• Visual C# how can i get a substring in a string and then change its color?

  for example if I type /* in the textfield all preceding characters should change to color green and when I type */ the change should stop.

• Visual C++ Failure to rebuild after .hpp files are modified

  I've just installed the released version of Vsiual C++ 2005 Express after being a beta user for months. I used the uninstall tool and the installation went smoothly, but I find that now projects don't always get rebuilt when they should. I'm not using explicit makefiles or anything fancy, just ordinary console application Win32 projects generated by the wizard. After I modify a .hpp file that is included by a .cpp file in the project, whether o ...Show All

• Software Development for Windows Vista ServicedComponent shared Transaction

  A more general question about how Transactions are promoted and propageted: Considering I have a COM+ Server Application with multiple ServicedComponents, I have a client making use of multiple ServicedComponents and the clients wants the calls to the serviced components to be transactional. The ServicedComponents are not JustInTimeActivated and support therefore not the "old" transactional style. A client would do the following: u ...Show All

• Visual Studio Loading Help slow...

  On my Dell Dimension 8200 (1.8 GHz, 512 MB RAM, Windows XP/Pro) loading help in Visual Studio 2005 is very slow. It takes up to two minutes (!) before the help screen opens in its own window after choosing Help from the menue or pressing Ctrl-F1, H (or some other letter). Once opened, performance is o.k. until I restart Visual Studio (having closed all instances). During load I can't do anything in Visual Studio 2005 whithout getting a "Delay No ...Show All

• Windows Forms OpenFileDialog: limited no of files

  My application uses an openFileDialog to allow the user to select multiple files for processing. Sometimes quite a lot of files (9000+) which breaks the application. It seems that there is a limit to how many files the user can select. When this limit is exceeded, the FileNames property array does not contain all the files selected and the last filename in the array gets truncated. The truncation depends on the actual length of the names of t ...Show All

• Windows Forms ref a value on existing instance of a form

  I am trying to get access from form2 (opened by form1) to a textbox value on form1.  I created a public variable in form1 to store the value of the textbox in form1.  I know how to get an instance of a new form and get that value, but it doesn't do me any good because the data is not loaded in the new instance.  I need to get the value of the variable from the existing instance.  I have found the following on google, but I ca ...Show All

• Visual C# Enter button sensitivity in Console Apps (C# Express)

  Hi I've been trying to run a program which asks a user for coordinates of several lines.  The code then uses pythagoras to calculate the length of these lines.  However, the problem that I'm having is when a user enters the first coordinate and presses enter, they get no opportunity to enter the remaining ones.  It's alomost as though whne the enter button is pressed, the program thinks it has been hit more than once and skips ...Show All

• Visual Studio Team System many applications sharing framework projects, and each on a different version

  I have several applications that share a set of framework projects. Each application uses a different version of the framework projects. Can I check out multiple versions to support multiple checked-out applications, or do I have to check out separately It might sound goofy at first, but originally we just created project references to the framework projects. But this assumed that all of our applications would always use the latest version ...Show All
