• .NET Development well format xml

  Hi,  I get an xml file, which is not well formed, it's structure is like: <groups> <group> <name></name> <desc></desc> <items>  <item>    <name></name>    <desc></desc>  </item> </items> </group> </groups> As you can see, the problem is, that some nodes are defined in different mapping types.

• .NET Development Managed Memory Leak?

  I am having a very strange memory leak that seems related to databinding. It is very hard to reproduce, so I won't post any code here to do so, but will just describe the problem. We have data entry forms which have controls which bind to custom business objects through a BindingSource object. On Dispose of the form, we call ClearBindings as described in: http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnwinforms/html/databinding_winforms10_11.asp#databinding_winforms10_11_topic11 However, our business object stay in memory after the form has been closed ...Show All

• Visual Studio Express Editions App_Data fails to open new item

  I have installed the August CTP of Visual Web Developer 2005 Express edition, along with SQL Server Express and the MSDN Express edition.  SQL Server seems to function properly and I am able to connect to it throught the Database Explorer pane.  It is configured through the ASP.NET Website administration tool and a test of the AspNetSqlProvider confirms a connection to the database. When I try to open a data source or create a new item under App_Data in the Solutions Explorer, I get the following error: Connections to SQL Server files (*.mdf) require SQL Server Express 2005 to function properly.  Please verify the insta ...Show All

• SQL Server Newbie: "Compiling" a DTSx package

  I have now created a few simple SSIS packages. In BIDS I right-clicked on a solution and selected "Build". I went to the "bin" directory hoping to find a standalone ".exe\.dll" file but found only a ".dtsx' file. Can BIDS can actually build a standalone exe\dll or is the .dtsx file all that's available (If so, I guess that another program is expected to invoke the .dtsx file.) TIA, barker In my SSIS package deployments, I've deployed my packages via file system files. Basically, all you get for this is a .dtsx file in your /bin folder. To the best of my ...Show All

• .NET Development .NET Question.

  Hi, im new to .NET C++ programming, and have a simple question to ask. When i create a simple application using Windows Form Creator and add a richTextBox to the form, i get the following code(see below). And Ive added a simple function (EditText()) at the end of the file which isnt in the name space. What i want to know is how can i access the richTextBox1(which i created in the namespace) outside of the namespace. Is that possible Because i'd prefer to have most of my functions in a seperate header file instead of being cramped up into one file. Thanks in advance for any help. #pragma once namespace test_app { ...Show All

• SQL Server navigation on subtotal

  I have a matrix and a subtotal footer summing up a group of numbers. Each row has a primary key. I use the primary key to drill-through another report through "Navigation". Unfortunately, the generated subtotal column also have a link but it has a primary key of whatever the first row is, which shouldn't have a primary key. So I can drill-through the subtotal but it returns the wrong result. I have not been able to override the subtotal to specify a new link with different paramters. Anybody can help would be great! Thanks. In the place where you define the drillthrough action with its parameters, ...Show All

• Visual C++ passing arguments to a System(something.exe) function

  Background : I have an MFC application and a c++ program (separate entities). I did a build on the c++ program, and copy pasted the resultant 'exe' formed in its debug folder into the MFC application's folder. Now in the MFC, I am calling the function "System(mt.exe)", which is a call to the exe that I had copy pasted. Question : This exe (ie the c++ program) uses a variable 'counter' at some point in its execution. Is it possible for me to pass an 'int' as an argument to the exe when its called from the MFC, so that the 'counter' within the exe takes that passed integer as its value So effectively, first time the exe is executed, ...Show All

• Windows Forms Calling MsgBox inside a TabPage's Validating event

  I have a form that contains a tab control. I want to perform (multi-field) user input validation when the user changes tab. If the user input is invalid, I want to display a MsgBox. However, whenever I call MsgBox inside a tabpage's Validating event, this seems to affect the behavior of the comboboxes on that tab page. To see what I mean: 1. Create a new project 2. Create a form 3. On the form add a tabcontrol with 2 tab pages 4. On the first page add a combobox with a few items. 5. Handle the first tab page's Validating event this way: Private Sub TabPage1_Validating( ByVal sender As Object , ByVal e As System.Compon ...Show All
