• .NET Development Why Tables.Rows.Count is 0 even though rows are displayed in DataGrid

  1. I have a webforms application. 2. I am checking the number of rows is higher than 0 if (DataSet1.Tables(0).Rows.Count() > 0) 3. The value is always 0 even though I have retrieved rows from this DataTable into my DataGrid. Any Ideas Please help.. This occurs in Web-Forms Applications. I thought you only have to fill in the DataSet once. And then be able to use the data contained in it on any future call. But the data is reset when a Post Back occurs. So I am filling up the dataset again in the Page_Load(). Making sure it is not within a "If Not (Page.IsPostBack)" statement. If anybody knows of a better method(where I would only call the DB once) please let me know. ...Show All

• Smart Device Development Logical NOT (!) operator broken? What's happening?

  Does anyone have any idea why the logical not operator might not be working in Visual Studio 2005 compiling for ARMv4 Consider the following code. int test = -1; int test2 = !test; TCHAR temp[256]; wsprintf(temp, _T( "%d" ), test2); if (!test) ::MessageBox(NULL, _T( "Not!" ), _T( "Result" ), MB_OK); else ::MessageBox(NULL, temp, _T( "Result" ), MB_OK); The correct result is a messagebox which says "Not!", right Instead I get a messagebox saying "0" - that's wrong! Can anyone else duplicate this What could possibly be causing it >int test = -1 >if (!test) (Why can't I [enter] and get a single-space LF ) You still have to wa ...Show All

• Software Development for Windows Vista Writing Resource Managers for System.Transactions to MTS/DTC and XA

  We are trying to write a durable resource manager that works with System.Transactions. I need to use mts/dtc talking to xa where the actual database is on a remote system. I have read all of "Implementing a Resource Manager" and everything else I could find but could not figure out how to couple the .NET resource manager with xa. We have working distributed transaction code for OLEDB and ODBC using mts/dtc and xa. I really need sample code and/or hints about writing such a resource manager like this. When you say "couple the .NET resource manager with xa" what is the scenario you are trying to hit Are you referring to setting up a 1Pipe/2Pipe connection to an XA enabled Resource Manager using a System.Tra ...Show All

• Visual C++ Looping through struct/class data members

  Hi, I'm hunting for some elegant way to loop through all the members of a class (or struct), without having to name them specifically. I have several very large structs, and I want to read in their values (say from a text file) using some kind of loop. Is there a way to dynamically find out 1) how many members a struct/class has and 2) their names I thought the starting point might be something like a pointer to a specific data member in a class (I'll have to make classes out of my structs): class clsMyClass { int i; float f; clsUserType c; } clsMyClass objMyClass; int clsMyClass::*ptrMyClass; ptrMyClass = &clsMyClass::i; (objMyClass.*ptrMyClass).i = 20; What I want, however, is to be able to make ptrMyClass someho ...Show All

• Windows Forms I know there's an easy answer to this one...

  I have a SQL database connection in my project, and I only need to insert a value into one of the tables. I have created a stored procedure in my database to do this, and I am seeing my "QueriesTableAdapter" with that stored procedure when I edit the dataset. I have one simple form. In my code, I need to call that stored procedure, so I know that I need to somehow add the "Queriestableadapter" control to my project. The "Queriestableadapter" control is not showing up in my toolbox to be able to add it to the form (and, therefore, reference it). I have done this in other projects, but I can't remember how I was able to get it to show up. Help! Thanks! Edit your datasource ...Show All

• Visual Studio 2008 (Pre-release) What is the status of Windows Presentation Foundation Everywhere (WPF/E)?

  Hi, I'm interested in Windows Presentation Foundation Everywhere (WPF/E) as a possible alternative to Adobe Flex development. All the information and blogs that I can find are from back in March to May, e.g. http://blogs.msdn.com/mharsh/ Has anything happened since then What tools do I need to develop in WPF/E Where do I get the browser plug-ins (miniturized CLR for IE, Firefox, and Mac) Thanks, Mark WPF/e is on a different shipping schedule. My original impression is that RTM for WPF/e was at least 6 months after RTM of .NET 3.0. Of course, no one is saying anything. WPF/e is basically an entirely different beast than the full WPF. ...Show All

• Visual C++ Missing icons on MDI child windows

  Having written code to create MDI master and child windows using Win32 API, I have discovered that when using the application under the Windows XP theme, icons assigned to the MDI child only appear when the child is maximized. When the child is minimized or normalized, a white space appears where the icon should be. The icon is assigned using - SetClassLong(widgets[1].hwnd, GCL_HICON, (LONG)geeicon); The icons appear using the same code using Windows 2000 and Windows XP, classic theme. Also if you start the application using classic theme and then change to XP theme the icons stay attached to the child windows. It is only if you start the appication in Windows XP theme that the icons are missing. Any ideas ...Show All
