• Smart Device Development Working with multiple forms and using form text

  Hi All, I am working with multiple forms form1 and form2, I have added form text to each of the form. On a button control in form1 I have added the below code, which loads form2 and hides form1 but in the taskmanager it shows both forms at the same time. I have tried using an empty text in form2 and it works. Is it possible to show the form1 text on the top of the titlebar in form2 when it is activated instead of empty titlebar. Dim frm1 As New frmMain frm1.showdialog or frm1.show netcf v2 added support for "owned dialogs". In the code below, when I set the Form.Owner proper ...Show All

• Visual Studio 2008 (Pre-release) IEnumerable enhancements

  So what happens if you try querying over a generator that doesn't have a finite length   For example: from n in Integers...   Probably not a good thing. What happens if you have a sequence that you want to get the length of   Sometimes you can't, without pulling all the data ahead of time.  Sometimes, you can't because the sequence (such as Integers) is infinitely long. Could the definitions of IEnumerable, IList, etc, be written to include such information   I'd propose some interfaces: IFiniteList -- marker:  the list has a finite number of elements IBoundedList -- provides Length, which is known ahead ...Show All

• SQL Server Help on replication from SQL 2005 to DB2/AS400

  I was trying to set up a replication process to move data from SQL 2005 to DB2/AS400. To get it started, I have create a simplest table (say, PERSON) on SQL 2005 server, and the same table (PERSON) on DB2/AS400. I have only one column SSN (of type int). I have journaled the table on DB2 end. I was able to have successfully configured publisher (on SQL 2005) and subscriber (i.e. a pushed subscription). I used transactional replication. And I also installed HIS 2004 to have DB2OLEDB ready. I was able to use query/insert/delete against table on DB2 based the linked server (that I created for testing purpose). I did a lot of reading on t ...Show All

• Visual Studio Where's the Help Integration Kit 2005

  I briefly tested the Help Integration Kit 2003 in VS2003. Now I've updated to VS2005 and would like to integrate my library docs with MSDN, but don't know how. Help 2 seems to be a bit of a secret since there's precious little information available. One MSDN article directed me to the Visual Studio Extensibility Center but there's now info on Help 2. Does Help Integration Kit 2005 exists and if so, where can I find it If not, how can I (easily) integrate my own docs with MSDN OK, finally managed to download the SDK (huge problems signing in). HelpSudio Lite seems like an excellent app. Even importing my ...Show All

• Visual Studio Tools for Office building solution containing VSTO on CruiseControl.NET?

  I'm trying to build a .NET 2.0 solution containing VSTO on CruiseControl.NET 1.0. I have the .NET 2.0 SDK installed and regular .NET projects build fine using msbuild. .NET 1.1 solutions with VSTO for VS2003 build fine as well. The 2.0 VSTO project fails because a number of files are missing. Fair enough, but there doesn't seem to be a VSTO SDK I could install. The VSTO runtime does not contain all the files required to build and I cannot install VSTO itself because there's no Office on my build server (it should be as clean as possible). I started by copying all the files it complained about, but I end up with an error message : C:\Pro ...Show All

• Visual C++ Mouse click and color

  I'm currently using Visual C++.net 2003 version. Let's say I've displayed a color spectrum pattern from a bitmap  file on a windows form. So, from left to right, the color  transitions from red to orange to yellow to green to blue to indigo to violet. Now let's say I need to be able to left click anywhere on that color spectrum and determine what the color (or Red-Green-Blue combination) is where I've clicked. What I mean is, I can gather information like the x position and the y position of the pointer, but I need to know what that color is right there. The position of the mouse doesn't do me any good because the RGB c ...Show All

• Visual C++ Strange Clock Skew problem

  I've been trying to track down the problem causing this to happen but am at a lose as to where else to look. Maybe someone here can point me in a new direction. Here's the problem. During normal business hours, the server's clock is skewing by multiple seconds per hour. It sometime skews forward and sometimes backward. After 8 hours, the clock is sometimes off by minutes, and it appears random as to if it's fast or slow. But while the application is not running, the clock does not skew. My application runs on a dedicated server. It is C++ unmanaged code with lots of threads (100s+) all reading and writing to 1000s of files simultaneous ...Show All

• Visual Basic specifying relative folder paths

  Hi -- I've built a simple Windows application with VS2005 and I'm having a problem with specifying folder names.
