• .NET Development Using a ReadTimeout at SerialPort component

  I have a question. I am using the SerialPort object in a project I am working on , and I am having a problem with a timeout catching. As known, in Serial port object we may use DataReceived, PinChanged and ErrorReceived events/delegates. Thats all. What is a right way to catch timeout event Thanks. A timeout is signalled with a TimeoutException. These are thrown only when you call a "blocking" method like ReadByte, ReadLine, etc. If you implement DataReceived to read data from the port, you won't need nor use a timeout value. ...Show All

• Visual Basic DataGridView edit causes Form.Show() to crash

  Hi all, I have an MDI called "Question Centre" with a docked ToolStrip that controls the navigation between the sub-forms within it. One of these forms has an editable DataGridView on it. I experience an "Out of Memory Exception" if I am currently in "Edit Mode" of the DataGridView when I click the ToolStrip to swap to another form. The exception is explicitly throw on the form.Show() event in the ToolStrip's OnClick event. This exception does not occur if an uneditable cell is selected. It also does not occur when I jump between editable cells without changing forms. It only ever occurs when I am ed ...Show All

• .NET Development request.BeginGetRequestStream with FTP in ACTIVE mode problem.

  Hi, i'm making an asynchronous upload function. When using .usepassive = true all is good, i can transfer and catch pretty much every exception thrown at it. When using .usepassive = false and the server and client are both configured properly, all is good too. The problem i have is when .usepassive = false and either the ftp or client are not configured properly to use active ftp connections. Here is the code that calls the BeginGetRequestStream request.BeginGetRequestStream(New AsyncCallback(AddressOf EndGetStreamCallback), state) waitObject.WaitOne() After BeginGetRequestStream is used and EndGetStreamCa ...Show All

• Visual Studio Team System Perfmon and VSTS

  Hi, I am using the TeamSuite edition to record the performance metrics using loadtest containing recorded webtests. The reading that I see on the perfmon of the server and the readings in the VSTS always are different, particularly for the counters % time in .Net CLR Jit and % time spent in Garbage Collection on the server. I am collecting readings every 10 sec at both locations, usually(almost always) the metric on VSTS is approx. twice the number that it shows on perfmon. I am trying to use perfmon more effectively by changing the x-axis if possible for more precise readings and also export the performance logs into an excel spre ...Show All

• Visual Studio Error "Operation is not valid due to the current state of the object"

  I'm trying to use the ReportViewer control (in remote mode) in a winform app. Everything works great until I try and change the ReportPath of the control (in response to a TreevIew after select event ) when the currently visible report is a report that has been drilled into from the original report specified in ReportPath e.g. ReportViewer rv = new ReportViewer(); /* other code */ rv.ServerReport.ReportPath = "/Report1"; rv.RefreshReport(); User then clicks on a link in Report 1 that jumps to Report 2 (still within the same control). Now if you try and set the ReportPath to anything you get an "Operation is not valid ...Show All

• .NET Development Problem with Asserted Permissions

  I have code that is hosted in IEEXEC. The same code can be run from a local or remote file and it will work. When it runs from IEEXEC it fails because of code access permissions. (The code is trying to use remoting to connect to a host that is other then the one it is loaded from.) The assemblies are strongly named and fully trusted. I found an article that indicates the following line of code will allow code in a fully trusted assembly to do anything that it wants regradless of the AppDomain or previous deny settings.
