• Visual Studio 2008 (Pre-release) WPF apps slow for some reason

  Everything is slow for some reason. I tried Max, and that ran decently (aside some weirdness I'll explain below), but I try running some of the sample code and other stuff I compile on Visual Studio, and it's unbelievably slow. I tried the samples here  on XamlPad... I can click on a button at a rate of about 2-3 times a second, and my CPU usage will jolt up to 100%. Most other sample applications run just as slow. Max runs okay, except that it takes about 40% of my CPU time even when it's minimized. By the way, is there something I can do about text being blurry Here are some of my machine specs: Pentium 4c 2.4ghz HT 1gb DDR 400 dual ...Show All

• Visual Studio Team System BUG: Invalid handle on concurrent checkout/checkin

  If I am checking out the a project file. My colleque checks out the same project file (concurrent checkout) Then he checks in the project file. Now, when I am trying to check it in I get an error box saying "Invalid Handle" Restart, Reconnect to TFS doesnt help. However, If I do a "Get lastest version" then it triggers a merge request, after I done the merge, the checkin works fine. Regards Fredrik Melin After further review on our merge issue it appeared that it had something to do with line endings.  The merge tool showed half of the code updated which none of the code had been touched.  When we put in a diff ...Show All

• SQL Server Bug in SQL Server 2005 ? - DATEADD function

  Hi When I execute the following , the expected result is 03/31/2006. However the result that you get is 2006-03-28 00:00:00.000 Select DATEADD ( MONTH , 1 , '02/28/2006' ) Is this something how the dateadd is supposed to behave or is this a bug in SQL Server 2005. Regards Imtiaz Hi Imtiaz, I can't actually see anything wrong here. Why would the expected result be 31 March 2006 That is not one month in the future, that is one month and x days. What you are trying for is a "End of Month" function... Cheers Rob ...Show All

• Windows Forms Unhooking Parent events

  I have a control that needs to hook a couple of it's parents events so I'm planning on overriding the OnParentChanged event. Where is the proper place to unhook these events if the parent changes As far as I can tell, you don't have access to the previous parent in the OnParentChanged event. Thanks, Ray OnParentChanged would be the best place to handle this, you just need to store a reference to the previous parent, for example: private Control _PreviousParent; protected override void OnParentChanged(EventArgs e) {     base .OnParentChanged(e);     if (_PreviousParent! ...Show All

I am working on a webpage that scans the network and displays the amount of time since last boot. I currently use if (System.IO.

• Visual Studio Tools for Office Find() and Autofit() issues

  I have 2 questions related to the Find() and Autofit() methods: I have a VSTO application that opens an Excel.Workbook wb, goes through all the worksheets via "wsCurrent = wb.Sheets as Excel.Worksheet", and then uses the Find() method on a specific column ("rngFoo = wsCurrent.Columns["A",missing] as Excel.Range") to find a value. I have applied the same logic to different type of columns successfully, except with one because the Find() function is not able to find a result. The only difference with other columns is that the values in this column represent a number with 9 digits. The worksheet was exported from a text file. Th ...Show All

  Hello. I am calling a sub workflow from a work flow via the "invokeWorkflow" shape. Here is my problem. The sub workflow returns a value that is displayed via a web service.

• Visual C# FileSystemWatcher - InternalBufferSize

  Hi, Using VS2005, C# - project is a converted VS2003 service program. I have a problem setting the InternalBufferSize of a FileSystemWatcher object. I've created a service program to monitor a folder for changes. I instantiate the FileSystemWatcher then apply the path, etc settings. Finally I set the InternalBufferSize property to 16384 and enable the FileSystemWatcher. The project builds fine but when I start the service I get an error message saying the path is in an invalid format. If I remove the change of the InternalBufferSize property this error does not occur. Is there a sequence I should follow for assigning the ...Show All
