• Visual Basic Is a ColorMatrix the fastest way to edit bitmaps? (LockBits)

  I've made a function that makes bitmaps transparent via a ColorMatrix but now I'm wondering if that is truly the fastest way, because I can see that it takes a while (not that much, but enough to notice) to update the picture when I use a slider to adjust the transparency. Is there perhaps an imageformat that takes an alpha-value for the whole picture instead of per pixel, so that I don't have to use a colormatrix to go through every pixel to update the transparency Edit1: for example, setting the opacity of a form updates instantly, so how can I change a bitmap's transparency that fast in managed code - or is that just asking too much of VB Edit2: LockBits seems to promise better speeds - examples are welcome :) Edit3: okay, I tried b ...Show All

• Windows Forms Scroll the datagrid to a particular row

  Hi, I have a problem with the vertical scrollbar. I would select a row in datagrid and update it.When I reload the datagrid with data, the selection would be to the first row.I could clear this problem with the 'NavigateTo' property, but , the vertical scroll bar is still at the same position as initially. How can i program the vertical scroll bar to move to row thats required. A code sample is more than appreciated. Thanks If you are bound to a bindingsource you can set its postion to the row number.  Otherwise you can use the currency manager to set the position   Dim cm As CurrencyManager = CType ( Me .BindingContext(DataGridView1.DataSource), CurrencyManager) cm.Posi ...Show All

• SharePoint Products and Technologies Duplicate Submissions occur if refresh button is clicked

  My code has a custom webpart that submits to the content database. However, if the user manually refreshes the page after the submit button has been clicked but before the pages postbacks a duplicate entry is created. Any ideas on how to resolve this I am using Portal 2003. Any help would be greatly appreciated. This is a regular problem with any html form (nothing to do with sharepoint or .net as it were). One of the things you could try is redirect the user to another page (or even to the same page) using the Page.Response.Redirect method after you save the page. This will *break* the connection to the last post. ...Show All

• SQL Server Controlling outbound IP address on a SQL Cluster

  Hello, Is there any way to specify which IP address is used when executing a SQL Job. We recently found that Jobs starting from our cluster (Windows 2003 SQL 2000 SP 4 in a Active / Passive configuration) use the IP address from the local node rather then the virtual IP address tied to the SQL cluster. Jobs executing from the remote SQL server are running. The use of the local address has caused a failure at the firewall.

• SQL Server One detail line per page not working

  Hi all. This appears to be an excellent forum, so I thought I'd post my question here. After searching for similar problems, I was not able to find any that worked for me. I suspect my issue is one of how I'm approaching the report. I have a report that has many tables in it, all apply to each detail line. It looks kinda like, say, an invoice - where you have different parts of the report with different formating needs, etc. When my datasource returns a single value, all is well. When my datasource returns multiple values, I get the pages schmunged (sorry about the techy-terms :-) ) together. What I'm trying for is: Report Title Table1:Line1 Table2:Line1 Table2:Line2 etc. --- page break --- Report Title Table1:Li ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XBOX >10k sprites per frame !

  Just had to test the gfx power with some simple sprites. Printing 48x48 sprites, ideal size for tile map based games it cranked out over 10,000 sprites at just over 60fps Obviously size, scaling, rotation all has a significant impact on speed but nice to know ! I noticed that when the framerate was fixed it didn't matter how many sprites I displayed it always ran at 60fps. How does it do that Does the gfx card abort what its doing when the next frame is ready You may be able to micro-optimize that by inlining the Rectangle and Vector2 construction. Instead of new Rectangle(0, 0, 48, 48), use: Rectangle r = new Rectangle(); r.Width = 48; r.Height = 48; The CLR handles default const ...Show All
