Dataset With Wizard Could Not Get Column Information
Jun 5, 2011
i tried creating a dataset using the myodbc driver 5.1 (which im sure is correctly typed in because that is the exact same connection string i used for data manipulation within my app.now, im stuck. i cannot generate any reports because the dataset i created can not return any field information w/c is confusing because it displays the names of the tables from the database. is there any way i can import all the data i need to my reports programatically??

I made a dataset using bindingsouece and wizard.Later I deleted it from my form, from the list below.When I needed to make dataset with same name, it gave error that dataset name is invalid as it already exists.Why is this and where do I need to delete it to be able to use the same name again?

things look good till I reach the Bind Commands to Existing Stored procedures page of the wizard and I select my target spproc (rpt_IPR_...) then I hit the finish button and see the message: invalid object name '#TmpResults' now the dataset seems to setup correctly but was wondering why we are getting this message and should I be concerned. The same proc in Access had no issues. [Code]
Because we where not seeing info on the spproc parms we began to suspect that the query made by the IDE to get metadata was failing and that indeed is the case. (we also switch to non-production database to reproduce the issue)after some great SQL debugging from Kevin Currier here at Mindsolve the problem seems to be the SET FMTONLY OFF; SET FMTONLY ON; that the framework is using to get metadata info for the [Code]

I'm writing a help application for the Customer support team at my company to help agents ask better questions when customers report problems. In it, I've got a SQL database that contains all the products, topics, and questions. The layout is similar to the following:
Products Table:
Product_ID Product Name:
Topics Table:
Topic_ID Product_ID Topic
[code]....
I don't know if I'm making myself clear, but I basically need to do the equivalent to the following SQL statement: "SELECT PRODUCT_ID FROM Products WHERE PRODUCT_Name = LstProducts.SelectedValue"

I started a vb form project and tried to add a data adapter and dataset to the project. Using the "Add new data source" wizard,
I get the error: "Could not get type information for ...dataset" I have tested this with two dB's and get the same error each time. One was the master db and the other was a dB that is custom. The stored Proc's are very simple, the first I tried was
Select name from Sysdatabases;
The other was one that had worked in VS2003 in another project.
VS2005 Pro, VB project on Windows XP sp2, SQL 2000 sp4 on a windows 2003sp1 enterprise server.

So I have a form that uses a datagrid with checkbox selections for multiple (read as many!) items.When I click a button labeled "Save to file", all the information on the form, to include the values of the selected datagrid items are then saved to a database. It works great most of the time.However, I have found that if I select more than 3 items in the datagrid, I get an error pointing to the data set and data adapter stating "OleDbException was unhandled - The field is too small to accept the amount of data you attempted to add.Try inserting or pasting less data".The code it points to is:
da.update(ds, "TrainingRecords")
In the dataset, I have tried to change the max length of the associated field.It was set at 255, and as long as I stay under that, I seem to be fine. But if I go over it, I get the error. I can change the design I guess to make it less wordy and therefore store less data, but is there an easier way?

When I use a command such as:
Me
.TableAdapter.Fill(Me.SomeDataSet.Table)
I am going out to the database, gathering the requested information and filling the dataset. Therefore, everytime I add a query to a table adapter, it is also going to the database to get the information. So, my question is, how do I fill a table in a data set with all the records in the database table and then, filter the information I've already collected in the dataset without going back out to the database again?

My application reads information from an Excel spreadsheet into a DataSet (ds1) which is then filtered into another DataSet (ds2) based on user-specified criteria. The information is basically telephone call logs that reflects when a phone call was made,what extension it was made one, how long the call was, what number was called, etc.When the user's "search" criteria is matched in ds1 above, the application adds the number called to a ListBox on the form. When the ListBox Item is selected, additional information (call duration and such) is displayed to the right of the ListBox. My problem is that a single phone number could have been called multiple times on an extension within the date range the user specifies and for each occurrence of that number in the ListBox, the "expanded" info only reflects the information for the 1st call to that number listed in the DataSet.
The only unique identifier I have is the DateTime field for the row (as this goes up to the second). I thought about putting it into the ListBox item, but I'd prefer that this date not be visible until the user selects the ListBox item to view the details for that call. [code]

I have a form that has many controls. My next task is to populate the phone number (MaskedTextBox) and phone number type (ComboBox) when the cursor has lost focus from a ComboBox that has auto complete functionality. I have tried to do it and when the cursor leaves focus, the other controls are not populated. Nothing happens. I do not get any errors either. Screen shot attached for the form and I am also using a stored procedure to do this. There are two tables in question here. A client table that the name and phone number and then the second table that has the phone number type (cell, work, home, etc).There is an FK relationship between the two.
This is my stored procedure. It is called sp_GetClientInfoByName.
vb
CREATE PROCEDURE sp_GetClientInfoByName

I want to be able to get the table structure / design / column information from an access database. I have created a post in the Database/Access section with no luck, here, but I am wondering if I could achieve this through vb (2008 express edition) rather than the access sql query itself. My overall goal is to compare one DB structure with another, an integrity check if you will.

I have a dataset with a number of data columns, due to sizing issues I've updated a number of the varchar columns from say VARCHAR(20) to VARCHAR(50).I'd like the DataTable to automatically grab the new column information, is this possible? I'd rather not go through each column in the table and update the length.

Could not get column information for database object named 'COPYtblMHPuse' This is for any table I try to add.

I am making a combobox from my data source. Basically, This is a projects form and the user needs to select the the primary contact which is contrained by the customer id (GETbyCustomerID) set in another field. I have it working... mostly except the combobox only displays the contact ID which is completely useless to the user. I need to know how to display the First and Last name (both are seperate columns in the table).

I'm making my own ID field (highest number + 1) and using it when I insert a row into my tableadapter, and I've tried two ways...
Ordering my dataset by ID descending and picking the first row does nothing for me.
I've tried building a datatable and ordering it descending and choosing the first row. This works great until you get to 10... Then it counts 1, 10, 2, 3, 4...
How can I make a textbox, label, etc be the next ascending number in my column Highest Number + 1?

it's possibly to bind the values in a combobox to a column in a dataset? If so, how would I go about doing it? For example, If I have a column named 'Names' in a DataSet, each comboBox item would be a name from that column.(There will only me at maximum, 10 entries)
