I have had an ccd camera and it's software. I would like to drive the ccd camera by using igor. The software has DLL. I would like to call the DLL from Igor. I bought an Igor XOP toolkit7. AIthough,I don't have visual C++ and I'm not a programer. please show me how to control the camera by igor via dll. On the other hand, I can use a Labview program and it has already prepared the node for " calling dll code". It was useful when calling the external dll to labview. I wish anyone supporting me to build the XOP smiliar to the labview node.

Writing a camera XOP is not trivial even when you are a seasoned programmer. You do indeed need the XOP Toolkit, VC++ and experience writing code on Windows. Since you say that you are not a programmer I recommend first checking to see if an XOP was already written for the particular camera. Otherwise be prepared for a steep learning curve to master the required details.
Normally, with camera SDKs I use a static library that provides all the routines you need to communicate with the camera. If you have to use a DLL you should look at the LoadLibrary() function.
Thank you for thinking about this. The ccd camera is provided from our group company. Statics DLL? is prepared for customers. I will attach the documents about the DLL. I thought I will be able to communicate the CCD camera by Igor6.2 via the DLL easily, if it will difficult for me I will make aquisition program by using Labview and I will make a DDE commnication program by Igor. I could communicate the SDD X-ray energy dispersive detector by using this metode before. I should constructed the measureing system as soon as possible. But in this case, I would tried to control the ccd only by using igor because it will become a simple program of aquisition system.
A super hacky solution, in case an xop is too much, might be:
1) reading the functions in the dll with dependency walker or similar
2) use:rundll32.exe dll_file, function_name arguments to test (rundll32 help)
3) call the functions from within Igor with ExecuteScriptText (displayhelptopic"ExecuteScriptText")

FYI, Igor 7 and beyond have dropped support for DDE, so if you go that route you're locking yourself into using an already very out of date version of Igor. Writing an XOP is most likely the "right" way to do this. I took a very quick look at the SDK documentation you provided and I think writing an XOP would be relatively straightforward for someone who is familiar with XOP writing.

@Nadeon: There is a list of third party consultants listed at https://www.wavemetrics.com/products/thirdparty/developers.htm which can help with the XOP writing.
Disclaimer: I'm on that list too.

You are right on both accounts.
Here is a quick test:
string s_dll
string s_func
string s_arg
string s_cmd
sprintf s_cmd, "RUNDLL32.exe %s,%s %s", s_dll, s_func, s_arg
executescripttext s_cmd
end
rundll32("user32.dll", "LockWorkStation", "")
best,

Just a upvote for Thomas. He wrote a custom XOP for Basler cameras for me. Works well.
