• Visual C++ Installation Issue Visual C++ 6.0 on Windows XP

  Hi folks, I have an old copy of Visual Studio 6.0. I've attempted installing it on two different machines: a Toshiba Laptop running WinXP Pro SP2, and an HP Desktop running WinXP Home SP2. Both machines are fairly current (< 3 years old). On either machine, the installation aborts unsuccessfully before completing the installation. If there is an error message, it is not presented to me to review. The install had gotten far enough that I could compile, so I've ignored the problem up until now. However, I'd like to install SP5, and it tries to detect the installed components and fails to do so- presumably because the installation never successfully finished. Any ideas I dimly recall this worked once long ago. ...Show All

  Hi all, Is there any enum for Range.Insert() method's CopyOrigin param ZeroCool127, Being an optional parameter you can always use Type.Missing to get the default behavior. To answer your question you can use the XlInserFormatOrigin enumeration. //Default behavior range.Insert( Microsoft.Office.Interop.Excel. XlInsertShiftDirection .xlShiftDown, System. Type .Missing); //Enumeration range.Insert( Microsoft.Office.Interop.Excel. XlInsertShiftDirection .xlShiftDown, Microsoft.Office.Interop.Excel.

• .NET Development Debug interfaces in real time

  I am thinking of using debugging interfaces to provide flexible diagnostic extensibility to an application running in production. This involves having application to instantiate the debugging interfaces internally and define some breakpoints that will be hit as the application executes (I read about separate debugger thread in 2.0). The code inside the breakpoint will then do some diagnostic activity and let the application go until the next breakpoint is hit. So this is kind of applicaiton debugging itself in its own process at certain points of its execution. Do you think using the debugging interfaces will even be feasible to produce something like this And that it will be stable and have little performance degradation compared to un ...Show All

• Visual C# Help with a 'Delete' MessageBox

  Hi I am pretty new to C# and VS2005 so I am sorry if this sounds like a stupid question but; I am trying to create a messagebox like the one that appears when you attempt to delete something in windows. Form1 has fields for editing data into an SQL database which works fine from a control within Form1. I have created a new form (form2) and can get it to display no problem but what I can’t do is get the button on form2 to run the script for deleting the data on form1. "On form1 user wants to delete data from database, clicks delete, messagebox pops up (form2) 'Are you Sure', user clicks 'yes' form2 disappears, and data is deleted". (This is what I am trying to achieve). Currently all databinding etc ...Show All

• SQL Server OO Database Design performance question

  I am hoping someone has had a similar table design scenario and has a slick solution that i am not thinking of. Basically I have the following tables (kind of OO based design in this case). Create Table Entity (EntityID int, EntityTypeID) Create Table Company (EntityID, CompanyName) Create Table Contact (EntityID, FirstName, LastName) Create Table Group (EntityID, GroupName) Basically an Entity can be a Company, a Contact or a Group based on the EntityTypeID The trick becomes when I get an EntityID is how to get the name of the Entity in an efficient manner. You can make a view that does a Union to all three tables like such... select CompanyName as Name from Company union all Select FirstName + LastName ...Show All

• Visual Studio 2008 (Pre-release) Frame doesn't render when AllowTransparency = True

  I created a new project in Blend, added a Frame to the default presented grid, and set the Source to "http://www.google.com". The app worked perfectly. After closing the app, and setting "AllowTransparency" to true on the default root Window causes the frame to be rendered white. The navigation happens, and the mouse pointer changes shapes over links, but nothing is rendered to the Frame. Is there a way to solve this problem I am creating a window with a custom window border that is not rectangular, so I need AllowTransparency to be true on the Window object (if there is another way to do this, any info would be great). It's an educated guess, but Frames displaying html use the ie mshtml engine in a separ ...Show All
