Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Re: Variable not found

    Hi Tom H.,

    Originally posted by Tom Henkel View Post
    I've used addin varaibles extensively.

    To clarify what is happening:

    Code:
    dim adddir as P
    adddir = addin.variables()
    The above code defines a pointer "adddir" to the addin variable space. As yet, there is no specific variable defined in that space.

    When you defined

    Code:
    adddir.varname = "d:\\"
    you set the variable "varname" in the addin variable space to be "d:\".

    Remember, the label "adddir" is just a pointer to the space.
    This is not quite correct. The
    dim adddir as P
    is creating a local pointer to the addin variable space. That local pointer only exists while the current script or function is running. After that code finishes, the local variable goes away. That is why it is not available elsewhere.

    However, after the pointer is created in the code, he assigns a variable
    adddir.varname = "d:\\"
    This creates a variable property called varname in the addin variable space. That property will still remain in the addin space, even after adddir pointer variable goes away. The addin space didn't go away, just the pointer to it.

    All you need to do is later recreate another variable whenever you need it, as in
    addin_space_ptr=addin.variables()
    and reference the needed properties as in
    x=addin_space_ptr.varname
    Alternatively, one could have created a global pointer, and then the global pointer could be used, but global variables (which persist until the database application closes) and addin variables (which persist across all databases that are opened until Alpha Five closes) should only ideally be used for parameters that need to be referenced in many locations, eg. color styles, directory locations, etc.

    I suggest reading my tips on variable scoping here

    Re: Variable not found

    Thanks for the tips. It's working. In the script executed from the form I added :

    adddir = addin.variables()
    base_path = (adddir.varname)

    Many thanks!

    My reading of the documentation says

    Code:
    dim adddir as P
    adddir = addin.variables()
    adddir.varname = "d:\\"
    is correct followed later by

    Code:
    base_path = adddir.varname

    I don't have first hand experience with addin.variables().

    However, don't you want to set the scope of the adddir var to global to be able to see it outside the autoexec?

    Variable not found

    I created a global variable to define the location to save my reports: glodir = "g:\\"
    I'm able to refer to the variable by just using the name “glodir” in the script: base_path = (glodir)

    I prefer to use a addin.variables() to define the location to save my reports so I created autoexec script:

    Code:
    dim adddir as P
    adddir = addin.variables()
    adddir.varname = "d:\\"
    and tried it with:

    Code:
    dim adddir as P
    adddir = addin.variables()
    adddir = "d:\\"
    After executing the script from a form it says: variable "adddir"not found. Either the code I'm using in the autoexec script is wrong or I refer to the addin variable in a wrong way. Maybe even both?

    The whole script:
    Code:
    topparent.commit()
    
    if isnotblank("adm_bezwaar->Bz_F_Nr") then
    tbl = table.current()
    
    factuur = alltrim(adm_bezwaar->Bz_F_Nr)
    number = alltrim(tbl.adm_nr)
    client = alltrim(tbl.clientname)
    
    'global variable works
    'base_path = (glodir)
    
    'addin variable doesn't work
    base_path = (adddir)
    dir_name = number+" "+client
    dir_create_recurse(base_path+dir_name)
    
    
    Parameter1 = eval("Bz_f_nr.value")
    filter = "F_nr = [varC->parameter1]"
    query.filter = replace_parameters(filter,local_variables())
    query.order = ""
    
    sav_nam = base_path+dir_name+"\\"+"factuur"+SPACE(1) +factuur+ ".pdf"
    report.saveas("facturen algemeen", "PDF", query.filter, "",sav_nam)
    
    sys_print(sav_nam)
    
    end if
Working...
