• Visual Studio Tools for Office Excel Data Binding Performance

  I just updated my Excel VSTO code to use data binding (via ListObject) to a DataSet. Prior to this, I was putting data into a 2-dimensional array and setting it to a range. Now the screen update is significantly slower. We often times will have large DataSets. In one example, I had a DataSet with 10,000 rows, and 20 columns (with floating point data). With data binding, it took close to 1.5 minutes (90 seconds) for the screen to refresh. When I ...Show All

• .NET Development Clipboard.SetDataObject fails unexpected due to security restrictions

  I try to put data on the clipboard by using Clipboard.SetDataObject(data) from an an assembly hosted in Internet Explorer. I've noticed that this call fails if the assembly don't have permission to call unmanaged code. The documentation on SetDataObject only states that UIPermissionClipboard is required though. My question is: How can I put data on the clipboard if the application doesn't have permission to call unmanaged code. And why would ...Show All

• SQL Server multiple conditional formatting

  Hi, is there simplier method of doing multiple conditional formating   right now i have to nest the conditional:  iif(a=b, "Blue", iif(a=c, "Red", iif(a=d, "Green", "Black"))).  so if i have 5/6 or more conditions, it will be very messy. thanks, Ash In some cases (e.g. numeric values), you could use alternatives to the IIF function: * =Choose(...) http://msdn.microsoft.com/library/en-us/vblr7/html ...Show All

• Windows Forms DataBinding - Hardcoding ValueMember and DisplayMember

  Something that always bugged me about data binding in Visual Studio is that you specify the DisplayMember and ValueMember of the binding to be strings that are *supposed* to be properties of the data source. You get no intellisense help when entering these values and, if you spell it wrong or the name of a property changes later, the project still compiles and runs fine until you hit that binding. Is there a way, using reflection or any other m ...Show All

• Visual C# Windows Service - multiple instances

  I want to run multiple instances of the same service on one machine. So I wrote a service installer that looks for three parameters which can be passed in via the installutil.exe. So far so good, I can install multiple instances, but of course it makes no sense that they all do the same and use the same configuration. So I thought I could use the service name (property ServiceName) in the service itself to e.g. look for a configuration secti ...Show All
