you cut a label 2 years ago. Since then, some files have been modified extensively and others haven't been touched at all. That is, it applies to the latest version of some files but horrendously out-of-date versions of other files. Would you want that label to be returned by your query That's just the tip of the iceberg. What about a label that contains {aaaa.txt @ C1, aaab.txt @ C2, aaac.txt @ C3, ..., zzzz.txt @ C456976}. Should we show ...Show All

• Software Development for Windows Vista Shower on 64 bits than 32 bits because of kernel ?

  Hello, I am working on a program that have been ported on Win64. Unfortunaly the program is really slower compiled with the 64 bits compiler on WinXP 64 than compiled with the 32 bits compiler on WinXP 32. It seams that the kernel use much more ressources ... even if system functions aren't called and there isn't memory allocation (or a few number) during tested periode. The following screenshot show what's happening: http://img110.imageshack.us/img110/8867/64vs32vi4.jpg Do you know from where this kernel ressources are required The application used the Win32 API with MFC (few) and OpenGL. But during this test, these library aren't really involved... Thanks ...Show All

• Visual Studio Express Editions VB.net2003 or Vb.net2005

  Hi, A final project has been assigned to me in which I've to make an online application for the courier systems, it should have a reporting system and show the entries contained in the DB, there is a requirement to make it in .Net2003 but I've recently heared about Vb.net2005 or VBE which is the latest .net version of VB and also has an IDE by which an interface can be made easily. Here I should mention, I've never worked in .net but I used VB6 so I don't know about VB.net yet, and the time is very short I've to make the interface within a month or so.Please tell me, whether it is good to use VB2005 express edition and learn vb.net code simulateneously or should I jump into vb.net programming and forget about VBE.I prefer VBE cuz it ...Show All

• SQL Server A priori algorithm in Association Rules

  MS uses the a priori algorithm in Association Rules, while other DM software have gone to the Novel Algorithm. Can you tell us why MS decided to stay with the a priori Did you overcome the limitations that it's accused of having Thanks! I was only able to find one reference to a product that claimed it used "the" novel AR algorithm, without much more description. I found many AR algorithms with novel approaches to solving various problems. Do you have a reference to a paper Our apriori implementation does a lot of different things to work around the limitations of apriori. For example, we do things like allow less frequent frequent itemsets to be flushed to disk during our counting, or automatically change the thresholds ...Show All
