NetBios Name Resolution / DNS Lookup In VBA
Jul 16, 2009
I 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]

1. Is there anyway to make an application look as though it has been set to a screen resolution of 1024 x 768 when the true resolution different?
2. I am developing my app using a widescreen monitor. What dimensions does the form need to be set to so that it looks exactly the same on a normal & widescreen monitor?

I have a very high screen resolution on my laptop: 1400x1050.My colleague tried it out on his laptop (which had lesser resolution), and the application did not fit on his laptop. The buttons were dragging out of the screen space.So, I want my application to automatically resize/adjust based upon the screen resolution.I don't want to use Maximized screen option and don't want to change user's pc settings.Unfortunatly I am not using Table Layout panel.

Can we set the windows form resolution according to pc screen resolution and even the control should be adjusted...
eg.
My screen resolution is 1366 X 768
and my form size is 1254, 709....but I want it so set according to the screen and it will be dynamic...
if I transfer my project to some other pc with lower or higher resolution it should be adjusted....
and suppose I have few controls on the form...will that also be adjusted??

I 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?

Simple Code lookup to get Description I have a static list of Street Type Abbreviations and their associated Street Type Descriptions: RD to Road. I have the complete list needed. There are 37 elements in the list - 37 Street Type Abbreviations with their associated Descriptions. The lookup will only happen once. The input lookup field is in a single field: stType.

i 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.

I have a datagridview control on a form that is filled programatically (dataadapter, dataset ) from a database table (access).
Some of the columns in this table are foreign keys to other tables. Is it possible to have these
columns as combo box columns so the values can be selected directly from the other tables?

I am converting a DTS update lookup to an SSIS lookup with an update query. So far it doesn't seem to work.
OLD DTS ACTIVE X CODE:
value = DTSLookups("apple").Execute(DTSSource("ID2"))
SQL Query in DTS:
UPDATE TABLE1 SET STAMP="TEST" WHERE (ID = ?)
In SSIS:
Create a lookup, use same above query, and I get an error if I click on column: "Parameter information cannot be derived from SQL statements. Set parameter information before preparing command"
IS there anyway to accomplish this in SSIS with a lookup? Or is there a better way?

I am almost finished building my application. All the data need is being inputted from various locations. I have a form that is suppose to consolidate all this data into a specific format. 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]

i am using a third party tool "lookupedit control" which is similar to a combobox. as we type in the address bar of our browser we get the related items in the dropdown of the address bar. eg: if e type go we get all the items starting from go in the drop down of the address bar. I want to implement the same functionality for lookupedit or a combobox.

I 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 am trying to setup a lookup combo box in my web page. I was using a linq data source but I then moved my linqtosql code to it's own class library for my DAL dll (took out of app_code folder). So, I am converting the page code to be able to still have lookups driven now by a biz object.Here's what I have done in my biz layer...
Public Class KosherTypes
Public Shared Function GetKosherTypes() As List(Of KosherTypeLookup)
Dim db As New DBDataContext
[code]....
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.

I'm using VB.NET but any other known language should be fine as long as it uses basic features. My task is to create astrological compatibility chart, when two users have certain astrological sign as inputs and there is a text about those signs compatibility. for those who are unaware of astrological signs but still want to help, there are 12 signs. Each sign has different compatibility with other sign or itself. So basically i get into 12^2-12 conditions. ie. Aries with Cancer "do not match at all" so I can save one record of that issue as backwards it is the same (thus -12 at the end). Question is simple is there any other way to create this except of using 12^2-12 case issues...

I'm wondering what a best practice is for handling this.I've got a standard vendor table - with VendorId (which is PK, numeric) and a field the users call SimpleId (which is usually a name - don't let the column name of SimpleId make you think it's numeric!).I've got one datatable that comes from a data adapter that looks like this. And this already changes the table in the SQL database...SqlDataAdapter("Select VendorId, SimpleId From Vendor_T", _connection)I've got this datatable on one panel of my form with a binding navigator - and you can change the SimpleId for a vendor with this.

I've been trying to use lookup tables to display names instead of ID's in a DataGridView using a DataGridComboBoxColumn and have even copied the example shown in the Forms over Data videos produced by Microsoft but still get the following error message:System. =Argument Exception:DataGridView ComboBoxCell value is not valid..Everything was done in the designer and the problem only occurs with the DataGridView; lookups work fine using a combo box when displaying single records.Also the error message only pops up when I close the form. Prior to that all the names are displayed correctly for each record, the drop down list shows the names correctly and I can edit, add and delete rows and save all my edits with no problems. Its just when I close the form that the problem occurs.Each time I press OK in the message box the names in the combo boxes are removed, one by one.

I want to create a simple program which can convert Units of Measure (e.g inches into centimeters, milliliters, meters, feet, etc). I want to create a function which has two parameters (unit to convert from and unit to convert to) and returns a conversion value (e.g. funciton passed parameters values inch and centimeter and returns value 2.54). In terms of strategy for the least processing overhead I am exploring a few options. I guess the slowest way would be some kind of nested If/Then or Case loop, so I wanted to use something similar to a 2D table lookup in excel (where the top row and the left column (key?) would have the unit types, and the conversion values would occupy the cells in the table body). Is this possible in VB? Could I load all of this into a 2D array or something? I read a bit about hashtables and dictionaries as well, Ideally Im looking for the least processor-hungry code since this function may be called upon frequently. Ill be using other functions to perform similar lookups on other 2D tables elsewhere too (i.e. matching a value on the top row and the left column and returning the coincident cell value in the table body).

assist in the proper way to populate a value in a txtbox based on a combobox selection? I basically have a table (tblStudent) that has two fields (Range, Amt). The range records are 1-5,6-10,11-20,21-50, >50. Amt are 0 by default.
four more Tables
(tblPA,tblNY,tblNJ,tbMD) with 2 fields (pctgStud,amount) where prctgStud are
ranges (0, 1-10,11-25,26-50,51-100). Amount are 0 by default.
My form has a 5 simple comboBoxes that allows one of the ranges to be selected for each of them. I also have 5 txtBox relating to the corresponding (Amt) fields. How do I populate the textboxes with the related AMT based on the range selected from the comboBox. On a side note, I want to ultimately increment all the textbox values by one in the tables when submit is clicked.
