Error building a DLL

I am getting this error while I attempt to build a DLL. I have reinstalled LabVIEW and the drivers twice with no help. Any thoughts would be apprieciated. Thanks.

To whoever gave my response one star: If you have a better answer, why don't you post it instead of hiding behind an anonymous rating? That article directly addresses the user's post. Whether or not it solves the user's problem depends on whether or not it's tried in the first place. Did you take issue with my comment regarding searching?

Error 1 while building a DLL

Hi,
I have programmed some signal processing project libraries in LabVIEW and would like to use them in a VC++ program. When building the DLL under LV 8.0, I get this error 1 message:
Error 1 occurred at ABAPI Dist Define VI Prototype.vi -> ABAPI Dist Verify Proto Defined.vi -> ABAPI Build Shared Lib With Old Proto.vi -> DBEP_Invoke_Build_Engine.vi -> DBUIP_Build_Invoke.vi -> DBUIP_Build_Rule_Editor.vi -> DBUIP_Item_OnDoProperties.vi -> DBUIP_Item_OnDoProperties.vi.ProxyCaller
Possible reason(s):
LabVIEW: An input parameter is invalid.
NI-488: Command requires GPIB Controller to be Controller in Charge.
Any clues?

This happens when you're building an executable? The default build path for executables should be C:\Users\**Username**\builds\**ProjectName**\**ApplicationName**
Often, repairing your install can fix strange problems like this. Just go in like you're going to uninstall LabVIEW, but instead repair it.
Additionally, what do you have as the input to the invoke node you mentioned?

Error Building DLL, LabView 8.2

Hello everybody,
I'm building a
CVI application. I need some functions of LabView (related to time
series analysis), so I'm trying to build DLLs with the .VIs I need. I
followed all the steps necesary and visited all the related topics at
ni.com. I always get the following error:

I'm using: LabView 8.2, LabWindows CVI 8.5, NI-DAQ 8.5, Windows XP (SP2)
Any suggestion is really appreciated.
Maybe another way to use this functions in CVI (I need functions related to spectral estimation, ARMA; MUSIC,...)

Can anyone help me to get rid of this problem?
Thanx & Regards,

srini,
Are you trying to use the dll in LabVIEW and getting the error from LabVIEW? If you are using Measurement Studio there is a seperate discussion forum for those issues. The MSVCRT is a Microsoft Visual C Run Time library. This thread explains it a little better: MSVCRT.dll
If you are trying to create C++ dlls to be used in LabVIEW you may need to create wrappers if you are using certain classes. Here is some more information on calling dlls in LabVIEW An Overview of Accessing DLLs or Shared Libraries from LabVIEW

Error of heads when build the .dll by visual studio 2003

I am trying to call the dll function in labVIEW which build by visual studio 2003.
while I compile the basic program in visual studio 2003,the dll will be built successfully,but if I include heads like or in my program, etc.Compiling has the error of ,so the dll can not be built.
I have trued to look for the solution in NI Discussion Forums,but havent seen the related article about the error of including .
If someone can answer this for me,that will be a great help,and I'll be so appreciate if anyone get me out
of the trouble.
Sean

I'm a little unclear about your question. What is the exact error that you are receiving and at what point are you receiving it? Is the error occurring when calling the DLL in LabVIEW or is it occurring when building the DLL in Visual Studio? Further clarification about exactly what the problem is and where it is occurring would be a big help!

Can't build "hprof.dll" on Windows [JDK5.0]

Hello everyone!
Now,I am trying to build "hprof.dll" on windows, because I want to customize "Hprof".The "hprof" source code is included in "JDK DEMO(see %JAVA_HOME%\demo\jvmti\hprof\src)".

Because "sample.makefile.txt" is for GNU make, I tyied to build using Cygwin and GNU make.
but the same compile error went out.

I have no idea how to deal with this error.
Who can help me about this problem ? please give me some answers!

Do you have the specific name of the C++ compiler you are using?

Error message MSCVR80.dll missing when updating iTunes

I have been trying to update iTunes but keep getting an error message MSVCR80.dll is missing
I have tried deleting iTunes and reinstalling but get error message
My brother in law has the same message and problem and he is in another State

Uninstall your existing copy of iTunes. Delete any copies of the iTunesSetup.exe (or iTunes64Setup.exe) installer files from your downloads areas for your web browsers and download a fresh copy of the iTunes installer from the Apple website:
http://www.apple.com/itunes/download/
(The current build of the 11.1.4.62 installer was changed a few days ago, which fixed the bulk of the reports of MSVCR80.dll/R6034/APSDaemon.exe/Error-7/AMDS-could-not-start trouble ... but the build number on the installer was not changed. So we're trying to make sure you do the reinstall using a "new good" 11.1.4.62 installer instead of an "old bad".)
Does the install with the new copy of the installer go through properly? If so, does that clear up the error message?
If you still have the same error messages cropping up, then try the procedures from the following user tip:

How to remove the "int len" of my return string on the DLLS header when building a DLL on LabVIEW 8.5

Hi all.
I'm building a DLL on LabVIEW and I choose a string as an output on the terminals connectors.
But LabVIEW creates another output, the lenght of the return string.
This is a problem because I have other DLLs and I need them to be compatible.
How do I remove this length from the header? What is the difference between Pascal String and C string and String Handle Pointer?
String Handle Pointer removes the length from the header but I don't know the difference between this data types.
Thanks in advance for the help.

C string pointer is a pointer to a memory location whose string information is terminated by a 0 byte. Pascal String Pointer is a pointer to a memory location where the first byte specifies the number of bytes to follow. This obviously allows only for strings up to 255 character length.
LabVIEW String Handle is a pointer to a pointer to a memory location where the first 4 bytes are an int32 value indicating the number of characters to follow. You can read such a String handle in a function without many problems, but you can only create, resize and delete such a handle by using LabVIEW memory manager functions. So this makes only sense if the caller of such a DLL is LabVIEW too as another caller would have to go through several hoops and tricks in order to gain access to the correct LabVIEW kernel that could provide the memory manager functions to deal with such handles.
Last but not least output strings whose allocated length is not passed to the funciton as additional parameter are a huge secerity risk (talk about buffer overrun errors). LabVIEW DLL Builder does not support the creation of DLLs with output string (or array parameters) without the explicit passing of an additional parameter telling the DLL function how large the allocated size is (so that the DLL function can make sure to never write over the end of the buffer).
The additional length parameter only disappears for String Handles because LabVIEW will simply resize them to whatever length is necessary and that is also the reason why those handles need to be allocated by the same memory manager instance that is also going to execute the DLL function.
Resizing of memory pointers is non-standardized and in normal circumstances not suited for passed function parameters at all.

Report Generation Toolkit - Error message rpcrt4.dll

Hello
My labview app. calls functions from the Report Generation Toolkit. I tested the runtime version, and this work fine under in Windows NT and Windows 2000, but does not work under Windows 98. I got and error message say "rpcrt4.dll Page not valid" that seem come from Windows and is related to a Remote Procedure Call. I already check the version of this dll 4.71.2900

The rpcrt4.dll is part of the DCom98 package. I have seen other problems, unrelated to LabVIEW, with this .dll arise when other programs have installed different versions of some of the DCom DLLs. You may want to consider trying this program out on another Win98 machine, or you may want to search through the Microsoft Support page for errors with this dll, specifically with the error number in the message you receive. The ones that I have seen have suggested restoring the DCom dlls to the original ones from the Win98 disk. There is also an update to the DCom components for Windows 98 (version 1.3) on the Microsoft website.

Prompted to upgrade iTunes on computer. Won't let me and get error message MSVVR80.dll not found. Attempted to reinstall, won't let me. Can you have iTunes and iCloud on the same computer?

when I debug in VB it stops in line saying set oSboGuiApi = new SAPbouicom.sboguiapi
I'm using windows 2003 server. Any idea how to solve?

Hi,
Have you check that you use the correct license file ? I mean the license file version could be one of the possible cause.
Rgds,

Error loading in DLL (Crystal reports 2008 version 12.3)

we have installed the software but While adding the reference in VB,and while selecting the (Crystal Report ActiveX Viewer 12.0) we can't add as a reference it is showing (error in loading DLL) so please request you to check this error which is attached and revert on this As early as possible.

Thread moved to the NET - SAP Crystal Reports forum.
For timely response, it is important to make sure you post to the correct forum (check the header of each forum).
From your description, I suspect that you are trying to use the COM based Report Designer Component(?). This component has been retired in CR XI R2. The activeX viewer you are trying to access is only included for internal purposes and you are not licensed to use it at all. In CR 2008, you will have to use the CR SDK for Visual Studio .NET.
