• .NET Development Default Values with a DataSet and SQL Server Express don't work at the table level

  I am new to SQL Server Express and have worked with datasets a little, I am just not sure what I am doing wrong here... When I create a new row with a dataset, the table columns 'Default Values' properties inside of SQL Server Express do not work. If I use the database tools to insert a new record; those 'Default Values' that are in the column properties do get transposed or inserted into the new row for that particlular column if there is no other input. But... if I insert a new row with a dataset; NONE of those 'Default Values' are inserted if there is no value input for ...Show All

• Visual Studio Team System Using a deployment report in a setup project

  Is there any way to use the deployment report generated by the Deployment Designer to specify the assemblies and settings for a setup project Background - as I understand it... The System Designer allows you to specify a system for a given datacentre diagram (as produced by the Logical Datacentre) using one or more application diagrams (as produced by the Application Designer). The Deployment Designer then allows you to bind applications from the application diagrams to hosts in the datacentre diagram and validate that all necessary contraints are met. The output of the Deployment Designer is a deployment diagram an ...Show All

• Visual Studio 2008 (Pre-release) Some viewbox questions

  Hello, I'm using the viewbox to show a part of an image. This image has the following properties: -72 dpi -1024*1280 1. When working with images that are not 96 DPI, be aware that if your ViewboxUnits are “Absolute”, these units do not correspond to image texels. All units in WCP unless explicitly specified otherwise are interpreted to be in dips* or 1/96 th inches. This means that 96 “Absolute” ViewBox units cover one inch of image space, not 96 image texels. If your image has dimensions 100x100 but is at 72 DPI, then the image is considered to be 100 dots / 72 DPI = 1.38888 inches x 1.38888 inches, or 1.38888 inches * 96 dips / inch = ...Show All

• Visual Studio Tools for Office Bug fix request

  Hi; There is one bug I hope gets fixed in Office 12. (Fixing it in a service pack for Office 9 - 11 would be really nice too.) Sometimes the menus I add to Word stop calling my event handlers. A very easy way to see this happen is open two instances of Word, close the first instance of Word, then close the document (but not Word itself) of the second instance. The menu objects will now fault if you access the enabled property and they will no longer call the event handlers for the menus. thanks - dave Hi; I'm not disagreeing with you. I was already doing what you suggested . I just want to make sure MS fixes it so there are no exception ...Show All
