• Visual Studio Express Editions Prevent Unbound DataGridView From Adding New Rows -- and more

  I've been in VB6 for a LONG time and can do most anything I want with it but I'm just getting started in VB 2005 Express. I want to rewrite my gradebook program using an unbound grid control (thinking maybe DataGridView). When I edit a cell in the last row of my grid, the grid wants to add another row on the bottom. How can I stop this ============================================= Another option I have is to use a 3rd party control like FlexCell. Adding extra components in VB6 was easy but how do I get a new control (beyond the ones included in VB2005) like FlexCell in my VB2005 project I figured out that I have to add a reference in the Project Properties tab, but my FlexCell does not appear in the toolbox. I was able to copy a flexgrid ...Show All

• Visual Studio Express Editions Having difficulties with a timer and an if-then statement

  Hi, been spending a lot of time on timers and they finally make some sense now. In my program there's this button. When it's clicked a shell command is executed and right after that the program needs to wait until some folder is created (by an external process). It enabled the timer and the timer2_tick sub is executed... But the other process keeps running as well. I need to figure out how to pause everything except the timer that checks every 5 secs if a folder exists until the folder actually exists... Many thanks!

• Visual C# Writing a 16-bit grayscale image

  I have a byte array containing pixel values for a 16bpp grayscale image. I need a solution for converting said array to a bitmap image. So far I've come up with this: internal static Image imageFromArray(byte[] array) { const int WIDTH = 1472; int height = (array.Length) / WIDTH / 2; Bitmap bitmap = new Bitmap(1472, height, PixelFormat.Format16bppGrayScale); for (int x = 0; x < height; x++) for (int y = 0; y < WIDTH; y++) bitmap.SetPixel(x, y, (Color)array[(y * 1472 + x) * 2]); Image image = bitmap; return image; } But there is an error because I can't cast the byte as a color. So my question is, how do I actually translate my pixel data from the byte[] to the bitmap Is there a better way to do t ...Show All

• SQL Server Prolonged execution for table UPDATE statement - not sure it finishes

  I am cleaning up a large database table that has Date keys instead of real DateTimes. To do this, I am running the following query... UPDATE MQIC.DBO.OBSERVATION_F SET MQIC.DBO.OBSERVATION_F.OBS_DATE = MQIC.DBO.DATE_D.ACTUAL_DATE FROM MQIC.DBO.OBSERVATION_F INNER JOIN MQIC.DBO.DATE_D ON MQIC.DBO.OBSERVATION_F.DATE_KEY = MQIC.DBO.DATE_D.DATE_KEY where Actual_Date is what is being stored, and the Date_Key is to be dropped. The particulars are this - Date_D table - 92,000 rows - 40 MB Observation_F - 20,000,000 rows - 3.2 GB This is being run on a remotedly hosted rack server with an AMD processor, 1 GB RAM, 60 GB harddisk space, 20 GB used.

• Visual Studio Permissions table renders without style

  When specifying a <permission /> in doc, the set of required permissions renders in the end documentation in a table, but it doesn't have the same styling as other tables (like the exceptions table), making it inconsistent and sort of hard to read. This happens in the September 2006 CTP refresh. Looks like some styles are missing in Prototype transforms. We will investigate and will provide a fix. Anand... ...Show All

• Software Development for Windows Vista worked but now black screen on load screen ( RC1 Build 5600 )

  Here are the facts worked for a couple days, no major problems, worked pretty nicely compared to beta 2 installed these two programs on my last time working on it before it crashed - 3ds Max 7 - ITunes update have plenty of room for Vista, and its on its own hard drive when i booted recently the screen is just blank, but the build info in the bottom right hand corner is there, and is correct. I noticed a slight swaying in the color of the blank screen, but very little, making me think there is something wrong with the load screen. the blank screen isnt the login screen but the little animation before the login screen, where the windows symbol does a glow thing.

  I have custom Activities that i had created, one of them is an image picker, that uses an image resource manager, which stores all selected images as binaries How do i go about persisting the manager along with the activity: ImagePicker into a xoml file Thanks One possible approach is to store only image names in the manager and store the actual images in a seperate resource file.
