DB/Reporting :: Which Is Bound To A Table That Includes Information About Properties?
Feb 1, 2010
I have a form which is bound to a table that includes information about properties (real estate). Each property can have a number of inspections. These inspections are included in a separate table.
I want to use the form to show the property information and a data repeater to show all the inspections for that property.I can't seem to get the data repeater to bind to the inspection table and pull only those records related to the property information table. In fact, the data repeater shows nothing.
I can get a data repeater to show all the records in the inspection table when I put the control on its own form, for testing purposes.

I 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.

I am looking for a way of automating the generation of a text document which includes a table and an image. My client has requested, however, that it be in Open Office format. I have played around with AODL for a while and have been able to create a file with the text within the table but some things are still bugging me.One such thing is column width. Another one is aligning an image.I find the problem with AODL is that it is not very intuitive to use and there are not so many examples available.

There is a connection in my program to SQL Server and there is a query which is bound to a combo box, to pull out values from the database. For some reason, I get an error message during run-time, saying that the syntax is incorrect.
Here's the query:
'The SQL Command to be executed:
projs = New SqlCommand("use " & Me.ComboBox1.Text & "''" & _
"go" & _
"select name from projects where condition = 'Y'", cnn1)
cnn1 is the name of my SQL Client connection.

I added a datagridview box to my form from the tools menue. I added some columns and would like to place a save button that allows users to save the data they put in those columns. The datagridview is not bound to a database, it is only being used for design reasons and a database is not necessary. What code can I use in the button to save the changes?

Rather than running numerous queries in Access I am trying to write a front end for a DB2 database. The Access database is getting to a size that it is causing Access 2007 to have reliability issues and frequent compacting is required. I have created the Dataset, the Table Adaptors, and the Connection String already, but when I put in a bit of code in to fill the Table Adaptors the remote connection I have to work is going crazy (chewed up about 180MB before I realised it was pulling data from work).
Before I started the project I copied the .accdb to my local PC HDD and I pointed the connection string to it, but it still looks like it is trying to pull data from the work network. If it was a small database I wouldnt be concerned but it is pulling major data every time I run it. I have only 2 out of the 4 Table Adaptors running and it didnt fill them even after 10 minutes.
Here is the code I was trying to run... Server name has been substituted for Server for obvious work reasons.
Because the tables are so large I was looking for a way to pull only the columns I need to from the tables, I tried adding .SOFT_ID to the first line of code but the TA spat the dummy message below...
Value of type 'System.Data.DataColumn' cannot be converted to Application_Name.DS_DB2Database.Server_SOFTDataTable'.
Code:
Me.TA_ServerSOFT.Fill(Me.DS_DB2Database.ServerSOFT.SOFT_ID)
Me.TA_ServerSOFT_FOUND.Fill(Me.DS_DB2Database.ServerSOFT_FOUND)
Me.TA_ServerHARD.Fill(Me.DS_DB2Database.ServerHARD)
Me.TA_ServerREF_SUP.Fill(Me.DS_DB2Database.ServerREF_SUP)
I would also like to pull just the data columns I need to speed up the query.
Note: In case youre wondering why I am not connecting directly to the DB2 database. I currently dont know where it is stored and while leveraging Access I am trying to put a level of separation between the app and the db for the time being, later I will try connect directly.

I have looked all over the web for a way to set up a VB 2008 combobox but what I have seen makes me shudder! I want to , as In Access VBA, set the recordsource/datasource for the combobox i.e. the list shown in the combobox, to the values of another table (currency) and then when the user selects one of these values to store it in the (already) bound field of the combobox (to another table). In Access of course there was a wizard for this sort of thing, but in VB 2008 looks like it is just lots of code.

I have a DataGridView that is bound to a DataSet and I allow someone to remove a row from the table and I remove the row from the set. My code looks like this:
ds.Tables(0).Rows(dgCourseList.SelectedRows(0).Index).Delete()
My problem I found is if the grid gets sorted the index of the rows no longer corresponds to the indexes in the DataSet. As a result the wrong rows get removed from the set.
Can I solve this problem with maybe having to sort the DataSet on some sort event of the DataGridView?

We are making a report (2005) of a certain time duration, for example one month. In the stored procedure we made, two parameters are given; start-date and end-date. In the report we want to place these two dates, but we can only put database fields in the report. Does someone has any idea how to put these static information into the report?

I have a DataGridView bound to a data table. I have one column where I permit updates. After I fill the table (at form load), I make an update to this column Then I attempt to update the change back to the bound table. I get the error 'Update requires a valid Updatecommand when passed dataRow collection with modified rows'. I have seen some examples on-line to define, load, and update but since I have the generated datagridview with bindings, shouldn't the update method me a simple 1-liner? [Code]

I'm, using a SQL Server table in a DataGridView and I'm having trouble adding records. I'm new to vb.net but used vb6 for a lot of years so the transition is a little difficult. For now I'm just trying to add a record using a button click but the record key which is setup as integer and to automatically increment by 1 shows as -1 after the record is created. While the data does show in the grid it is never actually posted in the table. Once created I want to select the record just entered.
Here's what I have:
' Declare
Private addedRowIndex As Integer
Code:
Dim newMessagesRow As ArcadeDataSet.messagesRow
newMessagesRow = ArcadeDataSet.messages.NewmessagesRow
newMessagesRow.movie_title = "Added Programmatically"

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code
,
Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

I am creating a small admin reporting tool that gathers certain information on some PCs. Unfortuantly the user that is running the tool doesnt have access and I cant give access to those particular machines. What I have done is created a user on these machines that can get this information.I would like to then have the reporting tool run certain parts of the code as this user so the information can be obtained, without any intervention from the user running the tool. Can I hardcode this user into the code so that it runs the code as the user?

Visual studio 2005 - vb.net..I have a user control on a form containing 15 combo boxes.All contain Y, N, and blank (for Yes, No, or blank) in the Items Collection property.Each of the combo boxes have a binding source to the same table, different fields.When you select a value Y, N, or blank for any of the fields and do a save, the values save while the application is open.Once you close and reopen, the values are gone.It appears the dataset does not recognize the change, so the values are not getting stored in the database table. Is there something I can do or put in one of the events that would identify this as a change.
