Dialog Save or Open

[Weldon_Teixeira]

It's a little hard to find a way to make a dialog to save or open file with more then one option.

I have done a dll in DEV-C++ to solve this problem.

The dll project was made at "c" format. 

 http://rapidshare.com/files/188811855/LabVIEW_-_Dialog_Open-Save_DLL_example.zip

 It's necessary to insert some Linker Parameters at Dev-C++ menu: Project / Option / (tab) Parameters / (textbox) Linker.

Put there the following parameters: 

-lgdi32

-lcomctl32

-lComdlg32

This dll was tested at LabVIEW 8.5 and 8.6.

If there is a better solution I'd like to know...

Thanks.

For some reason, i can not open the file.

Can you post the dll as attachment ?

I downloaded, but I have to admit I don't quite understand the intent of this code. If you want to change something (like the list of filetypes) you have to go back to the C code, recompile it, and then (possibly) update the LabVIEW code. How is this a better solution than simply calling the Windows API functions directly, as they provide the necessary functionality?

The dll file is inside of the zip file at rapdshare site:

 I don't know a way to post here any file. If you want to, I should send you a email with the zip file.

 Good luck

Hello,

I have seen some solution that I found, but, no one ran fine.

My example is necessary to change the code and recompile the dll file

for making your desired extension file. 

It's not very bad, since, in your application you just need to handle few file formats.

If your application must to handle several file formats you should set the 

filter for every file (*.*) .

Now, if you have a beter solution, for instance, calling Windows API directly,

I'd like to know how to do that, if you please. 

Thank you for commenting.

The Multiple File Selection Dialog example does the open file operation in pure G.

There's also the example over at LAVA that uses no Windows API calls.

You can also do this in .NET.

I have seen a alike solution, but, did not run properly.

The  solution that you have shown run fine, but,

its code is a little big. Although, it's a good solution

I'll keep using the dll that I have done, but, I keep

your example. 

Of course, It's possible to make a subVI.

Thank you vey much

A "little big"? Based on what criteria? Regardless of this seemingly arbitrary conclusion, your particular implementation has one critical flaw: It does not allow reuse. If you want to use different file patterns you have to rewrite the DLL. Pardon me for being blunt, but how can you possibly believe that to be a better solution?
