• .NET Development DataSet serialization problem through remoting (VS2005 release)

  Hello, I have a problem with a client/server application using remoting (TCP channel on the same host) and DataSet. The server loads successfully an xml file using a typed DataSet (built by xml schema designer and MSDataSetGenerator), it also writes data back to the xml file without any problem. Everything seems to work fine on the server side. But, when the client tries to get the DataSet via remoting I get an exception: -  $exception {System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Data.DataException: Invalid 'Key' node inside constraint named ...Show All

• Visual Basic StreamWriter giving me fits! much background and code ;^)

  Let me apologize now for the length of this post…. This has me stumped (not that that’s hard to do). Let me give some background. I am creating a “sweeping” program for my FTP server (local, located in my office) that will use the filesystemwatcher to look for new folders (containing .wav or .dss files) as they are being uploaded and move them to a central location. Two of my major concerns for this app are the slow upload process for some of my clients, and that if the FTP server computer, or the app itself should freeze or be accidentally turned off (or we lose power past my backup’s battery capacity, etc. etc), th ...Show All

• .NET Development Help with apostrophe symbols in database items

  I am using Visual Studio 2005 pro and C#. I am converting part of my application to work in SQL database, but I have a slight technical difficulty to get over. My application decodes a file which contains names and stores them into a database. However, some of the records in the decoded file contains the apostrophe ' symbol which causes problems with my varchar strings that I need to build and send to the SQL database, for example, the name " St. James' " contains the apostrophe symbol which is also a termination of a varchar string in SQL syntaxes. Is there any way I can get around this Also, if I need to drop/adjust t ...Show All

• SQL Server How to hide a column in chart

  Hi all, Is there a way to tell Reporting Service not to display a column in the chart For example, I has a bar chart report now has two bars represent column A and column B. I want to be able to display the column B value in the table below the chart. But on the chart, I don't want to display the bar that represent the column B value. Can I do that by modifying the RDL file How Can someone give me an example code in the RDL Thanks in advance You cannot hide columns in the chart - but in this particular case you could use filters instead (e.g. on the chart level, or at the category/series grouping level) ...Show All

• Visual C++ Function or algorithum for finding a value

  Hi, im currently trying to make s simple program that calculates a formula that the searching paramether cannot be calculated directly, its something like : 1/x = z.log10(x+y) where we know the value of Y and Z and need to find a fitting one for X. So my question is: Is there a function that can do the things easier or I got to find myself the value that works, and what algorithum to use Thx a lot Yes. . I think it can be solved via analytical methods. I think you can calculate the derivative, and analyze that. email me with particulars. I got my calc and dif eq's books dusted off. ...Show All

• SQL Server What exactly can sp_executesql parametrize?

  I am attempting to create dynamic SQL with sp_executesql. However, it seems that parameters can't be created arbitrarily in the query string. In particular, the name of the table apparently can't be parametrized, or I am doing something wrong. I use SQL Server 2000 with the latest service pack. The table task has a few columns of which TaskID is Primary Key and INT. This works fine: DECLARE @pot nvarchar(200) SET @pot = 1 DECLARE @pot2 nvarchar(200) SET @pot2 = 'task' EXEC sp_executesql N'SELECT * FROM task WHERE TaskID = @pot', N'@pot varchar(128), @pot2 varchar(128)', @pot, @pot2 However, this does not work: DECLARE @p ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Getting rendered graphics (quickly) from the card

  I had a thread about thins some days back, but for some reason I can not write into it now. I am faced with the task of rendering some graphics with directx and then copying that graphics into another card which generates a video signal. I need to feed it a new frame 25 times a second. The size is 720*576 The rendering does not have to be any faster that this. I have tried two methods of geting the pixels, and both are much too slow. One takes 500ms for a frame and the other 1800ms. I need a time below 40 for this to work. I post the two methods below. Perhaps someone can provide input as to what I need to do. I might add that ot ...Show All

• Visual C++ Cannot set VC++ Directories in the Options dialog of Visual C++ Express Edition

  Details :  The VC++ Directories page on the Options dialog does not have a list box for viewing and modifying the directories used during a build. Consequently, it is not possible to modify the build directories using the IDE UI. Workaround : C++ Directories can be added, removed or changed by modifying the VCProjectEngine.dll.express.config file located in the .\vc\vcpackages subdirectory of the Visual C++ Express Edition install location in a text editor, saving the changes and restarting the Visual C++ Express Edition. Please make sure that you also delete the file "vccomponents.dat" located in the "%USERPROFILE%\Local Settings\Ap ...Show All

I would like to know if I can copy and use the mfc libs and headers in the Visual Studio 2005 Express Thanks Victor No! 1. The Express Version has no Resource Editor. 2.
