Windows Forms Preserve offset of vertical scrollbar
Hi (This is about the DataGridView control). I have a DataSet with two different DataTable s. The tables are: "Groups", groupID (PK), name. "Users", userID (PK), groupID (FK), fullname, age. I then create a DataTable , T , having the merged information of the two tables above. For instance: "George", 22, "Administrator" (<fullname>, <age>, <Groups.name>) instead of "George", 22, 1 (<fullname>, <age>, <groupID>) Now I set T as the DataSource of the DataGridView . The scenario: 1. User scrolls down the vertical scrollbar. 2. User creates a row (by adding information to the User table). 3. The DataSource is then updated. ( T is recreated) How can I pr ...Show All

Windows Live Developer Forums Tile overlays in V4 3D using GetTilePath
Is anyone successfully overlaying tiles using the dynamic "GetTilePath" property on the VETileSourceSpecification in V4 3D ...our V3 2D application when switched over to V4 3D no longer works :-( - it does work in V4 2D. Yes, you've hit a known bug. Using % for the parameters was a poor choice because it's common to see them in URI's. The workaround is to not have URL's with HTML encoded characters in them (like %20 or %2c). The zoom level and tile LOD listed in the manifest are the same. There is no schedule for 2D supporting the full set of parameters yet. ...Show All
Visual Studio Vista Compatability problem with VSIP package
I implemented VSIP package which works under VS2003/2005 with WinXP/W2K. Inside our package, there is a functionality which writes different messages to the log file. After migrating to Vista, that functionality did not work because of "Access to the path 'XXXX' is denied.". After reviewing some Vista Compatability articles, I found that we need requestedExecutionLevel = highestAvailable which should be in app manifest. But our app is "devenv" and we cannot change its manifest. Is there a solution to run VSIP package with highestAvailable execution level Yes, you are right, when the devenv.exe run with Administrator credentials everything works well. But we cannot suggest users t ...Show All

Visual Studio How to add a reference node in a custom project
In our VSTS SKU (VSTS for Database professionals), we have sql server projects which contain sql code and generate .sql file on being built. At present there is no reference node appearing inside the project node. Wonder what exactly is needed to have it there. I expect to add other database projects references to a database project. Thanks Sachin Kumar (MSFT VSTS-Data) Hi Sachin Kumar, Take a look to open source project WiX http://wix.sourceforge.net/ . It includes Votive (Visual Studio package - WiX project integration). Votive uses custom references. So you can find the sample of custom references implementation. Good luck! ...Show All

Visual Basic Data Searching/Copying
Hi, I am currently doing a project that entails me searching directories for particular data, which will then return information to the user, the user selects the data needed then copies it to a certain directory. For example just say I wanted the info: A12345, I want a search to be performed, after clicking the search button, but the code tailored to all possibilities of files in these folders, i.e. B45678 and so on. Two directories have to be searched for this information. After that I want the file information for the specific file to be displayed on screen to the user, who can then select the information they need. Then finally I want that file information copied from one of the previous directories th ...Show All
.NET Development Object must implement IConvertible
I am using remoting to pass data from a server to a client (or clients). It has worked really well until we had some DNS problems yesterday. Now I am getting an InvalidCastException with the message "Object must implement IConvertible". The strange thing is that I'm only getting this message on one machine -- I haven't tested it on every machine but out of 5 machines, it's only happening on one. The error occurs when the server tries to call a client method, one of the parameters is a class which has the [Serializable] attribute set. The really strange thing is that it says it can't convert [ClassName] to [ClassName] where ClassName is the name of my class. Both machines (the machine hosting the client and the machine hosti ...Show All

SQL Server Poor performance querying view from sproc
We are using SQL SERVER 2005. We have been experiencing horrible performance running select queries from sprocs against views that do outer joins, despite having optimized all of the indexes. Our solution in these cases (and arguably not the best) has been to first select the views into a temp table and then query the temp table for the desired result set. This has greatly improved the speed of which our sprocs run, but we are looking for a better solution. Has anybody else experienced this problem Thanks in advance. Hi Eric. Would it be possible for you to post some sample code that includes some of the view definitions, table structures, and sample data scripts It's quite tough to try and g ...Show All
