• Windows Forms Datagrid "Focused Grey Box" problem?

    Hi Everyone, I have got 2 grids and they behave like master and detail grids. One grid lists all the order and 2nd one lists all the items for the Order. All the orders are filled in Top grid and when user click on different orders its items are shown. Now when user clicks on product on orderitem grid(below) and then clicks on other Order in Top Grid the orderitem grids leaves a focused cell(Grey Box) on the cell clicked. i have implemented the functionality of colouring the cells from this example http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnwinforms/html/wnf_CustDataGrid.asp I have temporarliy uploaded the screenshot at following location to get the clear picture. ...Show All

• Visual C# __DATE__ equivalent

  I'm new to C# coming from a C background. I would simply like access to the build date of my application. In C, I could do this using the __DATE__ macro. How would I do this in Visual C# TIA JeffM OK, I was close... It is "days since 1/1/2000" -- this code will work: Assembly assem = Assembly .GetExecutingAssembly(); Version vers = assem.GetName().Version; DateTime buildDate = new DateTime (2000, 1, 1).AddDays(vers.Build).AddSeconds(vers.Revision * 2); Console .WriteLine(vers.ToString()); Console .WriteLine(buildDate.ToString()); ...Show All

• Visual Studio 2008 (Pre-release) WCF hosting: NT Service X IIS?

  Hi Everybody! We are starting a new project for a high available web system and we are thinking about using WCF to provide the required services. Probably we will use server clusters in order to provide the required availability, but we don't know yet if the solution shall use 3 levels of clustering (web, application/business and database) or 2 (web/application and database) as it depends on the customer budget. I'd like to know which solution would be more suitable: hosting the WCF services as NT Services or within IIS. Could you help me regarding the pros/cons of using each one considering: 1 - How easy each one adapts to the clustering hardware solution 2- Performance 3 - Security ...Show All

• Windows Forms How to total up a column in datagridview?

  Hi, I have a datagridviewComboBox which specify the ProductName and after user choose the product, the Qty as well as Unit Price, the LineTotal will reflect the total amount for that row. I need to add up all the rows od LineTotal and put the total amount into a textbox. How can I go about doing this Thanks There are many places you could place this code, but in your case, where you're binding your DGV to a data table, try catching the ColumnChanged event of your data table (dt) - whenever the value of that column would change (goes for every row), this event will be triggered and the sum recalculated. Also, you need not to Dim result as new decimal. Instead, this would do: Dim result As Decimal = dt.Comput ...Show All

• Windows Forms Vista UAC and ClickOnce Issues

  Hi, I am working on certifying our applications on Vista. I'm running Vista RC2 build 5744 and Visual Studio 2005 with SP1 Beta. The issue I have is that, as a certification requirement, applications have to be proven to install and run under a limited user account. I have no problem with that requirement in theory but in practise this seems to be a totally different matter given the tools available. I have done a lot of testing using ClickOnce publishing under different scenarios but there are some difficulties and inconsistencies. In the end I used a simple "smart client" windows application with just one form. Our deployment scenario would be similar. I tested different trust levels etc. Now this is what I found: ...Show All
