• Visual Basic Controlling a Timer with an External Input

  Hello, im writing a vb program that is a graphical user interface for a robot. When the robot starts up it sends a command to PC telling the gui to start a timer showing how long the robot has been running. The only problem is that the timer never enables, It goes through the decision statement and says it should execute, but never does ( i put break points in after the hthe line of code where I enable the timer, and it says the timer should be enabled, I also put a set of break points in the timer ISR, but those are never tripped). Basicaly what my problem boils down to is there anyway to set off a timer from an external input. ...Show All

• Windows Forms Rogue browser control - AxSHDocVw in Windows Forms App

  Hi, I seem to be getting some crazy behaviour from the SHDocVW internet browser control in my app - whenever i change the visibility or location of the parent form, the browser control seems to pop out and sit in the top left hand corner of the screen - you only notice it if you make the form visible again. Also, if you load a different& ...Show All

• .NET Development Help to get a solid UpdateCommand for DataSet

  I have a small amount of experience working with writing UpdateCommands for SQL changes, but none of them have involved working with datasets - just passing variables to a datasource parameters in Stored Procedures and having WHERE clauses update them. However, I'm now working with DataSets, and I'm stumped on how to write changes made to the Dataset to the database, and was hoping someone could give me some demo code, or point me in the right direction - "Write Dataset Changes" didn't give me a lot of help on Google. In the past, I've had this ADO project connected to an MSAccess database, which apparently handles updates and del ...Show All

• SQL Server error creating named calculation

  I'm new to MS DM and am using the book "Data Mining with SQL Server 2005" by Wiley. On page 95 I try to follow the procedure for creating a named calculation, but I get this error: IErrorInfo.GetDescription failed with E_FAIL(0x80004005). Any ideas what's wrong Jamie, Thanks for the help. I'm using the Access MovieClick DB that I downloaded from the Wiley web site. Also, I can create other named calculations just fine, such as adding two columns, or taking the log of one. It just seems to be the CASE examples that give me the error. ...Show All

• Visual FoxPro Cancel Button Does not work--A known bug?

  I have no idea if it is a known bug. The important fact for me is that it is a bug. It occurs in _VFP.StartMode = 4 as well as in interactive session (_VFP.StartMode = 0). It caused me to lose numerous error records before I realized what was going on. In exe environment when one error follows another there is no way to quit because the Cancel button does not do what it is supposed to be doing. You crush the system and no records are saved of course. Anyway, this is a stamp of one of the session errors: An error has occured "feature is not available" (1001) ADDPROPTOFORM 2998 ....

• Visual Basic Nullable Types In VB 2005

  In one of the MSDN articles on the C# enhancements for the 2005 version, there is a mention of Nullable Types (see http://msdn.microsoft.com/vcsharp/2005/overview/language/nullabletypes/). Will Nullable Types be also available in VB 2005 I hope so, as Nullable Types is the only language feature that I find compelling enough to make me want to switch. A.K. No the differences don't go beyond syntax. You have the same support in VB, you just have fully write out the name of the Nullable type. ...Show All

• .NET Development WinForms Vs WebForms

  Where can I get the list of pros & cons generally speaking WinForms are Richable but not reachable , on the contrary WebForms are Reachable (but not richable due to performance factors). so the question is : can we have a form that is both richable and reachable at the same time . the answer is simply , yes "Click-Once deployment ". there was an old article about hosting a windows form over IIS , and this would lead to the death of browsers we know today . http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnadvnet/html/vbnet10142001.asp so if we can really work this way by hosting winforms over IIS , why would we nee ...Show All

• Visual C++ Cannot open precompiled header file: 'Debug\test4.pch': No such file or directory

  I want to say that's why the error information: Cannot open precompiled header file: 'Debug\test4.pch': No such file or directory. Hi! I saw this error when I tried to compile a project that I had created clicking on "Empty project". But if you create a project clicking on "Win32 Console Application" the compiler shouldn't show this error. You can also try to go in "Project -> Preperties -> C/C++ -> Precompiled Headers" and select "Not using pre-compiled headers" in the combo-box "Create/Use precompiled header". ...Show All

• .NET Development Network access for a web app

  Hi all, I have a web app that I am developing that retrieves a list of the computers on the network and then displays their date of last reboot. It works fine while on my computer in the dev environment, however if I try to use it from another computer I only get my computer's info. After some work I have found that when I call If (PerformanceCounterCategory.Exists("System", Machine)) I get an unauthorized access issue. I’ve added [assembly: PermissionSetAttribute(SecurityAction.RequestOptional, Name = "LocalIntranet")] But I only get a login box now which is just horrible. I currently have the web app set to Imperson ...Show All

• SQL Server Did SP1 fix Query Optimizer issues w/ Partitioned tables?

  Hi there, We've implemented a partitioned table to a large table within our EDW. However, we'd discovered that the Query Optimizer was not able to understand parameterized queries. It basically was scanning all the partitions even though a parameter was passed defining the partition to use. Consequently, the queries need to hard code parameter values! Does anyone know if SP1 addressed this problem Thanks -Walter Are you certain that it's scanning all of the partitions   You might want to look at the Actual Row Count in the execution plan to find ou ...Show All
