VS2005 RTM Team Suite On occasion while debugging the IDE becomes nonresponsive and I receive a Bubble message informing me that "Visual Studio is busy waiting for an internal operation to complete - If you receive this message often, please inform Micorosoft" After I receive this message the IDE never recovers.

• Visual Studio Problem with PDF Export CR10 / VS.NET 2003

  Greetings all, Im wondering if someone could shed some light on a problem im having with exporting to PDF. Im updating a report in an existing system - this report used to work fine until I installed VS 2005 on the system and now its stopped working.  The project is still being deployed from VS2003 and the IIS on the local machine is using ASP 1.1 What is happening is quite strange - if we try to use the ExportToStream() method to populate an iFrame it works fine and Adobe Reader populates the report in the browser - if we are just sending it to HttpContext.Current.Response then it stops working. This is the code we are using: ...Show All

• .NET Development Connection String problem with MSDAORA.1

  Hi. I have two connection strings for my application, one using Microsoft ODBC Driver for oracle, and another using Oracle ODBC Driver. I am getting "Object not found error( ASP)" when I use MSDAORA.1. I am using oracle 8i. Thanks. Sandeep Chanda wrote: Hi Paul, Its every line which has a CreateObject call. I'm sorry but that isn't enough information. What object are you trying to create Code would help. In any event, if this can't be resolved in the next response or so I think you're going to have to follow David's suggestion since this isn't really a .NET question. As much as I ...Show All

• Windows Forms Designer Fails to Show From after VS 2003 Port - Problem Fixed!!!!!

  Original Problem: After porting a project to VS 2005, the designer fails to show the forms in my project.  When I try to view the designer, I get Object reference not set to an instance of an object How do I fix this Is it possible that the resx files are corrupt  Can I regenerate them ------------------------------------------------------------ Solution The problem was solved.  It turns out that one of the project wide language resx files (we have four) had a slightly different format than the other project wide language resx files.  When we made the resx files consistent, the ...Show All

• Windows Forms Considering a bugreport about AutoScrollPosition property of the ScrollableControl class

  I used the ScrollableControl class in one of my projects for a while and I'm puzzled why the class implementer from MS decided to implement the AutoScrollPosition property in such an inconvenient and weird way. Here's from the WinForms 2.0 docs: AutoScrollPosition represents the location of the scrollable control's display rectangle. The X and Y coordinate values retrieved are negative if the control has scrolled away from its starting position (0,0). When you set this property, you must always assign positive X and Y values to set the scroll position relative to the starting position. For example, if you have a horizontal scroll bar and ...Show All

• Visual Studio Express Editions Confused about method returns and params

  Howdy folks, Newbie comin' through... I'm confused about when a method is returning a value. I'm also confused about when a method is taking in a parameter or passing out a parameter. I understand that when a method name is preceeded by the "void" key word, it is not returning anything. However, when a method is preceeded by the keywords "string", "int", etc. it is returning a value of that type. my questions are these: 1. When a method is returning a value, is it necessarily doing this by passing a parameter out of itself 2. when a void method contains parameters, how does one know if those p ...Show All

• Windows Forms Creating Custom Textbox Control .NET 2005

  Hello, I want to create a custom textbox control. I want this control to have fewer properties than the textbox control that is provided by .NET Can i do so. Please suggest. Regards, you can add a custom designer class, and override the PostFilterProperties method, and remove any properties you dont want displayed in the designer. you can also add new private properties that hide the original ones. another more involved way is to create a class that inherits from Control and either have an internal textbox variable and wrap it in your class (provide properties that you want displayed), or set your CreatePar ...Show All

• .NET Development No connection could be made because the target machine actively refused it

  Trying to connect to a local host TCP port 3380 (the port number chosen arbitrarily): 10.1.10.176:3380 I got this error message: No connection could be made because the target machine actively refused it What shall I do to convince the target machine not to refuse it the next time I used a sock.Connect(serverEndPoint); statement. Thanks This means that there is no TCP Port *LISTENING* for requests at the port 3380 you mentioned. It could also mean that there is a firewall of some sorts that is not allowing incoming connections on that port eventhough you might have a server listening on that port ...Show All
