• Visual Basic DeviceIOControl and SCSI_PASS_THROUGH_DIRECT

  Hi, I'm trying to get data from a SCSI Inquiry command in VB. I'm using DeviceIOControl with SCSI_PASS_THROUGH_DIRECT - the call goes through OK and DeviceIOControl returns 0, but I can't seem to get the expected data back - retBytes just contains 7 bytes of seemingly (but probably not) random data: (40, 4, 20, 0 , 40, 4, 20). Changing scsi.dataIn to 0 gets me 255 bytes of data, but not the data I should be getting. Any help would be greatly appreciated. Here's what I'm doing. offset as Byte is ignored for now, and fileHandle is a valid handle to \\.\F:. Private Function getVPDPage(ByVal offset As Byte, ByVal fileHandle As Long) As Byte() Dim status As Long Dim dIn As IntPtr = Marshal.AllocHGlobal(255) Dim dOut As IntPtr = Ma ...Show All

• SQL Server System Stored Procedures do not execute

  I tried this morning to check some of the system stored procedures and ran into trouble. Only four of them executed: sp_alterdiagram , sp_creatediagram , sp_dropdiagram and sp_helpdiagramdefinition . I could not check all the rest, I did it selectively. The typical error message was: Invalid object on RETURN statement. Some had syntactical errors. sp_ActiveDirectory_Obj Invalid object name 'sys.sp_ActiveDirectory_SCP' Line 171 sp_ActiveDirectory_SCP Invalid object name 'sys.sp_ActiveDirectory_SCP' Line 171 sp_ActiveDirectory_Start Invalid object name 'sys.sp_ActiveDirectory_Start' Line 19 Invalid object name 'sys.sp_add_agent_parameter' Line 60 Invalid object name 'sys.sp_add_agent_profile' Line 123 Invalid object name 'sys ...Show All

• SQL Server Maintenance Plan Question

  Hi There I am not sure which forum would eb the right place for a Maintenance plan question, so i am just posting it here. I have noticed that the maintenance plans i have created are not dynamic, by that i mean that for each step, integrity check, backup etc, i have always selected the option all user databases. However it seems that when new user databases are created these are not part of the maintenance plan. Is this correct, do i have to create a new maintenance plan or go back and reconfigure the exisiting one evertime a new user database is created Or am i mising something here P.S i gatehr this from looking at the TSQL from the Maintenance plan afetr creating new databases i see the TSQL still only references the databa ...Show All

• Software Development for Windows Vista Graph Works in GraphEdit but not in Code

  I wrote a DVD player application and built the graph manually (didn't use DVDGraphBuilder and its auto graph building feature, just a normal GraphBuilder with manually connected filters). I added the graph created at runtime to the ROT (Runtime Object Table) and then did "Connect to Remote Graph" in graph edit, thereby loading the graph from my code into graph edit. If I play this graph in graph edit, it works perfectly. But in my program the first screen shows up for about 1 second and then it goes white and then the dvd plays with no video, only audio (with the ActiveMovie window continually filled a white screen). I can't figure out why the graph will not keep on rendering the video when running the code, since the exact same graph (sam ...Show All

• SharePoint Products and Technologies Adding "Person Column" to a list

  I may be barking up the wrong tree but thought I would throw it out there. Using MOSS and the BDC, we have the capability to add Business Data as columns in a list. How would I go about creating a "People" type in my BDC that pulls the data from the user profiles in MOSS What I would like to do is have a drop down or search screen for selecting a person from the profile store instead of keying the information into a contact list and then having the information be out of date , etc... It would be much easier to just allow them to select a person and pull the data from there. They would also get the "Presense" pawn next the persons name etc.. which would be very useful. Does this sound possible Has anyone done th ...Show All

• Smart Device Development Scanning SDK in Compact Framework Issue

  Hi all, I have found an issue with the Imaging/Scanning SDK that the Compact Framework uses and would like to report this issue with Microsoft. How exactly do I go about do this Thanks Tryst The issue is that when I make use of the Symbol scanning (or imaging) API on the MC50 device in my application, and the device memory goes lower than around 7.50 MB (its got the memory slider indicating free program and storage memory on the MC50) I get a SCAN_ENABLE exception. When I get this, it means the scanner is screwed (disabled) until a soft-reset is performed on the device. I guess it doesn't free up all the resources when gets the first error.
