• Visual Studio Tools for Office Excel Application Object question

  I'm currently trying to make a program that interacts with Excel.  Problem is that when I'm editing a cell directly and try to change the property of ANY cell, the program crashes and says I can't edit the property (stuff like ColorIndex). How on earth can I detect if a cell is currently being edited I'm using the Excel application version that is from Office XP, not Office 2003. There is detailed discussion about Excel Edit mode issues with macro in this VBA forum thread: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=158493&SiteID=1 Seems like you may be able to use Application.Ready ...Show All

• Visual Studio Team System source control node sometimes disconnected

• Windows Forms How to handle Ctrl-Drag on design surface?

  Hi, We've got a custom designer working, we can drag items from our toolbox onto the design surface without any problem. However, we want to handle dragging while holding down control - this should create a copy of the control. When ctrl-dragging, the icon changes to a + to indicate that this is what it's going to do, but on releasing the mouse, nothing happens! The MSDN magazine example from March 2006 has the same 'feature'. What do we have to do to enable the creation of the new control Many thanks, Gary Hi, A drag and ctrl-drag off the toolbox should be handled the same way. It doesn't really make sense to m ...Show All

• Visual Studio Secure Method to Deploy Web Project to Web Server

  Is anyone aware of a secure method to deploy a web project to a web server from SourceSafe 2005 Based on the documentation it only discusses using regular FTP or a UNC. Can it be done with WebDav, HTTPS or some other secure method Thanks! Paul Paul, SourceSafe does not support the methodologies you mentioned. If you have Visual Studio, you may be able to manage and deploy your web project from the Visual Studio IDE using these methods. -Brad ...Show All

• Visual C# Uploading image and then overwriting it?

  I'm making a windows app that allows a user to save an image to their profile. If the user uploads a file and clicks save it works. But if they do it again without restarting the program, I get an IO Exception: "The process cannot access the file 'C:\Program Files\karl\Bosch\dealer_logo.jpg' because it is being used by another process."

• Game Technologies: DirectX, XNA, XACT, etc. TransformedTextured depth (Z) values

  I am using 2 TransformedTextured vertex buffers in my scene: 1 for the background 1 prop I assumed that the Z value was a value between 0 and 1; where 1.0 was the back of the scene. This works well for the background, so with this thought, I also assumed then that z=0.5 would place the plane halfway between the front clipping plane. But this does not appear to be the case. The Z value definitely has an impact on the plane's position between the front and back clipping planes, but does not behave as I would have expected. Can anyone shed some light as to how the Z value of a TransformedTextured buffer is used ...Show All

• Windows Live Developer Forums BOTS on MSN

  There have been a number of questions about BOTS in the forum in various theads so I thought I would provide this post with a broader update on the topic. MSN has recently started licensing BOTS on the network.  The huge benefit of a licensed BOT is that it will have contact limitations removed (the reverse list), so that millions of people could connect to the same ID.  Our goal is to enable a broad network of these IM applications integrated with other MSN services (Activity API, Search, etc.). To make sure our customers have the best experience with these applications and provide tools to the broadest number of companies se ...Show All
