I want to add the table names from a database in sql server to a combobox with vb.net windows programming.
Its a customer accounts database where for instance I add a new Account holder which creates a new Table and when I want to view a specific account holder a want to select that account holder from a combobox that views the Table names.
[Code] my issue is that now i need two cases, first i need a query that will return the date created and modified of the table and i also need to know if its possible to query a list of table names in the database ordered by date created but that have a certain thing in their names. for example the database contains the following tables: [Code] and what i need the query to return is the tables that contain "Data", settings and employees are for the other functions of the program. so the query should return the 4 data tables in order of date created. but i have no idea how to go about doing that in the query, does anyone know how this is done?
View 6 RepliesI have a vb express 2010 program where users submit issues to different persons. The issue is emailed to teh selected persons and also saved in SQL on a server. Question is if they select multiple names from the list box to send the messsage to, how do I insert the multiple names into the SQL table? Here is the insert command I use. It will insert one name but will only do one if multiple names are selected. What am I missing?

Ive completed this code, and it enters names into the combobox, but not any of the tables that i have created. I have checked that they have been created and they have. An ideas?

VS 2010 ComboBox filtering of db table names
View 4 RepliesI am populating a combobox with a list of names that are coming from a database. I would like to get the names to show up in the combo box in alphabetical order. [code] There is also another combobox I'm populating with text from a database. (as below). However, in the database, in the column I'm reading data from, there are a few duplicate rows and then when the combobox is populated, the same text can be seen 2/3 times. What can I do or add to my existing code, that will ensure that there is no duplication shown in the combo box? [code]
View 3 RepliesI am using OledDb to create/retrieve/delete data from Access databases. At one point in the solution, I the user adds data to a new table and the table name is defined by the user. The obvious problem with this is that the user could add spaces, characters, and Access/SQL keywords that are not allowed in the table name. Later in the solution, the user should be able to identify their saved table and retrieve it. I have considered the brute force method of formatting the input to remove offending characters and then reformat for the user's view, but that seems like something I would like to avoid. I have also considered placing restrictions on the textbox with masks, key event restrictions, and checks for conflicts with keywords, but I would also like to avoid that. So, my question is, does anyone have a creative solution for identifying a table name with something like 'my name is table number *1'?

View 6 RepliesI have made a Database.mdf that contains a table that Includes 3 diffrent Column Names.
1:"ID" This one i set to an primary key and i have also made it automaticlly put a number in order to the list. Like 1,2,3,4,5 for each data added. Data Type for this is int.
2:"WordCombination" Were i enter my word combination that i want it to look for)
3."TypeofCombination" Were i enter what the program should add to what i typed in texbox1 if it contains the WordCombination.
I want my program to se if texbox1 contains any of those WordCombinations in my database. And if thats true, Then i want it to show whats in the TypeofCombination + the text in texbox1 in texbox2. If i enter "What do you want ?" in Textbox1 i want the program to find that "What do you want ?" contains "you want" like in ID:1 WordCombination:you want. So becuse this is ture it should enter TypeofCombination in this case "Question:" + what i entered in Textbox1 to show in Textbox2.So if i write "What do you want ?" and click start. Textbox2 should show "Question: What do you want ?" If i Write "My name is Jake" and click start. Textbox2 should show "Answer: My name is Jake".If I Write "hello you Hi there Jacob" and click start. Textbox2 should show "Greeting: hello you Hi there Jacob".And i Should be able to add and delete Word Combinations Without having to change the program.

The SQL statements look like this.

Dim Username As String = ComboBoxUsername.Text
Dim PW As String = TextBoxPassword.Text()
Dim MR As Boolean = CheckBox1.Checked[code].....
I am getting error messages telling me "Syntax error in INSERT INTO statement.If I try a query with just the Username and Password which are both text then it works fine.If I try a query with just one of the Boolean fields it works fine.If I try both Boolean fields or the text fields and one Boolean field then I get errors.

View 6 RepliesI am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields:
QuestionNumber (unique integer key)
QuestionText
QuestionType
In my SQL Server database I created a Table called "QUESTION" with the same fields.
QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

View 6 Repliestrying to figure out out to make a combo box re-populate itself with values from its data bindings from an Access database.
I have my bindings in the combo box, and it pulls the right column from my table, and returns the proper value to a different table. Everything saves properly to all of the tables, but what i am trying to accomplish here is this...
I have a combo box, it is populated with a database column of "G/L codes" (by the way that is not the column name) the combo box shows these values without problem.
These codes exist in a table that is editable (basically so the user can add a G/L code to the list if one is missing), a button is supplied that opens a new form, which contains DB related text boxes, and a data binding navigator to look through the data base records, save, add new records, etc. When this form is loaded, the user can add a new record, save the info, and then close this form, which brings us back to the main form where the combo box is located that is populated with the values of this G/L code table, what I am trying to get working is updating this combo box now that a new G/L code has been added.
I have been looking for a solution for days, tried many forums, read all posts on this site that had a keyword of "combo box" and I can still find nothing. I have tried many code samples such as...
Private Sub Repopulate()
Me.G_L_Code___DescriptionComboBox.DataSource = Me.Db1DataSet.GLCodes
Me.G_L_Code___DescriptionComboBox.DisplayMember = "Combined"
Me.G_L_Code___DescriptionComboBox.ValueMember = "Combined"
Me.G_L_Code___DescriptionComboBox.Refresh()
End Sub
have tried calling this when the combo box gets focus in the attempt to update the combo box every time it is selected.
Have tried reloading the table adapter as well when the combo box takes focus with the following
Private Sub G_L_Code___DescriptionComboBox_TakeFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles G_L_Code___DescriptionComboBox.GotFocus
'TODO: This line of code loads data into the 'Db1DataSet.GLCodes' table. You can move, or remove it, as needed.
Me.GLCodesTableAdapter.Fill(Me.Db1DataSet.GLCodes)
End Sub
Honestly I'm at wits end trying to get this combo box to repopulate its values from the database. I don't get any error codes when running either, all my attempts simply do nothing

I want to track changes in an application. So I've made a copy of the main table in that application, and am accessing both tables in the application using two separate datasets.
My plan was to use the HasChanges method of the main DataSet to get changed rows and then insert those into the copy table. When I run the code I get an error:
A first chance exception of type 'System.InvalidCastException' occurred in MyApp.exe
Unable to cast object of type 'MainDataTable' to type 'MainAuditDataTable'.
Here's the code:
If Me.DataSet3.HasChanges Then
' 'look for each row that has changes, not new rows
' 'insert that row into the auditing table

I have multiple file upload boxes on a form in my mvc3 application. Request.Files shows 3 files when I put a break point in the below function and look at it.. Problem is other than coding a counter and using a select case I dont see a way to handle saving each file name to the database column it belongs to... Is there away to assign the variable on the fly I guess you could say So that the foreach loop would drop the file in the correct column. Ie handoutFile1, handoutFile2 , handoutFile3, Etc. As it stands the below will overwrite the filename in handoutfile1 every time the loop is gone through. I thought about throwing a counter in the loop and just put a select case on it to assign the db column based on the counter number. Seems like a cheap work around though. [Code]
