• Software Development for Windows Vista System.Transactions and MSDTC

  I've recently tried using System.Transactions.TransactionScope to handle my transactions. Although it's very handy and simple to use in my business layer, i cannot get the code to run unless the Distributed Transaction Coordinator service is running on my pc. (SQL Server 2005 is running locally so i can test on a local version of our database) My question is: why does this service need to run if all i'm trying to do should only require a standard Transaction, not a distributed one Is my transaction being promoted (and thus suffering a perf hit) This is the codeblock where i'm using the scope: Dim scope As Transactions.TransactionScope = New Transactions.TransactionScope Dim newname, oldname As String Dim sjabloon ...Show All

• Visual C++ Problem with ReadFile(), used to read from a Asynchronous Pipe

  Hi All, I am getting this unusual problem. I will try to explain as clearly as I can. I am working on two processes in which one is parent and other one is child. Now the STDOUT of the Child process is connected to Parent process using a asynchronous pipe. Now, when I am trying to read the content of STDOUT of the child process using the pipe, the processes get stuck at some point where ReadFile() is used and it doesn't progress further. When I hit CTRL+C to abort the execution, following message appears on the CMD: "The pipe in which you are trying to write doesn't exist" But when I tried to debug it, the pipe handle was still present. Please help me regarding this. Please ask the questions if the problem is no ...Show All

• Visual Studio Tools for Office Outlook Add-in : best way to deploy minor/major updates after using setup project?

  If I initially deploy my Outlook add-in using the setup project (to test for prereqs, grant security and create registry entries), what is the easiest way to deploy minor updates Do I just need to over write the assembly and application manifest files on the target machine What if I want to use the Publish wizard Can I mix the deployment methods in this way or is there an issue with the fact that the publish wizard creates subfolders for updates For more major updates where I need to uninstall the add-in via add/remove programs, how can I code my setup project so that it uninstalls any existing versions of the add-in before trying to update the new version Thanks, Tad Hi Tad, Yes ...Show All

• Windows Forms How to change appearance of toolstrip overflow button?

  Hi there I derived my own class from the toolstrip, to implement a few changes. My toolstrip uses a blue background color. This works fine, but i got a little problem: The overflow button is nearly invisible, until you hover over it with the mouse. It uses the same background color as the toolstrip and only has this little black arrow which is nearly impossible to see with the blue background. I only want to get this button better visible! I tried to change the BackColor and ForeColor properties of the overflow button (which is accessible via toolstrip.OverflowButton), but ForeColor changes nothing at all and BackColor only draws a little line on the button in the desired color. I also tried to write my own ToolstripRenderer. I override th ...Show All

• Visual Studio Express Editions BackColor of text in TextBox

  My application has a search TextBox1 containing a search term. The search results show up in TextBox2. I would like for the search term in TextBox1 to have a yellow backcolor property in TextBox2 to make it easy to find ( like this ). Here is my best attempt so far: Dim searchTerm As String = TextBox1.Text If TextBox2.Text.Contains(searchTerm) Then searchTerm.Format( Of String , BackColor.Yellow)() End If I get an error message: Type 'BackColor.Yellow' is not defined which leads me to wonder if I am heading in the right direction with this code since I am interested in defining a string property value rather than data type. Any thoughts on how to proceed would be appreciated by this VB Newbie. ...Show All
