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.

  • If Then Statement Help

    I'm new to xBasic, so I don't know much. I have this code that I want to run ONLY if the variable nFacilityID is not equal to 0. When I run the program though, the code gets executed anyway. I know for a fact that the variable is 0 because all the records in the db have a value of 0. What do I have wrong?

    If nFacilityID <> 0 then
    dim conn2 as sql::Connection
    flag = conn2.open("::Name::MedLook DB")

    dim argHosp as SQL::Arguments
    argHosp.Add("HospNumber", var->nFacilityID)

    dim sqlCommand as c
    sqlCommand = "SELECT id FROM DocIdent WHERE Id = :HospNumber"

    flag = conn2.Execute(sqlCommand,argHosp)

    dim hospRs as sql::ResultSet
    hospRs = conn2.ResultSet

    parentform:cmbFacility.value = convert_type(hospRs.data(1), "character")
    End If

    Re: If Then Statement Help

    You don't say where/how nFacilityID is populated with 0. Just to check, insert a debug in your script.

    debug(1)
    If nFacilityID <> 0 then
    dim conn2 as sql::Connection
    flag = conn2.open("::Name::MedLook DB")

    dim argHosp as SQL::Arguments
    argHosp.Add("HospNumber", var->nFacilityID)

    dim sqlCommand as c
    sqlCommand = "SELECT id FROM DocIdent WHERE Id = :HospNumber"

    flag = conn2.Execute(sqlCommand,argHosp)

    dim hospRs as sql::ResultSet
    hospRs = conn2.ResultSet

    parentform:cmbFacility.value = convert_type(hospRs.data(1), "character")
    End If

    the debugger will appear when the script executes. You can type in nFacilityID in the expression list at the bottom, hit enter, and you will see the present value.

      I set nFacilityID to the value of a column in a browse. It gets set whenever the user double clicks on the record in the browse. I just set the variable equal to the FacilityID in the selected record.
      Also, nFacilityId has the scope Layout.

      I tried the debug thing and nFacilityID does not have a value. So is the value NULL or ""?

        I just set the variable equal to the FacilityID in the selected record.
        How and what scope?
        Your problem script may not be seeing the variable.

          You could just refer to the browse column value of the current selected record.

          If parentform:browse1:nFacilityID.value <> 0 then
          using the appropriate browseobjectname.

            Re: If Then Statement Help

            I have all my scripts in different sections of In-Line xBasic, as you can see in the first picture. The top script populates the variables with the selected browse values, which you can see in the second picture.
            The only difference between populating the doctor and populating the facility is that the doctor has a value in the browse, and of course the variable names and sql statement. Populating the doctor works fine, the nDocId variable i use does not give me any trouble

            I tried using the parentform:Browse1:Facilityid.value in the If statement and it did not work either. I tried it as parentform:Browse1:Facilityid.value <> 0 and also parentform:Browse1:Facilityid.value <> "". neither of them worked.

              Re: If Then Statement Help

              When I do something similar and I want to reference the variable elsewhere I dimension it as shared and I get

              DIM SHARED test AS c
              test = parentform:Browse1:Dir_ew.value

              I don't see the dim statement in your inline xbasic. Are they dimmed elsewhere?

                I just defined it from the menu bar Form->Variables. I redeclared it as a session variable and it has no effect.

                Is there a way to see if a numeric variable is empty?

                  place - msgbox(str(nFacitityID,12,4)) - after the line the variable is populated and a message box will open and display the value.

                    The str(nFacilityID,12,4) did the job. Just did IF str(nFacilityID,12,4) <> "" then. Works good now. Thanks for the help!
