• Visual C# Reusing an open FileStream with multiple BinaryWriter objects

  Hi all, a quick question: Part of my application (Windows Forms / C# / .NET 2.0) deals with different objects which all have Serialize / Deserialize methods (custom ones, not implementations of ISerializable). At some point, I create a FileStream for writing, and then need to call those objects in turn, passing the FileStream object to the Serialze method. Each object should then append some binary data to that stream (and the reverse process for deserialization, of course). The problem: When first creating, say, a BinaryWriter, passing the FileStream, everything works fine, and the data is written. However, when the writer i ...Show All

• Visual Studio Express Editions Best way to do something

  I have a project and I'm not sure the right way to go about it - I'm after some ideas. Basically it'll be a program that takes ad bookings for a magazine and allows them to be placed on pages in magazine editions. I'm thinking of setting up a class for ads, pages and editions but my problem is that an edition will have properties like date, magazine, number of pages but also contain an array of pages then a page will have properties like number, colums and also contain an array of ads, then of course the ads themselves will be individual things but contain properties such as colours, requested page, advertiser, caption, etc. ...Show All

• Visual Studio Express Editions How to create an Icon image file

  Hi team, I have been trying to create an icon file for my new project. But I have been totally unsuccessful and I am confused. Since I have never done this before I must ask the question that is probably obvious to everyone else. What makes an Icon file an Icon I know that it has an extension of .ico but there is more to it than renaming a 32 x 32 pixel bmp to an .ico. Is it the size Some internal header data When I try and add a resource with the type "Icon", I select my image file but it gets imported into the "Images" area and not the one for Icons.

• Visual Studio Word Embeded in Crystal does not refresh! How to get it to REFRESH

• Visual C# C#.net 2005 to Excel 2003 - Insert function into Excel VBA Editor

  Hi guys,   The code below is a VBA function into Excel VBA Editor. The function opens an unknown file using 862 code page, save it as txt file, and reopens it using 28598 code page.

• Visual Studio 2008 (Pre-release) How to get scrollbar on ListView?

  I'm populating a ListView with several items (~100) -- more than can be shown on the screen. However, I never can get a vertical scrollbar to appear (I haven't tried for a horizontal one yet). I can select an item and hit the down arrow key and the selection goes off screen, so the selection logic appears to be working. How do I get the scroll bars to appear ListView is derived from ListBox and the vertical scroll bar appears when I use a ListBox and bind my data to it. Just for the heck of it, I put the ListView inside of a ScrollViewer, but that didn't work (I didn't expect it to). Vertical scrollBa ...Show All

• Visual Studio Team System Performance Issues with Version Control

  We (a dev team of about 15 people) have been experiencing some performance issues recently with Team Foundation Version Control.  It takes about 30 minutes to just load the project into Visual Studio and then another 30 mintues if you do a "Get Latest Recursive" on the entire solution. I setup SQL Profiling on the VSTEAMSCC DB and noticed some odd results: Based on the profiling duration, the sproc: prc_QueryItemsExtendedLocal is the main problem.  The Duration for running this sproc is anywhere from 10000000 - 1455555.  What is going on with this sproc I tried to open the sproc in SQL Server Management Studio, but it ap ...Show All

• Visual Studio Pointing at the .net 2.0 framework?

  Hello, I just upgraded to the 2.0 framework, and have tried within VB.net 2003 to point at the windows.systems.forms.dll that is in the 2.0 framework path (after removing reference to the 1.1 version). Studio responds with an error saying it's not a valid reference. I know I'm doing something wrong, there is probably a more top level setting to reference the new framework instead of the old. Any help Thanks in advance, Matt You cannot use VS2003 to develop for .NET 2.0. If you don't want to buy a new IDE, you can download VB.NET Express for free. ...Show All
