• Disable the button "Close" command through LabVIEW prompt by using the Win32 API

  Hi all

  I'm trying to disable the close button of a third party console application which I invoke with LabVIEW. I tried to use GetSystemMenu() and DeleteSystemMenu() user32.dll, but somewhere I'm doing it wrong.

  Can anyone suggest a solution to this?

  Thank you!

  You have the window handle?  Hand, I don't know how to remove it, but here is a code c# I used to gray on the close button the window in another project:

  [DllImport ("user32.dll")]
  private static extern IntPtr GetSystemMenu (IntPtr hWnd, bool bRevert);
  [DllImport ("user32.dll")]
  private static extern bool EnableMenuItem (IntPtr hMenu, uint uIDEnableItem,
  uint uEnable);

  private const Int32 SC_CLOSE is 0xF060;.
  private const UInt32 MF_BYCOMMAND = 0 x 00000000;
  private const UInt32 MF_ENABLED = 0 x 00000000;
  private const UInt32 MF_GRAYED = 0 x 00000001;
  private const UInt32 MF_DISABLED = 0 x 00000002;
  private void EnableClose (Boolean enable)
  {
  IntPtr pSysMenu = GetSystemMenu (Handle, false);
  If (pSysMenu! = null)
  {
  EnableMenuItem (pSysMenu, SC_CLOSE, MF_BYCOMMAND |) (activate? MF_ENABLED: MF_DISABLED));
  }
  }

  It was easy enough to convert more than once I had the handle (it's a library, I picked up somewhere).

  I hope this helps.

• Error of the 2 Win32 APIs, impossible to find ShellExecuteExW form AgWorkspace.shellExecute

  I get this error: error in the 2 Win32 APIs, impossible to find ShellExecuteExW form AgWorkspace.shellExecute

  When you run my gout, that worked a few days ago.

  Have been install and reboot a new install of WIN 10 and LR, PS CC
  Hope someone can help me.

  JohnRellis,

  interesting.  When you run DNG... 11 seems to be my limit... even in LR, CC PS updated to the current.

  I just ran "Processor of Image" in PS CC... and it seems that it can last forever (done properly).
  BUT, Yes... the problem... and time killer is, you must import it in (I do a SYNC)... and then manually regroup with the DSP on the top.

  Wish Adobe would update image processor to... Auto Import and group with the DSP on the top of the stack.

  Thank you John for all the help.

• Failed to export.  Receive a notice of error 2 Win32 API whenever I try to export.  Says it can't locate the files.  Huh?

  Ok

  I get a system error whenever I try to export. "An internal error has occurred: error in Win32 API 2 (the system cannot find the specified file) when the Shell Execute ExW of the AgWorkspace.shellExecute."

• To change a value in the array of the HR user API hooks API - can I use?

  I am trying to initialize a descriptive flexfield on per_all_people_f. I tried initially to do initialization using a database trigger "before inserting line" directly on the table. per_all_people_f seems to work perfectly in the form of people (PERWSHRG), but doesn't seem to work constantly when a new employee is entered into a model as employees enter (PERWSQHM).
  
  Does anyone know if you can use a hook of user API to initialize a value on an API tables o is the insertion? For example, could put a user hook "before the process' on the 'Create_ employee' API to change the value of a descriptive flexfield?
  
  Other good ideas?
  
  Currently I have a concurrent application which runs once every 30 minutes by default the descriptive flexfield. The delay is causing issues.

  Yes, API user hooks are not good to make updates. Has a database trigger that updates the person table in an API call which also updates the person table is not advisable and development Oracle would not encourage him: the person API is complex and could (even if it is not now) substitute, regardless of your prior release don't (API retrieves first the old values which is in front of your trigger fire and uses as the basis for updating).

  Would you rather write a simple simultaneous program that covers everyone who did not have this value set and default it? In this way there is no risk of your substance interfering with the standard Oracle stuff (and vice versa).

• How to fix Firefox 31, 0-1 crashing on the Audio-Api - for example on quizlet.

  Dear Firefox team,

  Since yesterday (after the updates), Firefox hangs when it tries to play a sound. I think because of the Audio Api? It crashes on Google-Mail and Quizlet.

  For quizlet, I found a site where they describe how their sound: http://quizlet.com/help/how-does-audio-work-on-quizlet

  When I opened the file audio-test firefox crashes instantly without an errormessage. Here you get the example file: http://a.s.quizlet.com/en.mp3?v=5 & b = SWYgeW91IGNhbiBoZWFyIHRoaXMsIGF1ZGlvIGlzIG5vdCBiZWluZyBibG9ja2VkLg & s = LAhrMA-0

  Can I do something about it? Its really hard for me to understand why it crashes.

  Hey again once, unfortunately I can't reproduce the problem on a windows pc and the console log is not very descriptive (at least for my level of knowledge).

  If you can reproduce the same breaks down while you use firefox in safe mode, I would recommend filing a bug to the bugzilla.mozilla.org of this regression, so that developers have a closer look.

• x 64 (64-bit) bug in the C API

  I try to get the C API of 64-bit running.  I have the 32-bit running API, and it is not working properly.  It seems that no API call in the 64-bit environment, which returns more than a single data type replaces a box of memory it does not.

  I work in VB.NET and enveloping with a marshaling calls.  The simplest example of a call that is not working properly is querying the active channels on the scope:

  C header:

  niVB_Status NIVB_DECL (niVB_MSO_QueryEnabledAnalogChannels)
  niVB_MSO_InstrumentHandle instrumentHandle,
  char * channels.
  size_t channelsSize,
  size_t * channelsSizeOut);

  There are several different ways to encode a managed, unmanaged for this translation.  First is to use an allocation to build a pointer on a buffer zone:

  Pointer = Marshal.AllocHGlobal (MAX_CSTRING_LENGTH)

  Then, the declaration looks like this:

  _
  Public Shared Function niVB_MSO_QueryEnabledAnalogChannels_64 (ByVal instrumentHandle As Integer, ByVal channel As Integer, ByVal channelsSize As UInteger, ByRef channelsSizeOut As UInteger) as niVB_Status
  End Function

  When the call is made, the call to channelsSizeOut returns 23 characters (which is correct).  Channels IntPtr is however cancelled (this should never happen, he suggests that the battery is getting damaged.)  If I put a very wide range locally around the pointer, sometimes it is not damaged.

  Or you can call the function by using a call to stringbuilder.  Basically, it replaces the IntPtr parameter with a string generator using marshaling for a pointer:

  Dim bufChannels As New StringBuilder (MAX_CSTRING_LENGTH)

  then the call looks like this:

  _
  Public Shared Function niVB_MSO_QueryEnabledAnalogChannels_64 (ByVal instrumentHandle As IntPtr, ByVal channel As StringBuilder, ByVal channelsSize As UInteger, ByRef channelsSizeOut As UInteger) as niVB_Status
  End Function

  Yet once, calling this function causes the stringbuilder class being together (Nothing), which is essentially showing that stack space where is the pointer to the StringBuilder is getting damaged.

  It is important to note that this code works perfectly with the 32-bit version of the DLL (with a programming construct).

  I don't think it's a bug in the C API; I can do the following for both x 86 and x 64 without triggering of MSVC stack Canaries. (Note that for brevity, it does no checking error in this code snippet.)

  #include
  #include
  #include ' nivirtualbench/nivirtualbench.h '.

  int main (int argc, char * argv)

  {

  niVB_LibraryHandle libHandle = NULL;

  niVB_MSO_InstrumentHandle msoHandle = NULL;

  size_t channelsSizeOut = 0;

  char * enabledChannels = NULL;

  niVB_Initialize (NIVB_LIBRARY_VERSION & libHandle);

  niVB_MSO_Initialize (libHandle, "brandonbench", false, & msoHandle);

  niVB_MSO_QueryEnabledAnalogChannels (msoHandle, NULL, 0, & channelsSizeOut);

  enabledChannels = (char *) calloc (channelsSizeOut, sizeof;

  niVB_MSO_QueryEnabledAnalogChannels (msoHandle, enabledChannels, channelsSizeOut, & channelsSizeOut);

  printf ("permit to channels: %s\n", enabledChannels);

  Free (enabledChannels);

  niVB_MSO_Close (msoHandle);

  niVB_Finalize (libHandle);

  }

  I suspect that the problem is in your marshaling. Size_t parameters are probably better represented using System.UIntPtr and not the type UInteger; size_t is 32-bit on 32-bit platform and 64 bits on 64-bit platforms, but UIntegers are 32-bit at a time. Try to write channelsSizeOut, it's probably what is triggering the corruption of the stack.

• W530 with Windows 7: the GetSystemMetrics API functions do not correct result

  Hello

  I recently updated my external monitor for Samsung S27A850D best resolution 2560 x 1440. After some effort, I finally managed to get this resolution, and, among other things, the section of the display of the control panel correctly shows the resolution. However, when I use the function API GetSystemMetrics with the SM_CXSCREEN and SM_CYSCREEN parameters get values in 1707 and 960, respectively. Does anyone have an explanation for it?

  Kind regards

  Hello

  Thanks a lot for your comment. In fact, I have defined the size to 150%, but I was completely unaware of the mechanism behind it and really didn't know anything about scaling issues.

• Can I synchronize the counters on two different computers in the C API?

  I installed the M-series cards (6254) in several computers. I would like to synchronize the counters for each card.  The best way that I came with to do this was to have the counter on each counter entries read a common external clock signal running at 10 KHz I have would then feed a second signal to each card and trigger the task that runs each counter starts when the second line goes high.

  Following the examples provided with the C API, it was easy to get each card KHz signal and then to match the beginning of the counter that I tried to read

  DAQmxCfgDigEdgeStartTrig (taskHandle, inputLineStr, DAQmx_Val_Rising);

  However, this did not work and gave me the following error:

  DAQmx error: the specified property is not supported by the device or is not applicable to the task.
  
  Property: DAQmx_StartTrig_Type
  
  Task name: task
  State code:-200452
  
  End of the program, press the Enter key to exit
  
  

  I know it's very simple sync the cards within a computer using the RTSI interface, but it is not possible that my cards have to reside in different computers.

  It is even possible to synchronize the counters on computers, and if yes how can I do it with the C API?

  Hi neurostu,

  Arms start triggers are disabled by default, so they do not have a default PFI line.

  You will need to set some properties DAQmx to configure a trigger for start of arms. Try adding between DAQmxCreateCICountEdgesChan() and DAQmxStartTask():

  DAQmxSetArmStartTrigType (taskHandle, DAQmx_Val_DigEdge);

  DAQmxSetDigEdgeArmStartTrigSrc (taskHandle, "/ Dev1/PFI14" ');

  DAQmxSetDigEdgeArmStartTrigEdge (taskHandle, DAQmx_Val_Rising);

  You have the file "help NOR-DAQmx C reference"? It should contain descriptions of the trigger > more > arm Start properties.
