Thr type hbitmap in the labview

Hello

I had a Dll located in the internet.

Now, I want to use "Call library function node" to get the data of this DLL.

Unfortunately, I don't, t know how to set the "HBITMAP" without knowing the type of law in labview.

the code of the DLL: extern "C" __declspec (dllimport) bool __stdcall DataMatrixDecodeBitmap (HBITMAP hImage, char * pResult, int * pSize, int nTimeOut);

Is any body knows the right type of HBITMAP in the labview? Table? or labview can, t take charge kind of guy.

Any suggestions would be much appreciated.

Thank you

Hello

try looking in the header, what is this type of data. It can be a custom structure defined in this file. If so, thread a cluster with the same elements that are in the structure.

EDIT: found on google

--------------

Although Windows handles are under 32-bit Windows for most of the pointers to memory
It would be a bad idea to try to directly access these data. Windows handles are
supposed to be types of opaque data whose internal structure is only known for Windows
and more specific to Windows versions that are similar or better than the one that created it.

The Windows API gives you (almost) all the specific access features
information inside a handful. HBITMAP would need to access the API
function GetDIBits(). This function works with a HDC device context handle you
probably need to get your capture card interface. This is necessary to convert
device-dependent in a HBITMAP independent unit information
(the GetDIBits DI) information in the settings that you want to receive.

-----------------

So, here's an I32 or I64, depending on your system. It is a pointer to a memory space.

And here is a previous discussion: Forum OR

  • Any camera regardless of the interface is available for use with the LabView interface.

    Hello

    I intend to go for some CMOS camera,

    but I have a huge doubt before buying, the camera of menttioned above is not anywhere in this list. Nor can I see any type being supported USB device.

    The question is

    1. is a camera regardless of the interface is available for use with the LabView interface?
    2. Can I build a VI to communicate with any device image and recording of camera and take the data?

    Any kind of help or advice is greatly appreciated... I have to buy a CMOS camera and begin to run.

    Thank you...

    Hello Virginia,.

    I am pleased that this information has been useful, one thing I wanted to mention is that USB 3.0 has its own standard USB 3.0 Vision which is currently not supported. If this camera is also Direct Show compatible then you will be able to acquire an image using IMAQdx and manipulate all the attributes that are published to the API Live Show.

    I hope that USB 3.0 Vision will be supported in the near future, and we tentatively announced for this standard of communication for the August 2013 Vision Acquisition Softwareupdate.

    See you soon,.

  • Download the Version of the LabVIEW project

    Lets say I have a random LabVIEW file.  Can I use the Get file Type.vi in the VI.lib to understand what the file type.  It could be an Instrument, control, project, library, XControl or one bunch of others.  If it is a VI I can use the Version of VI get call node to find what version of LabVIEW, it was made with.  If it is a library I can use the Version of LabVIEW in the Library.Get file for the version, or if it's a project I can use the LabVIEW Version of the Project.Get file.

    What I find strange, is if I have a VI in 2013, and I run the node invoke for the version of LabVIEW reading but my development environment is 2011, he will say that the VI was marked by 2013.  But if I have a project saved in 2013 and use the node invoke for the version, and my development computer is 2011, I get an error indicating that the file version is later than the common mistake of version LabVIEW 1125.

    Is this a bug?  I mean I read the project file as text and analyzed with an XML parser version.  So why this function choke and die trying to read the most recent versions of file, but a VI and the library can be read without problem?

    There was a bug in the "Project.Get LabVIEW Version file" method. LabVIEW has been set in 2012.

  • Causing problems of custom data type to deploy the shared target RT variable

    I seem to have some difficulty in using a shared variable published network created from a customized data type when it is deployed as an executable on a target of cRIO RT.  I'll start by describing why I think that this is the rub.  I created my RT VI in the LabVIEW (LV 2012) development environment and everything works fine.  This VI is quite simple, because these were quickly devolved into an exercise in debugging.  The RT VI begins by simply flashing the LED to a couple of times and then starts a loop simple acquisition to read some values out of the material using the analytical engine (while still flashing the LED of the user).  After reading the material, the values are grouped in a cluster and written in a shared variable published to the network defined by a custom control type def.  The custom control contains five floats double precision.  If it's important, the RT cRIO system hosts the shared variable in this case.

    So I have that deploy in the development environment, and everything works fine.  The LED flashes merrily along, telling me that the program runs correctly.  Running a VI host who reads the shared network has published variable gives the desired result.  Everything is good.

    Now, I want the cRIO system to run this simple program by itself at startup.  I build, set it as start VI, deploy it, and then restart the cRIO target.  The LED never flashing... the VI doesn't seem to work.  I'll spare you the major part of the work of debugging and access to the end.  I basically "diagram Disabled" various sections of the code up to the VI began to run correctly in an executable file.  I kept reducing the size of the disabled code until something has been disabled: the writing in the shared variable for the custom data type.

    So, I guess my question is this: are custom data types defined by type def would be personalized orders authorized executables to RT?  I read through the cRIO Developers Guide, my book of development in real time course of NOR and the white paper using shared Variables and I see nothing that forbids it.  I know that there are things not allowed in the executable files that are allowed in the development environment (property nodes façade, dialogue live, operating system specific calls, etc.), but no mention of the shared variable type custom data.  Any ideas as to why my VI is running in the development environment, but does not update unless I have delete the entry on the published network variable shared?

    Thank you in advance for your help!

    You must disconnect the data types of variables and then recompile. You can find it useful to keep on disk, a copy of the original lvlib.

    Don't know if this is a bug or not. It was suggested by someone in the forum that putting the ctl files in the right position (the disk? in the draft?) would allow the rtexe start; I did a quick check and it didn't work then I dropped the tests more far.

  • How to open the labview with function of Labview program to stop smoking inside?

    Hi any idea how to open the labview with the Labview function program to stop smoking inside?

    I forgot to add and define the condition of the type for this program.

    If the program is an application, she closed immediately.

    If it is still the work of labview, it will go directly to editing without closing the program.

    I so need to retrieve, open it and make some changes.

    Clement

    Place the VI in a project and open it from there, then it should not autorun. App.kind application property allows you to decide whether to close or not.

  • Migrate from the Labview inspection does not have to acquire the image

    I migrated my inspection of Vision helps with Labview 8.6 and the sad program he managed. But I have Labview 8.6 I got a long error list containing different items IVB IMAQdx (Exec (for RT.vi), management resources (for RT.vi), etc...). Number of items had the error messages "definition not found xxx:Type or contains errors", "xxx: Subvi is missing ' and ' xxx: Subvi is not executable. Inspections in Vision Builder works very well, and the Vision Builder to Labview migration also works very well I I choose a simulated acquisition. What is the problem and how a slove it?

    I have LabView 8.6, Vision Builder 3.6.

    / Johnny

    The stage of image acquisition depends on a driver whose API is not installed in your folder of LabVIEW. Reinstall the software of Acquisition of Vision and do not forget to install the LabVIEW 8.6 support.

    In addition, Data Logging and Image Logging steps require the internet Toolbox. Look in the "Migration of LabVIEW" section of the online help for a list of the drivers/toolkits, you must install when using hardware related as follows.

    I hope this helps.

  • 27 "+ monitor of type C in the United Kingdom?"

    Afternoon,

    Recently I've been looking for a more tidy installation my Mac Book Pro 15 "(rétine fin 2013)." I have the henge horizontal dock now, but my laptop constantly get hot (fan will nut) and when I run the mac and 2 external performance of the screens are terrible compared to the execution of installation even without the docking station. I don't know why.

    In any case, I was looking around and I see there is such a thing as a monitor that you can run with your MAC that acts as a host/HUB for the Mac Dock. And all via a single cable wired to the mac? Display port to a port of Type C 3.1 at the back of the monitor. So far I have found that a LG and acer have all two monitors type c. I chose is called Acer H277HU. Now here's the weird part. I can't find this exact model, which comes with a connection of type-c at the back, to the United Kingdom? In fact I can't find any available for sale in the United Kingdom the monitors who says anything about a port of type c in their specifications. This particular mode has a UK version but it does not have a port of type-c at the back of the monitor in the images or mentions a connection of type c in the specifications?

    Here, I'm a bit confused. These are simply not an option in the United Kingdom or something? I hope someone can help us with that.

    Why a port of type C, your Mac is not, is - this according to the Henge?

  • with AutoComplete on, I can no longer type "https" as the beginning of a URL

    I have used AutoComplete in previous versions of Firefox and I was able to type "https" at the beginning of a URL, but now since I did not register domains starting with 'h', AutoComplete imediatley changes the 'h' to a 'p', makes it impossible for me to type "https". I understand I can hit 'esc' after typing each letter, but it's crazy.

    I guess that Firefox now ignores the part bookmarks Protocol and that is why what is happening.

    You can set the pref browser.urlbar.trimURLs false on the topic: config page to see the http: Protocol.

    Try Firefox SafeMode to see how it works there.

    A way of solving problems, which disables most of the modules.

    (If you use it, switch to the default theme).

    • You can open the Firefox 4, 5, 6, 7 SafeMode pressing the SHIFT key when you use the desktop Firefox or shortcut in the start menu.
    • Or use the Help menu option, click restart with the disabled... modules while Firefox is running.

    Do not choose anything at the moment, just use 'continue in safe mode.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before using the shortcut of Firefox (without the Shift key) to open it again.

    If it's good in Firefox Safe mode, your problem is probably caused by an extension, and you need to understand that one.

  • After downloading Firefox 4, when I type something in the address bar that he used to go directly to the site, now it goes to google. How can I change this back?

    For example: I could type 'facebook' in the address bar and it would automatically take me to facebook.com now he takes me to google.com and shows me the search results. I want that Firefox take me directly to the page as before I installed Firefox 4.

    I hate this new feature. Here's how to disable if:

    Come on in "subject: config" in the URL
    type in 'keyword' in the filter bar
    Locate the property "keyword.enabled.
    Double click on it to make sure that the value is set to FALSE

    eventually Firefox will take you directly to a Web site when you type in, instead of doing a search for it. Know that, if the word that you type does not lead to a Web site live while you're not going nowhere.

    To counter that, for example, if you want to go to Facebook.com , but don't want to change anything in the settings of Firefox, hold down the 'Ctrl' on Windows when you enter a URL. Which will automatically add the ".com" at the end of any word you typed in. Note that this adds only the ".com" and will not automatically recognize ".edu", ".gov", etc.
