Line Graph Data Storage/input
Aug 24, 2006
hi all,
got a wee problem... i have a number of graphs showing volume (x axis) and pressure (y axis) for particular pipe sizes.... (it's for pneumatic conveying)
depending on the resolution of the hand drawn graph there could be 100's of points along a single graph line (x and y points)....
My program basically needs to select a point(x and y) closest to the graph line that it intersects. (come on mech. engineers)
Problem is how should i store / input the graphs into the db file?
I'm trying to avoid have to literally input every x 'n y point per line per graph... there are about 20 lines per graph and a 100 odd graphs!!!
I was thinking of inputing a start and end point then use some sort of formulae to draw a logical line and pick up all the xy points i need, then store them...
Any thoughts?
Thanks

I can change multiple things on a line graph with VBA.
Me.Graph47.chartType = GraphType ' take 65 for line
with me.graph47
.SeriesCollection(1).border.Color = vbblue ' change the line color
.SeriesCollection(1).border.Weight = LineWeight ' change the line weight to for example 3
.SeriesCollection(2).MarkerSize = MarkerWeight ' Change the marker weight, for example 4
.SeriesCollection(2).MarkerBackgroundColor = vbblue ' Change the marker color,
.SeriesCollection(2).axisgroup = 2 ' put this series on the secondary axis
end with
SeriesColection(1) is line with markers. This is correct.But now I want the seriescollection(2) without line, so only the markers. I cheched the MSDN site from Microsoft. The Excel trick with the macro does not work for me.how to hide the line with VBA for only SeriesCollection(2) in Access?

I want to be able to take two separate queries to create a 2 line graph. Also to be able to spice the graphs up some. The ones I have done, single line, even seems dull.

(this is a repost )
I will skip the basic intro of "Hi im new to access and i dont know.."
anyways, what I am trying to search for and I dont know what Im looking for is this.
Q1) I would like to be able to open a zip file, read the NFO/txt file from within and import certain areas of the NFO file,the NFO file of course is layed out with ascii art but there is a predetermined area where certain info is obtained. for example: I would like to capture/import the URL, testers name, date avaliable, zip file name.THEN the text imported would be written to the database. It would be nice to figure out how you go about importing certain lines but im not sure how to ask the question and find the answer the right way. ie...(ascii art found here http://www.ascii-art.de/)
-= I did search import text and get text and didnt find what I was looking for=-
Q2) How do I write to an ascii file/nfo/txt using access, there is a template or a layout that is pre done,and i need certain fields filled out, just like they above layout.
thanks for all your help, you guys are awsome, and keep up the good work!

I found this page (http://support.microsoft.com/kb/824263) as a pretty good reference for field data types, but there's some things I still want to know.
What's the per-character storage on a Memo and Hyperlink field (ignoring compression)?
Are AutoNumber types (Long, Replication ID) unsigned?
Do null [non-text] fields still use their full capacity?

I had looked at the Shell() function but I don't see it doing anything such as input and output.
Does anyone know the use of the VBA's command line that would send an input and receive an output to the VBA's variable?

I have a report that contains 5 graphs, one for each day of the week. I run this report daily. When I run the report on a Monday, only the Monday graph displays data and the other graphs are blank as there is no data for that day just yet. Is it possible to hide these graphs if there is no data? I did find one suggestion to create a text box with the following code
Code:
Private Sub Report()
If [SumOfWed] = 0 Then
Me.Graph24.Visible = False
Else
Me.Graph24.Visible = True
End If
This does't work for me.Graph24 is the name of Wednesdays graph and the row source for the graph is TRANSFORM Sum([Wed]) AS [SumOfWed] SELECT [Machine] FROM [qryShiftDays] GROUP BY [Machine] PIVOT [Shift];

I created a number of graphs on forms that graph GamesSold vs RDate. If a game has no sales, there won't be any data. Is there a way I can add a label that will automatically display "Game is not yet released" and make it dependant upon the graph having data, and invisible if it does?

I have a (simplified) table with productnr., period (year and month) of sales, and sales (in currency). Now I want to know the contribution of the products that have their period of sales after a certain number. This will calculate the contribution to sales of new products. Simple stuff.. (i hope), but I was not able to do so...
I have managed to separate the table with multiple queries and I have managed to have now to queries that can show the sales of products that have been launched before the date and after the date, but combining the two tables is impossible for me..

My company wants me to run a high level report which ask for three filters. However as its high level they want it should run with a click instead of choosing filters from three drop down ...
As this report comes out as a graph I can't use report wizard to run tabular report. Any smart way that they click a button and get filtered data in graph form.

Here's the statement
Code:
sqlfinal = "SELECT Employees.ID, Employees.Name "
sqlfinal = sqlfinal & "FROM ((qryDeptVBA INNER JOIN qrySkillVBA ON qryDeptVBA.ID = qrySkillVBA.ID) "
sqlfinal = sqlfinal & "INNER JOIN Employees ON qryDeptVBA.ID = Employees.ID) "
sqlfinal = sqlfinal & "INNER JOIN qryAreaVBA ON Employees.ID = qryAreaVBA.EmpID "
sqlfinal = sqlfinal & "GROUP BY Employees.ID, Employees.Name;"
If i simply remove the GROUP BY line and stick the semicolon at the end of the previous line (.EmpID; ) it works just fine. How is adding a group by line causing an error?I tried adding another parenthes at the beginning ((( and ending the joins as EmpID); and that failed with the exact same error.

I have a main form with 3 sub forms. The main form is tied to a table called QUOTES_MASTER. The first sub form is tied to a table called QUOTE_ LINE_ ITEMS_DIRTGLUE. It calculates the subtotal when selecting items. The relationship is one-to-many linked on QUOTE_ID.
The second sub form adds up total of all line items and is not tied to a table.The third sub form adds ESTIMATED FREIGHT to the PRODUCT TOTAL and is not tied to a table. how to get the values from the line items form inserted into the QUOTE_LINE_ITEMS_DIRTGLUE table as they are added.
I also want to insert the total value from ESTIMATED DELIVERED into the LINE_TOTALS field in the table QUOTES_MASTER.I tried this code on the product total sub form but it doesn't do anything and there are no errors:
Private Sub PROD_SUB_AfterUpdate()
DoCmd.RunSQL "UPDATE QUOTE_LINE_ITEMS_DIRTGLUE SET QUOTE_LINE_ITEMS_DIRTGLUE.SUBTOTAL = Me.PROD_SUB WHERE QUOTES_MASTER.QUOTE_ID = " & Me.QUOTE_ID

I have a module which reads a CSV transaction file line by line and adds the correct transactions to an access table and places the wrong ones in a logfile.Now some transactions are rejected twice there is even one rejected six times. Whereas one wrong transaction is processed only once. I am certainly overlooking something obvious in the logic but what. Here is the relevant code.
Code:
Function ImportCSVForConfederation(inputCSV, ORG)
Dim TNO As Integer, TACT As Integer, TABLE As String, TLINE As String, I As Integer, J As Integer, K As Integer
Dim FLD1 As String, FLD2 As String, FLD3 As String, FLD4 As String, LogFile As String, LogPath As String
Dim Lim As String, ITNO As Integer
[code]....

Hi,
I have a form which records computer faults reported by users. On this form there is a subform for comment tracking eg. Phoned user, Date/Time. On the next line would be; Informed user to do this, Date/Time and so on. I have a button on my form which I would like to use to automatically put in a line of data. It is an aknowlegde fault button. What it hopefully would do is when you click the button it will automatically put in the date/time in the subform, Then the word "acknowledged" in the comment field, then prompt for the user name ( for the username field).
I am not sure on how to start the command. If i were to do it in the same form then I would just put something like;
me.Date.Value = Date()
me.Comment.value = "Acknowledged"
me.Username.value = "[Prompt]"
As you can see I have two problems though;
1. The data has to be entered in a subform
2. My Prompt I dont think will work.
Does anyone have any ideas?
Kind Regards
Keith

I am having a little difficulty with my importing in Access. Every time I import my text file, the lines will be jumbled. I have been reading up and I found this recordset code that seems to be what I need:
Code:
Dim strLine As String
Dim intLineNum As Integer
Dim MyDB As DAO.Database
Dim rst As DAO.Recordset
Open "C:TestTest.txt" For Input As #1
Set MyDB = CurrentDb
Set rst = MyDB.OpenRecordset("tblResults", dbOpenDynaset)
CurrentDb.Execute "DELETE * FROM tblResults", dbFailOnError 'Clear tblResults
[code]....
Basically, this code will extract data from the text file as long as it fulfills the Mid$ criteria. Here's where my problem comes. Each line in my text file is of different lengths and I have to capture the entire line.
I think using the Left$ function would work, but I don't know how to determine the character count such that the entire line of text would be inserted into the table.
Another difference between what I need and the code above is that, I am required to store each line into each row of my table, meaning
Line 1 is placed in Row 1 Column 1
Line 2 is placed in Row 2 Column 1
Line 3 is placed in Row 3 Column 1
.
.
.
Line X is placed in Row X Column 1.

I an trying to create a data entry form (IndividualsEntryFm) to input data for fields such as (First Name),(Birthdate) etc., these to be saved to the (IndividualsTbl)
I also have another table (NamesTbl) which has family names etc. The two tables are linked by a (MainID) field. I want a combo box on the individualsEntryFm so that I can select the family name. Then I wish the empty fields for the IndividualsTbl to be available to enter data.When I press the save button I then want this data saved, together with the MainID from the combo box to the IndividualsTbl.
I have set the IndividualsTbl with a (PersonID) field as an auto number each individual therefore has a unique PersonID but may well share the MainID. I'm trying to link many people to the same address.

I would like to filter data from a table using a query (from an data input form). The objective is to output all results if input form field is empty and to output results higher or equal to the type in the field if field is not Null. The query code is as follows:
IIf(IsNull([Forms]![Form2]![MaxDiffInput]);[Maximum operational pressure (bar)];[Maximum operational pressure (bar)]>=[Forms]![Form2]![MaxDiffInput])
However, is not providing any result when the input field (MaxDiffInput) as a value.

I have imported an Excel spreadsheet into an Access database. In Excel, a line break in a cell is entered by ALT+Enter. After importing my spreadsheet, all my line breaks appear as "□" and the text all runs together (no line breaks) in the table. The "□"s are also printed in reports. I need a way to either (1) make the "□"s appear as line breaks (e.g., by changing some Access property) or to convert the "□"s to something that shows as a line break in an the Access table memo field (e.g., CNTRL+Enter). Can anyone tell me how to make this happen?
I've tried to copy/paste the "□" into the Find/Replace dialog, but nothing appears when I paste. I understand the memo field is unicode, but I have not been able to determine what the "□" character actually is. It is not the same as the only similar squared shaped character I find in the Arial character map (U+25A1: White Square). I can copy and paste the "□", if surrounded by some other text, e.g., "xxx□yyy", into a Notepad document and it shows up as "xxx□yyy". Pasting the same into a Word doc and I get
"xxx
yyy" with the line break properly displayed. I can copy and paste just the □ itself in Notepad.

I'd like to run a search and replace on a query result to remove carriage returns, linek breaks and tabs from the data. I know that MSWord has character aliases that will allow you to do a search and replace - does Access have an equivalent for these?
Thanks!

Access 2010 report based on query based on 3 views using ODBC with the following sections:
Report Header
Page Header
Detail (1 - 3 lines)
Page Footer
The detail section has these lines...first line exits for all students, other 2 lines optional. Each line includes data from each of the 3 views:
Demograhic and bus/route information
Special needs information
Additional text information
Each student may have multiple lines in the detail section, one for pickup route, one for drop-off route and possible other routes.
Using VBA and the On Format event of the Detail Section, I have formatted the report to not display repeating information (not apply to use "Hide duplicates" feature) and not display either/both of the optional lines in the detail section.
All works well except that on the first line of each subsequent page, most of the data is missing. I have stepped through using the debugger and see that the data is returned by the query, but not displayed on the report.

I've read several previous threads regarding this...but could not find an answer:
Is it possible to store a PDF file in a table?
I know that I can store a hyperlink with the path to a PDF file located elsewhere, but I would rather store the file in the database itself.
If it can be done, how do you do it? Are threre drawbacks?
Thank you.

I was assigned by my manager to design an Access database system that is able to import all data from excel file monthly and creating charts & tables to analysis how each sales people and industry perform.
We originally have a big excel master sheet that has more than 10 sheets. I tried to import the current excel into access, but then i realized that this is not gonna work. because for next month, there will be new data and I can't do the whole import process over and over. Plus, after this system is designed, the users will be someone who has no knowledge in access, so i need to create a user-friendly system for them to use.
My questions is:since the data is always cumulative number, if I imported current excel file into access, when the next month comes, how to update the new data into excel. p.s. EXP. Mike's sale volume is different each month, and with the access system, for that column, it will be a cumulative number, like the total from the month of November to this month. how do i achieve this kind of update/import goal?I tried to link the excel to access, but by doing that, I will not be able to set relationship or change the attributes of any data type in access.

I have a main form where the user chooses a BoxID. There is a subform on this main form that has a relationship between BoxID on the main form and subform. The users are entering data in the subform and when they have entered 10 lines of info I have a message that tells them to start a new box (I could not work out how to do it any other way as I lack VB skills). The user closes the form or clicks add new record to create a new box. If I view the previous record there should only be 10 lines of information in the subform but there are 11 as it takes the blank line as a new record....

I am not sure whether this is a problem with MS Access, Visual Basic or Windows.
I have taken over supporting & developing an MS Access 2000 DB for a small charity & am not an Access expert or a programmer. The Application includes processing to create, amend & store retrieve standard letters based on a Word document called MyMerge.doc. The operating systems is Windows XP for the PCs with a MS Server 2003.
Each letter is allocated a number ‘CallID’ which is used to retrieve the letters later. The letter text is in MessageC.
The VB code to store the letters (Save As) is
Dim strTest As String, db As DAO.Database
Dim td As DAO.TableDef
Set db = CurrentDb
For Each td In db.TableDefs
If Len(td.Connect) > 0 Then MessageE = Mid(Left(td.Connect, InStrRev(td.Connect, "") - 1), 11)
GoTo jumpout
Next
jumpout:
MessageC = "%fa" & MessageE & "Db Letters" & MessageC & " " & (CStr(Forms!Contacts![PostalCode])) & " " & Trim(DLookup("[TitleType]", "Title Types", "[TitleTypeID] = Forms!Contacts![TitleTypeID]") & " " & Forms!Contacts![FirstName] & " " & Forms!Contacts![LastName])
objWord.Application.Activate
SendKeys MessageC
The VB code to retrieve the letters is
Dim MessageE As String, db As DAO.Database
Dim td As DAO.TableDef
Set db = CurrentDb
For Each td In db.TableDefs
If Len(td.Connect) > 0 Then MessageE = Mid(Left(td.Connect, InStrRev(td.Connect, "") - 1), 11)
GoTo jumpout
Next
jumpout:
Dim WordApp As Word.Application
Set WordApp = CreateObject("Word.Application")
WordApp.Visible = True
WordApp.Application.Activate
MessageE = "%fo" & MessageE & "Db Letters*" & CallID & "*.doc"
SendKeys MessageE
Set WordApp = Nothing
GoTo Exit_Command53_Click
The success rate varies from PC to PC and user to user. It will work with one letter and not the next. It is very difficult to identify a pattern. When the Save As does not offer the expected name & path, the Application (or operating system?) offers to save ‘MyMerge’ to the user’s My Documents folder.
In that case I tell the users to correct the path themselves and save the document under the CallID. Theoretically, retrieval should work since this uses the CallID and wild cards. Sometimes it does but often it will instead retrieve a document in the user’s My Documents folder. If it does go to the right folder, you sometimes have to replace the last wild card with ‘.doc’. I have tried replacing the last wild card in the VB code with ‘.doc’ but this does not work!
Finally, I alone get the message ‘Save failed due to out of memory or disk space’, neither of which is true. This makes it very difficult to continue investigating the problem. If I use a copy of the DB on my hard drive rather than the network I can save but not retrieve.
