• Visual C# A newbie question on Interfaces

  hi,    I'm new to C# and OO in general. I can't seem to undestand the pertinence of interfaces.   From my understanding, the interfaces define the signature of the methods while the class implements these methods. How is this better than simply doing away with interfaces and simply implementing the method in the class   Apologies for the rather novice question, an example to illustrate the pertinence of interfaces would be greatly appreciated. regards, Pat Arrays are kind of funky for some reason. I know the docs say that it implements the IList interface, but in playing around with it, the only way I can see ...Show All

• Visual Studio Express Editions Using VB.NET Compiler as an older version

  Is there a way to make the VB 2005 Beta 2 Program compile to an older version e.g. VB6 The MSBuild Compatability Toolkit allows you to replace the "standard" MSBuild files (which tell Visual Studio how to build you application) with versions that can target .NET 1.0 or 1.1. The scenario where this would be useful is if you are using Visual Studio 2005 to develop your application, but you want to build applications which run on .NET 1.0 or 1.1.  The instructions at the end of the setup describe in depth how to use it.  Note that this will not make an exisiting .exe run on a different framework, it w ...Show All

• SQL Server Updating database with file feeds from Internet and then parsing the XML, CSV or Excel data for insert/update/delete in Yukon

  Hi, I'm developing an ASP.NET web application with SQL Server 2005 standard edition on the backend. I am looking for a solution to the following problem: Need to have SQL Server 2005 do the following at 3am each morning: 1) Download updated pricelists from URLs stored in the database 2) The pricelists vary in format - some in XML which is ideal, others in CSV which is not bad, a few are in simple excel .xls format which is not so good and some others are formatted with eye-candy for human reading which is terrible. For the moment I am only looking to read in the first three as XML and enter the data into my database. As you can imagine, the ...Show All

• Visual Studio Team System Check-in policy results in high use of shelving

  Check-in policies are a great idea. The result is that we need to find an alternative method for backup up developer's work, since they will no longer be able to check-in periodically throughout a day. Shelving appears to be the best option. However, shelving requires creating a shelveset name, and results in multiple versions of files if done daily or even more frequently. Shelved projects can be deleted and a naming convention developed, but the entire process seems potentially unruly. Any recommendations, work around, or thoughts on how to best manage this process with a team Thanks in advance. Mark ...Show All

• SQL Server Datatype problem?

  Hello We ahve a problem with datatypes. I the cube whe have 2 mesasures (Item_Sold and Sales). Item_sold is Numeric datatype and Sales is Currency. In the virtual cube whe divide the to in to a average price (Sales/Item_sold). We user Excel show the cube. For integer numbers we get no problem but for item_sold with decimal values (like 1,43) the division get currupt. It seems that it only devide the integer so  average measures of: Item_sold=2,5 Sales=500 ...will be 250 (500/2). And if the item_sold is smaller than 1 (for units smaller than 1 kilo) the average value will even more strange. I think that the datatyp is the error. What dat ...Show All

• Visual Studio Express Editions BindingSource.Filter Problem Part 2

  Sorry for reposting this, but my new question was burried within the thread of my previous post and I wanted people to get a fresh look at my problem. I have a form with a DataGridView with multiple columns. I have another form that pops up to give the user options of filtering the data in the DataGridView form. I have several ComboBoxes bound to tables that contain the data available in a certain column in which the user can select items from the ComboBox to filter the column. Thanks to tabdalla, I was able to get the code to make a single column filter based on the item selected in one of the ComboBoxes. Here is the code tabdalla he ...Show All

What I did was to set the image's background color to gold, which worked fine in the development environment. However, after deploying my app to the device, I found that my image's background color was BLACK! Why is this so and how can I change the image's background color I also tried setting the image's background to transparent then changing the form's background to gold, but I got the same results.(it worked in the IDE but not in the device) Finally, I created new square images (the circle placed in gold background) and place ...Show All

  I'm trying to create a program that has a + button on one side and a - button on the other... and a "label" in the middle which will show .5 increments either up or down if I click one button or the other (.5, 1, 1.5 or -.5, -1.0, -1.5 etc).
