MySQL UDFs using libmysql.dll functions: most functions from MySQL API all are prefixed with an underscore: _MySql... e.g.: _MySQL_Real_Query( sometimes parameters are chaged - read function descripti

I don't get it. @mLipok has polished (pun intended) a nice ADO UDF which works flawlessly. Why insist on using another one which causes issues?

@ProgAndy I like anything that smells to SQL !! Unfortunately you link does not work (for me ?). Rgds ptrex

@maniootek Sorry, I cannot show the code as its a project of one of my clients!

Anyway, I have already found out the problem, the AV was blocking calls to the DLL!

Here we have another strange issue again... Have anyone of you guys experienced a black hole? I mean, not a physical black hole :P, but a internet blackhole

I have a situation where sometimes the selected records don't get received and I get an empty array:

And sometimes the Query which I send to the MySQL server never reaches to it... Also, in both cases NO error was being reported.

Theres a bug in this UDF that needs to be fixed.  If your querying a field, and the field is blank, it gives you zero.  Well what if the field is actually zero?  Theres no way to tell if the field is actually blank, or actually zero.

 

$data = DllStructGetData(DllStructCreate("char[" & $length & "]", $fieldPtr), 1)

should be:

$data = DllStructGetData(DllStructCreate("char[" & $length & "]", $fieldPtr), 1)
            if @error then $data = ""

I am trying to read LONGBLOB data from a remote MySQL db, and then display the retrieved image/pic in an autoIT GUI. Would you have any examples of how to do this?

Briefly, what the below does is insert an image on my c:\ drive to a remote MySQL server. Using MySQL Workbench, I can see the image is stored as a BLOB and that the image looks fine when I open up the BLOB with Workbench.

The next part is where I am having difficulties. I am able to run the select, but clearly, since the data is a BLOB, it does not view properly in the different methods that ProgAndy uses in his included test.au3 file since he is displaying it as a string array. I was wondering what I could do to have the image show up in a very simple autoIT gui?

  MsgBox(0,"Error:",$errno & @LF & _MySQL_error($MysqlConn))
  If $errno = $CR_UNKNOWN_HOST Then MsgBox(0,"Error:","$CR_UNKNOWN_HOST" & @LF & $CR_UNKNOWN_HOST)
 Endif

$f_handle=FileOpen($file,16)
if @error <> 0 Then
 MsgBox(0,"Error:","file open error " & @error & @CRLF)
EndIf

$contents=FileRead($f_handle,FileGetSize($file))

 if @error <> 0 Then

You'd certainly gain from playing with Greencan example:

His code uses SQLite as the DB engine but can obviously be transposed to any ODBC or non-ODBC API.

Hi and thanks for pointing me to that demo. Got it working for that demo in no time. The issue is that it does way more than I actually need and I have spent most of the day trying to convert it from using SQLite to MySQL UDF and I am struggling big time....I can't seem to figure out the portions of this demo that I should be extracting for use and I can't migrate it to MySQL either... :-(

One example is the use of the PRAGMA commands.

I will keep trying here....

OK. so I am focusing on the _Execbin function. My biggest problem is that when I debug the BLOB to the console in my script compared to the demo, the data returned in mine is only 4 characters in length.

I don't understand the dllstructgetdata command but I think this is where it is failing. I also think there has to be a simpler way to read the 1 record returned as BLOB to $data, but I cannot figure it out...

I'll have to leave that to someone used to this UDF. I'm not even a MySQL user so I can't give you any good advice here.

I managed to figure out what was going on. Essentially the dllstruct was of type char instead of byte. Secondly, in the example, there was always a file name within the header with a null character. Since I was not loading the data with the embedded file name with the null character as the blob header, nothing was working.

I am going to clean up the code a bit and post it later. I am super happy this worked...thanks for pointing me to greencans demo.

So the biggest issue I had was understanding the DLLStruct commands. Turned out that I needed to change it from char to byte and as well to upload the files with a proper header that included the filename.

Retrieving and displaying the image can be done with the following (Kudos to GreenCan and others!). Essentially, _Execbin(PK) performs a query and returns the blob based on the clientID which is the Primary key on the table.

Hello everyone.

 

I have a problem with "Error: 2006 MySQL server has gone away".

Because i want to send a binary data of a big picture to the MYSQL server.

I have read the documentation of mysql "https://dev.mysql.com/doc/refman/8.0/en/gone-away.html".

Maybe I think the issue is that the max_allowed_packet is too small.

20180515113504.thumb.jpg.c2cd051fad28eba7678a8ee69b7016f2.jpg

I didn't know how to set the value of max_allowed_packet on the client side.

Please help me thx.

@Xwolf You cannot modify server configuration from client side

@TheDcoder

In fact, I can modify the set from remote MySQLServer throught browser.

And i checked the set of server side, the value is 1073741824.

Now i want to modify the value of the client side.

Well, modifying it from the browser is different from doing it via an SQL connection :)

If the value on the server side is greater than what you want, then it is enough, you don't have to modify anything on the client side to make this work. However, seeing how the server is still disconnecting, there might be some other setting or 3rd party software on the server which is preventing the connection transfer large amounts of data.

I recommend you check the server and see if everything is in place, look for configurations which might be over-riding the 1 GB limit.

OK

I will do that what you say.

Thank you very much.

      Hi all,
      My programming knowledge is very basic.
      I have an old script that creates shares and assign permissions. It normally registers SetAcl.ocx if necessary and creates an object to assign permissions.
      The command that registers SetAcl was apparently working fine under Windows 7 but is not working under Windows 10.
      RunWait("regsvr32.exe path\to\setacl.ocx /s", "", @SW_HIDE) As I'm logged in as admin, I changed this command to :
      RunAsWait(@UserName, "", "", 0, "regsvr32.exe path\to\setacl.ocx /s", "", @SW_HIDE) It seems to terminate correctly but the script still doesn't work as expected.
      To check that, I've created that small script :
      Local $objSetAcl = ObjCreate("SETACL.SetACLCtrl.1") If IsObj($objSetAcl) Then ConsoleWrite("Object successfully created." & @CRLF) Else ConsoleWrite("Object not created. Registering SetAcl.ocx" & @CRLF) Local $result = RunAsWait(@UserName, "", "", 0, "regsvr32.exe path\to\setacl.ocx /s", "", @SW_HIDE); Use of my admin username to elevate CMD ConsoleWrite("Return code : " & $result & @CRLF) ConsoleWrite("Creating object" & @CRLF) $objSetAcl = ObjCreate("SETACL.SetACLCtrl.1") If IsObj($objSetAcl) Then ConsoleWrite("Object successfully created." & @CRLF) Else ConsoleWrite("Object creation failed." & @CRLF) EndIf EndIf It tries to register SetAcl.ocx, return code 0 seems to be fine but still can't use SetAcl.
      But if I go to CMD as admin, run the regsvr32 command and restart my script, it can create the object without issue.
      I know my poor knowledge makes me miss something. Anyone can help me figure this out ?

      Dear members of the forum,
      I'm working on a project in which I have to use Image recognition technique. 
      Due to client restrictions, I couldn't use AutoIt for this project. 
      Is there a way to use this DLL "ImageSearchDLL.dll" (which is used to do image recognition steps in AutoIt) in VB.Net to achieve the same result? 
      I have used this DLL few years before and got good results. If there is a latest version of this DLL and if you can share it, that will be helpful too.
      Any guidance is deeply appreciated.

      Hi AutoIt Scripters/Programmers. I have a question about MIME Tools for Notepad++:
      I've recently found a UDF about Base64 in forum, but they can't decode\encode correctly some emojis , other UTFs and etc. so i decided to use mimeTools.dll of Notepad++ or main site
      My problem is how to use this dll in AutoIt Language?

      I will be happy with your comments and answers❤ Thanks.

      Good morning Forums 
      In these days, I am working on a project that involved me to use some Windows APIs to obtain some information about Terminal Servers.
      I'm doing this using wtsapi32.dll in a VBA Project, but, the lack of knowledge about few things threated in the articles make this quite difficult to
      implement and understand at the same time.
      The most difficult thing I'm facing is "translating" C/C++ functions or struct in VBA when pointers are used, or pointers of pointers, and so on.
      Since VBA seems to not have a pointer type, to make those functions work I need to implement other functions taken from other DLLs, and this confuses me a lot.
      For example, starting from this code, I splitted all the functions and all the definitions to understand why they are there, and why I need to use them.
      At the end, I've found out that the code I was going to implement starting from the functions provided in the Microsoft Docs won't be ever be able to work without some supplementary functions which are not mentioned anywhere.
      So, I was wondering if someone would please point me out to a good and practical exaplanation about pointers (in general) or specifically for VBA, because I need to use them quite often in these days, and I'd like to understand what I am doing.
      Thanks in advance.

      Best Regards and Stay at home 🏡
