• .NET Development SslStream.Read() - Returns invalid data

  Hey, I am currently attempting to implement a multi-threaded C# socket, using SSL (.pem file/certification/private key combo) server using Visual Studio C# Express. I have successfully made the client application establish a connection, and send data, which appears in plain, de-crypted text on the server - this works. However, I am 'polling' the socket to see if data is available to read. Here is some code which is appropriate: ---- public void Process(int threadId) { int BytesRead = 0; try { Master.Log("BEGIN READ"); sslStream.ReadTimeout = 5000; BytesRead = sslStream.Read(bytes, 0, bytes.Length); Master.Log("READ " + BytesRead + " bytes"); if ( BytesRea ...Show All

• Visual Studio Cannot change the reports of ReportViewer control

  I am using a tree to select various reports to be displayed into the ReportViewer control on a winform app. However, only the first report is displayed and the control does not reload any other reports. Using the following code does not change the report being displayed: this .reportViewer1.LocalReport.ReportPath = "selected report path" ; this .reportViewer1.RefreshReport(); Is this a limitation of the control Is the only solution to re-create a ReportViewer control for each report to be displayed Thanks.

• Visual C++ default destructor and list iterator

  I came across a problem with a default destructor. The problem has been distilled down in the code at the end. I have an Iterator class that is used to access std::list<>'s. The original design was that a pure abstract base class was used to provide an interface. But if I define a pure abstract base class, bad things happen. From what I can see, the default destructor does the wrong thing and delete's the pointer to the std::list<> used by the subclass. Here is where it gets truely odd: only if the std::list<>::iterator in the object is initialized, does the destructor do something bad. Simply creating and deleting the object does not create a problem. If I implement destructors that do nothing, all is well. But my dest ...Show All

• Visual Studio Visual Basic Debugger Crash

  I have just recently installed Visual Studio 2005 and in my GUI Design class we have opted to use Visual Basic. The problem I am having is that whenever I try to use the debugger by setting a breakpoint, everything goes well until I actually reach the breakpoint. When my program reaches the breakpoint, everything freezes up. I am unable to force quit the program or Visual Studio, or alt-tab to any other applications. The only thing I am ever able to do is bring up the task manager with ctrl-alt-del, but I am unable to kill processes or anything from the window, as it too freezes when I click on the window with the mouse. This is on a fresh install of Visual Studio 2005 on a fresh install of Windows XP Professional SP2. I have all the updat ...Show All

• Visual Studio 2008 (Pre-release) WCF services from existing wsdl

  I want to generate a wcf service from an exiting (non .NET generated) wsdl file. I created the service code using the .Net 3.0 SDK svcutil and discovered that the wcf service wsdl is completely different from the original wsdl used to generate the .net service types. How do you ensure that the .Net service metadata mirrors the original wsdl as I have .Net clients generating their proxies from that original wsdl and compatibility becomes an issue. The .Net wsdl is creating new wsdl messages and parts it just doesn't jive with the original wsdl. Some insight into how to work with 3rd party wsdls to build a .Net service is appreciated. Chris Thanks for the suggestions. I went back and ran the svccu ...Show All

• Windows Forms Adding data to child tables using FormView and Object DataSource

  I have a FormView that displays all data in its item template view and another formview that displays related data. I am filtering the child data using the SelectedValue of the Parent FormView. The problem is when I want to add records; Adding data to the parent work just fine. but when I want to add records to the child table I don’t want the user to enter the id of the parent record, since the parent data is already displayed above it is understood that the user add child records to that parent record.. Unlike the read-only view I am not able to get the SelectedValue of the parent View. Is there any means to get the parent id... If the above problem is not clear, let me take an example: I am displaying details of an event ...Show All

• Visual Studio Can't Find Crystal Reports

  Hello, we have Visual Studio Team Edition installed on a machine. We're trying to use Crystal reports, but we can't find it. I checked the installation, and it claims to be installed. It doesn't appear in the new file list anywhere. Thank you for your help! Hm. Visual Studio Team System appears to be a collection of about seven different versions of Visual Studio (See the products page for more details ).

• Visual Studio 2008 (Pre-release) proper way to use BuildWindowCore params?

  In the following code, I'm attempting to make my own .NET 2.0 form act as a FrameworkElement. I'm having trouble in the BuildWindowCore function. As I understand it, I'm supposed to take my existing form and make it a child of the input HWND. I don't know how to take the hwndParent.Handle and turn that into a System.Windows.Forms. Control. I've stepped through the code a number of times trying different things includeing WINAPI SetParent all with no luck. It's too bad Wrapper is null. That would at least give me an idea as to what type of object it is. public class AppWindow : HwndHost { private AppForm _appForm; // AppForm inherits from System.Windows.Forms.Form public AppWindow( AppForm appForm) ...Show All

• Windows Forms PrintPageEventArgs Supplies a Graphics Object with Random VisibleClipBounds

  I am facing a problem where only a portion of the page I am trying to print shows up on the printer. I see that the same problem is reported by a number of people: a. http://www.thescripts.com/forum/thread225516.html b. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=38324&SiteID=1 c. http://www.dotnet247.com/247reference/msgs/24/121201.aspx After spending some time, I find that the Graphics object supplied by PrintPageEventArgs in the PrintPage event is giving a "random" VisibleClipBounds.
