Access2002 Charts: Data Limits, How To Break?
Apr 3, 2006
The BIG problem is this.
I need a basic string graph over time recieved from a cross tab query. The data points all come in fine, but the "strings" / lines connecting the points do not show up.
I believe the reason is because there are just too many records.
I culled the data down using a vba loop to only show 1 stop per minute. (BTW, is there a way to do this using only SQL?) I now show all record points, but still do not show the lines between points. Some of the lines show up, but the more data points on the graph there are, the less the lines show up, till only one or two show.
This is an Access limitation that I'm unsure of how to get around. This really shouldn't be an issue though, because Excel handles the graph just fine EVEN BEFORE the culling of the data down to access acceptable limits. And it shows the lines between each record as well.
Does anyone know of a resolution for this?

I am trying to project how long it will take to reach the 2GB Access limit in a specific project.
My client downloads approx 250,000 records on a monthly basis. I've been provided w/ a sample Excel spreadsheet. I filled a spreadsheet w/ the max number of rows (65536 rows w/ 10 columns of data), and imported that into a new table in a new .mdb file. I copied the table 4 times, so I now have 4 tables of 65536 records each. Compacted before closing. Size was about 52MB. Assuming consistency, I calculate that the size limit would be reached in about 36 months.
262,000 records = 52 MB. 52 MB a month x 36 months = 1,872,000 MB.
Does my projection appear sound?
Thanks!

I am having trouble arranging my data from a record row into a query that will give me columns for the pivot charts that I need. My guess is that I need some sort of a complicated SQL statement, and I know almost nothing about SQL. I have expressed the problem better, and with graphics, here: http://www.olypen.com/bhardin/RGB/RGB.htm. I would love to hear the solution to this aggravating :mad: problem.

Hi.
I have a table that has 1 field called IP
it containes IP addresses as data like this.
IP
255.254.253.252
255.251.250.0
Is it possible to have a query that would break this up so it becomes a new table with 4 fields like this:
IP1 IP2 IP3 IP4
255 254 253 252
255 251 250 0
I'm a beginer in this and I could not find a way so for to break this apart correctly.
Please help.

I have a nice chart that hasd done what I wanted it too.
Now I want to make the amount of X-AXIS data variable. Typically this would be 64 points. If you look at the datasheet, I can manually set the number of points by making sure the row selector is "raised".
Now that's say there is only 16 points of data to control. I can plot that those points but the chart is still 64 points wide with no data for points 17-64.
How can I, through code, prevent points 17-64 from plotting and thereby expand the graph horizontally larger and not display those null points?
I have tried a number of things including:
objDataSheet.Row(17).Delete
Graph_Data.Range("A1:A16:)
etc...
Nothing I have tried has worked. Is what I need to do possible?
Thanks much.

Hi, okay completely new to access. I'm trying to create a chart based on a query with 1 record 8 fields. I can not figure out a way to rearrange the data into two fields 8 records.
The background is I have a hundred units, each with 8 wheels. I have a table with the following fields.
-Unit part number
-Diameter of wheel 1
-Diameter of wheel 2
-Diameter of wheel 3
-Diameter of wheel 4
-Diameter of wheel 5
-Diameter of wheel 6
-Diameter of wheel 7
-Diameter of wheel 8
So, the query tells me how many wheel diameters between a certain range, with the following fields:
- Diameter >530
- 530> Diameter >540
- 540> Diameter >550
- 550> Diameter >560
- 560> Diameter >570
- 570> Diameter >580
- 580> Diameter >590
- 590> Diameter >600
Now I want to plot the range on the x axis and # wheels in that range on the y axis of a bar chart.
Any suggestions on how I can achieve this? How do I create the diameter range as a record rather than a field?
Many thanks!!!

Hey buddays,
I have a form with a bunch of Count totals in the footer.
There are 12 different areas with a number of projects in each area. So, I'm counting the total projects, and then I'm counting the instances of an area in the area column...12 times. In the query, I have 12 different Count fields, and in the footer of the form, I have Sum([Count]) for each area and one normal Count field for Total Projects. It works fine, until I have about 11 or more text boxes summing counts. Then I get #Error for all of them.
What's the magic Access limit for form-based functions like this? What's a better/faster/sleeker way of doing this?

I want to distribute an app that provides password access for a 6 month period after which time a new password has to be issued by me to the end user for them to continue. This means that I don't lose control of the programme.
Is this possible or are then other ideas to protect the app - I have looked at upsizing to MySQL but it is way beyond me, also I have looked at splitting the app and putting the back end on FTP - but apparently this doesn't work (albeit a good idea as I don't need any other programming skills). Any solution needs to be fairly simple please.

Hey guys, I asked a question before but not sure it's the right place and was difficult to explain anyway so I'll just upload my stuff here.
Basically its a school assignment that's making me so frustrated. progress was fast with tables and forms and reports but there are a few requirements i just dont KNOW how to do, not sure what to search for it the way of google either so it's making life hard.
so requirements are:
Gold memebers can book a max 7 classes, silver 4 and bronze 2.
Members cannot book 2 classes on the same day
Classes cannot be over booked.
must make in some form or other something that displays how many classes taken and how many classes are left to each member.
I know all this stuff probably falls under some very simple functions that I'm just not using correctly or have no idea exist but I've made no progess in days and it's such a horrible feeling!
Please any help! I'm not asking you to complete my assignment I'm just asking you to shine the light my way!
ps, no code please, we havent got to that stage yet.
thanx in advance,
Joe

I have two queries combined into one query. The first query shows a sales summary by part number. No problem so far. The second query shows inventory by part number. No problem with that.
Now, I combine the queries, and get only those results that appear in BOTH queries. In other words, if there is no inventory, I do not get zero in the inventory column, the entire result for that part number is skipped.
How do I still display the results of the first query if there is no match in the second query?

Hey guys,
Was wondering, what is the recommended maximum size for Access databases? I've heard that for very large databases that oracle is preferred. Would Access be appropriate for something on the scope of 5000 records of roughly 6 text and 2 number fields? Do people ever notice performance effects on databases of that size?
Also are there any ways to help reduce the size of the database? Do you recommend change the default field sizes where appropriate and would this have a noticeable effect on a database of this size? Any other suggestions to help keep the database manageable, and functioning?
I'm basically trying to figure out if there's much to worry about here, before I start importing my data. Thanks.

I am a very new access 2003 user and would welcome advice on how to cause the parameter text within [xxxxx...etc]to occupy two lines ( i.e force a carriage return and line feed) and thereby reduce the width of the parameter input box that the user sees. Also are there limits to the number of characters that can be used. I seem to remember a figure of 50 but cannot find it again in any of the books I have.
Many Thanks
Gerry

Why is my query limiting itself to only 16 columns? when I tab right for another field, it jumps back to the first field. I have other queries with far more columns than that. My DB size is 3,400 kb.

I have a textbox called Odours, there are four buttons below the textbox btn_Cadaver, btn_Drugs, btn_Explosives and btn_Money.
On licking one of the buttons a value will be put in he textbox i.e. pressing the btn_Cadaver will put the value "Cadaver ()" in the textbox.
The reason I want this is that all of the entries must begin with either Cadaver, Drugs, Explosives or Money. The brackets are there to allow the user to put some free text between the brackets.
I have some code to set the cursor (on click) between the brackets
Code:
Me.Breed.SelStart = 9
I want to prevent the user from typing anywhere in the textbox except between the brackets.

I will try and keep this brief. I have a paragraph of text, I have to paste it into a system which allows me 75 characters in a line and 208 in a page.
I have code which creates text boxes dynamically based on the total amount of characters/208 - this gives me how many textboxes need creating. I also have code which then populates those textboxes 208 characters at a time. I now need to alter it so it puts a line break every 75 characters.
Code:
Private Sub btnsubmit_Click()
DoCmd.OpenForm "NoteForm", acDesign
Dim x As Integer
Dim ctrl As Control
Dim y As Integer
[Code] ....
So I've achieved almost what I want, I just need to amend it so it starts a new line after every 75 characters...

Hi
I'm new to forum and can't find an answer to this problem. I am using Access 2002 and have a memo field in a form that I want people to be able to type in as much text as they want. This is then displayed in a report. The form accepts the text with no problems however when I view it in the report it has been cut to 255 characters as if it is a text box. I have set the properties to 'can grow' to no avail. I have searched the MS Knowledge base for a solution with no luck. I admit I'm not an expert in Access and would really appreciate some help as I have been trying to overcome this problem for days.

I have a form with an unbound textbox. I want to be able to enter a sequence of digits and spaces (e.g., 02 950 4187); however, when I paste this into the box, I always have to delete the two spaces until the number is 9 digits long. Then it will accept the number and go look for the prize. How do I get the textbox to accept the number I paste in?

Hi all,
I want to create a 100% stacked column chart (as can be used in Excel) into a report in my database, however I cannot find it anywhere to use.
Does anyone know if it is possible to use this type of chart in Access and if so, how to do this?
Again, help would be greatly appreciated.
Thanks

First of all, thanks for any help in advance, I really appreciate it. This is my first big project in Access. I am trying to design a database for timesheets for all the departments at work. We have 21 departments with various numbers of employees in each department. At this point, I would like this database to be able to have users enter their own hours each week and print their individual report of hours worked then designated users add employees, look at previous payperiods and print out a master report as well as past reports. One pay period here is two weeks, with the days starting on Saturday, though I would like the database to keep track of one week at a time and then be able to group two weeks together to make a pay period. Each employee can work regular hours in a day and can also take up to 6 type of leave plus work overtime. So there will be 8 types of hours that could be entered. So far, I made tables for each different type of hour and created fields for each day of the week and created relationships to the employee table and pay period table. I made a form in datasheet design, but it didn't work out well. For lack of a better thought for them to enter their hours, I was going to design the form to look like this (but with spaces like a table);
Employee(fn) Employee(ln) Payperiod
Sat Sun Mon Tues Wed Thurs Frid Totals
Regular Hours
Vacation Used
Comp Used
Sick Time
Overtime
Holiday
Unpaid Leave
Paid Leave
The only thing is that I can't get the forms right and it seems like a lot of wasted space since employees will rarely take holiday, paid leave and unpaid leave. Is there a better way to design this?
I also have to take into account security. I eventually have to be concerned about departments only having access to their own records and employees within those departments only being able to access their own hours (except for designated users to do the master sheet). I haven't had any training or experience in access database security. Is there a way to limit records in a table or would I need to create a seperate database for every department?
I am attaching my table relationships in case I didn't describe this very well.
Thanks again for any help. If you need any further information, let me know.

I have a very annoying problem with my break points that I can not figure out how to fix. I have a database that when I place a break points on code it will not break the code and go into debug. I have created a very basic form with one button and the following code:
Option Compare Database
Private Sub Command0_Click()
Dim str As String
str = "this is a test"
MsgBox (str)
End Sub
The message box will pop up but the program will not stop on either on the str... line or the msgbox... line. I'm sure some how or another I turned off the debugger but I do not know how to turn it back on.
Thank you for any help.
