View 2 RepliesMove The File Showed In A Textbox From A Directory To Another One?
Dec 30, 2011I want to move the file showed in a textbox from a directory to another one. The file showed in a textbox is randomly determined, but once is showed, I want that after press a button it is moved to another directory.
I know the instruction to move files is:
My.Computer.FileSystem.MoveFile("C:TestDir1 est.txt", _
"C:TestDir2 est.txt")
But which would be the code for a "dynamic file" depending if this file is showed in a textbox?

Dec 5, 2010I have to turn this program in TOMORROW! I can't seem to figure out how to do this section. If someone I can do the second part.I have two text files, one is a single dimensional array, and one is a two dimensional array. One titled "Months.txt" and the other "Rain.txt".The problem is I have to read those into an array, and then after that, use a query to pull the information and display it into a data grid view style box.The problem I'm facing is when I pull the "Months.txt" text file, which has the months in order from January....December, and try to display it in the data grid it puts the length of the names of the months, not the actual months. me on this matter? I've tried to no avail. Also, how would you add all of the numbers in a single row of a two-dimensional array to give a total to display in the data grid? Also, the column?

View 3 RepliesHow To Stop Controls From Updating With Data
Nov 1, 2010I have a form with many controls that are binded to a datasource. when some of these values change, they impact aspects of the form itself like the backgroud color or the title. There is a filter applied to it so it only displays certain records (this is important).when I change something and save the data I need to update the filter to show all the previous records plus the current one.All that works great, but the problem is: saving the data or changing the filter makes the controls take a new value based on the new record and go through the subs that each one have to modify the aspect of the form. This happens because if I save the data first, then the current record does not conform to the filter and all the data in the form changes, or if I change the filter first, we go to the first record of the set.
After that I return to the correct record and everything looks fine, but going to all the changes makes the app halt for a moment.Is there a way that I can stop the controls in the form form updating to their binding data while saving or changing the filter in the bindingsource?

Insert Data From Form Controls Into A SQL Database ?
Nov 14, 2009I have a form with a series of text boxes to accept user input and a button that should basically run an INSERT statement to a SQL database.I'm baffled at why I cannot figure out how to code this. All of the samples posted on the web are for VB 2005/.NET and the syntax is definitely different in 2008 because attempting to copy+paste to just test some of their source is just littered with errors.

View 3 RepliesBound Data Controls - Access ContactID?
Jan 17, 2012I have a few bound data controls on a form. However, there are certain data fields in the same table from which this data is coming from which I would like to be able to access in memory but which is not bound to a control. I have tried looking through the properties of my datanavigator, my dataadapter and my databindingsource and can't seem to find out how to sort this.
In simple terms, I have a data navigator to iterate through various fields in my dataset. I want to be able to access to the contactID of the currently visible / selected contact. The contact ID exists in the data source but I do not want to show it, just access it. How do I do so without issuing a manual SQL call to the database again?
Data Display - Using Tab Controls With Textboxes For Each Item
Oct 29, 2011I am building an inventory program. One of my forms shows the store info. It will also have a section that shows all the equipment we keep track of at that store. I am currently trying to set it up by using tab controls with textboxes for each item. The code seems ugly and sloppy and I just don't like the interface. I am looking for ideas on a better way to do this. I know I could use a datagridview, but there is lots of data and I don't think there would be enough room for it.
Here is the code I have so far.
Private Sub GetTabData(ByVal StoreNumber As String)
Dim dt As New DataTable
'DSAlrm.Reset()
Dim DaAlrm As New SqlDataAdapter
Dim MyConnection As SqlConnection

Eg;Me.txtCode.DataBindings.Add(New System.Windows.Forms.Binding("Text", bsForm, "ToolCode", True)) (bsForm is the binding source)This works well except if the form control is hidden (I have a couple controls on the form that hold Record ID and Version numbers that the user doesn't need to see). Databinding doesn't seem to work reliably for hidden controls.

Using Data Binding Controls To Add Records To DataSet
May 2, 2011I need to add rows to a DataSet using databound controls in VB.net. I've set up the data bindings themselves, they're bound the the correct controls, and the BindingSource uses the correct DataSet. The DataSet is filled from the DataAdapter correctly, and the binding source works, as the navigation controls all work fine. How do I use the controls to add new data to the DataSet? I guess there must be some kind of end-edit involved which would enable me to insert, update and delete records in the DataSet (as you would use with DataGridViews)
View 1 RepliesValidating Controls Within (WinForm) After Data Populated
Mar 18, 2011I have a form with a datarepeater that contains various controls (i.e. datetimepickers, text boxes, combobox) that are populated via a binding source. I also have other controls on the form that are not part of the data repeater. I would like to force validating all controls after the data is populated. I have successfully forced validating the non-datarepeater controls using Me.ValidateChildren() at the end of my load event. However, it does not fire the validating events for the controls within the data repeater. I have unsuccessfully tried many different attempts to set and move focus within the datarepeater controls trying to get the validating events kicked off. I am not sure where would be the best place (e.g. in drawItem? in ItemCloned?) to place the code and what it should be exactly.
Here was my latest attempt:
Private Sub DataRepeater1_DrawItem(ByVal sender As Object, ByVal e As Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs) _
Handles DataRepeater1.DrawItem
For i = 0 To e.DataRepeaterItem.Controls.Count - 1
e.DataRepeaterItem.Controls.Item(i).Focus()
e.DataRepeaterItem.Controls.Item(0).Focus()
Next
I successfully handled the validating events in the data repeater caused by user input errors. However, I have the unusual situation that the data coming into my form is already bad for some of the controls. The purpose of the form is to validate the data coming in to it and from user-input. I am newbie with vb.net.
VS 2010 Data-bound Controls Validation?
Aug 24, 2011I'm currently working on a data entry application in VB.NET and I'm using data-bound controls by simply dragging the table from the Data Sources window onto the form. It's my first time doing this, but this will save me quite a bit of time since this table has plenty of fieldsAnyway, my problem is that when I enter an invalid value in a textbox and then delete the text it won't let me select other controls or even close the form!
For example, say I have an Age field in the DB, which is an int and I mistakenly type "," on its textbox. Then I decide I actually want to leave that field blank (considering it allows nulls) so I just delete all of the textbox's contents, after doing so, I'm not able to switch focus to another control or close the form.
