• Visual Basic Temp Image file is locked and cannot delete

  Hello, I just can't seem to get this to work right for some reason. I am getting pretty frustrated and I am sure it is an easy fix. I have the following line of code: Dim pictForm As Image = Image.FromFile(strFilenameJPG) In the next couple of lines, I draw the image into my graphics object. The strFilenameJPG varaible is just a temp file. When I have completed my grahpics work, I want to delete the file. I use the following line: Kill (strFilenameJPG) However, I get an I/O error every time saying that the file is in use. I have tried several methods such as disposing the pictForm object and setting it equal to nothing, but I always get the same error. Any help would be appreciated. Tom Thanks again for t ...Show All

• Visual C# Using numeric literal suffix 'M' on a constant value passed to an attribute

  Hi, I was surprised to find that I could not use the literal suffix for decimal: "M" or "m" to explicitly represent a decimal literal value as a constructor argument to an attribute. I require this because I need to perform a cast and comparison at runtime using the literal boxed value that was passed to the attribute, and if the boxed value is not of the expected type then an InvalidCastException is thrown. Therefore the literal constant value must be of a specific type, which is normally achieved via the suffix approach. For example, given the following attribute declaration: [ AttributeUsage ( AttributeTargets .All)] public class MyAttribute : Attribute { public MyAttribute( object someval) { ... ...Show All

• Visual Studio 2008 (Pre-release) What is the best way to use DataContext in ASP.NET app?

  Hello! I have an ASP.NET app. where I use DLINQ. I want to find out the best way of using DataContext because perfomance is a critical thing. I have these variants: 1) DataContext will be initialized only once and placed into the Session. (But my DB structure is quite big) 2) DataContext will be initialized every time when a query executes. 3)... Please tell me your suggestions. Well, just because you have a lot of tables doesn't mean that your app needs to concern itself with all the tables, all the time. If you drop the metadata requirements, you might be able to shave a little be a performance if you restrict your view of the database. Honestly, I'm suspecting this isn't as much a concer ...Show All

• SQL Server I forgot my SA password for my instance of SQL 2000

  Hi all, I have SQL 2000 and I forgot my SA password and cannot login as administrator using windows authentication. Is there any way to reset SA password "Mixed Mode" authentication is enabled. If I change authentication mode in register to Windows only and then after restarting SQL change it back to Mixed, will it reset SA password to "null" Thanks in advance. Just in addition to Glenns post and your qustion: It won’t reset the password to null with changing the authentication type back and forth. If you don’t have any GUI to administer your passwords you can use the procedure sp_password passing in a NULL for the old password parameter, as you don’t need the old if ...Show All

• Internet Explorer Development Horizontal browser window under main page.

  I am developing an application inVS2005 that requires me to open a web page that has 3-4 lines of text in a seperate browser page underneath the normal window in ie6 or ie7.

• Game Technologies: DirectX, XNA, XACT, etc. XNA Games OUT OF THE BOX??

  I cant make them work on a PC with just .NET 2.0 DirectX and the XNA Framework, it still needs the GSE and VC# Express, otherwise I get an error that the framework dll should have been installed into the Global Assembly Cache. Make sure (i.e. run the app) you have all of DX9.0c including the optional components by running the web installer. The SDK does not install everything (I think its jsut the latest versions and XNA relies on the October components) and the OS does not come with ANY optional components. http://www.microsoft.com/downloads/details.aspx familyid=2DA43D38-DB71-4C1B-BC6A-9B6652CD92A3 I've lost count of the nubmer of people on the forums who assure us they have DirectX 9 but this in ...Show All

• Visual Basic Windows Form Display Problem in Visio

  I apologize if this is the wrong forum for this question. I have a COM interop program which loads into MS Visio 2003 and displays a menu command bar upon seeing the correct drawing template. One of the menu options displays a Windows Form (modal). The problem is the display and graphics quality. There are four groupboxes which contain text boxes for user input. Not only is the font slightly different (almost like a red trace around each character), but the groupbox outline does not appear. The items in the groupbox appear, but the title and box outline do not. I designed the form in Visual Basic 2005 and refer to it in my code as ------------------------------------ Dim form As New form form.showdialog() ------------------------ ...Show All
