• SQL Server SQL Server 2005 - Scheduled jobs stop working

• .NET Development Javascript "Access is denied" error with a form in an iframe

  Hello there, I have a form in an iframe, and the iframe is sticked on another document (.asp) which has some forms on it too. I'm also using AJAX for ASP.NET, but I think that hasn't got to do with it. Everytime I click in a textbox, I'm getting the error message "Access is denied" (javascript error). It has something to do with the forms on the parent page. Is this problem familiar I hope someone has a solution for my problem. With kind regards, Gideon It has certainly something to do with ASP.NET AJAX 1.0.

• Windows Forms How to set and check Low Battery Alarm level and settings through software?

  I am trying to develop a battery test. One part of it will set the low battery alarm to 75% and verify that it triggered, then reset it to the original value. I have looked in many places and cannot seem to find it. However, I know windows is doing this somehow through their Power Options GUI in Control Panel. Anyone care to shed some light on this issue There is ULONG BatteryLevel, which is the percentage level for the alert. BatteryLevel is inside struct SYSTEM_POWER_LEVEL. SystemPowerLevel[0] is for critical battery and [1] is for Low battery alarm. SYSTEM_POWER_LEVEL is inside GLOBAL_USER_POWER_POLICY, which is inside GLOBAL_POWER_POLICY. Use GetCurrentPowerPolicies to read current values. U ...Show All

  Hi Xnacers: I need to create a mesh the from scratch, not load a predefined mesh from an x file using the content manager.

• Visual Studio Express Editions if statement

  Hi, Can you please let me know what is wrong with the following if statement I believe the following values should make the statement to show the messagebox. Do you agree Thanks intPosHomeUS= -1 intPosHostUS= 7 intPosHomeUK= 7 intPosHostUK= -1 if (!(intPosHomeUS > 0 && intPosHomeUK > 0) || (intPosHomeUK > 0 && intPosHostUS > 0)) { //show messagebox... } else { //print report... } I agree. And it does. Be sure to post your exact code. !(intPosHomeUS > 0 && intPosHomeUK > 0) == !(-1 > 0 && -1 > 0) == !(false && false) == !(false) = true Note that your statement is equivalent to: bool term = intPosHomeUS > 0 && intPosHomeUK > ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Speech SDK is a recommended XNA download? :D

  Speech SDK works with XNA :P There is NO connection between the Speech SDK and XNA. I'm not sure which ULR people were looking at to see a related resources section that connected the two (I just checked out the  speech API downloa d and cannot see any reference to XNA). So I suspect that any link was accidental and may be to do with th way the MSDN site handles those 'related resources' sections. The only 'sound' technology included in XNA Framwork is XACT, which has no microphone support (XInput returns DirectSound referencs for the headset functions and no DirectSound in XNA). Since Speech SDK is native code it also wouldn't be possible to use on the xbox anyway since managed -> native interop is not supported there. ...Show All

• SQL Server Problem with ConditionAction SqlLogin

  I have a problem based on some security settings that I hope any of you can explain for me. I have made a ConditionalAction and specified a SqlLogin (and SqlUser). It compiles, the service gets started but every time the conditional action gets fired, an error message occurs in my event log. The error message says something like "the principal SqlLogin does not have access to myDatabase under the current security context". The SqlLogin do have access, I've giving all possible permissions to make sure it is not a permissions problem. And when I login to Management Studio using my SqlLogin, I get to run the very same query that fails when executed from within NS, with no errors. Any ideas of how I can give my ...Show All
