问题 How can I force my ASP.Net application to connect to a SQL Server using TCP/IP, not Named Pipes? I read somewhere putting "tcp:" in front of the server name in the connectionstring should do the trick, but it does not seem to change anything. Edit1: TCP/IP is enabled on the SQL Server. I tried Network Library=dbmssocn in the connectionstring, I still get an errormessage about named pipes: "provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server" Edit2: Turns out

问题 I'm creating a document viewing web application. You log in and it takes you to a screen where you have all your docs listed on the left. I want to make it so that when you roll over a document a preview of the document shows up on the right. From there you can click on it for a full view and printing capabilities. I'm not asking how to do all that but I'm wondering what the best way would be to go about rendering the preview of the document. The documents are all going to be pdfs and stored

问题 I am trying to publish a ASP.Net 3.5 site to an IIS 7.5 server using WebDAV and each time I do the config file winds up empty.

问题 Basically I am inserting an image using the listviews inserting event, trying to resize an image from the fileupload control, and then save it in a SQL database using LINQ. I found some code to create a new bitmap of the content in the fileupload control, but this was to store it in a file on the server, from this source, but I need to save the bitmap back into the SQL database, which I think I need to convert back into a byte[] format. So how do I convert the bitmap to a byte[] format? If I

问题 I am creating a dynamic array, and getting an error: Error message: Cannot convert type 'string' to 'string[]' The code is: arrTeamMembers += tb.Text; tb.Text contains values such as "Michael | Steve | Thomas | Jeff | Susan | Helen |" I am trying to pass the values from tb.Text to arrTeamMembers. I am NOT trying to split the text. How can I resolve this error? 回答1: You can't just add strings to an array of strings. Depending on what you are actually trying to do, you might want this: string[]

问题 How can I create a subdomain in an asp.net C# application? I am working with an asp.net portal. In that portal I need to be able to create the subdomain at runtime. The ftp for that subdomain also needs to be the same as the main domain ftp. 回答1: There are a handful of working parts here. It sounds like the requirement is that this all happen at runtime. I am sure a lot of web hosting providers are deep into these sets of problems and likely have custom solutions. DNS : you'll need to have an

问题 I have a 32-bit application (targeting .NET 3.5) hosted on a 64-bit machine. I want to analyze the memory dump of this 32-bit application. I captured the memory dump using 32-bit adplus and cdb. I am loading the memory dump into 32-bit windbg. When I load .net 2.0 sos.dll and .net 2.0 mscorwks.dll into windbg and execute !clrstack, I get the following error: "Failed to find runtime DLL (mscorwks.dll), 0x80004005 Extension commands need mscorwks.dll in order to have something to do."

问题 The page has already run its' initialise/load sequences etc but then catches an event. How can I then send value(s) from this event to the client. That probably doesn't make much sense, hopefully this will clarify: I have a grid (Telerik RadGrid) in a user control (A) and when the user selects a row in that grid, I want to update another user control (B) with the selection.
