• .NET Development how to create Download Accelerator

  Hi Masters, Any one have idea how to create Download Accelerator in .net 2005, i have worked in vb6 there was a component "inet" which is capable to upload and download from the server. i am looking for this type of component in .net2005 any one have idea pls inform me Awating for reply.................... Thanks I am guessing that you are looking for more than just the ability to download a file, but want to be able to download multiple parts of the file at once. If that is the case WebRequest or HttpRequest (which extends WebRequest) would be your best bet for doing this sort of thing, otherwise for simply file gettings, WebClient can’t be beaten for it’s simplicity. ...Show All

• SQL Server omitting null columns

  Hey everyone, I haven't got any idea where to even start looking for a solution to this problem so any help would be appreciated. I'm trying to write a stored procedure that will return a table yet omit any columns that don't have anything written to them, so any columns that have no data will not be present in the table returned after the stored procedure. Thanks in advance. Menace is right: The dynamic SQL to accomplish what you want is pretty ugly. Here is an example of one way to do it: create table dbo.example ( column_01 integer, column_02 float, column_03 integer, column_04 varchar(30) ) go insert into example values (1, null, 2, 'This is a test.') insert into example values (2, null, null, ...Show All

• Visual Studio Tools for Office Word Addin: Event for new Document object

  I want to get event when new Document object is added into Application.Documents collection. I was looking for this event for a while and was unable to find it. I found Application.NewDocument event, but it's fired only if you click on New... button in Word (it isn't fired if you just run Word.exe). Am I missing something I know that in Oulook Addin there is an event ExplorersClass.New for new Explorer, but in Word there is no DocumentsClass class (only Documents interface and it doesn't have any events). Ok. But the problem with those events is that if I just open MS Word (by clicking on icon or launching word.exe) neither of those events are fired (even though new Document is created).

• Visual Studio Tools for Office How to export data to Excel file effectively

  I need to export a set of data , which may be stored in a DataTable object, to an Excel file as a report. Taking advantage of "Excel 11.0 object library", it is quite simple to do the job. But the interop between the managed code and the unmanaged COM component turns out to be too ineffective. I have to handle Excel.Range to insert data to the Excel cells. In order to improve the performance, I convert the data into an array, which can be inserted as a whole. The problem is: the display of the table gridlines should change according to the data, so I can not get rid of handling a large amount of Excel.Range objects. For instance, string[,] dataArray = LoadData(); Excel.Range range = _worksheet.get_range(" ...Show All

• SQL Server CREATE XML SCHEMA COLLECTION ddl statement???

  what's the purpose of defining a "relational schema name" in the CREATE XML SCHEMA COLLECTION ddl statement i don't understand why it's an option.

So when you create table "MyTable", its full name dbo.MyTable or Sales.MyTable etc. For more examples, please, see database AdventureWorks.

• Windows Forms Glass effects with .net

  Well, this is really a comment and a question: I posted a sample on .net (windows forms) and glass using the Dwm functions to do frame extend, sheet of glass, full client blur, arbitrary client blur - on my blog ( http://philiprieck.com/blog/archive/2006/07/21/GlassForm.aspx ) Just one problem: Anyone know of a fix for the "must paint black over glass" limitation that doesn't resort to using a WS_LAYERED (aka transparency key) window Painting black isn't really a problem - it's putting winforms controls on top of it - the background and foreground gets all messed up. Any help would be appreciated. Thanks, Philip That certainly seems to be true - hopefully GDI+ is better - but it l ...Show All

• Windows Forms want to share the same instance of a user control on separate tab pages of a tabcontrol.

  i have a c# user control being used on a tab page within a tab control in a vb.net winforms project public class SplitterViewControl : System.Windows.Forms. UserControl { Is there a way to reuse the same instance of that control on each separate tab page If I drag the usercontrol onto each separate tab page, I get what I would expect. SplitterViewControl2 then SplitterViewControl3. How could I access the SplitterControl1 from across the tab pages I hope the question makes sense.

• Visual Studio 2008 (Pre-release) I can see https site but not able to download by svcutil

  Hello. Well, a couple of days ago, I put a post concerning this sample. . Since Vista was released, I'm using IIS7. (over http, I've been running the samples successfully)And I'm trying WCFSamples\TechnologySamples\Basic\Binding\WS\TransportSecurity sample. Before I just couldn't get to see the page that had https. Now I can access it by IE. But it always says that there's certification error. I don't know why cause I used the setup.bat that came with it. Anyway, I think because of it, when I try the following command svcutil https://localhost/servicemodelsamples/service.svc , I cannot download the metadata because of the certification error. Is there any solution to this How can I make this certification error disappear ...Show All

• Visual C++ Arrays of Strings

  Hi folks, I'm writing a .NET Winforms project in Managed C++ using Visual Studio 2003 and I'm wondering how I go about having multi-dimensional arrays for String objects I'm vaguely aware of the Array Class, but I'm not sure if this needs to be part of my solution. I've tried a few experiments using the classic C++ method of creating multidimensional arrays, but (of course) this does not work owing to the managed restrictions of the language. In any case, I just need a little direction here - do I need the Array class or is the syntax for this a bit different than what you might expect -Zero In VS2003 you need something like this (tested in VS2005 with /clr:oldSyntax because I don't have VS2003 ...Show All

• Visual Basic Accessing images stored in Access database with VB.NET 2003

  Hi, I am developping an employee management application with VB. I used an Access database to store employee information and the pictures. However I have a difficulty at displaying employee images. I have found some code to add images and display them on the form. The code, first reads the image stored in database (in binary form) then writes in a temp file and then uses a picturebox to display the image on the form. Code is working fine but when I try to add a picture for an employee and then try to change (another add operation) the employee's picture right after addition, program crashes because the temp file is already in use.
