how can I filter my datagrid view by letter..for example: if I write "m" in a textbox, every row begin with "m" appears,then I write "moh",so every row begin wiz it appears...I found a lot of methods related to dataset and binding source...but in fact I don't need such those methods... Just wanna filter it without any relation between database...(because I'm using webservice vb.net+eclipse java+access as database,so my db is related to eclipse not to vb.net)..

View 11 RepliesWhen 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?
The following code works (rows are filtered by the select expression), but then all the controls in the datarepeater are empty. When set to .DefaultView all records return and all controls have their values.

I'm writing an app for someone where I am pulling in work orders table information. The information includes: worknum, fname, lname, customername, description, etc. I do not plan to update the data in this table, only to read from it.I'd like to display a combo box for the work order numbers. The user would start typing the information for the work order in and it would autocomplete based on what's in the list. As work orders are displayed in the combo box, I want to update the data in text boxes representing the various fields.
I'm thinking rather than query the database several times, it would be a good idea to create a DataSet with information for the work orders table within the last x months then query the data from that dataset. I know there is a DataSet.Select method, but it looks like it returns the entire row. Is it possible to retrieve just a column of distinct values? For example, I'd like to do a select statement similar to this:
SELECT worknum FROM {WorkOrderDataSet} WHERE date >'{today-x}
The first part in curly brackets is meant to represent the work order dataset I create when first importing the data from Access. The second part in curly brackets will be replaced with variable data to represent a date to reference. I also don't think I'll need distinct because the workorder is unique (edit: is a primary key)Is it possible to retrieve just a column of distinct values from a DataSet with multiple columns? How do I do this?

View 9 RepliesI am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.

View 1 RepliesI am trying to make a file/drive/folder directory interface with VB. It is all working except the only thing i can't manage to make it do is to filter on more than one file type. I want to be able to filter on BMP and TIF files, i have the following code:
filterList.AddItem "*.TIF; *.BMP"
filterList.SelText = filterList.List(0)
'Apply the file type choosen to the file list displayed
filDialog.Pattern = filterList.Text
The filterList is the list box with the file type extensions and the filDialog is the list box with the files.It only filters on the first file type, so in this case TIF (no BMP), even if you swap them it only filters on the first file type.

I have found the documentation that allows me to change it in the config file, but I need to do it at runtime.
