• SQL Server Chart does not display when Toolbar=False

  I have a basic bar chart that runs fine on a local 32 bit server both within an IFRAME and within the reports manager. However, on another server that is brand new and clean install of SQL Server 2005 (64 bit) that same chart will run fine within reports manager but not through a direct link (whether in an IFRAME or not). I narrowed the problem down to the parameter Toolbar=False. If I leave off that parameter, the report runs fine but includes the header. If I set the parameter to True, it also displays fine with a direct link. I can also specify Parameters=False and that works fine. However, no matter what I try, setting Toolbar=False returns a report (showing text in textboxes) but the chart itself returns as an image placeholder wit ...Show All

• .NET Development In C#, what is the difference between System.String and System.string (lowercase)

  This mignt not be the correct forum, if so, I'm sorry about that. I am trying to get a better understanding of the .NET library. I am programming in c# and I see that System.String (uppercase String) and System.string (lowercase string) seem to be the same objects. However they are color coded in different colors. I am guessing that there is a reason, but I cannot seem to find it in the documentation. Can anyone shed some light on this Thanks! Bob Mark Benningfield wrote: Hello All. Bob: Here's another thread that thrashes your question. It might shed some light. HTH. Thanks Mark that does help. But I still have a question about the color coding of the two k ...Show All

• SQL Server Problem with Transaction Logs

  Hi, I have a big problem with transaction log. I need to reduce the transaction log file becouse, the have 25 GB, but when i run the statement for BACKUP LOG with TUNCATE_ONLY, dont work, becouse i have database mirroring installed. Please is very urgent. Hi Guillermo, If your mirroirng state is synchronized, you will keep the transaction log under control by periodically backing up the log. How frequently do you backup the log Looks like you generate 25 GB of log per day. If you would like to keep the transaction log size under check, you would probably like to back the log more frequently. Sanjay ...Show All

• Visual Basic Windows Media Player Control not working as it did with VB .NET Express

  I just learned how to use the Windows Media Player control and I had a Windows form working that would connect to a URL and play the video. When I tried to add the control to an ASP .NET website, there were two options for WMP...a dll file and an ocx file. I added the dll file to my toolbox items, but it doesn't show up in the toolbox like it did in VB. I managed to write code without errors that is supposed to do the same thing as my Windows form, but I can't drop the WMP control on the page, so nothing happens. Can someone help me figure out how to put the control on the form so I can see it I'll show you the code that I have which worked in VB Express.

• Visual C# confused with runtime error and compiletime error

  class B { int32 x; } class D:B { int32 y; } B b = new System.Object(); //This statement will cause a compile time error. D d = (D)b; //This statement will cause a runtime error. I am really confused, I can't find out the differences between the two statements above, I think they are the same.Who knows why Any help will be appreciated. You can cast from a derived class object to a base class object but not the other way around. Class D has two members (x and y), class B has one member (x). You can't convert a B object to a D object, there wouldn't be any value for the 'y' member. The compile-time error is similar. Class B inherits from Object. You could keep the compiler happy with: B b = (B) ...Show All

• .NET Development Web.Config file error

  I need to use impersonation in my web.config file for a web service. I have done this in many web services on different servers already, so I know that it should work. I add the following to my web.config file: < system.web > < identity impersonate ="true" userName ="*****" password ="*****"/> </ system.web > But, as soon as I add this, the WS breaks. When I take this identity tag out, it works again. I've tried impersonating different accounts to make sure the problem was not with a specific character in either the username or password, but it still did not work. Any ideas I found a fix for this, http://support.microsoft.com/ ...Show All

• Windows Forms ToolstripManager

  I am trying to work with toolstrips. I have added the loadsettings and the savesettings. My toolstrip settings will save and load properly if the toolstrip is on either side or the bottom, but when the toolstrip is on the top the settings are not loaded correctly. Is there a fix for this or some special code that must be used to get the toptoolstrip to load correctly The positions of the toolstrips are not correct. The easiest way to see the problem is to create a sample app with a form. Put a toolstripcontainer on the form. Add one toolstrip. In the form load event add toolstripmanager.loadsettings(me) and in the form closing event add toolstripmanager.savesettings(me). Run the app and move the toolstrip across the top of the form t ...Show All

• Visual Studio Team System Do you need VSTS for Testers to create a Test List for execution by MSBuild?

  My developers are using VSTS for Developers to create and run unit tests on their own PCs. However, there doesn't seem to be an easy way for them to add these unit tests to our Integration Build (Build Lab) PC so they will be run as part of MSBuild. At the moment they have to logon to the Integration Build PC (which has VSTS for Testers) and then add their unit tests to the Test List that is executed as part of MSBuild. Is there any other solution apart from installing VSTS for Testers on each developer's PC ($$$) Will FWIW, here's another thread tracking the same issue: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=129079&SiteID=1 Eric Jarvi http://blogs.msdn.com/ejarvi ...Show All

• Visual Studio 2008 (Pre-release) Returning an array of types defined with a data contract.

  I have a method that looks like: ReturnType[] A(RequestType request) The ReturnType is defined in the data contract. I am not sure how to define a message contract for an array of types defined with data contract. I think that is why I am getting the following error: The operation 'A' could not be loaded because it has a parameter or return type of type System.ServiceModel.Channels.Message or a type that has MessageContractAttribute and other parameters of different types. When using System.ServiceModel.Channels.Message or types with MessageContractAttribute, the method must not use any other types of parameters.
