Attachment is the upload this DLL,
If operated by labview will than VB simple some?

How to upload attachments which ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

CodePudding user response:

BBS posts do not support the attachments, and through the network location to share it,

To the left of the "BBS" home page, a "CSDN network location",
In fact this is baidu, you go in, build a folder, what you will upload into,
Then create a "Shared links" and share the link url sent come,
Pay attention to the "private sharing" to the password also posted, open sharing of wouldn't have the password,


Don't know what you ask is "what", labview, what is the relationship between the
But if the corresponding hardware related operations, estimates are much harder to solve,
People here do not necessarily come into contact with these things, and no experience,
If you want to "try", there is no corresponding hardware I'm afraid I can't go to try,

Below A replacement for VB6, B for calling you this DLL in VC:

Don't be A language code is modified to B language code busywork,
Also don't use A language code to directly invoke B language code base, this complicated things so easy to get wrong,
Just make A, B language code of input and output is redirected to A text file, or modify A, B language code let it through text file input and output,
Can easily make A, B coordination between the two languages,
For example:
A will request data written to A file a.t xt, renamed after finish aa. TXT
B find aa. TXT, read its contents, call the corresponding function, and writes the results file b.t xt, after finish delete aa. TXT, changed its name to bb. TXT
Found A bb. TXT, read the content, after finish delete bb. TXT
Above can be replaced by any kind of A language or development environment, B can be replaced by any kind of with the development of A different language or development environment,
Unless A or B does not support to determine whether A file exists, file read and write and file name,
But who can name does not support to determine whether a file exists, file read and write and file name for the development of language or development environment?
Can put the temporary files on the RamDisk efficiency decrease wear disk,
Data structure is very complex, a text file format problems refer to a json or XML

The communication methods between the temporary text file sharing this process there are plenty of advantages, compared to other method only listed below I can think of now:
Loose coupling between process,
Can be on the same machine, process, also can cross machine, across the operating system, hardware platform, and even multinational,
, convenient debugging, and monitoring, only let the third party or artificial view the temporary text files,
Switch, convenient online service, need to delete or create the temporary text files,
, is convenient to realize distributed and load balancing,
Services to provide convenient, queue, queue is full and it is almost impossible to happen (unless the hard disk space full)
DE...

"Across different languages, machine, across the operating system, hardware platform, multinational, cross *. *" misery,
Back is "the use of Shared a plain text file information communication" of the shore!
