Visual C# Help with PadRight Method
I am trying to learn the new way of printing (as opposed to the "old" VB 6.0 way). Everywhere I've looked so far shows nice even columns of data printed out. All of the examples assume that the data fields are going to be equal in length. I have been unable to find anything (even MSDN/Microsoft) that explains how to code for variable length print fields. Can anyone please either show me how to print variable length fields so that the report prints aligned columns, or are there any web sites/books available This is the resulting report, my feeble attempt at coding the print routine is below (I've listed only the pertinate lines): NOTE: All of the data is on one line, there are no ...Show All
.NET Development Error when calling an Async WebService method multiple times
Hey folks, I've run into an interesting problem. I'm calling a web service method asynchronously multiple times simultaneously and an error is being thrown despite my calling of the method with unique state objects. The error is: "There was an error during asynchronous processing. Unique state object is required for multiple asynchronous simultaneous operations to be outstanding." In order to make simultaneous asynchronous calls to a web service, one must use a UserState object. In my case, I use Guid.NewGuid.ToString() in each of my asynchronous method calls. After about about 100 - 200 calls, the completion delegate is called, but there is an error. The "AsyncCompletedEventArgs e" argument contains ...Show All

Visual Studio Express Editions C# and Web Page Properties
Hi I'm writing a C# application which takes a list of web page urls and compares a stored version of each page with the current online version. If the online version is different to the stored page then the stored page is updated and flags are set indicating to the user that a page has changed. My main problem is how do i access the modified and page size of web pages I'm thinking that the best way to do this is to compare the page size in bytes and the last modified date with each stored page. If this isn't the best way to do things, please could you advise what would be a better way. Thanks in advance Kev Hi, The following code will retrieve the requested page only when it was modified mo ...Show All
Gadgets addImageObject rotation causes corruption if Margin isn't 0
In the following example, the aliased surround around the image is not placed correctly. Sidebar doesn't take account of the body Margin's. blank.png is a 100% transparent image test.png is a solid white image 300x400 <BODY style="position:absolute; width:500px; height:500px;" > <g:background id="bodyBackground" src="blank.png" style="width:100%; height:100%" /> </BODY> Then add an image to it in code and rotate it: bodyImageSurround = bodyBackground.addImageObject("test.png", 50, 50); bodyImageSurround.rotation = 30; You now have a rotated image, with the aliased surround in completely the wrong place! If you add "margin:0px;" to the body style, the aliased surround is placed correctly. ...Show All
SQL Server Some questions about indices
Hi all, we're planing to create a simple database with will work like a cache for a slow legacy system. The main work of this DB is to give results for search-queries. Each table will have up to 15 columns of different Datatypes and could contain up to 1.000.000 records. example columns of a Table: ID(int), guid (Uniqueidentifier), Subject(varchar(max)), Body(varchar(MAX)), IsComplet(bit), Startdate(DateTime), EndDate(DateTime) and so on... Typical searchqueries may be ("give me all items of a specific StartDate wich are complete" or "Give the item with the guid 'xxx-xxx...'. But also other combination are possible. Currently there are indices for the ID and guid columns. What is now the best practice to configure performan ...Show All

There is an incorrect behavior with the winform combobox. When I write on the text area of the combobox the cursor disappear, but if a move the mouse, it appear immediately. This is not a big problem, but, when I write and the cursor disappear and then I press F4 to dropdown the list, then if a move de mouse, the cursor doesn't appear until I close the dropdown list.

Windows Live Developer Forums NEW API AND MAP CONTROL
Hi all- I'm happy to announce that the latest VE map control went live last night! You'll notice we rolled up some of your suggestions and bug reports into this latest release, and added a couple of really nice new features. Here's a quick summary: 1. Custom tile layers: use MapCruncher or some other tool to create map tiles, and now you can easily add them to your mashup! I've got an example on the interactive SDK that adds a LIDAR image over the map; it took me 10 minutes in MapCruncher and 5 minutes with the APIs. 2. Polygons. We added a VEPolygon object that's a lot like the VEPolyline object except that it also supports polygon filling. 3. Address disabmiguation. We've added a VESearchResult object that returns when you do ...Show All

Windows Forms Combining ClickOnce and MSI Installer
Hi, I have been surprised by the gap there is between ClickOnce and MSI. And I need to solve this. The scenario is this: Install a windows form application on a client (registry values, files, folder creation) and use ClickOnce to just update the application. Any GOOD documents about it Thanks!!! OK. Let me try to explain: 1.- You will need to create an Installation project (MSI) and finally get your app.msi file. 2.- Need to download the Bootstrapper SDK which contains the Bootstrapper Manifest Generator ( http://www.gotdotnet.com/workspaces/workspace.aspx id=ddb4f08c-7d7c-4f44-a009-ea19fc812545 ) 3.- Now you need to create a Package Manifest. 3.1 – need to add the MSI you just generated. 3.2 – Follow ...Show All
