• Software Development for Windows Vista Problem with Drag & Drop

  Hi! I have the following problem: In my workflow designer host application I have a toolbox implementing ItoolboxService like in the Designer Rehosting example. When I drag items from the toolbox onto the design surface, a correct drag item is shown along with the name of the activity. But when I drop them on the surface, I get a NullReferenceException in the overriden OnDragDrop event of the root activities designer, more precisely when base.OnDragDrop is called. The Activity DragEventArgs seem to be correct tho... When I use the ToolboxService class of the Designer Rehosting example, everything works fine. Although I use exactly the same serialization/deserialization methods as the example... (and the Activity DragE ...Show All

• Visual FoxPro problem with class

  i get the error ole error class is not registered...... what does this mean and how do i fix it i read the vfp help files on it but it was too confusing for me.

Then run the following command either using Start->Run or using the command prompt - REGSVR32 COMCTL32.OCX ...Show All

• Windows Forms datagrid troubles with stored procedure (vs 2003)

  I have the following code: Dim daGrid1 As New SqlDataAdapter(Me.SqlCommand1) (a stored proc) Dim dsGrid1 As New DataSet dsGrid1.Clear() daGrid1.Fill(dsGrid1, "top") DataGrid1.DataSource = dsGrid1.Tables("top").DefaultView I set the command to a stored proce and fill a dataset, then set the datagrid1 to the dataset table. I can then see the data grid on the form filled out. I need to change the column headings, hide some columns, then click on a row, and get the hidden field and pass it on to another form. I thought I would need a table style for that. But when I try to add one, I get: "The data grid table styles collection already contains a table style with the same mapping name." ...Show All

• Visual Studio Team System Proxy statistics website not available

  I have been logging about my proxy problems already in some other thread but haven't got that much response. ( http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1216865&SiteID=1 ) So this is a new post with a new problem that hopefully could lead to a resolution for the other problems as well. When I try to access the statistics page, I'm getting a login dialog and whatever account I use it always ends up in an "Access Denied" error. I installed Fiddler to find out what really happens.

• Visual Studio Express Editions Locking Mouse

  Hi ive been looking for days to find the code that will lock "Block" the mouse move event from being processed... So far i've tried the code: actHook= new UserActivityHook (); actHook.OnMouseActivity+= new MouseEventHandler (MouseMoved); public void MouseMoved( object sender, MouseEventArgs e) { Cursor .Position = Ace; } where Ace is the point that the mouse was at last. This doesn't work unfortunatly as i can still move the mouse around... That event is hooked with a class called UserActivityHook (declared as actHook) (not my class) UserActivityHook public event MouseEventHandler OnMouseActivity; I'm thinking that Cursor .Position is only repainting the cursor and while the mouse ...Show All

• SQL Server SIMPLE QUESTION !!

  This might be a very dumb question but "is there an easy way to obtain only the name of the fields from a table" I am sure there is but as you might have guess I am just a starter who cannot figure it out. Any code is appreciated for the same. Thanks! NEVILLE GEORGE The best solution might be using the INFORMATION_SCHEMA.COLUMNS system view. You need not join the SYSCOLUMNS & SYSOBJECT tables here. The System View does it for you :) You can fetch the following information from this view.. Table_Name Column_Name Ordinal_Position Column_Default Is_Nullable Data_Type Character_Maximum_Length Character_Octet_Length Numeric_Precision Numeric_Precision_Radix Numeric_Scale Datetime_ ...Show All

• Audio and Video Development Superimposition filter with MF

  Hi, I've been working for a little time with Media Foundation, trying to implement an application I had once created with DShow. This is a C# form using a wrapper and a filter to play a video file applying a transform. With DShow, I was able to write a filter to write on the video, using a HBITMAP and the m_pinput properties in the CTransformFilter Class. In MF, I'm not able to reproduce the same process like that. So my question is : "Is it possible to write a filter with MF, which would allow to write on the video (using Superimposition) Thanks The Grayscale MFT sample is there mostly to show you around the mechanics of implementing an MFT; of course we expect MFTs in the wild to be doing somethin ...Show All

  Hi, I like to know if we can delete the documents in the document object library using a program written in C# or VB or any other language Thanks, Lokeya yes, but the application (the program) would have to run on the sharepoint server itself. Alternatively you can write a web service that gets a url of a document to delete and deletes it. ...Show All
