• Visual Studio 2008 (Pre-release) Working with a Canvas in Cider Designer

  When working with canvasses in the Cider Designer, I can't select it to move it around, and I can't seem to drop anything on it, I have to add with XAML, and if add the items in that way, the items themselves are not moveable or sizeable. Is there a bug fix for this Thank you, Jaco There is currently no support for interacting with container controls other than the Grid. Much of the work we have done in previous iterations focused on improving the overall quality of the features (such as working with the Grid) in the CTPs. We have decided to remove some functionality that was present in previous CT ...Show All

• .NET Development How to decrease Form startup time?

  Hello, I have a .NET Form that displays the contents of a directory.  It works fine, but it can take 5 to 10 seconds to start and display.  If I close it and start it again, it starts faster.  How can the Form start time be decreased so the Form displays faster Thanks Mister T Another possibility is this simply has to do with caching... When you do a cold start, everything needs to be looked up off the hard disk to memory, which takes quite a bit of time.  Subsequent uses may take advatage of bits of that data persisting somewhere aside from the hard disk, also there could be code around ...Show All

• Microsoft ISV Community Center Forums Getting Excel Formulas to work in VBA

  I have formulas that need to be copied and pasted to the next row down from the original. The problem I ran into was when a formula that refrences some data on a hidden sheet tried to run it will bring up a dialog box wanting to know what file to use to Update the values. I need this formula to work without asking for updates. Here is the formula and the values it wants: Current Excel Formula = IF(M12 > 0, IF(M12 > 7630, ('Conductivity to TDS '!$C$3 * EXP((('Conductivity to TDS '!$D$3 - LN('Data '!M12)) ^ 2) / 'Conductivity to TDS '!$E$3)), ('Conductivity to TDS '!$C$4 * EXP((('Conductivity to TDS '!$D$4 - LN('Data'!M12)) ^ 2) ...Show All

• Visual C++ "list iterator not decrementable", error.

  I am trying to use some code written in C++, by a third party and I am having problems with the run time error: list iterator not decrementable I am using VS 2005. I have limited C++ experience by the way. This happens when an STL list, in decrementing backwards, pass the beginning of the list. I am told that the list is ‘Circular’, so this should not matter because it will hit the end of the list. This code has run on VS2005 before, by other parties, so I am a bit stuck!

• Visual Studio Express Editions Adjusting the width of a ListBox to it's contents

  VB.net Express I would like to adjust the width of a ListBox to the width of the largest item it contains. Is there any way to do so Thanks by advance for your answers, Pierre Leclerc Pierre, There must be a way to find the width of an individual item but I couldn't find it. Hopefully somebody else will read this and inform us both. In the mean time, I was able to get it to work with the following code. You will have to adjust your _factor variable depending on the font type that you are using. A factor of 6 worked for the default font. Private Sub Button1_Click( ByVal sender As S ...Show All

I do, multiple times and it still gives me the same loop of crap. Any suggestions would be appreciated greatly! I think I found my solution, ...Show All
