• Visual C# Exposing properties

  Hi! My idea is to include into language a mechanism to expose a field's properties. Let's say I'm inside some WinForms user controll. My control's got a label named label1. I want to expose the Text proprety of the label inside my user controll class and call it LabelText. The main pattern idea is to 'inherit' all the child's property attributes automaticly (like DefaultValue, Browsable and so on - these are just examples, Text proprety's got some others). I would only have to write single line of code that would do everything for me, like public LabelText = label1.Text; One problem I've noticed is that some of the attributes may be of private nested inside that class types, like class MyClass { [AttributeUsage(Attribut ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. SWM Model Component

  Hi all! I just finished a simplified version of a swm loader component based on the classes in SpaceWars. I used X-Tatic's converter to transform the tiny.x model into swm http://astaroth.beatbuggy.net:8080/Downloads/x2swm_1_0_0_1.zip I sent the sources to www.xnaspot.com  , hopefuly, they will put it online soon. P.S. the smaple also includes components for a grid, and for FPS (which can be set to be displayed in the titlebar, screen or both)   Have Fun!   Catalin Zima  P.S. I also wait for XNAspot to post my sample of VertexTextureFetch in XNA ;) Attention: Zima Catalin I have a little present for you, I have attached a set of folders with al ...Show All

• Visual Studio 2008 (Pre-release) LINQ and Atlas

  Ok so what I am trying to do is have a form with a textbox for a search dialog. On keypress I want to query top 25 records and display them in a gridview, so as you type it refines the search etc. So I have hooked up all the atlas javascript methods etc but I am not sure if I am able to do this or not. Basically my webservice code looks like (generated with BLINQ): return from dom in db.Domains select dom; So this should return all my records (fine for now in testing) and my javascript receiving function does the following: function OnComplete(result) { var d = document.getElementById( "<%# grid1.ClientID %>" ); d.DataSource = result; d.DataBind(); } This results in an error of: System.InvalidOperati ...Show All

• Windows Forms Datagridview comboBox not showing displayMember

  I am creating a comboBox in a dataGridView that holds month values. The dataGridView is bound to a datatable which is created from an SQL query. However, this DataTable also contains additional columns that I am creating and populating in code. In particular, I am craeting a "month" column in the DataTable in code after the DataTable is filled from an OdbcDataAdapter. I am trying to add a combo box to my datagrid that will represent my months column, but for some reason, the combobox will display the month ID as opposed to the month name once the combo box has lost the focus. For example, if I select "April" from the combo box, the value will revert to "4" when the combo box has lost focus. As far as I know ...Show All

• Visual Studio 2008 (Pre-release) Issues with generating .net 2.0 client for consuming a WCF service

  hi all, I have created a WCF service and specified message contracts for defining how a request should be sent when invoking a WCF method and also the response. I am using a Windows Service to host the WCF service. The service runs fine and there are no issues with that. The problem is when I try to generate the proxy class (.Net 2.0 client), I am getting a warning as shown below Warning: This web reference does not conform to WS-I Basic Profile v1.1.

• Windows Forms Listbox to show options from a related table

  On a Windows form, I have textboxes to show data rows of a main table. The main table has a foreign key to a minor table which is a list of status values ("Pending", "In Progress" and "Done"). The object is to display the status in a listbox or combobox. I want to know how to do this. Some notes: 1) The code to set up connections, DataAdapters, CommandBuilders, bindingsources, Datasets, etc works fine. 2) I would like to set up any constructs in code rather than with a wizard. 3) Unless I have to I want to avoid creating the relationship between the tables in the wizard. 4) I get the sense that one Dataset can access and update both tables, but I don't know how to tell the dataset about additional tables. ...Show All

• Visual C# Keeping a logfile

  I am new to C#. I want to know what is the best way to keep a log of what you do in an application The log will be a file of some sort which can be added to but not updated. There should be an easy way of reading from the file. Oh, you don't need to implement it - when you make the GetLogger() call, it will automatically create a logger of the type you've specified in the config file - in my case, a RollingFileAppender, as you see in the config file I posted. There are several other types, if you look at the documentation. But you don't need to know any of that - you just make the GetLogger call and it'll create an instance for you that you can use. No need to implement the ILog interface. This is the be ...Show All

• Visual Studio 2008 (Pre-release) Can WCF help me.

  Hi, I've been tasked with writing an app that will allow a single scanning system to provide data to multiple programs on a network. In a nutshell, a single PC will be connected via serial cable to scanning hardware. The new app will detect the scan via comm port, then transmit data over the network. There are presently 3 vb6 apps, on different PCs, that need to listen for and recieve the data. Each of these apps will be expecting data from only a single scanner which is identified by ID in its transmission. This will allow my client to have a single scanning system for all software requirements. I was envisaging a WCF app on the scan connected PC, this will have a list of the IPs of the LAN PCs and a list of the scanner IDs, this will ...Show All

• SQL Server Combine raw files using range

  HI, I have a dataflow that has two raw files as source and I would like to merge them upon a range condition: RawFile1.Date <= RawFile2.Date Usually, using tables, I would have used a lookup with partial cache to achieve it. Now, since we cannot use lookup transform with raw files, I was wondering how I could achieve this using raw files as source. Is it possible to merge raw files using merge or merge join Thank you, Ccote ccote wrote: Thank you both for your inputs. I will have to revise the design of this package.

• SQL Server CRI Designer Adornment class - host WinForms controls?

  Hi, I'm developing a CRI and in design mode I would like to have some controls on my adornment windows. Is there a way to use WinForms controls here instead of redefining the wheels... Thomas That is one possible solution. You don't have much flexibility to dynamically change the appearance of your adornment, but you can intercept mouse movements and clicks. You can create a dialog that is invoked by clicking in the adornment. -Albert ...Show All

• SQL Server sql express bootstrapping question...
