Access :: Calculated Controls

Continuous Form W/ Calculated Controls

Jun 18, 2005

I am creating a continuous form where each record has a couple calculated controls. The problem is, as you scroll down through the records, the computer hasn't performed the calculations yet. It only starts to perform them once they are visible on the screen. So the result is blank fields for about 1 or 2 seconds every time you use the vertical scrollbar until they all get populated. Is there any way to get access to populate all the calculated text boxes when it is loaded, like a report is? I have played around with not using a continous form but rather creating a form with MANY text boxes on it that are filled with a loop. It works and all calculations are performed prior to displaying it on screen its just tricky to work with in a realistic situation and I figured their must be a better way.

Thanks for your help!

Forms :: Plus Signs In Calculated Controls / Fields

Jan 30, 2014

Why can't I ever get these to work properly? I want to use them to ignore null fields so that I won't get the punctuation but it isn't working.

Here is what I have but the commas still show up:

=IIf([Status]=1,(+[MailBoxOrPOBox]) & (+", "+([CompanyLocID].[Column](2))) & (+" ,"+([CompanyLocID].[Column](3))),"")

is there a better way than trying to use these + signs??

Forms :: Calculated Controls Based On Weekday In Form

Sep 18, 2013

Here is the basic info:

Table has Checkbox column
BusinessDate column (mm/dd/yyyy format)
OrderTotal column (in dollars)
There are others but these are the relevant ones

In the header of the form I have a calculated control box with the following control:

=Sum(Abs(nz([Checkbox],0))*nz([OrderTotal],0)),0)

Which works just fine. The user is presented with a list of all the orders from this table in the form. They check the checkboxes and the control in the header shows the total of the records checked. I need to make 7 of these calculated controls, one for each day of the week. Is this possible? This way the user can see the order totals for each day of the week they have selected.

I tried:
=IIf(Weekday([BusinessDate])=2,Sum(Abs(nz([Pull],0))*nz([OrderTotal],0)),0)

but it still sums up the whole week as the expression holds true.I do not know VB, and I'm sure there is a really neat and easy way to do it in there. I just don't know how.

Basing A Calculated Field On Another Calculated Field

Apr 12, 2006

My query contains two calculated fields [TaxSavings1] and [TaxSavings2], which are based on some currency and number-type fields in one of my underlying tables.

I just created another field in my query which looks like: [TaxSavings1]+[TaxSavings2]. Instead of adding the two fields, it actually lumps the two numbers together. For example, if [TaxSavings1] =135 and [TaxSavings2]=30.25, it will give me: 13530.25. I need it just to simply add, i.e. answer of 165.25.

Does anyone know how to correct this? Thanks in advance.

:confused:

Too Many Controls??

May 11, 2005

I have a form in my Access database that after trying to add another field to it today, I get the error "Microsoft Access can't create any more controls on this form or report."

I'm guessing I reached some type of limit that I was not aware of. How can I get around this?

Tab Controls

Jan 27, 2005

Is it possible to put a tab control on a page of a tab control?

And if so, how?

Everytime I try to fix another tab control on an already existing tab control, it places it on the form, not the control.

Nested Tab Controls

Oct 3, 2005

I have placed a tab control within a tab control (which I have done before). The problem is that the sub tab control appears on every page of the main tab form (encountered this before). I fixed it in the past by placing code on the on open event to make the sub tab control not visible unless the appropriate tab is selected. That worked fine.

I have tried this in the new program and find that when I set the value of the main tab form to 4 (the page index of the tab) the sub tab form will not display at all. However if I set it to zero it will display regardless of which tab is selected. Confusion has now set in :confused: . Any thoughts out there on what I have done incorrectly.

[/CODE]Private Sub Form_Open(Cancel As Integer)

'Me.OrderBy = "RankNo desc"
'Me.OrderByOn = True
If TabCtl44.Value = 4 Then
TabCtl144.Visible = True
Else
TabCtl144.Visible = False
End If
End Sub[CODE]

Creating A Map With Some Controls In It

Jan 28, 2005

I wanna know if it's possible to use an access 2002 form to create some controls(icons) on top of a picture (a map) so that i can click those icons to display some info. The trick part is that those icons positions are generated by x,y coordinates from the db itself. Plus a zooming control wold be a plus...

So what are your opinions on my little project.

Thank you all in advance.

Is It Possible To Group Controls?

Apr 19, 2005

Hi,

I have a pretty standard form to enter data about contracts. Depending on the type of contract, the user will answer a yes/no type question, and the result will determine what set of information needs to be entered next. Since the variables are grouped intrinsically, I would like to make them visible or not depending on what is necessary. I know how to do this with just one control, but not several at a time. Is there a way to treat them as a group, and have the form make the group appear/disappear as needed, or do I have to list out each control everytime i need to do this? Any help would be much appreciated.

Active X Controls

May 3, 2005

I have application made in MS Access 2000

I got crazy with one Active X Control on one PC. On every other PC works fine but on this one I have error "Object is missing or does not exist".

I tried delete - copy - paste couple times, unregister and register control couple time, but error is still there.

Reference looks fine, I put control on the form and everything looks great.
I tried delete control from the form and put again.

When I try to assign some data to the control I have error "Object is missing or does not exists".

It's look like my Access programm see just as read only or something like that.

Does anybody have idea why my Active X Control does not work on this PC?

Calendar Controls

May 18, 2005

I am currently using a popup Calendar in Access "Calendar Control 9". I mousedown on a field and the Calendar pops-up. I select the date and it populates field1. So far, so good. After I select the date I need I would like for field2 to populate with a date that is exactly six months out from the date I selected for field1. Any suggestions.
I hope this can be done as it would help immensely.

Form Controls

May 28, 2005

Hi guys,

please give me some directions.

Recently I designed a form with several controls including both TextBox and Combox. Before I submit data by clicking the button, I use VBA to validate the values of those controls (textbox and combox). If the value is not valid, the system will eject a msgbox and automatically set the focus on that component. In order to tidy the code, I use a GoTo statement, which refers to a group of code to display the message due to the value of parameters

But it seems VBA doesn't recongize the control I set through the parameter.

The code as the following:

private function validation () as boolean

Dim ErrorMessage as string
Dim ErrorComponent as String

......
ErrorMessage="Please select the shop Name"
ErrorComponent="ShopName" // ShopNameis a combox

GoTo ExitFunction
.....

......
ErrorMessage="Please set the start date"
ErrorComponent="StartDate" // StartDate is a Textbox
GoTo ExitFunction
.....

ExitFunction:
msgResult = MsgBox(ErrorMessage, vbOKOnly, "Error Message")
Me(ErrorComponent).SetFocus
validation = False
Exit Function

=============

As I tested for seveal time, I'm sure there is something wrong with
"
msgResult = MsgBox(ErrorMessage, vbOKOnly, "Error Message")
Me(ErrorComponent).SetFocus
"

but how can I fix it?

Many Thanks

Tab Controls - Two Forms

Jun 2, 2005

Hello,

I want to use a tab form where the user can click add, search, and edit records all from 3 tabs. The problem is I only want to be able to add data on one form, edit data on another, and just read only on the search. This seems to cause a dilemma, how can I specifiy them to add, edit, and read only on one form using tabs?

Question About Tab Controls

Dec 15, 2005

In my program I have a tab control with three tabs in it, how can I tell which tab currently has focus (which tab is activated) in VB? I checked all the properties of the tabs, and there's no GetFocus or Value or anything like that, so how do I do it?

Form With Two Tab Controls

Aug 29, 2006

I am new to Access and have not used VBA.

I have searched the forum on this, but I can't find an example of this problem.

I have a data entry form with a two-page tab control. One is for company info and the other for contact info. The recordsource is a query based on the two tables. Initially I had the page set up as a rather large form with a subform and decided to convert to the cleaner looking tab control (I used copy and paste to transfer the controls).

This form worked initially, but now I have changed some setting so that it doesn't work anymore: I can enter data properly on the first tab, but not on the second.

I have tried changing the various form properties but I must be missing something obvious. All my tab-less forms work the way I expect them to.

What I don't understand is why one tab works and not the other.

Tab Controls And Subforms

Aug 25, 2004

So I swear what I want to do isn't that difficult....ok so I can't get it to work, but I'm sure one of you gurus out there can. I hope =) At the very least tell me if it�s possible to do.

I have a form (Edit Expert) on this form is a combo box with a list of all the experts names. Below is a tab control with 2 tabs. Each tab has a subform on it with different info pertaining to experts. (contact info and education) what I want to happen is that when someone selects an expert, I want that experts info to be populated into the subforms. I have tried a macros (findExpert) that is attached to the after update property of the combo box. When there isn�t a tab control on the form and there is only one form, it works great, with tab control it says my filter isn�t based on a table or query and to use selectObject. However I have no idea what object to select. I have read the word doc that is floating around the forum about the syntax for main/subforms, but have gone in circles. However I am reasonably sure that that is were my problem is. I need to tell access to apply the filter to the subform on the tab control.

I tried to zip my db, but no matter what i do it's too big, so i hope this is enough info for you to go on. Please let me know if you need more information. Thanks a billion for your time and effort!! - me

Hiding Controls

Jan 22, 2005

I know this was mentioned and dealt with in another post, but I can't seem to find it.
Basically, I have a couple of text boxes that I would like to hide, unless told to be visible by a command button.

I'm trying to do this to save space on the form.

Someone a while back had mentioned setting the height of the control to zero and also setting the control to canGrow.
I tried this on a particular field and it didn't seem to work.

Any ideas would be a total help. Thanks all.

Help With The Controls Collection

Feb 14, 2005

Scenario:
I have a form that allows the user to enter various parameters to build a dynamic query behind the scenes. There are 'flavors' to this query process. I have a combo box from which the user selects the query type, and then I want only the proper controls to display to support the query the user chose. I have attempted this using the following code:
Code:Dim ctrl as Control Select Case mdc_cboSelectChgType.ValueCase 1 'Cust Dist - AddFor Each ctrl In Me.ControlsIf InStr(ctrl.Tag, "mdc_ca") Thenctrl.VisibleEnd IfNext ctrlCase 2 'Cust Dist - Modify Case 3 'Cust Dist - Delete Case 4 'Pending Dist - Add Case 5 'Pending Dist - Modify Case 6 'Pending Dist - DeleteEnd Select
Each Case statement would be built out similar to that in Case 1. I use distinct values in the control's Tag property to determine which controls to perform the operations on.

The problem is, however, that the ctrl.Visible throws an error: Object doesn't support this property or method.

Any suggestions for how to get around this? I'm stumped...I really thought this was going to work well....

Thanks!

Tab Controls Or Pages

May 26, 2006

Hello,

I have a form with a lot of controls. To make it much more clear for users, I was thinking of adding tab controls or page breakes.

I have placed a tab control with two pages on my form and tried to move the existing controls on the required page but of course the control will show on all the pages.

Is there a way to bypass this without having to create a new form and placing controls one at the time?

Thanks

Collection On Controls!!

Oct 19, 2006

I have 17 textboxes in my form and I want to make them disabled on a click of a button. But all this will take a lot of code writing, 17 names.enabled=false....

Is there a way to make a collection of all the 17 textboxes, like "controlsTEXT" in which I can add all of them at once and can disable all of them just by one statement like this...

controlsTEXT.enabled=false

Is this possible? or is there an alternative??

Using ActiveX Controls In MsAccess

Feb 1, 2006

I need to use various activeX controls in MsAccess2003. I downloaded a few activeX controls but I am having a problem with licensing. I registered the controls and the registration succeeded but when I try to add this ActiveX control on a form in MSAccess, I get the message that I don't have the license required to use this ActiveX control and that I should obtain the appropriate licence from the company that provides the licenced OLE object or ActiveX control. Any ideas on how to overcome this problem?
