Are you sure that's the right header file?  It's named differently than the source code file.

LV is indicating that the functions defined in the source code file do not match those from the header file, so it's having trouble interpreting them.

Many thanks for your answer, Could you provide me by the example for compatible header file with labview may be I go to write new header file for the dll file.

Could I send for you the header file +Dll file to check it for me please

Dear an.sh,

Thank you for your post to the forums.

I wanted to find out some more information in regards to what it is you are trying.

What type of .dll are you trying to bring into LabVIEW? Was it written in a text based programming language such as ANSI C/C++? 

Where did you obtain the header file shown in the image? As mentioned above, the header file is different to the source code.

I can see you have tried to use the Import Shared Library Wizard. 

For further information, take a look at the following links:

- Calling .NET Assemblies From LabVIEW

- Calling C/C++ DLLs Containing Simple and Complex Datatypes from LabVIEW

Let me know how you get on.

I tried to building my VI by MoveBlock I found

all function in side Dll return  Boolean type as I shown below in pic and there are no Boolean in Labview type as shown in pic any one have any idea about that

I think in that case you could use numeric.  I don't remember exactly what options you have for a numeric return type...

Hi an.sh,

I hope you are well.

Have you managed to sort out the data type conflict you were seeing?

Do you need further assistance? Do you have any further queries?

Kind Regards,
