• Visual Basic Combobox question

  hello. A question please. If I add elements to a combobox manually, I mean for example combobox.Items.Add( "Monday" ) Can I associate a key to each element of my combox Something like this: ComboBox1.DataSource = datatable ComboBox1.DisplayMember = "long_name" ComboBox1.ValueMember = "id" Thanks in advance...   I arrive with another question on the same thing, I guess.

  Hi. I have a money field and its value is greater than a thousand.For example its value = 32.885,60 I want to show the field's format like this (this number's format). I mean the thousand separator should be .(dot) and the decimal separator should be ,(comma) And I want two digit after the decimal separator.All these conditions matches with this number(32.885,60) Could you help me You can accomplish this by adjusting the Language property for the textbox, or the entire report to a language that uses this format.

• Visual Studio 2008 (Pre-release) Domain Driven Design

  I was wondering if ADO Orcas was influenced by the concept/book Domain-Driven Design. Developing with a truely rich domain model is a fairly new concept to me and I am in the middle of reading the book. I wonder if anyone developing with ADO Orcas can comment on it's compatibility with the design method At lot of the introductory stuff seems to overlap very well (ADO entities represent DDD aggregates, entities, and valueobjects), and the mapping provider seems to provide us with a MSFT implementation of the Data Mapper pattern. I wonder if there are any "gotchas" in the implementation though. I'm planning to play with the bits very soon, but was interested to hear the comments of others (esp any MS guys familiar with DDD). ...Show All

• .NET Development Adding new Data Source Problem - happens with VStudio (C#) and Express (C#)

  Hello- I am receiving the same error message within Visual C# Express Edition as well as Visual Studio 2005 when I attempt to add a new data source in my project. The error I keep recieving in both Visual C# Express and Visual Studio is "An error occured while creating the new data source: Could not get the type information for 'Lesson09.Database1DataSet' ".

• Visual C++ Visual Studio 2005 & MFC

  I have a MFC/C++ app developed under eVC 3.0 (i.e., eMbedded Visual C++ 3.0). This allows my app to run on handhelds running with the Mobile 5.0 or Mobile 2003 operating systems. I know that eVC 4.0 can build and link this MFC app, as-is, into a "unmanaged app" that can run natively in a CE.NET environment. Can Visual Studio 2005 perform the same kind of build and link of the MFC app, that eVC 4.0 can do Thank you for your input, msdnrookie ...Show All

  Hi, How can I change backcolor for odd rows to gray, and even rows to white in a datagridview It's not only quicker but it is more efficient.

• Visual C# Wrong Empty string convertion, wrong XML save!

  Hi, I have a wierd issue in my C# code. When I update a field in an XML file with a empty string, the field is actually updated with "\r\n " I try several things like String.Empty but nothing is working correctly. Does anybody have a clue how to resolve this Thanks, Bertrand Hi Michael, I actually believe that the core problem is when the Xml file is saved. My code is XmlNodeList elemList17 = doc.GetElementsByTagName( "Machine" ); elemList17[0].InnerText = ( String .IsNullOrEmpty( this .SEMachineID.Text) string .Empty : this .SEMachineID .Text); /// there the text is OK "" doc.Save(filename); after the saving, it is now "\r\n ".

• Visual Studio Express Editions Can this be done?

  Hi, i have 2 pictureboxes 'A' and 'B', 'A' is a black rectangle box and 'B' is a blue circle. How do i make 'B' overlap 'A' and only the circle is show in the rectangle box without the picturebox blocking out the other details Thanks. Mario Thanks alot for the example. I figured it out. Basically set one of the picture as background. Next put in a pictureBox1 and set backcolor to transparent, the pictureBox1 will take the background picture as it's background. Now import in the picture which also has a transparent background into pictureBox1. Place pictureBox1 at the desired location and you are done. ...Show All
