DB/Reporting :: The Result Of Selection Formula Must Be A Boolean
Nov 5, 2008Below is my formula for a field in my report. All fields are of value type 'Number'. When I try to save the formula it gives me error "The result of selection formula must be a boolean." Why is this? Sometimes it does not catch it as an error, but when I actually run the rwport with real data, it shows the error again. Sigh.

View 1 RepliesDisplay An Equation Prior To Solving It?
Jul 19, 2011I want to display an equation prior to solving it. Obviously in MS word etc I can use equation editor to write an equation, but I'm writing my own program.
Is there an easy way to display an equation. Obviously I could use text to write eg as text "a=b^2-3(c-d)/5" and everyone here would have little problem interpretting what I want but I want this to be accessible to 12 year old children.
Alternatively I could try and manipulate lots of text boxes one on top of the other to try and explain what I'm doing
The third alternative I thought of was to write in equation editor export the graphic and then import a graphic.
I'm sure I must be trying to reinvent the wheel - which I believe is the one thing OE programming is supposed to avoid.

Allow User To Return To The Form And See Prior Input For Editing
Jun 28, 2010I would like to develop a structure to maintain my user's text input somehow on each form to allow user to return to the form and see the prior input for potential editing. My app has four forms which accept user input and form a string for output to printer. In the eventuality that the user notes a mistake in the input after leaving the app, I would like to develop a structure to "save" the user input at the form level and allow for repopulating the text boxes with the prior user input. Make sense? I have no idea how accomplish that functionality. Maybe it's too complex for my purposes. What do the pros think?

Datagridviewcomboboxcolumn Lookup?
Feb 19, 2009I have a datagridviewcomboboxcolumn which has its .DataPropertyName set to a int field, its .DisplayMember set to a nvarchar field and its .ValueMember set to a int field on a lookup table. I have captured a dataerror which states that the control is trying to push the .DisplayMember(nvarchar) to the .DataPropertyName(int) field. When I load existing data it works fine. When I try to leave the datagridviewcomboboxcolumn after selecting a different value in it or leave it when I add a new row, I get the error. What am I doing wrong?

Handling The Lookup Values?
Mar 14, 2012i am using the LookupEdit control from DevExpress fairly heavily in my projects. It is like a combobox, but it is bound to a datasource and can display multiple columns from the datasource. A single column is identified as the "value" column and a single column is identified as the "Display" column.
I use the LookupEdit control on my forms to give users a pick-list of appropriate values for a particulat database field. Each field has its own table in the database holding said values, commonly referred to as a lookup table, and each lookup table is used as the datasource for each paired LookupEdit control. Of course when a form is being filled-in by the user this works great. And it works good when the user opens a saved record into the form and I set the EditValue of the LookupEdit based on the value stored in the database. Pretty basic stuff right?
Now here is the problem... Let's say a lookup value is no longer an appropriate entry and so it is removed from the lookup table. Say I sell cars and one of the fields in the Cars table is Color. And I have a lookup table called CarColors and the selections are: Black, White, Red, and Silver. Now let's say we sold some Red cars in the past, but now we no longer carry Red as an option and we probably never will. So I remove "Red" from my lookup table, and now when I load an old Order into my form the LookupEdit for Car Color value now shows NULL. What is the best way to handle this situation? ProcessNewValue? Set NullText property? Use a bit field in my lookup table for IsActive, and set to FALSE for Red instead of deleting it?
Obviuosly I want to retain the historical values while maintaining a currently valid lookup list. And I know this question goes deeper as there are probably database design considerations like whether or not to put a constraint on the foreign key relationship between the lookup and child table, etc... I should also mentioin I am using LookupEdit control rather than a ComboBox becasue a lot of my lookups have other information like Description, Sort Order, or are coded and thus require a multiple column display.
Lookup Column In Datagridview?

NetBios Name Resolution / DNS Lookup In VBA
Jul 16, 2009I have an Access 2003/2007 application that pulls computer names from my network along with their last know TCPIP address. This data is created by another application. I am trying to use the IP Adresses to install software via a push application that accepts a list of IP Addresses.My app has a history table of every comuter that has been checked to see if the software is installed. I use the Fully Qualified Domain Name to make this verification. I then populate my text file with the IP address of the computers that have not been installed.This all works well if the last know IP address is still valid for that computer.What I am trying to find is a function that I can pass the FQDN to and have it do a NetBios lookup to return the current IP Address from our DNS Servers so I can be sure that the IP addresses I am populating the text file with match the FQDNs of the computers I am trying to push the software to.I found some info on System.Managment.dll. For some reason Access will not let me add it to my library references.Does anyone know of a standard library function I can use to achive this.[code]

Sql - SSIS Lookup With Update Possible?
Sep 16, 2011I am converting a DTS update lookup to an SSIS lookup with an update query. So far it doesn't seem to work.

SQL Query in DTS:
UPDATE TABLE1 SET STAMP="TEST" WHERE (ID = ?)
In SSIS:

IS there anyway to accomplish this in SSIS with a lookup? Or is there a better way?

There are 47 fields that have to be populated and/or calculated based on two fields, the Username and a date range (this part is done). I was trying to set each of the TextBoxes equal to the SQLCommand that would return the proper value, but i am not calling it correctly. Would somebody please take look, is there something i am missing, do i need to write it in a function? I have had to use the Select statement itself in a couple of filters so I'm pretty sure that is correct, but i need help getting it to run the sqlcommand.[code]

View 1 RepliesFiltering A Combo Box Lookup On A Datagrid?
Sep 15, 2011I need some advice I have a bound datagrid and a bound combobox lookup on a form. What i want to do is filter the combo box so it only shows the items left that are not in the datagrid already.
I have managed to achieve this already.But when the program runs, and there are items displayed in the data grid the combo box items are now filtered.The program crashes as it can't display the combobox item as i have filtered them out. The program runs fine if the datagrid is empty (IE combobox items not filtered). But as soon as there is a record in the datagrid when i save the database and refresh the combo box the program falls over is the items it is looking for is not in the combo box items list.
What would a work around be. I have thought of a separate combo box that is hidden and use the datagrid combobox events to show it in the correct position.Just to be tedious the displayed item is not the stored item value

I then setup an object data source and mapped it to this class.I have a few questions as when I was doing internet searches I didn't find anyone that seemed to be doing this and yet I know lookup tables / combo boxes are common...I went with returning a list but I could have returned an IEnumerable or IQueryable. In my reading it seemed IQueryable had more functionality for linq to sql but since I am returning a simple two column list then I only need to return an IEnumerable or List. I went with a List since it's strongly typed.
