• .NET Development ERR - WebClient.DownloadData returns "protocol violation"

  I'm getting a "protocol violation" from a site that is working perfectly fine when I issue WebClient.DownloadData as such: WebClient WebClient_Temp = new WebClient(); byte[] zbyteTemp = WebClient_Temp.DownloadData ( "http://MySite/MyWebPage.htm" ); I have heard of the app.config file fix, but my app is a UserControl, and as such, I can not keep the "MyApp.dll.config" in the same directory as such: <configuration> <system.net> <settings> <httpWebRequest useUnsafeHeaderParsing = "true" /> </settings> </system.net> </configuration> I've also tried putting a <link> element into m ...Show All

• SQL Server Finding database size in SQL Express

  Our system guy wants me to find out just exactly how much room is being taken up by the SQL Express databases (I am using two). I am not sure how to do this. Is there any way to find the size, or, lacking that, how many records overall We will probably need to move up to SQL 2005 soon, but he needs to figure out the memory requirements, etc. Thanks, Michael try select [size] from sys.database_files This will give you a row for each primary datafile and log, to get it all in one statement you could use select Sum([size]) as total_file_size from sys.database_files ...Show All

• Visual Basic 2 Textfiles in DataSet

  Hey there I have a problem: I import 2 textfiles (they are saved in the same folder and TabDelimited) with the Visual Studio 2005 wizard into a DataSet. Now I'd like to do a SQL query which gives me all the records that are in one table but not in the other one. But here I got an error. I tried some ways in query builder but it seems that a query through 2 textfiles isn't possible. When I select a row from only one textfile the query runs without problems. As soon as I add the second table it doesn't work. Can you tell me if it's really impossible to do a query through 2 textfiles And if yes, how could I solve ...Show All

• Visual Studio Team System How do I derive from TestContext class and implement from base members

  So, I see a lot of people are looking at this. But no one is responding to it.  It would be great if someone would be able to at least check the answer to verify it.  ---------- Im lazy, and somewhat new to OO.

• Visual C++ Converting System::String to Int32 and back again in hex in C++

  OK, I have a simple question: I have a window where a user can enter a hex value, like 10BF00D1. Another one where the user can enter a pure binary number like 1000011101101001. I want to grab the String and put the data into an integer, manipulate it and turn the result back into a String. How do I do this with the managed System::String class in Visual C++ 2005 It was easy to do back in the "C" world, why is it so hard to find the new way Thanks, Dale Hi, To do the conversion you should use Convert::ToInt32. By the way, if your are going to do a lot of .NET programming Managed C+ ...Show All

• SQL Server What is the performance difference between using varchar fields of vastly different sizes?

  I was wondering what the performance diffeneces/issues there are between using  varchar fields of largely different sizes ie varchar(100) vs. varchar(5000)  From what I have read SQL Server only stores the actual bytes of the data written to the field, so data 50 bytes long would be stored the same in a field of varchar(100) or varchar(5000). Everywhere I look people say to use the smallest size possible but given few if any reasons for this logic.  I would love to hear from someone that knows the inside details of why if any this affects performance. The reason I am interested is that we are building an application that may ...Show All

• Visual Studio Express Editions Error after deployment

  I have created a Windows app in VB 2005 Express and it runs OK on my development machine, it does give one error which I assume is to do with a demo version of a componenet which has a nag screen.  When the nag screen goes away, so does the error message. I have published the app and installed it on another machine.  Whenever I try to run it, I get a 'has encountersed a problem and needs to close' error.  My question is: is this error the same one I see (that goes away) on my dev machine or something more fundamental to do with the deployment I would prefer to not install VB Express on the other machine and compile the projec ...Show All

• SQL Server How can I get value from data flow control?

  How can I get value from data flow control when it returns to the Control flow I want to use values in the data flow to decide what I'm doing next - using an expression  on the 'line' (i.e. @Step == 10, 20 , 30 ...) @Step  - is user defined variable. How can I set @Step according to the data flow It seems to be that I can't change @Step in the data flow. Seems like you are editing Script Task instead of Data Flow Script Transform (or maybe Data Flow Script Component, but Source instead of Transform). Of course, it is possible the script task (or existing task, e.g. Execute SQL Task) is ...Show All
