• Visual Studio 2008 (Pre-release) DataSet Serialization errpr with nettcp Binding

  The following is tested under .Net 3.0 RC1. We have found an anomaly in serializing DataSets across a WCF service. When we send a Dataset over WCF to update back to the database, we perform some server side validations. If there are errors, we set either the RowError string on the DataRow with the error, or (usually) the ColumnError for the column within the row associated with the error. Upon return from the service, the Dataset is merged with a dataset bound to GUI elements, the column errors cause the error provider to light up and the user knows to correct the problems. Unfortunately, we discovered, that, whether passing the Dataset back as a return from the service method or as a ref parameter, only the RowError was preserv ...Show All

• .NET Development Bit manipulation

  Hi! We would like to see if C# (1.1) has any API to manipulate bit in that way: For example, send a variable to it, like a INT64 and ask that function is such bit is 1 or 0; like... Int64 test = 255; bool bit = CheckBit(test, 5); and that CheckBit would return if the 5th bit is 1 or 0... We know how to write that function, and it's simple, but we always prefer to use the standard API, and we don't know if C# 1.1 has that already. Thanks in advance Yep, it does. BitConverter can convert your Int64 to an array of bytes, System.Collections.BitArray is available to manipulate the bits. For example: Int64 v = 255; System.Collections.BitArray vec = new System.Collections.BitArray(BitConverter.GetBytes(v)) ...Show All

• Visual Studio Tools for Office Problem with punctuation after a control inserted at runtime.

  Hello I am working with vsto 2005 (.net 2.0) . I created a default dot file that opened with custom task pane but i missed some information about the way the documents (base on this dot) knows about the dll. I know about the manifest file and about the property at the doc but i am getting problem when i opened the documents if the dot file is not at the same plcae it was when i first created the document. How can i force the document to know about its DLL Thanks in advance Sharon :-) Why would you have moved the *.dot file Generally, Word documents can only find their "partent" template if it's in the same location, or at least in a default path or a path in the Windows "PATH" environment. ...Show All

• Visual Studio Express Editions Re-drawing items in picture box

  I have a program that draws a graph in a picturebox (using DrawLine, DrawString). My problem is that the picture box goes blank if the program is minimised and parts of the contents are erased if another program is brought in front of it. There must be a better solution than having a 'refresh graph' button. Help much appreciated. Thank you Mike ...Show All

• SQL Server Problem with dates format passed as parameters...

  Hi, I am having the " classical problem " of the forums; A local date changed to the american format (normally in the development environment) which I call "Switching months with days"... well it switches both again if you press "view report" again :) The problem I'm having is that when I Navigate from one report to other, the dates get switched...

• Game Technologies: DirectX, XNA, XACT, etc. Rants on XNA 1.0

  This is my first reaction when I installed and tried the 1.0 of XNA. To summarize my feeling: it's still 95% for XBox and no nearer to replace the old MDX 1.0. So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the contents are only built before the program runs. The helper functions wrapping D3DX can only be used with types in the content pipeline. I have to utilize the full content pipeline just for generating something dynamically, of course with significant performance cost. Or I have to write those D3DX utilities my self. Currently I don't have a good id ...Show All

• Visual C# Thread Message Suggestions

  I have a question. In my C++ days, I had straight C++ threads using thread messages to act very similiar to MFC UI threads to process messages even though they weren't connected to a UI. The Win32 calls included ::CreateThread(), ::PostThreadMessage(), ::GetMessage() to simulate the behavior of just dropping a message into a thread queue to process the message. Now that I am in C## land, I can't seem to find any documentation about thread messages which tells me that I am looking at the problem incorrectly meaning C## does things differently. Suggestion Yes, I do realize this What I am looking for is a suggestion as to either the "official" C# way to accomplish my desired behavior or just restru ...Show All

• Windows Forms Problems with "Show Dialog" and Large amounts of data

  I have an inventory lookup form, called from many different user controls, that could easily be loaded with large amounts of data (150000+rows). My problem is that with only 22000 test records it takes about 35 seconds to load. This would be acceptable if I could load it up the first time and then simply hide it. The problem is that the ".showdialog " method of the form, while it works and allows me to pass the selected ID to the calling form, brings up a new instance every time causing the delay reloading every time. In VB6 you could hide the form then show it again and pass a global variable containing the selected ID from one form to another. In VB.net 2005 the Only way to pass the variable from the one form to the other, ...Show All

• SQL Server Feeding an "IN" Clause

  I know I can supply an explicit set to an IN clause, or I can feed it with a select statement. What other ways in TSQL 2005 can I feed it One thing I'd like to do is feed an IN clause by calling a stored procedure. I'm new to TSQL, so I don't know if I can do that. I'd also like to know if there is a way to pass a variadic list of values as a parameter to a stored procedure, so that they can be used in an "IN" clause found in that stored procedure. I think the way to do that last item is by having a recordset parameter. Is that correct Any other way to do it My apologies for making a mistake. The method I presented in my previous post should work, but the implementation is a little off. The corrected code should be... ...Show All

  When I log into Windows Live Mail through IE, the paine size (not the text) is too large, I can not see the bottom of my e-mails nor can I see the far right.

Since it is native .NET Managed provider, you cannot use Provider property in a connection string, it already knows that it is SQL Server.

• Visual Studio 2008 (Pre-release) XBAP and browser cookies (not working)

  When an XBAP application calls Application.GetCookies(), it throws an exception (due to no cookies). The browser window hosting the XBAP application does have cookies for the site. This is CRITICAL in developing an XBAP application that interacts with a web server - the forms authentication and session cookies need to be maintained between the initial browser request and the XBAP application that it is hosting. How can I get the XBAP and browser to use the same cookies Not all session cookies can/should be persisted, and the developer does not have control of some cookies.
