• Visual Basic 1st time lucky, 2nd time's good, 3 times through and it crashes.

  I have a program that uses a subroutine that has an output file called temp.csv. It also has a sub that reads the output file using a streamreader, then closes the streamreader, I've watched it, and it always closes, even when I get an error. Every time through it deletes the temp file because in the output sub, it appends to the output file otherwise. When I run the program, and the program tries to delete the temp file, no problems, second time, no problems, third time, I get the another process is using this file... exception. Like I said, the streamreader is closed by this point every time, I've watched it. Any thoughts John Lieurance wrote: I've gotten burned by this one several times in t ...Show All

• Visual Studio Tools for Office You must have a complete installation of Microsoft Office 2007

  When ever I run vsto3ctp, I get this error shortly after install begins. I've install Windows XP SP2, then Office 2007, then Visual Studio 2005. After I got this message, I then reinstalled the entire Office 2007 suite again. I can't get past this step...very frustrating. Any ideas on what may be going on Cheers, Jay Hi Jay First, you have to make sure .NET Framework 2.0 is installed. You can get this by installing VS2005 (without VSTO) or just be installing the "distributable" Framework (available on the msdn site). This creates the GAC, which Office needs in order to install the PIAs. Now install Office 2007 (or use the "Change" type of setup via the Control Panel/Add ...Show All

• Visual Studio Express Editions Viewing variables

  Hello   While I'm debugging, even though the variables are fully defined, I can't seem to view them. They aren't recognized. What shall I do   Thanks There are several reasons for this, so you need to give more information. But if you have the program running in the debugger with the symbols in watch and you get the error CXX0017: Error: symbol "xxx" not found there are two things you should do. The first is make sure you got the spelling right, including case. You would be surprised on how many people get this wrong. The second thing to check is to make sure you are running the program in debug more without optimisations. The optimiser can remove variables it can do ...Show All

• Visual C# Exposing properties

  Hi! My idea is to include into language a mechanism to expose a field's properties. Let's say I'm inside some WinForms user controll. My control's got a label named label1. I want to expose the Text proprety of the label inside my user controll class and call it LabelText. The main pattern idea is to 'inherit' all the child's property attributes automaticly (like DefaultValue, Browsable and so on - these are just examples, Text proprety's got some others). I would only have to write single line of code that would do everything for me, like public LabelText = label1.Text; One problem I've noticed is that some of the attributes may be of private nested inside that class types, like class MyClass { [AttributeUsage(Attribut ...Show All

• Architecture Detecting internal calls in business object without using TLS or overloaded internal method

    Hi Forum I have the following problem. I need to know whether a call to a business object was made from another business object or directly from the UI. I need this because of Security and Logging reasons. Security - Users might not have permission to call the method on a business object. But another business object might need to call it. - But it's the same method :( Logging - I often want to log when a user performs an action. Another business object might also perform that action but then I don't what to log it. But it is the same method. ;( The best solution I have found is to make an internal version of the method with parameters. Like this: public class BusinessObject{ &n ...Show All

• SQL Server Slow Running Insert After Changing OLE DB Destination Data Access Mode

  Hello, In a Data Flow Task, I have an insert that occurs into a SQL Server 2000 table from a fixed width flat file. The SQL Server table that the data goes into is accessed through an OLE DB connection manager that uses the Native OLE DB\Microsoft OLE DB Provider for SQL Server. In the OLE DB Destination, I changed the access mode from Table or View - fast load to Table or View because I needed to implement OLE DB Destination Error Output. The Error output goes to a SQL Server 2000 table that uses the same connection manager. The OLE DB Destination Editor Error Output 'Error' option is configured to 'Redirect' the row. 'Set this value to selected cells' is set to 'Fail component'. Was changing the access mode the simple reason ...Show All

• Visual C++ Function name conflict with ENUM name

  Suppose I have a ENUM T_MuxPos_type, where T_MuxPos_type{fixed;flexible;}. While I am coding, I have T_MuxPos_type Mux_pos. When Mux_pos = fixed, I have no problem with gcc but a compilation error with mvs2005: c:\mvs2005\bs_module\source\config.cpp(1925) : error C2872: 'fixed' : ambiguous symbol could be 'c:\panliu_bs\mvs2005\bs_module\source\declareenum.hpp(43) : T_MuxPos_type_E fixed' or 'c:\program files\microsoft visual studio 8\vc\include\ios(183) : std::ios_base &std::fixed(std::ios_base &)' If I solved this problem by Mux_pos = T_MuxPos_type::fixed, gcc compiler will complain about it.

• Visual Studio 2008 (Pre-release) Window.DragMove() is swallowing all MouseUp events when created from ControlTemplate

  Hi all, hoping someone can help... I am creating a "stickyNote" kinda app; with multiple, borderless windows containing a TextBox and other relevant controls. I have defined a "StickyWindow" custom control, whose Content is defined by a ControlTemplate in generic.xaml. From another window, on Click I instantiate a new StickyWindow and .Show(). There are basically two controls a user can click on in a given SitckyWindow, the Border and TextBox. I want the user to be able to DragMove the window by clicking anywhere in the window. When the StickyWindow looses focus, I set the TexBox.Focusable to false, enabling MouseDown to pass through, and have wired up MouseLeftButtonDown and Up events to it. On MouseButtonLeftDown I cast the sender then ...Show All
