• Visual C++ Running thread as a different user

  Hi, I am trying to an application which runs as Local System user. I want to spawn a thread which executes a particular function as a Run As user. Is it possible Thanks, Sushanth I don't really have a sample so I would have to look at those sites myself to find samples and such. Since this is outside the scope of this forum, it is better for you if you get help from a site in which people experienced with the subject are more likely to help. Someone might provide you a sample here but it is better for you to get a sample from a site in which SDK security is appropriate. For one thing, for this subject, a sample might not be enough; I think it is necessary to learn about security to be able to get something such as this to work. ...Show All

• Visual C# Streaming voice over UDP

  I want to transfer voice via sockets using UDP protocol. I capture voice with DirectSound to SecondaryBuffer. Because UdpClient doesn't have streams, I can't stream this buffer. what can I do How to send voice Just split up the data in SecondaryBuffer into chunks of byte[] suitable for sending with UdpClient.Send(). Put your buffer together again at the receiving end to play it back. You'll need to add a header to the byte[] so you can detect UDP datagrams getting dropped or getting received out of order. A simple block counter should do the trick. Test your code, and the effect it has on playback quality, by randomly dropping datagrams. ...Show All

• .NET Development Logging using Attributes

  I would like to log method execution in text file. I would like to use custom attribute to mark such method, but I don't know how to use custom attribute to run code before and after method execution Is that doable This is possible using reflection, although the end probably won't justify the means. At first glance it seems that it wouldn't be acceptable for any serious usage. An example of using a custom attribute to invoke a method can be found here: http://www.yoda.arachsys.com/csharp/benchmark.html . It also shows you how to perform pre- and post- processing when calling the method. Is the tracing provided by .Net not acceptable Enterprise Library also provides a tracing alternative. You might also try looking fo ...Show All

• Visual Basic read binary data stream from com port, write to file between certain characters

  I am new to using vb.net with binary and com ports and have a project where I need to monitor com5 for a binary data stream that I will receive every 5 minutes from a sensor. The data stream starts with "cs" and ends with "end" and I want to simply save the binary data that falls between these characters as a file with a ".000" extension. The "cs" and the "end" cannot be in the resulting file. I wasn't sure about removing "cs" and "end" since the data is in binary. Do I need to convert the entire binary stream to ascii and test for the "cs" and "end" then convert back to binary before saving Does anyone have a code snippet or suggestion on how I sh ...Show All

• Windows Forms Database Woes!!!!

  I am trying to enter data collected by an I/O card connected to the computer into a database. I have a data set and table adapters, no problems there. I can add the rows one at a time while the data is collected, to the dataset and when a specific number of new rows(in this case 25) has been reached the data set is appearently sent back to the database with a call to the Update() method in the table adapter. A text box displays the total number of affected rows i.e. 25. The problem is that when I view the table data in the database explorer my new rows are not in the database. As far as i can see I have all the neccessary code to save the rows and that they have been saved successfully but alas they are not there!! please help. Me . ...Show All

• Visual C# Refresh Property Grid Values

  Sorry, but I had to repost this in the C# forum because no one answered me in the Windows Forms forum. Say I have an object, "oFoo", and I assigned oFoo to a PropertyGrid on my form. oFoo also has a .CurrentValue property. If I have a TrackBar (tBar) on my form, and when the user scrolls the TrackBar, oFoo's .CurrentValue is updated respectively. How do I refresh the CurrentValue so that it shows up correctly in the PropertyGrid Right now, the only way I can do that is by refreshing the entire PropertyGrid, but I would think there would be a better, more standard way of doing this. I've tried using RefreshProperties(RefreshProperties.All), but it doesn't even refresh the value in the property grid, so I'm pretty stuck ...Show All

• Visual Basic Iterating through a panel's control collection

  Greetings: I've got a panel (pnlExpenses) with several labels and textboxes on it. I want the program to go through the dollar amounts entered in the textboxes and put the subtotal in a class level variable (dcSumOfExpenses). However, when the debugger passes through this Sub, objControl always shows a value of Nothing, and the Count of pnlExpenses.Controls always shows a zero. What is my code missing The panel was added to a tabpage at design time, and the labels and textboxes were laid on top of the panel. Do I need to do something more to establish the panel's controls as a collection Private Sub SumExpenses() dcSumOfExpenses = 0 Dim objControl As Control For Each objControl In pnlExpenses.Controls ...Show All
