Nov 24, 2010
I have a database set up with 2 fields, FirstName and LastName, and i want to display both of them in a single combo box. Right now its only displaying the first name:
[
Dim dtFishermen As DataTable = objDS.Tables("fishermen")
Me.cmbFishermen.DataSource = dtFishermen

I have a table which contains a list of products for a company. They input data about how much stock they have and also the level at which they want to be reminded that they need to order new stock.
[Code]...
I want to list all the true results in a form which the user is then able to navigate through. What would be the best way to go about doing this?

[code]....I have a dialog that comes up and asks for a reason for declining the business.I don't want the code to move on after not enabling the "me" until the reason has been entered and saved into the database. Also, at that point where it says "I WANT...." I want to copy the textbox fields into a new database and then delete this entry from the database, how can I do that. I am using VS 2008 and SQL.

I am working on a timekeeping application, using Visual Basic 2008 Express edition with an Access 2000 database.The application requires the user to complete a timesheet by recording in tme and out time daily. Blank fields are perfectly frquent and perfectly legitimate.Using these lines of code it works perfectlywhen there is a time value in the database.[code]This indicates to me that the code to ignore a field containing nothing is not working

This will actually be for a WPF app but how do I filter the fields of a SFD database so that I can use expanders with listboxes that contains last names from the DB ? The expanders will have headers of the letters A to Z with last names for example in the A expander listbox all starting with A .Coding4fun

The OwnerID relates to the ID in the users table, how can I get the name of the user who's ID matches the OwnerID? I'm writing a website in ASP.net (VB).

I have a connection string set up and a data reader.I have two textboxes on my form for users to type in. One textbox (txtLogin) is a user name and the other textbox is a password (txtPwd). I'm trying to compare what a user types into those two boxes to a table in a vfp database. The table I'm trying to compare to is open about 99% of the time so I need to be able to read from it in some type of "shared" mode.
My Select statement needs to be something similar to "select * from sites where clogin = txtLogin.text and cpassword = txtPwd.text"I just don't know how to get this to work properly.

I have a problem trying to copy 3 fields on a form to a database. The reason I cannot seem to do it is that the last field asks how many copies you want to save in a combo box. So lets say the user selects 3 I need to be able to copy three sets of the same data to the database.

In one of my school assignments I am trying to count fields (that are strings) in a database and then publish them to the screen, however I can't seem to figure out how to count them.I've been trying to do something like this but I am having trouble with the bold part. I think the datatypes are the issue but if not this then what? What is a better way to try and do this?

Try

This is the line of code that has to have another 30 entries in it.

I have been tasked with writing a program for our yearly reviews. We want all of the information gathered in the form to be submitted to an access database. I have created the form and the database. I can send info to the database but it is put on a new line everytime it is submitted. I would like to check the first column of the table to see if the user login is already there. If it is there I would like to update the information. If it is not there I would like to create a new row. This seems simple, but I can not figure out how to see if the user login is already there.[code]...

I am an experienced programmer but am new to VB. To start, I am trying to create a simple database program. (My ultimate goal is writing a comprehensive database program in 6-8 months)I have created the database and bound the fields to a form.
But what I want to be able to do is add a field to the database and then also bind that new field to a textbox on the form.The new field appears on the list in the Server Explorer window (on my left) but not in the data sources window (on my right.) The data sources windows has a "refresh" option but that does not help.When I manually add a textbox and try going to DataBindings in the property window the new database field is not listed.

i'm doing a project for school which requires me to make a fully functioning database program with validation. I'm done with almost everything except a few things and that includes the database, since i don't really know how to make validation rules and masked fields.It's possible i'm guessing to in forms and such but in datagrid view?

I was wondering if it was possible to generate fields or details (they are called in IDE) of a xml tables .When you create a database than go into the Datasources and find the table you want than there is a drop down box with datagridview and details.When you select details and than drag the table over to your form ,the IDE creates or the nessiary fields to add and view the data.
If Possible ,How do I do this Using a xml file and at runtime .I have already managed to create the xml as a dataset and view it in a datagridview .But how do I create the fields for the tables .BTW the XML has Multiple tables?

I've been attempting to tinker around with connecting a MS access database to a vb 2008 app. I've successfully connected and can access the data by using the add data sources tab. But what I'm trying to do is create a form that has a (1) single line text box, (1) button, and (1)multi line text box. I enter a name in the single line text box, click the button(search db), and when the info is found, it is displayed in the multi-line text box.

I am new using Vb. I did create an app that accept general customers info, and save it into a database using the bindingsource component(I don't know how to do it with SQL from VB). Everything was fine, but adding a couple of maskedtextbox has become difficult. I don't know how to pass the value of this fields to the database. I used the following code:
phonetextbox.text = maskedtextbox.text
Leaving the original fields in the form, I see the values on them, but they never goes to the database. Is this just possible using sql command from VB?

I have finished my database using Dreamweaver ASP VBScript and Access, the only thing left is to create the searching system. My search form works fine when posting just one filed. The results page Recordset goes as follows.
Code:
I need 7 different fields on my search form, this what I did but it doesn't work.
Parameters:
Name: MMColParam
Type: Text
Value: Request.Form("Ref")
Default value: 1
Name: MMColParam
Type: Text
Value: Request.Form("New_resale")
Default value: 1
"Price" is a special one because this is a list menu with different amounts, like 50.000, 70.000, 90.000, and so one. The idea is to make this list menu post to the result page, only to display records under or equal to the given value. less or equal > than 50.000 or 70.000, etc.

how to update fields in an Access database through VB. What I'm supposed to do subtract the quantity of the daily orders from the inventory quantity. My textbook is a little bit vague at this point, because the only way it describes updating the DB is manually through the BindingSourceNavigator. I don't want to enter it manually, I want it to subtract the quantity from the orders table.
