Using CheckBoxes To Identify Records Within Master File
Jun 12, 2011
I would like to bind data with a CheckBox. I am using VB 2008 Net 3.5. I want to use several checkboxes to identify records within a name $ address masterfile. Any given name can be identified in one or mre ways. For example John Smith can be an employee, a vender or a client. I have setup seven fields in my database as bits and in data sources I have labeled them as CehcekBoxes. However, I can not bind a CheckBox to a field.
I am a newbie using Visual Basic 10 (Visual Studio 2010) and I am having a hard time working with my database. I have a table, let's say, TableEmployee with Fields Name and Position. On the Position Field, some of the records there were empty.My table is displayed in a datagrid and what I want to do is to insert a code that will identify whether the record under the position field is blank/empty and if that condition is true then display a messagebox that says "the particular record is empty"
Dim curweekFolder As String curweekFolder = String.Concat("c:", curweek_date.SelectedItem) Dim preweekFolder As String preweekFolder = String.Concat("c:", preweek_date.SelectedItem)
[code]....
I first wanted to identify which files matched in filename and list those in ListBox1, the following that was suggested on this forum worked very well (I added the minus last 19 characters as they would be different).
ListBox1.Items.AddRange(curlist.Where(Function(fi) prelist.Any(Function(fi2) fi.Name.Length - 19 = fi2.Name.Length - 19 AndAlso fi.LastWriteTime = fi2.LastWriteTime AndAlso fi.Length = fi2.Length)).ToArray)Now I need to populate ListBox2 with the files that do not match in each List (of T), again without looking at the last 19 characters. So for example if the first List (of T) had A.txt, B.txt and C.txt and the second List (of T) had A.txt and B.txt then ListBox1 would have A.txt and B.txt while ListBox2 would have C.txt.
I have a dataset containing 2 tables,Customers and Contacts. Just showing the master-detail is not a problem. Problem occurs when I try to search the master table to bring in the detail table. Searching the master table shows only the master record, but not the related detail records. Adding a 'findby' query on the detail table only shows the records.url.. Normally when the master table is filled, the detail record shows in a form.
I am having a problem trying to save records in a parent / child data relation. I have to tables tblContacts & tblMember. There is a fk relation on the ContactID field. The tblContacts table is the master record. I am using a set up bound windows forms controls to do the data collection. The problem that I am having is in saving the child record. After the form is populated in both the fields and hitting the save button the items in the child record get deleted. It does add a row in the child record but only the ContactID (from the master table) and the key for the tblMember table. This program will not be using a datagrid. I did experiment with datagrids and it works well. The problem is when I try to use detail views in the form of textboxes that are bound to the bindingsource.

I can see that since the new master record incites the addition of a new row, the data is abandoned. Once there is a save done to the master / child record I can go back and modify the fields and it saves it successfully. I know I must be missing something small. I am not sure how to work around this so that the controls are read into memory and then completed in the new row. I have an example of my code:
Private Sub TblContactsBindingNavigatorSaveItem_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TblContactsBindingNavigatorSaveItem.Click Dim newMemberRow As DataRow 'To create a new row in the tblMember table
I created a dataset.xsd and it contains two table adapters and these table adapters use stored procedure for select.in my vb form, i get value in text box and then fill table using tableadapter and pass parameter to sp. Till this point everything is working fine. Now these tables have relations and i want to create relationship and show the data from child table on basis of master table. How i can do it?
Example
Me.MasterTableAdapter.Fill(Me.dataset1.spMaster, 1) --1 is parameter which is passed to sp Me. ChildTableAdapter.Fill(Me.dataset1.spChild,1) --same parameter is passed to child table.
Now i have the records in spMaster and spChild. how i create the relationship so that when i move thru Master the child have corresponding records?
I am trying to check all the checkboxes on a webform (aspx) page, which is inside a master page,depending on the ID of the checkbox. The checkboxes are created dynamically, so I only know the prefix for finding it. So, I need to find these checkboxes by iterating the controls on the page somehow. It's not working out.
My client recently got this error but I can't reproduce it on my pc. Any Idea what the problem could be. I have a master/detail scenario. So I have a grandparent/parent relationship, so when I select a product from my product combobox it displays the relevant results from the Result_Header table in my first datagridview.
Then I have a parent/child relationship so that when I select a result_header item from my first datagridview it displays the child records from the Result_detail table. If i'm adding a new Result_Header and then click save, I search for existing tests for the chosen product and insert them as new datarows into the Result_detail table. then I can update the child rows and click the second save button and it saves what I edit. Quite complicated.

I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code: Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1 AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.

I am trying to use a checkbox that is dynamically declared in an .vb file that I am trying to write into my .aspx page. I am able to write a normal checkbox of <input type='checkbox /> from the .vb Class using Response.write, but it comes up blank when using <asp:Checkbox runat='server' />I need to pass whether or not the box is checked back to the server, because I am having to either approve something if one is checked, reject something if the other is checked or do nothing if neither are checked.
Ok so with my program i'm trying to create a save configuration I have it in my context menu so that I can click save configuration and what i want it to do is check to see what check boxes are checked and save those to a file (i.e. a notepad file or whatever works) that way I can save categories for customers or my own computer or whatever and than i'll just click load and choose the category I want and it will load the checkboxes that I want to install. I found a similar post but it's not really making sense to me. So i'm wondering what I need to do to make this work.
I'm also wondering how i'm going to load the configuration but I might have to wait on that one step at a time.

I am creating a program that allows a person to enter details about their farm, stock, and machinery in order to electronically keep track of all of the information. I have created the forms and done all the coding for the data entry, and now what I would like to do is allow the user to delete a single record from the .dat file. I am able to delete it from the LstBox (using a "Delete Entry" btn coded simply with
(using the vehicles section for examples)), but I am unsure of how to delete it from the .dat file as well, to prevent it reloading upon data change / program reload. Also I would like to be able to have a reminder come up on the program start up that gives a reminder to (in the vehicles instance)when a vehicles rego is due, the date being associated to a date that is entered into the same lstbox data using a datetimepicker.
