HTBDDE dll

[ZeRider]

Hi,
Do you know if there is a limitation of the number of request on an EXCEL worksheet through the HTBDDE dll ?
When I run this part of my programm I receive the error below after 16238 good data transfert from EXCEL to HTBasic …

Microsoft Visual C++ Runtime Library
Runtime Error!
Programm: C:\Program Files (x86)\HTBwin 10.1\HTBwin.exe
This application has requested the Runtime to terminate it in an unusualy way.
Please contact the application’s support team for more information

Hi ZeRider,

I put together a sample program and a sample excel file to try and reproduce the issue you are seeing above. I am able to consistently read all 200 rows of 259 cells. The difference could be in the data being read in since I am not certain the format of your data. Here is a link to the excel file I am using:

sample.xlsx

And here is my sample program:

my sample program:

      CONFIGURE LONGFILENAMES ON

      DLL UNLOAD ALL

      LONG Hconvexcel! Excel conversation handle
      LONG Retval  ! Return value for the DLL functions

      DLL LOAD "HTBdde"
      DLL GET "LONG HTBdde:Ddeconnect"
      DLL GET "SHORT HTBdde:Ddeterminate"
      DLL GET "LONG HTBdde:Ddetimeout"
      DLL GET "SHORT HTBdde:Ddeexecute"
      DLL GET "SHORT HTBdde:Ddepoke"
      DLL GET "CHARPTR HTBdde:Dderequest"
      DLL GET "SHORT HTBdde:Runexe"

    ! Connect to the Excel System topic
      Hconvexcel=FNDdeconnect("Excel","System")

      IF Hconvexcel=0 THEN

          Retval=FNRunexe("C:\Program Files\Microsoft Office\root\Office16\Excel.exe",1)
          WAIT 2
          Hconvexcel=FNDdeconnect("Excel","System")

         ! If we still couldn't connect, Exit
          IF Hconvexcel=0 THEN
              GOTO Exit
          END IF
      ELSE
            ! Create a new workbook
          Retval=FNDdeexecute(Hconvexcel,"[Open(""C:\Program Files (x86)\HTBasic 2021\DLL Toolkit\Samples\HTBDde\sample.xlsx"")]")

          IF NOT Retval THEN
              PRINT "didn't open"
              GOTO Exit
          END IF !
      END IF

     IF Hconvexcel=0 THEN
          GOTO Exit
      END IF

      DIM C$[20]
      DIM Return$[50]

              DISP Total,C$,Data$(Line,Column)
          NEXT Column
      NEXT Line

      PRINT "Finished"

 Exit:!

      IF (Hconvexcel) THEN

      END IF

Hi PatB,
Thanks for help and test.
I made some modifications in my code according to yours (please find below my complete updated code)
Unfortunatly after a lot of tests on different computers, 2 different EXCEL version, 2 different HTBDDE.dll version, different EXCEL files (including one completely blank EXCEL file) I always have the same error.
My maximum number of read is 16379 (L64C62) …!!!
Please could re-test my last code on your computer and verify on your side ?
Thanks again
Regards,
ZeRider

I’m not able to run your sample program because I don’t have a local copy of Excel installed. Mine is the cloud-based Microsoft 365 subscription which doesn’t have a local excel.exe file that can be called. However, as a workaround, I used the sample.xlsx file that Pat provided and did a SAVE AS in CSV format. You can do the same with your data file. I then wrote the below program you can try out that gets the data directly from this file and into the same array, probably faster than going through Excel. However, this assumes there are not embedded commas in your string data.

Another problem with the Excel interface is you are not getting the HTB error code which could be any number of things. So it’s hard to troubleshoot without knowing the exact line number and error code/message that is causing it to fail.

Also, since you have been helpful on the forum to others, I could get you a complimentary license key to HTBasic 2021 so you could try that out and see if it makes any difference. If you are interested, send me an email at htbsupport@transera.com.

Thanks,

Ralph

Here’s the program:

OPTION BASE 1
DIM Data$(200,259)[20] ! Final array of data
DIM Lines$(200)[5180] ! 5180 is 259 values times max length of 20 each
DIM R$[5180] ! temporary comma delimited row string
DIM Col$(259)[20] ! temporary single row array of extracted column values
F$=”your folder path to data file”
ASSIGN @Samples TO F$&”\sample.csv”;FORMAT ON
ENTER @Samples;Lines$(*) ! get all 200 rows of data
ASSIGN @Samples TO *

FOR Row=1 TO 200
I=1
R$=Lines$(Row)
GOSUB Split ! get comma delimited data from R$ into Col$()
FOR Col=1 TO I ! 259
Data$(Row,Col)=Col$(Col) ! transfer to Data$
NEXT Col
NEXT Row
PRINT “Total: “;Total
GOTO Exit

Split: !extract comma delimited values from string
P=POS(R$,”,”)
IF P>0 AND P

Looks like some of the code got cut off. Here it is again.

OPTION BASE 1
DIM Data$(200,259)[20] ! Final array of data
DIM Lines$(200)[5180] ! 5180 is 259 values times max length of 20 each

DIM Col$(259)[20] ! temporary single row array of extracted column values

ASSIGN @Samples TO F$&”\sample.csv”;FORMAT ON
ENTER @Samples;Lines$(*) ! get all 200 rows of data
ASSIGN @Samples TO *

FOR Row=1 TO 200
I=1
R$=Lines$(Row)
GOSUB Split ! get comma delimited data from R$ into Col$()
FOR Col=1 TO I ! 259
Data$(Row,Col)=Col$(Col) ! transfer to Data$
NEXT Col
NEXT Row
PRINT “Total: “;Total
GOTO Exit

Split: !extract comma delimited values from string
P=POS(R$,”,”)

Hi Ralph,
Thanks a lot for your alternative method. That’s a really good idea that I hadn’t thought of 🙂
Please find below my new code applied …
I note your proposal for the HTBasic 2021 test, I will send you an email very soon

LTK

PS:
I confirm it’s not easy to paste HTBasic code in the forum.
I’m very curious to know how PatB managed to keep his indentation in his message !

Hi ZeRider,

I wanted to see if I could reproduce the failure at line 16379. Using your program in HTBasic 2021 I could not get it to fail. It completed successfully every time. I did see that you were using HTBasic 10.0 and HTBasic 10.1 so I tried those versions and immediately get an error in each and they shutdown which is very odd. If I get the time I will look into it, although since it works fine in our latest release, my recommendation is to use it.

Ralphs suggestion is a good one and will be much faster than going through Excel, but if you need to go through Excel for some reason, I would recommend using HTBasic 2021.

Concerning how I entered my code in my post, I use the HTML CODE tags provided on the toolbar above and put my code between them.

If you do get a copy of HTBasic 2021, I would be interested to know if HTBDDE works successfully for you, or you still hit the same issue.

Thanks!

[ZeRider]

Hi PatB,
my test results with HTBasic 2021 are not better. The program stops and closes without an error message. According to my displays this happens while it tries to read the values on line 64 but the column seems more random…
Well anyway, I’m going to use the alternative method recommended by Ralph which works whatever the HTBasic version.
I put here my code using EXCEL reading which is defective

Thanks PatB for your Tips.
The code display is beautiful now 🙂

I’m not sure if it will make a difference, but I noticed that you are checking for version 21.1.009 of HTBasic, but the current version is .015. You should download that version to have the latest.

Hi Ralph,
please could share me the link where I can download the latest HTBasic version ?

[RalphW]

You can download the latest version of HTBasic from the website by clicking “Downloads” on the menu. Then click “Download Purchases”. Here is the link: https://transera.com/dl-htbasic/

Hi all,
Thanks for the link. I downloaded the last HTBasic version 21.1.015 and the results are indeed differents.
With this new HTB version the program don’t stop now before the end but from L64C64 cell, the reading in the EXCEL file are always empty (Return$=””)
Very mysterious …

This may not be relevant, but on versions prior to 10, there was a 256-byte limit on transfers via the htbdde dll. Has that been fixed? I had to use the Techsoft dde driver to get around it.
